>These rebels argue that what made the people with high vitamin D levels so healthy was not the vitamin itself. That was just a marker. Their vitamin D levels were high because they were getting plenty of exposure to the thing that was really responsible for their good health—that big orange ball shining down from above.

Yeah, it's not just UV. Infrared light has beneficial effects on deep tissue, including the brain. There's no way to get that from a pill.

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 expos…

That logic is extremely broken. People who spend more time outside do so because of more physical activity . The sun exposure is a side effect. Drawing the conclusion that sun exposure is therefore safe is just totally bonkers.

The study in the article controlled for that

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.

This is neat if you are avoiding the "getting red". My understanding is that the damage occurs with or without the sunburn but maybe this goes without saying.

I guess all the grandmas on the beach that look like they have a leather hide for a skin didn't get the memo that the sun doesn't cause damage after all.

In all seriousness: don't listen to OP, use sunscreen whenever possible.

Or active people spend more time outside and have a lower rate of heart disease, regardless of whether the sun is shining.

That’s not what the article said though. It had nothing to do with physical activity. Ironic considering the comment you replied to

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.

The sunny side of the road?

You are still missing the point. Leathery skin is (by current beauty standards) undesirable but avoiding sunlight is deadly. Pick your poison

He specifically mentions sunbathers. Not landscapers or construction workers

The map isn’t too far off for July[1] considering how far Australia is from the Equator[2]. My area is similar to Sydney in your map. For Denver it’s the elevation that’s exposing them to more UV rays. [1] https://www.epa.gov/sunsafety/sun-safety-monthly-average-uv-...

Yep, this—we aren’t as close to the equator, but there’s less atmosphere to filter UV. Not so much in terms of beach days, of course, so sunburns here tend to be less than full-body.

All that said: a daily mean of 13-14 is past what we’d see here—and yeah that is some serious burning.
