Does the water in the kettle need to be changed every day? Can you drink water overnight

The water in the kettle does not need to be renewed every day, but the water that is more than three days old needs to be changed, and the water can be drunk overnight.

Although the thermos contained boiling water, after a few days of storage, the bacteria and microorganisms inside had regrown.

If the bottle is not well sealed, it will not only breed a large number of germs, but also dissolve impurities such as fine dust and soot in the air in the water, causing water pollution. Long-term consumption of boiled water is susceptible to infection by bacteria and other harmful substances, causing a variety of diseases.

If minors drink this water for a long time, it will reduce the body's metabolism, which will affect the growth and development of the body. Regular consumption of this drink in the elderly will accelerate aging and increase the risk of stomach and esophageal cancer.

As the name suggests, overnight water is water that has been left out overnight and drunk the next day. If you boil water in the morning, you can drink it in the afternoon, so if it is water that has just been boiled in the evening, it will not take more than 12 hours overnight, so it can also be drunk.

Some people think that overnight water contains a lot of nitrite.

But in fact, the formation of nitrite requires a specific environment and a specific substance to form nitrite, and both need to be met at the same time, and there is no substance that can produce nitrite in boiling water.

After boiling the water, most of the bacteria are killed, and even after one night, the bacteria will not multiply anymore because there is not so much nitrate in the water in the first place, and it will not produce too much nitrite overnight.

Therefore, it is nonsense to say that there is a large amount of nitrite in overnight water, and there is no scientific basis at all.

Water is purified water, boiled water and mineral water, and it has been found that boiled water is the best choice for human health, it can increase the bioactive enzymes in the human body and reduce lactic acid in the muscles.

Helps to eliminate fatigue and restore energy.

Try not to drink the overnight water of the thermos. The nitrite content in the overnight water will be given more, and long-term drinking will be bad for the body, so you should drink more warm water every day. Don't wait until you're too thirsty to rehydrate.

It is recommended to change the water in the kettle every day, and the water can be drunk overnight, but it will breed bacteria if it is left for a long time.

The water in the kettle does need to be replaced with new overnight water every day, but it is best not to drink it.

The water in the kettle should not be drunk again if it is left for three days.

Because it is left for too long, nitrite will be produced after the bacteria multiply in large quantities, and if the human body ingests too much nitrite, it will cause symptoms such as hypoxia and nausea, and it is easy to induce cancer, of course, the premise is that it is ingested in large quantities. If you accidentally drink it once in a while, it will not cause great harm, and the accumulation of toxins will affect the body. In addition, do not drink the water that has been boiled repeatedly, it also contains a lot of nitrite.

Cool boiled water should not be drunk for more than three days.

It cannot be consumed for more than three days. This is because if you sleep for too long, you can be contaminated by bacteria and produce a carcinogen --- nitrite, which is highly toxic to the human body. Once a large number of people enter the human body, the red blood cells in the blood can lose the role of carrying oxygen, resulting in tissue hypoxia, nausea, vomiting, headache, palpitation and other symptoms, and in severe cases, people can also die due to lack of oxygen.

Nitrite can combine with organic amines in the human body to form nitrosamines, which can promote esophageal cancer, liver cancer, stomach cancer, etc.

According to relevant data, the newly extracted deep well water contains only milligrams of nitrite per liter, but it will rise to milligrams after three days of storage at room temperature; Water that used to be nitrite-free, stored for one day, produced milligrams of nitrite per liter of water, rising to milligrams after three days and up to milligrams after 20 days.

The water in the water dispenser can be stored for 7 days, if it is more than 7 days, it needs to be boiled before drinking, otherwise it cannot be drunk directly

Many people think that overnight water cannot be drunk, and many people think that it can be drunk, but can it be drunk or not?

Overnight water in a thermos can be drunk;

It is best to drink it freshly or only the boiled water of the day. Also do not drink boiled water that has been boiled for too long, not for more than 24 hours. The nitrite content in boiled water is higher than that in raw water.

Moreover, the nitrite content of boiling water that has been boiled for too long or more than 24 hours has been boiled for many times. After 24 hours of boiling water, the nitrite content is twice that of the first boil. The re-boiling of drinking boiled water will cause the nitrite content in the water to exceed the standard, and the excessive and excessive nitrite in the water can cause physical fatigue, fatigue, drowsiness, coma, bruising, blood pressure dropping, abdominal pain, diarrhea, vomiting, and malignant diseases over time.

The way to prevent boiling water pollution is simple: resolutely put an end to the reuse of boiling water and re-boiling.

Five types of boiled water that you can't drink:

boiling water that has been boiled on the stove for a whole night or for a long time, and is already lukewarm when drunk;

boiled water in an automatic water heater that is reboiled overnight;

residual boiling water that has been boiled several times;

The water in the thermos is no longer the water of the day;

Leftover boiling water from steamed rice, meat, and other foods.
