How do sweat glands work?

The nervous system and body hormones combine forces to regulate and control sweat glands, which are placed virtually all over the body under the skin surface. The sweat glands have evolved as a primary cooling method for humans. Increased physical activity causes human body temperature to increase and people do not have a mechanism such as gasping for breath that helps in cooling. Instead, the body relies on sweat glands to secrete a clear, potentially inflamed substance to the skin surface to reduce the body temperature.

sweat glands work by secreting a substance consisting mainly of water, sodium chloride and electrolytes. The sweat, also called sweating, is produced by the gland and then selected to the surface of the skin over a small tube leading to the pore. The pore is an opening on the surface of the skin and the human body has thousands of pores that escape the sweat.

Ecrine sweat glands are by far the most common in the hum and exist only in primates. They are found almost all over the body and developed in conjunction with the development of hairless skin in humans. These sweat glands are found in the highest concentrations on the scalp, feet of the legs and palms of the hands.

Apocrine sweat glands are found in channels where there are hair follicles, so they are found in areas such as armpits and hair. They begin to secrete around puberty and secretion can be overcast as a normal sweat. It is known that these secretions contain pheromones, which are chemicals that can change hormonal balance in other people. The exact relationship between the apocrine sweat glands and their influence on the hormones in the body is not entirely known.

There are other glands that are similar to sweat glands, but eliminate very different substances. The mammary glands are considered to be a sweat gland that produces milk. Ceruminous glands are placed in the ear and produce ear wax.

Excessive sweating can lead to dehydration. Eccrin gland can with extreme exertion or heaty bodies excrete over three liters of fluid per hour. Therefore, it is vital to replenish these fluids as soon as possible. In addition, electrolytes from the plasma of the body can be removed during intensive sweating episodes. Anyone who is abundantly sweating for a long time must replenish water and electrolytes, usually through drinks supplemented by electrolytes.
