Why is sweating an important physiological process in controlling body temperature?

It is a scientific law that the surface from which any liquid evaporates is cooled. When you are exerting physical effort, you become heated. Then you sweat. The sweat evaporates, leaving your skin cooled. The amount of humidity combined the the speed of the wind determine the rate at which your sweat evaporates. The faster your sweat evaporates, the faster you are cooled. So if you are engaged in hard physical activity in a very humid environment where there is little wind, your sweat will be slow to evaporate, you will experience a very slow rate of cooling, and you may experience heat exhaustion. Of course, the opposite is also true.

Why is sweating an important physiological process in controlling body temperature?
It allows the body to cool off and maintain its regular working temperature of around 36.9 centigrade. The hotter we get, the redder we get - blood is circulating more than need be. We'd overheat with the consequential exposure to blood vessels, arteries, etc enlarging to dangerous proportions.
Reply:When the body temperature rises, the hypothalamus gland detects the rise and a number of changes take place to try and decrease the temperature.


One of these is the glands all over the body produce sweat. This evaporates off the skin and, as it takes energy to evaporate, it cools the surface. This is known as the latent heat of vapourisation, whereby evaporation from a surface leaves the surface cooler than it was previously.


However, the body also has other features: The hairs all lie flat on the surface and the blood vessels below the surface dilate and allow blood to flow close to the skin to cool it.


Hope this was helpful :)
Reply:Because, when water evaporates, it cools the surface it was in.
Reply:When you sweat droplets of a salt/water solution form on your skin. This effectively increases the surface area of your body enabling heat to be dispersed more quickly. Especially if a breeze is present.
