In fact, most of us don't pay so much attention to it, but sometimes it is inevitable to have a stomachache after drinking raw water. In fact, if you distinguish carefully, there are still some differences. Regarding the difference between drinking raw water and drinking boiled water, I want to say the following aspects. If the raw water is tap water, after chlorination, chlorine and residual organic matter in the water will form toxic carcinogens such as halogenated hydrocarbons and chloroform, and the water will become safe drinking water after boiling for 3 minutes. After boiling water, some bacteria in the water will be killed, and some bleach left in the water will evaporate. From this point of view, boiled water is better than raw water.

But once boiled, raw water and distilled water are the same. Boiling water lacks oxygen, calcium and other inorganic substances. Drinking boiled water is useless to human cells. Compared with raw water, boiled water has a poor biochemical effect on human body. For example, goldfish can't be raised with cold water, and flowers will die if they are watered with cold water. Through these examples, it can be proved that the effects of raw water and boiled water are completely different. The oxygen content of raw water is many times higher than that of boiled water, which is beneficial to human health. When water is boiled, the oxygen content in it will drop sharply. Boiled water is lifeless water, which precipitates beneficial minerals such as calcium, magnesium and zinc needed by human body. In addition, the boiled raw water will promote the mixing of chlorine and organic matter in the water, and turn nitrate into nitrite (nitrite is a strong carcinogen), thus turning human hemoglobin into nitrosohemoglobin and making red blood cells lose their oxygen-carrying ability. Therefore, if the cleanliness of both is the same, raw water is more beneficial to human health than boiled water. Mainly speaking, raw water contains a variety of microorganisms, pathogens and a large number of bacteria. People who drink this water for a long time are easy to get infected with bacteria, and even get hepatitis in severe cases. Boiling water is much safer than raw water.

Water needs to be boiled for 3 minutes to drink, because drinking water without boiling is easy to get cancer.

People in the city drink tap water. After being sent to a waterworks, ordinary Jiang Hushui is chlorinated to remove impurities, such as microorganisms. However, at the same time, chlorine interacts with the residual organic matter in water, which will form toxic carcinogenic compounds such as halogenated hydrocarbons and chloroform. So try to drink boiled water instead of raw water.
