Penn State researchers found that the maximum wet-bulb temperature humans can endure is lower than previously thought — about 31°C wet-bulb or 87°F at 100% humidity — even for young, healthy subjects. The temperature for older populations, who are more vulnerable to heat, is likely even lower.
so wet bulb is a 'perfect' condition between humidity and heat, we use water to cool our bodies and if humidity is high enough it nullifies the ability for sweat to cool you faster than surroundings heat you up
sahara is dry as a bone so itd need to get way hotter for your sweat to not work, or wetter. idk why wetbulbs dont seem to happen so often in jungles tho... seems ideal
Probably because it's cooler. Lots of shade, and the people that live there must know a thing or two about heat stroke or exhaustion. We have reached 35 degree wet bulbs on earth, but currently only actually on and around the Persian Gulf. Coastal areas are more at risk because of the water.
I think they say you can survive 140 degree surface temperature? if you're otherwise well hydrated and in the shade and the humidity is low. Evaporative cooling works really well if your surroundings are dry and you don't dehydrate or let your electrolyte balance go out of wack.
In jungles the humidity comes from all the plants evaporating water to do photosynthesis. That evaporation brings cooling, so jungles get pretty warm but not deadly hot. You can almost think of it that plants have to sweat to photosynthesize.
Coastal and swampy areas near the equator at the most at risk, because there’s so much water just sitting around.
