What causes sweaty palms?
Generally, sweaty palms may be caused by high ambient temperature, improper diet, emotional stress, hyperthyroidism, or hyperhidrosis. If discomfort occurs, it is recommended to seek medical attention promptly. Detailed analysis is as follows:
1. High Ambient Temperature
When the environmental temperature rises, the body's thermoregulatory center signals the sweat glands to increase secretion in order to maintain thermal balance, resulting in sweaty palms. It is advisable to avoid prolonged exposure to high temperatures and to replenish fluids and electrolytes promptly.
2. Improper Diet
Consuming excessive spicy foods, alcohol, or other irritants may stimulate the sweat glands in the palms, leading to increased sweating. A light diet with reduced intake of irritating foods is recommended.
3. Emotional Stress
Emotional stress can activate the sympathetic nervous system, stimulating sweat gland activity and causing excessive sweating of the palms. Managing stress appropriately is important; if necessary, consultation with a psychologist or psychotherapy may be beneficial.
4. Hyperthyroidism
Hyperthyroidism may result from abnormal iodine intake. Excess thyroid hormone accelerates metabolism, leading to sweaty palms, possibly accompanied by symptoms such as palpitations, hand tremors, and irritability. Treatment under medical supervision may include medications such as methimazole tablets, propylthiouracil tablets, or propranolol hydrochloride tablets.
5. Hyperhidrosis
Hyperhidrosis may be related to genetic factors, anxiety, hypoglycemia, or other causes. It leads to overactive sweat glands and excessive sweating of the palms, often accompanied by symptoms such as peeling skin or infections. Treatment may include hydrogen peroxide solution, fluocinonide acetate cream, or phentolamine mesilate tablets, as directed by a physician.
In daily life, it is advisable to wear loose, breathable clothing and keep hands dry. In hot environments, take measures to stay cool, ensure indoor ventilation, and use air conditioning or fans as needed.
