Weakness of spleen and stomach will lead to dampness, and dampness will also lead to weakness of spleen and stomach, which is mutually causal. Traditional Chinese medicine says that spleen governs transport and transformation. When spleen deficiency water can't be metabolized, it will stay in the body and form moisture. Too much moisture will form phlegm-dampness, and it will be combined with other pathogens to form other diseases, such as cold-dampness combined with cold-pathogen, damp-heat combined with heat-toxin and so on. Since there is moisture in the body, it should be removed as soon as possible. There are five main reasons for moisture formation, 1. Spleen and stomach weakness. At present, most people are weak in spleen and stomach, so they can't digest something when they eat, and drinking cold drinks and eating cold food often hurts the spleen and stomach the most. 2. Emotional reasons, bad mood, depression, argumentative, easy to control, easy to hurt the liver if you think too much. Chinese medicine believes that the liver can spoil the spleen, and a bad liver will also hurt the spleen and stomach. 3. Environmental factors, stay away from damp and cold places, and choose a ventilated and sunny place to live. 4. Dietary problems, fat, sweet and thick taste hurt the spleen the most. 5. Qi and blood are weak, and qi is handsome as blood. Only when the qi and blood are vigorous and the meridians are unobstructed can moisture stay in the body. Therefore, strengthening the spleen and stomach and maintaining a good mood are the key to eliminating dampness.
