The weather is dry recently, and my hands are always sweating. What happened? Thank you.

Sweating is a physiological phenomenon of human beings. When people wear too many clothes, eat too spicy food or do strenuous exercise in hot weather, their bodies will sweat, which are normal phenomena. But under normal circumstances, sweating is a problem, especially on the hands, which is probably caused by palmar hyperhidrosis.

Palmar hyperhidrosis is a disease of hand sweat gland hyperhidrosis, mainly manifested as palmar hyperhidrosis, accompanied by axillary hyperhidrosis, foot hyperhidrosis and head and face hyperhidrosis. Hyperhidrosis is divided into primary hyperhidrosis and secondary hyperhidrosis. Primary palmar hyperhidrosis is caused by excessive sympathetic nerve, and most patients with palmar hyperhidrosis belong to this kind of palmar hyperhidrosis. Secondary palmar hyperhidrosis is an increase in sweating caused by physical diseases of a few people, such as hyperthyroidism, endocrine diseases, menopausal endocrine disorders and so on.
