      Its because the water produced keeps us cool you fat mess. How do you not know this. Just give up

      the reason is it takes energy to convert liquid water into vapour, the water is changing state so this is called latent heat and this is removed from the body so it keeps us cool

      also on a humid day it's harder for the water to change into a vapour as there is so much vapour in the air already so less heat removed from the body so harder to cool down
