Why does the wind (from a fan, for example) feel so much more cooling/chilling when the skin has water/sweat on it?
In: Biology
Water on your skin absorbs body heat. When it evaporates, it carries that body heat away with it.
Because the wind forces the water molecules to evaporate. Since the molecules don’t already have all the energy they need to evaporate (if they did, they’d have evaporated by themselves before the wind reached them), they take the remaining energy(heat) from your skin thereby cooling your skin.
