Laozi said in the Tao Te Ching: "Quiet is the right thing in the world", "Clear but not miscellaneous, static and unchanging, governing by doing nothing, and moving to the sky, this is also the way to nourish the heart." "Neijing" also said: "Nothing is indifferent, the true qi will follow, and the spirit will be hidden inside. Is it safe? It is old and idle, fearless, tired and tireless, obedient, obeying your own desires and getting what you want. " Advocating quietness without distracting thoughts, leisure without desire, that is, preventing improper thoughts.

Influenced by Taoism and Buddhism for a long time, later generations advocated "cultivate one's morality and cultivate one's nature", "everything is empty", paid attention to "meditation" and "quietness", and often adopted the methods of restraining eyes and nourishing ears to make people's eyes clear and not tired. Although it is negative and unrealistic to overemphasize "ignore what you will hear and keep your head quiet", it is certainly beneficial to health and longevity to restrain your eyes and ears from external bad stimuli and try to avoid contact with those bad stimuli.

Sun Simiao advocated that on weekdays, "we should not talk nonsense with our ears, our mouths, our bodies and our hearts". We have no big emotions, no big intentions, no big thoughts, no singing, no crying, no sorrow, no celebration and no drinking. Calm and quiet, not pursuing too much, not forcing yourself to do things beyond your power, so as to maintain the essence of the human body and enjoy the happiness of old age.

In fact, after the Ming Dynasty, Taoism summarized the previous health care methods, and then changed from static health care to dynamic health care. Qigong, which embodies this view, is actually moving silently, guiding the spirit around the whole body purposefully, and achieving the purpose of running qi and blood, reconciling yin and yang, keeping yin and yang secret, spiritual and even.

More comprehensively, "life lies in exercise and rest". During exercise, metabolism increases, decomposition and oxidation accelerate, which can prevent obesity caused by excessive accumulation of fat and enhance the functions of various organs. When resting, nerves are relaxed, breathing, heart rate, blood pressure and body temperature are correspondingly reduced, metabolism is reduced, reduction and synthesis are dominant, and energy is stored. This cumulative effect is helpful to repair damage, improve health and prolong life. Motion and static are the unity of opposites. Exercise without rest, or rest without exercise, cannot keep the balance of Yin and Yang of the body.
