Mental health preservation refers to purifying people's spiritual world, automatically eliminating greed, changing their bad personality, correcting the wrong cognitive process, adjusting their emotions, making their mentality peaceful, optimistic, cheerful and open-minded, so as to achieve the goal of health and longevity. Mental health preservation method is equivalent to the mental health care method of modern medicine. ? Traditional health preserving theory emphasizes the theory of "unity of form and spirit". The so-called "form" is the form, which refers to the human body, while "spirit" has broad and narrow meanings. God in a broad sense refers to the external manifestations of the whole human life activities, including all the exposed signs of physiology or pathology. God in a narrow sense refers to people's spiritual consciousness and thinking activities.

The unity of form and spirit means the unity of form and spirit. Form is the material basis of God, and God is the life expression of form. Only the unity of form and spirit can achieve the goal of health and longevity. Traditional Chinese medicine believes that God is the master of life activities and can direct the functional activities of human organs and tissues, and puts forward the theory of "the relationship between form and spirit", which holds that human physiological functions are closely related to mental activities, and mental factors can directly affect the functional activities of viscera, yin, yang, qi and blood. If a person is cheerful, cheerful, optimistic about life, peaceful yin and yang, smooth blood and harmonious internal organs, his body will naturally be in a healthy state. On the other hand, bad mental state can directly affect the function of human viscera, resulting in dysfunction of viscera, obstruction of qi and blood circulation, decline of disease resistance, weakness of vital qi and easily lead to various diseases.

Modern medical research has also confirmed that psychological factors have a great influence on physical health. People with open mind and optimistic personality have the best neuroendocrine regulation system and normal immune function. People with unhealthy psychology have disordered neuroendocrine function and decreased immune function, and the incidence of diseases is obviously higher. For example, the incidence of hypertension and coronary heart disease in people with impatient behavior A is 2 ~ 3 times higher than that in people with calm behavior B, and the mortality rate is 7 times higher; Emotional depression can also cause a significant decline in human immune function, prone to infectious diseases and tumors. Therefore, mental health preservation is of great significance in the prevention and treatment of psychosomatic diseases.
