why do we sweat more in humid weather?
In: 0
Humans dump heat by sweating. Sweat evaporates into the air to cool us off. When people get hot, they sweat.
In humid air, the air has less capacity to accept more water. So sweat does not evaporate efficiently. It’s actually entirely possible for it to be too hot and humid for a person to lose heat at all by sweating, about 95F/35C with 100% humidity(and this is in ideal conditions in theory, it is totally possible to have deadly heat waves bellow this temperature because real world conditions do not mirror the theoretical physical limits).
So in humid temps, it’s harder to lose heat by sweating, which warms a person up, which causes them to sweat more to try and lose more heat.
