What causes excessive sweating during sleep at night, resulting in being completely soaked?

Generally, excessive sweating during sleep at night that soaks the entire body may be caused by factors such as a hot and stuffy environment, improper diet before bedtime, hyperthyroidism, diabetes, or tuberculosis. If discomfort occurs, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. Specific analyses are as follows:

1. Hot and Stuffy Environment

High room temperature and poor ventilation during sleep can hinder the body's heat dissipation, leading to increased sweat gland secretion to regulate body temperature, resulting in whole-body sweating. Open windows for ventilation promptly, use air conditioning or fans to cool down, and choose breathable, sweat-absorbing sleepwear and bedding.

2. Improper Diet Before Bedtime

Consuming spicy foods or alcohol before sleep can irritate the gastrointestinal mucosa (from spices) and dilate blood vessels (from alcohol), accelerating blood circulation and stimulating sweat gland secretion. Avoid eating spicy or irritating foods before bed, reduce alcohol intake, and maintain a light diet.

3. Hyperthyroidism

Excessive secretion of thyroid hormones accelerates the body's metabolism, increases heat production, and leads to sweating for heat dissipation. Medications such as methimazole tablets, propylthiouracil tablets, or metoprolol tartrate tablets may be used under medical guidance. Maintain regular作息 and avoid fatigue.

4. Diabetes

Large fluctuations in blood glucose levels or nocturnal hypoglycemia can stimulate the sympathetic nervous system, causing sweating. Medications such as metformin hydrochloride tablets, glimepiride tablets, or insulin aspart injection may be used as directed by a physician. Monitor blood glucose regularly and maintain consistent meal times.

5. Tuberculosis

Infection with *Mycobacterium tuberculosis* triggers inflammation and stimulates the body to produce pyrogenic substances, leading to night sweats. Medications such as isoniazid tablets, rifampicin capsules, and ethambutol hydrochloride tablets may be prescribed. Ensure adequate rest and nutritional support during treatment.

In daily life, keep the bedroom well-ventilated and cool; maintain proper dietary habits before bedtime and avoid irritating foods; undergo regular health check-ups to monitor vital indicators; and strictly follow medical instructions for medication use without adjusting dosages arbitrarily.
