Does water in a thermos pot have an expiration date? Can I drink it after two days?

The water in the thermos pot also has an expiration date, and you can't drink it after two days because there may be a lot of bacteria in it.

It has an expiration date, so you can drink it after two days. To ensure that the water quality is clean water, and it is boiled, it can still be drunk after two days in a thermos pot.

I don't think there's an expiration date. After two days, I can still drink it, but the taste will become bad.

It is best not to store plain water in a thermos for more than 24 hours.

It is best to drink the water in the kettle within one day, don't drink it the next day, the water is stored for too long, it will be infected by bacteria to produce nitrite, once nitrite enters the human body in large quantities, it will make the tissues hypoxic, nausea, vomiting, headache, palpitation and other symptoms, and in severe cases, it can also make people die of hypoxia.

If the inferior thermos cup may contain some heavy metals, although there are fewer heavy metals in the overnight water, there are still them, so try not to drink overnight water, generally not more than 24 hours.

Generally, boiled water can not be drunk after three days in a thermos flask, because if it is placed for too long, nitrite will be produced after a large number of bacteria multiply, and if the human body ingests too much nitrite, it will produce symptoms such as hypoxia and nausea, and it is easy to induce cancer, of course, the premise is a large amount of intake.

Nitrite can also form nitrosamines in the human body, promote liver cancer, stomach cancer, etc., after the boiling water in the thermos bottle becomes warm, the bacteria multiply faster, and the nitrite is reduced. Therefore, the water that has been left in the thermos for three days is not drinkable, and it is recommended to pour it out and re-boil the kettle.

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 an hour has been boiled for many times. After a few hours of boiling water, the nitrite content is the same as when it was first boiledFold.

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:

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

2.Boiling water that is reboiled overnight in an automatic water heater;

3.Residual boiling water that has been boiled many times;

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

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

A thermostatic kettle may have a capacity of more than 1 liter, which can support your baby to brew milk powder several times. Some babies are already eating complementary food or mixed feeding, and the frequency of brewing milk powder is not high, and the probability of using water in the thermostatic kettle is relatively low. The temperature of the water in the thermostatic kettle has been kept in a constant state, so how long can the water in the thermostatic kettle be kept and not drunk?

If the thermostatic kettle water is left for 24 hours, it should not be given to the baby again. Because the water in the thermostatic kettle is left for a long time, it is easy to produce bacteria, viruses, microorganisms, etc., which is not as healthy as fresh water. Therefore, if the water in the thermostatic kettle is not used for a long time, parents remember to replace it with new water for the baby to make milk powder, and do not use the water in the thermostatic kettle.

If parents accidentally use the water in the constant temperature kettle for a long time to brew milk powder, after a few days to observe whether the baby is uncomfortable, diarrhea and other problems, if there is no need to worry, but there are symptoms of diarrhea, then there is a guess that the water is caused by the use of a constant temperature kettle for a long time, and take the baby to the doctor to explain to the doctor.

In addition, although the thermostatic kettle is very easy to use, it is not recommended to give the baby the water in the thermostatic kettle often, because the water in the thermostatic kettle is heated repeatedly, which is very easy to produce nitrite.

and other harmful substances, but it brings great harm to the baby's body.

It is better not to drink.

Boiled water, because it is polluted by bacteria in the air, is certainly not as pure and hygienic as fresh boiled water, so it is best not to drink water that has been stored for too long, the longer it is stored, the more unhygienic it will be. Plain water will not cause cancer because it is stored for a few days, but it is possible to cause disease, so it is best to drink it when it is fresh.

"If the water is left for too long after boiling, it will also become aged water, and the toxic substances in the aged water will increase with the increase of water storage time. Therefore, it is best to drink the boiled water on the same day, and experiments have shown that drinking boiled water that is naturally cooled and left for no more than 6 hours is the most beneficial to human health."

So, it's best not to drink overnight water.

It's better not to drink it!There are bacteria.
