Drinking water knowledge
People are made of water, and drinking more water has naturally become a key part of health care.
 "Do you drink water?" - This is something you do every day, but you may not be doing it right.  According to Zhao Feihong, director of the Health and Drinking Professional Committee of the Beijing Protection and Health Association, the “water blindness”, which is incorrect in drinking habits and methods, accounts for a large proportion of modern people, and there are many misunderstandings.
 Myth 1: The safest to drink boiled water
 Many people have the habit of drinking boiled water. They feel that it is safer to drink water, but getting used to it is not the same as health.  If the water body is contaminated, there are still various toxic substances left in the boiled water, which affects the health of our drinking water.
 Boiled water, safe water, boiled water, still residual compounds
 Experiments have shown that there are still various water, heavy metals such as chloride, arsenide and nitrite in boiling water, substances such as chloroform, carbon tetrachloride, pesticides, pesticide residues and other harmful organic substances in water, many of which cannot  Use boil to remove.
 Boiled water, healthy water, may contain carcinogen trihalomethane
 The purification and sterilization process of tap water is mainly done by applying chlorine gas. In fact, chlorine gas itself is a toxic substance, which can kill bacteria, but it can endanger health if it exceeds the standard.  During boiling water, chlorine can also chemically react with organic matter in tap water to form an organic compound, trihalomethane (disinfection by-product), which is recognized as a carcinogen in the world.
 Myth 2: Drinking bottled water is convenient and safe
 Drinking bottled water requires buying water, waiting for water, and drowning, which is very inconvenient.  In the process of circulation, it is easy to be secondary pollution. After the bottled water is opened, the shelf life is up to 7 days. Under certain suitable temperature and environmental conditions, the bacteria may re-grow. After 7 days, the bottled water may basically become  The stagnant water of new pollutants is not suitable for drinking.  If the barrel is not clean or the plastic of the bucket is inferior recycled plastic, it directly causes secondary pollution of the bottled water.

 Suggestion: Buy a regular brand and finish it as soon as possible within three days.

 Myth 3: Pure water is clean and safe water

 The World Health Organization's collection of papers, "Nutrition in Water," clearly states that no matter how rich the diet is, the body always needs to take a certain proportion of mineral elements from the water. Drinking pure water that filters out nutrients for a long time will cause more  The great health hazard causes the human body to ingest only a small amount or not to take calcium and magnesium, directly affecting the intestinal mucosa, metabolism and mineral dynamic balance or other human functions, increasing the possibility of toxic metals in the diet, etc.  .
 Recommendation: Do not drink for a long time.
 Myth 4: Drinking ice water on a hot day is more thirsty
 Many people like to get up in the morning to drink a glass of ice water. In fact, this is very unscientific.  Drinking ice water can easily cause gastric mucosal vasoconstriction, affect digestion, stimulate the gastrointestinal tract, accelerate the gastrointestinal motility, and even cause intestinal cramps, leading to abdominal pain and diarrhea.  Normal people drink ice water, especially sweet drinks, which can cause stomach problems after drinking on an empty stomach.
 Recommendation: drink normal temperature water (25 ° ~ 40 °)
 Myth 5: Drinks can also replenish water and drink well.
 "White water has no taste, or drink it, it can also hydrate." Many people, especially children, don't leave their hands with cola and fruity drinks every day. Drinking water with drinks is tantamount to spending money to buy a sick person.  "Not only does it not help the body to replenish water, but it also reduces appetite and affects digestion and absorption." Zhao Feihong said.  Moreover, most of the carbonated beverages contain citric acid, which accelerates the excretion of calcium during metabolism and lowers the calcium content in the blood. Long-term drinking can lead to calcium deficiency.
 Drinking water is worse than drinking more water.
 A cup of warm water in the morning, detoxification
 After one night of metabolism, a cup of warm water in the morning can lubricate the intestines, accelerate metabolism, and allow the body to be discharged from the body. 
 Drink plenty of water when you have a cold, increase your resistance
 When you have a cold and a fever, there will be accelerated metabolism such as sweating and shortness of breath. At this time, you need to add a lot of water.  Li Baihua emphasized that drinking more water not only promotes sweat discharge and urination, but also helps regulate body temperature and increase the body's resistance.
 Drink plenty of water when constipation, promote bowel movements
 Chinese medicine believes that constipation has many reasons, one of which is caused by "jin dry intestines dryness."  This kind of constipation is caused by the lack of body in the human body. Drinking water with a large mouth can quickly supplement the body fluid, thereby stimulating bowel movements and promoting bowel movements.
 Drinking water at high frequency when irritating, alleviating emotions
 According to experts, people sometimes have an annoyed and boring state. The performance is that the palms and feet have different degrees of scalding. It is a manifestation of yin deficiency, internal heat and fire.  This kind of irritability tends to lead to loss of body and lack of fluid in the body, so increasing the frequency of drinking water can effectively alleviate irritability. 
 Drink some light salt water after diarrhea, add strength
 People often have vomiting and diarrhea due to improper diet or unhygienic conditions. In order to avoid dehydration caused by severe vomiting or diarrhea, you can drink some light salt water to replenish your body and relieve the weak state.
