“Do you drink water?” –something you do every day, but you may not do it right. Is the water you drink safe or not? What kind of water should you drink for your body type? Have you ignored the three “life-saving waters”? In the view of Zhao Feihong, director of the Beijing Health Protection Association Health Drinking Professional Committee, drinking habits and incorrect way of “water illiteracy”, in modern people occupy a large proportion. “Don’t look at drinking water is a small thing, drinking incorrectly can also bring big trouble.” Drinking water is not safe Water looks clear and clean, but there are microorganisms, harmful substances hiding, whether drinking barrels of water, bottled water or their own boiled water, we should try to avoid the following four bad habits. Bad habit one: the water dispenser never wash. Barrels of water and water fountains whether in the home or office, public places have been very common, you have not thought, with the water fountain since it was put there never “bathed”. Drinking fountains seem to let people drink good quality water, but the reality is that “secondary pollution” is very serious. Whenever you open the water fountain faucet, hear the sound of “grunt”, the barrel turned out a series of bubbles, which is the air into the dust and microorganisms will be brought in. According to the national environmental health monitoring department test data show that the hot and cold water tank inside the water dispenser 3 months without washing will multiply bacteria, such as E. coli, staphylococcus, etc.. Therefore, it is best to clean once a month, once every two weeks in summer. Office drinking fountains because of the frequent use, more must be diligent cleaning. Bad habit two: tap water a boil to drink. National people drink plain water is a good habit, but you know what? Water can not be boiled to drink. Because our tap water are chlorinated and disinfected, where chlorine combined with the residual organic matter in the water, will produce halogenated hydrocarbons, chloroform and other carcinogenic compounds. Professor Jiang Microwave, School of Food Science and Nutritional Engineering, China Agricultural University, suggested that when boiling water, it may be worth taking three steps: first of all, tap water will be picked up and placed for a while before boiling; water is almost open when the pot lid open; finally, the water is boiling and then turn off the fire for 3 minutes, so that the chlorine content of the water down to safe drinking standards, is the real “boiling water”. Bad habit three: love to drink bottled water. Easy to carry, open the lid can drink, in China, bottled water consumption is increasing at an annual rate of 30 percent. International Food Packaging Association executive vice president Dong Jinshi pointed out that the polyester bottles used in bottled water often contain substances that may lead to chronic poisoning of humans, especially when the bottle in a high-temperature environment, or open in time to drink, harmful substances will seep into the water, endangering health. Therefore, bottled water must not be subjected to heat or exposure to the sun. “Many people like to put a box of water in the car, which is not right. Especially in summer, the trunk temperature is very high, easy to let harmful substances into the water.” Dong Jinshi suggested that the best way is to buy a good quality water bottle with their own water, safe and environmentally friendly. Bad habit four: drink a thousand rolls of water. “Now more and more families with electric kettles, many people burned water once to drink, after a while and repeatedly boil. This rolling water is best not to drink.” Zhao Feihong said, the water boiled as much as possible when the drink is finished, do not repeatedly heated. Many people are concerned about the water in the water fountain is not a thousand rolling water, because of material restrictions, the highest temperature of water in the water fountain is generally about ninety degrees Celsius, not up to the boiling state, not a thousand rolling water. “But the best time to drink barrel water is 1-15 days after the factory, once more than 15 days, too much bacteria in the water, it is not appropriate to drink again.” Bad habit five: not thirsty do not drink water. A domestic survey data show that 70% of people are found thirsty before drinking water. Do not know when you feel thirsty, your body has lost at least 1% of the water. Drinking water is not to quench thirst, but to allow its participation in metabolism, absorbed by the body, prolonged water shortage will increase the viscosity of blood, inducing cardiovascular disease. At the same time, the less attention to drinking water, the lower the desire to drink water, people will become more and more “arid”. Therefore, whether thirsty or not, you should be timely hydration. When you go out with a bottle of water in your hand, drink a sip at any time; office or home to put on a few more water cups, stitching, have the opportunity to drink. Bad habit six: not enough to drink 6 glasses of water a day. Working people often neglect to drink water because of work, and in the long run, the bladder and kidneys will be damaged. The Dietary Guidelines for Chinese Residents recommends that adults living in mild climates and light physical activity should drink at least 1200 ml of water a day, about 6 cups of water. If there is a lot of activity and sweating, increase the amount of water you drink accordingly and rehydrate in a timely manner. Some people may ask, before has been said to drink not less than 2000 ml of water a day that is, 8 glasses of water, why now only 1200 ml? In fact, 2,000 ml is the total amount of water people need a day, fruits and vegetables contain a lot of water, even staple foods, meat, the body needs water, a large part from the food. 6 cups is the minimum amount, some people need to drink more. For example, irritable people drink more water to soothe the mood, obese people drink more water to maintain weight, after exercise, after bathing are also timely hydration. Bad habit seven: not according to the body to drink water, drinks instead of water. “Plain water is tasteless, or drink it.” Many children every day cola, fruit-flavored drinks do not leave their hands, with drinks instead of water, is like spending money to buy body disease. “Not only does not play a role in hydrating the body, but also reduces appetite, affecting digestion and absorption.” Zhao Feihong said. If you must drink flavored water, but also according to their own constitution, appropriate improvements. For example, constipated people can drink some honey water or fruit and vegetable juice, can promote intestinal peristalsis; and people with cold stomach to drink less cold green tea, herbal tea, juice, drink more warming black tea, ginger water. Three cups of “life-saving water” life-saving water, not really drink it to save lives, but this way of drinking water will bring great health benefits, adhere to drink the effect of prolonging life. Bad habit eight: not drink water in the morning, to old age are regretted. The first glass of water in the morning is the real sense of life-saving water, the elderly should pay more attention. After a night of metabolism, all the body’s waste needs to be scrubbed. Drinking a glass of water can reduce blood viscosity and increase circulating blood volume. The morning cup of water is best to choose the following three: the first is clear water, plain water, mineral water can be, can reduce the human blood viscosity; the second is lemon water, citric acid can enhance the morning appetite; the third is light salt water, it is very beneficial to people with constipation. Bad habit nine: eat salty not immediately hydrate. Eating too salty can lead to high blood pressure, but also can lead to reduced saliva production, oral mucosa edema, etc.. If you eat salty, the first thing to do is to drink more water, preferably plain water and lemonade, try not to drink sugary drinks and yogurt, because excess sugar will also aggravate the feeling of thirst. Light soy milk is also a good choice, of which more than 90% are water, and also contains more potassium, can promote the discharge of sodium, and the taste is relatively sweet. Bad habit ten: not drinking water before bed. Should not drink too much water before bed, but you can slightly sip on two, especially the elderly. When people are asleep, due to the loss of water in the body, resulting in less water in the blood, blood viscosity will become higher. Drinking water before going to bed can reduce blood viscosity, thus reducing the risk of cerebral thrombosis. In addition, in the dry autumn and winter season, water can also moisten the respiratory tract, helping people to sleep better.
