Sweating is a physiological fact, a sophisticated cooling system that counteracts the increase in body temperature.
Sweating is normal for the body, is a kind of cooling 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 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, in addition, you get rid of toxins and metabolic waste, so sweat is also a way to purify the body and of itself, the sweat is odorless, begins to be smelly, and however different from subject to subject, when bacteria 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 you sweat 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 may, however, have an impact on the social life of the person who suffers, because they usually tend to isolate themselves from others.
So, as mentioned earlier, 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 make up the sweat and, for the accuracy, 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 performing a certain 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, under 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 a high temperature, for which it triggers the mechanism of refrigeration which was mentioned previously. Sweat can also be a sign of sickness of the 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, uneasy 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 body, because in fact it 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 as it is necessary not to block the air passage, the ventilation, then less garments made of synthetic fabrics which are to be preferred those made of natural fibers such as cotton, wool, silk, all fibers that allow a normal parts air and that, in the case of sweating, also promote a more efficient evaporation of sweat.
