Answer 1

You often hear people say “it isn’t the heat, it’s the humidity” The reason why is because higher humidity limits the ability of sweat to evaporate. In the Gulf Coast states you can be sweating like crazy, completely drenched with sweat dripping off you because it won’t evaporate. In a more dry area you’re sweating just as much, but it’s evaporating much faster so you feel cooler
