Perspiration is a natural process our bodies go through each day.Perfectly normal to sweat, and the amount of sweat that is eliminated through the body can vary in each person. However, there are people who suffer from excessive sweating of the armpits, and this is called axillary hyperhidrosis. Usually the people affected are literally drops of sweat from their armpits, and have a constant odor that is usually resistant to all deodorants.
If you are unlucky enough to suffer from this condition, it will often be prevented from wearing clothes by some as the sweat tends to show through some materials. Why suffer the condition of sweat a lot, because the glands have been stimulated by more than sympathetic nervous system. Thus, some tissues are wearing worse than others, for example, if a woman with this condition is wearing something that is silk, the sweat will leave very obvious wet rings under your arms, causing embarrassment and low self-esteem.
