Introduction

Palmar hyperhidrosis (excessive sweating of the palms) may be caused by constitutional differences, high environmental temperature, hypoglycemia, hyperthyroidism, pneumonia, or other factors. In daily life, it is important to maintain good lifestyle habits, follow a balanced diet, avoid excessive fatigue and unhealthy habits, in order to preserve overall health and reduce the likelihood of abnormal sweating of the palms.

Generally, frequent sweating of the palms may be caused by constitutional differences, high environmental temperature, hypoglycemia, pneumonia, hyperthyroidism, and other factors. If the aforementioned conditions occur, it is recommended to seek medical treatment promptly. Detailed analysis is as follows:

1. Constitutional Differences

Each individual has a different constitution, and there are variations in the distribution and secretory function of sweat glands. Some people may naturally have more developed sweat glands in their palms, making them prone to sweating. This can be improved in daily life by adjusting lifestyle habits, such as wearing breathable clothing and keeping the hands dry.

2. High Environmental Temperature

When the environmental temperature is excessively high, body temperature rises, and the body sweats to dissipate heat and maintain normal body temperature. As one of the body's heat-dissipating areas, the palms may exhibit increased sweating. Air conditioners or fans can be used to regulate the temperature.

3. Hypoglycemia

Poor eating habits, excessive fatigue, heavy alcohol consumption, and other factors can trigger hypoglycemia. When blood sugar levels are too low, the body releases hormones such as adrenaline to maintain normal physiological functions, which can cause the aforementioned symptoms. Symptoms may include palpitations and hand tremors. Treatment may involve medications such as furosemide tablets, carbamazepine tablets, and phenobarbital tablets, under a doctor's guidance.

4. Pneumonia

There are numerous causes of pneumonia, including long-term heavy smoking and pathogenic bacterial infections. Inflammation in the lungs triggers an immune response, releasing inflammatory mediators that affect the hypothalamic thermoregulatory center, resulting in frequent sweating of the palms. Symptoms may include coughing and chest pain. Patients should follow medical advice and use medications such as penicillin V potassium tablets, doxycycline hydrochloride tablets, and fluconazole sodium chloride injection for treatment.

5. Hyperthyroidism

Hyperthyroidism is primarily caused by excessive secretion of thyroid hormones. When too much thyroid hormone is secreted, metabolism accelerates, increasing heat production, which can lead to frequent sweating in areas such as the palms. Symptoms may include palpitations and exophthalmos (bulging eyes). Treatment may involve medications such as methimazole tablets, propylthiouracil tablets, and levothyroxine sodium tablets, following a doctor's instructions.

Maintaining healthy lifestyle habits, eating a balanced diet, and avoiding excessive fatigue and unhealthy habits can help maintain overall health and reduce the likelihood of abnormal palm sweating.

Is sweaty palms due to yin deficiency or yang deficiency?

Both yin deficiency and yang deficiency can cause palmar hyperhidrosis (excessive hand sweating). Qi deficiency and psychological factors may also contribute to this condition. In cases of qi deficiency, the body’s vital qi fails to anchor and secure the essence and fluids, leading to leakage of body fluids and subsequent sweating. Yin deficiency generates internal heat; this heat forces out body fluids, resulting in symptoms such as heat sensation in the palms, soles, and chest (“five-center heat”), tidal fever, and sweating. Yang deficiency impairs the ability of defensive qi (wei qi) to remain anchored internally; consequently, defensive yang floats outward, causing spontaneous sweating. It is advisable to consult a qualified traditional Chinese medicine (TCM) practitioner locally for pattern differentiation and diagnosis.
