Earlier quoted context omitted.

And https://web.archive.org/web/20260000000000*/https://www.outs... seems to suggest 2021. I guess we'll put that above, although we had 2019 in the 2022 thread ( https://news.ycombinator.com/item?id=48715020 ) :)

It was published early 2019, maybe late 2018. Searching for the title of the article ("Is sunscreen the new margarine?") makes it easy to pinpoint: there is a open letter responding to the article, dated January 15, 2019. https://www.asds.net/Portals/0/PDF/LetterToTheEditor-Outside...

Ok, let's go with 2019!

The article seems to be a meta analysis of a bunch of conflicting research to support a narrative that we don’t really know shit. And fair, we don’t. But a couple of things we do know that weren’t covered - egregiously so - is that aging is UV damage. Sometimes called photoaging, wrinkles, sun spots, discoloration, fine lines, grey hair, all of that shit that you associate with someone visibly looking old is sun dama…

I often embarrass my daughter when she has some new friend over. If the topic comes up, I give a demonstration. I'm 62 and I've never tried to get a tan and work indoors, and I haven't had a serious sunburn in close to 40 years. On the other hand, I lived spent the last 20 years in Austin, TX. I mow the yard and I ride a bike and in the summer months I put on sunblock before doing the bike rides an sometimes mowing.

The exposed parts of my arms look like I'm 62 -- freckles, some age spots, the skin has lost a lot of elasticity. But then I roll up my T-shirt sleeve to expose my shoulder and my skin is like it was when I was 25: not just pale, but no freckles, no age spots, still supple.

Wow, it feels like nobody read the article. Findings:

- high blood pressure leads to a lot of deaths

- people that spend more time in the sun have lower blood pressure

- skin cancer is caused by sun exposure, but it kills far, far less people than high blood pressure

- people that spend more time in the sun have a lower rate of dying from skin cancer than people who spend less time in the sun!

Summary: more sun exposure makes you less likely to die on at least two fronts!

It's really very simple. You skin adapts to sunlight and doesn't burn if you increase your exposure gradually, and then you get some amazing benefits from it!

Who cares about your skin looking a little older when it prevents cardiovascular related deaths??

Does anyone know whether UVA or UVB is more conducive to producing vitamin D naturally? A quick search shows me that it is mainly UVB that's responsible for that, but unfortunately, this is what gets blocked out by glass windows and sunscreen. On the other hand, UVA is what causes early aging. So this is just an unfortunate situation because I don't think there's a way of just getting UVB into you in a safe way.

The article explains that it is much safer than not getting UVB. Nothing in this universe is completely safe, but the evidence is that getting UVB is bar far safer than not getting it

What I got from this is if we mandate the hospitals open their rooms to the sun, the new correlation will cause people to avoid the sunlight because "it leads to more deaths"

I made a small little web app calculator for myself and my family to figure out how long we could stay outside without needing sunscreen based on current UV and skin type. I use it daily in the summer and a couple thousand people use it every month also. You can check it out at https://sunburntimer.com . It's also free and open source software, github link in footer.

Looks like the weather might be a bit off, I imagine from your upstream provider. In Indianapolis, all stats look correct except it says we have thunderstorms. Couldn't be a clearer day and nothing on the radar.

I've not heard that grey hair is sun damage. Do you have any sources for that?

If you compare President Obama photos (2008) to President Obama photos (2016) you may conclude that he spent most of his time lounging on the beach?
