Introduction
In general, excessive sweating may be caused by factors such as hot environments, emotional stress, hyperthyroidism, diabetes, or hyperhidrosis. If discomfort occurs, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. In daily life, choose breathable and loose-fitting clothing, maintain emotional stability, and avoid excessive tension.
Generally, excessive sweating may be caused by factors such as hot environments, emotional stress, hyperthyroidism, diabetes, or hyperhidrosis. If discomfort occurs, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. Specific analysis is as follows:
1. Hot environment: In high temperatures, the body's thermoregulatory center stimulates sweat glands to secrete sweat, which helps maintain stable body temperature through evaporative cooling. Move promptly to a cool, shaded area, reduce clothing coverage, and drink more cool boiled water to replenish fluids.
2. Emotional stress: Intense emotions stimulate sympathetic nervous system activation, increasing sweat gland secretion as part of the body’s stress response. Calm down through deep breathing, listening to soothing music, avoiding stressful situations, and maintaining emotional stability.
3. Hyperthyroidism: Excessive secretion of thyroid hormones accelerates metabolism and increases heat production, leading to overactive sweat glands. This condition is often accompanied by palpitations and hand tremors. Medications such as methimazole tablets, propylthiouracil tablets, and metoprolol tartrate tablets may be used as directed by a physician. Avoid consuming iodine-rich foods.
4. Diabetes: Blood glucose fluctuations or hypoglycemic episodes can activate the sympathetic nervous system, causing sweating, often accompanied by dizziness and palpitations. Medications such as metformin hydrochloride sustained-release tablets, glimepiride tablets, and insulin injection may be used under medical guidance. Regular blood glucose monitoring and dietary control are essential.
5. Hyperhidrosis: Dysregulation of the sympathetic nervous system leads to excessive sweat gland secretion, resulting in abnormally increased localized or generalized sweating. Treatments may include aluminum chloride solution, hexamethylenetetramine solution, or oryzanol tablets as prescribed. In severe cases, endoscopic thoracic sympathectomy may be required.
In daily life, choose breathable and loose-fitting clothing; maintain emotional stability and avoid excessive anxiety; follow a balanced diet and regular作息; seek medical attention promptly for abnormal sweating to identify the underlying cause and receive appropriate treatment.
