Sweating is a physiological fact, a sophisticated system refrigerant that counteracts the rise in body temperature.
Sweating is normal for the body, is a kind of refrigeration system, as it begins to sweat when the body temperature is likely to rise well above 37 ° C. It 'a defense mechanism, activated by' hypothalamus that when you realizes that the temperature is likely to rise excessively, gives the order to more than two million sweat glands begin their work. When you sweat, also, we get rid of toxins and metabolic waste, so sweating is also a way to purify the body and of itself, the sweat is odorless, begins to be smelly, and in any case different from subject to subject, when the bacteria present on the skin that feed on sweat and begin decomposing.
There is no fixed rule about the amount of sweat, so everything is very subjective. There is sweating more and some less, but there are people who sweat excessively, and in this case suffer from hyperhidrosis, a disorder rather than a disease, which can nevertheless have an effect on the social life of the person who suffers, because usually it tend to isolate themselves from others.
So, as mentioned above, you can not tell if you sweat too much or little face bad or good, it is simply a condition dictated by the body that seeks to maintain the temperature within safe limits.
Sweating are also lost water and minerals and many other substances which it is composed sweat and, to be precise, chlorides, carbonic acid, sulfates, ammonia, potassium, calcium, magnesium, urea, uric acid, glucose, lactic acid, acetone , amino acids and fatty acids. Of course, when you sweat excessively as for example, when it carries out some physical activity, it is necessary to hydrate in an appropriate manner, so as to restore at least in part what is lost with the sweat that, in normal conditions, is constituted by a quantity liquids varying from half to eight liters per day.
The sweating, however, is not only related to physical activity or to the fact of being exposed to an elevated temperature, for which it triggers the mechanism of refrigeration which was mentioned previously. Sweat can also be a sign of malaise body tied to a lack of protein, vitamin deficiencies, hyperthyroidism, cardiovascular disorders, metabolic disorders, obesity, diseases of the lymphatic system, lung disease, menopause, but also to issues of character emotional. In fact, it is common to sweat if you are very agitated, worried, like when you have to take an exam or a job interview is particularly important.
In fact, it is not uncommon to have sweaty hands, which over all uncomfortable, discomfort that increases even more sweating.
Lock the sweating, even if not permanently, can be a problem, since it fails the normal cooling effect, in addition to the purification of the organism, because in fact would not remove all the waste which is necessary to remove periodically.
This means that sweat is good, you should sweat at least once a day, and the best way to do this is the 'physical activity, rather than expose himself to such temperatures that would put in place perspiration.
So, eat more fruits and vegetables and dairy products and instead limit the consumption of meat sausages, spicy foods, alcohol and coffee.
Even the clothing is important since it is necessary not to block the passage of air, the ventilation, so less heads made of synthetic fabrics which are to be preferred those made from natural fibers such as cotton, wool, silk, all fibers that allow a normal parts air and that, in case of sweating, also favor a more efficient evaporation of sweat.
