Once the physiological function of the spleen is weakened, the spleen’s function of transforming dampness will be reduced, so the diet has a great impact on the spleen. Emotionally, many people like to sulk, like to lose their temper, usually small things they can not think, long-term will lead to liver qi stagnation. When liver qi is stagnant, the entire qi flow is not smooth, which will also hinder the spleen’s transportation and spleen’s transportation of dampness, so it will aggravate the accumulation of dampness in the body, which will also form water dampness. There are some diseases, such as for some organic diseases, whether it is various internal organs, heart disease, kidney disease or liver disease, and digestive system diseases, will cause dampness heavy, so that dampness accumulates in the body. And the work environment, such as often work in wet places, especially cold places, such as in the south there are places without heating equipment, in the winter will be very cold, and in the summer will be very hot and humid, northerners may not adapt, this situation will affect the normal spleen and stomach on the transport of damp. Because of the normal long life in the local, has formed the internal organs and climate adaptation, a sudden shift to a place, northerners to the south, increased the burden on the spleen and stomach, the ability to transform dampness will decline, excess dampness will stay in the body volume. If it is in a cold and damp place, it may cause cold and damp paralysis, which can cause pain in the joints of the limbs.
