What are the disadvantages of drinking water from the water dispenser regularly?

If people drink purified water for a long time, it is harmful to health. Because:

1) Purified water not only removes all harmful substances to the human body, but also removes many "essential trace elements" that are very important for human health. The human body needs these elements in very small quantities and can be met in a normal diet every day. Now, this essential trace element that can be obtained from normal drinking water is removed by drinking purified water.

This does not meet the normal needs of the human body. In the long run, it will cause irreparable harm to health. The harm is chronic, imperceptible, irreversible, and endangers future generations.

Among them, the three elements that have the greatest impact are zinc, magnesium, and iodine. Although these elements are very small in water, they are already very lacking in food, and now this trace element is removed from the water, which is even worse. These three elements are directly related to reproductive development and intellectual development, and when they are deficient, they affect the development of the nervous system and even affect future generations.

2) In the normal diet, there are many inorganic salts that can be satisfied, such as tap water, there are 30 kinds of inorganic salts that the human body needs. Now, by removing this part of the water, the human body cannot replenish the amount of inorganic salts it needs. Over time, it will cause nutritional imbalance, and people's health will also be affected, and in severe cases, it will lead to diseases.

3) Pure water is not pure. The preparation of pure water is very complicated, and since it is a high-tech achievement, it certainly has a high technical content. Not everyone can produce it.

These ion exchangers and membrane filters require frequent technical treatment and cleaning, which is called ion exchanger and membrane filter regeneration technology. However, most water purification plants do not master this regeneration technology. As a result, a large amount of bacteria and dirt are enriched in the exchanger and filter, and the longer it is used, the more bacteria and dirt accumulate, and the water filtered out here is much higher than the amount of bacteria and dirt in tap water.

In other words, the filter has become a source of contamination. Therefore, according to the data released by the relevant testing departments, the pass rate of pure water testing is not high every year. A lot of substandard "pure water" is sold all over the street, and people drink it as pure water, which is much more harmful than tap water (because tap water, everyone knows that it needs to be boiled before drinking).

4) After pure water enters the human body, because it does not contain all kinds of positive and negative ions, it has strong solubility performance, which can not only dissolve all kinds of harmful wastes and harmful trace elements, but also discharge them from the body. At the same time, it can also dissolve various essential trace elements that are very needed by the human body and be excreted from the body.

5) The molecular structure of pure water will be rearranged after the water purifier treatment, so that the structure of pure water molecules becomes extremely tandem and linearized. This water molecule, which does not easily pass through the cell membrane, causes the body's beneficial life-related elements to be lost outside the body. Some sensitive people feel thirstier the more they drink, and the more thirsty they are, the more they want to drink.

Drinking purified water for a long time will make you feel weak. This has a more prominent *** for teenagers who are growing their bodies. To this end, Shanghai has clearly stipulated that primary and secondary school students are restricted from drinking purified water.

The water from the water dispenser is pure water.

Drinking it regularly will deplete the ions that the body needs itself, resulting in ion disorders or imbalances.

You can't drink it, and sometimes the water from the water dispenser can't be boiled, so there may be bacteria, and it may also cause cancer, which is very harmful to health.

The water from the water dispenser is drinkable, so it has no effect on health, because the water we usually drink is this water.

This is very dangerous, sometimes the temperature of the water dispenser is not high enough, there is no way to kill the bacteria well, and there is no way to remove impurities, and the consequences are very serious.

Someone has done an experiment that the water in the water dispenser is boiled for 5 minutes, and the temperature in the water is measured after the water is boiled, while the temperature of the water in the electric kettle and gas stove is close to or equal to 100 after boiling. From the results of small experiments, it can be seen that the water in the water dispenser is not heated to reach the boiling point.

Both tap water and bottled water are raw water, which contains bacteria and microorganisms, and chlorine, which is used for disinfection in tap water, may also be present in bottled water. Therefore, when drinking water, it should be boiled and then heated for 2-3 minutes, otherwise it will not be able to effectively kill bacteria and microorganisms, and it will not be able to volatilize some of the chlorine.

In addition, the water dispenser also has the function of repeated heating, which seems to be very convenient to drink, but in fact it increases the nitrite content in the water, even if it does not meet the poisoning standard, long-term drinking will also harm the human body. Therefore, it is not recommended to drink boiled water from the water dispenser for a long time.

harmful. The direct drinking water machine has a built-in RO membrane for filtration, and the RO membrane has a service life, and if it cannot be replaced in time, it will cause secondary pollution. If the bucket is used for a long time, it is also easy to breed bacteria and harm your health.

The water source of the direct drinking water machine is tap water, and although the RO membrane can filter many bacteria, impurities and chemical components, about 90% of the trace elements in the water that are beneficial to the body are also filtered out.

Filtered water is called "soft water", and the content of minerals such as calcium and magnesium is very low, and long-term consumption may increase the risk of cardiovascular and cerebrovascular diseases. In addition, waste of resources is also a problem. The filtration ratio of the direct drinking water machine is 1 (pure water):

3 (raw water), i.e. 3 tons of tap water can be filtered into 1 ton of purified water, and the rest is discharged into the sewer.

The introduction of direct drinking water dispensers is an agreement between production enterprises and communities, and safety and health depend on the consciousness of enterprises, and it is urgent to strengthen supervision. For example, a third-party regulatory department has been set up to record direct drinking water dispensers and regularly sample water samples; Relevant departments shall punish violations such as the use of substandard equipment and lack of business licenses; Advocate the installation of tailwater facilities, etc.

The property in the community should also take responsibility, send special personnel to clean and maintain the equipment, and try to place the direct drinking water dispenser in indoor places. She also suggested that residents should not drink direct drinking water for a long time and alone, but can drink it in exchange with bottled water and tap water, or drink tap water filtered by activated carbon filters, which can retain the minerals in the water to the greatest extent and maintain good health.

Harmful. 1. When taking water from the water dispenser, how much volume of water is released from the faucet, at the same time, the same volume of air will be added from the surrounding environment into the bottled water, and the indoor air contains a large amount of dust, bacteria and other harmful substances, which enter the bottled water of the water dispenser, causing secondary pollution of drinking water and water dispenser.

In addition, after the water dispenser with mineral water as the water source is heated and boiled, the hydrogen atoms in the bicarbonate in the water are decomposed into carbonate ions, and they combine with minerals such as calcium and magnesium in the mineral water to form insoluble precipitates in water, which will be deposited at the bottom of the water tank of the water dispenser for a long time to produce scale, which not only affects the water quality, but also affects the heating effect of the water dispenser and is easy to produce noise.

2. The neck part of the barrel of bottled water is the place where it is in closest contact with the "smart seat" of the water dispenser. Some manufacturers do not strictly disinfect the bottleneck part, the sealing performance is not enough, and even use inferior bottle caps, and the staff will take off the bottleneck bottle caps during transportation, so that the water is polluted twice.

The water inlet, inner wall of the water storage tank and cold water pipes of the water dispenser are very susceptible to the growth of bacteria due to the appropriate temperature, even when using qualified bottled water. If you do not pay attention to cleaning, it will cause diseases of the human digestive system and urinary system.

First, the water dispenser's own defects: long-term boiling produces "thousands of boiling water".

After drinking water is repeatedly heated in the hot tank, it will form "a thousand boiling water". This water contains harmful substances such as heavy metals and arsenides, and drinking it for a long time will harm gastrointestinal health.

Scale becomes an "additive": According to the report issued by the national environmental testing department, if the inner tank of the traditional water dispenser is not cleaned for more than 3 months, a large number of bacteria, residues and even bloodworms will breed, which will attach to the inner wall of the hot bile and become a toxic "additive".

When these substances enter the human body, they can cause diseases of the digestive, nervous, urinary and hematopoietic systems.

Second, the secondary pollution of water dispensers.

Each water dispenser has 5 parts that communicate with the outside world, namely two faucets, water inlet, air outlet and sewage outlet. The secondary pollution of the water dispenser is mainly due to the dust in the air carrying a large number of microorganisms, algae and so on with the air into the water dispenser, especially the air outlet, the sewage outlet is easy to form a dead end, microorganisms multiply, but also pollute the bottled water.

When the water, directly put the barrel neck of the bottled water upside down on the seat of the water dispenser, after the bottled water is loaded into the water dispenser, every liter released, there must be a corresponding liter of air entrained dust, E. coli, staphylococcus, mold and other bacteria are also attached to the inside of the water dispenser, and then the bacteria will continue to multiply in the water dispenser, showing light yellow and sticky and slippery.

Over time, it can reach the level of danger to human health.

Water dispensers are to be cleaned regularly.
