Why can not boil a second time water?

Why can not boil a second time water? - Unfortunately, many do not know the answer to this question, and make a mistake every day without draining the old water from the kettle. But this ban has long been known, but most simply turn a blind eye to it in order to save water and utility bills. In this article you will find comprehensive information on why it is harmful to boil water several times.

Why boil water?

As you know, no living creature can live without water, whether it be a plant, animal, microorganism or person. 80% of our body consists of liquid (in infants - 90%). Fresh water is simply necessary for us for normal metabolism and excretion of toxins and toxins from the body.

Unfortunately, the problem of pure tasty water in the modern world is more than relevant:

• in villages where it was previously possible to find clean springs, now they are no longer completely clean due to soil pollution;
• in the city’s water, to get to the apartment, you need to go kilometers of pipes of dubious purity.

Important! Naturally, in the latter case, the liquid is disinfected with special substances, for example, with bleach, but this spoils the taste and smell of water, and it doesn’t help much. Regarding cleaning systems - their effectiveness is very controversial, because in some cities they have not changed for several decades.

The conclusion regarding the quality of drinking water is deplorable. To at least somehow correct the situation, people began to boil the liquid. The goal of this process is one - to kill all bacteria and microbes that are in raw water, that is, literally sterilize it.

Indeed, most microorganisms die under the influence of high temperatures. Then why can’t you boil the water many times, because the doctors recommend that you use only the liquid that was boiled once to make tea or coffee, be sure to pour out the old remains. To deal with this recommendation, consider the physical and chemical properties of ordinary water.

What happens to water during boiling?

Let us consider in detail what changes occur when the temperature reaches 100 degrees Celsius with the composition of Н2О:

• During boiling, oxygen and water molecules evaporate.
• Since any water contains a large amount of impurities, you should know that after boiling they do not disappear. Moreover, their concentration increases, since the liquid itself becomes smaller due to the evaporation of water molecules. Particles of dirt and salt settle on the bottom of the kettle, forming a white scale.

Important! That is why seawater, even after boiling, is unsuitable for drinking.

• All pathogenic bacteria, viruses and microbes are destroyed.

Important! It is a mistake to think that each subsequent boiling kills an increasing number of harmful microbes, viruses and bacteria. All harmful microorganisms die during the first heat treatment of 100 degrees Celsius.

• Water molecules have heavy chemical elements - isotopes of hydrogen. They are resistant to temperature increase up to 100 degrees and settle to the bottom during boiling. Thus, the liquid becomes more "heavy."

Is it possible to boil water several times?

A large number of people do not drain the old, previously boiled, liquid, and again they boil it to make themselves tea.Is it harmful to boil water a second time? - We will deal with this issue.

Boiled water is completely tasteless.

If a fresh transparent liquid already does not have a special taste, then boiled liquid loses even its remains. And if you boil water several times, then it turns into a very tasteless. To understand the difference, you can conduct an experiment:

1. At some intervals, drink the following fluids: tap water, filtered water, boiled once and boiled liquid several times.
2. All tested liquids will have a completely different taste. And the latter can leave an unpleasant aftertaste.

Boiling makes the water "dead"

The more and more water is treated, the more useless the resulting liquid. When boiling, the chemical formula of H2O is violated, since oxygen leaves the liquid. Water becomes "dead."

The amount of impurities is increasing

With each subsequent boiling of the same liquid, the concentration of salts increases. Naturally, the human body does not immediately feel such changes, and the toxicity of such a liquid is a negligible percentage. But all reactions in "heavy" water occur more slowly, and deuterium, an element that is released during boiling from hydrogen, has the ability to accumulate, which brings undoubted harm to the body.

Important! "Heavy" water looks the same as ordinary water, and has the same chemical formula - H2O, but instead of light hydrogen (protium) atoms, it contains heavy hydrogen atoms (deuterium).

Dogs, rats, mice and other mammalian animals die after about a week of regular consumption of such water due to the replacement in the tissues of more than 25% of light hydrogen to heavy. A person without harm to health can theoretically drink two glasses of “heavy water”. In this case, after a few days, deuterium is completely excreted.

Carcinogens form

As a rule, the water we boil for our food needs is treated with bleach. In the process of heating to 100 degrees Celsius, chlorine enters into a chemical reaction with organic substances, resulting in the formation of carcinogens. This is another of the significant reasons why you can not boil water again. With each subsequent heat treatment, the concentration of carcinogens increases, and these substances are known to provoke the development of cancer in the human body.

How to boil water?

Boiled liquid is already not much useful, but its repeated processing makes it harmful. Therefore, before the following procedure for heating water for tea, follow these simple rules:

1. Each time, use fresh water to boil.
2. Is it possible to boil water a second time? - It is possible, but definitely not necessary! Do not boil repeatedly, as well as add fresh liquid to the processed residues.
3. It is advisable to let the water stand for several hours before boiling.
4. Using a thermos, do not close it with a stopper immediately after pouring boiling water into it. Do it in a few minutes.
5. Watch the container in which boil water. Immediately clean the kettle from scale - you can use citric acid or vinegar to do this.
6. No need to think long about how much water you need to boil. Wait until the water gets a white tint from saturation with air bubbles and turn it off. Do not wait until it begins to seethe and splatter. Remember that the longer the water boils, the less it becomes and the higher the concentration of carcinogens. That is why you can not boil water for a long time.

Important! Boiling for more than 20 minutes completely changes the structure of water.

As you can see, the arguments as to why you can’t boil water several times quite serious. Water and food should only benefit your body. Boil the same water several times or not - it's up to you.But if in this way you can even protect your body from the accumulation of harmful substances by a small percentage, then why not try it? Moreover, special efforts are not required for this.
