WEBVTT 00:00:19.570 --> 00:00:23.129 Welcome back to another episode of Your Mom on 00:00:23.129 --> 00:00:26.129 Drugs. My name is Josh Klaus and I'm here with 00:00:26.129 --> 00:00:30.379 my mom. I'm Jennifer Seltzer. My mom is a PharmD, 00:00:30.480 --> 00:00:34.560 a doctor of pharmacy. I am a lowly undergraduate 00:00:34.560 --> 00:00:37.880 in neurobiology, as well as my master's in public 00:00:37.880 --> 00:00:40.939 health. And we are here to basically talk to 00:00:40.939 --> 00:00:44.299 you about drugs, usually the kind that get prescribed 00:00:44.299 --> 00:00:46.880 to you, you can take over the counter. And what 00:00:46.880 --> 00:00:48.859 they do to you, what they don't do to you, et 00:00:48.859 --> 00:00:52.299 cetera. And we are both in Texas and the summer 00:00:52.299 --> 00:00:57.479 has been incredibly hot. Incredibly hot. So we 00:00:57.479 --> 00:00:59.920 figured we would do an episode on sunscreen and 00:00:59.920 --> 00:01:02.939 sunscreen is one of those things that I know 00:01:02.939 --> 00:01:06.439 can be a bit divisive. I think a lot of people 00:01:06.439 --> 00:01:09.519 are like, well, you know, what SPF should I use? 00:01:09.599 --> 00:01:12.180 How much should I use? What brand should I use? 00:01:12.260 --> 00:01:14.719 Which types are good? I'm, you know. There are 00:01:14.719 --> 00:01:16.840 so many questions that I never thought to ask 00:01:16.840 --> 00:01:20.560 until we decided to do an episode on sunscreen 00:01:20.560 --> 00:01:25.840 to get some sun protection. And so we should 00:01:25.840 --> 00:01:29.439 talk about, you know, sunscreen. First of all, 00:01:29.439 --> 00:01:33.400 why do we use it? So mom, I'm going to turn that 00:01:33.400 --> 00:01:35.620 over to you. So what is the, what's the point 00:01:35.620 --> 00:01:38.170 of sunscreen? Well, I think we need to first 00:01:38.170 --> 00:01:42.469 go back to, like you said, why on earth do we 00:01:42.469 --> 00:01:45.390 need it? And I think it all starts with ultraviolet 00:01:45.390 --> 00:01:49.349 radiation that's coming from the sun. And it 00:01:49.349 --> 00:01:54.030 comes down and constant exposure to ultraviolet 00:01:54.030 --> 00:01:58.629 radiation, if it's cumulative, can cause long 00:01:58.629 --> 00:02:02.530 -term problems. And the problems that it can 00:02:02.530 --> 00:02:04.989 cause... You can have sunburn. That's more of 00:02:04.989 --> 00:02:08.669 an acute problem. But the long -term problems 00:02:08.669 --> 00:02:14.870 that you'll see with continual exposure to ultraviolet 00:02:14.870 --> 00:02:18.909 radiation are what they call photoaggravated 00:02:18.909 --> 00:02:22.270 skin disorders. So it's going to be premature 00:02:22.270 --> 00:02:26.689 aging of your skin as well as skin cancer. And 00:02:26.689 --> 00:02:29.979 interestingly, as I was doing this... you know, 00:02:29.979 --> 00:02:32.819 preparing for this presentation, also exposure 00:02:32.819 --> 00:02:38.599 to these, these ultraviolet wavelengths can cause 00:02:38.599 --> 00:02:41.139 cataracts too. And so, which I thought was quite 00:02:41.139 --> 00:02:43.740 interesting. So there, so again, we're wanting 00:02:43.740 --> 00:02:46.680 to do the, and you know, when, when you were 00:02:46.680 --> 00:02:50.620 a kid and when I was a kid, especially when I 00:02:50.620 --> 00:02:53.460 was a kid, the focus of putting on sunscreen 00:02:53.460 --> 00:02:56.680 was definitely not there. And it started, you 00:02:56.680 --> 00:03:00.139 know, probably as I'm a parent to your generation 00:03:00.139 --> 00:03:02.439 and it's certainly gotten progressively better 00:03:02.439 --> 00:03:05.759 since that time. So sunscreen is definitely one 00:03:05.759 --> 00:03:08.439 component that can be used to help protect people 00:03:08.439 --> 00:03:12.319 from the effects of ultraviolet radiation. So 00:03:12.319 --> 00:03:14.860 let's talk before, I know you've got a question, 00:03:14.979 --> 00:03:17.159 but let me, before you ask my question, let me 00:03:17.159 --> 00:03:20.169 just talk about the, the different types of ultraviolet 00:03:20.169 --> 00:03:25.990 radiation. There are three bands of UV light. 00:03:26.229 --> 00:03:31.830 They are UVC, ultraviolet C, ultraviolet B, and 00:03:31.830 --> 00:03:36.389 ultraviolet A. Ultraviolet C has the shortest 00:03:36.389 --> 00:03:39.849 wavelength, and then ultraviolet B, and then 00:03:39.849 --> 00:03:42.759 ultraviolet A. And we should clarify for wavelength, 00:03:42.960 --> 00:03:44.879 it's very much like what you think about like 00:03:44.879 --> 00:03:48.080 an ocean wave, like the top of one crest to the 00:03:48.080 --> 00:03:51.000 wave to the other crest. That is what we call 00:03:51.000 --> 00:03:54.400 wavelength. And there is a relationship between 00:03:54.400 --> 00:03:57.259 the length between two waves, the wavelength, 00:03:57.460 --> 00:04:00.879 the shorter it is, the more energy it carries. 00:04:01.259 --> 00:04:04.419 So light is in a, we call it the electromagnetic 00:04:04.419 --> 00:04:08.000 spectrum and the spectrum covers radio waves. 00:04:08.539 --> 00:04:10.759 which have the longest wavelength. Their wavelength 00:04:10.759 --> 00:04:12.620 can actually be the size of a house. They're 00:04:12.620 --> 00:04:15.599 very long. And then it goes all the way down 00:04:15.599 --> 00:04:18.220 to things called gamma rays, which their wavelengths 00:04:18.220 --> 00:04:20.879 are incredibly short in the terms of billions, 00:04:20.959 --> 00:04:26.600 if not trillions of a meter. And UV light is 00:04:26.600 --> 00:04:30.100 in the nanometer, in the hundreds of billions 00:04:30.100 --> 00:04:34.079 of meters. So it's incredibly small wavelengths 00:04:34.079 --> 00:04:36.529 and they can... pack quite a bit of an energetic 00:04:36.529 --> 00:04:42.290 punch so these bands uvc b and a are broken up 00:04:42.290 --> 00:04:45.110 in terms of their wavelength just the way that 00:04:45.110 --> 00:04:48.410 red orange and yellow and the colors and the 00:04:48.410 --> 00:04:50.509 visible spectrum are broken up because red is 00:04:50.509 --> 00:04:53.269 a certain wavelength of light so is orange and 00:04:53.269 --> 00:04:55.490 so is yellow so we're dividing them is do i have 00:04:55.490 --> 00:04:59.290 that correct right okay interestingly although 00:04:59.290 --> 00:05:03.769 like you like like josh said the uvc wavelength 00:05:03.769 --> 00:05:07.829 or the radiation from ultraviolet C. It's the 00:05:07.829 --> 00:05:11.610 highest energy, shortest wavelength, but most 00:05:11.610 --> 00:05:15.350 of UVC light is blocked out by the ozone layer 00:05:15.350 --> 00:05:17.709 in our atmosphere. So we don't really get the 00:05:17.709 --> 00:05:19.889 effects of it so much because it gets blocked 00:05:19.889 --> 00:05:23.209 out. So the ones that we're most concerned with 00:05:23.209 --> 00:05:26.970 are going to be UVB and UVA. It used to be thought 00:05:26.970 --> 00:05:32.350 that only UV... B was a contributory factor to 00:05:32.350 --> 00:05:34.610 skin cancer, but now it's also been found that 00:05:34.610 --> 00:05:38.509 UVA also is as well too. And other thing too 00:05:38.509 --> 00:05:41.629 that some people might be thinking about is, 00:05:41.810 --> 00:05:46.189 well, isn't UVB associated with vitamin D conversion 00:05:46.189 --> 00:05:51.000 as well? And the answer is yes. It does allow 00:05:51.000 --> 00:05:54.839 the vitamin D in our skin to get converted to 00:05:54.839 --> 00:05:57.759 the active form so that we have good bone health. 00:05:58.040 --> 00:06:01.579 But we have so many foods now that are vitamin 00:06:01.579 --> 00:06:07.899 D fortified that sun exposure is not as imperative 00:06:07.899 --> 00:06:11.060 anymore as it used to be. So that's kind of a 00:06:11.060 --> 00:06:13.449 good thing to know as well, too. Yes. And I know 00:06:13.449 --> 00:06:15.290 that there are people out there who have genetic 00:06:15.290 --> 00:06:18.930 deficiencies in forming vitamin D from the sun 00:06:18.930 --> 00:06:21.110 as well. And so those people have to get it from 00:06:21.110 --> 00:06:25.149 their diet as well. And I think it also impairs 00:06:25.149 --> 00:06:30.250 your ability to make vitamin D when you're blocking 00:06:30.250 --> 00:06:36.319 UVB exposure. We're going to talk about this 00:06:36.319 --> 00:06:39.000 later, but it really depends on the UV index 00:06:39.000 --> 00:06:42.139 and basically how prone you are to the intensity 00:06:42.139 --> 00:06:45.319 of these UV rays. And definitely early in the 00:06:45.319 --> 00:06:47.379 day and later in the day, you should be getting 00:06:47.379 --> 00:06:51.279 natural light exposure for just different biological 00:06:51.279 --> 00:06:54.540 pathways to be activated inside of your brain, 00:06:54.639 --> 00:06:57.540 mainly having to do with your circadian rhythm. 00:06:58.620 --> 00:07:01.790 There's a guy who's... who's super famous his 00:07:01.790 --> 00:07:04.209 name is andrew huberman and he talks very much 00:07:04.209 --> 00:07:07.189 about getting early and late light exposure and 00:07:07.189 --> 00:07:09.389 you definitely need some natural light exposure 00:07:09.389 --> 00:07:12.769 but if you're going to be in the sun for an extended 00:07:12.769 --> 00:07:16.610 period of time and you want to lower the odds 00:07:16.610 --> 00:07:19.350 of getting these long -term you know photo aging 00:07:19.350 --> 00:07:23.569 effects then applying sunscreen is going to be 00:07:23.569 --> 00:07:26.519 a good way to mitigating against that risk. And 00:07:26.519 --> 00:07:29.259 if you care about vitamin D as well, like mom 00:07:29.259 --> 00:07:31.660 said, you can definitely supplement that with 00:07:31.660 --> 00:07:35.439 some vitamin D. Right. One other thing, let me 00:07:35.439 --> 00:07:37.220 just add, as we're giving kind of this background 00:07:37.220 --> 00:07:41.660 information is the UVB light is the light that 00:07:41.660 --> 00:07:44.860 is most associated with getting the redness or 00:07:44.860 --> 00:07:47.360 the erythema that's associated with a sunburn 00:07:47.360 --> 00:07:52.240 and stuff. And so, but it's not just that, but 00:07:52.240 --> 00:07:55.259 because of that, it can also cause Skin cancer. 00:07:55.360 --> 00:08:01.360 I've got one fun, fun, sobering fact. In one 00:08:01.360 --> 00:08:05.430 study. It showed that if you have five or more 00:08:05.430 --> 00:08:08.829 blistering sunburns, and we've all had that awful 00:08:08.829 --> 00:08:11.329 sunburn that we're like, oh my gosh, this really 00:08:11.329 --> 00:08:15.149 hurts. If you have five or more of those between 00:08:15.149 --> 00:08:19.110 the ages of 15 and 20 years of age, it increases 00:08:19.110 --> 00:08:23.649 your risk of melanoma by 80 % and the risk of 00:08:23.649 --> 00:08:27.310 a non -melanoma skin cancer by 68%. Now that 00:08:27.310 --> 00:08:31.079 was one study, you know, and I... confess that 00:08:31.079 --> 00:08:33.580 i didn't read all the details of the study and 00:08:33.580 --> 00:08:36.100 stuff but yeah because i because i could see 00:08:36.100 --> 00:08:42.120 that as being people who are essentially just 00:08:42.120 --> 00:08:45.139 out in the sun and if you've gotten five more 00:08:45.139 --> 00:08:47.580 of those intense burns you're probably a person 00:08:47.580 --> 00:08:50.419 who's just going to be going outside and not 00:08:50.419 --> 00:08:53.000 really applying a sunscreen right if you're out 00:08:53.000 --> 00:08:54.759 if you're a guy and you're out with it out of 00:08:54.759 --> 00:08:56.700 shirt all and you get a huge sunburn on your 00:08:56.700 --> 00:08:58.960 back or whatever and stuff so yeah so i you know 00:08:58.960 --> 00:09:02.340 again just And again, I say that just for effect 00:09:02.340 --> 00:09:06.159 and the fact that it's, you know, having protection 00:09:06.159 --> 00:09:09.000 against the sun is important. It doesn't mean 00:09:09.000 --> 00:09:11.240 you don't get to go outside. It just means we 00:09:11.240 --> 00:09:13.419 need to be wise while we do it. Correct. And 00:09:13.419 --> 00:09:15.799 we are definitely talking about quality of life. 00:09:15.820 --> 00:09:18.600 I mean, because the best way to avoid sun exposure 00:09:18.600 --> 00:09:21.440 is to stay out of the sun. But who wants to do 00:09:21.440 --> 00:09:23.879 that? There's so much beautiful life to experience. 00:09:24.629 --> 00:09:27.309 Um, yeah, you can also wear clothing. That's 00:09:27.309 --> 00:09:29.230 probably the best way to do it. Uh, but you're 00:09:29.230 --> 00:09:30.909 not going to wear long clothes all the time, 00:09:30.990 --> 00:09:33.990 especially in a summer in Texas. Um, and again, 00:09:34.090 --> 00:09:36.730 like when we're talking about risk, um, these 00:09:36.730 --> 00:09:38.970 are not binary outcomes. You know, anytime you're 00:09:38.970 --> 00:09:41.269 talking about things like sunburn or cancer or 00:09:41.269 --> 00:09:44.250 any type of disease state, it is going to be 00:09:44.250 --> 00:09:47.230 a risk that you're going to accrue because you'll 00:09:47.230 --> 00:09:49.389 always hear the person, especially about cigarettes, 00:09:49.590 --> 00:09:51.309 be like, well, my grandmother smoked cigarettes 00:09:51.309 --> 00:09:53.490 and she lived to be 102. It's like, okay, well. 00:09:54.120 --> 00:09:56.220 She dodged the bullet, but there's hundreds of 00:09:56.220 --> 00:09:58.779 thousands of people who didn't. And so anytime 00:09:58.779 --> 00:10:02.039 that you're exposing your body to certain chemicals, 00:10:02.120 --> 00:10:06.539 you are essentially just playing roulette with 00:10:06.539 --> 00:10:09.679 some damage that could potentially be done to 00:10:09.679 --> 00:10:12.080 your DNA that will eventually cause cancer. But 00:10:12.080 --> 00:10:13.480 we're going to get to cancer in a bit, and I 00:10:13.480 --> 00:10:15.200 think we should start with the low -hanging fruit 00:10:15.200 --> 00:10:17.639 because this will actually kind of lead us into 00:10:17.639 --> 00:10:21.019 talking about how SPFs are created, but let's 00:10:21.019 --> 00:10:24.159 talk about sunburn. And that's definitely arrhythmia 00:10:24.159 --> 00:10:28.480 is the, not arrhythmia, it's erythema. Erythema. 00:10:28.679 --> 00:10:31.279 Erythema. Not arrhythmia. Not arrhythmia. That's 00:10:31.279 --> 00:10:34.639 a hard thing. So, yeah. Let me just give you 00:10:34.639 --> 00:10:36.259 some other little kind of interesting pearls 00:10:36.259 --> 00:10:38.820 as well, too, about kind of that relate to sunburn. 00:10:39.240 --> 00:10:42.059 Some people might think that they don't need 00:10:42.059 --> 00:10:44.399 to use any protection if the clouds are out. 00:10:45.259 --> 00:10:48.159 But that is not true. The sun can still penetrate. 00:10:48.320 --> 00:10:51.120 These UVA and UVB lights can still penetrate 00:10:51.120 --> 00:10:53.519 through clouds, maybe not as much, but they're 00:10:53.519 --> 00:10:56.700 still there. So we need to be aware of that as 00:10:56.700 --> 00:10:59.340 well, too. And this was a really interesting 00:10:59.340 --> 00:11:01.779 thing that I learned as well, too, as I'm preparing 00:11:01.779 --> 00:11:03.980 this, because Josh and I always learn new things 00:11:03.980 --> 00:11:10.139 while we're doing this. Water, water only reflects 00:11:10.139 --> 00:11:15.200 about 5%. of ultraviolet radiation. And what 00:11:15.200 --> 00:11:17.259 I mean by that is that it's going to move it 00:11:17.259 --> 00:11:19.220 away from you so that you're protected against 00:11:19.220 --> 00:11:27.200 the sun. So that means that 95 % of the UV radiation 00:11:27.200 --> 00:11:32.100 light from the sun can penetrate water. So that 00:11:32.100 --> 00:11:35.559 means that you want to have sunscreen on while 00:11:35.559 --> 00:11:38.100 you're in the water. And you also want to count 00:11:38.100 --> 00:11:41.809 that as part of the time that you are being protected 00:11:41.809 --> 00:11:44.529 against the sun as far as reapplication processes 00:11:44.529 --> 00:11:46.529 with the sunscreen that we'll talk about in a 00:11:46.529 --> 00:11:50.070 bit. So again, water is not a protector against 00:11:50.070 --> 00:11:54.370 the sun. Also, like Josh said, dry, dry clothings 00:11:54.370 --> 00:11:56.129 will reflect most of it unless you're wearing 00:11:56.129 --> 00:11:59.950 something really thin that might, you know, cause 00:11:59.950 --> 00:12:02.690 the sun to penetrate through. So you got to be, 00:12:02.730 --> 00:12:06.549 just be aware of what you've got on. And interestingly, 00:12:06.710 --> 00:12:10.490 the windshields in cars. are designed to protect 00:12:10.490 --> 00:12:14.629 you against UV light, but the side windows aren't. 00:12:14.730 --> 00:12:18.909 So if you have some sort of a sensitive, you 00:12:18.909 --> 00:12:21.990 know, skin condition, or maybe you're taking 00:12:21.990 --> 00:12:24.990 a medication that causes you to be more sensitive 00:12:24.990 --> 00:12:29.049 to light, then you might consider putting on 00:12:29.049 --> 00:12:30.889 sunscreen even while you're riding in a car. 00:12:31.049 --> 00:12:33.870 Well, I think we should talk about sunburn in 00:12:33.870 --> 00:12:36.230 general. Like, I think a lot of people think 00:12:36.230 --> 00:12:40.649 that the mechanism of getting sunburned and getting 00:12:40.649 --> 00:12:43.649 skin cancer are, are the same or synonymous, 00:12:43.710 --> 00:12:47.269 even though the cause might be related. So I 00:12:47.269 --> 00:12:50.190 think it would be good to talk about that, um, 00:12:50.549 --> 00:12:56.210 in terms of, you know, what is sunburn? Um, and, 00:12:56.330 --> 00:12:59.009 um, and I can definitely speak to that if, and 00:12:59.009 --> 00:13:00.929 it's like, I've got a little bit, but I bet you 00:13:00.929 --> 00:13:02.529 can add a lot. Yeah. You can add some context. 00:13:02.570 --> 00:13:04.970 So let's differentiate. Cause I think a lot of 00:13:04.970 --> 00:13:07.860 people, when they put on sunscreen, They're thinking, 00:13:07.940 --> 00:13:10.960 oh, I'm putting this on either to prevent me 00:13:10.960 --> 00:13:13.799 from getting sunburn or to diminish my risk of 00:13:13.799 --> 00:13:16.100 potentially getting a melanoma or carcinoma. 00:13:16.639 --> 00:13:19.360 And we'll talk about what each of those means. 00:13:19.460 --> 00:13:22.480 Let's go with sunburn. So if you think about 00:13:22.480 --> 00:13:26.659 your skin, your skin is not just one thing. It's 00:13:26.659 --> 00:13:31.259 a layer of things. And you have something called 00:13:31.259 --> 00:13:34.320 your epidermis, which is the thin outer layer 00:13:34.320 --> 00:13:36.000 of your skin. It's super thin. It's actually 00:13:36.000 --> 00:13:39.799 only a couple of cell layers thick. And as a 00:13:39.799 --> 00:13:42.799 reminder of what a cell is, a cell, your body 00:13:42.799 --> 00:13:44.720 is composed of cells and they're essentially 00:13:44.720 --> 00:13:50.860 these spherical or circular entities that contain 00:13:50.860 --> 00:13:54.360 this very liquid inside that's mostly composed 00:13:54.360 --> 00:13:59.799 of protein. and nucleic acids, fats, and sugars. 00:13:59.919 --> 00:14:02.139 And nucleic acids are things like DNA, which 00:14:02.139 --> 00:14:04.639 is your genetic information. So your body has 00:14:04.639 --> 00:14:08.039 about 100 trillion of these. And there's different 00:14:08.039 --> 00:14:09.960 types all throughout your body that do different 00:14:09.960 --> 00:14:15.259 jobs. So the job of your epidermis is it's this 00:14:15.259 --> 00:14:19.000 dead layer of cells because they're no longer 00:14:19.000 --> 00:14:21.820 living, but they still have this protective barrier 00:14:21.820 --> 00:14:24.039 around. But they have no blood vessels because 00:14:24.039 --> 00:14:26.460 they're dead. They don't need blood. So you don't 00:14:26.460 --> 00:14:30.120 need that. So actually, when you get sunburned, 00:14:30.120 --> 00:14:34.480 that UV light is essentially getting through 00:14:34.480 --> 00:14:37.000 your epidermis because the wavelength of the 00:14:37.000 --> 00:14:39.259 UV light is so small that it can get through 00:14:39.259 --> 00:14:41.879 that epidermis. And it can actually stimulate 00:14:41.879 --> 00:14:45.220 blood flow from your dermis, which is just below 00:14:45.220 --> 00:14:48.379 your epidermis. And that can stimulate a massive 00:14:48.379 --> 00:14:51.860 amount of blood flow that basically creates this 00:14:51.860 --> 00:14:55.820 pinkish hue. And if that gets stimulated enough, 00:14:55.980 --> 00:14:58.120 you're essentially going to get kind of this 00:14:58.120 --> 00:15:01.259 red cooking effect, which is what we call a sunburn. 00:15:01.360 --> 00:15:03.080 And it's kind of when you've lost a lot of the 00:15:03.080 --> 00:15:06.419 water that's in your skin. as well as increased 00:15:06.419 --> 00:15:08.340 blood flow to that area. And it's very uncomfortable 00:15:08.340 --> 00:15:12.440 because there's also a large immune response 00:15:12.440 --> 00:15:14.700 to that as well. We have a lot of cytokines, 00:15:14.700 --> 00:15:16.860 which are these cells in your immune system that 00:15:16.860 --> 00:15:19.019 rush to that area, and that's why it hurts. It's 00:15:19.019 --> 00:15:22.559 creating this inflammation effect going to your 00:15:22.559 --> 00:15:25.960 skin and your sunburn. And we call that erythema, 00:15:26.100 --> 00:15:30.039 which is that effect of moving blood from basically 00:15:30.039 --> 00:15:33.399 this dermal area kind of in between to the epidermal 00:15:33.399 --> 00:15:36.000 area. Anything to add to that, mom? The only 00:15:36.000 --> 00:15:39.460 thing I would add to that is that some sunburns 00:15:39.460 --> 00:15:42.080 can be really severe and people can get really 00:15:42.080 --> 00:15:45.159 sick. If you get really, you think about a burn, 00:15:45.240 --> 00:15:47.679 if you got burned by fire, you know, and stuff. 00:15:47.740 --> 00:15:49.980 Well, I mean, some people can blister. I mean, 00:15:50.000 --> 00:15:51.740 you can have some swelling with your sunburn, 00:15:51.820 --> 00:15:54.720 but you can also get fever chills and even shock 00:15:54.720 --> 00:15:57.879 because you've lost so much. You've got, you've 00:15:57.879 --> 00:16:00.970 had, you've had such a. increase in your body 00:16:00.970 --> 00:16:03.389 heat as a result of the sun hitting it so that 00:16:03.389 --> 00:16:06.230 we don't see that that often but again it's just 00:16:06.230 --> 00:16:08.149 something to be aware of especially with you 00:16:08.149 --> 00:16:10.149 know your younger children and stuff and just 00:16:10.149 --> 00:16:12.750 to make sure that you know you do protect them 00:16:12.750 --> 00:16:15.870 because they could you know get you know sunburn 00:16:15.870 --> 00:16:18.529 maybe even worse than than we are because of 00:16:18.529 --> 00:16:20.669 their little delicate new little skin and stuff 00:16:20.669 --> 00:16:23.690 so um so i would just add that as far as the 00:16:23.690 --> 00:16:26.450 sunburn is concerned yeah and i think from this 00:16:26.940 --> 00:16:31.279 sunburn part we should talk about you know i 00:16:31.279 --> 00:16:33.419 think a lot of people are like well now okay 00:16:33.419 --> 00:16:35.279 i want to stop from getting burned that doesn't 00:16:35.279 --> 00:16:38.519 sound very good what spf should i use and what 00:16:38.519 --> 00:16:42.200 is spf in general so i think we should talk about 00:16:42.200 --> 00:16:44.679 how spf is defined because i think it's a little 00:16:44.679 --> 00:16:47.700 counterintuitive or people don't really aren't 00:16:47.700 --> 00:16:52.830 really aware of how it's calculated um So mom, 00:16:52.870 --> 00:16:55.950 you can fill in my gaps wherever, but so SPF 00:16:55.950 --> 00:16:59.769 stands for sun protection factor. And when a 00:16:59.769 --> 00:17:03.450 sunscreen manufacturer is creating a sunscreen, 00:17:03.690 --> 00:17:07.049 what they'll normally do is they will get a test 00:17:07.049 --> 00:17:11.650 subject. And usually it's a light skinned person. 00:17:11.829 --> 00:17:14.269 So usually someone of Caucasian descent, and 00:17:14.269 --> 00:17:17.190 they will expose parts of their skin, usually 00:17:17.190 --> 00:17:20.970 on their back to UV radiation. And then they 00:17:20.970 --> 00:17:24.019 will see, basically the energy that it takes 00:17:24.019 --> 00:17:26.920 to turn that skin pink. And then they will send 00:17:26.920 --> 00:17:29.339 that person home. And then the next day, that 00:17:29.339 --> 00:17:33.059 same person comes back and they apply basically 00:17:33.059 --> 00:17:37.299 a healthy dose of sunscreen on the other side 00:17:37.299 --> 00:17:39.660 of the back, maybe their left side instead of 00:17:39.660 --> 00:17:42.079 their right side. And they expose them to UV 00:17:42.079 --> 00:17:47.299 radiation. And then they do that until they turn 00:17:47.299 --> 00:17:50.450 pink. And then They come back the third day to 00:17:50.450 --> 00:17:55.109 compare the two and the energy that it took to 00:17:55.109 --> 00:17:58.569 basically cause the skin to turn pink on the 00:17:58.569 --> 00:18:03.069 sunscreen application side versus the non -sunscreen 00:18:03.069 --> 00:18:06.390 application side, they divide that number. So 00:18:06.390 --> 00:18:10.509 for example, if it took 250 units of UV light 00:18:10.509 --> 00:18:14.509 on the left side with the sunscreen and it took 00:18:14.509 --> 00:18:19.400 10 units, on the side with no sunscreen, you 00:18:19.400 --> 00:18:23.400 would divide 250 divided by 10 and you would 00:18:23.400 --> 00:18:28.559 get 25. And so that would be an SPF of 25. Now 00:18:28.559 --> 00:18:31.039 they do this with multiple people so you can 00:18:31.039 --> 00:18:33.440 get an average. So an SPF is just an average 00:18:33.440 --> 00:18:37.519 of this between the people. But you can imagine 00:18:37.519 --> 00:18:40.859 that it's incredibly variable. You can have someone 00:18:40.859 --> 00:18:44.559 who's super tan. Who's get brought in and their 00:18:44.559 --> 00:18:46.740 SPF is going to be different than someone who 00:18:46.740 --> 00:18:49.799 is super pale. So your SPF actually depends. 00:18:49.940 --> 00:18:51.859 It's really personal. So it actually depends 00:18:51.859 --> 00:18:53.960 very much on your skin tone. People who have 00:18:53.960 --> 00:18:55.960 darker skin tones are going to have a higher 00:18:55.960 --> 00:18:59.140 individual SPF than someone who's Caucasian. 00:19:00.160 --> 00:19:03.400 Anything to fill in there, mom? A couple of things. 00:19:04.059 --> 00:19:07.180 That number that when he's, when Josh is talking 00:19:07.180 --> 00:19:11.470 about. that dose of UV light to cause that red, 00:19:11.470 --> 00:19:15.009 red, the, the skin turning red on that test subject, 00:19:15.109 --> 00:19:18.990 they call that the minimum erythema dose. So 00:19:18.990 --> 00:19:22.349 not that you, anybody, but just the med, that's 00:19:22.349 --> 00:19:26.509 right. And then another thing to add to that 00:19:26.509 --> 00:19:29.089 is that, you know, we talked about sunburn, but 00:19:29.089 --> 00:19:31.670 let's just make mention one, a few things about 00:19:31.670 --> 00:19:35.160 sun, sun tanning, you know, because When I was 00:19:35.160 --> 00:19:38.539 young, that was the focus of my life was to get 00:19:38.539 --> 00:19:40.960 a suntan. And I wish I'd listened to my father. 00:19:42.400 --> 00:19:46.640 Was he telling you don't do it? Oh, yes. My nose 00:19:46.640 --> 00:19:48.519 peeled and burned. I don't know how many times. 00:19:49.200 --> 00:19:54.099 So ultraviolet radiation stimulates melanocytes. 00:19:54.259 --> 00:19:56.299 Those are the cells. And Josh is going to do 00:19:56.299 --> 00:19:58.160 a better job of describing the cells than I do. 00:19:58.200 --> 00:20:01.259 But they have the color in our skin. And so the 00:20:01.259 --> 00:20:05.539 ultraviolet radiation. And some of us have more 00:20:05.539 --> 00:20:08.079 of those than others that can be activated. And 00:20:08.079 --> 00:20:10.839 so that's responsible for us tanning so that 00:20:10.839 --> 00:20:13.880 the light from the sun will stimulate that and 00:20:13.880 --> 00:20:16.980 it redistributes melanin in our skin. And so 00:20:16.980 --> 00:20:19.640 we get changes in our skin color because of that. 00:20:20.720 --> 00:20:25.539 And UVA and UVB both contribute to sun tanning. 00:20:25.619 --> 00:20:29.740 But please listen to this. Tanning does not protect 00:20:29.740 --> 00:20:33.640 you from skin cancer or premature aging. It's 00:20:33.640 --> 00:20:37.579 just one of those factors that you just have 00:20:37.579 --> 00:20:40.440 because you have more melanocytes. It also doesn't 00:20:40.440 --> 00:20:42.799 protect you from future sunburns as well either. 00:20:43.980 --> 00:20:49.700 Well, that's surprising. But wouldn't it, like 00:20:49.700 --> 00:20:54.440 if you were more tan than someone who is pale, 00:20:54.700 --> 00:20:57.750 wouldn't it take a longer time? For you to get 00:20:57.750 --> 00:20:59.829 sunburned. Yeah, I'm not saying that it couldn't 00:20:59.829 --> 00:21:01.990 delay the sunburn, but it doesn't prevent you 00:21:01.990 --> 00:21:03.549 from getting sunburned. That's true, because 00:21:03.549 --> 00:21:06.329 I know that people who have black skin can also 00:21:06.329 --> 00:21:08.750 get sunburned. They can. And they're all, you 00:21:08.750 --> 00:21:12.049 know, those with darker skin, they are not precluded 00:21:12.049 --> 00:21:14.349 from getting skin cancer at some point down the 00:21:14.349 --> 00:21:17.690 future. So if you're, I mean, again, you're applying 00:21:17.690 --> 00:21:22.029 sunscreen for multifaceted reasons to prevent 00:21:22.029 --> 00:21:25.529 sunburn in a lot of us and also to prevent those. 00:21:25.829 --> 00:21:28.630 that premature aging as well as skin cancer down 00:21:28.630 --> 00:21:30.769 the road. Yeah. And we should talk about premature 00:21:30.769 --> 00:21:34.329 aging for a bit. Like what is aging? I think 00:21:34.329 --> 00:21:36.009 that's a catch -all term, but when we're talking 00:21:36.009 --> 00:21:39.869 about that, we are talking about, there's no 00:21:39.869 --> 00:21:42.230 way to put it. This is looking old and it's this, 00:21:42.250 --> 00:21:44.829 that you have these, you have a couple of proteins 00:21:44.829 --> 00:21:47.509 in your skin that really promote to the tightening 00:21:47.509 --> 00:21:50.990 of your skin. The main one is collagen. The other 00:21:50.990 --> 00:21:54.650 one is elastin. Um, and collagen, you've probably 00:21:54.650 --> 00:21:56.829 heard this before, either, you know, from, you 00:21:56.829 --> 00:21:59.789 know, doing Botox injections or even you can, 00:21:59.829 --> 00:22:02.549 you can ingest collagen, um, by eating things 00:22:02.549 --> 00:22:06.390 like jello, like gelatin is a derivative of collagen. 00:22:06.569 --> 00:22:12.150 Um, and when the UV light is essentially shining 00:22:12.150 --> 00:22:16.079 on your face. It does damage to that protein 00:22:16.079 --> 00:22:18.420 and essentially loses its collagen as a great 00:22:18.420 --> 00:22:20.960 water absorber. So it essentially, it takes a 00:22:20.960 --> 00:22:24.140 lot of water from your body and it kind of makes 00:22:24.140 --> 00:22:26.680 it your, your face kind of balloon out, but in 00:22:26.680 --> 00:22:28.400 a good way, it makes everything look really tight. 00:22:28.640 --> 00:22:31.859 But once it loses its ability to do that, your 00:22:31.859 --> 00:22:34.079 skin starts to sag a bit. So when you see an 00:22:34.079 --> 00:22:37.799 older person like myself, as I'm, as I look in 00:22:37.799 --> 00:22:40.019 the mirror every day, you see the tightness kind 00:22:40.019 --> 00:22:44.589 of going away. Funny enough, if you look at an 00:22:44.589 --> 00:22:48.309 old person's skin on a place that doesn't get 00:22:48.309 --> 00:22:50.829 exposed to a lot of sun, like maybe underneath 00:22:50.829 --> 00:22:54.190 their pants, their skin is just as elastic as 00:22:54.190 --> 00:22:57.029 a young person's. It really does have to do with 00:22:57.029 --> 00:22:59.470 sun exposure and sun damage. If you really want 00:22:59.470 --> 00:23:03.829 to prevent that aging look, it is really a good 00:23:03.829 --> 00:23:06.349 idea to put especially sunscreen on your face 00:23:06.349 --> 00:23:08.930 and a good sunscreen. We'll talk about what a 00:23:08.930 --> 00:23:11.960 good sunscreen is a bit later. You're thinking, 00:23:12.019 --> 00:23:17.079 okay, so the higher the SPF, the better. Or maybe 00:23:17.079 --> 00:23:19.440 I'm thinking for you. But the answer is yes. 00:23:19.480 --> 00:23:21.640 The higher the SPF, the better. And there's been 00:23:21.640 --> 00:23:25.119 this myth that's gone around that is like, well, 00:23:25.240 --> 00:23:28.960 there's a marginal difference between SPF 50 00:23:28.960 --> 00:23:32.259 and SPF 25, for example. Because if you divide 00:23:32.259 --> 00:23:35.599 one over 50, you're going to basically block 00:23:35.599 --> 00:23:40.859 out 98 % of the rays. SPF 25, it's one divided 00:23:40.859 --> 00:23:43.960 by 25 and you'll block out like 96. So 96 to 00:23:43.960 --> 00:23:46.019 98 is not that much, but as they actually get 00:23:46.019 --> 00:23:48.460 the math wrong, it's actually one minus those 00:23:48.460 --> 00:23:52.980 things. So essentially with the SPF 25, you might 00:23:52.980 --> 00:23:56.059 block out 6 % of the rays or you might, yeah, 00:23:56.099 --> 00:23:58.599 you might leave, you might protect yourself all 00:23:58.599 --> 00:24:02.440 but 6 % of the rays. And with one over 50, you'll 00:24:02.440 --> 00:24:05.019 block out all but 3 % of the rays. So it's actually 00:24:05.019 --> 00:24:08.180 double the amount of protection. So like you 00:24:08.180 --> 00:24:09.599 don't want to look at the large numbers. You 00:24:09.599 --> 00:24:11.240 want to look at the difference between what you're 00:24:11.240 --> 00:24:15.799 blocking out. So 6 % is twice as much as 3%. 00:24:15.799 --> 00:24:19.519 So you actually want to get a higher SPF that 00:24:19.519 --> 00:24:21.559 is comfortable for you. And actually you feel 00:24:21.559 --> 00:24:23.640 like you can apply. And that's the other thing 00:24:23.640 --> 00:24:25.839 I'm going to bring up next is that most people 00:24:25.839 --> 00:24:29.980 don't apply the amount of sunscreen that they 00:24:29.980 --> 00:24:33.500 use to generate the SPF. Like the amount of sunscreen 00:24:33.500 --> 00:24:35.990 that is used in the lab to... what we talked 00:24:35.990 --> 00:24:40.509 about with the med is like this generous dosage 00:24:40.509 --> 00:24:43.710 that no one would ever do. And it's this, and 00:24:43.710 --> 00:24:46.049 people would feel slimy and gross when they do 00:24:46.049 --> 00:24:48.910 it. So most people don't apply enough. That's 00:24:48.910 --> 00:24:52.089 a problem too. So what you want to do is knowing 00:24:52.089 --> 00:24:54.490 your comfort level with sunscreen. Let's assume 00:24:54.490 --> 00:24:57.589 that you like an SPF of 30. You should probably 00:24:57.589 --> 00:25:02.539 get an SPF of 90 because The way that most people 00:25:02.539 --> 00:25:04.960 apply sunscreen, they usually get about a third 00:25:04.960 --> 00:25:07.940 of the benefit. So you actually want to be getting 00:25:07.940 --> 00:25:10.559 something that's maybe two or three times higher 00:25:10.559 --> 00:25:13.799 than you would normally buy at the store. I did 00:25:13.799 --> 00:25:16.599 not see that confirmed in the literature, but. 00:25:17.440 --> 00:25:20.279 that, that may be a way to do it. There's also 00:25:20.279 --> 00:25:23.500 reapplying it more frequently and that's definitely, 00:25:23.500 --> 00:25:25.839 definitely recommended and stuff. And we're going 00:25:25.839 --> 00:25:28.099 to get to that, you know, in just a few minutes 00:25:28.099 --> 00:25:30.720 and stuff. So let me just, let me just reiterate 00:25:30.720 --> 00:25:34.920 what Josh was talking about as far as FPFS. PF 00:25:34.920 --> 00:25:39.579 is concerned. So while we do have this calculation 00:25:39.579 --> 00:25:43.240 to determine our sun protection factor, there 00:25:43.240 --> 00:25:47.059 are other ingredients in a sunscreen. So it's 00:25:47.059 --> 00:25:50.759 kind of a collective determination of a sun protection 00:25:50.759 --> 00:25:54.640 factor for a sunscreen. So there are a few other 00:25:54.640 --> 00:25:58.319 things. It wasn't elaborated in the literature 00:25:58.319 --> 00:26:01.220 that I looked at. But you do have a sun protection 00:26:01.220 --> 00:26:05.700 factor 15. You have one that's 30, 40, 50, and 00:26:05.700 --> 00:26:09.180 60. Above 60 is really not recommended without 00:26:09.180 --> 00:26:16.420 just more, you know, maybe you have a unique 00:26:16.420 --> 00:26:19.240 circumstance and stuff, but most of us would 00:26:19.240 --> 00:26:22.839 be able to tolerate, you know, the... You know, 00:26:22.880 --> 00:26:28.220 40s and 50s and stuff. And so the SPF 15 blocks 00:26:28.220 --> 00:26:36.079 93 % of UVB lights, UVB light. The SPF 30 blocks 00:26:36.079 --> 00:26:45.099 96 .7 % of UVB. And then SPF 40 blocks 97 .5%. 00:26:45.640 --> 00:26:47.240 Right. And what you want to do is you don't want 00:26:47.240 --> 00:26:49.079 to look at the difference. You want to look at 00:26:49.079 --> 00:26:51.599 the difference between those numbers. Yes. And 00:26:51.599 --> 00:26:55.119 is that double or triple? So like for the SPF 00:26:55.119 --> 00:27:01.420 15, if you take. 100 minus 93, you get 7%. So 00:27:01.420 --> 00:27:04.920 it's giving you a 7 % protection factor. With 00:27:04.920 --> 00:27:10.079 an SPF 40, you've got 100 minus 97 .5. So you're 00:27:10.079 --> 00:27:12.920 getting 2 .5. So then you look at the difference 00:27:12.920 --> 00:27:16.140 between 7 and 2 .5. It's almost threefold. That 00:27:16.140 --> 00:27:19.839 is correct. And so you would be so much better 00:27:19.839 --> 00:27:24.200 of getting the SPF of 40. And I know that being 00:27:24.200 --> 00:27:28.029 in the public health world, If everything worked 00:27:28.029 --> 00:27:30.190 out the way it did in clinical trials and laboratory, 00:27:30.509 --> 00:27:32.970 that would be great. But honestly, one of the 00:27:32.970 --> 00:27:36.309 problems, and my mom can attest to this, is that 00:27:36.309 --> 00:27:38.990 there is the way that theoretically things should 00:27:38.990 --> 00:27:41.289 go and there's the way that people actually take 00:27:41.289 --> 00:27:44.509 their drugs. And a lot of times when doctors 00:27:44.509 --> 00:27:46.690 prescribe medications to patients, whether it 00:27:46.690 --> 00:27:50.670 be sunscreen or any type of medication, it's 00:27:50.670 --> 00:27:54.390 hard to get the patients to take the recommended 00:27:54.390 --> 00:27:57.700 dosage. The side effects are so severe that they 00:27:57.700 --> 00:27:59.539 don't feel like they can keep up with it or they 00:27:59.539 --> 00:28:02.440 forget or it's like it's too much information 00:28:02.440 --> 00:28:05.680 all at once. So sometimes, even though in the 00:28:05.680 --> 00:28:08.339 laboratory, it says you this one thing, you have 00:28:08.339 --> 00:28:10.559 to look in the real world application and say, 00:28:10.619 --> 00:28:13.940 OK, well, if people aren't applying this sunscreen 00:28:13.940 --> 00:28:16.579 to an adequate degree. Are we going to say that 00:28:16.579 --> 00:28:18.039 you're wrong? Are we going to go to recommend, 00:28:18.220 --> 00:28:20.259 Hey, maybe you should get a higher SPF, put on 00:28:20.259 --> 00:28:21.900 the same amount and you might get the same effect. 00:28:22.079 --> 00:28:23.920 So yeah. Yeah. I think it's one of those things 00:28:23.920 --> 00:28:26.200 where you kind of have to do what's best for 00:28:26.200 --> 00:28:28.660 you. Like you'll put on an SPF and if you don't 00:28:28.660 --> 00:28:31.500 get sunburned, like, okay, you probably did a 00:28:31.500 --> 00:28:36.539 great job, um, that day. Right. Let's also talk, 00:28:36.539 --> 00:28:38.500 let's not forget to just mention just again, 00:28:38.619 --> 00:28:41.299 this is definitely not a podcast about skin cancer, 00:28:41.380 --> 00:28:45.740 but the three most common kinds of skin cancer 00:28:45.740 --> 00:28:49.240 that are associated with sun exposure are melanoma, 00:28:49.440 --> 00:28:53.619 basal cell carcinoma, and squamous cell carcinoma. 00:28:53.799 --> 00:29:00.309 In 2012, There were 3 .5 million cases of basal 00:29:00.309 --> 00:29:03.029 cell and squamous cell carcinoma diagnosed in 00:29:03.029 --> 00:29:06.509 the United States. And in 2019, there were 95 00:29:06.509 --> 00:29:11.309 ,000 melanoma cases. So you can see the discrepancy. 00:29:11.309 --> 00:29:13.869 There's a lot more of basal cell and squamous 00:29:13.869 --> 00:29:17.230 cell carcinomas. Basal cell carcinomas are limited 00:29:17.230 --> 00:29:19.990 to that. epidermis level that Josh was talking 00:29:19.990 --> 00:29:22.670 about. So that top layer of the skin, and they 00:29:22.670 --> 00:29:27.569 rarely, if ever, metastasize. Squamous cell carcinomas 00:29:27.569 --> 00:29:29.589 are going to go a little bit deeper, and they 00:29:29.589 --> 00:29:33.750 only metastasize in 4 % of patients. Can we clarify 00:29:33.750 --> 00:29:37.710 what metastasis is? So metastasis is when it 00:29:37.710 --> 00:29:41.269 spreads from that local cancer site and it can 00:29:41.269 --> 00:29:43.750 get in your bloodstream or your lymph node. And 00:29:43.750 --> 00:29:46.269 so then it gets spread out through the rest of 00:29:46.269 --> 00:29:48.289 your body. Right, because some places to have 00:29:48.289 --> 00:29:50.410 cancer are better than others. And if it's on 00:29:50.410 --> 00:29:52.930 your skin, that can be easily removed. But if 00:29:52.930 --> 00:29:55.269 it's in your liver, then that's going to be a 00:29:55.269 --> 00:29:57.430 much more invasive surgery and procedure. Right, 00:29:57.430 --> 00:30:03.529 right. And so then, like I said, melanoma, It's 00:30:03.529 --> 00:30:07.349 the most deadly of the skin cancers. And most 00:30:07.349 --> 00:30:11.839 of them arise from... from normal skin, but 30 00:30:11.839 --> 00:30:15.119 % of them can arise from moles. And remember, 00:30:15.200 --> 00:30:17.319 if you've heard about melanoma, it's got the 00:30:17.319 --> 00:30:20.859 alpha mnemonic that goes along with it, A, B, 00:30:20.900 --> 00:30:23.339 C, D, E. So again, if you're looking something 00:30:23.339 --> 00:30:26.579 on your skin and it's got what they call an asymmetric 00:30:26.579 --> 00:30:29.640 shape, so that means it's not perfectly round, 00:30:29.839 --> 00:30:33.799 it's kind of weird shaped. If its borders are 00:30:33.799 --> 00:30:37.680 irregular or not clearly defined, if it's got 00:30:37.680 --> 00:30:43.390 color variation, within the same lesion or change 00:30:43.390 --> 00:30:46.289 in color. You know, if it was one color one day 00:30:46.289 --> 00:30:47.990 and then now it's different color, you got to 00:30:47.990 --> 00:30:51.029 be concerned about that. If it's diameter, if 00:30:51.029 --> 00:30:54.190 the, if the distance across it is larger than 00:30:54.190 --> 00:30:56.890 six millimeters, so it's going to get be a little 00:30:56.890 --> 00:31:00.890 bit larger. And then if it, if it, if it. evolves 00:31:00.890 --> 00:31:04.910 or change if a mole evolves or changes you want 00:31:04.910 --> 00:31:07.589 to just contact your doctor about that and stuff 00:31:07.589 --> 00:31:09.970 so just to give you a little heads up about that 00:31:09.970 --> 00:31:12.049 well that's really good advice and for any of 00:31:12.049 --> 00:31:16.049 you uh you know word nerds out there we're talking 00:31:16.049 --> 00:31:19.650 about carcinomas versus melanoma melanoma is 00:31:19.650 --> 00:31:22.789 oma is the suffix and it stands for basically 00:31:22.789 --> 00:31:27.410 cancer and and um and then melanoma stands for 00:31:27.880 --> 00:31:30.940 basically a melanocyte or melanin, which is, 00:31:30.960 --> 00:31:33.359 as mom talked about earlier, is the pigment or 00:31:33.359 --> 00:31:36.359 the color producing cells in your skin, which 00:31:36.359 --> 00:31:38.819 cause certain people to be tan or black or brown 00:31:38.819 --> 00:31:44.119 or whatever. And then carcinoma, carcin is essentially 00:31:44.119 --> 00:31:47.420 just a catch -all term for cancer, like carcinogenic, 00:31:47.579 --> 00:31:51.079 it's cancer causing. And carcin is actually, 00:31:51.140 --> 00:31:55.200 it comes from the Greek word for crab. And because 00:31:55.200 --> 00:31:58.059 a lot of when Greeks were looking at cancerous 00:31:58.059 --> 00:32:00.099 growth on people, they say, oh, that kind of 00:32:00.099 --> 00:32:03.839 looks like a crab on the skin. And if you know 00:32:03.839 --> 00:32:06.740 anything about the zodiac signs, like the sign 00:32:06.740 --> 00:32:10.720 of the crab in the sky is cancer. And that comes 00:32:10.720 --> 00:32:13.420 from the ancient Greek or the ancient Latin and 00:32:13.420 --> 00:32:16.339 Greek for crab, which is a really interesting 00:32:16.339 --> 00:32:19.890 thing. There you go. Little pearl. So, okay. 00:32:20.049 --> 00:32:23.890 So I'll just mention very briefly, we're not 00:32:23.890 --> 00:32:27.190 going to go into this really, but know too that 00:32:27.190 --> 00:32:30.589 some medications can make you what we call photosensitive. 00:32:30.789 --> 00:32:32.430 That means you're going to be more sensitive 00:32:32.430 --> 00:32:35.609 to getting sunburned. And you could talk with 00:32:35.609 --> 00:32:37.750 your pharmacist or physician if you're prescribed 00:32:37.750 --> 00:32:39.349 one of those. And again, you're going to just 00:32:39.349 --> 00:32:42.150 want to be more sun protected if you're taking 00:32:42.150 --> 00:32:46.549 one of those. So what would be an example of 00:32:46.549 --> 00:32:49.880 a... medication that someone will be taking to 00:32:49.880 --> 00:32:53.920 make them more sensitive to the sun um tetracycline 00:32:53.920 --> 00:32:56.940 antibiotics um they definitely make you more 00:32:56.940 --> 00:33:02.779 sensitive to the sun um some um diuretics um 00:33:03.659 --> 00:33:06.640 Like furosemide that have more of a sulfur kind 00:33:06.640 --> 00:33:08.880 of component in it. It's going to make you more 00:33:08.880 --> 00:33:11.160 sensitive to the sun as well, too. There's a 00:33:11.160 --> 00:33:13.420 long list of them. I'm sorry. I don't have it 00:33:13.420 --> 00:33:15.680 memorized. No, it's okay. Is there a understood 00:33:15.680 --> 00:33:20.480 mechanism for why that's the case? Yes. So there's 00:33:20.480 --> 00:33:23.140 actually two different mechanisms. One is called 00:33:23.140 --> 00:33:26.240 phototoxic and the other is called photoallergic, 00:33:26.259 --> 00:33:28.980 which is less common. So the most common one 00:33:28.980 --> 00:33:32.339 is phototoxic. It's not an immunologic immune. 00:33:32.720 --> 00:33:35.900 system type response. And it happens because 00:33:35.900 --> 00:33:40.859 there's an increase that the UVA light reacts 00:33:40.859 --> 00:33:45.220 with certain medications within the skin. And 00:33:45.220 --> 00:33:47.759 so that increases then the skin sensitivity to 00:33:47.759 --> 00:33:51.180 sunburn. Okay. So when you take a drug, some 00:33:51.180 --> 00:33:53.420 of that drug, because it just goes everywhere. 00:33:53.500 --> 00:33:55.480 Right. And some of it, because it's carried by 00:33:55.480 --> 00:33:58.059 the blood. Right. Will get into your skin. And 00:33:58.059 --> 00:34:01.740 because the light interacts with that. drug or 00:34:01.740 --> 00:34:04.480 the metabolite or how the drug is broken down 00:34:04.480 --> 00:34:09.000 it will basically the sun changes its shape because 00:34:09.000 --> 00:34:10.900 of the energy of the sun. And then that will 00:34:10.900 --> 00:34:13.300 basically cause it to be somewhat toxic. Right. 00:34:13.420 --> 00:34:15.400 Okay. That's really interesting. And I know I 00:34:15.400 --> 00:34:16.880 thought it was really interesting. And it's also, 00:34:16.960 --> 00:34:21.219 it's concentration dependent. So that means that 00:34:21.219 --> 00:34:24.619 if we were all able to get the same concentration 00:34:24.619 --> 00:34:28.079 of the drug in our skin, then we'd all have the 00:34:28.079 --> 00:34:30.860 problem. But more, some people are just more 00:34:30.860 --> 00:34:33.699 sensitive to that than others. Gotcha. So some 00:34:33.699 --> 00:34:35.579 people have receptors in their body that are 00:34:35.579 --> 00:34:38.360 more sensitive to that. toxic metabolite from 00:34:38.360 --> 00:34:40.619 the sun, from these certain types of drugs. Or 00:34:40.619 --> 00:34:42.599 maybe they just, for whatever reason, the way 00:34:42.599 --> 00:34:46.300 their body has broken down the drug, it goes 00:34:46.300 --> 00:34:49.099 into their skin more than others and stuff. And 00:34:49.099 --> 00:34:52.019 so then the, then the UVA light is going to interact 00:34:52.019 --> 00:34:54.719 with it more, more commonly. Yeah. That is so 00:34:54.719 --> 00:34:58.280 interesting. That makes me think that, man, we 00:34:58.280 --> 00:35:00.079 could go down a rabbit hole on this, but like, 00:35:00.099 --> 00:35:02.179 you know, there are just certain days where you 00:35:02.179 --> 00:35:04.949 feel bad. or you feel good and you really don't 00:35:04.949 --> 00:35:06.849 know why. And I wonder if it's because like, 00:35:06.849 --> 00:35:08.650 well, I ate that pizza pizza last night and it 00:35:08.650 --> 00:35:10.889 got into my skin and the sun is interacting with 00:35:10.889 --> 00:35:16.070 it. It's amazing how many things, yeah, how variable 00:35:16.070 --> 00:35:18.909 human beings are. That's pretty incredible that, 00:35:18.929 --> 00:35:20.809 yeah, you would take something, it gets into 00:35:20.809 --> 00:35:24.289 your skin and then you could potentially feel 00:35:24.289 --> 00:35:27.590 sick from that. It's so interesting. So, okay. 00:35:27.650 --> 00:35:30.230 We've talked a lot about kind of, you know, why 00:35:30.230 --> 00:35:34.030 on earth we, you know, get sunburn and kind of, 00:35:34.030 --> 00:35:37.789 we've kind of, kind of, kind of touched a little 00:35:37.789 --> 00:35:39.550 bit about what to do about it, but let's really 00:35:39.550 --> 00:35:42.250 now talk about what to do about it. And again, 00:35:42.349 --> 00:35:45.010 like Josh talked about avoiding sun exposure, 00:35:45.170 --> 00:35:48.989 if you can, is a good idea. And especially between 00:35:48.989 --> 00:35:55.750 10 AM and 4 PM, because that is when, um, I believe 00:35:55.750 --> 00:36:01.659 it's UV. the UVA and UVB lights are the most 00:36:01.659 --> 00:36:06.539 potent. And so that between 10 and 4, you'd like 00:36:06.539 --> 00:36:09.960 to stay away from the outside or be protected 00:36:09.960 --> 00:36:15.079 as much as possible. Wearing protective clothing 00:36:15.079 --> 00:36:17.880 like wide brimmed hats or long sleeve shirts 00:36:17.880 --> 00:36:20.800 or wearing sunglasses. Remember, I talked about 00:36:20.800 --> 00:36:23.199 the fact that you can also get cataracts from 00:36:23.199 --> 00:36:25.719 being exposed long term to the sun. And again, 00:36:25.780 --> 00:36:28.900 it's because the UVA and UVB light can get into 00:36:28.900 --> 00:36:33.440 the cells in your eye. And it's beyond the scope 00:36:33.440 --> 00:36:35.579 for us to talk about it, you know, here and stuff. 00:36:35.599 --> 00:36:38.079 But it can cause sun damage to your eyes as well, 00:36:38.079 --> 00:36:40.599 too. It takes time for that to happen as well. 00:36:41.500 --> 00:36:44.460 Um, and then, um, the other thing, the next thing 00:36:44.460 --> 00:36:47.400 you want to think about is you don't go to a 00:36:47.400 --> 00:36:51.139 tanning salon. Tanning salons actually have more 00:36:51.139 --> 00:36:54.940 UVA and UVB light put out than the sun itself. 00:36:55.039 --> 00:36:57.719 So they can be more damaging over time. Well, 00:36:57.719 --> 00:36:59.300 it's also, it's just more concentrated because 00:36:59.300 --> 00:37:01.280 you're literally right there at the source, right? 00:37:01.320 --> 00:37:04.019 Because you know, this. Obviously the sun is 00:37:04.019 --> 00:37:07.260 huge, but it's 93 million miles away. And some 00:37:07.260 --> 00:37:09.219 of that is just, and it's also the earth is a 00:37:09.219 --> 00:37:11.019 huge place. So a lot of that's just going to 00:37:11.019 --> 00:37:13.099 get spread out to different places. Right. You're 00:37:13.099 --> 00:37:16.199 literally there in the bed. Right. So not a good 00:37:16.199 --> 00:37:18.940 idea to do that. And then if you can stay in 00:37:18.940 --> 00:37:21.559 the shade, you know, when you're outside as much 00:37:21.559 --> 00:37:23.280 as possible, that's also going to help. It's 00:37:23.280 --> 00:37:24.980 funny because I actually read that the shade 00:37:24.980 --> 00:37:29.300 isn't as protective as people think. The shade 00:37:29.300 --> 00:37:34.159 will protect you from the heat. Because the heat 00:37:34.159 --> 00:37:36.619 from the sun is not due to the visible light 00:37:36.619 --> 00:37:38.400 of the sun. It's actually due to its infrared 00:37:38.400 --> 00:37:42.460 rays, which are invisible rays that have a longer 00:37:42.460 --> 00:37:47.880 wavelength than visible light. And that is where 00:37:47.880 --> 00:37:49.780 the heat comes from. So a lot of times you are 00:37:49.780 --> 00:37:51.539 in the shade, you're like, oh, I feel so much 00:37:51.539 --> 00:37:53.940 less hot. But actually the UV rays are actually 00:37:53.940 --> 00:37:56.400 still getting through. So even in the shade, 00:37:56.599 --> 00:37:59.829 it's... still good to apply sunscreen, especially 00:37:59.829 --> 00:38:02.869 if the UV index is still fairly high. Right. 00:38:02.949 --> 00:38:04.889 And I think that what I'm saying, and I think 00:38:04.889 --> 00:38:06.989 what Josh is alluding to as well too, is that 00:38:06.989 --> 00:38:11.949 there's not just one thing to do to. mitigate 00:38:11.949 --> 00:38:17.630 these um photo aging type um exposures but there's 00:38:17.630 --> 00:38:19.949 there's several things that you can do concurrently 00:38:19.949 --> 00:38:22.510 at the same time um to help protect yourself 00:38:22.510 --> 00:38:26.329 um and and and your kiddos too if you're a parent 00:38:26.329 --> 00:38:29.449 you know and stuff so yeah and i yeah especially 00:38:29.449 --> 00:38:34.239 with the kiddos too like the incidents of melanomas 00:38:34.239 --> 00:38:37.699 or carcinomas in kids is relatively low, almost 00:38:37.699 --> 00:38:40.199 non -existent, mainly for the reasons that we 00:38:40.199 --> 00:38:44.400 talked about is that cancers usually happen over 00:38:44.400 --> 00:38:47.320 a long period of time. It's like if any of you 00:38:47.320 --> 00:38:50.500 own a car, if you hear that sound in your car 00:38:50.500 --> 00:38:54.039 and you ignore it for the next five to 10 months, 00:38:54.480 --> 00:38:58.380 then whatever the wear and tear that's happening 00:38:58.380 --> 00:39:00.420 in your car is going to build up. And over time, 00:39:00.639 --> 00:39:05.480 it could potentially snap. either transmission 00:39:05.480 --> 00:39:07.940 lines or whatever you're essentially talking 00:39:07.940 --> 00:39:14.400 about in your car. And the same thing happens 00:39:14.400 --> 00:39:17.940 in your body. Essentially, anytime that you go 00:39:17.940 --> 00:39:21.519 anywhere or do anything, you are accumulating 00:39:21.519 --> 00:39:25.719 certain types of damage in your body. And your 00:39:25.719 --> 00:39:27.380 body's quite good at repairing a lot of that 00:39:27.380 --> 00:39:30.760 damage. But if it can't keep up with the repair 00:39:30.760 --> 00:39:35.829 to damage ratio, um is imbalanced then yeah that's 00:39:35.829 --> 00:39:38.210 going to accumulate over time and there are things 00:39:38.210 --> 00:39:40.329 that you can do like mom said to mitigate that 00:39:40.329 --> 00:39:44.250 amount of damage but it's also not it's not fail 00:39:44.250 --> 00:39:47.449 safe you know you could do everything right put 00:39:47.449 --> 00:39:49.489 on all the sunscreen wear all the long clothes 00:39:49.489 --> 00:39:52.449 and you could still get a melanoma or carcinoma 00:39:52.449 --> 00:39:54.849 just because just like someone who maybe smokes 00:39:54.849 --> 00:39:57.210 one cigarette or even is around secondhand smoke 00:39:57.210 --> 00:40:00.429 can still develop some type of lung cancer so 00:40:00.880 --> 00:40:02.860 A lot of these aren't guarantees. They're just 00:40:02.860 --> 00:40:09.099 ways to tampen down the risk. Great. As far as 00:40:09.099 --> 00:40:13.019 sunscreen is concerned, only sunscreens with 00:40:13.019 --> 00:40:17.409 a sun protection factor of 15 or greater. have 00:40:17.409 --> 00:40:20.690 been shown along, if you use them with the other 00:40:20.690 --> 00:40:23.530 protection factors, those are the ones that can 00:40:23.530 --> 00:40:26.510 reduce the risk of skin cancer and premature 00:40:26.510 --> 00:40:30.090 aging. But if you have a, and I don't know that 00:40:30.090 --> 00:40:32.789 I've really, well, yeah, I mean, in the old days, 00:40:32.869 --> 00:40:36.349 like baby oil, you know, or Hawaiian Tropic with 00:40:36.349 --> 00:40:38.940 nothing in it, that would definitely not. protect 00:40:38.940 --> 00:40:41.400 you at all. So anything with a sunscreen with 00:40:41.400 --> 00:40:45.380 a value of two to 14 may only mitigate sunburn, 00:40:45.619 --> 00:40:47.460 but it's not going to have any effect on skin 00:40:47.460 --> 00:40:50.360 cancer or premature aging. Yeah. And sunscreen, 00:40:50.480 --> 00:40:52.860 remember the SPF factor really just correlates 00:40:52.860 --> 00:40:56.380 or corresponds to your sunburn, your ability 00:40:56.380 --> 00:40:59.519 to burn. So it's actually quite a bit of bonus 00:40:59.519 --> 00:41:04.420 that you get to diminish your risk of skin cancers 00:41:04.420 --> 00:41:06.300 as well, because they're, they're caused by the 00:41:06.300 --> 00:41:08.980 same thing, which is UV light that you, uh, sunburn 00:41:08.980 --> 00:41:11.440 they're caused by the same thing, but they have 00:41:11.440 --> 00:41:14.400 a different mechanism of how the damages accrued. 00:41:14.400 --> 00:41:17.920 Yes. Um, another interesting thing about sunscreen 00:41:17.920 --> 00:41:22.420 itself is a, is a, is a word called substantivity. 00:41:22.699 --> 00:41:28.340 Um, um, and so, um, it's spelled S U B S T A 00:41:28.340 --> 00:41:34.579 N T I V I T Y. And what that means is it's how 00:41:34.579 --> 00:41:40.760 well does the substance stick to your skin? So 00:41:40.760 --> 00:41:43.469 that's going to be. It's going to determine how 00:41:43.469 --> 00:41:45.809 well the sunscreen will or how effective the 00:41:45.809 --> 00:41:48.389 sunscreen will be long term. And either if you've 00:41:48.389 --> 00:41:51.530 got prolonged exercising, swimming or just sweating 00:41:51.530 --> 00:41:55.650 in general. So and those those products that 00:41:55.650 --> 00:41:58.909 are more cream based. So they're kind of a water 00:41:58.909 --> 00:42:02.630 and oil, you know, kind of as a base are going 00:42:02.630 --> 00:42:05.010 to be better at staying on your skin than something 00:42:05.010 --> 00:42:08.010 that has an alcohol base because alcohol evaporates 00:42:08.010 --> 00:42:10.610 a lot faster. That's a really good point. I think 00:42:10.610 --> 00:42:13.360 getting into. this is a really good topic to 00:42:13.360 --> 00:42:16.400 get into what sunscreen is and how it should 00:42:16.400 --> 00:42:20.500 be applied and why do we apply it? So like mom 00:42:20.500 --> 00:42:23.239 said, go ahead. I've got one more point before 00:42:23.239 --> 00:42:26.300 you dive into that. So with this, with this, 00:42:26.300 --> 00:42:29.280 you know, thing about this substantivity and 00:42:29.280 --> 00:42:32.340 I'm, I'm thinking, I'm thinking I, I put sunscreen 00:42:32.340 --> 00:42:34.400 on my kids, you know, and stuff, but just never 00:42:34.400 --> 00:42:38.440 knew enough about it. So when you look at. at 00:42:38.440 --> 00:42:40.980 sunscreens, it will tell you whether or not it's 00:42:40.980 --> 00:42:44.139 water resistant or not. And it has to do with 00:42:44.139 --> 00:42:48.619 this substantivity ability. And it will tell 00:42:48.619 --> 00:42:52.280 you it's either it is water resistant for 40 00:42:52.280 --> 00:42:56.349 or 80 minutes. And so sure enough, when you look 00:42:56.349 --> 00:42:59.389 at sunscreens in the grocery store or at Walmart 00:42:59.389 --> 00:43:02.789 or whatever, you definitely see that it says 00:43:02.789 --> 00:43:05.150 that on the bottle. And so again, then you're 00:43:05.150 --> 00:43:07.690 going to want to use that guide as to how frequently 00:43:07.690 --> 00:43:10.489 you reapply it because it's only going to be 00:43:10.489 --> 00:43:13.349 water resistant for 40 or 80 minutes. And we'll 00:43:13.349 --> 00:43:16.309 talk about reapplication in just a minute. Yeah. 00:43:16.349 --> 00:43:18.610 And by water resistant, do you just mean that 00:43:18.610 --> 00:43:20.869 it's going to start becoming water soluble and 00:43:20.869 --> 00:43:22.989 it'll just get into the water and wash off? And 00:43:22.989 --> 00:43:24.530 then you're going to be at greater risk of getting 00:43:24.530 --> 00:43:28.690 sunburn and the sun effects. Gotcha. Okay. Yeah. 00:43:29.050 --> 00:43:32.769 When sunscreen, a lot of them basically have 00:43:32.769 --> 00:43:35.269 this kind of, except for the sprays, a lot of 00:43:35.269 --> 00:43:39.230 them have this lotion -like consistency to them. 00:43:39.739 --> 00:43:41.639 But if you look at the inactive, let's just take 00:43:41.639 --> 00:43:43.920 a look at some of the ingredients in sunscreen 00:43:43.920 --> 00:43:46.260 and we can talk about, you know. I can do that 00:43:46.260 --> 00:43:48.760 now if you'd like. Yeah, please. All right. Yeah. 00:43:48.800 --> 00:43:51.039 So we, I think people are probably wondering 00:43:51.039 --> 00:43:52.960 is like, all right, sunscreen's great, but how 00:43:52.960 --> 00:43:55.579 does it work and what is inside of it that is 00:43:55.579 --> 00:43:57.900 going to allow it to block out these UV rays? 00:43:58.119 --> 00:44:01.119 So we have two basic types of sunscreens. They're 00:44:01.119 --> 00:44:03.940 either a chemical sunscreen or what they call 00:44:03.940 --> 00:44:06.940 a physical sunscreen. And a chemical sunscreen 00:44:06.940 --> 00:44:15.559 absorbs and blocks UV radiation transmission 00:44:15.559 --> 00:44:18.800 to the skin epidermis, so that top layer. So 00:44:18.800 --> 00:44:22.099 it absorbs it and blocks it from having an effect 00:44:22.099 --> 00:44:26.599 on the epidermis. And it will absorb at least 00:44:26.599 --> 00:44:33.539 85 % of UV radiation at the most UVA, UVB light. 00:44:33.920 --> 00:44:38.079 you know, and stuff. So, um, and there are 12 00:44:38.079 --> 00:44:43.219 common sunscreen agents in, um, OTC over the 00:44:43.219 --> 00:44:45.539 counter sunscreen products that fall into this 00:44:45.539 --> 00:44:50.159 category. Interestingly. These products, although 00:44:50.159 --> 00:44:52.139 they're available because they're over -the -counter 00:44:52.139 --> 00:44:55.079 and they're in my sunscreen at home, they have 00:44:55.079 --> 00:44:58.699 not been formally evaluated for safety and efficacy. 00:44:59.019 --> 00:45:01.400 The studies just haven't been done. Again, because 00:45:01.400 --> 00:45:03.480 these products have been around for a while, 00:45:03.599 --> 00:45:05.840 and then there's been some concern about, oh, 00:45:05.840 --> 00:45:07.960 I wonder if it's really safe and effective. So 00:45:07.960 --> 00:45:10.039 some of that has not been done for these yet. 00:45:10.059 --> 00:45:11.900 It doesn't mean you're going to die because you're 00:45:11.900 --> 00:45:15.119 using them and stuff, but there is a lack of 00:45:15.119 --> 00:45:19.019 information about them. And there's one point, 00:45:19.119 --> 00:45:21.900 there's been a couple of studies that have shown 00:45:21.900 --> 00:45:25.880 actually some systemic absorption of some of 00:45:25.880 --> 00:45:29.159 these chemicals into the bloodstream. We don't 00:45:29.159 --> 00:45:30.900 know how to interpret that. And so without a 00:45:30.900 --> 00:45:33.199 study, you don't know how to be alarmed about 00:45:33.199 --> 00:45:35.579 it or not. Well, yeah, actually speaking of that 00:45:35.579 --> 00:45:38.519 study, that study was conducted by the FDA and 00:45:38.519 --> 00:45:41.059 how they found out the absorption into the bloodstream. 00:45:41.719 --> 00:45:44.579 Um, the dose that was applied to these individuals 00:45:44.579 --> 00:45:47.679 to get it into the bloodstream was two bottles 00:45:47.679 --> 00:45:51.380 of sunscreen over a four day period. Whoa. Okay. 00:45:51.460 --> 00:45:54.400 Now most people on average use one bottle of 00:45:54.400 --> 00:45:57.239 sunscreen a year. Yes. Um, most people are not 00:45:57.239 --> 00:45:58.760 very liberal with their sunscreen cause it just 00:45:58.760 --> 00:46:00.840 doesn't feel very, it, you know, you, you feel 00:46:00.840 --> 00:46:03.079 a bit greasy. You feel like, you know, like a 00:46:03.079 --> 00:46:08.099 buttered chicken. Um, but so don't you love his, 00:46:08.099 --> 00:46:13.949 don't you love his, his, just his images. But 00:46:13.949 --> 00:46:18.769 I think a lot of times with stuff like that, 00:46:18.809 --> 00:46:21.010 like dose response is important. I remember there 00:46:21.010 --> 00:46:23.449 was a time when people were saying that Diet 00:46:23.449 --> 00:46:26.869 Coke caused cancer because there was a study 00:46:26.869 --> 00:46:29.670 that was done in rats where they gave them an 00:46:29.670 --> 00:46:33.750 inordinate amount of, what's the? Aspartame. 00:46:33.809 --> 00:46:36.329 Yeah, aspartame, which is the sweetener, artificial 00:46:36.329 --> 00:46:38.849 sweetener. But they gave it to rats at this absurd 00:46:38.849 --> 00:46:41.500 level that would never be given. Unless you're 00:46:41.500 --> 00:46:45.460 crazy drinking Diet Coke like my mom. She would 00:46:45.460 --> 00:46:49.139 have loved that study. Sometimes you have to 00:46:49.139 --> 00:46:51.539 take a lot of this with a grain of salt. That's 00:46:51.539 --> 00:46:53.679 a great point, Josh. A grain of sunscreen. Because 00:46:53.679 --> 00:46:57.389 yes, it is possible. But on some other planet 00:46:57.389 --> 00:46:59.929 where you would have to apply two bottles of 00:46:59.929 --> 00:47:02.030 sunscreen every week in order to survive. And 00:47:02.030 --> 00:47:03.710 that might be Venus. Thanks for sharing that 00:47:03.710 --> 00:47:08.670 with us. The other type of sunscreen is called 00:47:08.670 --> 00:47:11.929 a physical sunscreen. And these ingredients have 00:47:11.929 --> 00:47:14.769 been identified as safe and effective by the 00:47:14.769 --> 00:47:18.030 Food and Drug Administration. And these are those 00:47:18.030 --> 00:47:21.420 sunscreens that have kind of that opaque. opaque 00:47:21.420 --> 00:47:24.099 or kind of cloudy kind of appearance. And it's 00:47:24.099 --> 00:47:28.719 your zinc oxide and your titanium dioxide. And 00:47:28.719 --> 00:47:32.239 so instead of absorbing ultraviolet radiation, 00:47:32.579 --> 00:47:38.239 they reflect it and scatter it away. And so So 00:47:38.239 --> 00:47:42.860 it, you know, the older, when I was, when I was 00:47:42.860 --> 00:47:44.579 a kid growing up, I would just get a tube of 00:47:44.579 --> 00:47:46.599 zinc oxide, like, you know, it's like desiccant, 00:47:46.599 --> 00:47:49.340 like diaper ointment, just pour it over my nose. 00:47:49.420 --> 00:47:51.860 And it was, I had a white nose, you know, and 00:47:51.860 --> 00:47:54.320 stuff, but it was, it blocked the sun from my 00:47:54.320 --> 00:47:58.219 skin. Now these ingredients are more, they've 00:47:58.219 --> 00:48:00.599 got some ingredients added to these sunscreens 00:48:00.599 --> 00:48:03.000 that are more translucent or they're more like 00:48:03.000 --> 00:48:05.719 see -through and stuff. So it makes it so, I 00:48:05.719 --> 00:48:07.920 mean, I actually have a bottle for. my grandkids. 00:48:08.179 --> 00:48:12.159 And it's got zinc oxide in it, but you can actually, 00:48:12.219 --> 00:48:14.820 it comes off kind of white, but you can actually 00:48:14.820 --> 00:48:17.880 rub it in now and then you don't see it anymore. 00:48:18.000 --> 00:48:20.559 So it's not as like, I've got sunscreen all over 00:48:20.559 --> 00:48:23.559 my body. And again, it's got this mechanism of 00:48:23.559 --> 00:48:27.300 being, you know, it deflects the sun rather than 00:48:27.300 --> 00:48:31.179 absorbing it into your skin. Yeah, that's really 00:48:31.179 --> 00:48:35.500 good. And yes, you might also hear these as organic 00:48:35.500 --> 00:48:38.320 or inorganic, where one is containing carbon, 00:48:38.460 --> 00:48:41.400 they're biological molecules, or inorganic, things 00:48:41.400 --> 00:48:45.659 like zinc and titanium. These are just metals 00:48:45.659 --> 00:48:48.840 that have bonded with oxygen. And I know there 00:48:48.840 --> 00:48:51.420 is some concern with zinc oxide and titanium 00:48:51.420 --> 00:48:55.179 oxide because the technology now of actually 00:48:55.179 --> 00:48:57.119 getting them to be a little bit more transparent 00:48:57.119 --> 00:48:59.750 and fine is that they actually are... They're 00:48:59.750 --> 00:49:02.510 coated in nanoparticles, so essentially they're 00:49:02.510 --> 00:49:05.989 very, very tiny. There is this concern that these 00:49:05.989 --> 00:49:09.510 particles are small enough to not just be able 00:49:09.510 --> 00:49:11.750 to be translucent and get on the skin, but actually 00:49:11.750 --> 00:49:15.590 be better at getting into your bloodstream. Dioxides 00:49:15.590 --> 00:49:18.849 actually can cross the blood -brain barrier and 00:49:18.849 --> 00:49:22.570 actually can do some damage to neurons. That 00:49:22.570 --> 00:49:25.489 is just speculative at this moment. It seems 00:49:25.489 --> 00:49:27.469 more theoretical and some studies would need 00:49:27.469 --> 00:49:31.260 to be done. There are sunscreens out there that 00:49:31.260 --> 00:49:34.320 are non -nanoparticle base and you can get zinc 00:49:34.320 --> 00:49:37.000 or titanium oxides that don't have this nanoparticle 00:49:37.000 --> 00:49:39.420 technology. It might not be a good feel. Like 00:49:39.420 --> 00:49:41.460 when you're rubbing it on, it might not be as 00:49:41.460 --> 00:49:45.360 basically as a pleasant of an application experience 00:49:45.360 --> 00:49:47.460 as these nanoparticles as that's what they were 00:49:47.460 --> 00:49:50.099 designed to do is basically help spread and absorb 00:49:50.099 --> 00:49:54.079 a little bit is into your skin. But there might 00:49:54.079 --> 00:49:56.199 be this, you know, that's the thing is like when 00:49:56.199 --> 00:49:58.719 you're using new technology. You kind of are 00:49:58.719 --> 00:50:01.579 the guinea pig and you're figuring out if there 00:50:01.579 --> 00:50:03.619 are risks associated with this new technology. 00:50:03.760 --> 00:50:06.880 So you're just going to have to take a bet because 00:50:06.880 --> 00:50:09.460 there's no evidence one way or the other. It 00:50:09.460 --> 00:50:12.300 could just be that speculation on this or it 00:50:12.300 --> 00:50:15.059 could be nothing. So I just wanted to put that 00:50:15.059 --> 00:50:18.750 out there as well. Thanks. Of course. A couple 00:50:18.750 --> 00:50:21.789 of last areas to talk about before we wrap up 00:50:21.789 --> 00:50:25.469 today. First is dosing or administering sunscreen. 00:50:25.789 --> 00:50:28.889 And so the recommendation is actually a whole 00:50:28.889 --> 00:50:33.130 ounce of sunscreen. But it's broken up. It's 00:50:33.130 --> 00:50:35.210 not like a whole ounce like on your leg, but 00:50:35.210 --> 00:50:38.250 it's like a teaspoon per leg and a half a teaspoon 00:50:38.250 --> 00:50:41.530 per arm, a half a teaspoon for your face. And 00:50:41.530 --> 00:50:43.849 you may end up kind of doing that, you know, 00:50:43.849 --> 00:50:47.500 and stuff. But just... But realize that you've 00:50:47.500 --> 00:50:51.099 got to put on a sufficient amount for it to do 00:50:51.099 --> 00:50:55.199 the work that it's intended to do. And then you 00:50:55.199 --> 00:50:58.980 also want to apply it 15 to 30 minutes before 00:50:58.980 --> 00:51:02.280 you're going to be exposed to the sun and reapply 00:51:02.280 --> 00:51:06.420 it every two hours unless you get exposed to 00:51:06.420 --> 00:51:08.980 water or excessive sweating or you dry yourself 00:51:08.980 --> 00:51:11.699 off with a towel. Any of those then will require 00:51:11.699 --> 00:51:15.360 you to reapply the sunscreen again. So to keep 00:51:15.360 --> 00:51:18.780 it, you know, you know, working and stuff. As 00:51:18.780 --> 00:51:20.500 far as a couple of special, was there something 00:51:20.500 --> 00:51:22.440 you wanted to add to that, Josh, before I move 00:51:22.440 --> 00:51:24.739 on? I just wanted to say, yeah, because the, 00:51:24.840 --> 00:51:27.780 when you're, you want to think about sunscreen 00:51:27.780 --> 00:51:30.179 almost as like a thin layer of paint. Like when 00:51:30.179 --> 00:51:33.179 you're painting the room, it's the, the paint 00:51:33.179 --> 00:51:35.500 isn't getting absorbed into the walls. It's basically 00:51:35.500 --> 00:51:39.500 just covering the surface of the wall. And you, 00:51:39.780 --> 00:51:42.360 because. That makes sense because you want to 00:51:42.360 --> 00:51:44.880 limit the amount of UV light getting to your 00:51:44.880 --> 00:51:47.320 skin. So what you want to do is you want to coat 00:51:47.320 --> 00:51:49.940 that on. You want to let it dry because it basically 00:51:49.940 --> 00:51:52.739 forms that kind of extra layer on the outside 00:51:52.739 --> 00:51:56.460 of your skin. And then that is going to provide 00:51:56.460 --> 00:51:58.760 that protective benefit. And being in Texas and 00:51:58.760 --> 00:52:00.900 also being myself, I know I'm going to sweat. 00:52:01.300 --> 00:52:04.079 And it's very hard to reapply sunscreen once 00:52:04.079 --> 00:52:06.539 you're sweaty because sunscreen, by definition, 00:52:07.050 --> 00:52:09.230 doesn't mix with water very well right so you 00:52:09.230 --> 00:52:11.250 have to dry yourself off to put the sunscreen 00:52:11.250 --> 00:52:13.309 back yeah you but at the same time you might 00:52:13.309 --> 00:52:15.869 just get that early benefit prior to sweating 00:52:15.869 --> 00:52:19.349 um and and that's still better than nothing uh 00:52:19.349 --> 00:52:23.199 but you know Right. But that whole reapplication 00:52:23.199 --> 00:52:26.079 thing, and he's still young and he doesn't know 00:52:26.079 --> 00:52:28.340 what it's like really to get premature aging 00:52:28.340 --> 00:52:31.639 or be at risk for skin cancer. So again, he probably 00:52:31.639 --> 00:52:34.380 should still reapply that even if he does sweat. 00:52:34.440 --> 00:52:36.599 That's true. But it's like, imagine, but you 00:52:36.599 --> 00:52:39.280 have to imagine that practically because being 00:52:39.280 --> 00:52:41.900 in like, I play soccer every week. And so like, 00:52:41.920 --> 00:52:44.630 if I went out and played soccer. I'm going to 00:52:44.630 --> 00:52:46.389 sweat in the first five minutes. Yeah. So you're 00:52:46.389 --> 00:52:48.789 like, hold on guys, just a second. And then by 00:52:48.789 --> 00:52:50.590 putting it on and they go back out again, hold 00:52:50.590 --> 00:52:53.130 on, I got to do it again. So at some point it's 00:52:53.130 --> 00:52:56.369 just not realistic to reapply. I think if you're 00:52:56.369 --> 00:52:59.570 in a place, I think if you're in a place where 00:52:59.570 --> 00:53:02.570 it's just really bright and sunny, but it's not 00:53:02.570 --> 00:53:04.269 very hot outside. And I've definitely been to 00:53:04.269 --> 00:53:06.349 some of those places where I'm like, I'm not 00:53:06.349 --> 00:53:08.650 sweating, but it's the sun is really intense 00:53:08.650 --> 00:53:11.130 right now. The UV index might be, you know, nine 00:53:11.130 --> 00:53:13.960 to 12 or something like that. then I think that's 00:53:13.960 --> 00:53:17.840 when it's really good to reapply it. But I think 00:53:17.840 --> 00:53:19.860 when you're in a place like Texas, it's going 00:53:19.860 --> 00:53:22.860 to be really hard to do that. And it's probably 00:53:22.860 --> 00:53:25.570 better just to wear clothing that can... block 00:53:25.570 --> 00:53:28.650 you from the sun. Right. And Josh has mentioned 00:53:28.650 --> 00:53:31.170 the ultraviolet index a couple of times. Let 00:53:31.170 --> 00:53:32.929 me just tell you what that is really quickly. 00:53:33.510 --> 00:53:36.670 It was a number or an index that was created 00:53:36.670 --> 00:53:40.010 by the Environmental Protection Agency in the 00:53:40.010 --> 00:53:43.250 United States. And what it does is that it rates 00:53:43.250 --> 00:53:46.969 the amount of ultraviolet radiation that reaches 00:53:46.969 --> 00:53:52.050 the Earth's surface at a specific time at a specific 00:53:52.050 --> 00:53:56.739 location. And the time of day, the season, altitude, 00:53:57.019 --> 00:54:00.320 as well as land cover all affect this index. 00:54:00.699 --> 00:54:04.539 And as the rate increases, then your exposure 00:54:04.539 --> 00:54:07.659 risk increases. And so there's actually a table 00:54:07.659 --> 00:54:09.900 that tells you whether or not you're at low, 00:54:09.960 --> 00:54:14.239 medium, or very high risk for being exposed to 00:54:14.239 --> 00:54:18.059 UV light. So just a little aside there. Yeah, 00:54:18.079 --> 00:54:20.059 that's a good point. I think also people's intuition 00:54:20.059 --> 00:54:23.079 doesn't go along with the UV index. Like the 00:54:23.079 --> 00:54:25.679 hottest part of the day is usually around three 00:54:25.679 --> 00:54:28.300 or four in the afternoon. But actually the time 00:54:28.300 --> 00:54:30.320 that the UV index is usually the highest is around 00:54:30.320 --> 00:54:33.280 noon because the sun is usually directly above 00:54:33.280 --> 00:54:36.440 you. And so it's sending as many rays as it can. 00:54:36.860 --> 00:54:39.780 So sometimes UV correlates with the hottest part 00:54:39.780 --> 00:54:43.150 of the day, but sometimes it doesn't. And usually 00:54:43.150 --> 00:54:47.030 heat is infrared rays instead of UV rays, which 00:54:47.030 --> 00:54:49.309 causes that premature aging and sunburn and stuff. 00:54:49.570 --> 00:54:52.409 Excellent. So let's talk about a couple of special 00:54:52.409 --> 00:54:56.269 populations and application of sunscreen. Children 00:54:56.269 --> 00:55:01.059 are our first category. Children less than six 00:55:01.059 --> 00:55:03.679 months of age, little babies, they really should 00:55:03.679 --> 00:55:06.699 not be exposed to the sun. You want to keep them 00:55:06.699 --> 00:55:09.980 shaded or covered up as much as possible. And 00:55:09.980 --> 00:55:12.880 applying sunscreen to them is also, that would 00:55:12.880 --> 00:55:16.860 be up to your pediatrician because their skin 00:55:16.860 --> 00:55:23.400 is so new and it's so... absorbable that, um, 00:55:23.500 --> 00:55:26.800 applying a sunscreen, there might be some absorption 00:55:26.800 --> 00:55:28.840 that you don't want for your kiddo. And again, 00:55:28.900 --> 00:55:30.960 but just because we don't know that would be 00:55:30.960 --> 00:55:33.460 a conversation that you'd have with your pediatrician. 00:55:33.460 --> 00:55:35.480 So again, it's just keep them out of the sun 00:55:35.480 --> 00:55:38.119 as much as possible. Keep them covered up. If 00:55:38.119 --> 00:55:40.019 they are in the sun, we all like to take our 00:55:40.019 --> 00:55:42.280 little babies in the pool and that's fine, you 00:55:42.280 --> 00:55:43.880 know, and stuff and all, but just be wise as 00:55:43.880 --> 00:55:45.199 you do that. Yeah. If they're out there for a 00:55:45.199 --> 00:55:47.619 long time, maybe just put a little sun hat on 00:55:47.619 --> 00:55:50.440 them. Right. Um, you know, Floaties, you know, 00:55:50.440 --> 00:55:52.219 so that their whole body's covered up. Keep them 00:55:52.219 --> 00:55:55.179 in the shade. Yeah. I think because you're really 00:55:55.179 --> 00:55:57.739 trying to prevent them from burning rather than 00:55:57.739 --> 00:55:59.820 skin cancer and aging. I mean, that's going to 00:55:59.820 --> 00:56:01.159 happen. Although you are really, ultimately, 00:56:01.340 --> 00:56:03.199 Josh, actually, you really are trying to keep 00:56:03.199 --> 00:56:05.639 them from skin cancer and aging because that's 00:56:05.639 --> 00:56:08.480 a, remember, it's a long -term process. And the 00:56:08.480 --> 00:56:11.059 more we protect our kiddos at their earlier age, 00:56:11.239 --> 00:56:13.920 the better they'll be protected long -term. True. 00:56:13.940 --> 00:56:15.760 But you also, like you said, with the absorption 00:56:15.760 --> 00:56:18.440 thing, you don't. Yeah. It's like, you're, uh, 00:56:18.659 --> 00:56:21.380 you're just like mitigating a good, different 00:56:21.380 --> 00:56:23.760 risk at different times. You're right. But you're 00:56:23.760 --> 00:56:25.519 right. I mean, at the end of the age, you're 00:56:25.519 --> 00:56:27.619 the parent and you have the choice to do what 00:56:27.619 --> 00:56:29.400 you want for your kid, you know? So you're right. 00:56:29.460 --> 00:56:30.760 And like, you wouldn't want to give your kid 00:56:30.760 --> 00:56:33.500 a cigarette at one, you know, because that's 00:56:33.500 --> 00:56:35.460 going to only set them up for potential lung 00:56:35.460 --> 00:56:39.260 cancer earlier on. Um, yeah. So it's all about 00:56:39.260 --> 00:56:41.800 that, um, you know, different risks at different 00:56:41.800 --> 00:56:43.980 times of life. Right. And then kiddos over six 00:56:43.980 --> 00:56:45.639 months of age, you definitely want to use sunscreen. 00:56:46.119 --> 00:56:49.780 And I would recommend those sunscreens that are 00:56:49.780 --> 00:56:52.199 more water resistant, you know, that have that 00:56:52.199 --> 00:56:55.179 greater substantivity. And you want to use at 00:56:55.179 --> 00:56:58.539 least a sun protection factor of 15 or greater 00:56:58.539 --> 00:57:02.519 and stuff. So you want to reduce their skin cancer 00:57:02.519 --> 00:57:06.059 chances. The other category of special populations 00:57:06.059 --> 00:57:09.500 is pregnant and lactating women. Lactating meaning 00:57:09.500 --> 00:57:14.880 breastfeeding women. First choice is to avoid 00:57:14.880 --> 00:57:18.940 the sun, but you would then, if you want to be 00:57:18.940 --> 00:57:20.539 out in the sun, you're just going to be wise 00:57:20.539 --> 00:57:22.599 with discussing with your healthcare provider, 00:57:22.760 --> 00:57:24.880 sunscreen choices that you feel like would be 00:57:24.880 --> 00:57:28.739 safe for you. And probably the best options are 00:57:28.739 --> 00:57:30.960 you're going to be your zinc oxide and your titanium 00:57:30.960 --> 00:57:33.619 dioxide, because they have been considered safe. 00:57:33.659 --> 00:57:35.559 They have been classified as safe and effective. 00:57:36.079 --> 00:57:39.139 Yeah. It's really interesting in Europe. It's 00:57:39.139 --> 00:57:42.340 actually. they, they, it's quite the, I wouldn't 00:57:42.340 --> 00:57:44.820 say the opposite, but they, they have a lot more, 00:57:44.840 --> 00:57:50.619 um, organic or chemical, um, um, additives in 00:57:50.619 --> 00:57:52.780 sunscreen that they've actually approved to be 00:57:52.780 --> 00:57:55.159 used over in Europe. But for some reason it hasn't 00:57:55.159 --> 00:57:57.099 caught on in the States and I don't know why. 00:57:57.420 --> 00:57:59.659 Uh, but it just seems like, yeah, the zinc oxide 00:57:59.659 --> 00:58:02.000 and titanium oxide, uh, were the ones that have 00:58:02.000 --> 00:58:04.300 been approved by the FDA. And I think there's 00:58:04.300 --> 00:58:06.280 being a little more cautious, uh, with the other 00:58:06.280 --> 00:58:08.360 ones just to make sure because cancer, unfortunately 00:58:08.360 --> 00:58:10.909 is a very, It's a long -term disease, so you 00:58:10.909 --> 00:58:13.449 have to monitor a population for a really long 00:58:13.449 --> 00:58:17.050 time to get really conclusive evidence. The first 00:58:17.050 --> 00:58:19.949 amount of evidence that we got for smoking causing 00:58:19.949 --> 00:58:23.929 cancer, I think, was in the 50s. I think it was 00:58:23.929 --> 00:58:27.469 this study that was done, and it was just done 00:58:27.469 --> 00:58:29.650 over an incredibly long period of time. Even 00:58:29.650 --> 00:58:33.889 tracking traumatic brain injury with football 00:58:33.889 --> 00:58:36.980 players took a really long time because... It 00:58:36.980 --> 00:58:38.719 didn't pop up immediately. It happened later 00:58:38.719 --> 00:58:41.039 in life. Huntington's disease is the same way 00:58:41.039 --> 00:58:42.679 if you want to look that up. It's one of those 00:58:42.679 --> 00:58:45.599 genetic diseases that doesn't happen to usually 00:58:45.599 --> 00:58:51.239 women until their 40s or 50s. So sometimes it 00:58:51.239 --> 00:58:53.719 seems really cut and dry like, oh, it should 00:58:53.719 --> 00:58:56.400 give you cancer or not. It's like, well, there 00:58:56.400 --> 00:58:59.880 are so many factors that go into somebody's life. 00:59:00.559 --> 00:59:03.320 that it's hard to isolate variables and you can't 00:59:03.320 --> 00:59:04.719 do experiments and be like, well, we're just 00:59:04.719 --> 00:59:06.800 going to stick you in a tanning bed for six months 00:59:06.800 --> 00:59:08.460 and see what happens. That would be very cruel. 00:59:09.460 --> 00:59:12.179 I wanted to bring up, because I know some people 00:59:12.179 --> 00:59:15.760 are just a little more skeptical of anything 00:59:15.760 --> 00:59:19.139 pharmaceutical and they don't want to use it 00:59:19.139 --> 00:59:21.300 because they prefer the natural way. Well, didn't 00:59:21.300 --> 00:59:25.559 we evolve to be in the sun? Why are we using 00:59:25.559 --> 00:59:27.199 these things to protect us against ourselves? 00:59:27.420 --> 00:59:29.119 And maybe it's actually causing more harm than 00:59:29.119 --> 00:59:34.829 good. And there's this great epidemiological 00:59:34.829 --> 00:59:37.469 study that was done with this natural population 00:59:37.469 --> 00:59:39.750 because you're looking at people. You want to 00:59:39.750 --> 00:59:42.349 look at two populations that are similar but 00:59:42.349 --> 00:59:44.550 have different behaviors so you can isolate variables. 00:59:45.250 --> 00:59:48.869 And if you don't think that the sun has any role 00:59:48.869 --> 00:59:52.030 to play in sunburn or cancer or aging or whatever, 00:59:52.309 --> 00:59:54.150 we have to look at people who primarily spend 00:59:54.150 --> 00:59:56.449 their time indoors and primarily spend their 00:59:56.449 --> 01:00:00.230 time outdoors. You look at construction workers, 01:00:00.409 --> 01:00:03.429 people who work in fields, etc. And you look 01:00:03.429 --> 01:00:05.769 at compared to people who work mainly indoors, 01:00:05.869 --> 01:00:07.769 people who work in mines, people work inside 01:00:07.769 --> 01:00:11.750 in offices, etc. And you can compare. First of 01:00:11.750 --> 01:00:16.010 all, you can randomize it so that you put enough 01:00:16.010 --> 01:00:18.590 people so that most of the variables are constant, 01:00:18.690 --> 01:00:21.150 like things like age and gender and race, etc. 01:00:21.650 --> 01:00:23.809 So that none of those things are going to be 01:00:23.809 --> 01:00:26.570 controlled. And then if you look at the variable, 01:00:26.809 --> 01:00:30.139 the independent variable. is a dependent variable. 01:00:31.860 --> 01:00:36.159 Yeah, it's the dependent variable, which is going 01:00:36.159 --> 01:00:40.780 to be sun exposure. The risk of skin cancer is 01:00:40.780 --> 01:00:44.320 just so much greater than in the group where 01:00:44.320 --> 01:00:47.179 they don't get exposed to the sun, which indicates 01:00:47.179 --> 01:00:50.039 that the sun really does play a role. And then 01:00:50.039 --> 01:00:52.139 you have to ask yourself, okay, How am I going 01:00:52.139 --> 01:00:53.920 to protect myself? And I think that should be 01:00:53.920 --> 01:00:55.960 your choice. Like you can use sunscreen or not. 01:00:56.059 --> 01:00:57.900 We don't care. We're just giving you information. 01:00:58.539 --> 01:01:01.079 But just be aware that, yes, it would be really 01:01:01.079 --> 01:01:04.539 nice if we had natural mechanisms against the 01:01:04.539 --> 01:01:07.579 sun. And I think sometimes you can do that by 01:01:07.579 --> 01:01:11.500 avoiding the sun or potentially wearing clothing 01:01:11.500 --> 01:01:15.440 if you consider that natural. But just know that 01:01:15.440 --> 01:01:18.039 if you don't wear sunscreen, that you are just 01:01:18.039 --> 01:01:21.719 going to be increasing your risk. of some of 01:01:21.719 --> 01:01:24.199 these maladies. But at the same time, if you 01:01:24.199 --> 01:01:29.000 use sunscreen, especially ones that could be 01:01:29.000 --> 01:01:31.440 deleterious to your health, like stuff that hasn't 01:01:31.440 --> 01:01:34.349 been approved by the FDA or... Um, even stuff 01:01:34.349 --> 01:01:36.809 that might have the nanoparticles or, um, there 01:01:36.809 --> 01:01:39.030 were actually even a couple of sunscreens that 01:01:39.030 --> 01:01:41.130 were found to be toxic and they're not included 01:01:41.130 --> 01:01:43.610 in sunscreens anymore. So that, you know, that 01:01:43.610 --> 01:01:46.389 definitely did happen. Exactly. So it's, it's 01:01:46.389 --> 01:01:49.349 really, it's, it's not a, you don't have to be 01:01:49.349 --> 01:01:51.710 on team sunscreen or team non sunscreen. There 01:01:51.710 --> 01:01:54.710 is there, there is a sunscreen out there that 01:01:54.710 --> 01:01:57.269 will probably work for you if you want to use 01:01:57.269 --> 01:02:00.070 it. And if you don't want to use it, that's fine. 01:02:00.570 --> 01:02:02.690 But remember that, you know, there's no such 01:02:02.690 --> 01:02:04.590 thing as a free lunch. And it would be really 01:02:04.590 --> 01:02:07.969 nice if nature was good to us. But sometimes 01:02:07.969 --> 01:02:11.840 she's just going to. Well, that's kind of a segue 01:02:11.840 --> 01:02:14.400 into let's talk about a little bit about what's 01:02:14.400 --> 01:02:18.159 misunderstood about sunscreens, okay? Some sunscreen 01:02:18.159 --> 01:02:21.340 myths. The first one is that sunscreen alone 01:02:21.340 --> 01:02:24.860 is enough to prevent skin cancer. And that's 01:02:24.860 --> 01:02:27.820 false because like Josh said earlier, no sunscreen 01:02:27.820 --> 01:02:31.179 blocks 100 % of ultraviolet light. And there's 01:02:31.179 --> 01:02:34.280 also other risk factors for skin cancer in addition 01:02:34.280 --> 01:02:36.980 to UV exposure like he also alluded to. You could 01:02:36.980 --> 01:02:39.280 be immunosuppressed or you have a family. history 01:02:39.280 --> 01:02:42.300 of skin cancer, or you're genetically predisposed. 01:02:42.460 --> 01:02:47.900 So the second myth is I have dark skin, so I 01:02:47.900 --> 01:02:52.059 don't need sunscreen. And that is not true. Although 01:02:52.059 --> 01:02:57.500 increased melanin, pardon me, although increased 01:02:57.500 --> 01:03:01.840 melanin does provides some protection against 01:03:01.840 --> 01:03:05.840 UV radiation. Studies have found that UV radiation 01:03:05.840 --> 01:03:09.699 does still induce damage to the skin in all skin 01:03:09.699 --> 01:03:11.579 colors. It doesn't matter what skin color you 01:03:11.579 --> 01:03:14.619 have. So no skin color or skin type is completely 01:03:14.619 --> 01:03:18.679 ultraviolet resistant. Yeah, and I would have 01:03:18.679 --> 01:03:20.519 to look at the data on this, but I'll bet you 01:03:20.519 --> 01:03:23.320 that the incident rate of melanoma or carcinoma 01:03:23.320 --> 01:03:25.780 is lower in people with darker skins, but it 01:03:25.780 --> 01:03:28.110 doesn't mean that you... You don't have the chance. 01:03:28.150 --> 01:03:30.070 It might just lower your risk of getting it, 01:03:30.090 --> 01:03:31.789 but you still have a risk of getting it if you 01:03:31.789 --> 01:03:35.809 don't apply sunscreen. Third myth, a baseline 01:03:35.809 --> 01:03:39.090 tan is protective against skin cancer. And that 01:03:39.090 --> 01:03:41.710 is absolutely not true. And again, remember we 01:03:41.710 --> 01:03:43.989 talked about avoid tanning booth devices because 01:03:43.989 --> 01:03:46.050 they're more dangerous than regular sunlight. 01:03:46.650 --> 01:03:49.510 They emit UV radiation at higher levels than 01:03:49.510 --> 01:03:55.219 what's found outside. And they emit more UVA 01:03:55.219 --> 01:03:59.260 light than UVB light. Remember, UVA light promotes 01:03:59.260 --> 01:04:03.000 tanning and premature aging, and UVB promotes 01:04:03.000 --> 01:04:06.780 sunburn. But both can cause damage to the skin 01:04:06.780 --> 01:04:10.420 and cause an increased risk for skin cancer. 01:04:10.719 --> 01:04:16.019 Interestingly, a tanning salon is similar to 01:04:16.019 --> 01:04:20.079 applying SPF 3 or 4. So again, it's only maybe 01:04:20.079 --> 01:04:21.699 going to prevent sunburn, but it's definitely 01:04:21.699 --> 01:04:24.659 not going to protect you against skin cancer 01:04:24.659 --> 01:04:27.300 or premature aging. Gotcha. That's really interesting. 01:04:27.960 --> 01:04:31.340 Okay. We talked about this too. Sunscreen prevents 01:04:31.340 --> 01:04:36.400 my daily vitamin D need. And so while 90 % of 01:04:36.400 --> 01:04:39.559 your vitamin D production is due to UV radiation 01:04:39.559 --> 01:04:44.360 exposure. Studies are really contradictory on 01:04:44.360 --> 01:04:47.280 looking at whether or not there's really an adverse 01:04:47.280 --> 01:04:51.079 effect on vitamin D by putting on sunscreen. 01:04:51.800 --> 01:04:55.360 Some of them said yes, some of them said no. 01:04:55.539 --> 01:04:57.980 So we don't have really a definitive answer to 01:04:57.980 --> 01:05:00.780 that yet. And like we mentioned earlier, there 01:05:00.780 --> 01:05:03.960 are so many other vitamin D sources in our food 01:05:03.960 --> 01:05:07.159 now, as well as taking just vitamin D supplements 01:05:07.159 --> 01:05:11.420 in general, that probably most of us won't become. 01:05:11.500 --> 01:05:14.300 vitamin D deficient. Yeah. And there's actually, 01:05:14.360 --> 01:05:17.659 you can go on Amazon and actually get a vitamin 01:05:17.659 --> 01:05:21.059 D test kit. Like you can test how much vitamin 01:05:21.059 --> 01:05:24.719 D is in your body and there are recommended levels 01:05:24.719 --> 01:05:27.800 that you should have in your body. And if you 01:05:27.800 --> 01:05:30.760 are below that, you should either A, be getting 01:05:30.760 --> 01:05:33.760 more sun, you know, especially early in the day, 01:05:33.780 --> 01:05:37.340 or B, you should be supplementing with vitamin 01:05:37.340 --> 01:05:40.409 D and, you know, you can get, you know. between 01:05:40.409 --> 01:05:44.530 3 ,000 to 6 ,000 international units pretty regularly. 01:05:45.090 --> 01:05:49.349 And we might do that in a future episode of the 01:05:49.349 --> 01:05:53.289 difference between basically the vitamins. Does 01:05:53.289 --> 01:05:58.429 dietary vitamin D, does that get to the places 01:05:58.429 --> 01:06:01.429 that it needs to go just as effectively as making 01:06:01.429 --> 01:06:03.909 it from the sun? Because it has to go through 01:06:03.909 --> 01:06:05.909 the mouth and it has to get metabolized, go to 01:06:05.909 --> 01:06:08.750 the bloodstream, blah, blah, blah. Um, so is 01:06:08.750 --> 01:06:11.869 it as effective of getting in and, um, but that's 01:06:11.869 --> 01:06:13.789 going to depend on the individual, which is why 01:06:13.789 --> 01:06:15.630 you should probably get some blood work done 01:06:15.630 --> 01:06:19.030 and know how much is in your body. Um, you can 01:06:19.030 --> 01:06:20.769 have a fun little test you can do before and 01:06:20.769 --> 01:06:22.949 after you'd like, you know, do it early in the 01:06:22.949 --> 01:06:25.030 morning, see what's going on, go out for the 01:06:25.030 --> 01:06:28.190 day and then test it again and then see how much 01:06:28.190 --> 01:06:30.769 vitamin D you've got. Um, and, and you can, you 01:06:30.769 --> 01:06:34.340 can understand, um, yeah, that. But to mom's 01:06:34.340 --> 01:06:36.340 point, yeah, you will lose some of that ability 01:06:36.340 --> 01:06:40.039 to make vitamin D with UVB light. But also due 01:06:40.039 --> 01:06:42.340 to sunscreen application, most people don't apply 01:06:42.340 --> 01:06:44.599 as much as they should just because it doesn't 01:06:44.599 --> 01:06:47.420 feel very good. And so you'll still make some 01:06:47.420 --> 01:06:49.480 throughout your body because most people don't 01:06:49.480 --> 01:06:52.320 cover their whole body with sunscreen. So remember, 01:06:52.460 --> 01:06:55.539 your whole body, whatever part of your skin is 01:06:55.539 --> 01:06:57.360 exposed to the sun, it's going to make vitamin 01:06:57.360 --> 01:07:00.329 D. So if you only got your face. and you didn't 01:07:00.329 --> 01:07:02.210 get the back of your hands, then that's still 01:07:02.210 --> 01:07:04.510 going to make the vitamin D. So it just depends 01:07:04.510 --> 01:07:08.829 on what you cover. Right. I liked this next one. 01:07:08.889 --> 01:07:12.070 There is sunscreen in my makeup, so I don't need 01:07:12.070 --> 01:07:16.389 to apply sunscreen. And usually makeup only has 01:07:16.389 --> 01:07:20.809 a sun protection factor of 15 in it. But as Josh 01:07:20.809 --> 01:07:22.510 has been alluding to, we usually don't put... 01:07:22.880 --> 01:07:25.699 enough makeup on to have enough sunscreen sun 01:07:25.699 --> 01:07:28.179 protection factor in it to protect us against 01:07:28.179 --> 01:07:30.619 sunburn so we should use sunscreen in addition 01:07:30.619 --> 01:07:32.639 to our makeup unless you're in a beauty pageant 01:07:32.639 --> 01:07:36.739 and then yeah then it's caked on um sitting under 01:07:36.739 --> 01:07:39.239 it i liked this one sitting under an umbrella 01:07:39.239 --> 01:07:42.840 is better than applying sunscreen well an umbrella 01:07:42.840 --> 01:07:47.179 can block the direct uv uv rays but guess what 01:07:47.500 --> 01:07:50.619 It doesn't block the rays that reflect off the 01:07:50.619 --> 01:07:52.179 ground. Think about when you're at the beach 01:07:52.179 --> 01:07:55.639 in the sand or water and stuff. So having the 01:07:55.639 --> 01:07:59.000 shade with the umbrella plus some sunscreen is 01:07:59.000 --> 01:08:03.559 going to be your best bet. And then all sunscreens 01:08:03.559 --> 01:08:06.940 work similarly, so it does not matter which one 01:08:06.940 --> 01:08:11.199 I use. This is not really the case. So like we 01:08:11.199 --> 01:08:13.769 talked about, you've got... physical versus chemical 01:08:13.769 --> 01:08:16.430 sunscreens. And then you've also got people with 01:08:16.430 --> 01:08:19.149 sensitive skin. So you need to look at the ingredients 01:08:19.149 --> 01:08:21.109 if you've got sensitive skin to make sure that 01:08:21.109 --> 01:08:23.850 you don't apply something that could be bothersome. 01:08:23.890 --> 01:08:27.329 It is recommended that the sunscreens with zinc 01:08:27.329 --> 01:08:30.949 or titanium in them are better for people with 01:08:30.949 --> 01:08:34.010 sensitive skin. Yeah. And one of the, the, the 01:08:34.010 --> 01:08:37.529 world experts based out of Newcastle for sunscreen 01:08:37.529 --> 01:08:40.329 and just, you know, photo aging recommends a 01:08:40.329 --> 01:08:43.569 broad spectrum sunscreen. Cause remember most 01:08:43.569 --> 01:08:46.069 sunscreens are just there to prevent you from 01:08:46.069 --> 01:08:48.909 getting sunburned, but with a broad spectrum 01:08:48.909 --> 01:08:51.670 sunscreen, and I would recommend also ones that 01:08:51.670 --> 01:08:54.770 are free of oxybenzone because that has been 01:08:54.770 --> 01:08:58.430 had small links. to leaking into the ocean and 01:08:58.430 --> 01:09:00.909 causing some coral reef destruction that will 01:09:00.909 --> 01:09:03.229 only applies if you live next to a coral reef. 01:09:03.369 --> 01:09:05.270 So if you live in Florida, if you live in Australia, 01:09:05.590 --> 01:09:13.529 but yeah, broad base protection. And he recommended 01:09:13.529 --> 01:09:17.909 that you should have a mixture of chemical versus 01:09:17.909 --> 01:09:20.229 physical. So you should have a bit of zinc oxide 01:09:20.229 --> 01:09:23.229 or titanium oxide with some of these other safe 01:09:23.229 --> 01:09:28.020 organic. molecules inside. By organic, I don't 01:09:28.020 --> 01:09:30.159 mean organic at the grocery store. Organic is 01:09:30.159 --> 01:09:32.939 a chemical term, meaning it has a carbon -based 01:09:32.939 --> 01:09:38.800 structure to it. Some of those chemicals can 01:09:38.800 --> 01:09:41.939 be found to be safe and effective on certain 01:09:41.939 --> 01:09:44.840 websites. You can look at some of the sunscreens 01:09:44.840 --> 01:09:48.699 in Europe that are sold either by L 'Oreal in 01:09:48.699 --> 01:09:51.779 France or by Boots in the UK, and they list their 01:09:51.779 --> 01:09:54.390 ingredients there. Um, and they haven't been 01:09:54.390 --> 01:09:56.470 formally approved by the FDA, but you can still 01:09:56.470 --> 01:09:59.649 get them in the U S um, and you can just compare 01:09:59.649 --> 01:10:01.130 the ingredients cause they've been, if you're 01:10:01.130 --> 01:10:03.369 fine with what's been approved in France and 01:10:03.369 --> 01:10:06.430 UK, then you can still get those things here. 01:10:06.550 --> 01:10:08.130 You know, they just, you know, they just haven't 01:10:08.130 --> 01:10:10.569 gotten the stamp of approval, um, by the food 01:10:10.569 --> 01:10:13.609 and drug administration. Um, and broad spectrum 01:10:13.609 --> 01:10:17.430 when Joshua talks about broad spectrum sunscreen, 01:10:17.689 --> 01:10:20.529 it means that it covers. It protects against 01:10:20.529 --> 01:10:25.270 both UVA and UVB light. Correct. The last little 01:10:25.270 --> 01:10:28.390 myth that I came across was that I do not need 01:10:28.390 --> 01:10:31.409 sunscreen on a cloudy day. That is an absolute 01:10:31.409 --> 01:10:36.590 no, because up to 80 % of UV rays can pass through 01:10:36.590 --> 01:10:39.710 clouds. So know that that's not a protective 01:10:39.710 --> 01:10:44.520 thing. So here are some takeaways for our discussion 01:10:44.520 --> 01:10:48.319 today about sunscreen. We want to avoid exposure 01:10:48.319 --> 01:10:52.699 to the sun and other sources of ultraviolet radiation, 01:10:52.800 --> 01:10:55.479 such as tanning beds and booths and sun lamps. 01:10:55.680 --> 01:10:58.920 So that, again, minimizing our exposure to the 01:10:58.920 --> 01:11:02.460 sun is going to give us better skin when we turn 01:11:02.460 --> 01:11:06.600 65, and also less chances for getting skin cancer. 01:11:07.529 --> 01:11:10.649 The sun's rays are the most direct and damaging 01:11:10.649 --> 01:11:14.470 between 10 a .m. and 4 p .m., so try to avoid 01:11:14.470 --> 01:11:16.810 getting exposed to the sun during those time 01:11:16.810 --> 01:11:19.010 periods as much as possible, or if that's not 01:11:19.010 --> 01:11:20.909 possible, at least use some of the protection 01:11:20.909 --> 01:11:24.149 factors that we've talked about. Sunburn can 01:11:24.149 --> 01:11:26.970 occur on a cloudy or an overcast day, as we've 01:11:26.970 --> 01:11:30.149 mentioned, so you want to be aware of that. And 01:11:30.149 --> 01:11:34.200 wearing protective clothing is a good idea. like 01:11:34.200 --> 01:11:36.640 tightly woven fabrics that won't allow the sun 01:11:36.640 --> 01:11:38.640 is going to be good. Now, like Josh says, I mean, 01:11:38.680 --> 01:11:41.000 it has been a hundred plus degrees in Texas all 01:11:41.000 --> 01:11:43.020 summer long. Finally, we're getting a little 01:11:43.020 --> 01:11:45.659 bit of a break from that. So, but I have still 01:11:45.659 --> 01:11:47.760 seen the construction workers in Texas wearing 01:11:47.760 --> 01:11:50.579 long sleeves because it's, you know, it's just 01:11:50.579 --> 01:11:53.279 protecting them from being getting sunburned 01:11:53.279 --> 01:11:57.300 and skin cancer. Absolutely. When you go to the 01:11:57.300 --> 01:11:59.840 beach or if you're at the pool, try to use a 01:11:59.840 --> 01:12:02.960 beach umbrella whenever possible as one of those 01:12:02.960 --> 01:12:06.039 mechanisms to reduce your exposure to ultraviolet 01:12:06.039 --> 01:12:09.979 radiation. Remember that water and wet clothing 01:12:09.979 --> 01:12:13.420 will allow transmission of ultraviolet radiation 01:12:13.420 --> 01:12:17.060 to your skin. So even if your skin is completely 01:12:17.060 --> 01:12:20.319 submerged in the water, you still need to count 01:12:20.319 --> 01:12:23.159 that time as part of your sun exposure time because 01:12:23.159 --> 01:12:26.260 the water does not protect you, you know, but 01:12:26.260 --> 01:12:30.729 only 5 % against ultraviolet radiation. Try to 01:12:30.729 --> 01:12:34.350 look for a sun protection factor product of 15 01:12:34.350 --> 01:12:37.130 or greater to give you greater protection against 01:12:37.130 --> 01:12:41.789 long -term effects of skin cancer and premature 01:12:41.789 --> 01:12:45.949 aging, but also sunburn as well. And I would 01:12:45.949 --> 01:12:48.810 say on that, the lighter your skin tone, I would 01:12:48.810 --> 01:12:51.989 say get a higher SPF. Because remember, SPF is 01:12:51.989 --> 01:12:55.970 calculated by the amount of time that it took 01:12:55.970 --> 01:12:59.390 for your skin to burn with or without. a sunscreen 01:12:59.390 --> 01:13:02.329 and if you're a darker skin person it's going 01:13:02.329 --> 01:13:04.109 to take a lot longer so you might be able to 01:13:04.109 --> 01:13:07.010 get away with an spf of 15 to 30 whereas someone 01:13:07.010 --> 01:13:09.630 who's a little more paler might need a 50 to 01:13:09.630 --> 01:13:12.569 a 75 and then also remember your application 01:13:12.569 --> 01:13:14.909 method and that it might not be as thorough as 01:13:14.909 --> 01:13:16.710 the laboratory conditions so you might want to 01:13:16.710 --> 01:13:19.270 you know get something a little bit higher to 01:13:19.270 --> 01:13:21.630 increase the concentration of that inside of 01:13:21.630 --> 01:13:24.319 it Just a reminder, as Joshua just mentioned 01:13:24.319 --> 01:13:27.159 a few minutes ago, that broad spectrum sunscreen 01:13:27.159 --> 01:13:30.319 product. So if you can find one that has both 01:13:30.319 --> 01:13:33.760 the chemical as well as the physical sunscreen 01:13:33.760 --> 01:13:35.880 components, that's going to be your best bet, 01:13:36.020 --> 01:13:39.720 especially in people who have a sun induced disorder. 01:13:40.159 --> 01:13:45.659 So like maybe you are. I'm sorry, I'm not even 01:13:45.659 --> 01:13:47.460 thinking of what a sun induced disorder would 01:13:47.460 --> 01:13:51.939 be right now. I apologize. photo toxicity or 01:13:51.939 --> 01:13:55.000 photo allergy? Well, yeah, but it's not taking 01:13:55.000 --> 01:13:56.960 photosynthesizing drugs because that's a different 01:13:56.960 --> 01:13:58.859 thing. But yeah, you could have a photo allergy. 01:13:58.880 --> 01:14:00.220 I guess if you're in the sun, you can definitely 01:14:00.220 --> 01:14:03.060 have issues associated with that. And then if 01:14:03.060 --> 01:14:05.000 you want to just reduce your sun exposure as 01:14:05.000 --> 01:14:07.699 most as possible. So that broad spectrum product 01:14:07.699 --> 01:14:11.640 would be the best for that. Make sure you apply 01:14:11.640 --> 01:14:14.140 it at least 15 minutes before your sun exposure. 01:14:14.989 --> 01:14:17.329 And then that whole thing about the one ounce 01:14:17.329 --> 01:14:20.109 of sunscreen over your body, don't put it in 01:14:20.109 --> 01:14:23.609 your eyes, but you want to put it over your face, 01:14:23.649 --> 01:14:27.050 neck, arms, shoulders, the front and back torso, 01:14:27.090 --> 01:14:29.569 and each leg and the top of your, don't forget 01:14:29.569 --> 01:14:33.109 the tops of your feet. And men, especially, or 01:14:33.109 --> 01:14:35.289 gals with short hair, don't forget your ears 01:14:35.289 --> 01:14:37.170 and the back of your neck. Yeah, the back of 01:14:37.170 --> 01:14:38.810 the neck is the one that always gets me. Yes. 01:14:39.659 --> 01:14:42.260 And remember, we want to use a sunscreen that's 01:14:42.260 --> 01:14:45.840 the most substantive or is the most water resistant 01:14:45.840 --> 01:14:48.060 so that it will stay on your skin for as long 01:14:48.060 --> 01:14:51.880 as possible. And reapply it according to the 01:14:51.880 --> 01:14:55.039 label instructions, 40 or 80 minutes with the 01:14:55.039 --> 01:14:57.600 water resistant products. And then at least every 01:14:57.600 --> 01:15:02.960 two hours, if you're not being exposed to water, 01:15:03.039 --> 01:15:04.899 but you're just sweating or just outside just 01:15:04.899 --> 01:15:10.140 for that maximum effect. Remember that you check 01:15:10.140 --> 01:15:12.960 the expiration date for a sunscreen product because 01:15:12.960 --> 01:15:15.899 they can expire. Personal experience with my 01:15:15.899 --> 01:15:18.520 younger son, had it used, gave him sunscreen 01:15:18.520 --> 01:15:21.340 all over his back, went to South Padre, poor 01:15:21.340 --> 01:15:24.560 child got extremely sunburned. Check the expiration 01:15:24.560 --> 01:15:28.909 date. Um, snow and sand reflect ultraviolet radiation. 01:15:29.289 --> 01:15:32.170 So you want to take proper precautions if you're 01:15:32.170 --> 01:15:34.850 skiing or at the, at the beach, you want to make 01:15:34.850 --> 01:15:36.510 sure. Yeah. I have a funny story about that. 01:15:36.550 --> 01:15:39.189 My, uh, my college roommates, we went on a trip 01:15:39.189 --> 01:15:41.590 right after we all graduated and we went to, 01:15:41.590 --> 01:15:44.649 um, we went to Mount Rainier in Washington in 01:15:44.649 --> 01:15:47.529 May and it was, it was literally covered in snow. 01:15:47.770 --> 01:15:49.970 Uh, and we did this hike that was just covered 01:15:49.970 --> 01:15:54.210 in snow. And when we got back to our place, I 01:15:54.210 --> 01:15:57.409 looked at my friend. And the bottom of his eyebrows 01:15:57.409 --> 01:16:00.430 were completely burned is because the sun was 01:16:00.430 --> 01:16:02.310 shining really bright that day and reflecting 01:16:02.310 --> 01:16:05.510 off of the snow. And so literally his eyelids 01:16:05.510 --> 01:16:08.590 and eyebrows were just completely charred. And 01:16:08.590 --> 01:16:12.189 it was, oh my gosh. So this really is a, if you 01:16:12.189 --> 01:16:14.170 are in a place with really reflective things 01:16:14.170 --> 01:16:16.449 like sand or snow, yeah, it really can happen. 01:16:16.630 --> 01:16:18.829 I've seen that happen to my friend and we've 01:16:18.829 --> 01:16:22.670 talked about it to this day. Make sure that you 01:16:22.670 --> 01:16:24.729 keep your sunscreen out of direct sunlight when 01:16:24.729 --> 01:16:27.569 you store it because that can reduce its potency. 01:16:27.850 --> 01:16:31.949 That's how it works. Yes. And continue to use 01:16:31.949 --> 01:16:34.189 sunscreen if you're taking a photosensitizing 01:16:34.189 --> 01:16:36.289 drug, if you're taking a drug that makes you 01:16:36.289 --> 01:16:40.109 more sensitive to the sun, or if you've got any 01:16:40.109 --> 01:16:45.270 other types of skin -associated sun disorders, 01:16:45.550 --> 01:16:53.109 just make sure you use a sunscreen. And if you 01:16:53.109 --> 01:16:55.869 develop any type of an allergic reaction to a 01:16:55.869 --> 01:16:57.670 sunscreen, it kind of goes without saying, stop 01:16:57.670 --> 01:16:59.930 using it, you know, and then you might need to 01:16:59.930 --> 01:17:01.789 contact your physician to figure out what's going 01:17:01.789 --> 01:17:04.350 to work best for you. And that's about it. That's 01:17:04.350 --> 01:17:06.789 all I got today about sunscreens. Man, I feel 01:17:06.789 --> 01:17:09.369 like this is such a technical topic for something 01:17:09.369 --> 01:17:12.069 that I thought was so simple. Me too. I learned 01:17:12.069 --> 01:17:15.029 so much from this. And for all of our listeners, 01:17:15.229 --> 01:17:17.090 I really hope that you did too. I know there's 01:17:17.090 --> 01:17:20.720 a lot of information in this episode. And we 01:17:20.720 --> 01:17:22.739 really hope that you learn something and pick 01:17:22.739 --> 01:17:25.180 a sunscreen that's safe for you and your family. 01:17:26.060 --> 01:17:28.960 And we hope that you have fun in the sun. I mean, 01:17:28.979 --> 01:17:31.180 nothing is better than just going outside on 01:17:31.180 --> 01:17:33.500 a nice, wonderful day and enjoying yourself. 01:17:34.079 --> 01:17:37.880 And your future self will thank you for doing 01:17:37.880 --> 01:17:40.680 the right thing now. As my mom's looking at me 01:17:40.680 --> 01:17:42.100 like, yeah, you better put on some sunscreen 01:17:42.100 --> 01:17:45.210 because you're going to be my age one day. That's 01:17:45.210 --> 01:17:46.609 right. And I'll tell you right now. You think 01:17:46.609 --> 01:17:48.949 you see wrinkles now. That's the thing about 01:17:48.949 --> 01:17:52.789 being a health communicator. You can often feel 01:17:52.789 --> 01:17:54.970 the weight of being a huge hypocrite because 01:17:54.970 --> 01:17:58.289 the amount of times that I put on sunscreen is 01:17:58.289 --> 01:18:00.909 so. He probably doesn't even own any. Yeah, I 01:18:00.909 --> 01:18:04.189 actually just bought some yesterday after doing 01:18:04.189 --> 01:18:06.210 research on this episode. I was like, I need 01:18:06.210 --> 01:18:10.750 to buy some good sunscreen. So I definitely am 01:18:10.750 --> 01:18:15.279 in y 'all's boat. where it's easy to talk about 01:18:15.279 --> 01:18:17.199 and learn, but then when you're doing it, you 01:18:17.199 --> 01:18:18.920 just want to go outside. You don't want to do 01:18:18.920 --> 01:18:21.500 any of the prep work. So making it a part of 01:18:21.500 --> 01:18:24.539 your routine will also be super helpful. But 01:18:24.539 --> 01:18:26.779 also forgive yourself for making mistakes. Even 01:18:26.779 --> 01:18:29.039 if you put it on one day a week, it's better 01:18:29.039 --> 01:18:33.600 than zero. So start small. And we really hope 01:18:33.600 --> 01:18:36.199 that you've enjoyed this episode and we hope 01:18:36.199 --> 01:18:38.039 to see you next time. So with that being said, 01:18:38.100 --> 01:18:41.399 my name is Josh Klaus. and i'm jennifer seltzer 01:18:41.399 --> 01:18:43.640 and this has been another episode of your mom 01:18:43.640 --> 01:18:46.960 on drugs see you soon see you later that was 01:18:46.960 --> 01:18:48.619 fun that was really fun
