We are all drinking overnight boiled water, is it okay to drink overnight boiled water?

Overnight boiled water should not be drunk, because some of the substances in it have deteriorated, and it is not suitable for drinking, which is harmful to the human body.

I think it's okay to drink boiled water overnight, I often drink boiled water overnight, and there are no problems with my body, so I don't think there's anything wrong with drinking boiled water overnight.

Overnight boiled water can be drunk, the reason why some people are worried that overnight boiled water can not be drunk, is because there are Internet rumors that it contains excessive nitrite, but scientific experiments have proved that the nitrite content of overnight water is very, very low, far lower than the amount of leftovers or pickles that are often eaten, and overnight water will not cause any harm to the human body, so there is no need to worry too much.

Overnight boiled water can be drunk. Because overnight boiled water has not passed its expiration date and is not damaged, it can be drunk.

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?

Can you drink plain water overnight? It's good to be clear as soon as possible, don't be a deaf ear, and look at the knowledge.

It's okay, we're all Chinese, milk powder, steamed buns, pork haven't eaten us to death, I'm afraid of a little overnight water, believe me, it's okay.

Isn't it possible that you drink water freshly boiled and drunk? It's okay.

The water quality of overnight boiled water** itself meets the safety standards and can be drunk, but overnight tea cannot be drunk.

If there is no material basis in the water overnight, carcinogens will not be born out of thin air. The carcinogen that people are most worried about - nitrite must be produced on the basis of nitrate, but ordinary drinking mineral water or purified water either has only minerals and trace elements, or nothing at all, in this case carcinogens are not born out of thin air.

As long as the water quality itself can be guaranteed to meet safety standards, no matter how much the water is burned, it will not produce carcinogens. However, overnight tea will produce amino acids and other substances, which can easily lead to the reproduction of microorganisms for a long time, and should not be drunk.

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.

"Overnight water can't be drunk" is mainly because overnight water contains chemicals such as zero alcohols, oxyphenols, and hydroxyhydrogen, which can cause diarrhea and even produce carcinogens nitrite.

, overnight boiled water is best to drink less or no Guidance: 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 from 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 you drink boiled water overnight? Drinking water should also pay attention to these methods and hygiene.

OK. 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 say that overnight water is poisonous and even carcinogenic, citing the problem of containing "nitrite".

Because the production of nitrosamine substances requires a suitable environment and precursor substances, but the bacterial substances in the water will lose their activity after boiling, and the nitrate content is small, and there is no basis for the production of a large number of nitrosamine substances.

So, overnight boiled water is drinkable.

Drink water safely and healthily.

1. As long as the water you drink is clean, qualified and safe, you can drink it with confidence.

2. Drink water, don't stick to "8 cups of water", the size of the cup is different, and the amount of water you drink is naturally different.

3. Pay attention to hygiene, don't drink "raw water".

4. Do not drink hot water and ice water, and the water temperature should be "suitable".

5. Drink slowly, don't "drink a lot of water at once".

6. Don't wait until you're thirsty to drink water.

7. Look at advertising reasonably and don't be obsessed with "concept water".

Popular Science China "Thousands of boiling water cause cancer, overnight water is toxic? Don't panic! The truth is here

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.

Some Weibo netizens said that after three days of storage of boiled water, nitrous acid can be produced, which can make people dizzy, nauseous and vomiting after drinking. If it is stored for a longer time, it will combine with amines and become ammonium nitrite, which will promote stomach cancer, liver cancer, and esophageal cancer. Bottled mineral water and purified water are the same for more than 3 days, and bacteria multiply in large numbers, which is not as good as tap water.

After the rumors passed through netizens**, the more "evil" they became.

Liu Wenjun, a professor at Tsinghua University's School of Environmental Sciences, thinks this statement is a bit alarmist. In fact, the amount of nitrite in the water is very small, and it is usually oxidized to nitrate, so this claim is unfounded. In fact, boiling water is a good habit of the Chinese people, which can greatly protect the health of the body, play a good role in disinfection, and kill the pathogenic microorganisms.

Therefore, boiling water is necessary for China, especially when the drinking water safety is not particularly good. When bottled water is opened for a long time, it can be contaminated by microorganisms, which may cause diarrhea, but it will not cause cancer. There is no basis for the claim that nitrosamines are produced.

Hehe, of course you can.

You can drink it without heat, within 24 hours.

Drink it casually, it's called cold white open.

24 hours away, we don't have to save so much, right?

It is best to drink freshly boiled water or only boiled water of the day, preferably not for more than 24 hours. After boiling water for 24 hours, the nitrite content is twice that of the boiling, the nitrite in the water is excessive, exceeding, will cause physical fatigue, fatigue, drowsiness, coma and other conditions, for their own health, it is better not to drink overnight water.

Overnight water is not very harmful to the body, but the water still can not be placed for a long time, because the process of long-term water placement may lead to a large number of bacteria and microorganisms, which will seriously affect the water quality, if you drink water for a long time, it may cause the metabolism of bacteria to be slow, accelerate the aging of the human body, and it is easy to induce gastric cancer and esophageal cancer. The shelf life of unopened bottled water is three months, and once it encounters air after the start of work, it is best to drink it within 15 days.

The distilled water sold on the street is boiled water every other month.

It can be drunk, as long as it has been opened, it has been sterilized, and it has just become cold overnight, and it has no other effects.

If you can't drink it, will you still let people run it "cool and white"? Boil water overnight, don't get dusty, it's drinkable.

Boiling water is fine, but opened milk is not.

Is it overnight boiling water poured in a cup ?? Don't drink it! ~

Definitely not, there is still nitrate in it. If it continues to boil, it will be even more harmful to the human body.

The so-called bacteria theory is pure nonsense and pseudoscience, what microorganisms can be bred in plain water? Cool white open nutrients are very few, which is not suitable for bacterial reproduction. The correct way to say it is that after being left overnight, it is stagnant water and loses its biological activity; Still and passing through the night, the yin qi is heavy, and there is no yang qi.

This has nothing to do with sealing or open storage, the seal is still inactive, and the yin qi will be heavy, and the yang qi will be dissipated.

Can you drink cold boiled water overnight? .As long as it is not exposed cold boiled water, it is completely drinkable, and there are benefits, exposed cold boiled water will fall into bacteria and dust and be easily contaminated, so it cannot be drunk.

Water is an indispensable substance for the human body and all plants and animals on the earth to sustain life. With 71% of the Earth's water resources and about 70% of our body weight, you can imagine how important it is. A person can go three days without food, but three days without water can be life-threatening.

The same is true for animals and plants, and without the nourishment of water, there would be no beautiful earth! Before talking about whether the water can be drunk overnight, let's talk about the benefits of drinking water!

The benefits of drinking water for people.

If you drink a glass of water before meals, especially the first cup in the morning, you can reduce the amount of food, which can help you control your weight and reduce the chance of gaining weight! Cold boiled water is best because it is easily absorbed and can consume a lot of calories in the body, thus achieving a fat reduction effect! Moreover, the aging of the human body is the reduction of water in the body, resulting in dryness, at this time, it is necessary to replenish more water to prevent water loss and let it age!

Clause. 5. How to drink water.

It is generally recommended to drink a glass of water in the morning, which can not only dilute the blood but also promote physiological effects! Drink a glass of water before going to bed, but not too much, people will naturally sweat during sleep, losing water and salt. And sleep can't replenish water, so many people get up thirsty, it's lost at night!

Moreover, it is very advantageous for the elderly to get up early to drink water, which can prevent the occurrence of many diseases!

Okay, after talking about the benefits, let's talk about whether the overnight water can be drunk.

Someone has done experiments and said that overnight boiling water, the pH value and trace elements in it are all in the normal range, and they can meet the standard of drinking, and there is no *** to drink! However, some people have investigated and said that try not to drink, if you leave it for a long time, the nitrite in it may increase, which is a carcinogen, and it is not good to drink it for a long time! So try not to drink overnight water, and drink less if you have to drink it!

The above is the role of water, but anything is too much must be the opposite, and people drink water the same, as long as you ensure 2500 to 3000 ml a day, more will increase the burden on the kidneys, and many trace elements will also be washed away! But if you want to be healthy, you can't do less than 8 glasses of water a day! Of course, it's best not to drink water overnight or drink less!
