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.

Try not to drink with that. Because many plastic cups are made of industrial waste gas raw materials, they are very unclean, and once poured into hot water, they will release toxins. So the reason why many companies use plastic cups instead of paper cups for employees is that the cost of plastic cups is very low.
So try not to drink water from a plastic cup in the future!

As long as it is not made of inferior plastic, there is no problem.
Why use plastic cups?
We want to advocate environmental protection.

Unhygienic. In particular, do not drink hot water.

Hello dear. Plastic cups are generally harmful when drinking hot water. It is best not to use plastic cups when drinking water, especially hot water, because the influence of temperature will release the clump dry benzene seepage hole in the plastic.
If a person drinks the above harmful substances for a long time, it is easy to cause cancer. Therefore, it is best to use a glass or ceramic cup to drink hot water, which is good for human health. Nowadays, the incidence of cancer is increasing year by year, so it is important to take good precautions, and it is best not to drink water from plastic cups.

There are certain harms in drinking hot water from a plastic cup, but it can't be generalized, it still depends on the number at the bottom of the cup.
Generally speaking, plastic cups made of PP and HDPE are safer and can be used to drink hot water; When the tritan material is heated, it will not release any bisphenol A, bisphenol S and any other bisphenol substances that are harmful to the nucleated human body, and it is also more suitable for holding hot water.
Some plastic cups will add plasticizers, and the hot water will volatilize the odor, resulting in the dissolution of toxic substances, thus causing harm to the human body. In addition, the internal microstructure of the plastic has many pores, which hide trapped dirt, and it is easy to breed bacteria if it is not cleaned.
These plastics contain a substance called polypropylene or PVC polyvinyl chloride, which is toxic, so when buying plastic cups, the car should open the lid and smell whether there is plastic or other smells, and all odors are unqualified.
Plastic cups have odor treatments
1. Boiling water to remove odor: If the plastic water cup has a strong odor, you can soak it in freshly boiled water, so that the harmful substances in the plastic cup can be brought out faster, and the odor of the plastic cup will be much lighter after soaking.
2. White vinegar to remove odor: white vinegar itself has the effect of cleaning and removing odors, so you can use white vinegar to soak plastic cups. Before soaking, wash the plastic cup with dish soap, then mix it with boiling water and white vinegar before soaking.
3. Baking soda to remove odor: Because baking soda has the ability to decontaminate and remove odors, baking soda can also be used to remove the odor of plastic water cups. You can put some baking soda in the water and soak a plastic cup in it.
4. Orange peel to remove odor: orange itself has a strong fragrance, and orange peel can also quickly eliminate the odor of plastic cups. After putting the fresh orange peel into the plastic cup, tighten the plastic cup with the cap and wash it with water the next day, you will find that the odor is gone.
Disposable paper cups contain bisphenol A
Bisphenol A is not only widely added to plastic daily necessities, but also can be found in paper products. Relevant experts have selected some common daily necessities for group comparison and measurement. First of all, the comparative determination of the bisphenol A content of disposable paper cups, disposable plastic cups and disposable lunch boxes shows that the concentration of bisphenol A in disposable paper cups is the highest, nearly 30 times that of disposable plastic cups, which is very surprising. >>>More

1. Damage to respiratory function: Disposable chopsticks must be fumigated with sulfur during the production process, so SO2 will be released when exposed to heat during use, eroding the mucosa of the respiratory tract. >>>More
With the rapid development of social economy, our living standards have been greatly improved, and now we are paying more and more attention to the problem of personal health. In fact, our physical health has a lot to do with our privacy, and of course, it is also inseparable from the river water in our daily life. Therefore, some people will have such doubts, that is, to drink boiling water and cold water from the water dispenser, is this harmful to the body? >>>More
The hazards of plastic bags are:
1. Bringing serious environmental problems, waste plastics will not only occupy a large amount of land with landfills, but also the occupied land will not be restored for a long time, affecting the sustainable use of land. If waste plastic products that enter household waste are landfilled, it will take 2 years to degrade them. Moreover, plastic bags use petroleum as raw materials, which not only consumes a lot of resources, but also cannot be decomposed, and buried in the ground will pollute land and rivers. >>>More
