Why do my palms sweat without feeling hot?

Generally, non-heat-induced palmar hyperhidrosis is mainly caused by emotional tension, hormonal fluctuations, spleen and stomach weakness, autonomic nervous system dysfunction, and hyperthyroidism. If you experience any discomfort, please seek medical attention promptly. Detailed explanations are as follows:

1. Emotional Tension

Emotional fluctuations, especially states of tension, anxiety, or excitement, can activate the sympathetic nervous system within the autonomic nervous system, leading to increased sweating of the palms. Relaxation techniques such as deep breathing exercises, meditation, and yoga can help alleviate emotional tension and anxiety.

2. Hormonal Fluctuations

When hormonal levels fluctuate, the sensitivity of sweat glands may increase, resulting in palm sweating even in non-heat conditions. Maintaining a healthy lifestyle, such as regular exercise and a balanced diet, can help stabilize hormone levels.

3. Spleen and Stomach Weakness

Irregular eating habits and frequent consumption of spicy or cold foods can potentially damage the spleen and stomach. Spleen and stomach weakness can impair water metabolism and transportation functions, causing internal accumulation of dampness and fluid, which may be expelled through sweat. This may be accompanied by symptoms such as loss of appetite, abdominal distension, and loose stools. It is recommended to follow medical advice for treatment with medications such as Zhishi Da Zhi Wan, Domperidone tablets, and Jianwei Xiaoshi tablets.

4. Autonomic Nervous System Dysfunction

Autonomic nervous system dysfunction is related to nerve abnormalities. Dysfunction of the autonomic nervous system affects the normal regulatory function of sweat glands, leading to abnormal sweat secretion. It may be accompanied by various autonomic nervous system symptoms such as palpitations, chest tightness, and insomnia. Treatment should follow medical advice using medications such as Gultathione tablets, Vitamin B1 tablets, Midodrine Hydrochloride tablets, etc.

5. Hyperthyroidism

Factors such as family or genetic predisposition, being female, a history of autoimmune diseases, and intense psychological stress can trigger hyperthyroidism. Thyroid hormones promote metabolism and energy consumption, leading to increased body heat production and excessive sweat gland secretion. Symptoms may include irritability and increased appetite. Under the guidance of a professional physician, treatment can involve medications such as Methimazole tablets, Propylthiouracil tablets, and Levothyroxine Sodium tablets.

Reduce friction between the hands and hard objects and avoid tightly gripping items for prolonged periods to minimize hand sweating.
