Of course, misleading clickbait title, but higher sun exposure leads to greater longevity, contrary to what you might think if worried about skin cancer.

Thanks for that. I'd been asked to find that again.

US dermatologists seem to be outliers though

In Australia they have adopted new guidelines because they were starting to see negative health consequences of extreme sun avoidance.

When I was in OZ in 2002, it had the highest rates of skin cancer in the world and was the only place where skin cancer rates were falling. Everyone was covered up except tourists. Kids in school were not allowed out for recess without a long sleeve sunshirt and a wide-brimmed hat. And, yes, it was helping a lot with skin cancer. But in recent years they have dialed that back and, controversially, created guidelines for 3-4 levels based on the color of your skin.

As they were ahead of the curve on getting skin cancer and ahead on reducing it, they were also ahead of the curve on seeing health impacts of extreme sun avoidance, especially for people with darker skin.

US derms are at thenextreme. They still officially recommend that you should apply sunscreen even on very cloudy days. It's an approach that looks at one metric - skin cancer rates - and glides over big epidemiological data sets that highlight the health cost of that approach.

As with most things, we are finding that moderation is best and the evolutionarily oldest delivery methods confer advantages that isolated supplements often don't
