A Wonderleaf question
Why do we sweat?
a real page from the book
We sweat to keep the body from getting too hot. When exercise, sun, or a warm room raises your temperature, glands in the skin release salty water. As that water dries into the air, it carries heat away and helps your organs stay in their working range.
A delightful detail: the cooling happens mostly after the drops leave you. Evaporation takes energy from warm skin; wave a damp hand and you can feel that missing warmth. That is why a breeze can make a sweaty child suddenly feel cooler.
