People didn't used to expose themselves to as much direct sun and covered themselves with a lot more clothes. Traditional clothing in arid sunny areas typically covers everything, look at people in the middle east today.

I live in a very sunny desert area and it's kind of funny when people assume people from here would be "more tanned". We stay in the shade, the sun will kill you! Anyone working outside is wearing wide brimmed hats and typically has all of their skin covered with clothing even in the heat, people typically have their faces covered with cloth as well.

Spending time outside with minimal clothing in direct midday sun is a modern weird behavior.

Yup, I grew up in a hot subtropical climate and the best counter to the summer was to stay indoors, hydrate. If you have to be outdoors, stay in the shade, if you have to be exposed to the sun, cover yourself. All of the benefits you get from being in direct sunlight can be gained with just being outdoors in shaded areas, maybe for a slightly longer time.

The way western culture glorifies direct exposure to the sun is always hilarious to me, everyone lining up to burn their skin for hours on end to "catch up" on sunlight exposure. Instead of just playing an outdoor sport under some trees or being outdoors in the morning/evening when sunlight is a lot less potent and weather is a lot more pleasant.

Absolutely agree.

I'm find myself aghast when I travel to different environments and observe people laying in direct sun almost naked. Not that I think they shouldn't, it's just such a stark contrast to my norm. I'll end up with a painful sunburn if I venture outside uncovered for more than 10 minutes at home.

People in greece/israel/italy/etc don't cover themselves much and they have very long lives.
