Sweating is a physiological mechanism that protects the body against overheating. Intensity of perspiration depends, among others, on the amount of sweat glands in the skin and individual sensitivity to emotional factors, weather conditions or diet.
When the amount of sweat is greater than what is required to maintain the body’s normal temperature – we are talking about hyperhidrosis. Excessive sweating is a problem affecting both women and men. It may accompany some diseases, such as infections with fever, overactive thyroid gland, diabetes, nervous system disorders or some types of cancers (so-called night sweats). Excessive sweating may also accompany menopause and andropause. This is called secondary hyperhidrosis. In turn, primordial hyperhidrosis (hyperhidrosis idiopathic) is an excessive sweating. Hyperhidrosis may occur on the whole body or be locally limited – in the second case it is usually face hyperhidrosis, hands and feet hyperhidrosis or armpits hyperhidrosis. What factors trigger excessive sweating? Causes are stress, strong emotions, high ambient temperature, physical effort or intake of spicy foods.
Excessive perspiration can cause discomfort and feelings of embarrassment, arousal, and may cause health problems (skin infections).
