In recent years, with the accelerated pace of life and the intensification of social competition, people's living and eating habits have also changed, so many people around them often feel tired, weak, sore muscles and joints, dizziness, palpitations, sleep disorders, loss of appetite, loose stool, sexual dysfunction and other symptoms, as well as depression, upset, anxiety, irritability, memory loss, inattention, slow response and so on, that is, now. Then why do these symptoms appear in modern society with excellent medical level and material conditions? As early as more than 2,000 years ago, Neijing gave us a more appropriate explanation: "Today, people take wine as their pulp, act rashly, enter the room drunk, try their best to exhaust their essence and dissipate their truth, don't know how to hold it full, are always absent-minded, do things quickly, go against their orders, and lead an impermanent life." I haven't studied Neijing for a long time, but the ancient ways of keeping in good health of Chinese medicine implied in the book always move me. Neijing said: "The ancient people, those who knew it, used the method of Yin and Yang, combined the number of techniques, had a moderate diet, and lived regularly, so they could be in harmony with God and live a hundred years old." A few words have profound meanings, so I'll try to explain them briefly here. "Law lies in Yin and Yang": The simple understanding of law is imitation, that is, mastering the laws of natural changes to adapt to the changes of natural climate and external environment, so that people can not only adapt to the changes of natural environment, but also gradually understand and master nature and actively transform the environment to make it more suitable for human survival. As the idea of preserving health and preventing diseases, this theory mainly recognizes the changing law of nature and follows this law, thus reducing the occurrence of diseases. Therefore, Neijing clearly put forward the viewpoint of "the correspondence between man and nature". This view mainly expounds the relationship between climate and health and longevity and the influence of climate on health and longevity. In the theory of Su Wen in Neijing, the method of keeping in good health, which conforms to the four seasons of Yin and Yang and adjusts the mind, is a concrete embodiment of the thought of Yin and Yang. The ups and downs of yin and yang in the four seasons are manifested in different natural scenes and climates, which make everything grow and collect. In nature, people must adapt to the four seasons to balance Yin and Yang. "Combination of skills and numbers": combination can be understood as harmony, skills are the method of education, and numbers have many meanings. "Combination of skills and numbers" refers to mastering the art of health preservation. There are many kinds of TCM regimen, such as guided massage, tooth-picking bath, Wuqinxi, Tai Ji Chuan and Qigong. Its main purpose is to keep fit and prolong life through exercise. Sun Simiao, a great medical scientist in the Tang Dynasty, once pointed out in Qian Jin Fang: "The way to cultivate one's self-cultivation often lies in diligence, not in labor. And the running water does not rot, and the household axis does not squat, so it also moves because of it. " "Moderate Diet" and "Time Wheel of Internal Classic Su Wen Zangqi Method" think that we have summarized some reasonable diets. For example, "five grains are the supplement, five fruits are the help, five animals are the benefit, and five dishes are the supplement." Smell it and take it to make up for poverty. "This recipe has staple food and non-staple food, and expounds their respective functions. Cereals: rice, wheat, potatoes, millet, sorghum, etc. are staple foods, which are rich in carbohydrates and provide necessary heat and energy for the human body; Five fruits and five vegetables are non-staple foods, which provide a variety of vitamins, cellulose and trace elements for the human body and are essential in metabolism; Five livestock: pigs, cows, sheep, chickens and ducks provide essential protein, fat and various amino acids for human body. Therefore, "harmony of five flavors" is an important aspect of diet. In addition, "self-doubling of diet and stomachache" means that overeating harms the gastrointestinal function of human body and affects digestion. According to Tian's theory in Neijing, "Yin is born in five flavors and Yin is injured in five flavors". People rely on the five flavors of diet to nourish spiritual vitality and maintain normal life activities. If the five flavors are not harmonious, it will hurt the five internal organs. Therefore, "harmony of five flavors" can promote blood circulation, strengthen bones and muscles, make five internal organs peaceful, and live a long and healthy life. " "Regular life" means regular work and rest, and "regular life" means regular life for us. According to the change of seasons, the four-time theory in Neijing has formulated the corresponding work and rest system: in spring, "staying late and getting up early, striding to court", in summer, "staying late and getting up early, never tired of a hundred days", in autumn, "staying early and getting up early, enjoying the cock crow" and in winter, "staying early and getting up late, waiting for the sun". If we have a regular daily life, it will help our health and reduce the occurrence of diseases, otherwise we will be semi-old and senile. "Don't forget work" is work, including labor, labor and housing labor. There are three meanings: first, the combination of work and rest, moderate work and rest; Secondly, we should warn people not to be unconventional and pay attention to moral health. The third is to control "sexual intercourse" and not to discharge kidney essence. And those who "run amok, get drunk, try to exhaust their essence and dissipate their truth" are the important reasons for premature aging. Pay attention to the above aspects, and you can become a person with high moral cultivation, full spirit and abundant physical strength. If you don't pay attention to moral cultivation, violate routine work, don't have sex, and don't pay attention to protecting kidney essence, it will inevitably cause weakness and accelerate aging. What is implied in Neijing is not only the method of keeping in good health, but also a deeper understanding is the avenue of dealing with people and the sublimation of spirit.
