It is a transitional stage in the process of transformation from health to disease. It is a comprehensive manifestation of abnormal physiological activities of the body, a functional change that has not yet reached organic change, and an early reflection of the abnormal adjustment of the body and mind as a whole. There are four major causes of sub-healthy state: (1) adverse mental and psychological stimuli such as excessive tension and stress. (2) Poor lifestyle such as high salt, high fat and high calorie diet, heavy smoking and alcohol consumption, and sedentary lifestyle without exercise. (3)Bad environmental factors such as: water and air pollution, noise, microwave, electromagnetic waves, pesticides and other physical and chemical pollution. (4) Bad attitude towards life: such as various desires that cannot be realized. Common manifestations of subhealth state Common manifestations of subhealth include: headache, dizziness, insomnia, easy fatigue, poor appetite, bloating, constipation, frequent colds, abnormal sweating, back pain, gray face, dry eyes, rough skin, heavy head and sleepy, sores on the mouth and tongue, cold hands and feet, or feverish hands and feet, nervousness and anxiety, irritability, dreamy and easy to wake up, etc.; other pathogenic factors such as smoking, alcoholism, gluttony, etc. and other abnormal pathological states such as overweight, fatty liver, dyslipidemia, high blood sugar and blood pressure. If effective interventions are not taken and the factors that cause subhealth cannot be avoided, the subhealth state will persist and accumulate to a certain extent, leading to the occurrence of diseases. Chinese medicine is a unique theoretical system that is guided by a holistic concept and is characterized by evidence-based treatment. It has an all-round advantage over modern medicine in terms of understanding the nature of subhealth and diagnostic and treatment methods. By combining herbal medicine with acupuncture, moxibustion, gua sha and other comprehensive treatment methods, TCM can effectively improve the state of subhealth and promote the body to return to a healthy state as soon as possible.
