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

It’s great that people are finally talking about this. It should have been obvious that sun exposure without sunscreen is needed to some extent. If you’re blocking the UV all the time, then how could you possibly be getting the minimum UV exposure that you do need. But people have become absolutely obsessed with sun protection.

tl;dr you probably should get a few minutes of sunlight daily on your unexposed skin without sunscreen for the "health gains"

(you can also wear clothes to block sun instead of sunscreen so you don't necessarily need sunscreen at all)
