Moderator: We know that Dr. Ding is a Chinese medicine practitioner, can you talk about the role and value of water in Chinese medicine and health? Dr. Ding: This is a very good question. As we all know, Chinese medicine attaches great importance to health maintenance, which is also an important measure in the “treatment of future diseases” of Chinese medicine. The so-called “treating the disease before it gets sick” has two meanings, one is “preventing the disease before it gets sick” and the other is “preventing the disease before it gets sick”. These words are all ancient words, which are relatively difficult to understand. In modern language, “preventing illness before it occurs” means preventing the occurrence of illness when there is no illness yet; “preventing changes in existing illnesses” means preventing new complications or further deterioration of the illness when it already exists. Deterioration. So, what kind of knowledge does water have in Chinese medicine or in the production and prevention of diseases? Chinese medicine believes that water plays a very important role in maintaining human health. Dietary substances (including drinking water) in the “water” into the human body through the spleen (spleen main transport), lungs (lungs main regulation of waterways), kidneys (kidneys main water), the bladder (qi) and other internal organs of the metabolism, the generation of nutrients (into the water grain essence), lubrication of the organs or nutrition of the whole body, and the metabolic waste through the urine, perspiration and other means of elimination from the body. Water and grain essence in the body through a variety of different pathways can be transformed into “Jin”, “liquid”, “blood”, “essence “and a series of substances belonging to the “yin class”. Chinese medicine believes that the metabolism of water and the five viscera and six bowels can be related to the most relevant two organs for the kidney and spleen, kidney yang and spleen yang is the driving force of the metabolism of water, when the kidney can not be the main water, the spleen can not be transported to the water and wetness, the body will have water retention, resulting in edema and other diseases. Water belongs to yin in the human body. When there is a lack of water in the body, in terms of Chinese medicine symptoms, it manifests as yin deficiency, which can be kidney yin deficiency, lung yin deficiency, stomach yin deficiency, liver yin deficiency, heart yin deficiency, and occasionally spleen yin deficiency, and so on. The overall understanding of health in Chinese medicine is a balance of yin and yang, and when yin and yang are unbalanced it leads to disease. When there is a lack of water in the body and there is evidence of yin deficiency there are symptoms of yin deficiency and internal heat, such as hot flashes, night sweats, heat in the hands, feet, and heart, dry and astringent eyes, dry mouth, dry stools, palpitations, irritability, and soreness and weakness in the lower back and knees. This is common in elderly patients and those with long-term chronic diseases. Adequate supplementation of water can replenish the body’s “fluid”, through the kidneys into “essence and blood”. Throughout the generations of Chinese medicine health everyone has attached great importance to nourishing “essence”. Chinese medicine believes that “essence”, “gas”, “God” is the body’s three treasures, full of essence, gas, God is a sign of human health, essence loss, gas deficiency, God is a sign of disease and aging. When the human body lacks water, the “essence” is not full, will inevitably lead to aging or disease. Nutrition must pay attention to the “essence”, “essence” will certainly be the right amount of supplemental Yin fluid, that is, water. Chinese medicine emphasizes the harmony and unity of man and nature. As the Yellow Emperor’s Classic of Internal Medicine, “Ling Shu? This God” said: “Therefore, the wise man’s health, we must comply with the four seasons and the appropriate cold and heat; and happiness and anger and peace of mind, the section of the yin and yang and adjust the rigidity and flexibility. If so, the secluded evil does not come, long life and long vision.” “We must comply with the four seasons and adapt to the cold and summer”, in modern layman’s terms: people should comply with the changes of the four seasons of spring, summer, fall and winter, and adapt to the cold winter and summer. Specifically in terms of drinking water, in the summer, the temperature is higher, the body sweats more, we must drink more water. Similarly, after intercourse, due to the consumption of human yin fluid, also need to drink an appropriate amount of water to help yin fluid recovery, yin and yang balance. For middle-aged and elderly people, Chinese medicine believes that “forty and yin gas from half”, often the symptoms of yin deficiency and internal heat, it should also increase the amount of water. Because water is yin, hydration can nourish yin, so, scientific hydration is also an important element of health. Different physique of people drinking water precautions Chinese medicine believes that people are different from each other, that is, people’s physique is different. For the same disease-causing factors, some people get sick, another part of the people do not get sick, get sick people also different severity of the disease, the reason for this difference in traditional Chinese medicine that is because of the human body different. Therefore, for people with different physiques, the methods of prevention and treatment of diseases should also be different. Similarly, people with different physiques should drink different amounts of water. Let me talk about the precautions to be taken when drinking water for people with different physiques. Chinese medicine so-called human constitution is based on the yin and yang five elements, internal organs, essence, blood, fluid and other basic theories to determine the constitution of different people may be different. Chinese medicine on the constitution of the classification of many ways, the most common classification of the constitution is divided into 9 categories: respectively, peace and quality, Yin deficiency quality, Yang deficiency quality, Qi deficiency quality, blood stasis quality, phlegm dampness quality, hot and humid quality, qi depressions quality, endowment quality. So, how to drink water for these 9 different types of constitution is scientific? People with a calm constitution have a basic balance of yin and yang, so the amount of water they drink should be moderate. Yin deficiency people are prone to night sweats, the body of the yin fluid is insufficient, but also prone to internal heat, so the amount of water should be more, it is advisable to drink cool water, in order to nourish the yin and clear the heat. Yang deficiency quality of the body’s Yang Qi is insufficient, can not warm the fluid, the amount of water should be less, it is advisable to drink warm water, in order to warm the fluid. People with qi deficiency and yang deficiency have the same thing, people with qi deficiency often sweat during the day, especially when they are moving, the amount of water should be moderate, it is better to drink more and less, avoid cold drinks, because cold drinks can damage the spleen and stomach. Blood stasis quality people blood viscous, easy to have blood stasis evidence, painful diseases, from the point of view of beauty is also the most likely to appear skin roughness, such people’s drinking water should be large, warm water is better. For people with blood stasis, drinking more water may have the effect of skin beauty. The metabolism of water in the body of phlegm-dampness is abnormal, manifested as thirst, but the amount of water should not be more, a small amount of lukewarm water is better. Damp-heat quality of people in the Guangdong area more, the body of dampness is not transformed, coupled with hot steam, the body often lack of water, but do not want to drink, it is appropriate to drink a small amount of water many times, drinking water on an empty stomach is better. People with qi depressed quality often have liver qi stagnation, drinking water on an empty stomach body fluid circulation, help to dredge the liver and gas. The endowment of people according to the degree of dehydration in the right amount of water is better.
