Can water be boiled repeatedly Can you drink boiling water after boiling for a long time

Boiling water that has been boiled for a long time is not drinkable. Because boiling water that has been boiled for a long time or boiled water many times (some people also call this water a thousand boiling water, refers to the water that has been repeatedly heated in the water dispenser or kettle. The nitrite content in it will be higher.

A large amount of nitrite can directly poison people, because nitrite acts with human blood to form methemoglobin, so that the blood loses its oxygen-carrying function and makes people hypoxic poisoning. Although the nitrite content in the boiling water is not so high, when nitrite reaches a certain dose in the human body, it is a carcinogenic, teratogenic and mutagenic substance, which can seriously endanger human health. So, try not to boil the water repeatedly.

It is also best to "drink and burn" the hot water of the water dispenser, and do not keep it in the state of "heating - heat preservation" all the time.

Water that has been boiled for a long time has low oxygen content. In addition, the water will harden because it is burned for too long, and drinking it is not good for people, and it is easy to cause stones and other diseases.

Of course, try not to drink boiled water overnight.

Overnight boiled water contains nitrite.

Nitrite can form carcinogenic nitrosamines in the human body. Some experts have found that the nitrite content in boiled water is higher than that in raw water. Moreover, the nitrite content of boiling water that has been boiled for too long or more than 24 hours has been boiled for many times.

After 24 hours of boiling water, the nitrite content is twice that of the first boil. Chinese residents have the habit of drinking boiled water, and it is best to drink it freshly or only drink the boiled water of the day. Also do not drink boiled water that has been boiled for too long.

Is it true that repeatedly boiled water is high in nitrite and cannot be drunk?

Nitrite in water is not produced in a vacuum, but is generally converted from the original nitrate in the water. There is very little nitrate in qualified drinking water; However, if the water source is contaminated with nitrogenous organic matter, the nitrate level may increase, depending on the situation.

Repeatedly boiled water can be drunk, but it is not advisable to drink too much, but if you do not drink it in the morning and boil it again in the afternoon, this practice is okay and will not hurt your body.

"Thousand boiling water", that is, water that has been boiled for too long or repeatedly boiled, should not be drunk. It can cause gastrointestinal dysfunction, as well as poisoning, hypoxia, coma, system lesions, and premature aging.

Repeatedly boil the water because.

The calcium, magnesium and other heavy metals and nitrite in the water cannot be boiled and volatilized, and the concentration becomes higher by boiling for a long time and repeatedly boiling, which is easy to cause gastrointestinal dysfunction, resulting in diarrhea and bloating; Among them, nitrite can also cause hypoxia, poisoning, and even death from coma. If you drink water that has been boiled and reused repeatedly, scale will also enter the digestive, nervous, urinary, hematopoietic and other systems of the human body, causing lesions.

Of course, you can't drink it, because if you boil the water repeatedly, some insoluble minerals and some impurities will be formed in it, which will cause certain harm to the body.

It is better not to go to the water that has been boiled repeatedly, and it is better not to drink the water that has been boiled to work, and if you drink it, it is still not very good for the body, stomach and intestines, so it is better not to drink the water that has been boiled repeatedly.

See what kind of water your raw water is and what substances it contains. If the raw water is surface water, it is recommended not to drink it after repeated boiling, because repeated boiling of surface water is easy to produce carcinogens nitrites, which is not good for health. If it is groundwater, the situation may be a little better, but the situation is different in each region.

It is recommended not to boil it repeatedly before drinking.

Repeatedly boiled water can be drunk, but repeatedly boiled water is hard and does not have much nutrition, and children can also drink it.

After boiling the water several times, the water quality changes and the water quality can no longer be consumed, and continuing to drink it will cause bad effects.

Why drink boiled water repeatedly? It's not necessary and it's not interesting.

However, if it is boiled a second time, I don't think it is a big problem.

Boiling things repeatedly, in fact, is a lot in life. For example, boiling soup or stir-frying vegetables will volatilize a lot of water. In this way, it should be no problem to boil less water for the second time.

If you boil a pot of water and leave a glass of water, I think it's better not to drink it.

This is my point of view, not necessarily scientific.

Thank you for your question.

Repeatedly boiled water cannot be drunk, and poisoning will occur. Repeatedly boiled water contains acidic alkali, which can have a carcinogenic effect, because nitrate from the water may be converted to nitrite, which can have a great impact on the body's health. Drinking water that is repeatedly heated in the water dispenser or kettle, a small number of patients will experience nausea, vomiting, bloating, diarrhea, and some will have the best diseases, which should be reduced, and it is best to drink more plain water.

Don't drink it, after all, the impurities and heavy metals in the water will be concentrated.

It is not particular about drinking, and it is boiled repeatedly, which is not much different from our common stew, or boiling.

I think I can drink it, just like the old fire soup, it is boiled repeatedly, and the taste is very good.

1. Primary dysmenorrhea.

If there is no organic lesion of primary dysmenorrhea and the symptoms are relatively mild, it can be relieved by psychological **, relieve tension and anxiety, maintain a regular life, avoid coffee, alcohol and strong tea and other drinks, and exercise appropriately. If the dysmenorrhea is severe, it is necessary to gradually relieve the pain through local hot compresses, massage, etc., and in severe cases, painkillers can be taken to relieve the pain.

If you drink purified water, distilled water, and deionized water, it basically does not contain impurities, no matter how you boil it, the water is still water, and it will not become other substances.

1. The nitrite content in the boiled water is below the limit, and normal use will not cause poisoning or death.

2. If the water that has been boiled repeatedly for a long time, it is recommended not to drink it due to the breeding of microorganisms.

Water that has been boiled repeatedly will have a higher mineral content. It is best not to drink it, otherwise it is easy to get gallstones.

It's not that boiling water can't be boiled a second time, but it shouldn't be boiled many times. Repeatedly boiling boiling water, calcium ions in the water are easy to precipitate and form calcium carbonate, and long-term drinking is easy to form kidney stones.

In addition, the water also contains a small amount of heavy metal ions such as copper, magnesium, lead, etc., which are precipitated and deposited in the water after repeated boiling, which will increase the burden on the kidneys, affect kidney function, and affect the growth and development of children and adolescents.

It can also aggravate the kidney damage of patients with chronic kidney disease, so patients with diabetes, high blood pressure and other kidney disease can damage the kidney as much as possible, and try not to drink boiled water repeatedly.

In general, you should definitely drink less or no water that has been boiled repeatedly.

Of course not, boiling water should not be boiled all the time.

You can drink it, but it's best to drink it sparingly.

It is best not to drink water, and try to boil it once.

Is it true that repeatedly boiled water is high in nitrite and cannot be drunk?

1. It is not recommended to drink water that has been boiled repeatedly, because after the water is boiled repeatedly, the nitrite in it will increase, causing harm to the health of the body.

2. If the boiled water has been left for a long time, it will breed a lot of bacteria and microorganisms, and even if the water is boiled, there will still be some odor and bacteria left, so it is not recommended to drink it.

Can't drink it. Water looks pure and transparent, but in fact, there are many things dissolved in the water, including calcium, magnesium and nitrates. After repeated boiling of water, the concentration of calcium and magnesium ions in the water will increase, and nitrate will turn into nitrite, which has carcinogenic effects.

Drinking too much boiled water can cause abdominal pain and diarrhea. If you drink this water for a long time, you are also susceptible to cancer.

Introduction: I used to think that as long as the water was boiled no matter how many times it was boiled, I could drink it, but then I found that this was not the case, and I tried not to drink the water that was boiled repeatedly. Water is boiled and burned to increase the water again, and the content of nitrite will also increase, often drink this water nitrite will accumulate in the body, which will cause poisoning, and may cause cancer, so it is recommended that you can burn less when you usually boil water, and then burn it after drinking, so that you can drink very fresh water, and there will be no other carcinogens in it.

In fact, most people keep boiling this water and burning, that is, they are afraid of wasting, but we must know that drinking too much boiled water will also affect our health, if we drink pure water, distilled water deionized water, it does not contain impurities, no matter how much water is boiled, the water contained in the water will not become other substances, but you must know that after the water you usually drink is boiled many times, it will decompose the original nitrate into nitrite, which is more toxic than nitrate. Excessive intake of nitrite will destroy the oxygen-carrying capacity of hemoglobin, resulting in a lack of oxygen in the body, and it is a carcinogen, and long-term intake is likely to cause cancer, so it is recommended that you usually drink as much as you can burn.

Everyone should pay attention, usually boil water not to boil too much, after the first boil try to drink it to him, if you can't finish it, don't boil it again, it can be used in other places, and the water can't always be boiled repeatedly, if you always drink it, you may have dizziness or poisoning reaction, it is recommended that you drink it directly after the water is boiled, otherwise it will be used for other purposes, anyway, this water should not always be boiled repeatedly. And you have to know the shelf life of a glass of water, he is actually only 16 hours, and the number of germs in overnight warm boiled water is more than that in drinking water. After the water is boiled, try to drink it within 16 hours.

It is not allowed to drink, and the mineral elements in the water will be destroyed after repeated boiling, producing harmful elements, which is not good for the human body, so it cannot be drunk.

Repeatedly boiled water is not drinkable. Because there may be some impurities in this water, and there is also the possibility of bacteria breeding. So I can't drink it.

You can't drink it, such water will be problematic and will cause poisoning, so you can't drink it.

The nitrite content of repeatedly boiled water is still within the normal range and will not cause harm to the human body.

Water is an indispensable and important substance for human survival People can go without food for a day, but they can't go without water for a day Many people say that you can't drink water that has been heated and boiled many times Is this really the case?

If not, why can't you drink water that has been boiled repeatedly? There are different reasons for this, but in summary, there are about three kinds. One is that after the water is boiled many times, the dissolved oxygen in the water runs out, and drinking oxygen-deficient water is not good for health.

We humans are not fish, we do not absorb oxygen from water, but by breathing.

Another theory is that if the water is boiled for too long, the scale will dissolve into the water, and the concentration of heavy metals such as calcium and magnesium in the water will increase, making the water hard, which is not good for health.

It's better not to, but it's not too toxic.

Can you still drink boiled water repeatedly?
