Can I still drink boiled water overnight?

If the water cannot be drunk overnight, then it must be because the water has deteriorated and new substances have been formed. However, there is no fixed time point for the deterioration time of water, because the quality of water will be affected by objective environmental factors, such as the external temperature, the temperature is high in summer, and there is more moisture in the air, the bacteria will multiply quickly, and it is easy to spread and pollute the water source, so try not to drink the water overnight in summer. Moreover, experts also recommend that it is best not to leave boiled water for too long, and boiled water after many days is not suitable for drinking.

Of course you can drink it, it's cool and white! CCTV talk shows have said this problem before, and it is okay to drink.

Generally, it is best not to drink boiled water overnight, although sometimes you will feel nothing after drinking, but in fact, you must know that the original water is stored for too long, it will be infected by bacteria and produce nitrite, once nitrite enters the human body in large quantities, it can make tissues lack oxygen, nausea, vomiting, headache, palpitation and other symptoms, and in severe cases, it can also make people die of hypoxia.

Of course, I can drink it, I often drink a glass of cold boiled water when I get up in the morning, that is, I poured it the night before, and there is no discomfort in my drinking, because boiling water does not produce or increase the nitrite content because of storage. Nitrite is produced by the reduction of nitrate, but the premise of all this is that there needs to be enough nitrate in the first place; Secondly, there needs to be a reducing substance that converts nitrate into nitrite.

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. Therefore, it is best to drink boiled water on the same day.

There may be some microorganisms multiplying in the overnight water, but it does not have a great impact on people, as long as the water is not polluted, the water quality will not change, then there is no problem. It is recommended not to exceed 24 hours, more than 24 hours is easy to be detrimental to health.

Of course, the difference is that if it is in a kettle overnight, it is still hot water, suitable for all ages. If it's in a teacup overnight, it's cold water. The essence of its boiling water remains unchanged, but the water temperature changes, and people with a bad spleen and stomach should avoid drinking cold water.

It is recommended not to drink. This is because overnight coolness will combine with carbon dioxide in the air and deteriorate, in addition to nitrite, which can cause damage to the body's health. It is recommended not to drink again as well.

In fact, the statement that water cannot be drunk overnight is not true. We know that overnight tea cannot be drunk, mainly related to vitamin contamination. However, even if tap water is left for a day or two after boiling, the chance of contamination is very small, so it can be drunk with confidence.

Of course, it is a drinking habit for many people not to drink overnight water. However, two primary school students in Beijing proved through scientific experiments that water can be drunk overnight.

In the science and technology museum, they placed the hot water for one day, two days, three days and the water sample of tap water for comparative chemical analysis, respectively, and measured the pH value, phosphate, nitrate, dissolved oxygen, chlorine, chemical oxygen consumption and other values are within the normal range, that is, overnight water does not have any *** for the human body, and can be drunk.

The two elementary school students did this experiment because they secretly visited some institutions and found that an office of a certain institution made four thermos of boiling water every day, and the next morning they had to pour out more than one bottle. The agency has a total of 62 offices, and 38 tons of water are dumped in a year. How many offices there are in Beijing, and how many offices there are in the country, the amount of water wasted without overnight water alone is a staggering amount.

The two primary school students used science to tell people that water can be drunk overnight, and also put forward specific water-saving suggestions: first, we should be careful and make a careful calculation, drink as much water as we want; The second is to concentrate **, prepare some clean containers to gather the remaining water and then use it for other purposes; The third is to use an electric water heater, and you can drink as much as you want. It should be said that these suggestions are not difficult to achieve.

China is a water-scarce country, but on the other hand, there is a serious waste of water resources. Establishing a sense of water conservation, making effective use of limited water resources, and putting an end to all waste of water resources are major issues that have a direct bearing on the future survival and development of our nation. Shouldn't all the adults do better in the face of the "scientific" advice of two elementary school students?

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?

Yes, the microorganisms and bacteria inside are killed by high temperatures, and other bacteria will not grow overnight.

You can drink it, don't drink it if it's more than 48 hours

Life kisses me with pain, but I want to repay it with a song.
