Traditional Chinese medicine believes that the liver governs hair growth, so the liver qi is vigorous in spring, and the liver Mu Yi dotes on the spleen, so improper health preservation in spring is easy to damage the spleen and lead to the decline of spleen and stomach function. After the solar term of rain, with the increase of rainfall, the evil of cold and dampness is most likely to trap the spleen. At the same time, it is difficult to get rid of the lingering dampness, and the spleen should be maintained before and after the rain. The key point of invigorating the spleen in spring is to regulate the liver, keep the harmony and smoothness of liver qi, keep a balanced diet, and keep the corresponding proportion of protein, carbohydrate, fat, vitamins and minerals in food. At the same time, we should keep the balance of five flavors, try to eat less spicy food and eat more fresh vegetables. Secondly, we should pay attention to strengthening the spleen and promoting diuresis. The purpose of nourishing the spleen is to nourish the temper internally and clear the damp evil externally. Spring is chilly, and moisture generally comes from "cold", so be sure to keep warm before and after the rain, and don't catch cold. At the same time, eat less cold things to protect spleen and stomach yang. Usually you can eat more crucian carp, carrots, yam, millet and other foods to achieve the purpose of strengthening the spleen. We should also guard against "cold spring" in the rainy season. This is because the rain in early spring will cause a sudden drop in temperature, which is particularly threatening to the health of the elderly and children. Especially when the temperature drops suddenly, the blood pressure of the elderly will increase significantly, which is easy to induce heart disease and myocardial infarction. As the temperature changes, children are prone to respiratory diseases, leading to colds and fever. So remind everyone again that you should pay attention to keep warm in spring and don't cut your clothes too early.
