will you be poisoned if you mix hot and cold water from the water dispenser
It is a common phenomenon to drink hot and cold water in the water dispenser. Some people began to receive water before it boiled. Or after the boiling water is collected, they don’t want to wait, and then they receive some hot and cold water. Some people take a little boiled water first and then add a little cold water for immediate drinking. Although the repeated alternation of cold and hot water will increase the chances of bacterial reproduction, the scientific community has not yet reached a conclusion on how harmful drinking cold and hot water is to the body.
will you be poisoned if you mix hot and cold water
The quality of bottled water is the key to whether the alternating hot and cold water on the water dispenser is harmful to the body. If the quality of bottled water is guaranteed, there is no big problem with the water cooling and hot drinking on the water dispenser. If the quality of bottled water is not up to standard, or the tap water is directly filtered with a filter bucket on the water dispenser, drinking cold and hot water alternately may poison the body. Because in this case, cold water is “raw water” containing a large number of bacteria.
what is Yin Yang water? What harm does drinking Yin Yang water do to human body
In traditional Chinese medicine or folk prescriptions, it refers to cold water and boiled water, or mixed water of well water and river water. It is mainly used to adjust medicine or to introduce medicine. It is rarely drunk directly at ordinary times.
Nowadays, there are two definitions of yin and Yang water. One is the water mixed with raw water and boiled water. When the water in the full-automatic hot water heater is insufficient, it will automatically add water. At this time, if the person receiving the boiled water does not pay attention or is in a hurry to drink, the electric water heater will flow out 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 Yang water is mostly generated from the floating ball water boiler with single cylinder structure. Today’s boiling water boiler adopts a double cylinder structure to separate boiling water from raw water.
Many people will be exposed to Yin and Yang water in their daily life. For example, a large part of us drink water from water dispensers. When the water in the fully automatic hot water dispenser is insufficient, it will automatically add water. At this time, if the person receiving the boiled water does not pay attention or is in a hurry to drink, the electric water heater will flow out Yin and Yang water. If it is untreated water, the water directly from the faucet is mixed with boiled water. This yin-yang water will be harmful to the body only after drinking. The water that has not been disinfected will not only contain a large number of bacteria, but also cause gastrointestinal dysfunction, and even cause cholera. The barreled water we usually drink, which is the yin-yang water mixed with the treated, clean, directly drinkable water and boiled water, has not been proved harmful to our health. However, we must ensure that the water dispenser is clean, wash the water dispenser regularly, and find some reliable bottled water merchants.
what is thousand boiling water? Is the water repeatedly heated by the water dispenser thousand boiling water
Thousand boiling water is water that has been boiling on the stove for one night or a long time, and water that is repeatedly boiled in the electric water heater. It is generally believed that this kind of water has a high content of nonvolatile substances such as calcium, magnesium and nitrite because it is boiled for too long. If you drink this water for a long time, the harmful substances in the water will interfere with the gastrointestinal function of people, resulting in temporary diarrhea and abdominal distension; Toxic nitrite will also cause hypoxia, and even coma, convulsion and even death in severe cases. This kind of water is generally inedible and can only be used for extracting harmful substances in water.
The maximum temperature of the water heated by the water dispenser is 90 ℃, and it will not boil. Therefore, there is no “thousand boiling water”. Repeated heating of the water stored in the tank for a long time will not have a fundamental impact on the water quality, but the mineral elements in the water may be reduced or lost.
