What types of water should not be drunk? Which water can not be drunk

Raw water. Bacteria, viruses and parasites that are harmful to the human body are found in raw water. Drinking raw water can easily lead to viral hepatitis, acute gastroenteritis, dysentery, typhoid fever and parasitic infections.

In particular, reservoirs, wells, and rivers are polluted by domestic wastewater, factory waste liquid and pesticides to varying degrees, and drinking raw water is more likely to lead to diseases.

Aged water. It is water that has been stored for a long time without moving, commonly known as "stagnant water". For minors, drinking this water often will significantly slow down the metabolism of cells and affect the growth and development of the body; For middle-aged and elderly people, it will accelerate aging.

In addition, the incidence of esophageal cancer and stomach cancer is increasing in many places, and studies have shown that it may be related to long-term consumption of aging water. Relevant data show that the number of toxic substances in aged water increases with the increase of water storage time.

A thousand boiling waters. Water that has been boiled repeatedly is called boiling water. Because it has been boiled for too long, the content of heavy metals such as calcium, magnesium and nitrite and other non-volatile substances in this water is very high.

Nitrite can also cause hypoxia and even coma, convulsions, and even death.

Steamer water. The leftover pot water for steaming steamed buns and steamed buns is steamer water, especially the steamer water that has been used repeatedly and repeatedly, and the concentration of nitrite is very high. Cooking porridge or drinking this water often can lead to nitrite poisoning.

In addition, the scale in the steamer water often enters the human body with the water, which will lead to lesions of the nervous, digestive, hematopoietic, urinary, circulatory and other systems and cause premature aging of the human body. This is due to the fact that the limescale contains more harmful elements such as cadmium, mercury, arsenic, and aluminum.

Do not boil the water. Most people drink tap water that has been chlorinated and sterilized. 13 harmful substances can also be separated from the chlorine-treated water, including halogenated hydrocarbons and chloroform with carcinogenic and teratogenic effects.

When the water temperature reaches 90, the halogenated hydrocarbon content will exceed the national drinking water hygiene standard by more than twice the national drinking water hygiene standard, from the original 53 micrograms per kilogram to 177 micrograms. Studies have shown that drinking water that has not been boiled increases the likelihood of developing bladder and rectal cancer21 38. When the water temperature reaches 100, these two harmful substances will be greatly reduced as the water evaporates, and if it continues to boil for 3 minutes, it will be safer to drink.

Re-boil the water. It is the habit of some people to re-boil the remaining warm boiled water in the thermos before drinking, in order to save water, coal (gas) and time. But this "savings" are not justified.

Because the water is boiled and boiled, the water will evaporate repeatedly, which will increase the nitrite content, and drinking this water often will accumulate nitrite in the body, resulting in poisoning.

1. Bladder cancer and rectal cancer with unboiled water Experts point out that drinking unboiled water increases the likelihood of bladder cancer and rectal cancer21 -38. When the water temperature reaches 100 degrees Celsius, these two harmful substances will be greatly reduced with the evaporation of the vapor, and if it continues to boil for 3 minutes, it is safe to drink. 2. Diarrhea, bloating, coma and convulsions are water that has been boiled on the stove overnight or for a long time, as well as water that has been repeatedly boiled in an electric water heater.

This kind of water is boiled for too long, and the water has a high content of non-volatile substances, such as calcium, magnesium and other heavy metal components and nitrite. Drinking this water for a long time will interfere with people's gastrointestinal function, causing temporary diarrhea and bloating; Toxic nitrite can also cause hypoxia in the body, and in severe cases, coma, convulsions, and even death. 3. Premature aging and cancer of steamer water Steamer water is leftover pot water such as steamed steamed buns, and the nitrite concentration of steamer water used repeatedly is very high.

Drinking this water, or boiling porridge with this water, can cause nitrite poisoning; Gutters often enter the human body with water, and can also cause diseases of the digestive, mental, urinary and hematopoietic systems, and even cause premature aging and trapped lead pure cancer. The following sleep can not be drunk, 1, unboiled water - bladder cancer, rectal cancer, 2, thousands of boiling water - diarrhea, bloating, coma and convulsions, this water is boiled for too long, the water is not volatile substances, such as calcium, magnesium and other heavy air metal components and nitrite content is very high. 3. Re-boiled water - poisoning, because the water is boiled and burned, so that the water evaporates again, the nitrite will rise, often drink this kind of water, nitrite will accumulate in the body, causing poisoning.

4. Steamer water - premature aging and cancer can cause diseases of the digestive, nervous, urinary and hematopoietic systems, and even premature aging and cancer.

Water is the essential source of our life, why do we say that? We can say that we will not eat for several days, but we should never go without water, and sometimes we may substitute drinks instead, but the drinks are also made of water. So, what kind of water is generally suitable for us to drink?

What kinds of water are not suitable for us to drink?

Aged water.

That is, stagnant water, which refers to the long-term storage of untouched water. For adolescents who are still in the process of growth and development, drinking stagnant water often will slow down the basal metabolism of somatic cells and immediately harm growth and development; Long-term use of stagnant water in middle-aged and elderly people will accelerate the aging of the body and increase the prevalence of rectal cancer and esophageal cancer. Since stagnant water is rich in many toxic substances, the longer it is stored, the more toxic substances it has.

Steamer water.

It refers to the water left over after steaming the ingredients. Tomato doctors suggest that because they are often used, they contain high nitrite concentrations, and if the average person drinks this kind of water regularly, it is very easy to cause nitrate poisoning. In addition, dirt can also cause several diseases of the nervous system, hematopoietic function, digestion and absorption, urinary **, etc.

A thousand boiling waters.

Drink less and not at all if possible. Due to the fact that after long-term boiling, the non-evaporating components magnesium, calcium and other heavy metals exceed the standard, and the nitrite becomes a high spine, often drinking this kind of water will harm the gastrointestinal effect, and the main manifestations of transient diarrhea and bloating will occur. At the same time, nitrite can also cause insufficient oxygen in the human body, which can lead to syncope and even death in severe cases.

Unboiled water

The temperature should be 100 so that the harmful substances will basically decrease with water vapor. If you drink unboiled water for a long time, the risk of stomach cancer and prostate cancer will increase.

For what is said today, everyone has different opinions and ideas, you can leave a message to discuss together, looking forward to your reply! If you like this article, don't forget to help like, comment, ** and favorite.

Aged water, unboiled water, boiling water, and steamer water should not be drunk directly. There are many microorganisms, toxic and harmful substances in aging Qingxiao water and unboiled water, which need to be strictly disinfected before drinking, and the nitrite content is very high after repeated use, and direct drinking will lead to nitrite poisoning. Reputation is cautious.

Repeatedly boiled water, water with a loss for a long time, stupid orange god water, steamer water, over-boiled water, these waters are not allowed to be drunk directly, otherwise it will affect the health of the body.

The water that cannot be drunk directly is the water that has been picked up from the tap, the water that has not been heated and sold in the state, the water that has been left out for more than one night, and the water that has been used to make tea.

Some water should never be drunk, otherwise it will bring disadvantages or even losses to health.

Listed on the "blacklist" are:

It refers to the stagnant water that has not flowed for a long time and the water that has been stored for too long, and the toxic substances increase with the extension of storage time. Taking nitrite as an example, water that originally did not contain this substance was stored at room temperature for only 1 day, and milligrams of nitrite were produced per liter of water, which rose to milligrams after 3 days of storage, and up to milligrams after 20 days. Nitrite can be converted into carcinogens nitrosamines under certain conditions.

The hardness of water refers to the amount of minerals dissolved in the water, and the more mineral elements such as calcium and magnesium in the water, the greater the hardness of the water. Drinking too hard water will affect the digestion and absorption of the digestive tract, causing indigestion and even diarrhea. Long-term drinking of this kind of water can also induce stone disease in internal organs, such as urinary stones, gallstones, etc.

However, as long as the water is boiled and cooled, most of the minerals will settle down, and the hardness will become smaller, and it can be drunk.

Such as distilled water, because there are too few or even no mineral elements in the water. Long-term consumption of soft water is associated with increased morbidity and mortality from cardiovascular diseases.

River water, stream water, well water, and reservoir water contain a variety of bacteria, viruses, and other microorganisms, as well as zoonotic parasites. Once drunk, people are prone to acute gastroenteritis, hepatitis, typhoid, dysentery and parasitic infections. Especially now, large and small rivers, reservoirs, and well water are polluted by the "three wastes" of factories, domestic wastewater and pesticides to varying degrees, and drinking raw water is more likely to be harmed.

Refers to water that has been boiled overnight or for a long time on a stove fire, including water that has been boiled repeatedly in an electric water boiler and water from a steamer. Non-volatile substances such as calcium, magnesium and nitrite in this kind of water are increased, and regular drinking is harmful to health.

Raw water is not drinkable, and unboiled water is not drinkable. Because the tap water is chlorinated and disinfected, the chlorine-treated water can separate more than 10 kinds of harmful substances, among which halogenated hydrocarbons, chloroform, etc. also have carcinogenic and teratogenic effects. When the water temperature is heated to 90, the content of halogenated hydrocarbons and chloroform exceeds the national drinking water standard by more than 2 times.

Drinking this water regularly increases the likelihood of bladder cancer and rectal cancer by 20 to 38%. Once the water temperature reaches 100, the harmful substances will be greatly reduced with the evaporation of the steam, and it will be safer to drink if it continues to boil for 3 minutes.

Some people have the habit of boiling the remaining warm water in the thermos before drinking, which seems to be a frugal approach. The water boils and burns, and the water evaporates again, and the nitrite concentration rises. Drinking this water is equivalent to drinking a large amount of nitrite, and the consequences are self-evident.

There are many types of water that cannot be drunk: steamer water, heavy water, and sewage cannot be drunk. And also:

Salary, molten steel, ink, red potion, purple potion, flower water, squirt water, aqua regia, banana water (acetone), Tianna water, water in painting, water on **, water in sculpture, Hengshui (Hebei Province), Lianshui (Jiangsu Province), Lishui (Zhejiang Province), Tianshui (Gansu Province).

If you melt the metal into water, you can't drink it.

What kind of water should not be drunk? Star Awareness Project

(1) Senkai water and steamer water are harmful to the body "Senkai water" is boiling water that has been boiling on the stove for a long time, and water that has been repeatedly boiled in an electric water heater while drinking tea. Because the boiling time is too long, the water contains no volatile substances, such as calcium, magnesium and other metal components and nitrite content. Toxic nitrite can also cause hypoxia in the body, and in severe cases, coma and even death.

In addition, after repeated boiling of water, minerals that are easily absorbed by the human body are turned into precipitated particles that are difficult to be absorbed by the human body, and the nutritional value of the water is lost. (2) Aging water can not be drunk The longer the storage period of aging water and stagnant water, the more toxic it is, which will significantly reduce the cell metabolism of minors and affect their growth and development. It accelerates aging in middle-aged and elderly people, and the incidence of cancer is high.

3) Too hard water is not drinkable The hardness of water refers to the amount of minerals dissolved in the water. The greater the content of minerals such as calcium and magnesium in the water, the harder the water will be. Drinking water with excellent quality will affect the digestion and absorption function of the gastrointestinal tract, causing indigestion or diarrhea.

Long-term drinking can increase the incidence of stones in the internal organs. (4) Medical water should not be used as drinking water At present, some drinking water called "electrolyzed water" and "oxygen-rich water" on the market, strictly speaking, these are medical water, which cannot be used as drinking water for normal people, nor should it be used as drinking water for domestic drinking water. (5) Distilled water is not recommended to drink Distilled water is soft water with too little mineral content or no minerals.

6) Pure water is not recommended to drink Experts believe that the biggest disadvantage of pure water is that it removes calcium, magnesium, fluorine, iodine, selenium and other minerals and trace elements necessary for the human body. According to some data, the intake of calcium and magnesium in drinking water should account for 5%-20% of the total intake, and the lack of this part of the intake may affect the normal parenting of adolescents.

Purified water has a strong ability to dissolve various trace elements, compounds, nutrients, after drinking a large amount, some of the body's essential (7) Pure water is acid water The biggest problem of pure water is that not drinking it for a long time will lead to malnutrition, decreased immunity, so that people have general weakness, prostration, long-term drinking of pure water will affect the absorption and utilization of nutrients and deposition in the body, and accelerate the loss of nutrients. (8) Undrinkable raw water River water, stream water, well water, reservoir water, and tap water contain a variety of bacteria, microorganisms, and zoonotic parasites that are harmful to the human body. Drinking this raw water can easily cause acute gastroenteritis, viral hepatitis, typhoid, dysentery and parasitic infections.

9) Repeated heating of bottled water can cause cancer (10) Beverages are not equal to drinking water, and beverages cause chronic benzene poisoning when drunk (11) "Antimony" in bottled mineral water may be harmful to health Plastic bottles may continue to dissolve chemical elements into mineral water" (12) Health killer faucet The tap water in the faucet and nearby water pipes that have been deactivated overnight is stationary, and the residual microorganisms in the water will multiply. Therefore, it should not be consumed.
