Why do my hands sweat? There is something wrong with this nerve!

When in a high temperature environment, people will sweat to remove the body heat. The main places where people sweat are the forehead, armpits, etc. However, some people sweat a lot on their palms when they are not doing anything and are not in a very hot environment. What is the reason for sweaty hands?

Excessive sweating of hands is hyperhidrosis of hands and feet

If your hands and feet sweat too much, it is a kind of functional local abnormal hyperhidrosis of unknown cause. Excessive sweating of the hands and feet is also called "hand and foot hyperhidrosis" or "hand and foot hyperhidrosis". The secretion of sweat glands is controlled by the sympathetic nerves, and hand hyperhidrosis is caused by excessive tension of the sympathetic nerves for unknown reasons, such as tension, excitement, stress or high temperatures in summer, which causes abnormal increase in sweating of the palms. It can also be due to damage or abnormal reaction of the sympathetic nerves, increased secretion of acetic acid and bile alkaloids, resulting in excessive sweat secretion of small sweat glands.

The pathogenesis is still unclear

At present, the pathogenesis of hyperhidrosis of hands and feet is not clear. Most of them are caused by excessive hyperactivity of the sympathetic nerves that control sweating of hands. Traditional Chinese medicine believes that excessive sweating of hands and feet is caused by dysfunction of spleen and stomach.

Hyperhidrosis is always sweating for no apparent reason

Hyperhidrosis patients always sweat a lot, and their palms, soles and armpits are cold and wet, whether it is hot in summer or freezing cold. Sometimes they sweat in beads, and it is more serious when they are nervous. They often get the paper wet when writing, the keyboard wet when typing, and dare not shake hands with others. Patients with hyperhidrosis of hands and feet may sweat profusely and their palms sweat inexplicably in crowded places, when giving reports in meetings, when meeting strangers, when meeting acquaintances and leaders, when they are nervous and excited, when meeting the opposite sex, when discussing sensitive topics, etc.
