Can you still drink it after the overnight coolness?

First of all, it is necessary to figure out what is cool and white, the so-called"Cool and white", refers to a kind of water obtained by boiling water and then letting it cool naturally. This is what we often call plain water.

After the natural cooling of boiling water, the physical and chemical properties such as density and conductivity of water will be changed, and its biological activity is 4-5 times higher than that of natural water, similar to water in the membrane of living cells. Therefore, it is easy to be absorbed by the human body through the cell membrane, promote metabolism, increase the hemoglobin content in the blood, and improve immune function. If you drink it regularly, it can also prevent colds, pharyngitis and some diseases.

Of course, the water source for cool boiled water must be of high quality.

Can you drink it on the night of quarantine Many people think of the word nitrite to see if there is this substance after overnight?

Yes, but in very small quantities and will not have any health effects.

Nitrite is not produced out of thin air, but is converted from nitrate in water under certain conditions:

Thermal decomposition: When drinking water is repeatedly heated, nitrate can be thermally decomposed and converted into nitrite;

Bacterial contamination: Drinking water is left in the air for a long time and reduced to nitrite under the action of microorganisms. <>

In 2006, China's newly revised "Drinking Water Standard" (GB5749-85) clearly stipulates that the index limit of drinking water nitrite is limited to 10 milliliters, taking into account the specific conditions of different regions, and specifically stipulates that it can be relaxed to 20 milliliters when the use of groundwater and other conditions are restricted.

Drinking water that meets this standard, even if it is boiled and left to dry overnight, produces very little nitrite, does not cause cancer, and does not cause health damage.

It is a glass of water that you can drink if you want, and it is also a good choice to pour out and water the flowers if you have psychological disorders.

For human health, the best drink is cold and plain. Drinking a cup of cold boiled water when you get up in the morning can enhance the liver's detoxification ability and kidney drainage, promote metabolism, increase immune function, help lower blood pressure and prevent myocardial infarction. If you drink it regularly, you can also prevent colds, laryngitis and some diseases, of course, the water source of cool boiled water must be a high-quality water source.

However, if it is placed in a cup and left for an overnight rest, it absorbs carbon dioxide from the air, which is generated.

The carbonic acid will slightly lower the pH of the water and change the taste, which will have some sour taste, but will not harm health.

In addition, when drinking water, saliva and bacteria in the mouth enter the water cup, and they multiply in large numbers at the right temperature and environment. Compared with boiled water that has just been boiled and cooled, the quality of overnight water and boiled water after more than ten hours is indeed not as good as before.

When the boiling water is cooled to room temperature, the microorganisms in the air begin to multiply in the water. And the longer it takes, the more microorganisms will multiply in the water, so people with weak stomachs and small children should not drink overnight water.

Five. It is best to drink less or no overnight boiled waterGuidance: If 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 severe cases, it can also cause people to die of hypoxia.

Nitrite can also form nitrosamines in the human body, which can promote liver cancer and stomach cancer. Of course, these are extreme situations and generally do not appear, but for the sake of health, try not to drink overnight water.

Can I drink cold white after it has been open for a long time? Experts say that there is no fixed time for how long water will deteriorate, and it is mainly affected by external objective environments such as temperature. In summer, the air humidity is high and bacteria multiply quickly, which can easily pollute water and cause human diarrhea.

Therefore, it is best not to drink overnight water in summer, and it is best to keep overnight water in winter in a container with a lid (such as a thermos). Boiling water should not be left for too long, the nitrate in the water will be reduced to nitrite by some reducing bacteria in the air, although the amount is not large, it is difficult to cause poisoning, but it is better to drink less, and it is best not to drink the water after a few days. Bottled purified water, it is generally recommended to drink it within a week.

You can still drink it overnight, and the reason analysis is:

There are no special substances in the cool boiled water, and even if it is separated overnight, it will not produce undesirable substances that damage the body, so you can drink it with confidence. But be careful to close the lid, otherwise there will be dust or small bugs in the water, and you really can't drink it. So, you can drink cool boiled water overnight! <>

Overnight boiled water is drinkable, and the reason why some people are worried that overnight boiled water cannot be drunk is because there are Internet rumors that there is an excessive amount of nitrite. However, scientific experiments have proved that the nitrite content contained in overnight water is very, very low, far lower than the amount of leftovers, leftovers, or pickles that are often eaten, and will not cause any damage to the human body, so there is no need to worry, some people think that boiled water cannot be drunk overnight, because of two reasons: First, a large number of bacteria exist in it.

2. Overnight boiled water is carcinogenic. Actually, it's all wrong. Overnight boiled water contains a certain amount of bacteria, but not a lot, and drinking cold boiled water has many benefits for the body, and there is no guarantee that there are no bacteria in the water, just a matter of how much.

If you leave plain water for more than two days, don't drink it, but overnight, that is, 8-12 hours, is no problem. There is also boiled water after repeated decoction before it can cause cancer, but it must be decocted more than 35 times, which is not possible for ordinary families. Therefore, overnight boiled water is not harmful to the body, and it can be boiled again if necessary, and it can be drunk after boiling.

Drinking plenty of water can make the osmotic pressure in a person's body more stable, which is good for a person's health. Diluting toxins in the body and drinking warm water is conducive to speeding up metabolism, thereby increasing the metabolism rate of waste products in the body; It can dilute toxins in the body and is beneficial to human health; It keeps it moist. Drinking warm water can keep it moist and elastic.

The activity of low-temperature boiling water can also increase the activity of dehydrogenase in the human body, which is beneficial to reduce lactic acid in the muscles called "fatigue hormone", so that people can recover their strength and energy as soon as possible. <>

It is not allowed to drink, and if it is cooled overnight, there will be a lot of bacteria produced, which is not conducive to the healthy development of the body and will lead to fungal infection.

It is best not to drink it, because it is easy to cause bacteria to multiply, which can easily lead to gastrointestinal problems, which will lead to diarrhea and bring harm to the body.

Overnight cool white open is still drinkable, if it is tea water or something added to it may deteriorate, so try not to drink it after overnight. The premise is that it must be sealed well to avoid the breeding of some bacteria or mosquitoes falling in, there will be some bacteria, so such water cannot be drunk.

Many people will have such thoughts, overnight meals can not be eaten, and also think that overnight cold white open can not be drunk, as long as it is placed in a thermos cup and sealed in advance, such water can still be drunk. The reason why you can't eat overnight meals is because there is salt in it that will turn into nitrite, which has an impact on people's health, and if there are no other substances in the boiled water and there is no bacterial growth, such water can be drunk.

We all know that nitrite is harmful to the human body, so it is very bad for health, and the storage time is longer, the more content it will have, especially for overnight meals, but the nitrite content in the overnight lymphatic journal is relatively low, and it will not cause too much harm to the body, but the overnight cool white drink is not particularly fresh, which will affect the taste, so many people will choose not to drink this boiled water. Generally, water is filled with a thermos cup or a water cup with good sealing, and there will be no peculiar smell, but many people have a sensitive sense of taste.

Drinking such water will find that the water has deteriorated, and if it is stored for too long, carbon dioxide will enter, and some carbonic acid will be produced in the cool white boil, which will also have an impact on the body, but it is not particularly large. Be sure to look at the time before drinking cold boiled, too long will affect the taste, and make sure that there is some boiling water in the kettle, there will be no health hazards or reheating. When some dust or bacteria in the air enter the water, there will be some harm, bacteria may breed more, and there will be diarrhea after drinking, this kind of water will affect people's health, so we should pay attention to health problems.

Bacteria multiply relatively quickly, and overnight cool, which loses its biological activity, will be easily contaminated. Therefore, it is not recommended to drink, if the time is not very long, it is possible to drink overnight water, and the microbial content may increase, but it will not cause great harm to the human body.

In the process of standing, the cool white boil will absorb carbon dioxide in the air, and the resulting carbonic acid will reduce the pH value of the water slightly, although it will affect the taste, but it will not harm health.

I don't think you can drink it because there will be a lot of bacteria in it overnight, and if you drink it, it will cause poisoning.

If it has not been contaminated, it can still be drunk. The doctor is also for the sake of our health, so we are not allowed to drink the cool white water of the night leaves.

Can you still drink it after the overnight coolness? Why don't doctors recommend drinking it?

After the cool white boil is boiled, it has ensured its own cleanliness, and it can be drunk even if it is left overnight without being polluted. But as a doctor, they have a lot more professional knowledge than us, so they know that Gree's boiled water is very harmful to the human body, so the doctor does not recommend everyone to drink the overnight cool boil, after all, they are afraid of happening.

It is recommended that boiled water should not be left on for more than 24 hours

In normal life, if the temperature is not very high, and then the boiled water is kept, then it is okay to drink it when you get up in the morning on the second day and mix it with an appropriate amount of boiled water. However, in the absence of closure, there may be some microorganisms multiplying in the boiled water, so in this case, if the human body drinks it, then the impact on health is great. Therefore, when there is only plain water, it is recommended not to take more than 24 hours of shelving water!

Overall, the longer the cool white is exposed to the air, the greater the chance of bacterial infection. The water quality will also get worse and worse, and if you drink it, then there will be a lot of harm to the body. Mild cases may be diarrhea and stomach pain, and severe cases may require hospital treatment.

Therefore, in real life, in order to maintain a good living and eating habits, it is best for us to drink fresh cold white water, which is more beneficial to health. If you don't like to drink boiled boiled In real life, would you drink overnight cool white water?

It should be drinkable. Because the doctor felt that there were a lot of bacteria in the cool white open overnight, which did not do any good to the body and would cause diarrhea.

I can't drink it anymore, because there may be some bacteria in the cool white boil, and there will be some microorganisms. If you drink water overnight, then it may lead to the accumulation of viruses, which may lead to the detection of some diseases.

I don't think so, mainly because it reacts with the air. It will cause deterioration of cold white open, and diarrhea will occur after drinking.

Overnight cold white open can not be drunk. The nitrogen-containing organic matter in the boiled water for a long time will be continuously decomposed into nitrite, and at the same time, it is inevitable that the intervention of microorganisms will accelerate the decomposition of nitrogen-containing organic matter.

The harm of nitrite to the body is well known, it has a strong ability to bind to hemoglobin in the body, which can hinder the normal oxygen transport function of the blood. Therefore, it is best to drink boiled water on the same day.
