There is an opinion that boiling the same water several times is very harmful.
It is believed that repeated boiling increases the amount of impurities contained in water.
However, experts say that the harm from repeated boiling is exaggerated.
Is it possible to boil water several times?
Yes, you can. There is no reason to fear an increase in the content of impurities in the water.
The concentration of impurities after repeated boiling depends on their initial concentration.
If the amount of impurities is within the norm, boiling the water will not make it toxic.
As for the effect on the taste of water, repeated boiling really does change it for the worse.
However, in everyday life, the same water is usually boiled a maximum of 2-3 times, adding fresh water to the kettle. Such boiling is not capable of significantly worsening the taste of water.
