As spring returns to the earth and everything comes to life, the yang energy of the human body also tends to be on the surface and the liver energy rises. The human body responds to the four seasons, spring health care to nourish the liver to protect the liver as the first priority. If the liver wood is too strong, it is easy to grasp the spleen earth, which is not good for health. Sour taste into the liver, sweet taste into the spleen, “regimen news theory” pointed out: “when the spring, food taste should be reduced acid to increase the sweet, in order to nourish the spleen.” In spring, you can eat more red dates, yams and other sweet and warm foods that strengthen the spleen. Yang Qi rises, and old diseases are most likely to recur. For example, pollen in the air increases in spring, and bronchial asthma and other allergic diseases are easily triggered. As the saying goes, “when the cauliflower is yellow, the idiot is busy”, spring is also the peak period for the onset of mental illness, so people with mental abnormalities should pay attention to prevention and timely medical consultation. Hypertension, cerebrovascular disease and other diseases caused by hyperactivity of the liver are also at high risk in the spring, and the liver is prone to emotional instability due to the loss of the liver in the spring, so it is important to abstain from anger in the spring, to be open-minded and maintain a happy mood. In addition, in early spring there are often sudden changes in the weather, “warm at first but still cold”, “the most difficult to be rested”; spring because of disease-causing microorganisms with the temperature turned ambiguous and growth and reproduction, is the flu season, and therefore should not take off winter clothes too early to prevent colds, the ancient cloud “spring cover autumn freeze” is the way to maintain health. Spring is ambiguous, the human skin blood vessels and pores expand, the body surface blood circulation is strong, the brain blood supply is relatively reduced to reduce the excitability of brain nerve cells, easy to appear sleepy, people have the feeling of drowsiness. A reasonable diet, pay attention to the supplementation of B vitamins; warm weather and appropriate increase in outdoor sports, strengthen exercise, can effectively stimulate the function of the body systems, improve the “spring sleepiness”, improve the ability to resist disease.
