To add to this with an article I just found

“The [wet-bulb] temperature reading you get will actually change depending on how humid it is,” says Kristina Dahl, a climate scientist at the Union of Concerned Scientists. “That’s the real purpose, to measure how well we’ll be able to cool ourselves by sweating.”

Yes, wet bulb temp is in the context of humidity.

Apparently 95f or 35c is the "limit" for humans - where many people will have health issues if they can't cool off otherwise.

"Health issues" may be under selling it.

> The theoretical limit to human survival for more than a few hours in the shade, even with unlimited water, is a wet-bulb temperature of 35 °C
