How to drink bottled water healthily? What's the difference between different water species?

Barreled water is also facing a very common "secondary pollution" problem. Climate, environment and personnel quality are the key factors leading to "secondary pollution" in the process of water conveyance. But excluding these factors, bottled water is much safer than tap water and community self-service drinking fountains. Barreled water refers to pure water or mineral water treated by modern industrial technology (reverse osmosis, electrodialysis, distillation, resin softening, etc.). ) and filled into PVC barrels through the filling production line. It is divided into pure water, mineral water and mineral water (minerals from pure water are artificially added). Many people will get used to repeatedly heating bottled water. Experts pointed out that this practice is not desirable, because repeatedly heated water will produce concentrated solutions of harmful substances such as heavy metals and arsenic compounds. In addition, the water dispenser should be cleaned regularly. Although it is not necessary to clean the barrel thoroughly every time, cleaning once a month is the embodiment of good hygiene habits. It should be noted that the detergent for cleaning the water dispenser is a chemical substance after all, and it must be rinsed before drinking. In addition, bottled water should be drunk within 10 days. The most common varieties of bottled water are pure water, mineral water and distilled water. Generally speaking, pure water is tap water that can be directly drunk, mineral water is natural mineral water containing certain minerals and trace elements, and distilled water is drinking water obtained by high-temperature distillation. When drinking the above bottled water, we need to pay attention to related problems: pure water does not contain any trace elements, and even life ions that nourish the human body do not exist. The more you drink, the more sour your body fluids will become, which may lead to the decline of human immunity and the possibility of disease. Distilled water, like pure water, is not suitable as a single drinking water because many minerals beneficial to human body have been removed. Bottled water is not suitable for direct drinking. Food will go bad if it is kept for a long time, and water will go bad if it is kept for a long time. So people are usually used to eating fresh food and drinking fresh water, but bottled water is not suitable for drinking when it is fresh. The bottled water sold in the market, whether it is distilled water, reverse osmosis water, mineral water or other pure water, has been filtered and disinfected many times in the production process, but the final disinfection before filling usually uses ozone, so the bottled water just filled contains high concentration of ozone. Although ozone has a strong disinfection effect, its strong oxidation is very harmful to human health. When ozone is inhaled into the body, it will destroy vitamin E in the skin, causing wrinkles and dark spots on the skin. In severe cases, it will also destroy the immune function of the human body and induce lymphocyte diseases. So if you drink bottled water when it is "fresh", you will undoubtedly take poison with you. The best way is to leave fresh bottled water for 1-2 days, and then drink it after the ozone dissipates. In addition, bottled water is not healthy water that can be safely drunk, especially bottled water that is used with drinking fountains. Faucets, water inlets and sewage outlets can easily let microorganisms and floating layers in the air enter the bucket, which will cause secondary pollution to the water in the bucket. In order to prevent drinking water that is polluted twice, the best way is to heat the water before drinking it. In order to prevent the repeated heating of water from producing a large amount of nitrite harmful to human body, citizens try to buy a water boiling machine when purchasing a water dispenser. This kind of drinking machine is controlled by microcomputer, which separates cold water from hot water, keeps the water temperature accurate and stable, and makes the drinking water clean and hygienic.
