Why do people drink 8 glasses of water every day?
How many glasses of water is the most suitable for drinking every day? Water is closely related to our life. But do you know how much water to drink every day is reasonable? Do you know when drinking water is best for your health? In the colorful "water" world, which kind of water is best for your physique? How should different people drink water scientifically? Here, we will present the "2004 Drinking Water Collection" for you. Core Tip ● Adults need at least 2 liters of water every day ● Children should drink 1 liter every day ● It is best for the elderly to drink less water and drink more times. As we all know, water is the source of life. But do you all know the reasonable quantity and know-how of drinking water? Experts from Asia-Pacific International Functional Water Cooperation Organization remind consumers that 8 glasses of water a day is essential, and adults should drink water at least 6 times a day. In a word, people should form the habit of drinking water regularly. It is reported that in order to maintain normal and healthy metabolism, Chinese adults must supplement about 2 liters (1 liter = 1 liter) of water every day, which is about 7 to 8 cups of water (including water supplemented from diet). Children should drink about 1000 ml of water every day. It is worth emphasizing that everyone should develop the habit of drinking water regularly, and never wait for thirst before drinking water. Wait until you are thirsty before hydrating. In fact, the human body is already short of water. At the same time, pay attention to the time and method of drinking water. Generally speaking, you should drink 1 ~ 2 glasses of water every morning, noon and evening. When drinking, it is best to drink slowly and carefully, which will help people to detoxify and maintain beauty and feel refreshed. Don't drink water that is too hot. Some people like to drink cold water, while others like to drink hot water. Usually they mistakenly think that the hotter the water, the better, but it is not. Experts remind everyone that drinking fresh boiled water should not be too hot, and it is generally appropriate to drink 25 degrees Celsius to 30 degrees Celsius. Is drinking water a magic weapon for women to lose weight? Many people worry about the calories, calories and weight of food every day, but German scientists have found the simplest way to lose weight, that is, drinking 2 liters of water every day helps to burn calories and achieve the purpose of losing weight. A study by Charite University in Berlin, Germany, found that those who follow the health advice and drink 2 liters of water a day (about 250 ml per cup, or about 8 cups) can burn an extra 150 calories a day. Michael Boschmann, a professor in charge of this research, said that water can stimulate sympathetic nerves to regulate metabolism, improve the metabolic efficiency of the body, and achieve the effect of burning more calories. However, some nutritionists are cautious about this "brand-new" discovery, and emphasize that weight loss should also pay attention to nutritional balance. Drinking 2 liters of water a day is indeed a healthy way to help the body's metabolism. It is everyone's daily need for the elderly to drink plenty of water to prevent aging and drink healthy and safe water. But for different people, water has different meanings. Many elderly people do not have a strong desire to drink water. They always think that they can drink less water if they exercise less and sweat less. In fact, once people reach middle-aged and old age, the water in cells will be reduced by as much as 30% to 40% compared with when they were young. For this reason, most middle-aged and elderly people will have wrinkles. If they can't fully replenish water, not only skin wrinkles will be aggravated, but also normal urination will be affected. Therefore, the elderly actually have an urgent need for water replenishment. In fact, there are many ways to replenish water. The suggestions of authoritative nutritionists are: cooking vegetables and fruits, drinking tea (strong tea is not suitable), drinking cold boiled water and so on. It is worth noting that it is very helpful for the elderly to drink a cup of cold boiled water after getting up in the morning. Because after a night's sleep, the human body consumes a lot of water from sweating, urination and breathing, the blood thickens, and the vascular lumen narrows due to the decrease of blood flow. This can easily lead to accidents such as cardiovascular and cerebrovascular embolism. The elderly are the high-risk population of this kind of disease. Therefore, timely and appropriate water supplementation can not only reduce blood viscosity, promote vasodilation, but also clean gastrointestinal tract, thus helping digestion and preventing constipation. As for the amount of drinking water, it depends on the physical condition of the elderly, and it is best to drink less and more times. For the elderly, the amount of drinking water at a time should not be too much, so as not to increase the burden on organs such as the heart and kidneys; In addition, middle-aged and elderly people should not drink a lot of water after work or exercise, although they sweat a lot. Five "identities" of drinking water When we realize the importance of drinking water, it becomes very important to find the water that suits us best. What are all kinds of drinking water on the market at present? Let's look at the definition given by experts. ● Pure water: The drinking water passing through the membrane separation and filtration device filters out harmful substances in the water on the one hand, and minerals and trace elements beneficial to the human body on the other. ● Clean water: The drinking water filtered by activated carbon will retain beneficial elements such as minerals while filtering harmful substances, but the filter element must be kept clean and replaced regularly to ensure the stability of water quality. ● Mineral water: Drinking water collected from underground water flowing through rocks deep underground and treated to some extent is characterized by containing certain minerals and trace elements, which is beneficial to human metabolism. What is a good mineral water? Consumers should pay attention to the ion content in the water printed on the trademark. Generally, the combination of high calcium and low sodium is the top grade, and the contents of trace elements such as magnesium, potassium and sulfate will also be marked. ● Oxygen-enriched water: Oxygen-enriched water is artificially oxygenated water. However, it should be noted that the dissolution of oxygen in water is saturated, and the more the better. ● Distilled water: After water is boiled to the boiling point of 100℃, harmful substances with boiling point lower than 100℃ will remain while sterilizing at high temperature. For example, carbon tetrachloride with a boiling point of 70 degrees Celsius cannot be filtered out. Seven Standards for Healthy Drinking Water Although the types of water are different, the functions of drinking water are also different. But what is healthy and beneficial drinking water still has principles to follow. Last year, experts in the industry formulated seven standards for healthy drinking water: ● No toxic, harmful or odorous substances; ● Moderate hardness; ● The mineral content required by the human body is moderate; ● The pH value is slightly alkaline; The content of dissolved oxygen and carbon dioxide in water is moderate; ● Small water mass; ● Water has a strong physiological function. Drinking schedule The really effective way to drink water is to drink a whole glass of water (about 200-250 ml) in one breath, not just twice, so that the body can really absorb it. Of course, you don't have to drink it all at once. If you just take a sip or two to "quench your thirst", it will not help your body at all. Drink good water, try to avoid drinking distilled water frequently (generally distilled water is too acidic, which is easy to cause harm to the body, especially to people with weak kidneys), and you can choose high-quality mineral water. If possible, drinking alkaline water is most beneficial to the human body; Otherwise, there is no need to cook after filtering with a household water filter. Generally speaking, if there is no choice, drinking is better than not drinking! ! Drinking warm water is hot in summer, so many people will choose to drink ice water or add ice to the water. In fact, ice water is not good for the function of the stomach, and drinking warm water is more beneficial, because it is especially helpful for the body to absorb and utilize, and it is more helpful for gastrointestinal digestion. Drink water on an empty stomach, of course, at any time. Drinking when you are thirsty can only quench your thirst, but it won't help. The effective drinking method is to drink on an empty stomach, and the water will flow directly from the digestive tract and be absorbed by the body; Drinking water after meals is not as good as drinking water on an empty stomach. Give it a try! People who have the ability to leave work often ignore drinking water because of their work, or prefer not to drink water in order to avoid the suspicion of "borrowing urine". I especially advise you not to drink water on the grounds of "going to the toilet often". In this way, the bladder and kidneys will be damaged, which is easy to cause backache. As long as you get into the habit of drinking water, your bladder will get used to it, and the frequency of going to the toilet will naturally decrease. But it is normal to drink eight glasses of water every day and go to the toilet seven or eight times, which is a necessary substitute for metabolism. Remember that the way to drink water doesn't care about satisfying the thirst of throat and neck. It's no use taking a sip of water when you're dry. Water is as important to the body as oxygen. Drinking water is the only way to prolong life for the body; Drinking water to the body is the basic principle of brightening skin. For the sake of health, beauty and water, why not drink it? Drinking schedule AM6:30 After a whole night's sleep, the body began to lack water. Drinking 250CC of water before getting up can help detoxify the kidneys and liver. Don't eat breakfast right away, wait for half an hour for water to melt into every cell, and then eat it after metabolism! (Very important! Body sewage depends on it! At 8:30 in the morning, from getting up to the office, time is always tight, and the mood is also very tense, and the body will dehydrate invisibly, so when you get to the office, don't rush to make coffee, give yourself a glass of water of at least 250CC! AM 1 1:00 After working in an air-conditioned room for a period of time, you must give yourself the third glass of water in a day when you get up, which will help to relax your nervous working mood! PM 12:50 Half an hour after lunch, drinking some water instead of those artificial drinks that make you fat can strengthen your digestive function, which is not only beneficial to your health, but also helpful to keep fit. PM3:00 Replace afternoon tea and coffee with a cup of healthy mineral water. Drinking a large glass of water can not only replenish the water lost in the air-conditioned room, but also help to clear your head. PM5:30 Drink another glass of water before leaving the office after work. If you want to lose weight by drinking water, you can drink a few more cups to increase your satiety. After dinner, you won't overeat. PM 10:00 Drink another glass of water one to half an hour before going to bed, and the goal will be achieved! I have ingested 2000 ml of water today. But don't drink too much at a time, lest going to the toilet at night affect the quality of sleep. Remember: drinking salt water early and honey late in winter is dry, which often leads to excessive internal heat, constipation and indigestion. There is a saying in traditional Chinese medicine that "drink salt water early and honey late", which is especially suitable for this season. Traditional Chinese medicine believes that salt has the functions of clearing heat, cooling blood and detoxifying. According to Compendium of Materia Medica, salt can "harmonize viscera, eliminate lodging and make people strong". Therefore, drinking a cup of light salt water on an empty stomach after getting up in the morning is conducive to reducing fire and benefiting the kidney, keeping the stool unobstructed and improving the digestion and absorption function of the stomach. Honey has the functions of tonifying middle warmer, moistening dryness, relieving pain and detoxifying, and is often used to treat diseases such as spleen and stomach weakness, dyspepsia, lung dryness and dry cough, intestinal dryness and constipation. Modern medical research has proved that substances such as glucose, vitamins, phosphorus and calcium contained in honey can regulate nervous system dysfunction, thus increasing appetite and promoting sleep. Therefore, taking 10-20 ml of honey before going to bed every day and taking it with warm boiled water can not only strengthen the spleen and stomach, replenish qi and blood, but also calm the nerves and relieve boredom. But when drinking salt water and honey, we should also pay attention to it: salt contains a lot of sodium, which will lead to an increase in blood pressure. Therefore, the concentration of saline should be low, and the salt content in 100 ml water should not exceed 0.9 g. Patients with acute nephritis, liver cirrhosis, ascites and edema had better use boiled water instead, so as not to increase the burden on kidneys and hearts. Honey is not suitable for diabetics because of its high sugar content. In addition, salt water and honey must be drunk together, because they complement each other. The content of potassium in honey is high, which helps to excrete excess sodium in the body.
