Exogenous wind-heat: wind-heat evil attack on the surface is easy to damage yang qi, leading to the surface of the coupling (pores) open and close the Department, thus causing the leakage of fluids. In addition, the wind-heat evil is easy to enter into the heat, resulting in the internal heat of the internal organs, which steam forced fluid leakage, resulting in sweating. 2. Lung qi deficiency: Chinese medicine believes that the lungs are the main body of the gas, lung qi deficiency is not solid, which leads to the leakage of body fluids. This is often accompanied by coughing and shortness of breath, fatigue (mental exhaustion, physical weakness), weak pulse and other manifestations. It is recommended that patients with colds and sweating go to a regular hospital and be treated under the guidance of a professional physician.
