It is often said that repeatedly boiled water and re-boiled water are not good for your health after consumption. However, this claim currently has no scientific conclusion; it can only be said that in the process of repeated heating and cooling, water provides more opportunities for bacterial growth.
"Yin-yang water" is a mixture of raw water and boiled water in medical terms, and also a mixture of cooled boiled water and boiled water. In fact, in daily life, many people come into contact with "yin-yang water," such as the water from a water dispenser. When the hot water tank is low on water, it automatically refills. At this time, if the person getting the hot water is not paying attention or is in a hurry to drink, the dispenser will dispense "yin-yang water."
However, if this water is clean, treated bottled water from a regular manufacturer, mixing cold and hot water will not have any adverse effects on the body. But if the water is untreated, this "yin-yang water" may contain a large number of bacteria, which can disrupt a person's gastrointestinal function and even cause diseases like diarrhea.
It is recommended to drink freshly boiled water to ensure good health. In addition, it is also important to regularly clean and disinfect your water dispenser. This not only ensures the proper functioning of the dispenser but also reduces bacterial growth in the water source.
