Sweating

Sweating is also known as perspiration, transpiration or even diaphoresis. It is secreted by the sweat gland under the skin of the mammals. It mostly consists of water and dissolved substances. Sweat contains various kinds of chemicals such as odorants(2-methylphenol and 4-methylphenol) as well as little amount of urea. The purpose of sweating is mainly to regulate the body temperature or thermoregulation. Sweating can achieve the goal of regulating the body temperature by evaporation from the skin surfaces because it has a cooling result due to the latent heat of evaporation of water. If a body move rapidly or doing exercises, sweating will be promoted due to the increase of metabolic rate and vice versa. The volume of water lost in sweat daily is highly variable, ranging from 100 to 8,000 mL/day. Sweat mainly contains of water and also minerals(like sodium, calcium, magnesium,and potassium) or even urea. Also many kinds of trace elements excreted along in the sweat such as iron, chromium, nickle and lead. The different circumstances of the internal environment will vary different composition of the sweat.

Sweating can be embarrassing, mostly because of the odor or smell came along with it, and nobody like to move around with wet clothes. However sweating should be nothing to get embarrassed about it. Usually men sweat more than women and most people would like to never sweat again. They willing to spend their money to buying up various kinds of antiperspirants, deodorants or body sprays. In fact, these should be avoided at all cost because these articles can block the pores in the skin sweat can causing cannot release the harmful toxins. Most of the deodorants contain aluminum which can makes its way into our bloodstream and eventually causing many diseases. Sweating should never be stopped because it helps to eliminate harmful toxins from the body and cleans the pores in the skin, thus helping to reduce black heads and acne. One of the advantages is that mentioned just now it can control the body temperature in hot situation and while exercising; thus it prevents one from having a heat stroke. It also prevents individual from toxins or chemicals by diluting them with sweat as they come in to contact with the skin. Some of the scientists found that sweating has smell that acts as scent. This scent sends secret signals to people around an individual. It is usually used for attracting your loved ones. Finally, sweat contains a natural antibiotic called dermicidin that helps to destroy bacteria on the skin.

Besides, sweating caused bad odor, thus many people around you dislike it and they might move away from you. Sweating especially on hands makes it difficult to grab things and this might bring suffer also.
