Water has a lot to do with the human body. Tap water cannot be drunk raw, otherwise it will cause bacterial infection. In severe cases, it will cause diarrhea. In severe cases, it will have a bad impact on the health of the body. Although hot water can remove some bacteria, it will also pollute the environment.
If the water is contaminated, or the secondary water supply system is not clean, it is easy to breed bacteria. Many adults will say that it will be fine after cooking, but it will take a certain amount of time to cook, and bacteria that are resistant to high temperatures cannot be killed at all. Heat-resistant Enterotoxin : It is not resistant to high temperature and loses activity within 60℃ for 30 min; it is not resistant to high temperature enterotoxin: It has good high temperature stability and will not be destroyed after 20 min. When secondary water supply occurs, siltation, water tower is not cleaned for a long time, water pipes are aging, and process is not adapted to the current situation, etc., it will lead to the production of E. coli .
Boiling water can only kill most bacteria and viruses, and other harmful heavy metals, chemicals, and impurities cannot be removed. Water is clean and safe because it can remove harmful chlorine from the water when it is boiling. But unfortunately, during the boiling process, due to the high temperature, it will lead to the generation of " trihalomethane ", which will cause greater harm to the body.
Everyone says boiled water can be disinfected, but what about those dead bacteria? Did we drink it all? Although bacteria die at high temperatures, the body is still there, forming a "pyroplasma". Once it enters the body, it will cause diseases and absorb harmful water to the body. Drinking too much can cause side effects such as headache, low fever, gastrointestinal discomfort, arthritis, etc. Boiling boils in boiling water will produce heavy metals arsenide , nitrite , etc.
In addition, hot water cannot be boiled repeatedly, otherwise a substance called nitrite will be generated. If the water is repeatedly heated, the nitrate will be converted into nitrite. The nitrite will convert the hemoglobin in the human body into nitrite hemoglobin, which will cause the red blood cells to be unable to transport oxygen . So, please don't boil too much water for your body.
