People in sub-health state, can not achieve the standard of health, performance for a certain period of time decreased vitality, functional and adaptive symptoms, but does not meet the modern medical disease related clinical or sub-clinical diagnostic criteria.

The detection rate of sub-health is different in different sex, age and occupation, and has nothing to do with place of birth and nationality. Generally, the detection rate of women is higher than that of men, 40-50 years old is higher than other age groups, teachers, civil servants.

The main causes of sub-health are unreasonable diet, lack of exercise, irregular work and rest, lack of sleep, mental tension, psychological pressure, long-term bad mood and so on.

The main characteristics of sub-health include:

① The symptoms reflected by the feeling of physical and mental inadaptability, such as fatigue, weakness, mood changes, etc., are difficult to be clear in a considerable period of time;

(2) various manifestations of weakness caused by age-incommensurate organizational structure or physiological function decline;

(3) micro-ecological imbalance;

Clinically, the above three sub-health manifestations often appear together.

Some scholars believe that sub-health is the same as chronic fatigue syndrome abroad, which is the study of a group of somatic and psychological symptoms mainly characterized by chronic fatigue, but some scholars hold different opinions.
