Some sweat, others glisten either way it can happen at the most inopportune times. But the bottom line, according to dailyglow.com, is sweating is actually an essential part of every person's physiology. Read on to find out why its good for, and how to tell if you sweat too much.

What is sweat? Mostly water and salt, with small amounts of other substances, including minerals and electrolytes.

Does sweat detox the body? Nope, detoxing is the livers job.

Where does sweat come from? From the the 2 million and 4 million sweat glands spread over the entire body. While armpits have one of the highest concentrations, the glands are actually everywhere including the soles of the feet and the palms of the hands. Two types of sweat glands are involved in perspiring. Eccrine glands, which respond to heat, are located just about everywhere on the body; they release an essentially odorless sweat directly onto the skin to cool the body. Apocrine glands develop in hair follicles - on the scalp and in armpits, for example - and they respond to heightened emotions as well as to heat. They release a fatty sweat thats broken down by bacteria on the skin, in a process that produces a stink.

Why do we sweat? Sweat glands are activated when the body gets hot or a person is experiencing stress. The sweat glands are under the control of the nervous system, says Dr. Cameron Rokhsar, who is also the medical director of the New York Cosmetic, Skin and Laser Surgery Center. So you can sweat when youre in a flight-or-fight situation and become upset or angry, just as you do when you become hot, such as when youre exercising.
