I don't know when Evodia rutaecarpa started drinking eight glasses of water every day, which has become the first choice for fashionable women and beauty lovers. It is said that it has a good effect of nourishing yin and detoxifying. Therefore, "eight glasses of water" has become our way of keeping in good health, and many people are insisting on it. Sometimes we can't help asking, "Is it really useful to drink so much water? Why did you drink so much water, and your body didn't get any better except your stomach swelled? Nourishing yin in traditional Chinese medicine actually refers to improving the nourishing function of viscera and limbs and supplementing body fluid and essence and blood. The so-called vaginal fluid, its composition in the human body is very diverse. The blood and bone marrow that we are familiar with, the tears, snot and saliva that we don't pay much attention to every day, and the yin that we can't see to maintain the normal function of the internal organs all belong to this category. These yin fluids together constitute the category of "yin" in our body. Therefore, it is very different from the concept of water. In other words, the water we ingest through products that tonify yin, such as diet, can't directly constitute the vaginal fluid of human body, and drinking more water can't directly tonify yin. Because the water absorbed from the outside does not directly constitute the composition of the human body, it cannot achieve the effect of instantly replenishing yin. In addition, the human body's absorption of water is limited. Excessive water intake can not only achieve a good effect of nourishing yin, but also increase the burden on the kidneys and cause unnecessary water retention. This will inevitably lead to excessive consumption of yang, because excessive discharge of water depends on the evaporation of yang, and excessive water evil will naturally lead to excessive consumption of yang and water retention.

Under the tide of commodity economy, we are sometimes dazzled by all kinds of drinks on the shelves of shopping malls: pure water, mineral water, supplementary drinks that claim to be completely consistent with human body fluids, and brightly colored juice drinks ... It seems that our demand for water is so urgent, and there are still so many nutrients that must be supplemented by drinking water. To paraphrase an advertisement, "Milk, juice and vegetables can be supplemented by drinking water. Sometimes, it's just a beautiful expectation. We rely too much on bottles of pills to replace all kinds of nutrients that should be obtained through normal diet. If there is a pill that can cover the fruits and vegetables we need in a day, then we don't have to eat fruits and vegetables. The answer is of course no, so we can't expect to replace other nutrients with drinks. Sometimes, the sales gimmicks of merchants can easily make us fall like clouds. Everyone should be careful when consuming in front of all kinds of water and drinks, and don't put your hand into your pocket easily. What we really need is to simplify things in life as much as possible and give us a glass of water. Drink a proper amount of water every day, not a fixed amount. People who are strong and consume a lot can drink whale wine to their heart's content, and sisters who are weak and have little labor can also sip it slowly. Sour plum and iced pear can relieve summer heat, but please don't drink too much; Milk and coffee can melt the winter cold, but don't overdo it. The amount of water you drink varies from person to person. Generally speaking, the daily water consumption should be at least in balance with the water consumption in the body. The amount of urine excreted by human body in one day is about 1500 ml, and the total consumption is about 2500 ml with the water evaporated from feces, breathing or skin, while the water that human body can replenish from food and body metabolism every day is only about 1000 ml. Therefore, normal people need to drink at least1500ml of water every day. Usually, how much water each person needs to drink varies according to the amount of activity, the environment and even the weather. Drinking more water for normal people will not have much impact on the body, but it may lead to increased urination and inconvenient life. However, for some special ethnic groups, we must pay special attention to the amount of drinking water. For example, patients with edema, heart failure and renal failure should not drink too much water, because drinking too much water will increase the burden on the heart and kidneys and easily lead to aggravation of the disease. For patients with heatstroke, cystitis, constipation and dry skin, drinking more water can play a certain role in relieving the disease. In addition, people should drink more water when they have a cold and fever, because rising body temperature will cause water loss. Drinking more water can promote body heat dissipation and help patients recover. Pregnant women and people who exercise a lot consume a lot of water and should drink more water. Warm water is the best drink. Experts say that from a health point of view, boiled water is the best drink. Does not contain calories, and can be directly absorbed and utilized by the human body without digestion. It is generally recommended to drink warm water below 30 degrees Celsius, which will not cause gastrointestinal peristalsis and vasoconstriction. Sugary drinks will slow down the absorption rate of water in gastrointestinal tract, and long-term consumption of sugary drinks will have a certain adverse effect on human metabolism. Although sugary drinks such as orange juice and cola taste good, they should not be drunk too much. The daily intake should be controlled at about one cup, and the maximum intake should not exceed 200 ml. For diabetics and obese people, it is best not to drink such drinks. Bottled water, such as pure water and mineral water, is favored by modern people because of its convenient drinking. However, when drinking this water, it is necessary to confirm the sanitary conditions during production. It is best to drink a bucket of water within a month, and pure water should not be the main drinking water. Because water is one of the six nutrients in human body, it contains many minerals and trace elements beneficial to human body, but the content of these substances in pure water is greatly reduced. If people's diet and nutritional structure are unbalanced, it will easily lead to nutritional imbalance. Some people worry that the hardness of tap water is too high, which will be harmful to health. Actually, this is a wrong concept. The results of modern scientific research show that the hardness of water has little influence on human health, and now tap water in China meets the drinking water standard, so it is safe to drink boiled tap water. Tea and coffee are refreshing. Drink light tea when drinking tea, and avoid drinking coffee. Caffeine can affect the absorption of calcium. Don't gulp when drinking water. Many people often think of drinking water when they are thirsty, and often swallow it in one gulp. This is also wrong. Drinking water too fast and too hard is bound to swallow a lot of air together, which is easy to cause hiccups or bloating. Therefore, it is best to put water in your mouth first, and then drink it slowly, especially for people with weak stomach and intestines. As for the time to drink water, experts remind: don't drink water when you are thirsty. Drink water in moderation between meals, preferably once every hour. People can also judge whether they need to drink water according to the color of urine. Generally speaking, human urine is light yellow. If the color is too light, maybe they drink too much water. If the color is too dark, it means they need to add more water. Drinking less before going to bed and drinking more before going to bed is also the principle of drinking water correctly, because drinking too much before going to bed will cause eyelid edema, half a nightclub running to the toilet and poor sleep quality. After a night's sleep, the body loses about 450 ml of water, which needs to be replenished in time after getting up in the morning. Therefore, drinking a glass of water on an empty stomach after getting up in the morning is beneficial to blood circulation, and can also help the brain to wake up and make the thoughts of this day clear and agile. What water can't be drunk 1. Raw aquatic water may contain all kinds of bacteria, viruses and parasites harmful to human body, which is easy to cause acute gastroenteritis, viral hepatitis, typhoid fever, dysentery and parasitic infection, and is very harmful to health. 2. aged water aged water is commonly known as "stagnant water", that is, water that cannot be stored for a long time. Drinking this kind of water often will obviously slow down cell metabolism for minors and affect the growth and development of the body; Middle-aged and elderly people will accelerate aging. According to medical experts, the incidence of esophageal cancer and gastric cancer is increasing in many places, which may be related to long-term drinking of aged water. The tap water that people drink is disinfected by chlorine. Thirteen kinds of harmful substances can be separated from water treated with chlorine, among which halogenated hydrocarbons and chloroform can also cause cancer. When the water temperature reaches 100℃, these two harmful substances will be greatly reduced with the evaporation of steam. If you continue to boil for three minutes, you can safely drink.
