What causes excessive sweating of the hands?

Generally, excessive sweating of the hands may be caused by factors such as ambient temperature, emotional stress and excitement, hyperhidrosis, endocrine disorders, or hyperthyroidism. If the above conditions occur, it is recommended to seek timely medical treatment. A detailed analysis is as follows:

1. Ambient Temperature

When the ambient temperature rises, the body secretes sweat through sweat glands to dissipate heat in order to maintain normal body temperature. As the hands are part of the body surface, they also tend to sweat more under these conditions. This can be improved by ensuring good ventilation and wearing breathable clothing.

2. Emotional Stress and Excitement

During emotional stress or excitement, increased sympathetic nervous system activity stimulates greater sweat gland secretion. Since the sweat glands in the hands are controlled by the sympathetic nerves, excessive sweating often occurs. In daily life, individuals should stay relaxed and may practice relaxation techniques such as deep breathing or meditation to help regulate this response.

3. Hyperhidrosis

Hyperhidrosis is a functional disorder characterized by abnormal localized sweating, possibly related to abnormal sympathetic nerve activity or influenced by genetic factors. This condition primarily manifests as excessive sweating on specific areas such as the palms and soles, and may be accompanied by symptoms like macerated or whitish skin on the hands. Patients should follow medical advice to take medications such as Ciwujia tablets, Vitamin B1 tablets, or Oryzanol tablets for treatment.

4. Endocrine Disorders

Endocrine imbalances are often associated with irregular sleep patterns, staying up late, and high stress levels. When hormonal levels become unbalanced, normal sweat gland function may be affected, leading to increased hand sweating. Other symptoms may include menstrual irregularities and decreased sexual function. Treatment under medical guidance may include medications such as Metformin Hydrochloride tablets,Progesterone capsules, or Levothyroxine Sodium tablets.

5. Hyperthyroidism

This condition can be triggered by genetic factors, excessive intake of iodine-rich foods, or infections. When excess thyroid hormones are secreted, the body's metabolic rate increases, resulting in overactive sweat glands and consequently excessive hand sweating. Symptoms may also include palpitations, irritability, and exophthalmos (protruding eyes). Treatment should follow medical advice and may involve medications such as Methimazole tablets, Propylthiouracil tablets, or Metoprolol Tartrate tablets.

Maintaining healthy lifestyle habits—such as regular sleep schedules, moderate stress reduction, good personal hygiene, and avoiding excessive tension or emotional excitement—can help maintain bodily balance and reduce episodes of excessive hand sweating.
