The idea of “treating the disease before it occurs” in Chinese medicine includes two meanings: prevention from health to subhealth and prevention from subhealth to disease, which is called “prevention before the disease occurs” and “prevention after the disease occurs”. This is the so-called “prevention before illness” and “prevention after illness”. According to Chinese medicine, healthy life, behavior and work style are the fundamental methods to improve the quality of life and prevent “sub-health”; the art of health care, such as eating in a disciplined manner, living in a regular manner, regulating emotions and mind, and moderating work and rest, is an effective means to prevent sub-health; adjusting the imbalance of yin and yang is the general guiding principle for the treatment of sub-health. Adjusting the imbalance of yin and yang is the general guiding principle of treating subhealth. 2. Intervention in subhealth: four steps to cure the disease: nourishing the spirit and regulating the mind: the mental state is the primary criterion for measuring a person’s health status. According to Chinese medicine, “calmness and emptiness, the true energy from it, the spirit within the guard, the disease is safe from”, joy, anger, worry, thought, grief, fear, shock and other emotional stimulation is the source of all diseases. Therefore, Chinese medicine has always taken psychological conditioning as the first step in preventing and treating diseases. Reasonable diet: According to Chinese medicine, qi and blood are the material basis of human life activities, and human qi and blood, fluids, essence and blood all come from the biochemistry of the spleen and stomach. If you have a reasonable diet, you will not be sick or lightly ill; on the contrary, you will be very sick or seriously ill. Therefore, Chinese medicine health care should be food-based, food in medicine first. Reasonable diet is the cornerstone of health. Choose natural, fresh, diverse food ingredients, focus on the nutritional balance of the three meals a day, because these are the biggest secret of guarding health. The strength of the body’s positive energy, the condition of blood circulation, the quality of metabolism, the size of resistance to disease, and the speed of treatment and recovery from disease are all related to the constant accumulation of exercise and its effects. According to the differences in human physique, age and gender, exercise prescriptions can be developed to suit the different needs of fitness and disease treatment for various groups of people. Exercise can move all the muscles, muscles and joints, which can relax the meridians, invigorate Yang Qi, and smooth the flow of Qi and blood, and the right amount of exercise is an important means to prevent and eliminate fatigue, and can also make people feel comfortable. Long-term exercise can promote metabolism and enhance physical fitness. Scientific medicine: medicine is three parts poison, scientific and reasonable use of drugs is also one of the methods to protect health. Chinese medicine says “all drugs are poisonous, not just big and small poison is called poison, although licorice, ginseng, can not not be called poison, a long time to take will have a partial victory”, Chinese medicine on the toxic side effects of drugs and drug-derived diseases, is very advanced and scientific, the same is the “cure for the disease” idea of It is also an extension and expansion of the idea of “treating the disease before it occurs”. Appropriate and timely drug intervention can help maintain the physiological functions of the internal organs, but on the contrary, it can cause disease or aggravate the disease. It can be seen that the prevention and treatment of sub-health should be guided by TCM theory and cultivate a healthy way of life, behavior and work, which is manifested by a reasonable dietary structure, cheerful disposition, regular living, and a combination of work and rest, so as to stay away from sub-health and create and maintain a high quality of healthy life.
