While sweating may be a very natural body function, it can also be a very embarrassing one for many people. In fact some people have a problem with excessive underarm sweating, which can end up being not only an embarrassment but also very difficult to overcome.
Sweating helps to regulate body temperature. Sweat, also known as perspiration, is normal. Some people sweat under their arms much more than others, and the liquid that is secreted not only contain water and salt, but also other substances and minerals that the body is trying to eliminate.
The proper term for extreme sweating is called hyperhidrosis. Many people question why they sweat more under their arms than in other parts of their body, or why they sweat more than other people seem to.
As with all bodily functions, the first place the process of sweating starts is with the brain. Your brain decides how much your body should sweat and where you should sweat, determining this by gauging how much your temperature needs to be regulated, and what toxins or other substances need to be eliminated from your body via your skin. It decides which of your sweat glands to use.
Some people find that they sweat more under their arms. Others may sweat on their forehead, under their nose, or they may have sweaty feet or sweaty palms. It is often different for differing people, not only the amount a person sweats but also which areas are the sweatiest.
When a person experiences excessive perspiration, it is mainly due to their Sympathetic Nervous System becoming over stimulated for some reason. There is no simple explanation for why it happens, or what causes it, and it seems to be caused by many different reasons. Of course, some things are known and are constants. It has been proven that people sweat less during the night. Of course, most people sweat more while exercising. People who smoke cigarettes or drink too many caffeinated drinks also tend to have problems with sweating, as can people who regularly put a lot of salt o their food.
As far as controlling sweating, some things that may help are having a healthy diet, trying to be as stress free as possible and keeping your mind and body relaxed and peaceful.
