That means UV exposure outdoors is worse now than it used to be.
Unfortunately, it seems nobody measured UV at ground level before we started destroying the ozone layer, but there are barely any historical accounts of serious sunburn before ~1930. Everyone just talks of heat stroke and dehydration rather than actual burning/peeling of the skin.

People in Europe and North America generally wore hats and long sleeved clothing before the 1900's. Sun tanning is a modern phenomenon.
People would also not be out very much during the heat of the day. Even going back to ancient farmers.
Nothing long sleeves and a bucket hat won't solve
