When some of the moisture (water) in your sweat evaporates from your skin, it tends to cool your skin somewhat, as it requires energy to change from liquid on your skin to water vapor in the air.
If/When the humidity is high, like at 100%, the moisture in the sweat won’t evaporate because there is no “room” in the air for the water to go to – which can lead you to just being hot and sweaty.
Low humidity and moving air aid in sweat evaporation and in turn cooling of the skin.
This probably explains why blonde and red-headed white cavemen moved out of their home bases in Africa and migrated to more cooler climate, northern Europe.
We just got done with a “boiling sweat” heat wave/drought for the last 2 months—day after sunny day in the high 90s and no rain which is really unusual for SW PA. Our summers are quite often rainy, muggy and grey. Now it feels like Fall. Oh well I know climate change is a normal process the Earth goes through every few hundred years, but it’s an adjustment especially if you don’t have whole house air conditioning.
My Dad once went onto the roof of the hotel he was in while on a work trip, just for a bit of fresh air. When he got there, he found a guy on the roof lying on a sheet of aluminium foil, sunbathing. He assumed the foil was to allow tanning on both the top and the sides at the same time. The trouble was, he’d fallen asleep. With the (later that day) crazy heat, he had burned to the point where his skin was actually bubbling. They had to call an ambulance as he was that bad. Now that must have been really painful.

Why is he complaining? Evaporating sweat cools you down.

He should go hide at the far back of the cave and perhaps cover his skin in aloe vera or something other against the sunburn.

Just don’t go on TikTok where the idiots are falsely claiming sunscreen causes cancer. They’re a menace to humanity

I grew up in the time when we had “sun tan lotion” not “sunscreen”. I wish I’d had sunscreen, could have prevented the skin cancer.

I use a sun umbrella that’s rated UV 50. Totally blocks out the sun. You can feel the difference. It doesn’t, unfortunately, block out the humidity.

You don’t wanna be that hot.

under your skin, probably on the outside it evaporates. As soon as you invent sunscreen, it’ll be a big seller.
