Is it okay to drink mineral water all the time

Drinking water is essential in our lives. Many people like to carry a bottle of mineral water or hot water with them to quench their thirst when exercising or when they are thirsty. However, drinking water improperly can also cause cancer. I believe many people ignore such a problem. So, what kind of water can't be drunk? Next, I will tell you in detail what are the particulars of drinking water in our daily life.

1. Don’t drink overnight water

The nitrogen-containing organic matter in boiled water that has been left for a long time will continue to be decomposed into nitrite. At the same time, the intervention of microorganisms will inevitably accelerate the decomposition of the nitrogen-containing organic matter. The harm of nitrite to the body is well known. It has a strong ability to bind to hemoglobin in the body, which will hinder the normal oxygen transport function of the blood and is also carcinogenic. Therefore, it is best to drink boiled water on the same day.

2. Bottled water stored in the trunk for a long time cannot be drunk

When bottled water bottles are made, some plasticizers (also known as plasticizers in Taiwan) are added to the raw materials to help shape them. If the water is stored for too long, some plasticizers will dissolve into the water, and the drinking water will have a plastic taste. The plasticizer DEHP is 20 times more toxic than melamine. If a person drinks a 500 ml glass of water mixed with DEHP, it will exceed the daily intake limit.

Therefore, when you are abroad, bottled water should be stored at low temperature and away from light. Some people put a box of water in the trunk and take it out when they need to drink. This is not a good practice.

3. Water filtered by a water purification device should not be drunk for a long time

Household water purifiers perform deep processing on tap water. Its filter device contains substances such as activated carbon, which will absorb foreign matter such as particles, bacteria, viruses, etc. in the tap water. Therefore, after the water passes through the water purifier, it will become particularly bright, much brighter than tap water.

However, during the filtration process, minerals that are beneficial to the human body are easily filtered out. Therefore, from a safety perspective, it is necessary to install a water purifier. However, due to the lack of minerals and other trace elements needed by the human body, it is not suitable to drink water filtered by a water purifier for a long time, including purchasing barreled or bottled purified water.

4. Drinking "thousands of boiling water" can easily lead to poisoning

Some people in our daily lives are afraid that the water is not clean, so they boil the tap water for more than ten minutes before drinking it, which is the so-called "thousand-boil water".

Experts say this habit is wrong. In some places, the mineral content of tap water itself is relatively high. When water is boiled for a long time, the mineral elements in the water are concentrated after the water vapor evaporates. For example, the lead content of tap water itself is qualified, but after being boiled for a long time, the water is concentrated and the tap water becomes unqualified.

Also, tap water is disinfected with chlorine. Once some organic pollutants in the water combine with chlorine, they will form a disinfection by-product, which is a Class A carcinogen. The longer the burning time, the higher the amount of disinfection by-products produced. In the past, people said that steamer water cannot be drunk and is poisonous if drunk. Steamer water is boiled repeatedly, which is what this means.

How long is the appropriate heating time? Experiments have shown that it is best to turn off the fire as soon as the water boils. After the water boils, most bacteria can be killed. Generally speaking, except for bacteria with spores, other bacteria and viruses will die at around 80 degrees.

5. Not all mineral water is drinkable

Nowadays, many people think that as long as it is mineral water, it is good water, so some people specially take bottles and cans to the mountains to collect spring water. But in fact, not all mineral water is suitable for drinking. Mineral water in some areas.

For example, in the suburbs of Tianjin, the water contains a very high fluoride content. Although it is also mineral water, long-term drinking will lead to diseases such as fluorosis and dental fluorosis, so it is not suitable for drinking. As drinking natural mineral water, the country has strict restrictions, and the toxic and harmful metals or other minerals in the water cannot exceed the standard.

The ratio of minerals in water is also critical. If the sodium content is high, the taste will feel a bit salty; if the metal ion content is high, it will feel metallic; if the ratio is right, it will have a sweet taste. If the water tastes salty, metallic, or earthy when you drink it, there is something wrong with it.

6. Don’t drink tap water right away in the morning

Experts say that there is no problem if the tap water has just left the factory. Because the staff of our country's water plants are basically graduate students and doctoral graduates, their cultural level, technical level and other aspects are relatively high; in addition, the equipment of the water plants is also very advanced, all of which ensure the hygiene and safety of the tap water. However, during the transportation process, there are problems of secondary pollution such as pipelines, water towers, and water tanks.

In addition, many families now have the habit of drinking bottled water, and bottled water that seems to be well-sealed should also be consumed within three or four days. Because, if the bottled water is opened for a long time, bacteria will slip in through the water inlet, and the water dispenser will form a negative pressure when discharging water, and will inevitably inhale some air, and bacteria and microorganisms in the air will also "take advantage of the opportunity to enter." If you don't drink it within a short period of time, the bacteria will exceed the standard and the purified water will no longer be pure.
