    Overnight water can be a problem for bacteria to grow.

    But ice in the refrigerator overnight water can reduce bacterial growth.

    Because overnight water is easy to breed a large number of bacteria, it is not beneficial to human health, but some people know that they still often drink overnight water, which is really bad.

    Although tap water has been disinfected and filtered, there are still certain bacteria, boiling water overnight, 37 o'clock is the most likely for bacteria to grow and multiply, and the nitrite content in the water will rise overnight, drinking this water is easy to cause disease, so a pot of water for three days is a bad habit.

    Many people have a cool bottle of water at home, and the cool boiled water in it can be drunk at any time. However, this convenience can pose health risks. If you don't finish it that day, be sure to pour it out.

    This is because nitrogen-containing organic matter in boiled water 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.

    In addition, many families are now accustomed to drinking bottled water, and seemingly well-sealed bottled water should be drunk within three or four days. Because, after the bottled water is opened for a long time, bacteria will slip into the water inlet, and the water dispenser will form a negative pressure when the water is discharged, and it will inevitably inhale part of the air, and the bacteria and microorganisms in the air will also take advantage of the void to enter. If you don't drink it in a short period of time, the bacteria will exceed the standard and the purified water will no longer be pure.

    Overnight boiled water is drinkable. Some people think that boiled water cannot be drunk overnight for two reasons: first, a large number of bacteria are present 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.

    Many people have certain doubts about whether overnight water can be drunk, but in fact, overnight water does not cause cancer, and it is okay to drink! Let's talk about it in detail.

    Overnight water refers to boiling water that has been left on hold overnight, so can you drink overnight water? Is it really harmful?

    Can you drink water overnight?

    Some people say that overnight water is poisonous and even carcinogenic. The reason for this is still the problem of "nitrites", nitrosamines are indeed a new type of drinking water disinfection by-product, but the amount of nitrosamines we ingest from drinking water is actually "minimal".

    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.

    Therefore, even if the boiling water is left overnight, it will not change the properties of the water itself, and the microbial content may increase, but it will not cause great harm to the human body.

    There is an argument that overnight water produces nitrite, which is a strong carcinogen, so overnight water becomes carcinogenic water, which in the eyes of some people is comparable to poison. However, studies have shown that drinking water does contain small amounts of nitrate and nitrite, but the levels are very low and do not pose a threat to the human body. Nitrate and nitrite are mainly used in formations, domestic sewage and industrial wastewater, but after the treatment of drinking water, its content has been very low, although the night is dark and mysterious, but it does not make the nitrate and nitrite in the water increase out of thin air.

    Therefore, this claim is completely unfounded.

    Overnight water and water that has been boiled for a long time should not be drunk because it 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.

    In addition, overnight water increases the multiplication of a lot of bacteria due to its lower temperature. Harmful to the body.

    Don't drink water boiled overnight, which means that the water has been boiled for a long time.

    According to China Sports News, water is an important part of the human body and one of the most nutritious people. Scientific research has confirmed that people can not starve to death if they do not eat food for 20 days as long as they have water, but if they do not have water, they will die of dehydration in 3 to 7 days. In order to ensure good health, we must pay attention to scientific drinking water.

    1. Drink water regularly, don't think about drinking water only when you're thirsty. It is important to know that when the body specifically wants to drink water, the body's organs are already operating at a limit, that is, there is a great shortage of water, and it should be replenished long before the body wants to drink water. Experts recommend that it's best to get into the habit of drinking water regularly.

    2. Drink plenty of boiled water, not raw water. Boiling water for 3 minutes can evaporate the chlorine and some harmful substances in the water, and at the same time maintain the necessary nutrients for the human body in the water. Drinking raw water is harmful because the chlorine in tap water can interact with the remaining organic matter in unboiled water, which increases the chance of bladder cancer and rectal cancer.

    3. Drink fresh boiled water, not water that has been left for too long. Fresh boiled water is not only sterile, but also contains more than a dozen minerals needed by the human body. However, if you drink water that has been boiled overnight in an automatic water heater for too long, not only will it not be able to contain various minerals, but it may also contain some harmful substances, such as nitrite.

    The resulting nitrite poisoning is not uncommon.

    It seems that you can't drink tea overnight. Herbal tea is not good for the body, especially for the elderly.

    Bad tea contains theophylline, caffeine, xanthine, tannic acid and trace element fluorine, which are beneficial substances for the human body. In addition, it also contains tea polyphenols, which are easily oxidized into a brown gelatinous substance in air and water - tea rust. Tea rust contains a variety of substances such as pickaxe, lead, iron, arsenic, mercury, etc.

    The longer the tea is exposed to the air or left in the teacup for a long time, the more the amount of tea polyphenols oxidized into tea rust will be. Tea rust enters the human body, binds and precipitates with proteins, fats and vitamins in food, hindering the absorption and digestion of nutrients. Once these oxidizing substances enter the human body, they can also cause inflammation, ulcers, necrosis and other lesions in organs such as kidneys, liver and stomach.

    Tea should not be drunk overnight, and tea utensils should also be scrubbed frequently.

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.

    Drinking as much water as possible is hard to burn. Some of the rest of the water is more realistic. Is it true that you can't drink water after a night? Does the carcinogenic theory really exist? Drinking water should know these things.

    Is overnight boiled water a carcinogen?

    Most of the articles on the Internet about "overnight water causing cancer" refer to "nitrite", but the premise of nitrite production is that "the substance contains nitrate". Specifically, some substances contained in drinking water such as boiled water, purified water, and mineral water are only mineral elements, and there will be no "carcinogenic reaction".

    Water is a "pure substance" with no particular "point" of nutritional value. As long as the water source can meet safety standards, the water quality is hygienic and safe, and no carcinogens will be produced when burned, you can drink it with confidence.

    This matter needs to be treated by everyone. The claim that "overnight water is toxic" is no longer "news". However, such a theory must have a "scientific principle" to be valid.

    Nitrate does exist after boiling the water nitrite, but this "dose" is very limited and does not reach the "toxic dose" at all. It would be irresponsible to talk about the effect (toxicity) without considering the content.

    And then "Can you drink boiled water overnight?" ”?

    We should treat this issue differently. If the water you are drinking is a hygienically safe glass of water and then has been properly stored (with the lid intact and not kept for too long), then this water is definitely drinkable.

    Conversely, if your overnight water is exposed to air overnight, it is not recommended to continue drinking it from a hygiene point of view. After all, dust and impurities can contaminate your glass of plain water.

    Note that there are two types of water that are not drinkable:

    Raw water: Water that comes into direct contact with metal pipes is likely to be contaminated with harmful substances such as parasites and bacteria. Ingestion increases the risk of food poisoning, so it should not be consumed.

    Water that is not completely boiled: Tap water that is not boiled is easy to exceed the standard, which will bring some harm to the body. When the water is boiled to 100 degrees Celsius, most of the harmful substances in the water will evaporate with the steam. Therefore, you should be careful when drinking water:

    Drinking water, safety and hygiene are paramount; Therefore, please drink "boiling water, boiling and warming".

    The drinking water should meet the standard, and the daily intake of boiled water should be at least 1500-1700 ml.

    Drink water, pay attention to the temperature, drink boiled water close to body temperature, harvest health, the maximum temperature is not recommended to exceed 65 degrees Celsius.

    Drink safe water that will not cause harm to the body; Drink every glass of warm water with a scientific attitude, and wish everyone a warm harvest in the cold autumn.
