What is the difference between health and sub-health?

The so-called sub-health state, in layman's terms, refers to a state of low quality and psychological imbalance without clinical symptoms and signs, or symptoms without clinical examination evidence, but with information of potential onset tendency. Generally speaking, the sub-health state consists of four elements: fatigue and weakness excluding the causes of diseases, intermediate state or pre-illness state between health and diseases, imperfect state in physiology, psychology, social adaptability and morality, and declining state of organizational structure and physiological function that is not commensurate with age. To understand sub-health scientifically, it is necessary to distinguish sub-health from related medical problems: First, sub-health is different from subclinical: although sub-health overlaps with upstream health status and downstream disease status, the distinction is also obvious. Subclinical is subjective examination evidence without obvious clinical manifestations, such as subclinical carotid atherosclerosis in middle-aged and elderly people, obvious carotid intima-media thickening and even plaque formation without clinical manifestations; However, people in sub-health state complained of headache, dizziness and chest discomfort, but there was no abnormality in vascular echocardiography and electrocardiogram. Second, sub-health is not equal to chronic fatigue syndrome (CFS). First of all, CFS has an international unified standard, but sub-health has not; Secondly, the incidence of CFS in adults over 18 years old is only 0.004%, while the incidence of sub-health is 70%, which is very different. Furthermore, most of the sub-health states described in China can be recovered through active intervention, while only 30% of CFS can be recovered. Third, the definition of sub-health should also be distinguished from clinical functional diseases, mental and psychological disorders and early diagnosis of some diseases. It should be pointed out that there is no unified judgment standard for sub-health at present, and there are also great differences in the understanding and definition of sub-health between Chinese and western medicine. These are all problems to be studied and solved in the future. How to define sub-health is rich in connotation and extensive in extension. It can be said that the scope of the concept of health is as large as the coverage of sub-health; The spectrum of sub-health is as wide as the spectrum of diseases and symptoms. Summarizing the research results of our center in recent years and the opinions of most experts, the classification and main contents of sub-health can be summarized as follows. 1. Sub-health can be divided into: (1) Physical sub-health according to the new concept of health of WHO. The main manifestations are physical fatigue, weakness, general malaise, sexual dysfunction and menstrual cycle disorder for unknown reasons or excluding diseases. (2) Mental sub-health. Mainly manifested as unexplained mental fatigue, emotional disorders, thinking disorders, panic, anxiety, inferiority, tension, indifference, loneliness, impatience, and even suicidal thoughts; (3) The social adaptability is sub-healthy. Outstanding performance is that it is difficult to adapt to work, life, study and other environments, and it is difficult to coordinate interpersonal relationships, that is, role dislocation and inadaptability are the concentrated manifestations of social adaptive sub-health; (4) Moral sub-health. Mainly manifested in the world outlook, outlook on life and values, there are obvious deviations that harm others and do not benefit themselves. 2. According to the constituent elements of the sub-health concept, (1) the "indefinite statement syndrome" which is physically and mentally uncomfortable but difficult to diagnose; (2) Pre-clinical manifestations of some diseases (pre-disease state); (3) "Unexplained syndrome" whose pathological significance is difficult to be defined at the moment, such as menopause syndrome, neurasthenia syndrome, fatigue syndrome, etc. ; (4) the carrying status of some pathogens, such as hepatitis B pathogen carriers, tuberculosis carriers and some virus carriers; (5) The high and low limits of some clinical examinations, such as high blood lipid, blood pressure and heart rate, and low blood calcium, potassium and iron; (6) High risk factors, such as overweight, smoking, excessive tension, dyslipidemia, hyperglycemia, hypertension, etc. 3. According to the organizational structure and system organs of the body, it can be divided into sub-health states such as neuropsychiatric system, cardiovascular system, digestive system, bone and joint system, genitourinary system, respiratory system and special feeling. What should we pay attention to in the prevention and treatment of sub-health? The survey shows that the incidence of sub-health population in China is between 45% and 70%, and the age of occurrence is mainly between 35 and 60 years old. The distribution characteristics of the crowd are as follows: middle-aged intellectuals, white-collar workers, leading cadres, entrepreneurs and movie stars, who are mainly engaged in mental work, have a high incidence of sub-health. The sub-health problems of adolescents are worrying, the sub-health problems of the elderly are complex and changeable, and the sub-health problems of special occupations are prominent. Sub-health has four major causes: 1. Excessive tension and stress. Studies have shown that long-term stress and stress have four major hazards to health: first, acute and chronic stress directly damages the cardiovascular system and gastrointestinal system, leading to stress ulcer, elevated blood pressure, accelerated heart rate, accelerated arteriosclerosis and cardiovascular events; Second, it causes brain stress fatigue and cognitive decline; The third is to destroy the biological clock and affect the quality of sleep; Fourth, the decline of immune function leads to the increase of malignant tumors and infection opportunities. 2. Bad lifestyle and habits. Such as high salt, high fat and high calorie diet, heavy smoking and drinking, sedentary and so on are the most common reasons for sub-health. 3. The adverse effects of environmental pollution. Such as water and air pollution, noise, microwave, electromagnetic waves and other chemical and physical factors pollution is a hidden killer of health. 4. Bad mental and psychological factors. This is one of the important factors of sub-health of body and mind. Sub-health has five major hazards: 1. Sub-health is the pre-illness state of most chronic non-communicable diseases, and most malignant tumors, cardiovascular and cerebrovascular diseases and diabetes are transferred from sub-health people. 2. Sub-health status obviously affects work efficiency, quality of life and study, and even endangers the life safety of special operators, such as aerial workers and competitive sports personnel. 3. Mental sub-health can easily lead to mental illness, even suicide and family injury. 4. Most sub-health states have causal relationship with biological clock disorder, which directly affects sleep quality and aggravates physical and mental fatigue. 5. Severe sub-health can obviously affect the healthy life span, and even lead to early death, early illness and early disability. In view of the causes and harm of sub-health, we must strengthen self-protection and keep in mind the "cross policy" of preventing sub-health: 1. "Peace of mind" means balanced psychology, peace of mind and calm mood; 2. "decompression", that is, timely relieving excessive tension and pressure; 3. "Clockwise" means adapting to the biological clock and adjusting rest and sleep; 4. "Enhance immunity", enhance your immunity through aerobic exercise; 5. "Improvement" means to stop the occurrence of sub-health from the source by changing bad lifestyles and habits. Comment: Sub-health is not a market label. In recent years, with the emergence of new health concepts, the concept of "sub-health" seems to be the label of marketing promotion for a time. Various sub-health institutions and sub-health products have sprung up, such as "sub-health testing center", "sub-health clinic" and "sub-health products". However, behind the lively phenomenon, because the concept of sub-health has not been clarified, it entered the market prematurely, was hyped up, and was immediately commercialized and industrialized, which made many businesses sell so-called sub-health services and products everywhere under the label of sub-health without even knowing what it is. This has created ideological confusion for many people and created a bad impression on the concept of sub-health. Sub-health is coming, but people's understanding is confused and they worry too much, but their health is not guaranteed. This makes sub-health become a label of market behavior in a great sense, rather than a scientific concept. In this regard, medical care and health education experts believe that top academic research institutions and industry platforms should be set up at the national level as soon as possible, and professional research teams and organizations should be set up to study and unify the concept, connotation and definition scope of sub-health, so as to provide theoretical basis for the final formation of unified sub-health evaluation standards and norms; Relevant departments should aim at improving people's health quality and quality of life, coordinate and organize the investigation and analysis of sub-health epidemic characteristics, study relevant intervention schemes and measures, and provide theoretical and technical support for formulating national health promotion plans. Experts stressed that sub-health is not a market "label", and sub-health research is a science.
