[What is sub-health]

Sub-health is usually defined as follows: Sub-health refers to some functional changes without organic lesions, also known as the third state or latent disease state. Because of its diverse and unstable symptoms, it is also called "indefinite statement syndrome". It is a transitional stage between health and disease, and there are many uncomfortable symptoms and psychological experiences subjectively.

Sub-health is a new medical thinking. Sub-health is not a disease, but it is a manifestation of modern people's unhealthy body and mind. Sub-healthy people are not strong in physical resistance and psychological quality, and are prone to physical or psychological diseases. Sub-health is a physical state between health and disease, and it is a latent disease state. In this state, although there is no definite disease, the body shows a decline in vitality, reaction ability and adaptability, and there are various disease factors in different degrees, which has a high risk tendency of a certain disease.

At present, about 70% of adults in China are in sub-health state, and among the other 30% people, half are in disease state and the other half are in health state. That is to say, among Chinese residents, only 15% of adults are healthy, and most of them belong to sub-health patients. The occurrence of sub-health is closely related to many negative factors in life and work, such as excessive fatigue, physical and mental overdraft, natural aging of human body, various discomforts in the prophase, recovery period and postoperative rehabilitation period of cardiovascular and cerebrovascular diseases and other chronic diseases, low tide of human biological cycle, unhealthy diet and irregular life.

Sub-health state is an extremely unstable "latent disease state". If we can't pay enough attention to it and improve it actively after it happens, it will easily lead to the transformation from sub-health state to disease state and eventually develop into disease. It can be seen that sub-health will have a very adverse impact on people's health and normal life, and even lead to serious consequences. Therefore, we must attach great importance to and actively guard against sub-health psychologically and in action. This not only requires people to establish good lifestyles and habits, strengthen physical exercise, but also strive to enhance their psychological quality and protect their mental health, so as to maintain their physical and mental health, and then keep themselves away from sub-health.
