Welcome to Stuff you Should Know from how 0:01:26.040 --> 0:01:35.720 Stuff Works dot com. Hey, welcome to the podcast. I'm 0:01:35.840 --> 0:01:40.880 Josh Clark, There's Charles W. Chuck Bright, there's Jerry's Stuff 0:01:40.880 --> 0:01:49.720 you Should Know. That summer sunburn and addition your tan, well, 0:01:49.760 --> 0:01:51.360 I did think it was kind of funny. I probably 0:01:51.360 --> 0:01:54.559 have more sun on my face than I've had in years. Yes, 0:01:55.480 --> 0:01:57.440 very easily, I would say, And I've been in the 0:01:57.480 --> 0:01:59.480 sun a lot more lately. But I have been applying 0:01:59.480 --> 0:02:04.760 sunscrew green. But as you will see very shortly, I 0:02:04.840 --> 0:02:07.160 haven't been the best at reapplying it. No, That's what 0:02:07.280 --> 0:02:09.880 I'm guilty of too, And so I end up getting 0:02:09.919 --> 0:02:12.600 a tan, and then, of course, like a dummy, I'm like, hey, 0:02:12.680 --> 0:02:16.480 tants look pretty good. I look fox people look good 0:02:16.480 --> 0:02:18.160 with a little bit of a tan, which is just 0:02:18.360 --> 0:02:21.040 how you fall into that trap of doing what's ultimately 0:02:21.160 --> 0:02:25.120 very bad for yourself. Next up, Ascot's going down the 0:02:25.120 --> 0:02:28.120 George Hamilton's route. But the rest of my body, well, 0:02:28.400 --> 0:02:31.280 my lower my lower arms are tan and my face 0:02:31.360 --> 0:02:34.119 is tan. Do you have like milk bottle calves? Tell 0:02:34.160 --> 0:02:38.320 me everything else is white? Take off your pants, they're 0:02:38.360 --> 0:02:45.480 already off. Okay, as always, your pants really are off? Um, Jerry, 0:02:45.480 --> 0:02:48.560 did you know Chuck's pants are off? She's known for 0:02:48.639 --> 0:02:52.960 nine years? Remember the the T shirt that listener made 0:02:52.960 --> 0:02:56.280 his pants off? Mike's on or Mike's on pants off. 0:02:56.280 --> 0:02:57.720 I can't remember the order that we do it. A 0:02:57.760 --> 0:03:01.320 wax on, wax off. I think, uh, this one's long 0:03:01.360 --> 0:03:05.240 overdo though, I think and pilot under our general public 0:03:05.280 --> 0:03:09.000 service casts. Yeah, there's a lot of info that's floating 0:03:09.040 --> 0:03:13.560 around that is wrong. Yeah, starting with the idea that 0:03:13.840 --> 0:03:18.520 tans are healthy or even protective. Yeah, Like, well, we'll 0:03:18.520 --> 0:03:21.120 go through all these and bust some myths, but handing 0:03:21.120 --> 0:03:24.720 bad company saying like oh you need that vitamin D yeah, 0:03:24.919 --> 0:03:28.200 or hey that based hand that will help you not burn. 0:03:29.000 --> 0:03:30.840 We'll go through all this we're going to but let's 0:03:30.840 --> 0:03:34.359 start Let's start where everything starts, Chuck, Let's start with 0:03:34.400 --> 0:03:38.600 the sun. Alright, Sorry, So the Sun is streaming down. 0:03:38.680 --> 0:03:42.480 You're familiar with the Sun. Our star, closest star, divides light, heat, 0:03:42.920 --> 0:03:46.240 that kind of stuff. It's also bearing down on us 0:03:46.800 --> 0:03:50.400 deadly radiation, trying to kill us all the time, right, 0:03:50.720 --> 0:03:54.760 And there's three types, Well, there's three kinds of um 0:03:55.000 --> 0:03:57.600 energy that the Sun shoots at us. There's infrared heat, 0:03:58.120 --> 0:04:02.720 there's visible light light, and then there's ultra violet light 0:04:03.120 --> 0:04:06.080 scar one ultra violet radiation, right, and then you can 0:04:06.120 --> 0:04:09.600 break down ultra violet radiation into three more components, u 0:04:09.640 --> 0:04:15.200 v A, UVB, and UVC. Actually, if we didn't have 0:04:15.200 --> 0:04:17.520 our atmosphere, we'd all be dead right now, just because 0:04:17.520 --> 0:04:22.240 the UVC. It's extremely deadly. But do right, if you're 0:04:22.240 --> 0:04:25.640 an astronaut, you gotta worry about UVC, But those of 0:04:25.720 --> 0:04:27.279 us here on Earth, we don't. We only have to 0:04:27.279 --> 0:04:31.440 worry about u v A and UVB. And for decades, 0:04:31.480 --> 0:04:34.600 ever since we started thinking about protecting ourselves from the sun, 0:04:34.880 --> 0:04:39.040 we've basically been focused on UVB. Yeah. UVB is what 0:04:39.080 --> 0:04:42.039 will sun burn you, right, which is why everybody wants 0:04:42.040 --> 0:04:44.600 to protect themselves from it. But it turns out, as 0:04:44.640 --> 0:04:48.320 we'll see, u v A is not it's even worse 0:04:48.360 --> 0:04:52.440 than UVB. No, it really isn't. But those are the 0:04:52.480 --> 0:04:56.080 three kinds. And when sunlight comes here on Earth, and 0:04:56.200 --> 0:04:58.960 even when it doesn't, if it's reflected on a cloudy 0:04:59.040 --> 0:05:01.640 day or through fog or something like that, don't be fooled, no, 0:05:01.920 --> 0:05:04.120 because U v A still getting through. And as you'll see, 0:05:04.160 --> 0:05:06.479 you need to protect yourself as a matter of fact, 0:05:06.640 --> 0:05:10.200 because we will see some people recommend that you use 0:05:10.480 --> 0:05:14.360 sunscreen every day, all over your body, every day, indoors 0:05:14.480 --> 0:05:17.760 and out. Well, if you do that, you will probably 0:05:17.800 --> 0:05:22.920 never get skin cancer, that's right, unless it's genetic. Yeah, 0:05:23.160 --> 0:05:26.640 but you're definitely helping yourself out right. Uh. So you're 0:05:26.680 --> 0:05:30.920 talking about that sunlight beaming down and fog and cloud 0:05:30.960 --> 0:05:33.720 cover and all that stuff. You probably, if you've ever 0:05:33.760 --> 0:05:37.440 been snow skiing, gotten sunburned because on a sunny day 0:05:37.480 --> 0:05:40.840 that snow will reflect about of UV light. Yeah, so 0:05:41.080 --> 0:05:43.440 you get the sun coming down on you and then 0:05:43.640 --> 0:05:45.920 you're also getting a second dose of it reflected from 0:05:45.920 --> 0:05:49.520 the snow at a rate. If you're at the beach 0:05:49.560 --> 0:05:51.240 and you wonder why you might burn a little more 0:05:51.240 --> 0:05:53.920 at the beach. It's because that sand does the same 0:05:53.960 --> 0:05:57.720 thing to a rate of about where you will not 0:05:58.400 --> 0:06:02.600 get sunburned, they say, is in a greenhouse. Yeah, did 0:06:02.640 --> 0:06:05.440 you know that. I didn't know that. You're you'll sweat 0:06:05.480 --> 0:06:08.400 to death, sure, and you can still get um tan, 0:06:08.600 --> 0:06:12.080 but you won't burn. Yeah. Apparently glass is a substance 0:06:12.240 --> 0:06:15.760 that absorbs UV radiation. This is a big thing that 0:06:15.839 --> 0:06:18.320 I realized chucking. I just kind of touched upon it 0:06:18.960 --> 0:06:22.680 for my entire life. I thought that sunburn was like 0:06:22.800 --> 0:06:27.520 a tan gone too far, or conversely, that you got 0:06:27.560 --> 0:06:30.239 sun burned and then you got tanned as a result 0:06:30.320 --> 0:06:32.880 of sun burn, and then you were fine. Oh yeah, 0:06:32.960 --> 0:06:35.680 like the people that are like, oh, always burn on 0:06:35.760 --> 0:06:38.160 day one and then it turns it turns into a tan, right, 0:06:38.160 --> 0:06:39.560 and then I keep that for the summer and I 0:06:39.560 --> 0:06:42.440 don't even need some block after that, right now, Actually, 0:06:42.480 --> 0:06:46.279 a sun tan and a sun burn are two different things, 0:06:46.680 --> 0:06:51.000 and then the result of two different types of UV radiation. Yeah, 0:06:51.000 --> 0:06:55.039 that people that say that stuff are completely talking out 0:06:55.120 --> 0:06:58.520 of their butts, right, Don't listen to them, listen to 0:06:58.640 --> 0:07:01.920 us instead. Yeah, because there's actual signs behind the UVB 0:07:02.120 --> 0:07:04.919 is what causes sun burns. UV A rays are different, 0:07:05.640 --> 0:07:09.000 and they they are what ultimately I think it's a 0:07:09.000 --> 0:07:14.800 deeper penetration. They will ultimately cause like wrinkly skin, right 0:07:15.080 --> 0:07:19.280 and like internal collagen damage and stuff like that. Right. 0:07:19.320 --> 0:07:24.600 So uv A for aging, UVB for burning, right, yes, 0:07:24.680 --> 0:07:27.200 and combines with both. You look like that lady, And 0:07:27.240 --> 0:07:31.360 there's something about Mary made out with the dog. So 0:07:32.000 --> 0:07:35.640 we are It's not like we're just complete, Um, we're 0:07:35.680 --> 0:07:37.800 just completely at the mercy of the sun. Right. We 0:07:37.880 --> 0:07:43.440 have a natural reactions to sunlight that are kind of 0:07:43.520 --> 0:07:47.640 protective measures, but really more than anything, we're finding nowadays 0:07:47.960 --> 0:07:50.840 that they're huge red flags that are meant to say, like, 0:07:51.240 --> 0:07:55.160 get out of the sun. You're being internally damaged on 0:07:55.240 --> 0:08:00.320 a molecular level right now, hence your sunburn. But it 0:08:00.360 --> 0:08:03.120 turns out the tan is the same thing. Basically, it's 0:08:03.160 --> 0:08:06.000 a it's a big red flag or a big brown 0:08:06.040 --> 0:08:12.360 flag that says, um, you're undergoing genetic damage currently. You 0:08:12.400 --> 0:08:14.880 may want to get out of the sun, not go 0:08:15.080 --> 0:08:16.880 laid by the pools some more. You got your tan, 0:08:17.000 --> 0:08:19.760 you're fine. Yeah, when you're getting that tan, what that 0:08:19.920 --> 0:08:24.120 is is a pigment called melanin, and it is produced 0:08:24.240 --> 0:08:29.120 in reaction to that. Uh, I guess you v B 0:08:29.840 --> 0:08:32.199 u v A u v A and not gonna get 0:08:32.240 --> 0:08:36.000 this v A ting right, should remember that? Yeah, but 0:08:36.000 --> 0:08:39.120 it's tough to it's tough to separate the burn from 0:08:39.120 --> 0:08:40.960 the tan and think that there are two different things. 0:08:41.040 --> 0:08:44.040 After thinking that they're you know, related to all your life, 0:08:44.080 --> 0:08:47.880 you know, well, it's It's why tanning beds use mainly 0:08:48.000 --> 0:08:50.679 u v A light because you don't want to. They 0:08:50.720 --> 0:08:52.920 don't want you to sunburn when you go to the 0:08:52.960 --> 0:08:55.160 tanning salon because then you'll be like, wait a minute, 0:08:55.200 --> 0:08:57.040 that's not how it's supposed to work. And you don't 0:08:57.080 --> 0:09:00.400 get tann from UVB, so why even included? And if 0:09:00.440 --> 0:09:02.600 you don't have to, well, yeah, and here's the deal, though, 0:09:02.640 --> 0:09:03.920 I guess I might as well go ahead and let 0:09:03.920 --> 0:09:07.360 the cat out of the bag with the tanning beds. Um. 0:09:07.440 --> 0:09:09.360 One of the things, one of the bogus things that 0:09:09.400 --> 0:09:11.520 they will tell you is like, no, that your body 0:09:11.559 --> 0:09:14.160 needs vitamin D and so go to the tanning bed 0:09:14.640 --> 0:09:19.680 because it's safer than being in the sun. One bs. Uh, 0:09:19.800 --> 0:09:23.920 you get vitamin D from UVB, not uv A, and 0:09:23.960 --> 0:09:27.079 tanning beds use uv A to get you tanned, so 0:09:27.120 --> 0:09:32.120 it's that's completely bogus to begin with. UM. One recent 0:09:32.280 --> 0:09:36.520 estimate UH suggested indoor channing caused about four hundred and 0:09:36.520 --> 0:09:40.440 twenty thousand cases of skins can't skin cancer United States 0:09:40.520 --> 0:09:43.959 every year. That's about double the number of lung cancer 0:09:44.160 --> 0:09:48.120 linked to smoking UH, and twelve states at this point 0:09:48.200 --> 0:09:51.840 of outlawed tanning beds for miners under eighteen years old. 0:09:52.120 --> 0:09:54.640 That seems smart. I got one more stat for you. 0:09:55.559 --> 0:09:57.920 People who used tanning beds for the first time before 0:09:57.920 --> 0:10:01.360 the age of thirty UH, presuming they will. You know, 0:10:01.400 --> 0:10:05.200 it's not a one off, have a seventy increased risk 0:10:05.240 --> 0:10:09.480 in developing melanoma. The other don't go to tanning beds people. No, 0:10:09.640 --> 0:10:11.920 that's a creat advice, Chuck Man. I mean, and a 0:10:11.960 --> 0:10:14.280 lot of people also think, like melanoma nothing, you just 0:10:14.320 --> 0:10:17.439 cut it out, it's fine. Actually, melanoma can spread, can 0:10:17.480 --> 0:10:22.360 metastasize really quickly, and it is a very dangerous form 0:10:22.400 --> 0:10:25.360 of cancer. So don't take that lightly at all. Plus, 0:10:25.400 --> 0:10:27.520 if you're going to a tanning bed, you're probably doing 0:10:27.559 --> 0:10:30.080 it for your looks. Have a little foresight because what 0:10:30.120 --> 0:10:34.080 you're doing is subjecting your body to advanced hyper aging. 0:10:34.360 --> 0:10:38.959 You're gonna age prematurely from and that whole like. You know, 0:10:39.200 --> 0:10:41.960 people will say, I don't care, I'm young. I want 0:10:41.960 --> 0:10:45.840 to look tann and look good. Um, that's why we 0:10:45.880 --> 0:10:48.520 have nanny states to choose for you, because you're too 0:10:48.520 --> 0:10:53.280 stupid to choose for yourself. Uh was that, judge, No, 0:10:53.880 --> 0:10:55.880 we're trying to help people. I mean, this is it's 0:10:55.880 --> 0:10:59.480 a danger. So the guy with a freshly tanned face, 0:11:00.280 --> 0:11:02.240 let's let's go back to the skin and what the 0:11:02.280 --> 0:11:04.480 skin is doing. Okay, all right, should we take a 0:11:04.520 --> 0:11:07.520 break first, a little worked up? We can. All right, 0:11:07.559 --> 0:11:31.560 let's take a little break, get into the skin. So chuck, 0:11:31.600 --> 0:11:34.640 we're we're back on the skin. You said that when 0:11:35.000 --> 0:11:40.240 u v A interacts with our skin, melana sites are 0:11:40.400 --> 0:11:44.199 stimulated to produce melanin. Correct. Yeah, totally bailed on that. 0:11:44.360 --> 0:11:47.600 And melanin is a pigment and one of the roles 0:11:47.640 --> 0:11:53.679 that it plays is to absorb but actually absorbs radiation 0:11:53.840 --> 0:11:58.760 u v A radiation and under normal circumstances, I think, um, 0:12:00.160 --> 0:12:04.400 literally nine times out of a thousand, it when it 0:12:04.440 --> 0:12:08.080 interacts with a photon of uv A radiation, it takes 0:12:08.160 --> 0:12:13.480 that photon and it basically absorbs it into its molecular 0:12:13.520 --> 0:12:18.840 structure and it spits it out as waste heat. So 0:12:18.920 --> 0:12:21.400 it takes the radiation and turns it into something that's 0:12:21.480 --> 0:12:24.920 just it's just heat. It's not deadly, it's not dangerous 0:12:24.960 --> 0:12:28.280 any longer. Yeah, and that this isn't something that happens overnight. 0:12:28.320 --> 0:12:30.720 It takes a little while to produce this melanin, which 0:12:30.760 --> 0:12:33.240 is why you don't go out and get tan in 0:12:33.280 --> 0:12:38.720 a day. Um. There's a longstanding myth that people who 0:12:38.800 --> 0:12:45.240 have melanin production constantly, people with darker skin tones, um, 0:12:45.320 --> 0:12:48.440 that they can't burn and that they can't get skin cancer. 0:12:48.480 --> 0:12:51.679 And that's wrong on both accounts. It is um more 0:12:51.760 --> 0:12:56.240 difficult for somebody with very dark skin tone to get 0:12:56.320 --> 0:13:00.880 some burned. But I was cancer right, Yeah, there's a 0:13:00.880 --> 0:13:03.720 lower prevalence. But I was reading, Um, I was reading 0:13:03.760 --> 0:13:07.640 up on it, and I saw some dermatologists said, if 0:13:07.679 --> 0:13:11.360 you have skin, you can get some burned. Just give 0:13:11.400 --> 0:13:13.760 it enough time, under the right conditions, you'll get some burned. 0:13:14.040 --> 0:13:17.040 And then yes, skin cancer is a thing as well. Um, 0:13:17.240 --> 0:13:21.640 people of Uh, the fairier complexion, the worst you're going 0:13:21.679 --> 0:13:26.360 to burn, and the um higher. Your incidence of getting 0:13:26.360 --> 0:13:29.120 skin cancer from being out in the sun is but 0:13:29.280 --> 0:13:32.320 it can happen. It's just a spectrum. But on on 0:13:32.480 --> 0:13:34.560 the other end of the darkest end of the spectrum. 0:13:34.880 --> 0:13:36.680 That doesn't mean it doesn't happen. It just means it 0:13:36.720 --> 0:13:39.480 happens last. So all of this applies to people of 0:13:39.520 --> 0:13:42.439 all different skin tones. Yeah, and like we said before, 0:13:42.559 --> 0:13:46.600 when it comes to uv A that's a deeper penetrating 0:13:47.480 --> 0:13:51.400 light into the skin, it's gonna destroy collagen. It's a 0:13:51.400 --> 0:13:54.640 structural protein and that collagen goes away, and that's when 0:13:54.679 --> 0:13:59.680 your skin becomes less elastic, less smooth, and that is 0:13:59.720 --> 0:14:02.360 what you think of when you think of wrinkles. Yeah, 0:14:02.400 --> 0:14:06.320 they found this University of Michigan study found that when 0:14:06.840 --> 0:14:11.960 the participants were exposed to uv A light, um something 0:14:12.040 --> 0:14:18.240 called matrix metallo proton as one was um produced, and 0:14:18.280 --> 0:14:22.280 that that goes and destroys collagen. It's like it's one 0:14:22.280 --> 0:14:25.600 of the body's natural processes breaking down these cell walls 0:14:25.640 --> 0:14:29.000 that gives skin structure, and that leads to wrinkles and 0:14:29.040 --> 0:14:32.960 saggy skin eventually. And they found that even when you 0:14:33.000 --> 0:14:38.640 started to tan the um, the MMP one production didn't 0:14:38.680 --> 0:14:41.600 decrease at all. It just kept going. So this idea 0:14:41.680 --> 0:14:43.720 that when you developed a tan when you're melon in 0:14:43.800 --> 0:14:48.280 production kicks in that um you're being protected, that's actually 0:14:48.320 --> 0:14:50.680 not the case at all. We're finding that it's actually 0:14:50.720 --> 0:14:54.240 just it's a it's a defense mechanism, but it's not 0:14:54.440 --> 0:14:59.000 a protective measure that keeps everything fine once your tans set. 0:15:00.240 --> 0:15:03.240 I looked up just a quadruple check about the base 0:15:03.320 --> 0:15:09.320 tan theory um and it's complete bs uh. They found 0:15:09.360 --> 0:15:12.520 that a base hand provides and we'll talk about SPF 0:15:13.080 --> 0:15:19.320 son uh protection factor. Right, you know why hesitant to less? 0:15:19.320 --> 0:15:23.640 Second there, a base hand provides an SPF of three 0:15:23.880 --> 0:15:28.560 or less, which means it buys you about ten extra 0:15:28.600 --> 0:15:33.640 minutes in the sun and so little that the chief 0:15:33.720 --> 0:15:39.360 of dermatologic surgery at Yale said it's essentially completely meaningless 0:15:39.400 --> 0:15:42.920 in terms of providing protection. So and they in fact, 0:15:43.000 --> 0:15:46.480 they say it can have the reverse effect because people 0:15:47.600 --> 0:15:50.520 are under this assumption that a base hand helps, so 0:15:50.600 --> 0:15:52.320 they won't do the things you need to do, like 0:15:52.360 --> 0:15:55.120 where the hats or the UV shirts or the suntan 0:15:55.480 --> 0:15:59.080 or sunscreen, or stay out longer, and so it ends 0:15:59.160 --> 0:16:00.760 up being even worse for you because you think you 0:16:00.800 --> 0:16:04.560 have this protective layer of brown. Yeah. That's one thing 0:16:04.600 --> 0:16:07.040 that um, that kept coming up in the research is 0:16:07.080 --> 0:16:09.920 that we have a lot of stuff to protect ourselves 0:16:09.920 --> 0:16:11.680 and it can be made better, and people are at 0:16:11.800 --> 0:16:14.480 work right now trying to improve the things that protect 0:16:14.560 --> 0:16:18.760 us from the sun, but that most people aren't using 0:16:18.800 --> 0:16:24.320 them right or don't understand the reality of the situation, 0:16:24.720 --> 0:16:27.840 which is Sun's gonna mess you up pretty good. All right, 0:16:27.880 --> 0:16:30.400 Well that's coming up in a sec Um. We've talked 0:16:30.440 --> 0:16:34.800 about sun tan, right, so now let's talk about sunburn. Uh. 0:16:34.920 --> 0:16:40.640 Sunburn kind of simply put is literally cellular damage from 0:16:40.760 --> 0:16:47.560 ultra violet radiation. Uh. It's called um erythema or arithema. 0:16:47.680 --> 0:16:50.200 It's the reddening of the skin, and it is this 0:16:50.320 --> 0:16:53.840 delayed reddening of the skin caused by an increase of 0:16:53.880 --> 0:16:57.320 blood flow to that area. Yeah. And the reason why 0:16:57.360 --> 0:16:59.320 you have increased blood flow to the area is because 0:16:59.360 --> 0:17:04.760 you've so damaged your skin on a molecular level that 0:17:04.920 --> 0:17:08.520 your immune response has been set off and blood is 0:17:08.600 --> 0:17:12.040 rushing to the area to bring in white blood cells 0:17:12.080 --> 0:17:14.960 and other helper immune cells to try to repair the 0:17:15.040 --> 0:17:19.040 damage you just did from letting yourself get a sunburned 0:17:19.400 --> 0:17:22.479 from uv B rays. And if you've ever had like 0:17:22.640 --> 0:17:24.879 a red, like to check and see if your sunburn. 0:17:24.960 --> 0:17:26.879 You look at your red skin, you touch it, it 0:17:26.920 --> 0:17:29.600 turns white, then goes back red real quick. It turns 0:17:29.640 --> 0:17:34.120 white because you momentarily disrupt those capillaries and then they 0:17:34.119 --> 0:17:37.600 immediately go, no, we need to send blood there, and 0:17:37.640 --> 0:17:40.320 then the red just comes rushing back. And there's no 0:17:40.440 --> 0:17:44.440 worse feeling than a bad sunburned. No, it's pretty bad. 0:17:44.520 --> 0:17:48.160 It ruins your beach trip. If you get that thing 0:17:48.200 --> 0:17:51.120 on the first day, everybody gets mad at you. You're screwed. 0:17:52.040 --> 0:17:53.800 It's just no good. It's no good. It's no good. 0:17:54.000 --> 0:17:56.840 It doesn't turn to tan. I don't care who you are. 0:17:57.119 --> 0:17:59.920 That is not science. That's a myth. It is a myth. 0:18:00.520 --> 0:18:02.720 So um, people like, now you don't know my skin 0:18:02.920 --> 0:18:05.840 it turns to dead, right, No, it doesn't. It's wrong. 0:18:06.640 --> 0:18:09.520 There is a lot of folklore surrounding sun tan and 0:18:09.560 --> 0:18:11.800 sunburns and stuff. Well, I think because people think they 0:18:11.880 --> 0:18:14.679 just like, I know my body and my skin. It's like, no, 0:18:14.960 --> 0:18:18.760 there's science that supersedes all that, right, But I think 0:18:18.800 --> 0:18:22.480 the reason that there is so much myth and folklore 0:18:22.600 --> 0:18:27.000 around UM, sun tans and some burns is because science 0:18:27.040 --> 0:18:29.320 really kind of dropped the ball for a while and 0:18:29.400 --> 0:18:32.280 didn't really investigate this. There are only now starting to 0:18:32.320 --> 0:18:36.840 investigate it on a like a really legitimate level. Yeah, 0:18:37.119 --> 0:18:40.560 you know, it's a good point. So, I mean it's 0:18:40.640 --> 0:18:44.800 kind of science is fault. Uh. And like you said before, 0:18:44.920 --> 0:18:48.560 any skin can get burned, Any part of the body 0:18:48.600 --> 0:18:52.400 can get burned, UM if it sees if the sunlight 0:18:52.440 --> 0:18:55.760 can touch it, even through clothing, which we'll talk about 0:18:55.800 --> 0:18:59.400 a bit later. To UM, you will get sunburned. Yeah, 0:18:59.440 --> 0:19:01.800 that's another too. You might think. While I'm wearing a shirt, 0:19:02.000 --> 0:19:06.639 most shirts, unless it's specifically designed to protect against UV radiation, 0:19:07.320 --> 0:19:10.879 is letting u V through UM. And as you can 0:19:10.920 --> 0:19:13.520 get burned, you can get tanned, you can get wrinkled, 0:19:13.560 --> 0:19:19.359 you can cause cellular damage. UM, anytime UV radiation comes 0:19:19.359 --> 0:19:22.000 in contact with your skin. And from what I saw, 0:19:22.040 --> 0:19:26.560 the UVB radiation is the usually the likeliest culprit when 0:19:26.600 --> 0:19:30.280 you get skin cancer because it goes in there and 0:19:30.359 --> 0:19:34.920 directly knocks around d N A d NA, it turns 0:19:34.920 --> 0:19:38.680 out actually is pretty good at absorbing energy and releasing 0:19:38.760 --> 0:19:42.199 or absorbing radiation and releasing it as heat energy, just 0:19:42.240 --> 0:19:46.600 like melanin is as well. But every once in a 0:19:46.640 --> 0:19:49.840 while it gets excited and it gets kind of knocked 0:19:49.840 --> 0:19:52.720 out of whack and some of its base pairs fused together, 0:19:53.320 --> 0:19:56.400 what we call a mutation. And if that base pair 0:19:56.440 --> 0:19:59.679 gets fused and isn't repaired, and it happens to be 0:19:59.720 --> 0:20:02.760 at a sight that say, expresses a protein that protects 0:20:02.800 --> 0:20:06.359 against tumors, well then you can get skin cancer. And 0:20:06.400 --> 0:20:11.080 that's how it happens. And even though that happens, that 0:20:11.720 --> 0:20:14.400 the base pairs fused together and aren't repaired, out of 0:20:14.680 --> 0:20:17.840 maybe one out of every thousand times, that's one out 0:20:17.840 --> 0:20:21.080 of every thousand interactions with a photon. Think of how 0:20:21.160 --> 0:20:24.560 many photons are barreling down at you over a given 0:20:24.640 --> 0:20:30.960 minute of exposure to sunlight. The odds are against you. Agreed. Uh. 0:20:31.000 --> 0:20:33.720 And you know, since you mentioned the UV clothing or 0:20:33.880 --> 0:20:40.960 SPF clothing, Ah, they are pretty great. Like most people 0:20:41.000 --> 0:20:44.520 I know now wear those shirts, Um, well they look cool. 0:20:44.800 --> 0:20:47.760 Well I wear one of those now because it's sort 0:20:47.840 --> 0:20:51.439 of three purposes, looks kind of cool. Um. I hate 0:20:52.040 --> 0:20:55.199 applying sunscreen, like all over my body. I'll hit my 0:20:55.280 --> 0:20:59.320 face and arms and stuff, but like getting putting all 0:20:59.320 --> 0:21:02.000 over my chest and belly and back and all. It's 0:21:02.040 --> 0:21:06.560 just I'm you're gonna miss spots and have weird streaks 0:21:06.600 --> 0:21:09.080 of sunburn here and there where you missed it, and 0:21:09.080 --> 0:21:12.040 it's just no good. Uh. And then third, you know, 0:21:12.080 --> 0:21:16.800 when you have some extra pounds, it's like, well, if 0:21:16.800 --> 0:21:19.560 you wear the T shirt in the pool, everybody knows 0:21:19.600 --> 0:21:21.560 it's not a good look, but you can get away 0:21:21.600 --> 0:21:24.400 with the the SPF shirt. I think that is one 0:21:24.440 --> 0:21:29.080 reason why SPF shirts were adopted. Oh sure, yeah, yeah, 0:21:29.119 --> 0:21:32.359 but they really work great, um, and they dry super quick, 0:21:32.440 --> 0:21:35.600 like my skinny friends use them, you know. But it's 0:21:35.640 --> 0:21:39.679 good for fat dudes too. But they are rated up 0:21:39.720 --> 0:21:43.000 to like fifty plus. The tighter the weave, the better. 0:21:43.080 --> 0:21:44.640 They say. To hold a shirt up to the light, 0:21:44.920 --> 0:21:48.160 like just a regular shirt will work. Like Denham, they said, 0:21:48.160 --> 0:21:49.840 it's one of the best things because it's such a 0:21:49.840 --> 0:21:57.840 tight weeks put on that Denham tuxedo and you're all set. Um. 0:21:57.840 --> 0:22:01.199 But a UPF rating they go from about fifteen to fifty. Uh. 0:22:01.320 --> 0:22:02.440 If you can hold it up to the light and 0:22:02.440 --> 0:22:04.880 not see anything, the darker the better. It's like mine 0:22:04.960 --> 0:22:08.800 is like gray and black, and um, some of them 0:22:09.240 --> 0:22:12.480 or even have or even treated I think, yeah, that's 0:22:12.480 --> 0:22:14.199 what I thought. So some of them are just the 0:22:14.280 --> 0:22:17.680 weave is so tight, ye, sunlight light can't penetrate it. 0:22:17.760 --> 0:22:20.639 Just it's a physical barrier to the UVB. What do 0:22:20.720 --> 0:22:23.400 they treat some of them with? I'm not exactly sure. 0:22:23.480 --> 0:22:26.320 That's the one thing that I'm kind of sketchy about 0:22:26.359 --> 0:22:29.200 because I don't love like I try to not use 0:22:29.280 --> 0:22:31.680 harmful chemicals as much as possible, So I don't know 0:22:31.760 --> 0:22:37.200 if those are like soaked in like carcinogenic. Probably not right, Yeah, 0:22:37.320 --> 0:22:40.720 probably not. It's probably magic dust of some story. But 0:22:41.280 --> 0:22:44.760 this woman who was uh I think she's a director 0:22:45.800 --> 0:22:48.680 of dermatology at Mount Sinai Medical Center in New York, 0:22:48.720 --> 0:22:51.919 says that clothing is a single most effective form of 0:22:51.960 --> 0:22:54.919 sun protection, even more than sunscreen, kind of for the 0:22:54.920 --> 0:22:59.760 reasons I mentioned. Because it's complete coverage. I've got a 0:22:59.760 --> 0:23:02.679 long sleeve one too, so um, it's just nice. I 0:23:02.720 --> 0:23:04.200 throw it on, don't have to worry about all the 0:23:04.280 --> 0:23:08.720 sunscreen junk, and then my legs. I usually don't get 0:23:08.720 --> 0:23:12.119 a ton of sun exposure to my legs, like I 0:23:12.160 --> 0:23:16.359 guess because you're usually vertical in a pool, like I 0:23:16.400 --> 0:23:20.400 don't lay around on a float. Uh, and it's underwater, Well, 0:23:20.640 --> 0:23:23.719 you you want to be careful, you v Radiation can 0:23:23.760 --> 0:23:26.639 penetrate up to a foot underwater. Yeah, for sure. But 0:23:26.760 --> 0:23:29.119 I mean like, I don't wear any sunscreen on my legs, 0:23:29.200 --> 0:23:31.199 and you know I've got my pants off. Look at 0:23:31.240 --> 0:23:34.359 them I've got They're pretty white. I have um flip 0:23:34.359 --> 0:23:37.440 flap tan lines on my the tops of my feet. 0:23:38.359 --> 0:23:41.119 I kind of forgot about the tops of feet, dude. 0:23:41.160 --> 0:23:44.200 I am religious about putting sun block on the tops 0:23:44.200 --> 0:23:46.280 of my feet, and I still got tan lines. I 0:23:46.320 --> 0:23:50.240 saw a kid once, Um, his feet turned into like 0:23:50.280 --> 0:23:53.159 Fred Flintstone's feet because he got burned on the tops 0:23:53.200 --> 0:23:57.680 of them. Except for those never happening to me, the 0:23:57.720 --> 0:24:00.679 whole foot. Well, they say the tops of feet like 0:24:00.840 --> 0:24:04.719 the tops of your ears and earlobes. Um, did you 0:24:04.760 --> 0:24:07.520 say the eyeballs can burn the back of the neck 0:24:07.760 --> 0:24:10.600 and those are some of the areas that are you're 0:24:10.720 --> 0:24:15.000
