Electric hot water tank is a must-have daily tool for families, and many people will use it to add hot water for hot drinks. However, it is said that reboiling water will have health effects and that doing so will cause harmful substances in the water to become irritated.
Therefore, it is recommended that after each use of the water tank, the unused water should be poured out and not reheated for repeated use. But is this view correct?
{9 Experts say these statements are not correct. 1. It is not easy to reduce chemical substancesDuring the boiling process, evaporation of water will leave dissolved substances in the water. Only when there is a long time of boiling, certain substances in the water will be reduced. But even if you reboil it, the amount of this kind of condensation is very small and will not achieve harmful concentrations.
For example, if you boil 1 liter of water in the morning and the fluoride content in the water is 1 mg/L (to meet the drinking water standard), when you reboil the second time, even if the water is evaporated, the increase in fluoride concentration will not affect your health.
2. Will the taste of water change?Some people think that reboiling water will change the taste of water, mainly because the mineral concentration in the water has slightly changed, or the dissolved oxygen in the water has decreased. These factors affect the taste of the water, although the degree of these changes depends on local water quality and personal taste preferences.
Basically speaking, as long as the water source meets the drinking water standards, it is still safe and easy to drink even if it is reboiled. Chemical substances in water will not condense to harmful concentrations in a short period of time. The only thing that may be affected is the taste, but it is more about the mineral content or oxygen content of water and will not cause health risks.
