What is health? How can we achieve health and longevity? From ancient times to the present, this is a question that people have been exploring constantly. Emperors of past dynasties tend to pamper themselves and lead a good life. Many people seek immortality, but few people live a long life. Today, with the continuous progress of science and technology, various "civilization diseases" have appeared in cities. Why is it that everyone ignores that health does not depend on only one factor?

Modern medicine believes that human health is the overall health, including physical health, mental health, environmental health and many other aspects. Like other things, health is the unity of multiple contradictions. If we deviate from the balance and focus on one side, it will intensify contradictions, from sub-health to disease. The key to staying healthy is to find the balance of contradictions.

The golden mean is the core of Confucianism and the essence of China traditional culture. It opposes "over" and "under", and demands to grasp a middle point between the two ends, that is, impartiality, impartiality and just right, so as to keep things normal. The golden mean of ancient people's health preservation is the balanced health preservation method.

Balanced health care is a new health care theory put forward by Chinese medical experts in recent years on the basis of summarizing ancient health care and traditional medicine in China and combining modern medicine. It follows the natural law of the development of all things in the world, and according to the functional characteristics of human tissues and organs, it starts from many aspects, such as nutritional balance, dynamic and static balance, psychological balance, yin-yang balance, environmental balance, acid-base balance, etc., to achieve comprehensive health care and comprehensive health preservation, thus achieving the health care effects of strengthening the body, eliminating diseases and prolonging life.

Health is the foundation of quality of life and the most precious wealth in life. But in modern society, competition, pressure, all kinds of pollution, lack of exercise, unbalanced nutrition, changes in living environment and so on, too many factors make human health out of balance. At the same time, the special physiological stage will also make the human body in a short-term unbalanced state. These circumstances require us to rely on scientific and practical health preservation methods, constantly seek and create balance in the imbalance, and then maintain balance, so as to seek lifelong health.
