Why can’t you boil water in a kettle twice?

The World Wide Web is full of headlines that running water cannot be boiled twice. But why? Indeed, logically, double or triple boiling of a liquid is guaranteed to kill the harmful microorganisms that are in it. In practice, the situation is somewhat different - it is not only a matter of microorganisms.

From the point of view of science

Chemistry will help us understand this issue. Water is not just a combination of two hydrogen atoms through one oxygen atom. It is also an environment inhabited by many beneficial and harmful microorganisms. Unfortunately, even cleaning the liquid at a high technological level does not guarantee the complete absence of microflora at the outlet.

What happens to running water if boiled a second time:

• If at the first boiling of the liquid the number of harmful microorganisms rapidly decreases in it, then at the second boiling the organic component decays, which can adversely affect human health.
• Scientific fact: hydrogen atoms are partially split and, entering into a bond with other harmful elements, settle to the bottom of the container or dishes, thereby gradually increasing the density of the liquid.
• If you boil water more than once, then the beneficial substances contained in it decompose. Instead, they form (in small quantities) harmful compounds such as fluorine and arsenic. Or, for example, nitrates, which under the influence of high temperatures cease to be safe additives and turn into harmful nitrosamines.

As can be seen from the above arguments, if you boil water 2 times, then this will only exacerbate its harmfulness. Even a high degree of purification at the station cannot guarantee full safety of the aquatic environment.

Is distilled water good or bad?

Many “experts” in the field of water purification are often advised to use distilled liquid. It seems like its beneficial qualities do not disappear even after a few boils. But is it?

Distilled water, having gone through the stages of evaporation, cooling and condensation, receives simultaneous saturation with oxygen and carbon dioxide (as well as a number of other substances). With an increase in the level of carbon dioxide in a liquid, the aqueous medium acquires slightly acidic qualities. If distillation is carried out several times, the water will become completely neutral (this is used for technical purposes, for example, for refueling batteries).

Reasons why you should not drink distilled water:

1. Its pH is several units lower, which negatively affects the metabolism.
2. Minerals that are needed for normal nerve conduction, for renewing body tissues and maintaining hormonal levels are not dissolved in it.

Is distilled water harmful or beneficial? It’s definitely harmful, because if a person often drinks distilled water, he doesn’t get the necessary minerals, so he develops first kidney disease, and subsequently other pathologies.

How to get rid of the unpleasant effects of boiling?

It should immediately be said that even the initial boiling of a liquid is not entirely useful. The process of heating water leads to the destruction of bacteria and to a more active movement of impurities that can settle for a very long time. But, applying simple tips in practice, you can, if not completely get rid of the harmful effects of boiling, then at least minimize it.

• Before boiling the liquid, let it stand in a clean tank for at least two or three hours. Even if she had gone before than a system of super-efficient filters.
• Close the lid of the brewing tank, immediately after adding boiling water, is not recommended. A greater flow of oxygen will neutralize some of the harmful impurities on the surface of the hot drink.
• Never mix hot boiled water with cold. Many people like to cool their drink in this way, but in reality they only add a fresh portion of harmful microorganisms to it.

And the main advice: after the first boil, change the water in the kettle. Such a useful habit allows you to not boil the liquid several times.

Do not boil - freeze

If you use boiling as a cleaning method, then it is better to pay attention to a more effective way. The Internet is filled with articles that advise you to clean the liquid by freezing. And this option is suitable, even if you take chlorinated water from the tap. The most interesting thing is that this is not a myth; freezing really allows you to get rid of harmful impurities.

After the water turns into ice, a small amount of liquid will remain at the bottom of the tank, which must be drained. According to experts, this is light water, poorly absorbed by the body. Defrost ice and drink cool water with pleasure. A great option for storing bottled liquids.

In conclusion, we recall: many diseases begin due to a lack of fluid in the body or with its low quality. Remember that clean water without impurities is the basis of a person’s long life and good health.
