Sweat must evaporate to have a cooling affect

Splet07. dec. 2016 · But when sweat simply drips off you and hits the floor, it can't lower your body temperature. To reap the cooling effect of sweat, though, that salty liquid must evaporate off the skin... Splet11. okt. 2011 · On dry days, sweat evaporates quickly, which means it also carries away heat faster. On humid days, when the air is already saturated with water, sweat evaporates more slowly. This explains why it feels so much hotter in high humidity. When relative humidity reaches a high enough level, the body’s natural cooling system simply can’t work.
