To transform tap water into clean and healthy drinking water, the correct method of boiling water is extremely important. We often see mistakes like this in life: first, turning off the heat as soon as the water boils; second, letting the water boil for a long time; third, boiling the water for a few minutes with the lid on. In fact, this is not good for water safety and health. The correct method is: when the water is about to boil (80-90 degrees Celsius), open the lid, wait for the water to boil, then cook for 2-3 minutes, and then turn off the heat. If you cannot grasp the time when the water is about to boil every time, you can open the lid immediately when the water boils and then wait for another 2-3 minutes.

The reason for this is that there are more and more organic pollutants in water now. Some substances are volatile and will evaporate with water vapor when heated. Therefore, open the lid of the kettle when the water is about to boil, and boil the water for two or three minutes to maximize the volatilization of these substances. On the other hand, boiling water for too long will also cause the water to age and form harmful substances. Therefore, healthy water that meets human needs should be fresh.

In addition, if water is boiled and left for too long, it will turn into aged water, and the toxic substances in aged water will increase as the water is stored for longer. Therefore, it is best to drink the water you boil on the same day. Experiments have shown that drinking boiled water that has been naturally cooled and left for no more than 6 hours is the most beneficial to human health!
