The harm and benefits of water. Which water is healthier - raw or boiled?

    Opinions vary about which water is healthier, some people think what to drink raw water you can’t 9 because there are a lot of microbes in it) someone thinks that boiled water is dead water. I personally am of the opinion that the most healthy water- melt (although I think she has many opponents)

    If we talk about the benefits for human body, then the palm belongs to raw water - many experts agree on this opinion. ... If you drink boiled water, then immediately turn off the kettle, as... and it is healthier than just liquid from the tap.

    The most healthy water is from proven springs, that is, in other words, living water that contains a lot of mineral salts, such as magnesium, sodium and potassium. But this is not available to everyone. In cities, it is better to drink water by passing it through a filter and preferably boil it until it boils completely. Not It is recommended to boil several times, since the water turns into dead water and the content of dangerous compounds in the water only increases.

    It is also not advisable to drink under-boiled water, since harmful microbes are not destroyed and can harm the body.

    Raw water is definitely healthier. There are only factors that can make it not only harmful but also dangerous. Firstly, these are, of course, microorganisms. Raw water may contain pathogenic bacteria, viruses, protozoa, one of the ways to combat them is boiling, but there are some that can withstand dozens or even hours in boiling water (botulism, hepatitis A virus, etc.). In addition, the water contains salts of heavy metals (copper, iron, lead, cadmium, etc.), which can cause poisoning. Of course, their concentration is insignificant and poisoning will not occur immediately, but they have the property of accumulating in organs and tissues; if water is boiled, their concentration increases. Now there are many different filters, but in my experience most do not give the desired effect, and those that do are very expensive. Now the only option is to buy bottled water, but you need to find a bona fide manufacturer whose water will be of adequate quality.

    Aspirations to healthy image life forces modern man search new ways this is commendable. In general, boiled water is useful and safe only for 2-3 hours after boiling. Because during the heat treatment process, all bacteria in the water are destroyed, both beneficial and harmful. But warm boiled water will create a favorable environment for the proliferation of more serious bacteria. In view of these data discovered by modern scientists, kindergartens have stopped boiling water given to children for drinking, and in fact use modern technologies - various filters. And from myself I can add that you can additionally use homemade filters from activated carbon, shungite stone (sold in pharmacies) - infuse water for several hours; it is also useful to let tap water stand before drinking to reduce the chlorine content in it (after 20-30 minutes, chlorine will decrease by 30-40 percent). As you know, chlorine is not removed from the body on its own.

    The human body is 75 percent water. This is no secret. The condition of our body depends on what kind of water we drink.

    If you have problems with the kidneys or heart, you need to drink raw water very carefully in order to overload the body and not get swelling

    Or if you suffer from rheumatism, gout, diseases nervous system, paralysis, blockage of blood vessels.

    Boiled water warms the body, removes mucus, bloating, shortness of breath, and stops hiccups, but only if it is hot. Cooled boiled water is dead water, all minerals and salts have been boiled down and the cell does not perceive it as water and does not let it pass through the membrane. A person drinks boiled water, and his cells die from dehydration. Water boiled several times, as well as yesterday’s boiled water, will only cause harm to the body.

    In general, of course, raw water is healthier. It is rich in minerals and trace elements. But this is the case if you collected it, for example, from a mountain spring. But in our conditions, even from underground sources within the city or outskirts, one cannot be 100% sure of the purity and usefulness of the water. And I’m generally silent about tap water. So you have to boil it or use expensive filters. Although there are also certain doubts about their effectiveness.

    Water has at least 3 levels of organization:

    • informational;
    • microelement;
    • biological.

    Information. Water molecules are polar (they have positive and negative charges spaced apart in space), therefore they can form complex structures in space (an example of such structures are ice crystals - snowflakes). The closer to freezing point, the more structured water, the closer to the boiling point the more chaotic the water is due to thermal movement molecules. It is believed that structured (information-rich) water has high biological activity; for this reason, for example, the germination rate of seeds soaked in melt water is several times higher than in boiled water. And it tastes like it too cold water more pleasant than hot. Thus, boiling erases the internal structure of water, making it lifeless.

    Microelements. When boiling, hardness salts (calcium and magnesium carbonates) fall out, and these are important macroelements that affect the state of the nervous system, muscle tissue, skin and hair. Therefore, boiled water is inferior in mineralization to unboiled water.

    Microbiology. In unboiled water there are large quantities microorganisms, some of which may be pathogenic. Boiling them kills them, making the water biologically safe.

    Thus, according to two indicators, boiled water loses to raw water, and according to one, it wins. If microbiological contamination is insignificant (spring, well water), then it can be consumed without boiling, as it will bring more benefits to the body. Tap water needs to be boiled, but in general it is not entirely suitable for food purposes; it is more like industrial water. It's not worth drinking.

    There is a myth that you should not add raw water to boiled water and that boiled water several times becomes heavy water. But creating such heavy water will be too expensive and the process will take several decades. So you don't have to worry about this.

    It is necessary to boil water, as this disinfects it and is completely safe for drinking. It does not cause any harm, the only thing is that when boiled, many of it useful elements evaporate.

    The most beneficial is raw spring water, spring water, mineral water from the sources and foothills of the mountains, which contains mineral composition, natural macro- and microelements.

    The ecology in our area is still not what it used to be, so it’s better to boil the water thoroughly, but I don’t drink unboiled water at all, just like plain raw water. There are benefits from such water, but not for drinking.

You can boil water several times, but it is not necessary. The main factor in the benefits and purity of water is not the amount of boiling, but the degree of quality of the original liquid. Therefore, before use, it is important to purify the water using any existing method.

By the way, it is also not recommended to use bottled water, since there is no uniform standard or requirements for the quality of such products. In addition, plastic containers have a negative impact on the contents.

In everyday life, it is better to use standard tap water, but before use, purify it using filters or other available and effective methods. And in this article we will look at whether it is necessary and possible to boil water several times.

Harm from tap water

The water that we pour into the kettle from the tap contains both beneficial and harmful elements. On the one hand, it contains such important substances as calcium and magnesium, oxygen and carbon dioxide. On the other hand, it contains dangerous uranium and barium, bleach, fluorine and nitrates. Such components can cause serious harm and damage to human health.

Regular use of untreated tap water over a long period of time causes the formation of stones in the gallbladder and kidneys, worsens the microflora in the intestines and the condition of the mucous membranes, contributes to the occurrence and development of an allergic reaction.

Poor quality tap water after purification with bleach has bad taste and impairs the taste of prepared foods and drinks. Impurities in its composition can easily spoil the value of tea and coffee.

In addition, tap water is often hard, which deteriorates the quality of clothes after washing. It makes the material rough and unpleasant to the touch, leaving stains and streaks on clothes. To prevent such harm, you need to purify and soften the water.

Boiling to purify and soften water

The benefit of boiling is that it destroys dangerous bacteria and makes the water softer. This is the easiest and most affordable way to cleanse at home. If you boil water for 15 minutes along with steam, harmful chemical compounds. But along with these elements, the concentration of calcium and other useful minerals. At the same time, bleach and non-volatile substances remain in the composition. In boiled water they turn into more dangerous carcinogens.

The longer and more you boil water, the more useful substances goes away, the more useless it will become. In addition, after boiling, salt deposits and stains remain on the walls of the dishes, and scale forms. At the same time, the level of dangerous pollutants in the water is low enough that it will not cause serious harm to health.

If you use an electric kettle, it turns off quickly and the boiling time is short. Therefore, repeated or even repeated boiling will not be harmful. However, many experts still do not recommend repeating this procedure and consider it unnecessary. Let's figure out why you can't boil water twice.

Is it possible to boil water twice?

It is not recommended to boil water again. With repeated and subsequent boiling, harmful elements turn into carcinogens that are dangerous to humans. This can lead to cancer and neurological diseases, problems with the heart, loss of vascular elasticity, impaired development and growth of children.

Note that the danger lies not in the number of boils, but in the duration of the procedure. The longer the water boils, the more active the production of negative and harmful substances.

With prolonged and repeated boiling, the hydrogen isotope settles and deuterium is formed. It disrupts material metabolism in the body and impairs the absorption of vitamins. This is a scientific fact that explains why you should not boil water twice.

In addition, boiled water takes on an unpleasant taste. And with each new boiling it gets worse. The reason for this process is that harmful impurities in water at a temperature of 100 degrees react and become active, as a result they give an unpleasant taste.

Six reasons why you shouldn't boil water again

  1. After you boil water in a kettle, especially repeatedly, it first loses its taste and then acquires an unpleasant aftertaste;
  2. When heated to 100 degrees, chlorine interacts with organic substances, which forms carcinogens that are harmful to the body and human health. Each subsequent boiling increases the concentration of the latter;
  3. The more often heat treatment occurs, the more beneficial substances and properties the water loses. As a result, it becomes useless and “dead”;
  4. When reheated, oxygen leaves, water evaporates, and the content of salts and impurities increases. Such water is no longer suitable for preparing broths and soups, tea and coffee, or cooking pasta;
  5. If after the first boiling the water becomes softer, then after the second and subsequent boiling it becomes heavier. This will lead to advanced education scale in a kettle or pan, deterioration in the quality of linen after washing, the taste of cooked food and drinks;
  6. When water is boiled again in a kettle or other container, a hydrogen isotope called toxic deuterium precipitates. It gradually accumulates, which is dangerous to human health.

How to purify tap water

To get high-quality, healthy and tasty water, it is enough to settle the contents before use. Half an hour is enough for the harmful chlorine to disappear. Before boiling, it is better to stand for several hours so that harmful gases and compounds evaporate. If you pour the contents into a thermos, leave it open for a few minutes and only then close the lid.

For each boil, it is healthier and safer to use new, fresh water. Do not boil the liquid again and do not add fresh water to the water that remains after the previous boiling. To make tea or coffee, boiled water can be slightly heated without bringing the liquid to a boil again. Do not do this in the microwave as it kills all the beneficial elements.

Without water, as is known from the song for the Soviet film, “neither here nor here.” Indeed, without it there cannot be life itself. Thanks to the inventors of plumbing for the fact that people no longer have to think about how water gets into the house. But, alas, quite often tap water leaves much to be desired in terms of quality and purity. There can be many reasons for this state of affairs - from worn out pipes to the characteristics of local sources.

Why do you need to boil water?

One of the significant disadvantages of tap water is rigidity, that is, an increased concentration of calcium and magnesium salts. Hard water negatively affects the condition of human skin and hair, forms limescale on dishes and household appliances, makes it difficult to rinse clothes, spoils the taste of tea and coffee and, in general, is not very good for health. To be fair, it should be noted that complete absence salts - not much better; moderately hard water is optimal for the body.

It is also polluted by various impurities- nitrogen compounds, iron, manganese ions and others. Most often, this is due to the insufficient quality and functioning of treatment facilities.

Brings controversial benefits chlorination. On the one hand, it is the cheapest and safe way disinfection, and on the other – deterioration of its taste and quality. Not to mention the reaction of chlorine with organic compounds, which can form dangerous cumulative carcinogens.

Yet, contrary to popular belief, tap water is not so bad. Most of the impurities are contained in small quantities and are practically harmless. At the very least, no one has canceled state control over quality.

But at the same time, sanitary doctors are unanimous that under no circumstances should you drink water directly from the tap. You need to at least boil it.

What happens when it boils

From the point of view of physical science, boiling is a process of vaporization that occurs from the surface of a liquid and inside it. In the volume of water, boundaries of separation of different phases (liquid and vapor) are formed, thus creating bubbles, by which we can “by eye” determine that the water has boiled. Boiling of any liquid can only occur at a certain temperature, for water this is + 100 0 C.

Externally, one can observe three stages of the process of boiling water in domestic conditions.

  • Single small bubbles begin to appear from the bottom of the kettle or pan, the number of which gradually increases; the bubbles are grouped on the surface of the water closer to the walls of the dish.
  • Massive rapid rise of bubbles, causing first a slight cloudiness and then some whitening of the water. This stage of boiling is called “white spring” because it resembles running water from a spring. By the way, true tea connoisseurs believe that it should be brewed with water at exactly this stage, without bringing it directly to a boil.
  • An intense bubbling process, during which large bubbles burst on the surface, steam is actively released, and water begins to splash out of the dishes.

The harm and benefits of boiled water

If the water is not purified using filter systems, boiling becomes prerequisite its consumption. The biggest advantages of this cleaning method are its absolute simplicity and accessibility.

Of course, boiling gets rid of most harmful impurities. In the process, a significant part of the bacteria dies, organochlorine compounds are destroyed, and the water becomes softer and more pleasant to the taste. But it is not able to completely replace correct cleaning with filters; in addition, this process also has some disadvantages.

Firstly, quite strongly chlorinated water flows from the tap, in which, when boiled, dioxin is formed - a global ecotoxicant that has a carcinogenic effect and the insidious property of accumulating in the body. Even in minute concentrations, dioxin can cause genetic cellular changes.

Secondly, regular boiling does not destroy all pathogenic microorganisms contained in water. Moreover, it does not eliminate impurities of heavy metals, pesticides, herbicides, nitrates, petroleum products and other “chemicals”. With prolonged boiling, the concentration of heavy metal salts increases due to evaporation, which is clearly demonstrated by the scale formed on the dishes.

Thirdly, boiling destroys the structure that the human body becomes best case scenario useless. There is such a concept - heavy water, in which hydrogen atoms are replaced by deuterium atoms (a heavy isotope of hydrogen). Negative Impact on the body has been confirmed by numerous experiments. The well-known “dead” water from the Russians folk tales- this is heavy water. During the boiling process, a certain amount of heavy, “dead” water is formed.

"Optimization" of the boiling process

If you follow the following simple rules, you can, while maintaining the disinfection effect, minimize harmful effects boiling.

Any thrifty housewife knows that water intended for drinking can be boiled no more than once. However, the physicochemical mechanism of this prohibition can only be explained in the field of molecular physics and chemistry. Despite the preservation of the organoleptic characteristics of the liquid during the boiling process, its structure and composition of substances change. Why you can’t boil water twice is a scientific fact confirmed by experiments. This phenomenon is caused by several reasons.

Physico-chemical characteristics of water

The structure of a water molecule is known from the course school chemistry. It consists of two hydrogen atoms connected to one oxygen atom. Chemical formula water H2O. The liquid is colorless, transparent, tasteless and odorless. Tap and natural water (river, lake, spring) contains many dissolved mineral chemical impurities, most of which are harmful to the human body. In addition, natural water contains complex high-molecular organic compounds, microflora and microfauna.

Why you can't boil water twice - this is a scientific fact

The main purpose of boiling water is to destroy harmful and pathogenic microorganisms that die when the temperature of the liquid increases.

Without denying the truth of all the above scientific facts, a completely legitimate question arises - why can't you drink distilled water? ? There are no prohibitions here, but it has been noted that the distillate, which has neither taste nor smell, also negatively affects human health. Moreover, there is no consensus among scientists about the reasons for this phenomenon. According to some scientists, in distilled water, which has gone through the steam stage and then condensed again, the direction of the charge changes and the magnitude of the dipole moment changes. To restore its original properties, some healers recommend distilled water, which has high degree cleaning and, from a chemical point of view, absolutely harmless to humans, freeze. It is recommended to use melted liquid for drinking and cooking.

Hello, Oleg!

Please tell me, how will it be for your health if you constantly drink boiled water?.. We live outside the city, the water is from a spring, they usually drink it here like that, they say it’s good, but we boil it just in case, and then we drink the cooled boiled water. Isn't this harmful? How does this affect human health?

Boiling- the process of bringing water to its boiling point for the purpose of water purification and disinfection.

When water is boiled, chlorine and chlorine-containing compounds are destroyed, colloidal particles of impurities and salt precipitate, scale forms, the water is softened, the content of volatile components in it decreases, pathogenic microbes, dangerous bacteria, viruses and pathogens are destroyed.

Therefore, boiling really helps to purify water, but this process has a number of side effects:

1 – when boiling, the structure of water is destroyed, i.e. she becomes "dead". Therefore, the more we boil water, the more it becomes useless, dead water for the body.

2 - since water evaporates during boiling, the concentration of salts in it increases. They are deposited on the walls of the kettle in the form of scale and lime and enter the human body during subsequent consumption. Salts tend to accumulate in the body, leading to the most various diseases, ranging from joint diseases, the formation of kidney stones and ending with arteriosclerosis, heart attack, etc.

3 - some bacteria and viruses can easily tolerate boiling water, since it takes much longer boiling time to kill them. So, to destroy some bacterial spores, you need to boil water for at least 10 minutes. Yes, the pathogen viral hepatitis dies when more high temperature boiling, prions - the causative agents of “mad cow disease” - do not die even when boiled for a long time.

4 - when boiling water, chlorine is not completely removed, but interacts with other organic compounds in the water, forming trihalomethanes that are dangerous to the body - more harmful and dangerous than the original chlorine.

5 - along with chlorine, oxygen also evaporates during boiling.

6 - it is impossible to remove iron salts, cadmium, mercury, and nitrates by boiling.

According to scientific researchers, constant use boiled tap water can lead to decreased immunity. After several hours after boiling, it begins to actively multiply somewhere in the boiled water. bacterial microflora and the water becomes bacteriologically dangerous due to microorganisms introduced from the air.

Therefore, tap water must be purified before use. Most reliable way– filtering through activated carbon or ceramic filters. Better yet, do melt water. After thawing, it changes its structure and is completely renewed. Then the water becomes environmentally cleaner and can be drunk even raw.

But you can boil water from a spring, since it does not contain chlorine added to water at water treatment plants. Therefore, the health risk in this case is minimal. But when using boiled spring water you must realize that its original natural structure has been disrupted.
