due to cooling cause by evaporation

Answer 2

Heya!!!

When any liquid evaporates,  it cools the remaining liquid, and the vessel containing the liquid. 

Moving air allows sweat to evaporate off of our skin, thereby cooling it. Not only does this produce a cooling effect on our skin, it actually helps to keep our body temperature low. ...
