Li Renaissance, director of the Beijing institute of public health drinking water: health news

      Drinking water is so varied that many consumers have no choice, they don't know what to drink, and they don't know how to drink water. Here are the questions that should be noted when drinking water and mineral water, and a healthy drinking method.

      When the tap water is not used for a long time, you should turn on the faucet and let the water flow for 2 to 3 minutes, then take fresh water for drinking water. Put the tap water in a water container for 1~2 hours, then boil water after natural purification and clarification. But water cannot be placed too long, because after a long time water cluster aggregation can be gathered into each other macromolecules regiment, minerals can also precipitate, oxygen out, thus lost the "young" and become a recession, aging, loss of vitality. "A thousand boiling water" means a lot of boiling water, the water in the water fountain is often in the state of repeated boiling. So try not to drink as much water as possible, because as the number of boiling increases, some harmful substances in the water will also increase. In addition, after boiling water, you should open the lid for 2~3 minutes, and remove the volatile harmful substances from the tap water.

      Mineral water with some high-mineralized mineral water is rich in calcium carbonate and magnesium carbonate. The calcium carbonate and magnesium carbonate in the water will form white sediment and affect the taste. Calcium carbonate and magnesium carbonate form water scale in heated containers such as water dispenser, which can affect the heat exchange of water dispenser, resulting in the increase of energy consumption. Therefore, use water fountain to heat mineral water to clean water dispenser in time, remove scale. Some mineral water of high salinity are rich in iron, calcium, magnesium, zinc and other trace elements and metal ions, if taking with mineral water, mineral water of some metal elements is easy to react with the ingredients in drug, affect the efficacy. Mineral water of high mineralization should not be heated, and mineral water of medium mineralization can be heated and drinkable. When mineral water is transported and stored, avoid direct sunlight and put it in a cool place. The mineral water should be drunk as soon as possible after opening, not more than 24 hours, otherwise it is easy to cause bacterial contamination. Water that is not consumed can be heated and then consumed. Moreover, if there is impurity in the mineral water bottle, it does not mean that the water is not clean, and the impurities in the water need to be treated differently. Natural mineral water is rich in many kinds of mineral elements, minerals may occur after a long period.this exhalation deposition, form white particulate matter in the water, does not affect the quality of mineral water, will not endanger human body health.
