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…

Pro golfers look a good 10-20 years older than their real age sometimes fwiw. In contrast to most other pro athletes in indoor disciplines who generally look better than their age. There's also examples of truckers who spent most of their career with the window rolled down and you can tell straight up what side of the road they drove on.

Truckers, plural? Is there an example that isn’t William McElligott from the famous photo[1]?

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.

Those drivers don't even need to have the window rolled down as far as I know. That's because most door auto glass lets UVA rays through and that's what causes premature aging. If you want to block those UVA rays, you would need to apply some kind of additional film to the side window.

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.

So everything in moderation? Cool, glad my philosophy still applies.

Extreme tension leads to breakage. Something something in buddhism about not trying to put too much tension in a bow or it'll break.

Also known as the middle way.

Moderation is a great philosophy.

Earlier quoted context omitted.

That's basically sun up to sun down, here. It's been completely grey, overcast, and raining here all day and the UV index sat between 3 and 5.

The worst sunburn I ever got was on a boat while overcast. I don't trust them clouds no more.

Clouds block a decent amount of UV on average, but it’s much less consistent than you might expect. 9/10 you might be completely fine with no sunscreen and then get a horrible sunburn the tenth, with no apparent visual distinction between them.

Denver, CO, USA resident here -- this looks _super_ useful and I'm likely to start using it heavily. Our weather here is usually very outside-encouraging (if getting hotter over the years) and our UV is _ridiculous_; I see the index hit 11 and 12 with some regularity. Thanks for the link!
