The "carcinogenic water" named by the World Health Organization is not Thousand Boiling Water, Overnight Water, or Yin Yang Water. I advise you to stay away from it

After years of popular science, people have learned that long-term, large, and incorrect exposure to certain substances can cause cancer, such as consuming food contaminated with aflatoxin, which can lead to liver cancer, exposure to asbestos products, smoking, and so on.

Water, as an important substance second only to oxygen, requires our body to drink enough water every day to maintain normal operation and metabolism. The body often lacks water and may experience some abnormalities.

In the past, the folk belief that drinking Thousand Boiling Water, Overnight Water, and Yin Yang Water is prone to cancer was widely believed by many people. But using experimental means can verify truth and eliminate fallacies by finding the truth.

What is Thousand Boiling Water? Can it cause cancer?

Thousand boiling water is water that is repeatedly boiled in a container, containing purified water, tap water, well water, etc. Containers are commonly found in materials such as stainless steel, iron, ceramics, and water dispensers. The basis of the statement "Thousands of boiling water causes cancer" is that the water contains nitrate, which will be converted into nitrite after repeated boiling in the container, which is the basic substance of a carcinogen.

So, how much nitrite does the repeatedly boiled water contain? After multiple experiments by researchers, such as tap water, which contains 0.007 milligrams of nitrate per liter, it rises to 0.038 milligrams after boiling for more than 20 consecutive times and is maintained at this concentration for a long time during subsequent boiling. It does not exceed the national safety standard of 1 milligram per liter, so there is no need to worry.

What is overnight water? Can it cause cancer?

Overnight water is stored in a container for a long time after boiling, such as the water boiled the night before and consumed the next day. There is news that "overnight water contains more nitrite and bacteria grow", which has been tested and is also untrue. On the one hand, nitrite did not exceed the standard, and on the other hand, even after 48 hours of storage, there was no growth of a large number of pathogenic bacteria.

What is Yin Yang Water? Can it cause cancer?

Yin Yang water is a mixture of hot water and cold water that can be consumed in varying proportions. It is mainly used to quickly reach warm water without being too hot or too cold. Experiments have shown that if hot water is mixed with cold water, there is no problem. If hot water is mixed with unboiled water, as well as raw water such as tap water and well water, microorganisms may exceed the standard, which may cause diarrhea, but it is not considered carcinogenic.

The above three types of water actually contain nitrite, which is not excessive and very rare.

Nitrite carcinogenesis refers to food passing through the stomach, which contains gastric acid. Nitrite produces nitrous acid under the action of gastric acid, and then decomposes into nitroso. Nitroso and protein products in the body synthesize nitrosamines, which is a carcinogen and has a promoting effect on gastric cancer. But due to the extremely low content of nitrate in water, the nitrosamines formed are far from enough to cause cancer, so there is no need to worry.

The authoritative "carcinogenic water" announced by the World Health Organization is water that has a long-term drinking temperature exceeding 65 degrees Celsius. This water is a Class 2A carcinogen. There is sufficient evidence of carcinogenesis through animal experiments, and it may also cause cancer to humans.

Why can long-term consumption of hot water above 65 degrees Celsius cause cancer?

Water above this temperature can cause discomfort in the mouth, throat, esophagus, and other parts of the body, such as hot water, tea, and hot drinks that are already steaming and hot to the touch. Prolonged exposure to this can lead to cancer. Is the nitrite content inside particularly high? It's not that, we need to start with how cancer cells appear.

Cancer is the development of cancer cells over a considerable period of time, and cancer cells are mutated cells caused by normal cell replication and division errors in the human body. Normal cell division and replication are originally controlled by DNA, and everyone follows the rules. However, if certain parts of the human body are repeatedly damaged or inflamed, and normal cells repeatedly repair them, the probability of making mistakes during the division and replication process is high.

Water is an essential substance in our daily life. If it is too hot, it can cause frequent redness, swelling, and damage to the esophagus, oral cavity, and other areas. It is inevitable that cells will make mistakes during the recovery process, leading to the emergence of mutated cells called "precancerous cells".

After the appearance of precancerous cells, if they can evade the clearance of the immune system, they will gradually become cancer cells and grow up. After several years or even longer, they will develop into lumps and tumors, posing a threat to people's health. This is why hot water at 65 degrees Celsius can easily cause cancer. If someone drinks too hot water, hot tea, or hot drinks for a long time, they should pay attention.

Moreover, water is linked to food, and too hot food can not be eaten frequently. For example, fresh ingredients, Spicy Hot Pot, fresh soup, etc. when eating hot pot, it seems that there is a tingling sensation in the mouth and esophagus, but it is actually a warning and plea, indicating that mucosa may be damaged and inflamed.

In real life, drinking more hot water has become a way of maintaining health, but the degree of heat varies among individuals. Some people even have a certain tolerance due to long-term consumption of overheated water.

From a doctor's perspective, warm water below 50 degrees is acceptable because the tolerance of the oral and esophageal mucosa is 50 degrees. Not too hot, but also warm.

In addition, due to the importance of water to the human body, it is important to cultivate habits such as actively drinking water, drinking safe water, drinking boiled water, and avoiding drinking raw water. Do not wait until you are thirsty to find water. After getting up, drink a glass of warm water in a timely manner, and replenish water appropriately before going to bed. Drink no less than 1500 milliliters of water per day for adults.
