Several manifestations of sub-health:
(1) Functional changes, not organic lesions. (2) Signs change, but the existing medical technology can't find the lesions. (3) Poor quality of life and low health level for a long time. (4) Unhealthy signs of chronic diseases outside the lesion site. Whether sub-health develops into a serious organic disease is uncertain. However, sub-health itself is a problem that needs to be solved.
2. Health means that a person is in good physical, mental and social condition. The traditional concept of health is "disease-free health", while the modern concept of health is overall health. The World Health Organization puts forward that "health is not only the absence of physical diseases, but also mental health, good social adaptation and morality". Therefore, the health of modern people includes: physical health, mental health, mental health, social health, intellectual health, moral health, environmental health and so on. Health is the basic right of human beings and one of the most precious wealth in life. Health is the basis of quality of life; Health is an important aspect of human self-awakening; Health is the best state of life, with rich and profound connotations.
