Drinking fountains have gradually become the “source of drinking water†in people’s daily lives. However, in recent days there has been a kind of voice saying that the hot and cold water in drinking fountains may cause poisoning and even cancer. Is this saying scientific? How to drink water from a drinking machine to be healthier? Drinking fountains hot and cold water will be poisoned by drinking it? Drinking hot and cold alternating water on a drinking fountain is a very common phenomenon. Some people began to pick up water without boiling. Or after the boiling water is finished and you do not want to wait, you will receive some hot and cold water. There are also some people who take a little boiling water and add some cold water to drink immediately. Although water in a cold and hot alternately, will increase the chance of bacterial reproduction, but the cold and hot water to drink how harmful to the body, the scientific community has not been conclusive. Whether the alternating hot and cold water on the drinking machine is harmful to the body, the most critical is the quality of bottled water. If the quality of bottled water is guaranteed, there is no big problem with the water and cold on the drinking fountains. If the quality of bottled water does not pass, or if tap water is directly filtered on a drinking fountain, hot and cold water can be used to poison the body. Because of this situation, cold water is "raw water" that contains a lot of bacteria. What water is yin and yang water? Yin and Yang drinking water on the human body what harm? The traditional Chinese medicine or folk remedies mean cold water and boiling water, or mixed water of well water and river water. It is mainly used as a prescription for medicine or medicine and is rarely consumed directly. Ming Li Shizhen's "Compendium of Materia Medica, Water, Health and Cooked Soup": "A new Yishui 100 boiling soup together and a uniform, it is cooked and cooked. Today people say that the yin and yang water.", "Liberation Daily" 1944.2.14: “In the summer, when well water is too cold, it should be mixed with water when drinking animals. The common name is 'yin and yang water' so that the animals do not get sick.†Nowadays, there is a definition of yin and yang water. One is the mixture of raw water and boiling water. When the amount of water in a fully automatic hot water boiler is insufficient, it will automatically add water. At this time, if the person taking the water does not pay attention or is eager to drink, the electric water boiler will flow out of the yin and yang water. Yin-Yang water may contain various pathogenic microorganisms, so drinking Yin-Yang water may cause various intestinal infectious diseases. The yin and yang water is produced in a single-cylinder floating ball boiler. Today's boiling water boilers adopt a twin-cylinder structure that separates boiling water from raw water. Many people are exposed to yin and yang water in their daily lives. For example, most of us drink water from drinking fountains. When the water in automatic hot water dispensers is insufficient, it will automatically add water. At this time, if the person taking the water does not pay attention or is eager to drink, the electric water boiler will flow out of the yin and yang water. If it is untreated water, the water directly from the faucet is mixed with boiled water. This yin and yang water is harmful to the body after drinking. Unsterilized water not only has a large amount of bacteria, but also causes human gastrointestinal dysfunction, even Can cause cholera. We generally drink bottled water, these processed, clean, direct-drinkable water and boiled water, which is currently mixed with yin and yang water. At present, there is no literature to support drinking and harmful to the body. However, we must ensure that the drinking fountains are clean, we must always clean the drinking fountains, and find some reliable bottled water businesses. Thousands of boiling water is what water? Does the drinking fountain repeatedly heat water? Thousands of boiling water is the water that has boiled on the stove for one night or a long time, and the water that is repeatedly boiled in the electric water heater. Most people think that this kind of water is boiled for too long and the content of non-volatile substances such as calcium and magnesium in the water and nitrite are high. Drinking this kind of water for a long time, harmful substances in the water will interfere with human gastrointestinal function, there will be temporary diarrhea, abdominal distension; toxic nitrite, but also cause the body to lack of oxygen, severe cases will be coma convulsions, and even death. This kind of water is generally inedible and can only be used as a study to extract harmful substances in water. The highest temperature reached by the drinking fountain heating water is 90°C, and it will not boil, so there is no “thousands of boiling water†to say that repeated heating of the water stored in the bladder for a long time will not have a fundamental impact on water quality, but may be in the water Mineral elements will be reduced or lost.
