The impact will not be severe, but it will cause some impurities and bacteria to enter the water in the bucket after expiration. The shelf life of bottled water has little to do with temperature, generally 7 days, and the bacteria multiply faster when the water comes into contact with the air, even a water dispenser with a water purification function cannot guarantee that the water is absolutely clean.
Drinking water experts say they want to drink as little water as possible for long periods of time. If you drink water for a long time, then drink more fresh water, and the water stored in the body can be excreted in the form of urine, experts remind consumers: the shelf life of bottled water after opening is generally only 3 days, and the bottled water that most people drink at home may be "expired water"; If the water dispenser placed in the home or office is not cleaned for 10 days, it is "spending money to buy a disease".

There shouldn't be a big problem, but you have to pay attention to it in the future, and it is not recommended that you drink this mineral water, it is best to drink mineral water, followed by mountain spring water, and then pure water, there is really no way to drink mineral water.
Let me tell you the difference between these types of water, most people may not understand the difference between water.
1. The production process of pure water is to remove all the impurities and minerals in the water by chemical methods, which is very pure, but there is no nutrition at all, such as Wahaha pure water. However, the production process of mineral water represented by Master Kong mineral water is to artificially add mineralized liquid on the basis of pure water, and most of the artificially added mineralized liquid belongs to calcium carbonate, sulfate and the like, which cannot be absorbed by the human body, but will react with the original calcium in the human body and take away the calcium example. Only natural mineral water contains minerals that are most easily absorbed by the body.
The content of alkaline mineral ions in the human body determines the change in the pH of body fluids, and the more alkaline mineral ions there are, the higher the degree of alkalinity of body fluids, and many people have recognized this problem.
But at the same time, there is a misconception: only the intake of minerals from food is important, and the absorption of minerals in water is neglected.
The United Nations Drinking Water Health Standards (published in 1982) state that "the absorption of essential minerals from water shall not be less than 5% and up to 39% shall be absorbed".
Animal experiments on water found that the experimental mice ate the same diet and drank different water (one group drank weakly alkaline water containing natural minerals, and the other group drank acidic purified water), and there were significant differences in the level of mineral content in the body. A group of mice that drank acidic purified water continued to experience a continuous decline in mineral levels over time.
2. When we buy water daily, we must pay attention to the information marked on the bottle label, which belongs to mineral water, pure water, mineral water, drinking water, mountain spring water, and the best is to drink mineral water (the bottle label will be clearly marked with the words "natural mineral water", mineral water depends on the water source, currently in China, the internationally recognized mineral water of Qingdao Laoshan water source is the best, so it is recommended that you drink the mineral water of these local water sources, at present I know that there are blue mineral water, Laoshan mineral water is good), This is followed by mountain spring water (such as Nongfu Spring), then pure water (Wahaha pure water), and finally mineral water (Master Kong, Coca-Cola's ice dew, etc.). Now some large companies in the market have begun to make water, which is very cheap, about one yuan a bottle, such as Coca-Cola, Pepsi, etc., it is recommended that you do not drink it, because these waters are only thirst-quenching functions and have no other benefits for the body.

There is no adverse reaction if you drink less, but the big deal is to pull your neck... If you drink too much, it will cause gastrointestinal disorders, so it is recommended to drink less or not at all. The teeth are uncomfortable and the face is a little painful, it will not be caused by drinking water, it may be caused by the fire in the autumn.

Drinking less often is nothing, and it can also strengthen people's resistance. But don't drink it next time, you should get sick if you drink too much.

Bottled mineral water, if it has passed its expiration date.
The most pointed out is that Li Hao should not drink.
so as not to bring unnecessary side effects to the body. You can drink plenty of warm water, pay attention to rest, and avoid exertion. Adopt a normal life. Mineral water that expires for a long time may lead to the growth of bacteria. so as not to affect the gastrointestinal function of spring disassembly.
The shelf life of the best bottled purified water on the market is generally 3 months, and there are a few pure water with a shelf life of only one month, so it is easy for large-capacity bottled purified water to expire. Once purified water is opened, it is best to drink it within 15 days. Although there is no change in the appearance and taste of purified water that has been left for a long time, it is likely that the bacteria have exceeded the standard, and drinking it is easy to cause physical discomfort.
Correct understanding of pure water:
Bottled water does not have to add preservatives only if it is too late.
Lu Qing, an associate professor at the School of Public Health at Tongji Medical College at Huazhong University of Science and Technology, said that when the water container is sealed, it is impossible for outside air and microorganisms to enter the container.
When the water is opened, both air and microorganisms come into contact with the water, which is conducive to the growth of bacteria and microorganisms. Therefore, in the case of opening, the shelf life of purified water and mineral water is around 15 days.

It is best not to drink purified water after it expires. Although drinking purified water meets hygienic standards, there are still a small number of microorganisms present. Purified water that expires may cause bacteria in the water to exceed the standard, causing physical discomfort after drinking.
Purified water shelf life.
Pure water itself is not free of any impurities and bacteria, but it is lower than the national standard and can be regarded as pure water. Pure water is affected by the preservation environment, and the microorganisms inside it will change, and the water will deteriorate over time.
The shelf life of bottled purified water is generally 3 months, and there are a few bottled purified water with a shelf life of only 1 month. The shelf life of bottled pure water is generally 1-2 years.
Purified water is susceptible to microbial contamination, so it is recommended to drink it as soon as possible once it has been opened. Especially in the hot summer, the heat is more likely to breed bacteria and cause the water to deteriorate.
Key features: The reverse osmosis membrane that filters purified water removes bacterial impurities from the water, which can replenish the body with the water it needs and help excrete toxins from the body in a short period of time.
Drinking water is mainly for hydration, not for the purpose of replenishing trace elements. The minerals and trace elements consumed by the human body are mainly from vegetables, fruits, rice, meat, etc., rather than from drinking water.
Diet is the main way for the body to take in nutrients, and water plays a very small role. Zhong Kai, deputy director of Kexin Food and Nutrition Information Exchange Center, said, "Nutrients are not washed away by water, and people are not sieves, how can it be so simple." Nutrient loss is related to natural conditions, age, exercise, physique, etc., and it is not up to drinking water to play a decisive role.
Water containing too many minerals in the body will cause unnecessary burden on the human body, and some minerals may not be absorbed by the human body, and if they accumulate in the body for a long time, it will directly affect human health.

Water does not expire, but bottled water that has been left out for a long time should not be consumed. Neither water in nature nor water in a bottle has an expiration date. The expiration date is only relative to humans, and drinking it within this date will not cause harm to the human body.
Water that is often said to expire is due to the increase of bacteria in the water, which will cause the water to deteriorate, and drinking this water will cause the risk of bacterial infection. Theoretically, the shelf life of sealed bottled water should be very long, as the bottled water itself is sterilized. Moreover, there are very few nutrients in the water, which makes it difficult to maintain the survival of bacteria.
However, since most of the water bottles are made of plastic, for example, PET, or polyethylene terephthalate (the plastic bottle marked with the number "1" on the bottom is made of PET), these polymers are not stable, they will age over time, releasing some toxic low molecules, which can cause water to deteriorate.
Therefore, water that has been left out for a long time should not be drinkable. This is especially true when placed in a hot environment or exposed to sunlight, which accelerates the aging of plastics.

Mineral water will expire, the shelf life of mineral water is one year, and mineral water will spoil after the expiration date.
As long as the water in the river is fluid, it will never deteriorate unless it is polluted without control.
Water itself has the ability to clean itself, and when the water is constantly flowing, it can continuously increase its oxygen content, so that the water always remains "fresh".
-
Water does not expire, except for humans, other animals are basically drinking water in nature, but there are many standards in the human concept to classify the quality of water.
The water in the mineral water will not expire, the shelf life written on the package refers to the shelf life of the bottle, the bottle of mineral water is plastic, generally Class 1 plastic, can not be stored for a long time, it is a disposable, can not be kept for continued use.
-
Mineral water expires. The shelf life of mineral water is one year, when the mineral water has been opened, the germs in the air will enter the water, there are about 5000 germs in a cubic meter of gas, and the germs will breed and grow for a long time, affecting the health of the mineral water, so the mineral water after opening should be drunk as soon as possible, and should not be put for a long time.
Water is an inorganic substance composed of hydrogen and oxygen, which is non-toxic and drinkable. It is a colorless and odorless transparent liquid at room temperature and pressure, and is known as the source of human life.
Water is one of the most common substances on Earth, with 71% of the Earth's surface covered by water. It is an important resource for the survival of all life, including inorganic chemistry and human beings, and it is also the most important component of living organisms.
Pure water is a very weak electrolyte with very weak electrical conductivity. Water in daily life has more anions and cations due to the dissolution of other electrolytes, so it has more obvious conductivity.

No harm, but try not to drink expired purified water.
The human body can get at least 30 inorganic salts in the normal diet, and there are these inorganic salts in the tap water, but once the person is processed and purified, the content of inorganic salts will be greatly reduced, and even disappear, the human body can not get the supplement of inorganic salts, and the immunity will naturally decline, and the health will reach a threat, and in severe cases, it will also cause diseases.
Long-term drinking of filtered pure water, so that some of the nutrients beneficial to the body in the human body are lost, without minerals and trace elements, the body's immunity will gradually decrease, the immune system will gradually degenerate, can not carry out its own immune work, in the long run, the body will be in a sub-healthy state, especially the elderly, children drink pregnant women can not drink pure water for a long time.

If you drink expired purified water, there is a risk of diarrhea, and there are no other consequences, try not to drink expired bottled water.
The most common way of pure water is the bottled water used in the home or office, the advantage of pure water is that it is clean and hygienic, and it is usually drunk more, but in fact, drinking pure water for a long time is not good for the body, and the harm of drinking pure water for a long time:
1. Purified water loses the activity of positive physiological functions due to "purity" (removal of trace elements and minerals that are beneficial to human health) and becomes "stagnant water" with degraded functions. Long-term drinking is easy to cause sub-health problems such as limb weakness and lack of energy, especially for the development of the fetus and the growth of children.
2. Purified water is weakly acidic water (pH 5 7), long-term drinking can destroy the normal acid-base balance relationship of the human body, resulting in acidification of the human body.
3. Purified water has a strong solubility ability, and after drinking a large amount of it, the original trace elements and nutrients in the body will be quickly dissolved in the pure water, and then excreted from the body, so that the nutrients in the human body are out of balance, resulting in malnutrition and decreased immunity.
-
In fact, pure water is not a big problem, and this deadline is proposed to prevent the impurities in the drinking fountain from being sucked into the water by the suction of the bucket and polluting the water source.
For the sake of your own health, it is better to drink it before the expiration date. As for bacteria, there are a lot of them, I can't say for sure.
Look at the concept of water purifier, if some minerals are retained, it is fine, because a large part of the minerals in the human body are ingested through water, and the intake from food alone cannot be satisfied. If the mineral content in the water is low or even none, then you should usually supplement with mineral tablets. >>>More
Scientific research and practice have proven that honey has strong antibacterial ability and is the only food in the world that does not spoil. In 1913, American archaeologists found a jar of honey in the ancient tombs of the pyramids in Egypt, which was identified as having lasted for more than 3,300 years, but it has not deteriorated at all and is still edible. It can be seen that truly mature honey is completely edible after a long time, and there is no strict shelf life, but as a food market, according to the "Food Law", the shelf life is required to be marked on the food commodity, so honey manufacturers generally set the shelf life of honey at 2 years. >>>More

White sugar is expired.
If it is ordinary edible white sugar and sucrose is used as extract, it is divided into 18-24 months according to different factors such as outer packaging according to relevant national regulations. In addition, the storage of white sugar should be kept away from light, and the temperature should be controlled below 20°, so that the sugar can be dried for a long time and its properties will not change. >>>More
