How to drink water is healthy? Three glasses of water a day to ensure health.

Drinking water is one of the means to ensure human life, and drinking clean water and healthy water is the way to ensure health. Modern people have high work pressure and fast pace of life, and drinking water will become more time-saving subconsciously. So there are bottled water and bottled water on the market. However, experts say that whether it is bottled water, bottled water or boiled water at home, we need to pay attention to many things to ensure health. So, how to drink water is healthy? How to drink water: three glasses of water a day to ensure health. First cup: a glass of water in the morning. After a night of metabolism, the garbage in the human body needs external force to be discharged, and water is the best "cleaner". Many friends never drink water in the morning, but they start drinking water under the influence of others, but after a week, they have a stomachache after drinking water. In fact, this is because he didn't drink the right water. He drinks cold boiled water. In fact, too cold water will hurt the spleen and stomach, so he should drink warm water in the morning, and the temperature is about 40 degrees Celsius. The second cup: Be sure to drink water when it is salty. People in China like to eat pickles, but if they eat too salty and don't drink water, they will suffer from high blood pressure and even cancer. Before the refrigerator was invented, residents in Hokkaido, Japan had the habit of eating salted fish, eating more than 30 grams of salt a day. As a result, Hokkaido has become a "kingdom of gastric cancer". The third cup: drink a glass of water before going to bed at night. Many elderly people worry that drinking water before going to bed will cause them to get up frequently at night. Young women are afraid that their eyes will swell the next day if they drink water before going to bed. Young men have a rough life and don't deliberately drink water at night. In fact, this glass of water is also very important at night. When people are asleep, the internal organs continue to work, which will cause water loss and high blood viscosity. Therefore, drinking some water before going to bed can reduce blood viscosity and reduce the risk of cerebral thrombosis. For the elderly, in the dry autumn and winter seasons, water can also moisten the respiratory tract and help people fall asleep better. How to drink water: ten bad habits of drinking water: the water dispenser never washes. Barreled water and drinking fountains are very common in families, offices and public places. Have you ever thought that the used water dispenser has never been "bathed" since it was put there? Drinking fountains seem to let people drink high-quality water, but in fact, "secondary pollution" is very serious. Whenever you turn on the tap of the water dispenser, you hear the sound of "grunting" and a string of bubbles are dug out of the bucket. This means that when air enters, dust and microorganisms will be brought in. According to the test data of the national environmental health monitoring department, if the cold and hot water containers of barreled drinking fountains are not cleaned for 3 months, a large number of bacteria such as Escherichia coli and Staphylococcus will multiply. So it's best to clean it once a month and once every two weeks in summer. The drinking fountains in the office need to be cleaned frequently because of frequent use. Bad habit 2: drink as soon as the tap water is turned on. It is a good habit for people in China to drink boiled water, but do you know? You can't drink water once it is boiled. Because our tap water is chlorinated and disinfected, the combination of chlorine and residual organic matter in water will produce carcinogenic compounds such as halogenated hydrocarbons and chloroform. Jiang Weibo, a professor at the College of Food Science and Nutritional Engineering of China Agricultural University, suggested that there should be three steps when boiling water: first, take out the tap water and let it burn for a while; Open the lid when the water is about to boil; Finally, turn off the fire 3 minutes after the water boils, so that the chlorine content in the water can be reduced to the safe drinking standard, which is the real "boiling water". Bad habit 3: Love to drink bottled water. Convenient to carry and drink. In China, the consumption of bottled water is increasing by 30% every year. Dong Jinshi, executive vice president of the International Food Packaging Association, pointed out that polyester bottles used in bottled water often contain substances that may cause chronic poisoning, especially when the bottles are in a high temperature environment or are not drunk in time after opening, harmful substances will penetrate into the water and endanger health. Therefore, bottled water must not be heated or exposed to the sun. "Many people like to put a box of water in the car, which is wrong. Especially in summer, the temperature of the trunk is very high, which makes it easy for harmful substances to enter the water. " Dong Jinshi suggested that the best way is to buy a good quality kettle to bring your own water, which is safe and environmentally friendly. Bad habit 4: Drink thousands of boiled water. "There are more and more families using electric kettles now. Many people can't finish drinking water at once, and then boil it repeatedly. This kind of boiled water is best not to drink. " Zhao said that after the water is boiled, try to drink it as soon as possible, and don't heat it repeatedly. Many people are worried about whether the water in the drinking fountain is boiling water. Due to the limitation of materials, the highest temperature of water in drinking fountains is generally around 90 degrees Celsius, not boiled water. "But the best drinking time of bottled water is 1- 15 days after leaving the factory. Once it exceeds 15 days, there are too many bacteria in the water to drink. " Bad habit five: don't be thirsty or drink water. According to a survey in China, 70% of adults only drink water when they feel thirsty. But when you feel thirsty, your body loses at least 1% water. Drinking water is not to quench thirst, but to let it participate in metabolism and be absorbed by the human body. Long-term water shortage will increase the viscosity of blood and induce cardiovascular and cerebrovascular diseases. At the same time, the less you pay attention to drinking water, the lower your desire to drink water, and people will become more and more "dry". Therefore, whether you are thirsty or not, you should replenish water in time. Take a bottle of water when you go out and take a sip at any time; Put more water cups in the office or at home and drink them whenever you have the chance. Bad habit 6: Don't drink enough glasses of water every day. People who go to work often ignore drinking water because of their work. In this way, their bladders and kidneys will be damaged. The Dietary Guide for China Residents suggests that adults who live in a mild climate and have less physical activity should drink at least 120 0 ml of water every day, about 6 cups. If you exercise a lot and sweat a lot, you should increase the amount of water and replenish water in time. Some people may ask, it has always been said that drinking no less than 2000 ml of water every day, that is, 8 glasses of water. Why is there only 1200 ml now? In fact, 2000 ml refers to the total amount of water that people need in a day. Fruits and vegetables contain a lot of water, even in staple food and meat. A large part of the water people need comes from food. Six cups is the least, and some people need to drink more. For example, irritable people can relax by drinking more water, while obese people can keep their weight by drinking more water, and they should also replenish water in time after exercise and bathing. Bad habit seven: don't drink water according to your constitution, drink instead of water. "Boiling water is tasteless, let's drink it." Many children keep cola and fruity drinks every day. Replacing water with drinks is tantamount to spending money to treat diseases. "Not only can it not replenish water to the body, but it will also reduce appetite and affect digestion and absorption." Zhao said to him. If you must drink tasty water, you should improve it according to your own physique. For example, people with constipation can drink honey water or fruit and vegetable juice, which can promote intestinal peristalsis; People with a cold stomach should drink less cold green tea, herbal tea and juice, and drink more warm black tea and ginger juice. Bad habit 8: Don't drink water in the morning, and regret it when you are old. The first glass of water in the morning is really life-saving water, and middle-aged and elderly people should pay more attention. After a night of metabolism, the garbage in the body needs to be cleaned. Drinking a glass of water can reduce blood viscosity and increase circulating blood volume. It is best to choose the following three kinds of glasses of water in the morning: the first one is clean water, boiled water and mineral water, which can reduce the viscosity of human blood; The second is lemonade. Citric acid can stimulate appetite in the morning. The third is light salt water, which is very good for people with constipation. Bad habit 9: Don't replenish water immediately when you are salty. Eating too salty will lead to high blood pressure, decreased saliva secretion and edema of oral mucosa. If you eat salty, the first thing to do is to drink more water, preferably pure water and lemonade, and try not to drink sugary drinks and yogurt, because too much sugar will also aggravate the feeling of thirst. Light soybean milk is also a good choice, more than 90% of it is water, and it also contains more potassium, which can promote the discharge of sodium and taste sweet. Bad habit 10: Don't drink water before going to bed. It is not advisable to drink too much water before going to bed, but you can drink a little, especially for the elderly. When people sleep, due to the loss of water in the body, the water in the blood decreases and the blood viscosity becomes higher. Drinking some water properly before going to bed can reduce blood viscosity, thus reducing the risk of cerebral thrombosis. In addition, in dry autumn and winter, water can also moisten the respiratory tract and help people fall asleep better.
