Eight kinds of water that can't be drunk There are different opinions about whether water dispensers are toxic or not, but regardless of right and wrong, we must achieve healthy drinking water, and remember that eight kinds of water cannot be drunk. Raw water: Chlorine in tap water can interact with residual organic substances in unboiled water, which can easily lead to bladder cancer and rectal cancer; Raw water in the wild contains harmful bacteria, viruses and parasites, and after drinking, it is easy to get acute gastroenteritis, hepatitis, typhoid, dysentery and parasitic infections.
Unboiled water: Drinking unboiled water increases the likelihood of bladder cancer and rectal cancer by 21%-38%; When the water temperature reaches 100 degrees Celsius, the harmful substances will be greatly reduced with the evaporation of the steam, and if it continues to boil for 3 minutes, it is much safer to drink. Re-boiled water:
If the boiling water is boiled again, the nitrite content in the water will exceed the standard, causing damage to the human body and causing cancer over time. Water in the air for a long time: Cool boiled water should not be exposed to the air for too long, otherwise it will lose its biological activity and thus lose many special functions; If the time is too long, not only will various minerals be lost, but also the content of certain harmful substances may be increased.
Overnight water: Filled in a thermos is not the boiled water of the day, similar to water that has been left in the air for a long time. Aged water:
That is, water that has been stored for a long time, and drinking this water often will significantly slow down the cell metabolism of minors and affect their growth and development; Accelerated aging in middle-aged and elderly people; As a result, the incidence of esophageal cancer and gastric cancer is increasing. Boiling water: Boiling water is boiling water that has been boiled overnight or for a long time on the stove, and water that has been boiled repeatedly in an electric water heater.
Drinking this water for a long time will interfere with people's gastrointestinal function, causing temporary diarrhea and bloating. Steamer water: Steamer water is the boiling water left at the bottom of the pot for steaming steamed buns, meals and other foods.
Drinking this kind of water, or boiling porridge with this water, will cause nitrite poisoning, and scale often enters the human body with water, which can cause diseases of the digestive, nervous, urinary and hematopoietic systems, and even cause premature aging.

If you put it in a thermos flask, you can drink it, and if you don't put it in a thermos, you can drink it, but if you drink it is not good for your health, overnight boiled water, there are more bacteria, and if you want to drink it, you can boil it at the time!!
-
Can't drink it. 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, and is also prone to cancer.
Water has a shelf life, and drinking raw water is easy to have diarrhea, because there will be various microorganisms and bacteria in the water, and after boiling at high temperatures, these microorganisms and bacteria cannot survive and are killed.
However, in the process of boiling water to cool down, the temperature is just right for microorganisms and bacteria to multiply, and the longer it takes time, the more it will multiply, just like a basin of water outside, it will deteriorate after a long time.
How long it will take to spoil and it will not be suitable for drinking, in fact, there is no fixed time, because it is also affected by the objective environment. For example, in summer, the temperature exceeds 30 degrees Celsius, the air humidity is high, and the bacteria multiply quickly, which is very easy to be contaminated and cause diarrhea.
Therefore, it is best not to drink overnight water in summer, and it is best to put overnight water in winter in a covered cup, and then mix boiling water with warm water the next morning.

Don't drink boiled water overnight for several days, it's easy to have nitrite for too many days.

1.Formulation of the question.
In life, there is often a lot of water that needs to be boiled, such as cooking rice, drinking tea, and so on. Sometimes, because you are too busy or too tired, you forget to put the boiling water, and you don't find out until after a while. So at this time, can you still drink boiled water the next day?
2.Interpretation of the answer.
Whether boiled water can be drunk the next day, the old answer is simple: don't drink it. This is due to the fact that after a period of time or repentance of the boiled water, the microorganisms inside will gradually multiply, resulting in a change in the quality of the water.
In addition, there may be harmful substances such as bacteria and chemicals in the boiled water, which will be gradually released after long-term storage, further polluting the water quality.
3.What to do with boiled water.
Since you can't drink it, what should you do with boiled water? First of all, you can leave it for a while, wait for the water temperature to drop completely, and then pour out the water inside. The second way is to use it for cleaning purposes such as washing your face, washing your hands, and washing your clothes.
However, before use, it is best to boil the water again to kill harmful substances and ensure safe use.
4.Precautions for boiling water.
In order to avoid the situation that the boiled water cannot be used, we also need to pay attention to the following points when boiling water. First of all, do not use unclean kettles or cups to boil water, as the impurities in it will be released after boiling, which will have adverse health effects. Secondly, pay attention to the heat when boiling water, so as not to scorch the water or cause safety hazards.
Finally, after boiling water, it must be used or treated in time, and try to avoid long-term storage, which will cause water pollution.
5.Health requirements for drinking water.
We all know that more than 70% of the human body is made up of water, and drinking water plays a vital role in health. In order to ensure the safety of water quality, we need to pay attention to the following points. First of all, choose a water source with quality assurance, such as purified water or drinking water, and avoid drinking untreated tap water or well water.
Secondly, when drinking water, you should pay attention to the temperature, too hot water will damage the oral tissue, and by affecting the work of the digestive system, the body will be in a sub-healthy state for a long time. Finally, make sure that you drink enough water, but not too much, so as not to burden your body.
6.Summary. Although boiled water has been left out for too long to be consumed, it can be effectively avoided by implementing the correct treatment method or by using it as cleaning water.
In order to ensure the safety of drinking water, we also need to pay attention to the selection of water sources with guaranteed quality, and control the reasonable range of drinking water temperature and quantity. Only in this way can we provide a strong guarantee for good health.

-
You can drink it, and as long as the overnight water is stored well and is not contaminated by dust, bacteria, etc., it is safe to drink.
Nitrite in water is converted from the original nitrate in the water. In qualified drinking water, the content of nitrate is very low, and under normal circumstances, the amount converted into nitrite will be very small, and a small amount of nitrite will not be poisoning. Poisoning can only be caused when the intake reaches grams, and one or two glasses of overnight water are not enough to reach the dose of poisoning at all.
-
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 most feared carcinogen, 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, and carcinogens will not be born out of thin air in the case of replanting.
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.
