Common sense of drinking water safety
First, the daily drinking water is insufficient. Some people think that if you are not thirsty, you do not need to drink water. In fact, cells in the human body will lose water through constant metabolism, waste elimination and heat emission. Therefore, it is necessary to maintain a balance between daily water intake and discharge. When drinking water is insufficient, if the body is seriously short of water, the osmotic pressure of blood circulation will increase. If the water supply is not timely at this time, the water in intracellular fluid will flow to the tissue fluid, resulting in intracellular dehydration. If you wait until you are thirsty to drink water, it means that the water loss in your body is serious, so you should develop the habit of drinking water at any time.
Second, drinking water equals drinking water. Many people don't like drinking water, but prefer to drink sweet and sour drinks. In fact, drinks can't replace drinking water. Drinks are not only easy to cause anorexia and hydrophobicity, but also cause malnutrition in the long run. Drinking too much acidic drinks will make human blood acidic, which is not conducive to blood circulation. The accumulation of lactic acid in muscles is prone to fatigue, which in turn leads to the decline of human immunity and is prone to colds, dental caries, periodontitis and other diseases.
Third, drink tap water. Some people mistakenly think that drinking raw tap water is nutritious, especially in summer, when you turn on the tap, you are prone to intestinal diseases such as dysentery, typhoid fever and cholera.
Fourth, you must drink pure water. Pure water is the water obtained by processing and sterilizing natural mineral water, which contains almost no impurities and trace elements. As daily drinking water, its price is high and it is difficult to meet people's needs. In addition, drinking pure water without any nutrition for a long time may lead to diseases due to lack of various elements, from poor diet, sleep and fatigue to neurological disorders, osteoporosis, anemia and so on.
Five, drink thousands of boiled water for a long time. We advocate drinking boiled water, but we are against drinking boiled water for a long time. The water that has been boiled for a long time on the stove and repeatedly in the electric water heater is called boiling water. The content of heavy metals such as calcium and magnesium and nitrite in its water is very high. Drinking this water for a long time will interfere with people's gastrointestinal function, leading to diarrhea and abdominal distension, while toxic nitrite will also cause hypoxia in the body, causing neurological, urinary and hematopoietic diseases.
Common sense of drinking water health
Water is the source of life. We need to drink water every day to supplement our needs, but is the water we drink really healthy?
The office basically uses bottled water, that is, tap water is filtered by some large-scale water purification equipment, which basically fails to pass the national test. In addition to the initial wading approval, normal water production and sales do not need to test whether the water meets the standard, and it can be said that the replacement of water purification filtration equipment for water purification is not so timely, and there will be secondary pollution, so I remind white-collar friends that water should be boiled before drinking. If possible, you can buy a Birand net kettle or a kitten rabbit hydrogen-rich water purification cup and purify it before drinking water, which is more reassuring. Most of the time is spent in the office, so it is quite necessary.
Tap water is basically used at home, some have water purifiers installed at home, and some drink water from community water dispensers. Either way, there is still something unscientific. Of course, tap water is quite unsanitary, because the tap water in our country has not reached the drinking standard at all, but has undergone preliminary filtration and sterilization. The national standard is very low, and impurities, silt, rust, some toxic and harmful substances and microorganisms in the water have not been removed at all. If drinking such water for a long time is very harmful to the health, then there is a certain reason why the number of cancer patients is increasing year by year. There is also a water purifier, mainly installed in the kitchen. There are many kinds of water purifiers on the market, mainly divided into two types. One is ultrafiltration water purifier, which will retain minerals and trace elements beneficial to human body in the process of purifying water. In this case, the common problem is that the scale in the north is serious and cannot be completely removed. There will still be scale in boiling water, and the filter element will wear faster. There is also a water purifier. The purified water is very pure. Although this kind of water effectively purifies the water, the taste of the water is not very good, and it is unfavorable to drink it for a long time, especially for the elderly and children, because the minerals and trace elements commonly needed by the human body are supplemented by drinking water. The large-scale drinking fountains in the community have good nozzle feeling and water purification effect, and are also relatively affordable, but now many filter elements are not replaced in time, and sometimes the water is not so hygienic. Therefore, if you live at home, it is recommended to install a whole house water purification system. First, install a 3M backwash prefilter at the water inlet, and then install different water purification devices for kitchen water and bath water. It is recommended to install a five-stage ultrafiltration water purifier in the kitchen, which is relatively more conducive to health. If you use bath water, install a large central water purifier.
Matters needing attention in healthy drinking water knowledge
Tap water that meets the national hygienic standard for drinking water is produced by strictly controlling the quality of waterworks. Tap water can be safely drunk after boiling, but tap water can't be directly drunk, which brings inconvenience to our life. In addition, the water tanks of some high-rise buildings are also in danger of being polluted, and the aging of water pipes makes the quality of tap water less and less trustworthy.
Beware of the "stagnant water killer" in the morning
The faucet that stopped for one night and the tap water in the nearby water pipe are still. This water will hydrate with the metal pipe wall and the metal cavity of the faucet to form metal polluted water, and the microorganisms on the wall of the tap water pipe will also multiply in large numbers. According to analysis, this kind of water contains substances harmful to human body, so it is not suitable for drinking, brushing teeth and gargling. Medical experts remind people that after turning on the tap in the morning, they should first release this harmful "stagnant water" before they can receive water for use.
Drink only boiled tap water.
Although the sanitary quality of tap water meets the national hygienic standard, it is best not to drink tap water that is not boiled, because tap water is domestic drinking water, not direct drinking water, and there is a huge difference between them. In addition, boiled water left for more than 24 hours after boiling is not suitable for drinking.
Refuse to drink boiled water repeatedly
Repeatedly boiled water is not suitable for drinking because of its high nitrite concentration. Drinking this water often can cause nitrite poisoning, digestive, nervous, urinary and hematopoietic diseases, and even lead to premature aging.
Don't drink boiled water.
Experts pointed out that drinking tap water that is not completely boiled often increases the possibility of bladder cancer and rectal cancer by 2 1%-38%. Because some harmful bacteria in tap water must reach 100 degrees Celsius to be completely killed.
