What type of water cannot be drunk?

Reference: (1) Boiling water and steaming water are harmful to the body. “Thousand-boil water” is water that has been boiled on the stove for a long time, as well as water that has been boiled repeatedly. in an electric water heater while drinking tea. Because "thousand boiling water" has been boiled for too long, the non-volatile substances contained in the water, such as calcium, magnesium and other metal components, and the nitrite content are very high. Drinking “thousand boiling water” for a long time will do it. interfere with people's gastrointestinal function and cause temporary diarrhea and increased abdominal pain. Toxic nitrites can also cause hypoxia in the body, which can lead to coma or even death in severe cases. In addition, after repeated boiling of water, minerals easily absorbed bythe human body turn into precipitated particles that are difficult to be absorbed by the human body, thereby losing the nutritional value of water. (2) Aged water cannot be drunk. The longer the storage period of aged water and stagnant water, the more toxic it will be. It will significantly reduce the metabolism of minor cells and affect growth and development. It accelerates the aging of middle-aged and elderly people and increases the incidence of cancer. (3) Do not drink water that is too hard. Water hardness refers to the content of dissolved minerals in the water. The higher the content of calcium, magnesium and other minerals in the water, the harder the water. Drinking high-quality drinking water will affect the digestion and absorption functions of the gastrointestinal tract and cause indigestion or diarrhea. Long-term alcohol consumption can increase the incidence of stones in internal organs. (4) Themedical water cannot be used as drinking water. There are currently drinking water on the market called “electrolyzed water” and “oxygen-enriched water”. Strictly speaking, it is medical water and cannot be used as normal drinking water. people and are not suitable for daily consumption of large quantities of water. (5) It is not recommended to drink distilled water. Distilled water is soft water with too few or no minerals. (6) Drinking purified water is not recommended. Experts believe that the biggest disadvantage of purified water is that it removes calcium, magnesium, fluoride, iodine, selenium and other minerals and trace elements necessary for the human body. Some data show that calcium and magnesium intake in drinking water accounts for 5-20% of total intake. Lack of this part of intake can affect the normal growth of adolescents. Purified water hashas strong ability to dissolve various trace elements, compounds and nutrients. After drinking a large amount, some substances necessary for the human body will be quickly dissolved in water and excreted out of the body. the elements of the human body will lose balance, and long-term drinking may cause illness. So far, scientists have recognized that 15 trace elements are necessary for the human body, and some of them are present in water, such as selenium which plays an important role in the functioning of the heart and liver. (7) Purified water is acidic water. The biggest problem with purified water is not that it doesn't contain minerals, but that it has an acidic pH. Once a person's constitution becomes acidic, cell function will deteriorate, and the functions of various organs and tissues in the body will also weaken; metabolism will slow down and waste will not be easily removed, the charge on the kidneys and liver will increase; leading to the formation of chronic diseases. Purified water mainly refers to distilled water and space water. During the production process, on the one hand, germs, organic matter and some toxic elements harmful to the human body are removed, on the other hand, trace elements and minerals beneficial to the human body are also removed; Long-term alcohol consumption can lead to malnutrition, decreased immunity, and symptoms such as general weakness, collapse, syncope, and muscle tremors. Pure water cannot penetrate the cell membrane. According to NMR measurements, the half-width of water molecule clusters of distilled water and purified water is much larger than that of high-quality mineral water. However, this type of water cannot directly enter cells through the cell membrane, and weWe cannot expect this type of water to carry the nutrients needed by the human body into the cells. Therefore, drinking pure water for a long time will affect the absorption, utilization and deposition of nutrients in the body and accelerate the loss of nutrients. (8) Raw water that cannot be drunk. River water, stream water, well water, reservoir water and tap water contain a variety of bacteria, microorganisms and zoonotic parasites that are harmful to the human body. Drinking this raw water can easily cause acute gastroenteritis, viral hepatitis, typhoid, dysentery and parasitic infections. (9) Repeatedly heating bottled water can cause cancer. (10) Beverages are not equal to drinking water, as water can cause chronic benzene poisoning. (11) Antimony present in bottled mineral water may be harmful to health. continue toe dissolve in mineral water. The chemical element “antimony” is a toxin that is potentially fatal to human health in the long term. Very small amounts of antimony will not make you sick, but large amounts can cause severe vomiting or even death. (12) Health Killer Faucets. Tap water in nearby faucets and water pipes that have been out of service overnight is stagnant and residual microorganisms in the water are multiplying in large numbers. Therefore, it is not suitable for consumption, brushing teeth or gargling. You can pour about a basin of water first before using it.

Bottled water is 18.9 liters.

Large water buckets are usually 18.9 liters and are placed above the water dispenser. At present, almost all bottled water in the domestic market is packaged in 5-gallon bottles, which corresponds tond to standard 18.9 liter bottled water. Bottled water should be consumed within 5 days. The storage time is too long, which can easily cause water pollution. Indeed, water, air and the appropriate temperature in the water dispenser provide favorable conditions for the reproduction of Escherichia coli, Pseudomonas aeruginosa, mold, etc. Over time, this will seriously affect the quality of drinking water.
