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.
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.
