Can you still drink water after a few months, and can you still drink mineral water after a month?

The water that has been put for a few months can not be drunk, and the water that has been put for a long time will breed bacteria and be harmful to the body.

There are many factors that affect the "shelf life" of boiled water, such as whether the container is clean, the tightness of the container, the degree of heat preservation, and the level of room temperature.

Boiled water, that is, water that boils for 3 minutes, pours into a clean cup and cools to 25 30. Fresh boiled water is sterile, and the pathogenic microorganisms in it are killed during the boiling process. However, after the temperature of boiling water drops to room temperature, some microorganisms will multiply in the water, and the number of microorganisms will increase with time, so it is not recommended to continue drinking boiled water that has been left for too long.

If there is already an abnormal color or smell, it must be discarded in time and cannot be further drunk.

It is recommended that boiled water should be drunk in time and not stored for too long. If you drink boiled water that has been stored for too long and have uncomfortable symptoms, you should go to the hospital for medical treatment in time**.

If it is unopened and within the expiration date, it is best not to drink it, although it is water, he also has an expiration date.

If it is unopened mineral water, it is definitely drinkable if it is still within the expiration date.

Groundwater has been buried for so long, don't you drink it when you put it up, it depends on your storage conditions, bottled water has a one-year shelf life, not to mention that it only takes a few months to get water. I didn't feel at ease, so I boiled it and drank it.

It is not recommended to drink under extreme survival conditions!

No. The water in the water dispenser cannot be drunk after a month, because the water in the water dispenser has no fluidity in the water dispenser, and it is completely possible that bacteria will breed if it is placed in the water dispenser for a month. If you drink it in this case, there is a risk of gastrointestinal infection and inflammation, so it should be avoided.

Bottled water of good quality can also breed bacteria if left for a long time after opening, so it is recommended to use it within 7-10 days after opening. Especially in the hot summer, bacteria are easy to multiply quickly, so it should be drunk in time.

Precautions for the use of bottled water.

Generally speaking, the qualified bottled water barrel body has good transparency and smooth surface, while the transparency of inferior water barrels is generally poor, the color is mostly dark blue or purple, and the surface is rough, especially the rough and piercing hands at the bottle mouth.

It is best not to heat and drink bottled mineral water, because the calcium and magnesium in the heated water are easy to form scale with carbonate, which not only affects the taste, but also easily causes mineral deposition in the water dispenser, which affects the health of the body. Refrigerated water should also be drunk with caution, because the temperature of refrigerated water is generally 0-5, which is not enough to kill many bacteria.

Boiled water that has been left for a few days is certainly not as pure and hygienic as boiled fresh boiled water because it is contaminated by bacteria in the air, so it is best not to drink water that has been stored for too long, the longer it is placed, the more unhygienic it will be.

If the water quality is inherently acceptable and the nitrite content is low, then the nitrite that can be produced after boiling will also be very small. "Experts agree that plain water does not cause cancer because it is stored for a few days. However, it is possible to cause disease, so it is best to drink it fresh when it is fresh.

Benefits of plain water.

A glass of life-saving water before bedtime for heart disease. If you have a bad heart, you can get into the habit of drinking a glass of water before going to bed, which can prevent diseases like angina pectoris and myocardial infarction that tend to occur in the early hours of the morning. Diseases such as myocardial infarction are caused by the high viscosity of the blood.

When a person is asleep, due to sweating, the water in the body is lost, causing the water in the blood to decrease, and the viscosity of the blood will become very high. However, if you drink a glass of water before bedtime, you can reduce the viscosity of your blood and reduce the risk of heart attacks.

After boiling water, it is generally not recommended to drink it for more than 24 hours.

Some studies have found that the nitrite content in boiled water is higher than that of unboiled water, and the nitrite content is significantly increased in boiling water that has been boiled many times, boiled for too long, and placed for more than 24 hours, which is not conducive to human health. After 24 hours of boiling water, the nitrite content is twice that of freshly boiled water, and nitrite can form carcinogenic nitrosamines in the human body.

It is not drinkable. Plain water is also not drinkable.

Generally, mineral water has a shelf life, which is one year for bottles and one month for barrels. However, the mineral water after opening is not guaranteed by the above period and should be drunk as soon as possible. If you put boiled water for a long time, the bacterial indicators in it will change, and drinking this water often will significantly slow down cell metabolism and affect the growth and development of the body for minors; Middle-aged and elderly people will accelerate aging.

Can't drink it anymore. Mineral water can't be drunk after a month, because after you open the bottle, there will be air residue in the bottle, and the water will be polluted in time, so it is recommended that you do not drink it.

The shelf life of mineral water after opening is 15 days, so you can't drink it! If you put plain water in a bottle for 3 days, it is best not to drink it again.

You can't drink it, and other substances will be produced after a long time.

Bottled water is left for half a month depending on the situation, and bottled water is unopened, and it can be drunk for a month, and there will be no big problems. If the bottled water is opened, it is not suitable for drinking for one month, because the microbial indicators in it have exceeded the health standard, and it is not good for your own health after drinking.

Bottled water refers to the pure water or mineral water that is processed by modern industrial technology (reverse osmosis, electrodialysis, distillation, resin softening, etc.) by tap water or groundwater, and is filled to PC barrels by the filling production line. Bottled water is purified water, mineral water, and mineral water (made from purified water artificially added with minerals), among others.

No. Generally, it is susceptible to the influence of microorganisms after opening, especially after being left for a long time, there may be microbial nourishment. In order to prevent the growth of microorganisms in the water and cause diarrhea, it is best not to store the mineral water or open plain water for more than one day after opening.

Scientific studies have shown that overnight water contains chemicals such as zero alcohols, oxyphenols, hydroxyhydroxyls, hydrohydroxy acids, caustic hydrogen, and dizero ethers, and when you drink overnight water, these chemicals will enter the bloodstream and circulate to every corner of your body, affecting almost every physiological response. If too much is ingested at one time, it can cause stomach bloating, nausea, vomiting, and loss of appetite.

Purified water, once unsealed and in contact with the air, begins to grow bacteria after 24 hours. Not to mention it's been a month ! And pure water is harmful to the body

Purified water is relatively acidic water, with a pH value below it. Moreover, in the process of making pure water (distillation, membrane filtration or reverse osmosis, etc.), the large structure of water has been destroyed. The minerals and trace elements that make up water that are beneficial to the human body are completely destroyed, and only water in the form of water that has been degraded is left, and its function can only play a role in quenching thirst.

If you drink it for a long time, the cells in the body will become acidic, which is the source of all diseases. Once the constitution becomes acidic, the cell function will deteriorate, the role of various organs and tissues of the body will also be weakened, the metabolism will slow down, waste products will not be easy to discharge, and the burden on the kidneys and liver will increase, resulting in the formation of chronic diseases. For example:

Sub-health, diabetes, cancer and other diseases. In fact, in many countries, only hemodialysis patients drink purified water. Not to mention the production of unspecified purified water.

No, the so-called pure water is also chemically treated, so it also contains various substances, and a small number of microorganisms are not all able to treat light, but the content is much lower than that of untreated. However, if you leave it in a sealed condition for too long, microbial fermentation will produce a special odor in the absence of oxygen. Therefore, in general, pure water should not be left for too long.

It is better not to drink the bottle after opening it, the water will oxidize and have bacteria.

Can't drink . Pure water must be consumed within 48 hours.

Water without oxygen? What will happen?

It is not advisable to re-burn again, because the mineral water is originally cooked water, and a large number of beneficial or unbeneficial things in raw water have been greatly reduced, and the water that is burned again is a secondary process that is more likely to produce substances harmful to the human body.

At most, it's just going to multiple toilets.
