Sure, you’re talking about the wet bulb temperature.
But.
You’ll find a lot of people from the northern part of the US that simply can’t function in the south in the summer, when it’s >90F. I’m a transplant from the north to the south; I’ve adapted just fine, by virtue (?!) of not having air conditioning. And it goes the other way too; if you move to a colder climate from a hotter one, you’ll eventually adapt to it.
This is not the case for all people, but most people will be able to adapt.
People become acclimatized more to a given climate, but there’s a very real scientific point at which humans - all humans - can’t cool off and will overheat and die. There’s no amount of “aw, shucks. I grew up around here. It’s not that hot” that will save a person at that stage.

Yes, as the comment you replied to already said. That is called the wet bulb temperature.
There’s adapting to warmer or colder weather, and then there’s drowning because it’s so hot and humid that the air condenses in your lungs.
I bought a steam tent. 15 minutes in it a day, while agonizing, makes being outdoors tolerable. Also my apt doesn’t get below 81 in the summer.
