Introduction
In general, persistent sweating of the palms may be caused by factors such as emotional stress, high ambient temperature, hyperhidrosis, hyperthyroidism, or diabetes. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate symptomatic treatment under a doctor's guidance. In daily life, maintain clean and dry palms, avoid frequent contact with irritants, and choose breathable gloves, socks, and footwear.
Under normal circumstances, persistent sweating of the palms may be caused by psychological and emotional factors, high ambient temperature, hyperhidrosis, hyperthyroidism, diabetes, and other conditions. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under a doctor's guidance. Specific analysis is as follows:
1. Psychological and emotional factors: Prolonged tension, anxiety, or excessive stress can stimulate sympathetic nervous system activity, increasing sweat gland secretion and leading to sweaty palms. Maintaining a calm mindset, regulating emotions through meditation, deep breathing, and similar techniques, avoiding excessive anxiety, and seeking psychological counseling when necessary can help manage this condition.
2. High environmental temperature: In hot environments or when wearing excessively thick clothing, the body regulates its temperature through perspiration. As the palms are rich in sweat glands, they are particularly prone to increased sweating. Lowering the ambient temperature appropriately, choosing breathable and moisture-wicking clothing, and reducing heat and humidity exposure can alleviate this issue.
3. Hyperhidrosis: Caused by sympathetic nervous system dysfunction or genetic factors, this condition is characterized by abnormally excessive sweat gland secretion, resulting in frequent and profuse sweating of the palms. Topical treatments such as aluminum chloride solution, methenamine solution, or formaldehyde solution may be used as directed by a physician.
4. Hyperthyroidism: Excessive secretion of thyroid hormones accelerates metabolism, increases heat production, and stimulates sweat glands, leading to symptoms such as sweaty palms, palpitations, and hand tremors. Medications such as methimazole tablets, propylthiouracil tablets, or carbimazole tablets may be prescribed to inhibit thyroid hormone synthesis and relieve symptoms.
5. Diabetes: Poor blood glucose control can damage nerves and blood vessels, impairing sweat gland regulation and causing sweaty palms. This may also be accompanied by fatigue, increased thirst, and frequent urination. Strict blood glucose control is essential, and medications such as metformin hydrochloride tablets, gliclazide modified-release tablets, or insulin injection may be used as prescribed.
In daily life, maintain clean and dry palms, avoid frequent contact with irritants, choose breathable gloves and socks, minimize discomfort from sweat accumulation, maintain regular作息 (daily routines), and avoid staying up late to reduce physical strain.
