Why is the overnight water? Can t drink it? Why can t you drink water overnight

In summer, when the temperature exceeds 30 degrees Celsius and the air humidity is high, bacteria multiply quickly, and the cold boiled water overnight will lose its biological activity, and it is very easy to be contaminated and cause diarrhea. The time of cold boil 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.

Many people think that boiled water can be drunk no matter how long it is left, and everyone is reminded that boiled water should not be drunk after more than three days. Once the water is stored for too long, it will be infected by bacteria to produce nitrite, once nitrite enters the human body in large quantities, it can make the tissues hypoxic, nausea, vomiting, headache, palpitation and other symptoms, and in serious cases, it can also make people die of hypoxia.

Many people think that overnight water cannot be drunk, and many people think that it can be drunk, but can it be drunk or not?

First of all, the bacteria in boiled water are basically inactive, so if the overnight water can remain pure during the overnight period, then it is completely drinkable, and this will not have any negative impact on our body.

Can't you drink water overnight? In fact, it can be drunk, because there will not be a large amount of nitrite in the water, and it is still far from exceeding the standard, so it is drinkable.

In general, overnight water can be drunk, but it depends on the situation. If the overnight water is kept in a clean container, it is not contaminated, there is no odor and discoloration, then it can be continued to drink. However, if the overnight water is kept in an unclean container or is contaminated, then it is not recommended to drink it.

In addition, the number of microorganisms and bacteria in the overnight water will gradually increase, and if it is stored for a long time, it may cause problems such as poor water quality, odor and discoloration, and even diarrhea. Therefore, it is advisable not to keep water for a long time, and it is better to drink fresh water every day.

In short, overnight water can be drunk, but pay attention to the preservation environment and storage time to ensure water quality safety and health.

There are two main reasons why water cannot be drunk overnight.

First, overnight water can be contaminated with airborne bacteria and microorganisms. Because the water contains nutrients and the temperature is suitable for microorganisms to multiply, it is easy to breed various bacteria, microorganisms and other potentially harmful substances during storage. If you drink the water overnight again, it may cause health problems such as gastrointestinal upset.

Second, water may lose its freshness after being stored for a long time, taste bad, and may even form an off-flavor. This is because when water comes into contact with air, it absorbs gases such as oxygen and carbon dioxide in it, resulting in qualitative change. In addition, there are some special conditions, such as if the shirt is placed in a plastic container for a long time, it may release environmental hormone compounds, which may have adverse effects on the human body after consumption.

Therefore, it is advisable to drink as fresh and clean water as possible every day and avoid overnight and reuse. Consumers can properly prepare several clean water cups or kettles to ensure that the water is fresh every time it is used.

Why can't you drink water overnight, as long as it is not polluted, drink it correctly.

There is a theory that overnight water will increase the nitrite content in the water, and the nitrite in it, which is a carcinogen, may cause cancer if consumed for a long time.

However, the generation of nitrosamines is not so easy, it needs to have certain precursor substances and environmental conditions, the most easy to produce nitrosamines is the gastric juice of humans and animals, and most of the gastric juice acidity is not enough, in order to generate nitrosamines, this phenomenon is also called endogenous nitrosation.

Because in people's minds, overnight water is similar to water that has been left in the air for a long time, and the water will increase the reproduction of many bacteria, which is not conducive to human health after drinking.

Why can't you drink water overnightDo you think you can drink water overnight? I don't know if I can do it quickly? Some people may feel strange, feel that they should not have thought much about this problem, some people want to know why the overnight water can not be drunk, because they are not very familiar, they dare not drink overnight water, after all, Chang Chang does not know much, and I don't know why I can't drink it, it is more troublesome, so I usually don't drink much Yanxun, so why can't I drink overnight water?

Why can't you drink water overnight1.Overnight water can harbor bacteria.

Generally, overnight boiled water will cause bacteria to grow if it settles overnight. If the water is boiled to 100 degrees Celsius, it will kill many bacteria and viruses. However, as the water level decreases, it will favor the growth of bacteria and viruses.

If the weather is hot and humid in summer, and the ambient temperature is high, it will be more conducive to the growth of bacteria. It's time to pay more attention.

2.Generally boiled water settles overnight. Generally, there are not too many bacteria, but if you leave the water overnight for a long time, there will be more bacteria.

Moreover, drinking water overnight often will cause abdominal pain, diarrhea and diarrhea. Water cannot be drunk overnight. To prevent causing abdominal discomfort.

You can usually store the water in a thermos cup, so that it will not cause abdominal discomfort. It can be of some help.

The reason why the overnight water can not be drunk is because the boiled water is left for too long, it will be easy to breed bacteria, if the temperature is too high, it will be easy to deteriorate, and it will easily cause diarrhea after drinking, especially for children or the elderly with weak stomach, it is best to drink fresh boiled water.

Many people usually drink water, they like to drink overnight water, in fact, this is the wrong approach, because the water that has not been drunk will be easy to breed bacteria under a long period of placement, if the cup is not covered with a stuffy section, such as combustible can lead to the entry of dust, so that after drinking it will increase the burden of liver function, which is not conducive to health.

At the same time, the temperature is very high in summer, if the water is placed for too long, the bacteria in it will multiply quickly, which will pollute the environment of the water, and it will easily cause diarrhea after drinking, so for the sake of safety, it is generally not recommended to drink the water after overnight, and it can be stored in a thermos bottle if it is not finished.

Generally speaking, boiled water should not be left for too long, if it is a few days of water, it is not recommended to take, and the water on the water dispenser is best to drink it within a week, especially for people with fragile stomach or pregnant women and weak bodies, it is best to drink fresh boiled water to ensure the healthy development of the human body.
