By evaporation of the water in the perspiration. When water evaporates, heat energy is absorbed.
It is the sweat that cools you. That is your bods way of not overheating. You really need to worry when you stop sweating.
evaporation
It cools you down.
No. The body perspires to cool down and to regulate body temperature.
Sweating is your body's way of cooling down itself.
the body is trying to cool down?
underarm/armpit it is one of the part of the body that perspire much especially when you play .
Its a response from 'the body' to regulate temperature of the body.
The skin keep the body cool by sweating. When the body gets too hot as you may know by exercising you begin to perspire. This is how the body cools itself down.
When you perspire, liquid (perspiration or sweat) is secreted from your skin. When it evaporates into the air it carries small amounts of body heat with it making the body feel cooler.
Of course it is, when you perspire it is one of the body's methods of cooling down as the sweat then evaporates and causes a cooling effect. Therefore, the more effort you exert, the hotter you become and consequently the more you perspire in order to cool down. While this isn't an incredibly biological explanation I hope it still expresses that it is natural.
Perspiration coats the outside of the skin with moisture (water). The water evaporates. Evaporation requires heat to be absorbed by the water (the latent heat of vaporization). Heat is removed from the body surface to provide the water with the latent heat of vaporization.
i perspired after my PE class. it means sweat Of the various parts of the body, the underarms perspire the most.
