First, conform to nature. Life exists in nature and is closely related to it. With the change of nature, the human body will change accordingly. Such as sweating in summer and dry skin in autumn; Different water and soil environments will lead to different living habits of people. If we don't understand this truth, we can do whatever we want, and our bodies can't adapt to the changes in nature, so diseases will follow. Some people wear less clothes in winter for fashion, which leads to colds and sore joints; Some people incubate air conditioners for a long time in summer just for comfort, and finally they get "air conditioning disease". Only by understanding the changing laws of nature, making people's daily life, thoughts and behaviors adapt to the various changes of nature at any time, and maintaining the coordination inside and outside the body, can we prevent diseases, protect health and be conducive to longevity.

Second, the form of movement is like a house of life activities. It contains essence, qi and spirit, and maintains the life activities of the human body. The body is also an important barrier for people to resist external evils. People's fur, skin, blood, bones and internal organs all have the function of resisting external evils. Therefore, health care and disease prevention must pay attention to the adjustment of body shape. "Lu's Spring and Autumn Annals" said: "Running water does not rot, and relatives do not bite and move. So is Qi. If the shape does not move, the essence will not flow, and if the essence does not flow, it will be depressed. " It explains the reason of dynamic shape to prevent stagnation of essence. Exercise can also enhance the function of the spleen and stomach, which is helpful to qi and blood transformation. The longitudinal research on the elderly with long life shows that most people who insist on moderate physical activity or physical exercise can live independently after 90 years old.

Third, regulating healthy qi means keeping the body full of healthy qi and keeping the normal activities of the body.

Chinese medicine believes that qi is the most basic substance that constitutes the human body and maintains human life activities. Qi fills the whole body and runs endlessly, promoting and stimulating various physiological activities of the human body. The rise and fall of qi and its normal operation determine the strength and life span of human body. If daily life violates the changes of the four seasons, it will cause the dissipation of qi or the obstacle of qi operation; Overwork and indulgence can lead to qi deficiency; Excessive behaviors such as lying down for a long time and sitting for a long time often cause qi stagnation; Improper diet will also hurt the gas; Emotional disorder is the most prone to depression. In addition, excessive use of tonics often hurts vital qi invisibly.

Fourth, protecting yin essence refers to kidney essence, including essence of other viscera. Traditional Chinese medicine regards essence as the basic substance that constitutes the human body and promotes the growth and development of the human body.

5. Keeping God here refers to spiritual thinking activities. To keep healthy, we should keep quiet in our mental and thinking activities. Generally speaking, people live in society, and their spiritual thinking activities are often disturbed, so it is difficult to be quiet. Improper use of spirit, long-term excessive or sudden intense emotional activities exceed the human body's ability to adjust and adapt, which will consume essence, cause disorder of qi and blood operation, imbalance of yin and yang, and damage to viscera. Therefore, from the perspective of health preservation and disease prevention, we should always keep the spirit quiet and hide it in our hearts. Only in this way can the essence, qi and shape be well conditioned. Spiritual feelings should always be pleasant, avoiding impatience, worry, sadness, surprise, anger and other bad emotions. Regular meditation, listening to music, painting and calligraphy and other artistic activities can have a good regulatory effect. Therefore, keeping the spirit silent is not passive and avoiding the world, but advocating the rational use of spirit, which has a positive effect on the body.
