A Wonderleaf question
Why do we sweat?
a real page from the book
We sweat to cool down. When your body gets too warm, sweat glands release salty water onto your skin. As that wetness changes into vapor, it carries heat away, helping your brain and organs stay in their working temperature range.
The neat part is how adjustable the system is. A slow walk may make only a light sheen, while running hard can soak a shirt. Your skin is covered with millions of glands, all responding to tiny temperature messages from your body.
