What causes sweaty palms?

Under normal circumstances, sweaty palms may be caused by high environmental temperature, intense physical activity, hyperthyroidism, myocarditis, diabetes, or other reasons. Treatment can be carried out under a doctor's guidance through general management and medication. Specific analyses are as follows:

1. High Environmental Temperature

When the external temperature rises, the body maintains normal body temperature by secreting sweat through sweat glands to dissipate heat. The palms, being areas rich in sweat glands, are particularly prone to sweating. This can be relieved by using air conditioning or fans, or by moving to cooler environments.

2. Intense Physical Activity

During exercise, increased muscle activity generates substantial heat, and the body cools itself through sweating, which also leads to sweaty palms. After exercising, it is important to rest promptly and replenish fluids and electrolytes.

3. Hyperthyroidism

Hyperthyroidism is usually caused by thyroid nodules producing excessive hormones. Overproduction of thyroid hormones accelerates metabolism and increases body heat production, leading to increased sweating of the palms. Symptoms may include increased appetite with easy hunger, insomnia, and others. Treatment under medical supervision may include medications such as methimazole tablets, propylthiouracil tablets, and vitamin B complex tablets.

4. Myocarditis

Myocarditis is primarily caused by infections from viruses, bacteria, or fungi. It may damage myocardial cells, impair heart function, and indirectly increase sympathetic nervous system activity, resulting in excessive palm sweating. Symptoms may include chest pain and shortness of breath. Treatment should follow medical advice and may include medications such as coenzyme Q10 capsules, vitamin C tablets, and furosemide tablets.

5. Diabetes

Diabetes may result from genetic factors, unhealthy lifestyles, or viral infections. It can lead to autonomic neuropathy, causing abnormal sweat gland secretion and increased sweating of the palms. Symptoms may include weight loss, blurred vision, fatigue, and others. Patients should follow medical instructions to use medications such as metformin hydrochloride sustained-release tablets, acarbose tablets, and insulin injection solution.

In daily life, it is important to maintain a comfortable ambient temperature, engage in moderate exercise, rest and rehydrate promptly, monitor bodily changes, and maintain healthy habits to prevent abnormal sweating of the palms.
