Detailed explanation-1: -When the body temperature rises, the sympathetic nervous system stimulates the eccrine sweat glands to secrete water to the skin surface, where it cools the body by evaporation. Thus, eccrine sweat is an important mechanism for temperature control.

Detailed explanation-2: -Anhidrosis is a condition in which your sweat glands don’t function as they should to remove heat and cool your body down.

Detailed explanation-3: -Heat stroke occurs when sweat can’t evaporate fast enough to cool the body. Hyperhidrosis is excessive sweating. Known causes of heavy sweating include obesity, thyroid disease and diabetes.

Detailed explanation-4: -That’s because cooling your body via sweating relies on a principle of physics called “heat of vaporization.” It takes energy to evaporate sweat off of your skin, and that energy is heat. As your excess body heat is used to convert beads of sweat into vapor, you start to cool down.
