Spring, from the day of beginning of spring to the day of long summer, includes six solar terms: beginning of spring, Rain, Sting, Equinox, Qingming and Grain Rain. Traditional Chinese medicine believes that the following four principles should be paid attention to in spring health preservation: nourishing yang qi "Nourishing yang in spring and summer" is clearly pointed out in Huangdi Neijing. It means that in spring and summer, people should pay attention to maintaining the yang in their bodies. What is Yang? That is what people usually call "firepower", that is, the metabolic capacity of the human body. If the firepower is insufficient, there will be symptoms such as chills and cold limbs. There are many ways to maintain the human body's yang, and the most important one is "cover", that is, as the saying goes, "cover in spring and freeze in autumn". Why build it? This is because the climate in spring is often warm and cold, so don't cut clothes, just as Qin Shou pointed out in his new book for the aged, "The weather is getting warmer in spring, and clothes should be cut gradually so as not to make people catch cold." It also emphasizes that people who are weak should pay attention to keeping their backs warm. To maintain yang, you need to eat more leeks. Leek, although evergreen all year round, is eaten all year round, but it is best to eat more in spring. As the saying goes, "Chinese chives smell sweet in spring and stink in summer." Chinese medicine believes that leeks are warm and often eaten in spring, which is most helpful for nourishing yang. Traditional Chinese medicine believes that the liver governs spring, which means that the liver, one of the five internal organs of the human body, corresponds to spring. Why is there such a statement? Because the warm climate in spring will increase people's activity and promote metabolism. Therefore, in the human body, both blood circulation and nutrient supply will be accelerated and increased accordingly to meet the needs of various life activities. Chinese medicine believes that these are related to the physiological function of the liver. If the liver function is abnormal and can't adapt to the climate change in spring, a series of diseases will appear in the future, especially those with mental illness and liver disease, which are easy to get sick in spring and summer. As the saying goes, "cauliflower is yellow, idiot is busy." According to statistics, the incidence of mental illness is the highest in March and April, which is also a response to the influence of seasons on the body. This is the reason why Chinese medicine says "nourishing the liver in spring". There are many ways to maintain the liver, such as not being too tired in spring, so as not to increase the burden on the liver. Patients with liver disease and hypertension should take medicine in time according to the doctor's advice when spring comes. Especially for mental patients, attention should be paid to avoiding mental stimulation in spring to avoid aggravating the condition. Windproof temperature The reason why windproof temperature is emphasized in spring is because it turns from cold to warm at this time, and the temperature poison begins to stir. If you are weak at ordinary times, you will suffer from wind and fever (such as influenza) due to exogenous pathogens. According to folk experience, the following methods can be used to prevent it: First, soak it in water. Take 500g of Rhizoma Osmundae, put it into a water tank or bucket, and change it every month 1 time. Secondly, put some peppermint oil in the house and let it evaporate slowly to purify the air. Practice has proved that this method has a certain bactericidal effect. In addition, for the elderly and infirm, we should also try to avoid going to public places with many people and turbid air. At the same time, we should also pay attention to the freshness and circulation of indoor air. China health practitioners who are diligent in exercise also believe that in sunny spring days, it is appropriate to climb mountains, enjoy flowers, take a walk and swim in the mountains. However, it should be noted that exercise should be moderate, and it is necessary to feel energetic and relaxed after exercise. Huangdi Neijing also pointed out: "Lie down at night and get up early, stride forward and slow down your mission." It means that people should stay up late and get up early in spring, let loose their hair, stretch their bodies and walk in the courtyard, which can make wisdom and inspiration endless. These are all valuable experiences of ancient people in keeping in good health in spring, which are worthy of serious implementation by modern people.
