There are two different reasons behind the problem of excessive sweating in the hand area. The first is psychological sweating triggered by emotions such as embarrassment, excitement and stress. The second is sweating caused by some diseases and medications used.
The act of sweating is the body's way of cooling itself. When body temperature rises, the nervous system activates the sweat glands. Sweating in the palms is a common occurrence when we feel tense and under pressure. The most common type of hyperhidrosis is primary focal hyperhidrosis. In such cases, the nerves responsible for sending signals to the sweat glands are overactive. This situation becomes even worse in times of stress and tension. In these cases, the palms, face and soles of the feet are affected. Genetic factors are effective and there is usually no underlying medical reason. Secondary hyperhidrosis occurs. Such cases are rarer than others. In these cases, sweating occurs all over the body. It occurs in cases of thyroid problems, heart attack, diabetes, infections, menopause and cancer.
