A hundred years ago, an innovation appeared in the world, without which today we can hardly imagine our lives. But as soon as it appeared, rumors appeared that air conditioning was harmful. And these rumors still concern a significant part of the population. Which of these rumors is true? Is air conditioning harmful or not? However, before dealing with the question “is air conditioning harmful”, it is worth dealing with the problem “do we know how to use it”.

Firstly, the reason why people get sick in an air-conditioned room is mainly their own fault. Don’t forget, the difference in room temperature and outside temperature should not exceed 10 degrees. Our body reacts very ambiguously to large, sharp temperature fluctuations. For the same reason, the air coming out of the air conditioner should not be directed towards a person. In large rooms, it is best to direct the air from the air conditioner along the ceiling. Do not forget that a zone of 2x3 meters is formed in front of the operating air conditioner, where air mobility is high and the temperature is slightly lower than in the rest of the room. The overall temperature in the room should not fall below 20°C, otherwise the microclimate parameters will be disrupted, which can lead to exacerbation of allergic reactions and chronic diseases.

Now let's deal with rumors about the dangers of air conditioning. It is often said that During epidemics, “air conditioning systems for large rooms” can spread viruses throughout the building, that is, deliver each person their own personal microbe. Similar statements were relevant twenty years ago, when many central air conditioners and air handling units had mixing chambers. Now, instead of them, manufacturers install recuperators, and therefore the air supplied and removed from the premises does not have direct contact. As a result, germ-laden air is removed from the room and replaced with fresh air.

The next rumor is that air conditioning is a carrier of such infection as Legionnaires' disease (sapronous bacterial infection, occurring in the form of severe pneumonia with severe intoxication, as well as with lesions of the central nervous system and kidneys). However, the problem is relevant only for some systems central air conditioning, equipped with circulating water supply systems with cooling towers, but in our country there are practically no such systems. But in split systems and window air conditioners, legionella bacteria do not multiply... It prefers a water suspension heated to 30-350C, whereas in household air conditioners The condensate has a temperature slightly above zero and is also immediately removed from the apparatus. That is why not a single case of Legionnaires' disease infection from split systems and window air conditioners has been recorded all over the world.

They often say about the dangers of filters installed on air conditioners, supposedly because of which negatively charged particles - “aerons”, useful for humans, disappear from the air. The air becomes clean, but dead. The statement is very controversial for any person who is familiar with climate control technology first-hand. Most modern split systems and that's it window air conditioners They have only one filter, which is a fine mesh. It prevents the heat exchanger from clogging indoor unit dust, poplar fluff and other debris hanging in the air. It is simply not able to hold back the aerons. Moreover, air conditioners from many companies air filters have a negative electrostatic charge, and therefore cannot capture negative particles at all. Now, if this filter is not changed in due time, dirt from it may begin to enter the premises, and such air will definitely be harmful.

In general, air conditioning is a useful thing. Is air conditioning harmful or do you not know how to use it? - this is the next question. Use it correctly, remember to follow the operating instructions and enjoy clean and cool air in your home and office.

Every person wants to be healthy, energetic, full of strength. Our health depends on many factors, one of the most important is sufficient consumption of ordinary, pure, drinking water. The influence of this natural substance on a person’s well-being and even life expectancy has been scientifically proven. Let's start with the fact that a person himself consists of 2/3 liquid. But if the water that a person drinks daily is contaminated, we are not talking about health and longevity.

Today we will talk to you about a very important topic - about the water that we drink every day, cook food with it, and use it for household needs. Let's find out how water affects health? Let's talk about the benefits when it is fresh, clean, and also learn about the harm when it is contaminated with all kinds of waste.

Water is one of the main elements on our planet, but it is still a little studied substance. It can give life, or it can cause fatal illness. After all, it is known that it dissolves and at the same time accumulates a variety of substances from the soil or atmosphere. When these substances enter the human body, they can cure the disease, or they can poison it.

Benefits of clean drinking water

A person cannot help but drink. Without water, the body will simply die. Therefore, this substance is needed not only to maintain health, it is necessary for human life itself. If he drinks clean, fresh water every day, not contaminated with industrial and organic waste, his health improves significantly and many diseases disappear. Let's list some useful properties:

Weight. It's no secret that water helps you lose weight. It is known to contain no calories. But after drinking a glass, you will fill your stomach, which means that the feeling of hunger will noticeably decrease. Drink a glass of water before lunch and you will eat less food than usual.

Blood pH balance. Pure water improves blood balance as it has a similar pH. This indicator is normally necessary for the normal functioning of important enzyme proteins found in the body. pH balance normalizes all metabolic processes occurring in the body. This, in turn, affects the overall health of a person.

Condition of skin and hair. If your diet contains enough clean, soft drinking water, you don’t need to spend money on expensive cosmetics. Water will keep your skin and hair in a healthy, youthful condition. It is known that the condition of the skin, its appearance, youth and beauty directly depend on its saturation with moisture. The same applies to hair.

Anesthesia. When the body is sufficiently saturated with moisture, muscle tissue becomes more elastic, joint pain is significantly reduced, painful sensations are reduced, negative consequences from damage, sprains.

Detoxification. Water has a detoxifying effect, flushing out toxins, harmful and toxic substances from the body. Helps the body eliminate them naturally.

Harm from contaminated water

Water contaminated with various toxins also affects health. But only in the most negative way. Unfortunately, very often, the so-called drinking water flowing from home taps cannot be drunk at all. In most cases, it is only suitable for technical needs - washing, washing dishes, washing floors, washing, etc. But even spring water, beloved by many, also often does not meet drinking standards. Its quality is affected by the environment and soil contamination with waste.

Its quality is influenced by many factors: waste water from household activities, industry and agriculture. As a result, the water that comes into our house from the tap contains organic microbes, petroleum products, nitrates, and cyanides. It contains salts of heavy metals, chlorine, alkalis, and all kinds of acids.

Of course, during its cleaning, their content is significantly reduced. But what remains can cause negative processes in the body. You also need to know that water is often contaminated radioactive substances, which are almost impossible to get rid of. Therefore, such a substance has the most unfavorable, and sometimes even fatal, effect on human health.

Once in the body, not all of these substances are eliminated. Some of them accumulate and are deposited in cellular tissue. They also remain in the organs and systems of the body, contributing to the development of many diseases. The most simple example may serve as kidney stones, cholelithiasis.

It is most dangerous when water containing toxic substances enters the body. Such water may contain poisons used in agricultural fields or toxic compounds from industrial waste (for example, mercury). This fluid affects internal organs, tissues and systems.

Gradually accumulating, they cause toxic damage, provoke the development of very dangerous diseases, in particular, oncology. And some toxic substances that destroy the body can affect human heredity.

As we have already said, our body is 2/3 water. If it is a pure, healthy substance, a person will live a long time without suffering from disease, and will remain functional until a very old age. Well, if it is dirty, containing poisons and toxins, there is no point in talking about health and longevity.

Therefore, knowing this, try to drink and cook food using filtered or bottled water. Be healthy!

Water is an amazing element without which human body will simply die. Scientists have proven that a person can live about 40 days without food, but only 5 without water. What is the effect of water on the human body?

Structure and main functions of water

By definition from school literature, water is a colorless liquid that has neither smell nor taste. Consists of two hydrogen and one oxygen molecules connected by a hydrogen bond.

Water is the basis of all living things. In the human body, thanks to fluid, all metabolic processes occur. A sufficient amount of water makes the human body healthy, full of strength and energy.

The main functions of the liquid include:

• Metabolism. Water is the main solvent and the basis of many chemical reactions. Liquid may form as an end result.
• Transportation. Water transports molecules between cells and in the intracellular space.
• Thermoregulation. So that the human body does not die when high temperatures, the water begins to evaporate, thereby cooling the body. The liquid distributes temperature evenly throughout the body.
• Excretion. Water helps eliminate from the body final products metabolism.
• Liquid is one of the main components of lubricating secretions, juices and secretions of the body.

It is important to remember that without the required amount of fluid it is impossible to maintain normal water and electrolyte balance. The influence of drinking water on the human body is invaluable, as it takes part in all processes of human life.

Required volume of fluid in the body

The condition of the body directly depends on the amount of water in the body and the age of the person. Thus, dehydration leads to a decrease in fluid absorption; for an adult, the indicator of water shortage is equal to a third of the total volume in the body, and for children - a fifth. A striking example insufficient water is old man. You may notice that his appearance changes, the skin becomes flabby and less elastic.

The percentage of water in the body for a child is 80%, for an adult man - 60%, for a woman - 65%, and for an elderly person - 45%.

Based on this, you need to drink 2-2.5 liters of liquid daily. This amount does not include tea, coffee, juices, sweets and alcoholic drinks. The daily water intake for an adult should not exceed 40 ml/kg, and for a child 120-150 ml/kg.

The positive effect of water on the human body has already been proven by many scientists, so under no circumstances should the body become dehydrated.

Useful properties of water

A person’s health and longevity depend on the amount of fluid in the body. What is the effect of water on the human body? The main advantages are:

• It cleanses the body of harmful substances and toxins. That is why during treatment infectious diseases so good to drink large number water.
• The liquid restores youth to the skin, nourishes it and makes it smooth and elastic. When dehydrated, on the contrary, it begins to peel off and dry out.
• Water helps normalize the gastrointestinal tract and prevent constipation. Due to lack of fluid, a person may feel pain in the abdomen and develop bad smell from the mouth.
• Water reduces the likelihood of cardiovascular diseases. According to scientists, people who drink enough fluids are 40% less susceptible to heart and vascular diseases.
• Water transports necessary elements throughout the body.
• Using required quantity liquids, you can launch the immune system and prevent many viral diseases.
• With the help of liquid, people improve their metabolism and begin to lose extra pounds.

Of course, you shouldn’t overuse water; it’s enough to stick to the norm calculated for your weight and drink it every day.

Negative effects of water on the body

Water will be useful only if it does not contain various chemical elements, harmful substances or bacteria. Therefore, before you start using it, you need to study the composition or prepare melt water yourself.

The positive effect of water on the human body has been demonstrated more than once by many scientists. But what will be the results if you drink “bad” water? This is not talked about very often. So:

• Uncontrolled daily consumption of large amounts of water can lead to kidney and cardiovascular diseases. To prevent this, you need to follow some rules when increasing the volume of fluid consumed.
• You should not drink a liter or more of water at one time. In this case, an extra load is created on the kidneys and the water-salt balance is disrupted.
• You can't drink cold water. This way it lowers body temperature, which can lead to dire consequences. Even in the summer season it is recommended to use warm water.
• Should not exceed daily norm, which is equal to 40 ml per 1 kg of body weight, you should especially not abuse liquids before bedtime. This can cause swelling.

If a person nevertheless decides to exceed the daily norm, then it is necessary to do this gradually, adding no more than 100 ml per day.

Drinking water quality

Water is one of the main products consumed daily, and the impact of water quality on the human body is not taken into account by many. There are four main requirements for water:

To drink truly high-quality water, you need to carefully choose the place where it is obtained. Since not every spring water meets the standards. Source surface waters nearby bodies of water serve.

The best water for consumption is found in artesian springs, the depth of which is at least 100 m. This liquid meets all standards and is safe for people.

Absolutely clean water you won't find it in nature. And there is one in which the level of calcium and magnesium is too high. What is the effect of water hardness on the human body?

Hard water has a bitter taste and negatively affects the gastrointestinal tract. Salts of microelements combine with animal protein, which comes from food, and settle on the walls of the stomach and intestines. Thereby disrupting their functioning, causing dysbacteriosis and poisoning the body. Constant consumption of hard water can lead to joint diseases and the formation of kidney stones, gallbladder.

Drinking mineral water

Mineral water is usually divided into three types - enriched with oxygen, with a high content of silver and iodine.

Most often you can find mineral on supermarket shelves. It is used to treat bronchopulmonary diseases. In addition, it is used for preventive purposes.

Less popular, but no less useful, is mineral water with a high silver content. This is an excellent liquid for combating harmful microorganisms. Distinctive feature of this water is its long-term storage.

Consumption of mineral water with a high iodine content is recommended for people with thyroid diseases.

The positive effect of mineral water on the human body is increasingly being proven by scientists from all over the world. So with its help you can cure diseases genitourinary system, gastrointestinal tract, diabetes mellitus and kidney disease.

However, it is worth remembering that abuse mineral water Instead of improving health, it can lead to the emergence of new diseases and a deterioration in general condition.

Drinking carbonated drinks

Sparkling water is a popular drink, especially in hot weather. This liquid contains useful microelements and prevents infection by dangerous organisms.

Besides positive influence carbonated water has negative effects on the human body, scientists also note negative effects. So, the constant consumption of such drinks containing carbonic acid irritates the mucous membrane, and carbon dioxide, in turn, stretches the walls of the stomach.

Reception of melt water

The first studies of melt water began about 10 years ago. And the results obtained are simply stunning. So scientists come to the conclusion that only melt water is ideally suited in its structure and characteristics to the human body.

What is the effect of melt water on the human body? Drinking such liquid is the key to clean blood, which activates the immune system, regulates metabolism, cleanses blood vessels and lowers cholesterol levels.

To achieve the desired results, you need to drink a glass of melt water daily. To do this, the liquid is poured into a container and placed in the freezer. It is recommended at this moment to think in a positive way or read a prayer. In this way, the water will be positively charged and bring more health to every cell of the body.

Water is the most important component of all living things. Therefore, the health status of each person depends on its quality. You should be careful about the sources of life-giving moisture.

Water is an essential liquid for human internal organs. In the absence of fluid, organs stop working as required, which can cause them to malfunction or even fail.

Today, many people are concerned about how water affects the human body.

Benefits of water

Without water, life could not exist on the planet. Even when it appears in the smallest volumes, the form of existence is reborn. In this matter, man is no exception.

Water facilitates almost every process in the body. It is necessary to move useful substances, restoration of systems, full functioning of organs. IN ordinary life In humans, H2O enters orally, so you need to carefully monitor its quality. Good water is absorbed many times better, which undoubtedly affects metabolism, the functioning of the cardiovascular system, etc.

The effect of fluid on organs and processes mainly depends on age, since changes prevent the spread of fluid. The constitution of the body also plays a big role.

Volume of water in the body

It has been experimentally established that the body of an adult man consists of 60% water. A woman’s body is 67%, and a baby’s is 80%. The human body should receive at least 2 liters of clean water per day, this prevents an increased concentration of toxins. 2 liters is a very subjective figure, because each person has a different body weight. The water requirement for an adult is 40 ml per 1 kg of body weight, for an infant - 140 ml/kg.

Having read the above information, a person should understand that under no circumstances should the body be allowed to become dehydrated. This can lead to metabolic disorders, which subsequently develop into excess weight gain.

Water-bearing foods

You have already seen the usefulness of the liquid. Without it, existence is impossible in principle. It promotes the removal of waste, suppresses toxins, improves metabolism, moisturizes the mucous membrane, and acts as a thermostat. Now it remains to understand what products contain it.

The main water-containing products are: citrus fruits, tomatoes, cucumbers, white cabbage, etc. In a word, water is contained in almost all vegetables and berries. It can also be found in milk, fish and meat.

Basic questions to ask nutritionists

Is it possible to drink water before meals? The liquid fills the stomach, but it cannot saturate the body, since it does not contain any nutrients and calories. In a partially filled stomach, there is less space for food, thereby the feeling of fullness comes faster, and the person eats less.

Should I drink liquid after alcohol? When drinking alcoholic beverages, it is recommended to drink a glass of water in between glasses of alcohol. This action is performed to ensure that the body is full and there is no dehydration, which can lead to disastrous consequences. It is also recommended to drink plenty of liquid after the feast. This will help avoid consequences the next morning.

How much water should you drink in summer? During the warm season, the amount of moisture in the body decreases significantly, as it is excreted in the form of sweat. The consequence of this is usually a deterioration in blood circulation, which, in turn, can lead to the appearance of a blood clot. The amount of fluid consumed should increase in proportion to the temperature increase environment. At temperatures above 30 degrees, a person should drink at least three liters of fluid per day.

When using materials, an active link to

Water is the source of everything that exists on Earth. The human body contains 65% of it, and up to 95% in plants. The human process of digestion, absorption of food and metabolism is not possible without water.

The water spaces of the world's oceans and seas amount to 361 million square meters. km and it occupies 71% of the entire earth's surface.

What properties does water have?

Water is the most mysterious and most widespread substance on the planet. It can be in different states, has many different properties, including memory, which has been proven by scientists. It can behave in the body both as an elixir of life and as its active enemy.

She is truly a mystery and is life itself both for man and for all animals and flora. If a person can live without food for 6 - 8 weeks, then without water he dies already on the 5th - 7th day.

It is a solvent for most organic and inorganic substances. Almost all biochemical and biophysical reactions necessary for metabolism occur in its environment. During a lifetime, a person absorbs 25 tons of water.

With age, the body loses a certain amount water - the body seems to dry out. If the body of a newborn contains up to 90% of water, then in the body of an elderly person only 60 - 65% total weight bodies. The loss of water by the body to a certain extent explains the aging process. If the body lacks only 10% of water, severe poisoning of the entire body and central nervous system occurs.

In its structure, the chemical compound of water is hydrogen + oxygen, more simply H2O. Weight composition = 11.19% and 88.81%. Molecular weight = 18,0153

On Earth in your own way external condition There are three phases of water:

• gaseous (water vapor)
• liquid
• hard

There are waters: atmospheric, surface (or ground) and underground. In nature, water occurs in the form of solutions.

This state of water is good because of its purity; it contains not only salts, but also dirt. However, it is not recommended to drink distilled water all the time, since the absence of microelements and salts in it is unfavorable for the life of the body. Therefore, when you hear about the miracles of healing from the use of distilled water, do not rush to follow such advice.

Scientific studies have shown a direct dependence of cardiovascular diseases on the calcium content in water: the softer the water, the greater the likelihood of cardiovascular diseases.

Electrolysis water

It can be prepared as follows: a vessel with tap water is divided into two parts by a partition made of thick tarpaulin, and an electrode is placed in each compartment, after which a direct current is passed through the system.

When the anodic liquid is saturated with water molecules, it is saturated with oxygen and acquires a certain oxidizing ability (pH reaches 3 - 4 units).

Mineral waters

Waters saturated with mineral salts, biologically active substances and gas have healing properties. They are called mineral. Basic medicinal properties mineral water depend on its chemical composition.

Waters such as Borjomi and Narzan have an alkaline reaction. They normalize motor and secretory functions gastrointestinal tract, reduce dyspeptic disorders. Such waters are useful for diseases of the gastrointestinal tract and genitourinary organs.

With low acidity gastric juice and stagnation of bile in the gallbladder, mineral water containing chlorine ion of the “Essentuki-4” type is useful.

Iodide mineral waters are used for atherosclerosis.

Waters with silicic acid have an analgesic, antitoxic and anti-inflammatory effect.

Ferrous mineral waters: Martialnaya, Jermuk - stimulate blood formation, so it is useful to take them for anemia and blood diseases.

Radon mineral waters are in demand as drinking water, as it has been found that in small quantities they are useful for pyelonephritis and dysfunction of the gastrointestinal tract.

Importance is attached to mineral waters as stimulants of the secretion of intestinal hormones - gastrin and secretin, which are necessary for normal digestion. And yet, mineral waters have a reflex effect on the gastrointestinal tract.

Externally, mineral waters are used for lotions, rinsing, washing, baths, enemas, irrigations, and inhalations. Mineral waters are well absorbed through the mucous membranes and the body locally absorbs from them the salts and minerals it needs.

The composition of sea water and human blood is very close to each other in content chemical elements. There are many substances dissolved in sea water: potassium and magnesium, calcium and iron, barium and chromium, manganese and arsenic, a small amount of silver and gold. 1 liter of Black Sea water contains 11 grams table salt, therefore, sea water when swimming has a beneficial effect on the human body. It helps in the treatment of various rashes, pustular diseases, lichen, itchy skin and eczema.

Sea water is taken internally in exceptional cases, in small quantities and under medical supervision.

Rainwater

The question immediately asked: Is it possible to drink? rainwater? If only it were distilled, many people think so. Yes, this opinion is correct, only if it is clean. It turns out that when an ordinary raindrop weighing 50 mg, falling, washes 16 liters of air along its path. And 1 liter of rainwater absorbs impurities contained in 3000 liters of air. Have you thought about it?

This means that the composition of rainwater depends on the area over which the cloud formed and on atmospheric pollution. Compounds of sulfur and nitrogen, reacting with water in the atmosphere, turn into acids and fall to the ground in the form of so-called acid rain. And nowadays any rain can be “acidic”. That's why:

Not only should you not drink rainwater, you should not even wash your hair or wash clothes in it.

Hard water

This liquid is undesirable for both oral and external use. It is poorly absorbed by the body; a large amount of salts contained in it are deposited in all organs and tissues (joints, blood vessels) of the body, complicating their normal functioning.

In the future, drinking hard water leads to various diseases. It causes irritation of the mucous membranes and increases dry skin.

Soft water

It is better to use soft water for bathing, bathing, washing your hair and carrying out various medical procedures.

It neutralizes the effects of hard water and reduces the harm it causes to the body.

Still water

It is undesirable to use this water, since stagnant water is “dead water” and does not bring any benefit to the body. Standing water causes tumors, intestinal ulcers, various skin diseases, and hemorrhoids.

Melt water

It is for use in medicinal purposes recognized as the best. It is formed as a result of melting ice, therefore, it must first be frozen. During the transition to the solid state, a qualitative transformation of the crystalline structure of water occurs: almost 100% of its molecules are converted into a single type. Think about it, in tap water up to 30 types of varieties of water molecules, divided according to the structure of the crystal lattice.

Melt water can be either “snowy” or “frozen”.

“Snowy” - occurs from the melting of ice and snow, and can be classified as distilled water. It cleanses the body well of salts, nourishes and saturates the body with energy. This water contains few calcium salts, so it rejuvenates cells and promotes longevity. Such water also has a negative property - it is polluted. So you can only drink “snow” water in high-mountain, ecologically clean areas.

“Frozen” is frozen water. Freezing can occur in the refrigerator or in natural bodies of water. Ecologically, it is cleaner than “snow”, but its quality is much worse.

Method for obtaining melt water at home: Place several pots of tap water in the refrigerator. For example, 3 saucepans stand in freezer. Then they take one out, the water in it thaws and it is used immediately, since it has a useful shelf life of only 4 - 5 hours. After this period she becomes plain water, only cleared of dirt that has precipitated. Light and harmful compounds that it rejects from itself float up like a foamy cap when defrosted. Foam and dirt are thrown away.

In old age, drinking melt water prevents a decrease in the water content in cells and streamlines the human biofield, cleanses the body of toxins. It is recommended to take 2-3 glasses of melt water per day immediately after defrosting; its temperature should not exceed 10 degrees C.

You need to drink another glass of water immediately, in one sitting, having first accustomed yourself to drinking it. cold water. The general strengthening effect of using melt water can be noticed within a month after the start of treatment.

Aerated water

To get such water, you need to pour it from one glass to another 35 or 42 times (according to the teachings of yogis). At the same time, the water is saturated with prana and oxygen ions. Water should be poured outdoors or in front of the window. This is done in clear, sunny weather.

When taken orally, the aerated liquid suppresses the pathogenic flora of the gastrointestinal tract and saturates the body with energy. When used externally, it acts bactericidal (due to atomic oxygen dissolved in it) and renews mucous membranes. It is better to use this water in the morning.

Boiled water

Boiled liquid is considered " dead water", since it does not contain organic compounds and she has no memory. Boiled water is recommended to be consumed as food or used for water procedures no later than 2 hours after boiling.

When boiling water, you should never bring the process to a violent boil and then drink it.

It must be remembered that when water is repeatedly boiled, light elements evaporate from it and “heavy” water remains in high concentrations - very harmful to the body.

How much water should a person drink per day - video

This topic about the properties of water is not finished and will be continued in
