Many people believe that boiled water is much healthier than raw. They think that after boiling, you can safely drink it for the benefit of your body. But is this really so? Today more and more often one can hear facts that contradict this opinion. In fact, boiled water does not completely lose all microbes, not to mention herbicides, pesticides, nitrates, metals, petroleum products and phenol. In addition, useful salts such as magnesium and calcium remain on the walls of the kettle after boiling. Thus, it turns out that boiling water only makes it “dead”, eliminating all useful substances and not completely killing all microbes. In this regard, more and more scientists involved in the study of water and its properties recommend drinking raw water directly.
Raw fresh pure water contains many ions of useful trace elements: calcium, sodium, potassium, magnesium and others. Of soluble gases, it contains nitrogen, oxygen, noble gases, more rarely, hydrocarbons or hydrogen sulfide. Due to this composition, water remains “alive” and beneficial to the human body. At the same time, it must be said that “raw” does not mean at all cold from an ordinary tap. This is any non-carbonated drinking water sold in stores, in bottles or just tap water that has undergone thorough purification with a good filter.
It must be said that those who use cleaning filters for water should choose them correctly. It is best to use such devices for such purposes that use a combination of ion-exchange and adsorption technologies, which makes it possible to purify water not only from organic contaminants and residual chlorine, but also from heavy metals.
You should be aware, however, that in some cases, when filters are used, water can, on the contrary, deteriorate and become less useful than just boiled water. Sorption filters pose this danger . In them, water is purified by passing through a sorbent - in most cases it is activated carbon. It collects all the microorganisms and organics, but they must be used regularly. If the filter is not used, for example, for a month, microorganisms, consuming absorbed organic matter, begin to multiply very quickly. Therefore, returning, for example, from vacation, from your tap you can get a whole glass of various microbes. In order to prevent this from happening, it is best to prevent interruptions in the operation of the filter, and if this has happened, rinse it for several hours before further use.
There is another way that allows you to purify water without boiling, leaving all the useful elements in it - settling water. The settling time of water before its use should be 6-8 hours (at least). At the bottom of the dishes, in which water will be purified during this time, all salts, heavy elements, chemical compounds, bleach, etc., harmful to the body, will settle. That is why, when only a third of the remaining water is left in use, it is usually poured out.
Many people find it hard to interpret that boiled water is not as useful as they used to think. However, you can verify this with the simplest example. If you pour boiled water into the aquarium, can fish really live there? No, if only because there will not be even elementary oxygen in it, not to mention other living particles that fish need. So why then should such water be beneficial for the cells of our body?
There is another myth that re-boiling water does not carry any harm in itself, because all the "living" - harmful and useful - is still destroyed. Again wrong. Water molecules contain isotopes of hydrogen. When boiling, the lightest of them leave with steam, and heavy ones settle at the bottom of the kettle. With repeated boiling, the settled molecules become even larger, which makes the water very “heavy”. Therefore, if necessary, water is recommended only to be heated, but not boiled again.
