Can you still drink boiled water repeatedly? Can you drink boiled water repeatedly

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

Repeatedly boiled water can be drunk, and the molecules in the water will not be destroyed, so there is no harm to the body. Only when the water is repeatedly boiled about a few hundred times, the water will produce harmful substances to the human body, and this kind of water is not recommended for long-term drinking. Generally, drinking water at home will not be boiled so many times, so there is no need to worry.

Boiling water should not be boiled repeatedly, and nitrite will be produced, which is a carcinogen, so for the sake of your health, do not boil water repeatedly. But boiling water at a DAO fixed temperature without letting it boil is fine.

Health News] Do not drink boiled water that has been boiled repeatedly.

In fact, most people probably have the same experience, when you are cooking noodles or soup, when you are almost ready, only to find that the soup is too little, or the soup is too salty, you will pour hot water into it to achieve enough water or dilute the saltiness of the soup.

Secondly, when brewing milk or instant noodles, take the warm water directly from the thermos and boil it before brewing. This approach seems to be economically viable, saving time spent on cooking, as well as saving gas and water.

However, according to experimental proofs, if the water is boiled repeatedly, the nitrate in the water will be converted into nitrite, and nitrite will make the hemoglobin in the human body turn into nitrite hemoglobin, which will make the red blood cells lose the function of carrying oxygen.

Therefore, if you drink water that is boiled repeatedly, it may cause tissue hypoxia, shortness of breath, chest dullness, purple lips and nails, or easy sleepiness. If it is more severe, nitrite enters the body and is likely to be converted into carcinogens nitrosamines after the action of stomach acid.

In view of this, it is important to remember that when you drink this repetitive boiling water, it will have a negative impact on your health. For the sake of your health, don't be too gas-saving or too lazy.

I can drink it. Generally speaking, the reason for the increase of nitrite caused by repeated heating of drinking water is mainly the increase of nitrite concentration due to water evaporation and concentration, but the total amount does not increase; Another possibility is that some nitrates are heatedly broken down into nitrites. China's sanitary standards for bottled water stipulate that the nitrite content in water shall not exceed 2 micrograms per liter.

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

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?

Repeatedly boiled water is generally drinkable.

Repeatedly boiled water is drinkable and generally does not affect the body, but if the water is not stored in an improper environment, resulting in the growth of bacteria, this kind of water should not be drunk as much as possible.

According to the relevant national regulations, the nitrite content in drinking water should not exceed 1mg l is safe, and the nitrite exceeds the standard in repeatedly boiled water, which will not affect the body, so do not be too nervous. However, the boiled water should be placed in a hygienic environment, so as not to be improperly placed, which will lead to the growth of bacteria in it, which will have a certain impact on health.

The correct way to boil water

1. Because tap water has a chlorine smell after chlorine disinfection, when boiling water in a kettle, the lid should be opened when the water is about to boil (80-90 degrees Celsius), and then boil for 1-2 minutes after the water boils, and then turn off the heat. If you can't get the right amount of time when the water is about to boil, open the lid as soon as the water is boiling, and then wait 1-2 minutes before turning off the heat.

2. We usually boil water, just to kill the microorganisms in the water, boiling the water is the best sterilization method. However, the excrement of microorganisms in the water cannot be killed at 100, so the water should be boiled for 5 minutes before turning off the fire.

3. Water cannot be boiled repeatedly, it is best to drink it now. Repeatedly boiled water is "boiling water", and if the water is stored for too long, it will be polluted by the outside world, and the water is easy to age overnight to form stagnant water.

Boiling water repeatedly is drinkable.

Repeatedly boiled water is also called "boiling water", and people need to drink at least 20 tons of "boiling water" at a time to cause nitrite poisoning. So there will be no problem with the "thousand boiling water" that you usually drink.

And like the water heated by the water dispenser, the maximum temperature that can generally be reached is 90, so it will not boil, so there is no such thing as "a thousand boiling water", and repeated heating of the water stored in the inner tank for a long time will not have a fundamental impact on the water quality, but the mineral elements in the water may be reduced or lost.

So that's why water can't be boiled repeatedly.
