What Causes Excessive Sweating (Night Sweats or Spontaneous Sweating) in Men?
“Deficient sweating” is a term used in Traditional Chinese Medicine (TCM) to describe excessive, spontaneous sweating resulting from underlying imbalances or dysfunctions within the body.

What Causes Deficient Sweating in Men?
1. Yang Deficiency
Yang deficiency manifests with symptoms such as spontaneous sweating (deficient sweating), aversion to cold, pallor, and generalized fatigue. It commonly arises from severe depletion of kidney qi, irregular eating habits, or frequent overeating. Individuals exhibiting these symptoms should correct unhealthy dietary patterns and lifestyle routines. Incorporating kidney-tonifying foods—such as deer antler velvet—into the daily diet is also recommended.
2. Yin Deficiency
Yin deficiency occurs when the body’s yin fluids are insufficient to counterbalance yang, leading to a range of pathological changes. Typical manifestations include low-grade fever, dry mouth and throat, night sweats, insomnia, and a red tongue with scanty coating. Patients with yin deficiency may benefit from consuming yin-nourishing foods and herbs—such as tremella fungus and dendrobium—and combining them with TCM-based therapies for optimal results.

3. Diet
Poor dietary habits—particularly habitual consumption of high-calorie, spicy, or “heat-inducing” foods—can lead to internal heat accumulation, impaired spleen-stomach function, and chronic internal heat. Over time, this may trigger deficient sweating and adversely affect men’s health.
4. Underlying Diseases
Deficient sweating may also signal serious underlying conditions, including tuberculosis, lymphatic disorders, or endocrine diseases. These illnesses disrupt endocrine regulation, thereby increasing sweat production. Additionally, individuals with hyperthyroidism, diabetes, or those undergoing menopause are also prone to deficient sweating.
