The operation of all life is inseparable from the word water, which also makes water called the "source of life".
With the improvement of people's living standards, people pay more and more attention to the safety of diet, and the demand for safe drinking water is also increasing. Especially after the discharge of nuclear wastewater in Japan, there is a growing concern about water.
In addition to the cool white water and mineral water commonly used in our lives, there are many rumors about water on the Internet, the most common of which is the news that thousands of boiling water and overnight water cannot be drunk.
It has been said that boiling water and overnight water contain nitrites, which greatly increases the risk of cancer when consumed.
But in fact, a professional Chinese medicine practitioner responded to this statement, saying that it is just a rumor that thousands of boiling water and overnight water cause cancer. There is a type of water that increases the risk of cancer until it is consumed.
So what exactly is this water, how can we ensure healthy drinking water in our daily life, and what are some other tips for drinking water?
1. Is boiling water and overnight water carcinogenic?
There is a lot of news on the Internet that you must not drink boiling water and overnight water, thinking that these two kinds of water will produce nitrates and nitrites, which greatly increase the risk of cancer.
The so-called boiling water is the water produced by boiling the water repeatedly. As the name suggests, overnight water is the water that has not been drunk on the day and has been left overnight.
Nitrate and nitrite are internationally rated as Class 2A carcinogens, and it is precisely because of the fear of cancer that many people believe in the rumor that these two types of water cannot be drunk.
But in fact, this is just a rumor, and drinking these two types of water does not increase the probability of cancer, and even has no health effects.
The main reason why people are concerned about boiling water is that the nitrite contained in it will be oxidized into nitrate during the repeated boiling process.
However, studies have proved that even if the water is boiled many times, the nitrite and nitrate content in it is far below the national standard limit for drinking water, so it does not increase the risk of cancer.
In addition to boiling water, overnight water is also not a health hazard. Many people think that boiling water can remove a lot of bacteria, but if the water is left overnight, a lot of microorganisms will be produced.
It is believed that if you drink it for a long time, it will cause harm to the body and even cause cancer.
But in reality, as long as the container is clean and airtight, the chances of microbial invasion are very small. Even overnight water that is at room temperature and unsealed is boiled to reduce the nutrients in the water and make it difficult for microorganisms to survive in it.
Therefore, even if the boiled water is left for one day, two days, or even three days, microorganisms will not be detected.
From this, it can be concluded that whether it is a thousand boiling water or overnight water, as long as it is under normal circumstances, it does not increase the risk of cancer.
If you eat overnight or in a hot meal, nitrates and nitrites may be present, which can affect our health.
However, not all water is safe to drink, and some types of water may increase the risk of cancer.
Second, it is this water that is really carcinogenic!
Water that really causes cancer is a hot drink above 65 degrees. Many people like to eat duck intestines very much when eating hot pot, and although our esophagus is thicker than duck intestines, the situation after drinking hot water is actually very similar to the scalded duck intestines.
If the temperature of the water to be drunk exceeds 65 degrees, it will cause thermal damage to our esophagus, and the oral mucosa will also be damaged.
After damage to the esophageal and oral mucosa, the cells of the mucosal layer on the surface will be detached and regenerated.
If you drink hot water for a long time, this condition will recur, increasing the rate of cell proliferation, increasing the possibility of cell mutation, and greatly increasing the risk of cancer. Many esophageal cancer patients have the habit of eating hot things and drinking hot drinks.
The World Health Organization has conducted a study on the risk of esophageal cancer with hot drinks. Studies have shown that people who drink hot water between 65°C and 69°C for a long time are twice as likely to develop esophageal cancer as those who drink water below 65°C.
People who drink hot water above 70°C have eight times more than normal esophageal cancer, and this data can be used to find out the effect of water temperature on esophageal cancer.
Therefore, in order to prevent the occurrence of esophageal cancer, it is necessary to avoid drinking hot water and hot drinks higher than 65 degrees for a long time.
We can judge the temperature of hot drinks by the degree of ingestion, and hot water above 65 degrees Celsius will cause a hot stinging sensation when it touches the lips, so it is not suitable for drinking. When the water is cooled to a temperature that does not feel uncomfortable, it is a very suitable drinking temperature.
Therefore, we should never drink excessively hot drinks and water in our daily life. Although water above 65 degrees Celsius increases the risk of cancer, drinking it once in a while does not have much effect.
If you have the habit of drinking hot water and hot drinks for a long time, you must pay attention to it to avoid adding burden to your physical health.
However, drinking water is essential for good health, and a good way of drinking water may have a beneficial effect on our health. So how can we maintain a healthy way of drinking water in our daily lives?
3. How to drink water to be healthier?
Drinking water is an important factor in maintaining good health, and drinking the right water can help us remove toxins from the body and boost metabolism. Here are some scientific drinking tips that can help us maintain good health.
The first thing is to ensure a fixed amount of water intake. Normally, adult men should keep their daily water intake at more than 1,700 ml, which is equivalent to 3.4 bottles if calculated according to the 500 ml mineral water bottles on the market.
For adult women, it is more than 1500 ml, which is about 3 bottles of water. If you exercise a lot and the climate is hot, you can increase your water intake.
Never feel thirsty when drinking water. Thirst is a sign that the body is dehydrated, and the body is already in a state of dehydration.
It is advisable to drink water every one to two hours to maintain the balance of fluids in the body. However, it is important not to drink a lot of water at one time, as it may cause additional strain on the heart and kidneys.
Attention is also needed in terms of the type of drinking water. Scientific studies have shown that the freshest plain water is the most beneficial for good health.
Boiled water is produced by boiling natural water, which kills microorganisms in the water while retaining the minerals in the water that are beneficial to the human body. This not only ensures the health of the water quality, but also prevents aging.
The second is to ensure the right drinking temperature as we mentioned above. Generally speaking, the temperature of drinking water is 50°-60° is the best, when the human body drinks too cold water, it will cause the blood vessels in the mouth, esophagus and tail to shrink rapidly, thereby affecting the absorption of the digestive tract and the operation of nutrients, resulting in bloating and diarrhea.

Drinking too hot water can cause damage to the mouth, esophagus and stomach, and also increase the risk of disease.
When drinking water, we can touch the water glass with our hands, if the temperature is warm and comfortable, not hot, then the water temperature may be close to 50-60 degrees, if it is too hot, it is not suitable for drinking.
On weekdays, it should be noted that you should never drink a lot of water after exercise, and you must gradually replenish water after your body has recovered.
When you have a cold, you must also drink plenty of water to replenish the lack of water in your body. If you have stones, ventilation, or diabetes, you must drink water to reduce the symptoms caused by the disease.
However, on weekdays, we can also add some items to drinking water to make the body healthier.
Fourth, adding these to the water is good for the body
Adding goji berries to water is very beneficial to health. Goji berries have the effect of nourishing the liver and kidneys, lean and bright, and adding wolfberry to water on weekdays can enhance the body's immunity and play an antioxidant role in delaying aging.
The total flavonoids in roses can remove oxygen free radicals in the body, relieve stress, help sleep, and delay aging.
When you have a cold, you can add chrysanthemums, honeysuckle, honey and other items to the water. These foods have the effects of anti-inflammatory, heat clearing and detoxification, which can greatly reduce the symptoms of colds and speed up the recovery of colds when they catch a cold.
Lemon soaking water can not only make the water have a fragrant taste, but also the vitamin C contained in lemon can also effectively prevent myocardial infarction, lower blood pressure, and prevent kidney stones.
You can also soak mint in water after exercise, which can quickly quench your thirst and help your body flush out waste.
Hawthorn, forged, cassia seeds, notoginseng flowers, barley and other items soaked in water will have different benefits for physical health.
Not only does this increase the nutritional value and taste of the water, but it also provides additional benefits to the body. However, it is important not to replace medicine with additives in water, and if you have a medical condition, you must drink it under the guidance of a doctor.
epilogue
In general, there is no risk of carcinogenic water and overnight water, and we don't need to worry too much about this, as long as the water source is clean and clean, you can drink it normally.
However, we should never drink water above 65 degrees, this kind of water will not only not be beneficial to our health, but will greatly increase our risk of esophageal cancer and stomach cancer.
Drinking healthy water can not only avoid the occurrence of these cancers, but also reduce the probability of blood clots and cardiovascular and cerebrovascular diseases.
However, if we want to prevent diseases, we still need to go to the hospital for regular physical examinations, so that some malignant diseases like cancer can be strangled in the cradle and avoid the further development of the disease.
