What causes men to sweat at night during sleep?

Night sweats during sleep usually refer to nocturnal hyperhidrosis. In men, nocturnal sweating may be caused by factors such as high ambient temperature, psychological stress, hypocalcemia, late-onset hypogonadism, and diabetes. It is recommended to seek timely medical evaluation to identify the underlying cause and receive appropriate symptomatic treatment under the guidance of a qualified physician. The specific analysis is as follows:

1. High Ambient Temperature

The human body maintains a constant body temperature by sweating to dissipate heat when the surrounding temperature rises. During nighttime sleep, the body is in a relaxed state and becomes more sensitive to changes in environmental temperature, which may lead to nocturnal sweating. Usually, no specific treatment is required. Adjusting indoor temperature to create a comfortable sleeping environment, using breathable bedding materials, and reducing the thickness of blankets are recommended.

2. Psychological Stress

Psychological stress can activate the autonomic nervous system, increasing sweat gland activity. Especially during deep sleep, the body's response to psychological stimuli becomes more pronounced, leading to night sweats. Generally, no special treatment is needed. Practicing relaxation techniques such as deep breathing, yoga, or meditation can help alleviate psychological stress.

3. Hypocalcemia

Hypocalcemia may result from conditions such as hypoparathyroidism or certain medications. Low serum calcium levels can cause neurological disturbances, leading to sympathetic nervous system overactivity and increased sweat secretion. Symptoms may also include hand and foot spasms, leg cramps, and facial muscle twitching. Treatment may include calcium supplements such as calcium carbonate D3 tablets, calcium citrate tablets, or calcium gluconate oral solution, as directed by a physician.

4. Late-Onset Hypogonadism

Late-onset hypogonadism may be triggered by poor lifestyle habits, psychological factors, and others. Decreased testosterone levels can disrupt the body's thermoregulatory center, resulting in impaired temperature regulation. Nocturnal sweating is one of the common symptoms, often accompanied by fatigue, reduced libido, and decreased muscle strength. Medications such as finasteride tablets, spironolactone tablets, or compound xuanju capsules may be prescribed under medical supervision.

5. Diabetes

Diabetes may be caused by factors such as improper diet and genetic predisposition. In a state of high blood glucose, abnormal metabolic processes may trigger responses in the autonomic nervous system, leading to night sweats. Other symptoms may include excessive thirst, frequent urination, and fatigue. Medications such as metformin hydrochloride tablets, glimepiride tablets, or acarbose tablets may be used as prescribed by a doctor.

In daily life, it is advisable to avoid spicy, greasy, and other irritating foods to prevent worsening of symptoms. Additionally, engaging in moderate physical exercise can improve physical fitness and boost immune function, which may help alleviate night sweats.
