Is it possible to boil water several times

What happens to all these substances when water boils? Bacteria and viruses definitely die at the first boil, so this is simply necessary for water disinfection. Especially if the water is taken from a dubious source - a river or a well.

Salts of heavy metals, unfortunately, do not disappear from water, and when boiling, their concentration can only increase due to the fact that a certain volume of water evaporates. The greater the number of boils, the higher the concentration of harmful salts. But, according to scientists, their number is still not enough to cause significant harm to the body at one time.

As for chlorine, during boiling it forms a lot of organochlorine compounds. And the longer the boiling process lasts, the more such compounds appear. These include carcinogens and dioxins that can have a negative effect on the cells of the human body. Scientists, in the course of laboratory studies, have found that such compounds appear even if the water was purified with inert gases before boiling. Of course, the harmful effects of such water will not be noticeable immediately; aggressive substances can accumulate in the body for quite a long time, and then lead to the development of serious diseases. To harm the body, you need to drink this water every day for several years.

According to British woman Julie Harrison, who has extensive experience in researching the influence of lifestyle and nutrition on the occurrence of cancer, every time water is boiled, the content of nitrates, arsenic and sodium fluoride becomes higher. Nitrates are converted into carcinogenic nitrosamines, which in some cases cause leukemia, non-Hodgkin's lymphoma and other types of cancer. Arsenic can also cause cancer, heart pathologies, infertility, neurological problems and, of course, poisoning. Sodium fluoride has a negative effect on the cardiovascular system, and in large doses can lead to sudden changes in blood pressure and dental fluorosis. Substances that are harmless in small quantities, for example, calcium salts, become dangerous when boiling water repeatedly: they damage the kidneys, promote the formation of stones in them, and also provoke arthrosis and arthritis. Repeatedly boiling water for children is especially not recommended, since its high sodium fluoride content can seriously harm their mental and neurological development.

Another fact in favor of the inadmissibility of repeated boiling is the formation of deuterium in water - heavy hydrogen, the density of which also increases. Ordinary water turns into “dead” water, the constant use of which can lead to death.

However, scientists are of the opinion that the concentration of deuterium in water, even after several heat treatments, is negligible. According to the research of academician I.V. Petryanov-Sokolov, to obtain one liter of water with a lethal concentration of deuterium, you will have to boil more than two tons of liquid from the tap.

By the way, water boiled several times changes its taste not for the better, so tea or coffee made from it will not be what it should be!

Is it possible to re-boil water in a kettle?

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, using bottled water is also not recommended, 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 accessible 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 useful 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 gall bladder and kidneys, worsens the microflora in the intestines and the condition of the mucous membranes, and contributes to the occurrence and development of an allergic reaction.

Poor-quality tap water after purification with bleach has an unpleasant taste and impairs the taste of prepared dishes and drinks. Impurities in its composition can easily ruin 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 will go away. But along with these elements, the concentration of calcium and other useful minerals decreases. 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 will be lost, 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, and 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 increased scale formation in the kettle or pan, deterioration in the quality of the laundry after washing, and 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.

To purify the water as much as possible, use special filters or products. For more information on how and how to purify tap water for drinking, see the link https://vsepodomu.ru/uborka/kak-ochistit-vodu-iz-pod-krana/#i-2.

What does repeatedly boiling water do?

Doctors advise using only water that has been boiled once for making tea and coffee. That is, each time the kettle must be completely renewed, pouring out the remaining old liquid before adding new one.

What is the reason for the prejudice against reboiling? Why can't you boil water twice? We will have to touch upon not only the physical, but also the chemical properties of precious moisture.

What happens to the water during heating?

Without water, the human body cannot exist. Eighty percent of our body consists of liquid. Fresh water is necessary for normal metabolism and removal of waste and toxins from the body.

But there are certain problems with water in the modern world. Not every resident of a metropolis can get the required amount of liquid from a well or from a natural source. In addition, we must not forget about the natural pollution of the modern world. Life-giving moisture enters our homes through kilometers of pipes. Naturally, disinfectants are added to it. For example, bleach. If we talk about cleaning systems, their quality leaves much to be desired. In some cities they have not changed for decades.

To use this water for cooking and drinking, people invented boiling. There is only one reason - to destroy, if possible, all bacteria and microbes that are in raw water. There is a joke on this topic:

The girl asks her mother:

Why are you boiling water? So that all microbes die.

Am I going to drink tea with corpses of microbes?

Indeed, most bacteria and microbes die when exposed to high temperatures. But what else happens to the composition of h3O when the temperature reaches 100 degrees Celsius?

1) When boiling, oxygen and water molecules evaporate.

2) Any water contains certain impurities. At high temperatures they do not disappear. Can you drink sea water if you boil it? At 100°C, oxygen and water atoms will be removed, but all salts will remain. But the most interesting thing is that their concentration will increase, since there is less water itself. Therefore, sea water after boiling is not suitable for drinking.

3) Water molecules contain isotopes of hydrogen. These are heavy chemical elements that are resistant to temperatures up to 100°C. They settle to the bottom, “heaviening” the liquid.

Is re-boiling dangerous?

Why do this? The bacteria died during the first boiling. There is no need for repeated heat treatment. Too lazy to change the contents of the kettle? Well, let's figure out whether it is possible to boil again?

1. Boiled water is completely devoid of taste. If you boil it several times, it becomes very, very tasteless. Some might argue that raw water also has no taste. Not at all. Do a little experiment.

At regular intervals, drink tap water, filtered water, boiled once and boiled many times. All of these liquids will taste DIFFERENT. When you drink the latter version (boiled many times), you will even have an unpleasant aftertaste in your mouth, some kind of metallic taste.

2. Boiling “kills” water. The more often the heat treatment occurs, the more useless the liquid is in the long run. Oxygen evaporates, and the usual H2O formula from a chemical point of view is actually violated. For this reason, the name of this drink arose - “dead water”.

3. As mentioned above, after boiling all impurities and salts remain. What happens every time you reheat? Oxygen leaves, and so does water. Consequently, the salt concentration increases. Of course, the body does not immediately feel this.

The toxicity of such a drink is negligible. But in “heavy” water all reactions occur more slowly. Deuterium (a substance that is released from hydrogen during boiling) tends to accumulate. And this is already harmful.

4. We usually boil chlorinated water. When heated to 100 °C, chlorine reacts with organic substances. As a result, carcinogens are formed. Frequent boiling increases their concentration. And these substances are extremely undesirable for humans, as they provoke cancer.

Boiled water is no longer useful. Repeated processing makes it harmful. Therefore, follow these simple rules:

• For boiling, pour fresh water each time;
• do not boil the liquid again and do not add fresh liquid to its remains;
• Before boiling the water, let it stand for several hours;
• Having poured boiling water into a thermos (for preparing a medicinal mixture, for example), close it with a stopper after a few minutes, not immediately.

Why you can't boil water twice: scientific fact

Any thrifty housewife knows that water intended for drinking can be boiled no more than once. However, only specialists in the field of molecular physics and chemistry can explain the physicochemical mechanism of this prohibition. 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 a school chemistry course. It consists of two hydrogen atoms connected to one oxygen atom. The chemical formula of water is 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 correctness of all the scientific facts presented, 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 freezing distilled water, which has a high degree of purification and, from a chemical point of view, is absolutely harmless to humans. It is recommended to use melted liquid for drinking and cooking.

At one time, the quality of water was restored by television charlatan Alan Vladimirovich Chumak, who purified and charged water in front of television viewers, without leaving the Ostankino studio. According to him, neither single nor double boiling was required after this. So why you can’t boil water twice is a scientific fact that explains it quite clearly.

Water is one of the most unique substances in nature. A person needs it every day. An important factor in its use is purity and the absence of harmful impurities. Poor water quality can be extremely dangerous for the body. Therefore, before use, it is usually filtered, frozen or boiled.

What happens to water when it boils?

Each of us boils water. Some use it as drinking water, additionally cooling it. Most people make tea. You can often hear that water cannot be boiled twice. There is an opinion that such liquid becomes dangerous to humans. This is explained by the fact that even with prolonged first heating, beneficial microelements disintegrate. During the second boiling, there is supposedly nothing useful left in the water.

Boiling is necessary in most cases. Harmful bacteria can live in tap water. They die after 2-3 minutes of heat treatment. But it is worth noting that some dangerous microorganisms are not afraid of high temperatures. In this case, boiling is powerless to cope with the problem. Also, this method cannot remove heavy metal salts from water.

It is believed that water should not be boiled twice because it may become “heavy.” From a chemical point of view, this is a myth. Heavy water is almost impossible to create at home. This is a complex process. This result is only affected by long boiling over many years.

In addition, heavy water is not lethal to humans. It is eliminated from the body relatively quickly.

The quality of boiled water may depend on the type of kettle. Many people do not boil water twice in plastic electric kettles. They believe that a reaction is taking place with the plastic. In fact, if a polymer is approved for use as a material in which water is heated, then it is safe.

Highly chlorinated water can be harmful to health. It reacts with plastic already at the first heating. Various hazardous substances begin to be released into the liquid. They can be preserved by repeated boiling. Therefore, the problem is most likely not in secondary boiling, but in the composition of the water. Before heating it in an electric plastic kettle, it must be left in a glass container.

The possibility of harm from secondary boiling can also occur if the kettle is made of low-quality material to which plasticizers have been added. These substances make the plastic less brittle. They begin to release when heated. It turns out that we drink water or tea with a dose of plasticizers. Therefore, you should not buy cheap Chinese devices. Cost is a direct indicator of the quality of plastic. The service life of teapots made of safe material is 3 years. After this, it is better to replace it with a new one.

Boiling water: myths and facts

1. Some explain the harm of boiling by the fact that the structure of the liquid is disrupted. In order to understand this, let us remember such a concept as the memory of water. It means that the liquid remembers the molecular composition of the substance originally dissolved in it. When heated, this memory is supposedly destroyed, and the water becomes dead. Official science does not recognize this fact. The scientific name for dead water is distilled. Essentially, it is a liquid devoid of all impurities. It is obtained using a complex technological process. Like heavy water, it is almost impossible to obtain distilled water at home.
2. Another reason why reboiling is feared is the loss of oxygen in the liquid when reheating. There is less of it in the liquid already during the first heating.
3. Therefore, water quality is important when boiling. Chlorinated water is dangerous both during the first and second heating. With repeated heat treatment, the liquid does not become harder. It is softer than the usual one from the tap.
4. Boiled water will not cause harm to health under the following conditions:
5. Sedimentation or filtration of liquid. Chlorine will evaporate from the water and when heated, carcinogens will not form
6. Proper vessels for boiling. You should not choose teapots made of cheap plastic. When water is heated, a plasticizer is released
7. Cleaning the kettle from scale. This allows you to rid the water of impurities that accumulate on the walls of the dishes.

People living in cities have long been accustomed to boiling water before drinking it. This action is aimed at eliminating various bacteria and microbes that thrive in damp liquid, but are destroyed under the influence of high temperatures.

For many, it is common to boil water once again in order to pamper yourself with another portion of such an aromatic drink as tea or coffee. But this has no meaning. The liquid has already been disinfected by the first thermal treatment and will not become even cleaner from any number of subsequent similar procedures. From a medical point of view, used water should be replaced with new water. Such measures are required for several reasons.

First of all, repeated boiling of water that has already been prepared for use reduces its taste, after which the liquid begins to give off an unpleasant metallic aftertaste.

Even crystal water does not contain impurities - especially if we talk about the chlorinated liquid of cities. The composition of water is designed in such a way that additional exposure to fire will cause only oxygen molecules to evaporate. Thus, the water will become “heavier”, since the amount of liquid it contains will decrease, while the amount of harmful precipitation will remain unchanged.

It is noteworthy that boiling sea water is completely useless - after doing this several times, you will see that the liquid has evaporated, leaving unsuitable salt in its place. Salt impurities are also found in fresh water, but not in such quantities. Other harmful substances are also released - carcinogens, the amount of which directly depends on how much and often the same water is subjected to heat treatment. All these substances do not have an immediate effect on the body, but, accumulating in it over the years, gradually destroy it.

How not to disturb the life-giving power of water

How can you protect your health from the negative effects of water? It is necessary to periodically replace it in the kettle - every time you plan to boil it. You can leave the same liquid, but then you should limit yourself to simply heating it, without bringing it to a boil.

We will have to try to ensure that repeated boiling of water has a bad effect on a person. In order to achieve the deposition of harmful sediments in dangerous doses, it is necessary either to boil it countless times, or to drink the liquid incorrectly prepared for use for a long period of time. But once you approach this issue consciously, water will turn into an irreplaceable friend of your body.

Doctors advise using only water that has been boiled once for making tea and coffee. That is, each time the kettle must be completely renewed, pouring out the remaining old liquid before adding new one.

What is the reason for the prejudice against reboiling? Why can't you boil water twice? We will have to touch upon not only the physical, but also the chemical properties of precious moisture.

Drink for your health!

Everyone knows that every person is 80% water. Its molecules are involved in almost all processes occurring in the body. To ensure normal functioning, each adult needs to drink about 2 liters of liquid per day. In post-Soviet countries, it is generally accepted that boiled water is the cleanest and safest for the human body. But is this really so? In order to answer this question, you need to understand the pros and cons of boiling.

About living and dead water

In its raw form, water contains a large amount of microelements necessary for humans (copper, magnesium, calcium, etc.), present in it in the form of salts. Consuming it in its original, unboiled form has a beneficial effect on all organs and systems of the body and has a rejuvenating effect on it. However, during heat treatment, most salts precipitate, depositing on the bottom and walls of the kettle in the form of a whitish coating that is difficult to wash off.

In addition, during the boiling process, oxygen evaporates from water, and all useful substances present in it are destroyed under the influence of high temperatures. People who prefer to drink such liquid do not get any benefit from it for their body. It is not for nothing that raw water has long been called living, and heat-treated water - dead.

In addition to useful microelements, raw water may contain nitrates, mercury and other substances that cannot be called friendly to the human body. It is useless to boil the liquid to get rid of them. On the contrary, the longer the kettle sits on the stove, the higher the concentration of harmful elements that negatively affect health will become.

Harm of chlorine

Boiled tap water, which city residents use for cooking and tea, deserves special attention. Such a liquid will not only bring no benefit to a person, but can also become dangerous to his health. In our country, it is customary to chlorinate the water entering the apartment through pipes. Thanks to this, it is possible to disinfect it, killing pathogenic microbes in it. But people who are accustomed to drawing water for making tea and food from the tap should know that the chlorine present in it, under the influence of high temperature, becomes a toxic compound that can provoke the formation of kidney stones in a person or even cause the development of cancer.

The harm of boiled water, regardless of whether chlorine is present in it or not, lies in the fact that after heat treatment it is unable to be stored for a long time. After a maximum of 24 hours, pathogenic microorganisms begin to multiply in it, and its consumption can lead to a deterioration in human health.

A few words about the kettle

Boiled water will become truly dangerous if you use a low-quality electric kettle to prepare it. Cheap household appliances today are often made from toxic materials. If you boil water in such a kettle, harmful compounds from the plastic will pass into it, and then, together with tea or coffee, enter the body, causing a person to develop serious illnesses. In order to avoid such troubles, you need to buy kitchen appliances only from reliable manufacturers.

Why is heat treatment necessary?

But why do they always say: “Drink boiled water”? What's good about it if so many facts indicate that heat treatment is harmful? The fact is that raw water, especially if it is taken from the tap, contains many microbes that die at high temperatures. Liquid poured from a kettle that has begun to boil is completely disinfected. You can drink this water without fear of contracting insidious diseases such as intestinal infections, hepatitis, etc. It is undesirable to consume it raw.

The benefit of boiled water is not only that all pathogens are destroyed in it. Heat treatment of the liquid makes it possible to reduce its hardness, which is associated with the high concentration of potassium and magnesium salts in it. When boiled, some of them settle on the walls of the dishes in the form of plaque, which means they do not enter the human body and do not cause the formation of sand and kidney stones.

Basic boiling rules

If you comply with two main conditions, you can drink boiled water without fear that it will in any way harm your health.

Firstly, you don’t need to keep it on the fire for a long time. The kettle must be removed from the stove as soon as the first bubbles begin to appear in the water. This will be enough to kill all harmful microbes in it. At the same time, the absence of long-term heat treatment will help preserve the maximum of beneficial microelements in tea or coffee.

Secondly, under no circumstances should water be boiled again, since as it evaporates, the amount of toxic substances that negatively affect health will increase. The kettle should be filled just enough to last for one time. The remaining water should be poured out of it without regret, and the next time boil new water.

So is it boiled water or raw water?

Today, most doctors are confident that it is best to drink water raw. However, they do not mean the liquid laced with chlorine that flows from the taps of city apartments, but bottled or spring water. If a person drinks water that comes to his home through pipes, then it is necessary to boil it, because heat treatment kills all the microbes in it.
