alt Hacker NewsIt’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.

I don't know of anyone using sunscreen from the moment they wake up until they go to sleep. Guaranteed that even the best user will still receive a healthy amount of UV even if they refresh every few hours. As far as I'm concerned sunscreen is a 10am-5pm endeavor, not needed before or after

Sunscreen isn't a 100% block, though. In fact it's advertised by what proportion of the UV it blocks. And in general it's far more common to have too much sun exposure than too little, and in the areas where people have too little, it's not exactly the norm to wear sunscreen every time you step outside.
