This simple fluid is vital to the maintenance of healthy tissues and normal organ function. When we do not consume enough water, the cells will pull fluid from the bloodstream, and, in turn, causes our vital organs to work harder. This puts a great strain on the kidneys, which function to purify the blood and rid the body of toxins. Heat is lost from the body in several ways.
Humans lose heat mainly through their skin.
The skin acts much like a radiator in an automobile. When air hits the skin, more heat is lost through a process called convection. Heat can also be lost through a process called conduction. This occurs when the skin comes in contact with a cooler object or substance, like the pavement, or water. The largest heat loss from the skin is through evaporation.
