The purpose of health care is to cultivate vitality, prevent diseases and strive for a long and healthy life. During the two Han dynasties, the culture of health maintenance was quite prevalent. There are about four main methods of health maintenance: 1) food consumption, i.e., refining of mercury and such like internal consumption; 2) grain prevention, i.e., gradually reducing food to completely cut off water and grain diet; 3) gas consumption, equivalent to today’s qigong, practicing whistling and exhaling; 4) guidance, equivalent to today’s dynamic gymnastics or gymnastics, of course, there are many movements that imitate animals. This kind of fitness exercise has been very popular in the Han Dynasty, such as the 1982 Changsha Mawangdui No. 1 Han tomb unearthed guide map is the earliest record found today. Exercise for health means: to maintain health, enhance physical fitness and delay aging by moving the body. Traditional exercise for health is characterized by the theories of yin and yang, internal organs, qi and blood, and meridians in Chinese medicine, and is characterized by nourishing the essence, practicing qi, and regulating the spirit, with emphasis on the coordination of intention, whistling and body movement. The water does not rot, the pivot does not moth-eaten, the traditional movement of health, after generations of health practitioners continue to summarize and supplement, gradually formed the movement of limbs, self-massage to practice shape, whistling and exhalation, adjust the nose to practice gas, quiet thoughts, eliminate distractions to practice health care methods. Specific exercise methods are as follows: exercise time should be in line with the growth of Yang Qi, choose the right time to exercise will have a good effect with half the effort. Chinese medicine put forward the “unity of heaven and man” concept, that people’s life rules must be in line with the four seasons, in line with the characteristics of different times to exercise to maintain health, so as not to cause disease. In the year, Yang Qi is born in spring, grows in summer, harvests in autumn and hides in winter, so we should pay attention to the rise of Yang Qi and protect it. In the spring season, we can exercise more to stretch the body’s Yang Qi and circulate Qi and blood, which is conducive to the production of Yang Qi. In winter, Yang Qi is “collected” to “hidden”, so you should reduce exercise, get up late and go to bed early to nourish your body and mind, so that Yang Qi can be hidden. The same applies to the day. The morning is like spring, the daytime like summer, the evening like autumn, and the evening like winter, so you should adjust your body’s activities according to the growth and changes of yang qi and follow nature. The intensity of exercise should be moderate. Hua Tuo once said, “The human body wants to get labor, but it should not make extreme ears.” This means that the exercise for fitness purposes must be within the appropriate limits, not too much, but moderate, then the circulation of blood and vital energy; moving too much, then the blood and vital energy boiling, but the depletion of true qi. In short, the amount of exercise varies from person to person, with the body fever as appropriate, such as fatigue and weakness after exercise, poor appetite, etc. indicates that the exercise is excessive. Exercise varies from person to person, for the elderly or patients, due to muscle strength decreases, the nervous system response is slower, poor coordination, it is appropriate to choose slow and gentle movements, muscle coordination and relaxation, the whole body can be active exercise, such as walking, taijiquan, eight duanjin, Yijinjing, five avian play, etc.. For young and strong people with good health, you can choose exercise programs with a large amount of movement, such as long-distance running, playing basketball, soccer, martial arts, etc.
