Boiling water several times: is it harmful or not?

The question of the harm of this procedure will remain open only because the composition of the water varies significantly in different regions.
Therefore, neither doctors nor sanitary inspection authorities can give a clear answer.
It is necessary to make it clear right away: all this does not apply to water from mineral springs. It is consumed only in its raw form.
Benefits of Boiling
As the environment deteriorates, the chemical composition of water changes dramatically: many foreign harmful substances formed by human and industrial activity dissolve in it.
In this case, boiling is useful, as many of them evaporate at high temperatures. Microbes die. Water hardness decreases.
Such water has a positive effect on the functioning of the body: food is better absorbed, bowel function improves, metabolism becomes normal. Toxins and waste are removed from the body.
The problem of boiling is especially relevant for residents of industrial cities, in which case there is only one answer: "Boil."
Harm
Several times a day, the power button is pressed on the kettle, which is filled with water in the morning. And each time, the water is brought to a boil again. Bacteria are killed more than once a day, but chemical processes are activated, the concentration of toxins increases.
Chlorine begins to interact with already transformed substances, forming a new compound - strong poisons. With each repeated heating, the concentration of harmful substances increases.
Particularly dangerous is the content of arsenic in water, which is not eliminated from the body for years and contributes to the development of many diseases: from cardiovascular to oncological.
When water is boiled repeatedly, fluorine and nitrates are released, which are very dangerous compounds:
— nitrates are everywhere: in the soil, in the air and in water. The threat of their impact increases sharply when they are used as a food preservative (meat delicacies) or at high temperatures. Saturation of the body with nitrates provokes the appearance of leukemia, colon cancer, stomach cancer, bladder cancer;
— Fluorides are especially dangerous for a growing organism. Doctors note that they can lead to neurological disorders and decreased intelligence.
But even the concentration of useful substances during repeated boiling is dangerous for health.
Calcium salts, entering the body in large quantities, cause the appearance of stones in the kidneys and gall bladder.
Everyone should avoid re-boiling water, but especially children, pregnant women and people with chronic illnesses.
You can use water by following these rules:
- let the water stand for 1-2 hours before boiling;
- refresh the water in the kettle before each use;
- regularly descale the kettle.
All this information is useful for those who use tap water.
Nothing bad will happen to the water if it is distilled or has been well-filtered. But you shouldn't get carried away with water that has been boiled more than two or three times.
