The boiled water must drink on the day

There are many types of citation water on the market today, but whether it is past, present or future, tap water is still the main daily drinking water for everyone.

In terms of nutrients, tap water minerals, although not rich in mineral water, do not reach a pH of 7-8, but it can still meet the needs of the human body. The most important thing to pay attention to tap water is its pollution problem.

How to turn tap water into clean and healthy drinking water? The correct method of boiling water is very important.

In daily life, we often mistakenly boil water. First, the water just boils and immediately shuts off the heat. Second, water boils and lets it boil for a long time. Third, the water is boiled and then covered with a lid for several minutes. In fact, this is not good for the safety and health of water. The correct approach is: When the water is boiled (about 80-90 degrees Celsius), open the lid, wait for the water to open for 2-3 minutes, and then extinguish it. If you can't always grasp the time when the water is going to boil, open the lid as soon as the water boils, and wait another 2-3 minutes. The reason for this is that now there are more and more organic pollutants in the water, and some substances are volatile, and they will volatilize with steam when heated. Therefore, when the water is boiled, the lid of the kettle should be opened, and after the water is opened for two or three minutes, these substances can be volatilized to the maximum. On the other hand, if water is boiled for too long, it can also cause water aging and the formation of harmful substances. Therefore, water that meets human needs should be fresh.

In addition, if the water is left for a long time after being boiled, it will turn into aged water, and the toxic substances in the aged water will increase as the water storage time increases. Therefore, it is advisable to drink water that day and drink it on the same day. Experiments have shown that drinking boiled water that has been naturally cooled and allowed to stand for no more than 6 hours is most beneficial to human health.
