I don’t understand how this is surprising for people.
We have evolved under the sun, of course we have adapted to its presence, and taking it away naïvely is unadvisable.

That said, sun bathing is a modern phenomenon. Our ancestors knew enough to assess that painful sunburns were bad and mitigated their exposure by wearing large hats and clothing with long sleeves. I'm sure even primitive peoples would cover themselves when necessary. If you spend a lot of time working outside you also develop a very dark tan which helps quite a bit. Modern people seem to suffer mostly from spending so much time indoors that even moderate sun exposure on the weekend produces a damaging sunburn.
If you don't put sunscreen on your kids, it's tantamount to abuse. (I recently experienced this walking through the woods at 10 AM with a family member, no I don't need any sunscreen for a short hike through the trees)
They either over-cautiously drink 8 bottles of water a day for dubious health benefits, or they uncaringly approach some wild animal that they cannot imagine goring to death them a few seconds later.
