The term “health maintenance” was first used in Zhuangzi – The Inner Chapters, which refers to a kind of health care activity based on the law of life development and the adoption of means that can maintain the body, minimize diseases, improve health and prolong life. While learning the theory and method of health care, the following four principles of health care should be adhered to. First, establish a correct concept of life and death and health since the date of birth means the beginning of death, growth and old age is an irresistible objective law. How to deal with death, this is an unavoidable topic. Some people can be correctly treated, take it calmly; some people are fearful, terrified. The “anti-cancer clubs” and “diabetes clubs” organized by patients all over the country are a good demonstration of their love and hope for life. This is especially important for the elderly, the pursuit of health and desire for longevity is their greatest desire. Most of the elderly are weak and sickly, with various functions declining. They hope to have medical treatment and enjoyment in old age, and strive to find ways to prolong their lives, with a strong demand for medical care. Therefore, if they do not treat life and death correctly, they are likely to be deceived by some current profit-oriented health care providers and become the target of their interests. Second, the scientific treatment of traditional health preservation method The theory and method of health preservation is an important part of the traditional culture of the Chinese nation, but the traditional health preservation of good and bad, how to treat them correctly? The scientific method is to remove the false and select the best, which is a basic principle of inheriting traditional culture and acquiring knowledge of health care. In recent years, with the return to nature and the emergence of global health care fever, some people take advantage of the people’s pursuit of health of the good wishes, under the cloak of science, under the banner of promoting traditional culture, peddling around the feudal dregs of long been thrown into the garbage heap of history and superstition and witchcraft, often with the “so-and-so family” and other names to call themselves, which should give rise to a high degree of vigilance by the general public, especially those who call themselves the “so-and-so family”, should be highly alert. This should cause the general public to be highly vigilant, especially those who claim to be able to cure all diseases of the “miracle doctor”, and be more careful not to fall into their traps. Third, according to the time, according to the place, according to the person to raise a long and healthy life is not overnight or through a work a method can be realized, the generations of health scientists have advocated that health should be according to the time, according to the place, according to the person to make the best, in order to achieve good results. Such as “spring and autumn frost, do not get sick” this health proverbs, in the use of the “three reasons for the appropriate”. Time, “spring cover” mainly in early spring, must be covered over the “spring cold”, and so the climate is basically stable before gradually reduce clothing; and “autumn freeze” is mainly in the mid-autumn, once you enter the Late fall, you should add clothes in time. Geographically, the north should extend the time of “spring cover” and shorten the time of “autumn freeze”, while the south is the opposite. In terms of the human body, the above content is only for the young and strong and disease-free people, the elderly, children and patients can not be generalized, and the need to strengthen the “spring cover”, not too early to reduce clothing; in the late fall, it is necessary to add clothing as soon as possible, otherwise it will be easy to get sick. In short, in addition to health care, “timing, location, people and” in addition to identification, if you do not ask the yin and yang table, cold and heat, a therapeutic formula, we all eat, inevitably do not have a problem. Fourth, the disease can not avoid medical treatment In a sense, the disease is also a manifestation of life, and life goes hand in hand. It is impossible for people to live forever, and it is also impossible to not be sick for the rest of your life. Facts have proved that the so-called immortality of the magic formula or panacea does not exist. Rather, health care is merely a way of preventing illness by nourishing oneself. However, once sick, you should go to the doctor in time, and listen to the doctor’s advice and arrangements, and actively cooperate, do not avoid medical treatment, will be a small disease into a big disease. Life is at stake, health is priceless. The current “health fever” to have calm thinking, adhere to the above “four principles of health”, learning traditional health concepts and methods, combined with the increasingly mature medical science, so as to achieve the purpose of prolonging life.
