Why do we have to wear sunscreen? - Kevin P. Boyd

View full lesson: ed.ted.com/less...
You already know that a trip to the beach can give you a nasty sunburn, but the nitty gritty of sun safety is actually much more complex. Wrinkle-causing UVA rays and burn-inducing UVB's can pose a serious risk to your health (and good looks). So what can you do? Kevin P. Boyd makes the case to slap on some physical or chemical SPF daily.

[@C_Corpze]

I wish there was a type of sunscreen that you didn't have to apply but could just consume like a pill. The sunscreen always gets washed off when I go swimming and I burn very rapidly before even realizing it. Just imagine a type of sun screen that you could take in as a pill and just works for a few hours by making certain chemicals circulate through your blood to your skin.

[@saramorris6686]

While this would be nice, there are a lot of hurdles to this. Sunscreen behaves like a barrier, so any sun protection would need to involve an even distribution of protection across the skin (plus the thicker the barrier the better), and I don't think that a pill could effectively dissipate across even the dermis to absorb UVA. Otherwise, I would imagine sunscreen chemicals would inevitably be absorbed anywhere throughout the body (not just the skin layers), and excessive amounts (which could give the best sunscreen protection) would be poisonous if it was in our bodies. Well, maybe if they were small doses that can be directed to deposit near the skin layers that fortifies the skin barrier (preferably the epidermis) over time, maybe a sunscreen pill that absorbed UVA and UVB rays could work? I think burning would still occur to some extent, though, and much like how sunscreens go through a lot of rigorous testing before getting onto shelves, this would probably require much more time.

This might be because you guys are super used to it also if you guys have a lot of melanin then you’ll less likely have a chance to get sunburn

[@Rriez15]

It’s probably because you guys aren’t Caucasian and have different genes

[@thanhdohuu9473]

It's a result of natural selection. Specifically, overtime, people lives in areas with high amount of sunlight evolve to have more melanin in there skin, which helps protect their skin against UV rays but also makes them look darker. People live in regions that lack sunlight, on the other hand, evolve to have lighter skins for the opposite reason, to absorb as much sunlight as possible. Skin tone natural selection happens a lot faster than other evolutions, especially in regions with high selection pressure and can take as little as 100 generations. It also explains why Australia and New Zealand have among the highest skin cancer rate in the world, even after taking age into consideration, as majority of their population descended from Europe from around 100 years ago and majority have relatively light skin tone that make them vulnerable to skin cancer.

[@martingl1867]

You're doing everything right. In fact, no one should ever use sunscreen, it prevents you from building your solar callus and producing the Vit D hormone in your body, which in fact, low levels of it are tied to all types of cancers. What everybody should understand is that the way they are built, correlates to a specific latitude in the world, that means, the way your skin is should be tied to the max UV index of that particular place. People is more afraid of the sun than ever before, and sunscreen use and profits are in an all time high. You know what's also in an all time high? Melanoma rates. How can this possibly be? We now live in a toxic blue light world, out of circadian order, avoiding the sun, there's your answer.

[@stephenanthonycross323]

Modern sunscreen chemicals DO NOT break down when exposed to Ultraviolet Rays! The word to look for on the bottle is “Photostable”, this means that the filter chemicals retain their protective ability without being broken down by Ultraviolet Radiation. In Europe we are far ahead of the USA when it comes to sun protection products, it is estimated that at least 30% of sun protection products sold in the USA are next to useless because the filters they contain do not do the job that they should do. People in the US still think a “tan” is healthy when it really is our skin screaming “please stop you are killing me!”. No tan is healthy!

I'm sorry, but this is the first ted talk where I didn't learn anything. It read like an advertisement for sunscreen. So... The real question I have for you is: why did we not wear this for thousands of years only to suddenly need it NOW? I would be truly appreciative to have an accurate answer to this.

[@anieee96]

Just a thought, but the average life expectancy in the last thousands of years was very low compared to today. Most people didn’t grow old enough to die from cancers in general, they’d die from bacterial infections prior to the discovery of penicillin, dehydration from diarrhoea or just lack of access to food and water during droughts etc. The same thing is seen today in developed world vs ‘third world’ countries, where in the former people tend to die from age or lifestyle dependent diseases such as CHD, cancer, diabetes etc, and in the latter from largely treatable communicable diseases (and even childbirth).

[@therobin980]

It's not that we didn't need it back then. It's just that we only fairly recently discovered that sun exposure causes faster aging or even cancer. So sunscreen is one solution to deal with that. Additionally, life expectancy was much shorter, people died of other things before they got skin cancer

[@nairbdelrey1561]

Well most died at 50, skin damage is accumulated through your life, we have clear data that it causes premature skin aging and age spots and that cant be refuted, people back in the day and a bunch of people of old age now days look terrible skin wise because of this. Being super wrinkly is not normal if your protected your skin diligently

[@satire9298]

I love how people are being defensive. Some are even claiming that sunscreen is harmful. It's like those people who claim brushing 3 times a day is too harsh on your teeth, or that physical exercise does more harm than good over a long period of time. So you prefer the taste of white sugar over sugar substitute. It's okay! We get it. You're human. You have some bad habits. Feel free to order a regular soda rather than diet soda. Just please stop with the pseudoscience and conspiracy theories!

[@MalaysianTropikfusion]

I'm sorry, I don't have any scientific proof to back my claims. I'm generalising, based on the few Malaysian/Bornean/Filipino/Indonesian islanders/fishermen that I know or have met. They don't use sunscreen, are really tan, don't get skin cancer, and usually die of old age or other diseases, but not cancer. Their tan skin doesn't exactly make them as vulnerable to it as fair-skinned people. What I was trying to say is not everyone needs sunscreen lotion.

Can you still be affected by UVA rays when you're out in the sun during winter?

[@alenapham2875]

+EndErPuppy Yes, there is UVA present all seasons, all weather. UVA passes through clouds, so even when it is overcast, you still need sunscreen. Temperature does not affect this. Look for sunscreen labeled Broad Spectrum or has a PA rating. The highest PA rating is PA++++, so aim for that. A good thing to know is that if you are wearing a chemical sunscreen, those two hours before reapplication are two hours of sun exposure. So, if you apply your chemical sunscreen at 8 AM, stay inside until 10 AM, you do not need to reapply. Physical sunscreen does not deteriorate like chemical does, but it can be rubbed off easily.

[@howudoin62]

a completely new kind of sunscreen that lasts more than a month could be based on a thing like transparent Henna. A chemical at henna does a Michael reaction with the keratin protein of skin and links a colored molecule to it durably, not washing off. There are molecules that do the Michael reaction that are transparent. Linking that michael reaction group to a UV absorber then makes a sunscreen that lasts longer than a month. This could be a completely new anti-photoaging product as a new revenue product. Notably, the UV absorbers in commercial sunscreens last only a few hours, but, fortunately, the UV absorbers in printing inks lasts months. Those chemicls could be tested to find out which are body harmless, and be a part of the michael reaction sunscreen that lasts longer than a month.

the only problem is you still need the sun without sunscreen to get vitamin D which helps prevent against canser and the chemicals used in sunscreen are not very good for you and should only be used when your going out for a long pie rod of time

[@marihumanisa7803]

actually sunscreen doesn't block the absorption of vitamin d so its fine to use

Even still with all the cloud cover, UV rays are still able to hit your skin.

[@samanthagarcia1398]

what I don't understand, is how non-modern humans survived and thrived without sunscreen if they faced the same conditions as today. I don't say ancient humans, because I mean the sapiens who had the same lack of full-body hair coverage as contemporary. what were their methods of keeping out of the sun? were those forced to work in the daylight hours unprotected more susceptible to cancers?

[@anieee96]

My theory is most didn’t grow old enough to develop cancers, the average life expectancy was pretty low compared to today. I guess bacterial infections and drought were more of an inherent threat than prolonged sun exposure… but very interesting question, wish they’d have explored it

[@shuasee3957]

Perhaps, the rays of the sun are now more intense due to the fact that our atmosphere has deteriorated and weakened over the past centuries of industrialization. Check out global warming...

[@nairbdelrey1561]

Thrive? They all looked terrible in their 50s age spots and wrinkles everywhere

[@eyeoftruth4405]

Darker people easily thrived, considering ancient humans were mostly dark. Australia/Newzealand has the highest skin cancer rate in the world, yet the natives thrived there for almost 40k years without sunscream.

I like how they say you shouldn't go outside between 10 AM and 4 PM...Really!? I mean are they actually serious about that? That is the whole day! I understand that this video is supposed to teach the viewer the dangers of the sun, but with giving overzealous rules and harsh consequences, they are doing the opposite. People are smart and will rebel against you if you do that. You can see it in the comments already.

Having basal cell carcinoma a dozen times I would use Sun screen when golfing. Was ok for first 14 holes until sunscreen leaked into my eyes and affected my play. Not a problem for recreational golf, but huge problem for amateur PGA rounds. As a result, hardly golf anymore.

Sunscreen is like of all in one treatment for me in skincare. I don't need to buy different treatment products anymore. Sunscreen is good in long term use.

I came here expecting to learn why humans, despite having had to deal with the effect of the sun since our ancestors first crawled out of the sea, isn't naturally equipped to deal with it. Instead I got a sunscreen commercial. I am disappointed.

[@TheJurnalyst]

EVEN MADSEN sorry, maybe your ancestors crawled out of the water, but mine didn't (which would explain why we have melanin and y'all don't).

[@MrFwufyClipsHD]

+TheJurnalyst please leave the internet thanks

[@philinator71]

Humans are naturally resistant to the sun. Depending on where you live of course and your ethnic background. Melanin is what protect our skin from sun damage and is what makes the skin brown. European are more likely to get sunburnt because they have fairer skin and have less melanin due to the climate since Europe, especially in the north does not have much sun. Therefore melanin isn't needed. Where as it's the oposite for Africans for example. It is also why people get darker after sun exposure as this is the body trying to adapt to the change.

[@AiNaKa]

TheJurnalyst well you're kinda being ignorant and racist there.

[@robbieh6182]

EVEN MADSEN because increased sun protection also means decreased Vitamin D production. A dark skinned person living far away from the equator will have a vitamin D deficiency. Vitamin D deficiency weakens the immune system, therefore in our past when diseases were more widespread, there was a strong selective pressure for light skin near the north and south poles. Skin cancer has mainly become an issue in modern times with people living areas that they aren't adapted to. That's why sunscreen is so important now, but less so in the past. Also we are living longer and thus have a longer time to accumulate sun damage. Hope this answers your question.

If you sunbathe with sunscreen you WILL get darker(supposedly even in a more fairer and longer lasting way), less than without but you will. plus, consider that without sunscreen you my get burnt so much that your skin will peel off in which case you'll be paler than before

Through living in tropical region, I always struggle with this doubt whether I should use sunscreen for protecting from strong sunburn or should refrain from using it that contains lots of chemical substances that cause our skin really dry situation.hah

[@rylans.5365]

The chemicals in sunscreen aren’t harmful on your skin, it’s harmful if you eat it

[@Ruktiet]

Good point. Humans have evolved hundreds of thousands of years WITHOUT sunscreen and no generation failed to reproduce. Now, suddenly, we get melanomas like never before. Draw your conclusions. Live naturally and avoid these know-it-all “scientists” who completely deny nature.

[@Tasia87]

Do some research for a healthy sun screen. Try applying moisturizer like Cerave before sun screen if youre dry.

[@Messerschmitt2211]

How about applying the sunscreen on the car's window surface, instead of our skin? Will it work? Hahaha lol

You forgot to look for a sunscreen that protects from both UV A and UV B, some sunscreen only protects from the burning

He said “broad spectrum”, which means UVA and UVB.
