sweating

[spiderman]

how does sweating cool you down

[wildwood]

The perspiration exuded from the body is warmer than the outside temperature (generally) so cools down the skin. This is important as it cools down the underlying blood vessels so keeping the blood at the right temperature.

[Teddio]

When water evaporates it requires 2.2 million joules of heat energy per kilogram of water. Evaporation of sweat causes cooling as heat energy is absorbed from your skin. When the humidity is very high, the sweat can't evaporate and you stay hot and sticky.

[Peter Pedant]

Sweat evaporates

evaporation requires energy which comes from the body and so the body gets cooler.

I mean try an experiment

Go outside and throw a bucket of water over yourself and see if 1) you get warmer
2) you get colder
3) you stay the same
and say, I do science, yeah !

Dont do this inside !

This is your first step to becoming a physicist
