Night sweats refer to sweating when sleeping at night. After waking up, sweating will stop, but clothes and quilts are wet. For many people, night sweats mean weakness. From the perspective of traditional Chinese medicine, night sweats are caused by excessive moisture in the body, which leads to spleen deficiency or internal heat. Spleen deficiency cannot transport qi and blood, and qi cannot absorb body fluid. At night, the situation of yin deficiency and excessive fire is more serious. Deficiency and heat disturb body fluids, so sweating and night sweats occur.

Spleen deficiency can not transport water and dampness, and moisture is trapped in the spleen for a long time, which hinders the transport function and is very harmful to the body. "Spleen deficiency leads to dampness", which will aggravate spleen deficiency and form a vicious circle. Therefore, in order to completely eradicate night sweats, we must strengthen the spleen and eliminate dampness from the root.
