To the seventh sweatSweat is only water solution of salts and the organic substances, allocated by specialised glands. It contains 98-99 % of water and all "additives": nitrogenous substances (urea, uric acid, Creatinine, ammonia), some amino acids (серин, histidine), protein traces, urokaninovy acid, flying fat acids, soaps, cholesterol, salts of alkaline metals (sodium chloride), glucose, vitamins, biogene амины, catecholamines, histamine and steroid hormones. The content of mineral and organic substances in sweat changes depending on nature of a food and the general condition of an organism.

Smell. Sweat exhales not the most pleasant aroma for a human nose is all it is known. However it will be also interesting to much to learn that, actually, fresh sweat of a smell practically has no. Habitual aroma appears only when on skin bacteria start to breed. In other words, a stench - a product of merge of the liquid allocated from an organism and the microorganisms living on a surface of skin. Let's notice that though men sweat more, concentration of unpleasantly smelling, flying karbonovy acids in their case just the same, as well as at women, however sweat of a strong half of mankind contains more water. Not the secret that a smell of man's sweat differs from the female. It is connected with that on skin at young men and girls various microorganisms contain. It is important to know that together with then from an organism exchange products, the remains of medicines and even poisonous substances are removed. Repellent aroma of vydeleniye can be caused as well by these reasons. However many people specially visit baths, steam rooms and saunas that through a plentiful potootdeleniye to clear an organism of all above-mentioned.

Dislocation. Sweat is made from 2-4 million sweat glands of our organism which are settling down in the top layers of skin. The main concentration of glands is the share of zones of hands, armpits, feet and a groin. Funny, but most of all them contains at the person on palms - till 600 time on one square centimetre, and also on a forehead - till 300 time on square centimetre. A little smaller amount of glands is on soles, back surfaces of feet and brushes. As a rule, on sgibatelny surfaces of their extremities more than on the razgibatelny.

Gipergidroz. This word occurs from Latin "hyper" that means "raised", and "hydra" that corresponds to the concept "water". Proceeding from it, it is simple to guess that this illness doctors call the raised or superfluous potootdeleniye. This pathological condition, being characterised that the person intensively sweats even at small excitement, and even at all at thought, for example, about hands and handshakes. The described problem is a consequence of violation of normal work of sweat glands. At healthy people sweat glands allocate per day from 300 to 800 milliliters of sweat, and in a heat and at physical activity - to one and a half litres. By itself, at гипергидрозе these indicators increase. According to different data, a disease it is subject from 1 to 15 % of the population of a planet. Treatment is offered, generally surgical. After the operation which is carried out through a microscopic cut, doctors guarantee 90 % treatment.

Without sweat. In the wild nature of business are a little differently, rather than than at the person. Sweat of a hippopotamus, for example, contains red and orange pigments which absorb an ultraviolet and affect skin of the giant as sun-protection cream. At birds of sweat glands is not present and in mention therefore the feathery escape from a heat only by means of advanced respiratory system. To put out language and to open a mouth for cooling house cats and dogs at whom the minimum quantity of sweat glands settles down on small pillows of paws are compelled. Rabbits and pigs are incapable to sweat also. So the known joke about an internal monologue of a dog is apparently quite far from a real state of affairs: "When I worry, I - sweat … when I sweat - I stink … when I stink - me wash … when me wash - I worry..."
