Can you drink boiled water overnight the next day

Overnight boiled water is harmless to the human body when drunk the next day.

After the water is boiled, the bacteria can basically be destroyed, and in clean and tidy air, the growth of bacteria is very slow or even impossible to grow, so even if it is "overnight" cool and white, there is no need to worry about getting infected with bacteria.

Some people believe that exposure to the air for too long will lead to a great increase in the amount of nitrite in boiling water, and many people are horrified when they hear that the overnight cool white boil will contain nitrite, in fact, the amount of nitrite in the overnight cool white boil is very small, if it is a container with a lid, then there is no need to worry.

However, if it is drunk in Liangbaikai, the bacteria in the mouth will enter the Liangbaikai, and if it is left overnight, there is indeed a risk of bacterial growth. Therefore, the water that has been drunk cannot be drunk "overnight".

After getting up in the morning, drink a cup of cold and white, which is good for health. Many people like to dry a glass of boiling water the night before and drink it again the next morning. This is okay when the temperature is not high; For example, in summer, when the temperature exceeds 30 degrees Celsius, the air humidity is high, and the bacteria multiply quickly, the cold boiled water overnight will lose its biological activity, and it is very easy to be contaminated and cause diarrhea.

You can pour half a small cup of boiled water the night before, then cover the lid, and mix the boiling water with warm water the next morning.

In addition, the time of cooling and boiling should not be too long, and the boiling water boiled on the same day is best drunk on the same day. It is best not to drink it again if it is left cool for more than 3 days.

Overnight boiled water can be drunk the next day.

Overnight boiled water can be drunk the next day, after the water is boiled, the bacteria can be basically eliminated, in a clean and tidy environment, the growth of bacteria is very slow or even unable to grow, as long as the boiled water is stored in a sealed and clean container to avoid bacterial contamination, then overnight boiled water can also be drunk.

However, if you leave the boiling water in an open container overnight, you should not drink it, because the bacteria in the air can multiply in the water and cause contamination. Especially in summer, high temperature and humidity will cause bacteria to multiply, and if you drink it greatly, it may cause physical discomfort. In addition, if the time is cool, the pants should be too long, and do not drink it after more than 3 days.

Precautions for drinking water

1. Don't drink too hot water.

Many people like to drink boiled water very much, the kind of boiling water that has just been boiled is very hot, some friends think that drinking water like this is very refreshing, but drinking water like this for a long time is not good for our body.

2. Don't drink water from the water dispenser.

Many people will not often clean the water dispenser, the water dispenser has been used for a long time, there are still a lot of dirty things, at this time, if you drink thousands of boiling water for a long time, it is not good for the human body, clean the water dispenser frequently, avoid drinking thousands of boiling water for a long time.

3. Drink some water before eating.

It's best to drink some water before eating, because drinking water can occupy some gaps in our stomachs, and the food we consume will be less aggressive. Especially at dinner, drinking a glass of water can make us feel full, and eating less at night is healthier for us.

Overnight boiled water is drinkable the next day.

If you boil water at night, you can drink it the next morning (no more than 12 hours), but if it is cold after boiling, you should only drink it for 20 hours at most. The time of cold and white water should not be too long, and do not drink it again if it is placed for more than 3 days. Cover the lid when the water is cool, the indoor temperature is relatively low, and the bacteria produced after the overnight are generally less.

In general, it is okay to drink water overnight, but try to drink it the next day and avoid overnight again. In addition, there are requirements for the preservation of overnight water, and it is not recommended to drink it if it is placed in a cup, kettle, etc. without a lid or with a lot of limescale, or in a dusty and stuffy environment.

Difference Between Purified Water and Boiled Water:

1. Purified water, as the name suggests, is "pure" because it is manufactured by reverse osmosis, distillation, deionization or ion exchange and other processing methods in the specific treatment process. The most common tap water, that is, the Baikaishan high water that people drink, is to absorb rivers, lakes, groundwater and surface water through the water intake pumping station of the water plant, and remove the sediment and debris in the water through sedimentation, disinfection, filtration and other processes.

2. Although tap water and purified water are both drinking water, there is a clear difference in the quality standards of these two types of water stipulated by the state. For example, the content of cyanide in tap water in physical and chemical standards is required, while the requirements for pure water are required, and the difference between the two requirements is 25 times; The total number of colonies in the hygiene index is 100 ml for tap water and 20 ml for purified water, which is 5 times different.

3. At present, pure water is filled in special barrels and transported in a sealed form. If the special barrel is cleaned and disinfected after **, strict specifications are carried out. The tap water is delivered through pipelines, one is directly to the end user, and the other is through the high-rise water tank, reservoir and then to the end user's home.
