“Immortality” is an unattainable dream and pursuit, and this dream is almost as old as the history of human civilization. There is nothing more precious than life, and it belongs to us only once. In order to realize the beautiful ideal of prolonging life and anti-aging, we must know how to maintain health. Our traditional culture believes that human life is “born from the qi of heaven and earth, and the law of the four seasons”, and that yin and yang are the source of life, and essence is the core of life. The foundation of life lies in essence, qi and spirit. Life is related to the five organs and meridians, and there are differences in human physique and reasons for the differences. TCM also classifies human physique scientifically and also points out the characteristics of human physique at different ages. The idea of health maintenance is rooted in the soil of traditional Chinese culture and is based on ancient Chinese philosophy and the basic theories of Chinese medicine, which is one of the essences of China’s profound traditional culture. The Chinese people’s knowledge of the traditional way of health care comes more from traditional Chinese culture, of course, health care can not be done deliberately, but in accordance with nature, the law of nature. The highest level of health care is to be in harmony with nature, to move to nourish the body, to quietly nourish the mind, and to sleep to nourish the soul. The natural way to nourish the natural body, dial their own biological clock, to prevent the invasion of toxins, to promote the elimination of toxins. In other words, the integration of nourishment into daily life, that is, the principle of nourishment in accordance with life, according to the rules of nature to govern our lives, to achieve the balance of the unity of heaven and man. When we talk about the unity of heaven and man, we mean that man lives between heaven and earth, in the six hemispheres (i.e., the “southeast, northwest and heaven”) and within the natural environment, and is part of the whole material world, that is, man and the natural environment are a whole. Laozi, the founder of Taoism, said in the Tao Te Ching: “Man follows the ways of the earth, the earth follows the ways of the sky, the sky follows the ways of the Tao, and the Tao follows the ways of nature”. The Taoist philosophy of health is based on “nature” as its core, and “nature” means that it is so, so natural. This passage means that people must follow the laws of the earth in order to survive, the land depends on the changes in the weather in order to produce everything, the weather is according to its Tao, that is, the laws and operation, and the Tao is those self-existing of course, that is, the so-called natural things. Another example is the Tao Te Ching (37 chapters), which says: “The Tao is always inaction and inaction”, “inaction” means following its nature without artificiality, no consciousness, no purpose, a completely natural process. This is the principle of Laozi’s understanding of the changes in the universe, and used in human health. It advocates that people should follow the natural way and adapt to the natural method, which is the concept of health care in accordance with nature. Confucius, the founder of Confucianism, advocated that “those who know are happy and those who are benevolent live long”, and put forward the famous “three precepts of a gentleman” theory of health care, which emphasizes the physiological stage of health care according to the time, that is, “when you are young, your blood is not yet settled, so you should abstain from sex; When he is strong, his blood is fresh, he should refrain from fighting; when he is old, his blood is declining, he should refrain from gaining”. This means that when a gentleman is young, his blood is not yet stable, so he should be wary of lusting after women; when he is strong, his blood is vigorous, so he should be wary of fighting; and when he is old, his blood is declining, so he should be wary of gaining. The “three precepts” proposed by Confucius accurately captured the weaknesses of human nature at different ages, reminding people to be vigilant and vigilant in order to improve their health, which pioneered the theory of health care at different stages. At the same time, it is also clearly pointed out that people should follow the physiological characteristics of the body at different times to stratify their health, which is also a kind of natural health refraction in accordance with the internal environment of the human body. The prosperous heyday of Chinese health culture has produced numerous works on health, the most notable of which is the “Yellow Emperor’s Classic of Internal Medicine”. For example, “Su Wen – Shang Gu Tian Zhen Lun” mentions the principle of health maintenance, which is “to follow the law of yin and yang, to be in harmony with the arts and figures, to eat and drink with moderation, to rise and live with regularity, and not to make delusions of labor, so that the form and the spirit can be in harmony with each other, and the end of its natural life, and to be a hundred years old before leaving”. Another example is “Suwen – four qi tune Shen Lun”: “The four times of yin and Yang, the fundamental of all things. So the sage spring and summer to nourish Yang, autumn and winter to nourish Yin, from its roots, so with all things floating in the door of growth. Against its roots, it is felled its original, bad its true carry on ……” four times yin and yang is spring, summer, autumn and winter of the four shifts, is the process of change of yin and yang wax and wane. And the change of the four seasons of yin and yang is to promote the process of “birth, growth, transformation, collection, hiding” of everything, everything in the world can not violate this natural objective law. The Suwen – four qi tune Shen Lun” also said: “Spring March, this is called hair Chen, heaven and earth are born, all things to glory, night sleep and get up early, wide walk in the court, was hair slow shape, in order to make Zhi Sheng …… summer March, this is called the show, heaven and earth, the gas interchange, all things are flashy, night sleep and get up early, not tired of the day …… autumn March, this is called Rong Ping, the weather to be urgent, the earth to be bright, early to sleep and get up early, with the chicken, so that the will be peaceful, in order to slow down the autumn punishment …… winter March, this is called closed and hidden, water ice ground chap, without disturbing the Yang, early to sleep and get up at night, must wait for daylight, so that the will if the ambush if hidden, if there is a private intention This is a discussion of the four seasons of health based on the Yellow Emperor’s Classic of Internal Medicine, which recognizes that the internal environment and the external environment of the human body correspond to each other. How to maintain harmony with nature, how to adjust the small universe of the human body to adapt to the big universe, those seemingly simple truths, but contains a profound philosophy, has a very profound scientific and technological implications. Have the Chinese people ever thought about why the zi hour is matched with the rat, why the ugly hour is matched with the ox, why the zi hour is matched with the gall bladder, and why the daw hour is matched with the large intestine? How similar is the modern time healing science with the time medicine of Chinese medicine. The functions of the human body actually change together with nature. Modern science has found that more than 60 chemical elements in human blood actually have obvious correlation with chemical elements in the earth’s crust. Amazingly, the distribution pattern of the elements in the earth’s crust and the elemental content in human blood are in perfect agreement. Man is closely related to nature, and man depends on nature to survive. Everything should be in accordance with the biological clock, which is the basis of biological clock health. Simply put, we should adapt to the daily rhythm, monthly rhythm and annual rhythm of the general environment, so that the daily diet, excretion, movement, sitting and lying are in tune and harmony with the rhythm. That is to say, “the future should not be welcomed first, do not worry too much about things, do not stay, listen to its own coming, should be natural, let it go”. Letting nature take its course is the purpose of anti-aging and anti-aging, but the disease to prolong life. If you go against your own habits and force yourself to follow the extreme precepts of health, you will only get the opposite result. Of course, we also oppose those who indulge in capricious “according to nature”, indulgence and deficiency can not achieve balance. It can be said that health is both easy and difficult, said it is easy means that health should not be a high condition or even physical problems to do things, but a daily attitude to life, generally after the age of 25 years old body organs tend to mature in the opposite direction, then health is definitely not the secret of the elderly longevity, but should become a mandatory course for young people to take care of the body; said it is difficult means that in order to really health In the current era, this simple thing has become the most desirable but unattainable thing. After birth and until old age. In the natural world, society, the seven emotions naturally arise best what sour, sweet, bitter, spicy taste should be tasted, happy, angry, bad, happy, sad, fear, frightened emotions should be had, but not too much. The more and deeper this experience, the stronger your adaptability, compensatory power, tolerance and resistance to disease. It is the same as having been born with Tianto measles and typhoid to gain lifelong immunity, so as to become a physically and mentally healthy person, a truly complete person. People can not live forever, but we can gradually enhance the physical fitness, improve the recovery power, resistance to decay, so as to achieve the purpose of prolonging life and improving the quality of life. This is of great benefit to individuals, as well as to the country and the nation. If people can take good care of their health, they can reach the age of “heaven”, otherwise they will “age” quickly and fail to achieve the purpose of “longevity”.
