Sweating is a very effective way to fight heat. In a dry environment at a temperature of 29 degrees C, people start sweating. Heavy workers in hot environments can secrete every hour to 2 liters of sweat, making wet clothes look like a bath.

If for some reason without perspiration (little gland, air with high humidity), body temperature will increase, sometimes causing serious accidents. In a dry environment, people can withstand temperatures of more than 40 degrees Celsius; but the air was too moist, it was difficult to sweat, only 32 degrees C could not stand it anymore.

Much sweating causes the body to lose water and mineral salts, causing a ' burning throat, ' stopping secretion of saliva, blood clots, and reduced blood oxygen levels. Need plenty of water, drink little by little.

Unusual sweat

Fragrant sweat : According to the general book, the noble woman has a natural aroma. King Tang Minh Hoang (China) has a precious non-Duong family, who are precious to sweat. Therefore, the king gave each brocade a weave according to special specifications, cutting it into pieces so that the beautician could absorb sweat, and the woman quickly picked up the stew to keep the fragrance.

No one knows how much of the anecdotes are true, because it is possible that the monarchs are too fond of beautiful people who see sweat as well. As for most people, if you don't bathe regularly, the bad smell will become very uncomfortable. Folk has called this secretion "sweat" because it is not fragrant.

Armpit : Men or women can have armpit odor, but in females the rate is higher. In armpit people, sweat has certain special ingredients, residues include too much mixture of ammonia or fatty acid. Under the decomposition effect of bacteria, the odor combination appears.

Smelly fishy fish : Rich choline foods (egg yolk, liver, sea fish - especially cartilage, beans .) when entering the colon will decompose into TMA - a compound that smells fishy. Thanks to an enzyme, TMA decomposes into an odorless substance. A few people lack this enzyme so the remaining TMA follows the bloodstream throughout the body and is released to make breathing, urine, sweat smell like fish. Some cases are hereditary.
