Question

Hot and humid day is more unbearable than hot and dryday why

Answer 1

When the air is saturated with water, like on a humid day, evaporation is much slower. The air is already full of water, and can't hold much more. Your body will sweat in an attempt to cool itself, but you only end up wet and hotwithout this sweat evaporating. ... Low humidity will make the air feel cooler.
