Night sweating in men during sleep is a phenomenon of night sweating. From the point of view of Chinese medicine, it is generally considered as Qi deficiency, Yin deficiency or Liver fire. In Chinese medicine, sweating is the fluid of the heart. Sweating at night can occur when there is a deficiency of qi that does not hold the fluid, or when there is a deficiency of yin that disturbs the heart and forces the fluid out, or when there is dampness and heat in the liver meridian that forces the fluid. In the treatment of night sweats, Chinese medicine practitioners also choose to treat the symptoms according to these different pathological mechanisms. Western medicine theory is that night sweating belongs to the category of autonomic nerve dysfunction, generally through the regulation of sleep, can improve the phenomenon of night sweating.
