Water boiler manufacturer Honghua Electric will explain to you whether overnight water is drinkable or not.

There has always been a saying that overnight water cannot be drunk. The reason is that overnight water can cause diarrhea and even cancer, which makes many people afraid. Experts say that whether you can drink water that has been left overnight depends on the time and environment in which it is left. It has little to do with whether it is left overnight. As for the claim that it causes cancer, it is even more groundless. According to popular sayings, the main reason why you cannot drink overnight water is that overnight water can cause diarrhea and even produce carcinogens. In this regard, Sun Guiju, director of the Department of Nutrition and Food Hygiene at the School of Public Health of Southeast University, explained that both overnight water and fresh water contain these substances, and these substances will not cause diarrhea. Diarrhea may occur because the water was exposed to the air with the lid open and contaminated by bacteria during the storage process. It has nothing to do with whether it was left overnight.
As for the claim that overnight water causes cancer, Fan Zhihong, associate professor at the Department of Nutrition and Food Safety of China Agricultural University, pointed out that this is even more impossible. Take ordinary drinking mineral water or purified water as an example. There are either only minerals and trace elements in the water, or nothing at all.
The so-called overnight water is not a scientific concept at all. If it is left overnight, there will be more bacteria, but if it is not left overnight, there will be fewer bacteria? Fan Zhihong pointed out that whether the water is drinkable has little to do with whether it has been left overnight. It mainly depends on the storage time and storage environment of the water. As long as the water is boiled and stored with the lid closed, the water quality will not be bad.
If you are worried about being exposed to the air for a long time and being contaminated by bacteria, you only need to boil the water again to achieve the purpose of sterilization. If you want to drink cold water in the morning, you can choose to boil the water before going to bed, and then cover it with a well-sealed lid to cool it. This will not only prevent foreign objects from falling into the water, but also prevent the drinking water from being contaminated by bacteria in the air.
