What Causes Night Sweats in Men?

Normal sweating offers certain health benefits, such as aiding in the elimination of toxins from the body and promoting overall well-being. However, not all sweating is related to detoxification—for instance, night sweats (also known as “thief sweats”) are unrelated to toxin removal and instead often signal an underlying health issue. If left unaddressed, night sweats may lead to physical weakness, weight loss, and even secondary illnesses. So, what causes night sweats in men? Below, we address this question.

Causes of Night Sweats in Men

Generally, night sweats in men may stem from factors such as excessive stress, malnutrition, or kidney deficiency. A detailed analysis follows:

1. Excessive Stress

Many men develop suboptimal health due to prolonged exposure to heavy work- and life-related stress, resulting in symptoms such as chills and night sweats during sleep. In such cases, improving mental well-being and promptly relieving stress typically alleviates night sweats.

2. Malnutrition

Deficiencies in trace elements can also trigger nocturnal sweating. During sleep, men may experience electrolyte imbalances, leading to substantial loss of trace elements—potentially causing symptoms such as impaired memory and generalized weakness. In children, severe night sweats may delay intellectual development. In serious cases, patients may deteriorate clinically and even develop dehydration, posing significant risks to health. Under medical guidance, patients may be prescribed medications such as Bacillus subtilis and Lactobacillus probiotic granules or Clostridium butyricum probiotic powder for treatment.

3. Kidney Deficiency

Kidney deficiency—particularly kidney yin deficiency, though sometimes kidney yang deficiency—can cause night sweats in men. Therefore, accurate diagnosis of the specific type of kidney deficiency is essential to guide appropriate treatment. Timely consumption of foods that nourish the kidneys may help alleviate nocturnal sweating.

       In addition to the above common causes, tuberculosis can disrupt the endocrine system, thereby contributing to night sweats in men. Prompt medical evaluation is recommended to identify the underlying cause and initiate targeted therapy.

The above outlines the primary causes of night sweats in men. We hope this information proves helpful.
