I don’t know about stark naked - in the northern climes where the fairer complexioned folk roam(ed), furs and wool were a matter of survival.

Anyway, UV sucks, nobody is hurt by minimizing it and supplementing via diet. Hell, in the north the sun doesn’t even rise high enough to be a source of vit D for months on end. You have to get it from diet or not at all.
