You can drink it. Under normal circumstances, the water can be heated after it is cool, and it will not have a great impact on human health, but if the water is stored for too long, more than a day, the water will breed bacteria and other harmful substances, and it is easy to accumulate toxins in the body, so it is generally not recommended to drink after secondary heating.

Note: Water can be drunk by reheating, but do not reheat it repeatedly.

5 The efficacy and function of boiled water.

Hydrate. Water in the human body accounts for 65-70%, is an important part of the human body, drinking boiled water can replenish the body's water, so that people's mental state is improved.

Laxative. Boiled water can promote the body's metabolism, help the digestion and absorption of food, thereby moistening the intestines and laxative, and relieving the symptoms of constipation.

Relieves fatigue. The lactic acid content in the muscles is one of the main factors of human fatigue, and drinking plain water can help the decomposition of lactic acid in the muscles, so that the fatigue of the body is relieved, and it plays a role in eliminating fatigue and maintaining the spirit and refreshment.

How long can you not drink cold boiled water, it is generally recommended not to drink boiled water for more than six hours, and store it at room temperature. Generally, if it is left for more than six hours, it is not recommended to drink it, because the water has been polluted for a long time when the boiled water is in contact with the air, and the content of subtin will also increase, which will have an impact on your health if you drink it.

It is recommended to drink as much boiled water as possible of the day, which can also boost metabolism.

If you put boiled water in other thermos cups, kettles, etc., the general storage time should not exceed one day.

Plain water should not be left for more than three days. If boiled water is left for 3 days, it will produce nitrous acid, which can make people dizzy, nausea and vomiting after drinking. If it is stored for a longer time and combined with amines, it will become nitrite amine, which can easily cause stomach cancer, liver cancer, and esophageal cancer.

You can't drink water overnight, and it's okay during the day.

If there is pollution, it is not recommended to drink cool boiled water no matter how long it is placed; On the premise that the water is not polluted and has no peculiar smell, it is not recommended to drink cool boiled water for 3 days.

In the process of placing hot water to become cool, there may be bacteria breeding, especially in summer, the temperature is relatively high, bacteria and other microorganisms multiply faster, if it is placed for too long, the cool boiled water may deteriorate, and drinking it when there are more bacteria may damage human health, if it is a water cup without a lid, dust and other substances in the air may also fall into the water cup. Some people with gastrointestinal diseases or sensitive stomachs, such as children and the elderly, are prone to abdominal pain, diarrhea and other symptoms after drinking water that has been left for too long. If you want to drink cool boiled water overnight, it is recommended to close the lid of the cup to avoid water pollution.

It is not recommended to drink cold boiled water for more than 3 days. Because the water will produce nitrite after being heated and cooled, and the amine will react to form nitrite, which is not conducive to human health, and the longer it is placed, the more the content, if it is drunk is harmful to human health.

In general, most people think that overnight water is not drinkable, but in fact, the nitrite content of cold boiled water does not change significantly between 24 hours, and it is usually drinkable normally. However, if there is an odor or contamination with foreign matter, it is not recommended to drink it.

Cool boiled water is easy to breed bacteria if left for too long, try to drink it within two days, and at the same time, the kettle should also be cleaned on time to prevent the accumulation of scale.

1. After the water is boiled at high temperature, it can kill harmful substances such as bacteria and microorganisms in the tap water, and under normal circumstances, drinking such boiled water is harmless to human health. Although the cold boiled water has been sterilized at high temperature, due to the limitations of the environment and storage methods, the bacteria in the air come into contact with the water for a long time, and it is easy to breed harmful bacteria to people, so the cold boiled water can not be drunk for a long time.

2. Cool boiled water will deteriorate for a long time and is no longer suitable for drinking, in fact, there is no fixed time, because whether cold boiled water can be largely limited by the influence of the objective environment. If it is in a general home environment, cool boiled water can be stored in a clean and closed container for about 3 days at most, and the water for more than 3 days will basically be contaminated and cannot be drunk.

3. In summer, it is best not to drink cold boiled water overnight, because the temperature is high in summer, the air humidity is high, the water environment itself is very suitable for the growth and reproduction of bacteria, and the family storage conditions are poor, so from a health point of view, it is better not to drink the cool boiled water overnight.

4. The cold boiled water that has not been drunk can not be heated and drunk again, especially the "back to the pot water" that has been boiled many times is not suitable for drinking, because some trace components contained in these boiled water after repeated boiling are increased, especially the nitrite solution increases. Drinking this water has a potential chronic harm to health.

It is not recommended to drink cold boiled water for more than 3 days. Because the sparrow will produce nitrite after being heated and cooled, and the amine will react to form nitrite, which is not conducive to human health, and the longer it is placed, the more the content, if it is drunk is harmful to human health.

Under normal circumstances, most people think that overnight water is not drinkable, but in fact, the nitrite content in cold boiled water does not change significantly for 24 hours, and it is usually drinkable normally. However, if there is an odor or contamination with foreign matter, it is not recommended to drink it.

Cool boiled water is easy to breed bacteria if left for too long, try to drink it within two days of burial, and at the same time, the kettle should also be cleaned on time to prevent the accumulation of scale.

It is not recommended to drink cold water after three days or more. If you leave it for too long, it may breed more bacteria, and it is no problem to drink a small amount, if you drink such water for a long time, it is not good for the human body, and it is not recommended to drink it again. It is advisable to drink fresh, boiled water and not water that has been left out for too long.

The shelf life of boiled water in the air is only 16 hours, and once the shelf life is exceeded, the E. coli contained in the water will exceed the standard and be destroyed.

Because when boiled water is placed in the air, the water surface will be contaminated and invaded by the bacteria flowing in the air.

The cool white old shed is boiled for 30 hours and cannot be drunk. The humidity in the air is relatively high, the bacteria multiply faster, the inactive boiled water is easy to cause pollution overnight, and the longer it is placed, the nitrite in the water will be higher, and drinking this water will affect the body, so it can not be drunk after 30 hours of cool white. <

Cool boiled water can be drunk for 30 hours. The humidity in the air is relatively high, the bacteria multiply relatively quickly, the inactive boiled water is easy to cause pollution overnight, and the longer it is placed, the nitrite in the water will be higher, drinking this water will affect the body, so it can not be drunk after 30 hours of cool white.
