Don’t you feel little COOL after sweat, though smelled badly?

Your body perspires, or sweats, to COOL itself off. It is also another way for your body to get rid of wastes. Each day, your body makes heat as it burns fuel or food, for energy. When this heat causes the temperature of your blood to rise, the cooling center of your brain goes to work.

First, your body slows down the burning of fuel. Then the blood vessels in your skin widen. This allows more blood to flow. More it flows, more the heat that is given off through the skin. At the same time, the sweat glands that are in your skin make more sweat. Sweat is made mostly of water and a bit of salt and waste. When sweat hits the skin, it begins to evaporate or change into a mist in the air. This evaporation process also helps to cool your body.
