When the temperatures are soaring, and the body needs to cool down, tiny glands in the skin, produce a salty liquid, which we call sweat. An average person has 2.6 million sweat glands in his skin !! The sweat from these glands spreads over the warm skin and evaporates, causing the body to cool down. In the process, some waste is also removed from the body. Sweating is a natural and essential process which regulates the body's temperature and removes waste products.
Recently, researchers have found that sweat plays another important role. They have found that sweat contains a natural antibiotic, which may keep skin-dwelling bacteria from multiplying. Researchers have called this substance – dermicidin.
In fact, our skin is occupied by numerous bacteria which thrive on the wastes secreted by the body. Whenever there is a cut or a wound, these bacteria enter through the skin into the body to cause disease. Dermicidin is the first antibiotic found, which is permanently produced by cells in the human skin and which can kill varied types of bacteria found on the skin-- this means that it provides a constant protection against invading microorganisms,.
By limiting the bacteria on the skin, dermicidin is probably the first line of defence against disease causing bacteria.
