The role and importance of water in human life. The role of water in the human body (daily rate and properties)

TOPIC: UNIQUE ROLE OF WATER IN LIVING MATTER

Introduction

Water, you have no taste, no color, no smell. You cannot be described, you are enjoyed without knowing what you are! This is not to say that you are necessary for life: you are life itself. You are the greatest wealth in the world.

Antoine de Saint-Exupery

Water is vital. It is needed everywhere - in everyday life, agriculture and industry. The body needs water for to a greater extent than anything else except oxygen. A well-fed person can live without food for 3-4 weeks, and without water - only a few days.

A living cell requires water both to maintain its structure and to function normally; it is about 2/3 of body weight. Water helps regulate body temperature and serves as a lubricant to facilitate joint movement. She plays important role in building and repairing body tissues.

With a sharp reduction in water consumption, a person becomes ill or his body begins to function worse. But water is needed, of course, not only for drinking: it also helps to keep a person in good hygienic condition his body, home and environment.

Personal hygiene is impossible without water, that is, a set of practical actions and skills that ensure the protection of the body from diseases and maintain human health at a high level. Washing your face, a warm bath and swimming bring a feeling of vigor and tranquility.

About water in general

Much has been said about water, but little has been said. Therefore, the phrase "Water is life" for many of us does not mean anything evenly. And water takes cruel revenge on us for the careless attitude towards it. Think about what you know about water? Surprisingly, but water is still the most poorly studied substance Nature. Obviously, this happened because there is a lot of it, it is omnipresent, it is around us, above us, below us, in us. Water is considered the most difficult of all substances studied by physicists and chemists. Chemical composition waters can be the same, and their effect on the body is different, because each water was formed under specific conditions. And if life is animated water, then, like life, water has many faces and its characteristics are endless.

At first glance, water is a simple chemical compound of hydrogen and oxygen. But in fact, water is the basis of life on Earth.

Water is a universal solvent for a significant amount of substances, and therefore there is no chemically pure water in nature. According to the content of substances dissolved in water, water is divided into 3 classes: fresh, salted and brines. Fresh water is of the greatest importance in everyday life. Although water covers three quarters of the Earth's surface and its reserves are enormous and are constantly supported by the water cycle in nature, the problem of providing water in many regions of the world has not been resolved and is becoming aggravated with the development of scientific and technological progress. About 60% of the Earth's surface is made up of zones where there is no fresh water or there is an acute shortage of it. Nearly 500 million people suffer from disease caused by deficiency or quality deficiency drinking water... Fresh water accounts for about 2% of all water resources on the planet.

By 2050, 4.2 billion people will live in countries where it is already impossible to meet the daily human need for water - 50 liters per day (data from the UN report on population). The number of earthlings, which has doubled over the past 40 years, is now 6.1 billion and may double by the middle of this century. The main growth is expected in developing countries, where resources, in particular water resources, are practically depleted. Now people use 54% of the available fresh water, and two-thirds goes to the needs of agriculture, according to the “Green Dossier.” According to experts, by 2025 water consumption will increase to 75% of the current level only due to an increase in population. Already, more than a billion earthlings do not have access to clean water. The problem is that in developing countries, 95% of sewage and 70% industrial waste discharged into water bodies without purification.

Water itself has no nutritional value, but it is an indispensable part of all living things. In plants - up to 90% of water, and in the body of an adult - about 65%; this circumstance allowed the science fiction writer V. Savchenko to declare that a person “has much more reason to consider himself a liquid than, say, a forty percent solution of caustic soda”.

A definite and constant water content is one of the necessary conditions for the existence of a living organism. When the amount of water consumed and its salt composition changes, the processes of digestion and assimilation of food, hematopoiesis are disrupted. Without water, it is impossible to regulate the body's heat exchange with the environment and maintain a constant body temperature.

A person is extremely sensitive to changes in water content and can live without it for only a few days. With a loss of water up to 2% of body weight (1-1.5 l), thirst appears, with a loss of 6-8%, a semi-fainting state occurs, with a shortage of 10%, hallucinations appear, swallowing is impaired. With a shortage of more than 12% of water, death occurs. (We advise you to read our article "Drinking regime and water balance in the body").

Average daily water consumption - 2.5 liters. Excess water overloads the cardiovascular system, causes exhausting sweating, is accompanied by loss of salts, weakens the body. Very important mineral composition water. A person uses water for drinking, containing from 0.02 to 2 grams of minerals in 1 liter. Substances in small doses, but playing an important role in many physiological processes of the body, are of great importance. For example, long-term consumption of drinking water containing less than 0.6 mg / l of fluoride leads to the development of dental caries.

The content of carbonate and sulphate salts of calcium, magnesium and iron determines the hardness of the water; with a small amount of them, the water is considered soft, and with a significant amount - hard. In hard water vegetables and meat are poorly boiled, because calcium salts with proteins food products form insoluble compounds. At the same time, the food is absorbed by the body worse. Tea in hard water is poorly infused and its taste decreases.

Very hard water is unpleasant for washing, and when washing clothes in such water, consumption increases detergents... At home, hard water softening is achieved by boiling.

If causative agents of infectious diseases (cholera, typhoid fever, dysentery, etc.) get into drinking water, it can be a factor in their spread. Causative agents intestinal infections remain viable in water for a long time. For example, typhoid fever can persist in river water for over 180 days.

So what do we know about water? Is water just a chemical combination of two hydrogen atoms with one oxygen atom?

The role of water in wildlife.

The most classic expression in relation to water - water is Life, in essence and in essence accurately reflect the state of affairs!

However, everything "revolves" around the bush when it comes to the true position of water in living matter ... There are a lot of guesses, research results have accumulated, but the time has come to reduce all research and facts to a single law about water in Nature and living matter in particular.

It makes no sense to list the unique properties of water, because almost all of its properties have been studied at the physical, metaphysical and informational levels.

(The last statement is not recognized by modern science!) It would seem that everything….

However, studying ancient and modern sources about water, you come to the conclusion ... that water is practically inexhaustible .... In no sense ...

It is known that the most interesting events and strange phenomena. This applies without any reservations to the physics of surfaces, boundary layers of solids, plasma, liquids and gases ... Water is no exception at the interface between media, and at the surfaces with which it comes into contact. The role of water in photosynthesis is still unknown, but the process of cognition is moving in the solution of this phenomenon. It is also “involved in geometry ...

"Neither water, nor ice" existing on the boundary "liquid - solid", or the so-called mixed region. Physicists claim to have discovered

the existence of mixed ice-like and liquid-like regions at the water-quartz interface; with different polar orientations corresponding to water molecules, which pointed either oxygen or hydrogen ends to the surface of a solid. For the first time, scientists were able to determine the spatial orientation of individual molecules in the thinnest layer of water adjacent to quartz. This is the boundary layer of water! For example, that in this place (a layer only a few molecules thick) some of the water molecules form ice-like rigid structures (despite the fact that the water temperature is normal, room temperature). In liquid water, hydrogen bonds of several neighboring molecules form unstable, very fleeting structures. In ice, each water molecule is rigidly bound to four others. Such a phenomenon was only hypothesized theoretically, but until this moment it was not confirmed.

experimentally. A similar phenomenon was found in quatarons ... Scientists also found out that the orientation of water molecules in this boundary layer may depend on the acidity of the medium. "In membranes reverse osmosis capable of separating water from salt ions or other impurities, the pores of the materials are so small that only water molecules can pass through them. In such cases, the behavior of water within just a few molecular layers is very important for determining the capabilities of the membrane. ”This will allow ultrafilters to be created without negative and positive pressures.

For artificial kidneys. Water in the body is not only in solid, liquid state, but also in the quantum-gel and superionic state. In the so-called superionic phase state, oxygen atoms in water are firmly frozen in crystal lattice, but hydrogen atoms remain mobile, like in a gas, traveling freely throughout the crystal at a very high speed. The surperionic state was predicted earlier. Physicists speculated that in this form water exists in the depths of the giant planets: at a temperature of a thousand degrees Celsius and a pressure of one hundred thousand atmospheres. Physicist Fried tried to reproduce superionic water in a laboratory by squeezing ordinary water between diamond anvils and simultaneously heating it with an infrared laser. What we actually have in the body during cavitation, autowave oscillations, and in the anti-node of a standing wave. By taking data on the vibration of water molecules, the researchers could see that their phase state changed to something unusual. But, having caught this border, the experimenters could not say for sure what exactly is happening on the other side of it. To do this, they needed a supercomputer and a week of computer time. Fried and his team calculated the behavior of 60 water molecules under such conditions and found that they break down, and the atoms that formed these molecules actually form a superionic phase - denser than ice, solid like iron, but which is neither ice nor liquid or gas in the usual sense. The high electrical conductivity of superionic water can be responsible for powerful magnetic fields Uranus and Neptune, the researchers added. We must also assume for the bioenergy of living organisms. The degree to which water participates in photosynthetic processes is terra incognita. Having solved this problem, we will solve the problem of cancer treatment and energy of biological systems. Chloroplasts have what are called thylakoid membranes. Huge groups of complex proteins are attached to these membranes. There are two such groups - "photosystem I" and "photosystem II" (PSI and PSII). And in the depths of PSII is the OEC complex, without which photosynthesis would be impossible - this is a kind of needle that modern biologists have never reached. What does this needle do? It splits water into oxygen molecules, hydrogen ions and free electrons using the energy of light. This is where we come to the forefront of photosynthetic research - how exactly the OEC turns its focus and how the complex itself looks. A lot is already known. For example, the composition of the complex - it is based on four manganese ions, one calcium ion, and several oxygen atoms (not those that we will "create" by decomposing water, but internal, irreplaceable). But, alas, their mutual arrangement, as well as the details of interaction with light and water, have not yet succumbed.

The creation of an oxygen molecule takes several steps. In this case, the OEC acts as a capacitor - it accumulates charge in stages, so that it can then be discharged in one jump and direct this energy for the synthesis of oxygen. Are these not signs of crystals, changes in their symmetry and phase state? The complex has five states - from S0 to S4. In S0, two out of four manganese ions have a positive charge of four units (these are MnIV ions), while the other two ions have a charge of plus three (MnIII) and plus two (MnII), respectively. The first three steps (from S0 to S3) are the sequential capture of light quanta with the release of electrons, as a result of which the complex turns into a set of one MnIII and three MnIV (plus, of course, oxygen and calcium). In this case, one of the oxygen atoms from the complex also loses an electron. What's next is unknown. It is only clear that there are two more steps - S3-S4 and return: S4-S0. As a result, the complex jumps to its original state, and the water entering the limits of photosystem II decomposes into neutral oxygen and a hydrogen ion.

The electrons released during all these steps are transported to the neighboring protein system PSI, where they participate in a long chain of biochemical reactions leading to the absorption of carbon and the growth of the plant. How exactly the complex splits water and forms a bond between two oxygen atoms is still a mystery. It is surprising that we are talking only about finding the mutual arrangement and the mechanism of interaction of several atoms in the OEC complex - in fact, in a single molecule with chemical formula Mn4O4Ca. Calculations using silver as an example show that as a result of a recently discovered effect (changes in energy and chemistry at the interface between media), surface oxidation can begin at an oxygen concentration thousands of times lower than previously thought. Even the thinnest oxide film with a thickness of several molecules can greatly affect the ability of the plate to deposit gas molecules on itself, and therefore change the catalytic properties of the sample. The author of the discovery notes that the described effect is not at all obliged to be limited to oxides, that is, the combination of a metal with oxygen. The same arguments in certain situations apply to thin films of nitrides, hydrides, etc. and one must assume proteins in the allotropic phase and water in the superionic state. As it turned out, this phenomenon is very similar to the effect of surface melting. The same takes place during the formation of water quatarons ... In general, the phenomenon is perfectly illustrated by the fact that thermodynamic and chemical transformations on the surface can be very different from the "three-dimensional" laws we are used to. Considering these facts, it can be assumed for now that gases, guest molecules, and water molecules in a superionic state should interact differently with the cellular and film structures of normal and cancer cells. And, most importantly, water molecules in a similar state entering the photosystem accompany all five states - from S0 to S4. Now all that remains is to connect these three mechanisms and the solution to photosynthesis is not far off. Well, there is not far to the creation of artificial living matter ...

Water is described in many medical schools as a remedy ...

Let's start with pharmacology. In Tibetan medicine (which in fact was born in the BO religion, ie Tengrianism) there is a wonderful expression: "Boiled water - standing overnight, becomes poison."

"Melt water - heals everything ..." and so on. Many treatises have been written about medicinal properties water, but modern pharmacology and medicine divert water for the purpose of therapy, a modest place, calling it water load, drinking regimen. At the same time, it does not say at all what water to drink (with the exception of medicinal and table water) ... It will be about the water that is recommended inside. This does not apply to balneology, water treatments and spa treatments. This is an unforgivable gap in modern pharmacology and medicine!

Mortality from drug therapy is currently ranked 5th among violent and disease-related deaths. The first place is firmly entrenched for cancer ...

Pharmaceutical concerns produce up to 10,000 names of drugs ... Traces of hormones and antibiotics are found in deep groundwater and the stratosphere ...

Even among the people it has long been known that most body systems are completely independent of the way of life! For people leading the wrong lifestyle, or rather, in the general sense, an unhealthy lifestyle does not cause any deviations. And vice versa! Why is there such a paradox? Just because living matter is not what biologists and physicians have in mind…. Rather, the laws by which living matter exists are more universal and simpler than it seems to us ...

The model of living matter proposed by me many years ago finds more and more confirmation in various sciences, and above all in physics.

Living matter is primarily a simple physical object. This object is subject to all physical laws, but it also has its own properties that lead it out of the world of inanimate nature! Moreover, there is practically no border as such between living and non-living !!! This is a contrived border….

So, organic living matter is based on proteins and water. Moreover, water represents a seemingly silent majority. However, this is not at all the case! It is unacceptable to think that the waters of organisms and water external environment This is the same! Not in the metaphysical, but in whatever is in physical sense this word. The properties of water molecules that have entered the body from outside are radically different from external water. Let's ask a simple question. And what so radically changes the properties of water? These are proteins and amino acids ... Amino acids of all known substances on Earth have the most adhesive properties in relation to water molecules ... Especially left-handed polarized ones. That is why, when water evaporates (dehydration) on the adhesive surface, amino acid molecules are combined into proteins, which in turn are formed into fractal structures, which we call primary, secondary, ternary, and quaternary spatial structures of a protein.

Professor M. Kutushov described pentary and sixfold structures, which are called "cells-domains". The principle of automorphism or homomorphism says that the initial clusters of water have such a domain structure. When the molecules of amino acids and proteins, water molecules, bordering on molecules, move during evaporation, at the moment of phase transitions, epitaxial forms are formed, and a little further away, heteroepitaxial forms of water are formed. In the body, the process of "dehydration" is undulating, unidirectional and constant, which is why everything works in sync with the body!

And the most important thing! At the moment when proteins pass into an allotropic phase state (this is described in detail in all my books) water molecules also change their spatial conformation, becoming allotropic or vital ... This form of water is the same living water... Rather, at the moment when the phase states of protein and water molecules coincide, a standing wave (soliton) is formed. Those. the same matter that is simultaneously matter and free energy, which everyone calls bioenergy.

The nature of this wave is electromagnetic and magnetic. Now let's get back to water, but with new knowledge. Physicists studying hydrodynamics drew attention to the fact that when solids move in water in the boundary layer, the properties of water change nonlinearly ...

According to physicist S.E. Postnova in the boundary layer, which behaves like an autonomous object, there are few particles, a nonlinear change in the electric potential - the internal water of the body has exactly the same properties! Question. What kind of conditions are created by substances with the same properties? According to S.E. Postnova water is in living matter in a jelly-like state.

In the process of visualization, the water in the boundary layer looks more like jelly, or rather liquid crystal. Considering the moment that Living being consists on average 80% of water, and water from the "boundary layer" of this amount is about 10% of the total, while the body spends a huge amount of energy to maintain this layer, but apparently, it also uses it as a means production of free energy. Now let's bring anisotropy here, and everything falls into place. Now we can talk about that from physical properties the health of any living organism depends on water. The property of a young organism is high anisotropy and dissymmetry. This situation can be explained by only one statement. The properties of the boundary water change nonlinearly, approaching the properties of bulk water with distance from the surface, and the quality of the boundary water depends on this surface. If the water is anisotropic, then the epitaxy is pronounced and quite stable. If the water and the environment in which it is located is isotropic, then naturally heteroepitaxial structures are organized near the proteins. This occurs particularly in cancer. How is the fact that the water in the body practically all has the features of border water is proved.

On average, a person has 6 liters of blood, of which 3 liters is plasma, the remaining 3 liters are erythrocytes. The surface of erythrocytes is 3500 sq. m. And if three liters of plasma are distributed with a thickness of 300 microns. then, even in a large vessel, water is in a boundary state or otherwise crystalline hydrate state. But its exact name is the allotropic form of water! Now it is possible to propose a new mechanism for the transfer of oxygen and carbon monoxide with the blood stream and their exchange in the lungs. The same applies to the folding of proteins and DNA replication, and the transport of ions through the membrane, and naturally to the formation of free energy in living matter. This mechanism is crystalline hydrate and depends on the degree of anisotropy and the frequency of the autowave process. Both the Hooke and Young modulus and the shifts of epitaxial films in membranes and layers depend on the properties of the boundary water. The sizes of prokaryotic cells are on average 0.5-5 microns (1.7% of the height of the boundary layer), and the sizes of eukaryotic cells are on average from 10 to 50 microns (17% of the height of the boundary layer).

Consequently, the size of cells is limited by surface water and its properties, and these are already signs of a mechanism for the implementation of energy dissipation pathways. Now let's touch on the saint - the saints of our three-dimensional world - geometry and water molecules ... Solid state physics says: "There are no solid crystalline materials that have fivefold symmetry in their structure." Therefore, polyhydrons with 5-fold vertices do not allow the construction of a correctly positioned crystal structure!

That is why boundary water acquires the properties of solid structures being close to their surfaces. Why is this happening? First, the water molecule has fivefold symmetry. They have a 5-fold identical rotating transformation around symmetrical axes through their tops. The tetrahydrone of water rotates, and 20 tetrahydrons share one vertex and form the icosohydrone. These clusters are the most dense, which is why they represent the least amount of free energy among the possible groups! Amino acids and proteins in the allotropic phase, on the contrary, have more than enough free energy ... The number 20 - icohydrone - suggests that 20 amino acids are also the basis of all proteins ... fill the space properly, requiring a different order. In fact, they are constantly forced to undergo frustration (stirring). That is why the tropism of water to amino acids is the most important condition for the emergence of free energy in a revived non-living matter.

Thus, boundary water can be considered as an accumulation of icosahydrons of water molecules with an unstable crystal structure. Therefore, this water can be considered relict living water. For dense packing always has free surfaces and does not fit into an order that kills internal dynamism without direct contact with metabolic transport and water transfer of energy. This can also explain why DNA also has a 5 - fold helix (alpha and beta forms) and inside this molecule there are 5 - fold rings ... As we know in ancient prokaryotes, DNA is circular ... Water in a living organism has an installation of insulating islands (domains) in a nonequilibrium state, and the balance of local and general stability criteria determines the real dynamics of the charge distribution. This is why the charging wave

can be frozen as a standing wave (soliton) and a local stable group can travel through the material. This is a dynamic equilibrium for the frustration effects of living matter. Dynamic frustration of living protein and water molecules is a quantitative manifestation, or more precisely, a conformational interaction for solving general and particular problems in a living system. Naturally, in such systems, the memory of the past remains forever. That is why boundary relict water, even in a scanty amount added to a sick or old organism, will instantly remind the whole organism how to function correctly! Moreover, it depends on the side of rotation of its icosahydrons to be "golden dissymmetry", high anisotropy in tissues and organs or not ...

Chaotropic and kosmotropic properties of intracellular and intercellular water also depend on the properties of boundary water. In which there is both heavy water and tritium, and all the structures of the cell change in the same volume. In addition, we know that the water in the tumor is different ... It is all isotropic, i.e. not borderline. The increase in the incidence of cancer also confirms the approaching catastrophe for all living things ... Water on the planet is distorted by humanity in the truest sense of the word! Now let's imagine that the water entering the body is spoiled by impurities and contaminated with xenobiotics ... Such water is not able to transform into a borderline or allotropic form !!! For example, the same water with gas cannot be drunk and this is an axiom. For it already knowingly has a cluster structure. It makes no sense to say that sweet fizzy drinks like Coca Cola are much more harmful than any carcinogen.

Just as troubles do not come alone, so diseases prefer to visit a person in whole flocks. And there is only one reason - the lack of border water. Old age is also the prerogative of drought ... Therefore, by bringing the water to perfection, it can heal all diseases and old age.

It is also now quite obvious to us that information about substances in water is kept quite well, and it can be transmitted through the TTS - system. Now let's combine this phenomenon with border water ... and we get super-effective healing, rejuvenating and healing in the literal sense of the word ... water. For such water carries information about any drug, plant and "settles" only where it is intended. This is what humanity has been looking for throughout its history. A panacea.

Conclusion.

Water is the most amazing and most mysterious substance on Earth. It plays an essential role in all life processes and phenomena occurring on our planet and beyond.

The outer shell of our planet inhabited by living organisms - the biosphere is a repository of life on Earth. Its fundamental principle, its irreplaceable component is water. Water is and construction material, which is used to create all living things, and the environment in which all life processes take place, and a solvent that removes substances harmful to it from the body, and a unique transport that supplies biological structures with everything necessary for the normal course of complex physical and chemical processes in them. And this all-encompassing effect of water on any living structure can be not only positive, but also negative. Depending on its state, water can be both the creator of blooming life and its destroyer - it all depends on its chemical and isotopic composition, structural, bioenergetic properties. The abnormal properties of water were discovered by scientists as a result of long and laborious research. These properties are so familiar and natural in our everyday life that an ordinary person is not even aware of their existence. At the same time, water, the eternal companion of life on Earth, is truly original and unique.

Water can be liquid, solid and gaseous. It takes the form of the vessel in which it is poured. Water is able to transmit information, "memorize" words and thoughts, and activate the healing mechanism in the human body. Water cleans not only from physical, material dirt, but also from energy dirt.

Our ancestors, who lived many centuries ago, did not know Coca-Cola, lemonade, beer and other pleasant drinks and quenched their thirst natural water... And this water was, in modern terms, good quality. This means that there were no harmful impurities in it, such as various carcinogens, oil products, etc. And in those distant times people, of course, were sick, but the causes of illness were most often determined not by the use of water.

Learning about the amazing and mesmerizing properties of water begins from the contemplation of beautiful structural creations and the touch of the musical harmony of water presented by the Japanese scientist Masuru Emoto. Shocking experiments on climate control, the effect of water on the health of humans and ecosystems, the phenomena of electromagnetism in water and the facts of non-local interactions of aquatic environments, including biological ones - this is a small list of the range of amazing phenomena that form a halo of mystery around water.

In these manifestations, even to a person who is ignorant of the depths of modern science, it becomes clear that water is not a construction of two hydrogen atoms and one oxygen atom, but something much more, possessing unique properties, including the ability to perceive information in oneself, both about the state of the environment and about biological objects interacting with it. At the same time, the response of water to such an impact has a non-local character, since it can manifest itself both in the past and in the future.

Water itself has no nutritional value, but it is an indispensable part of all living things. None of the living organisms on our planet can exist without water.

All living plant and animal creatures consist of water:
fish - by 75%; jellyfish - by 99%; potatoes - by 76%; apples - by 85%; tomatoes - 90%; cucumbers - by 95%; watermelons - by 96%.

In general, the human body consists by weight of 50-86% of water (86% in a newborn and up to 50% in the elderly). The water content in different parts of the body is: bones - 20-30%; liver - up to 69%; muscles - up to 70%; brain - up to 75%; kidneys - up to 82%; blood - up to 85%.

This circumstance allowed the science fiction writer V. Savchenko to declare that a person “has much more reason to consider himself a liquid than, say, a forty percent solution of caustic soda”.

Throughout his life, a person deals with water every day. He uses it for drinking and food, for washing, in summer for rest, in winter for heating.
For humans, water is a more valuable natural resource than coal, oil, gas, iron, because it is irreplaceable.

A person can live without food for about 50 days, if during a hunger strike he drinks fresh water, without water he will not live even a week - death will come in 5 days. According to medical experiments, with a loss of moisture in the amount of 6-8% of the body weight, a person falls into a semi-faint state, with a loss of 10%, hallucinations begin, with 12% a person cannot recover without special medical care, and with a loss of 20%, inevitable death occurs. ...

In the human body, water:

moisturizes oxygen for breathing;
regulates body temperature;
helps the body absorb nutrients;
protects vital organs;
lubricates the joints;
helps convert food into energy;
participates in the metabolism;
removes various waste products from the body.

A person begins to feel thirsty when the amount of water in his body decreases by 1-2% (0.5-1.0 liters). Loss of 10% moisture from body weight can lead to irreversible changes in the body, and the loss of 20% (7 - 8 liters) is already fatal.

An ordinary person loses 2-3 liters of water per day. In hot weather, with high humidity, water consumption increases during sports. Even through breathing, a person loses almost half a liter of water every day.

The correct drinking regime implies the preservation of the physiological water balance - this is the balancing of the intake and formation of water with its release.

The daily need for an adult in water is 30-40 grams per 1 kg of body weight. Approximately 40% of the body's daily need for water is met with food, the rest should be taken in the form of various drinks. In the summer, you need to consume 2 - 2.5 liters of water daily. In hot regions of the planet - 3.5 - 5.0 liters per day, and at an air temperature of 38–40 C and low humidity, those working in the open air will need 6.0 - 6.5 liters of water per day. At the same time, you cannot be guided by whether you are thirsty or not, since this reflex occurs too late and is not an adequate indicator of how much water your body needs.
It is interesting to know that porridge contains up to 80% water, bread - about 50%, meat - 58-67%, vegetables and fruits - up to 90% water, i.e. "Dry" food consists of 50-60% water.

And about 3% (0.3 l) of water is formed as a result of biochemical processes in the body itself.
According to some estimates, over 60 years of life, a person drinks about 50 tons of water - a whole cistern!
By participating in the metabolism, water helps to reduce body fat and reduce weight. Many of those who want to lose weight believe that their body retains water and try to drink less of it. However, water is a natural diuretic and, if you drink it, you will lose weight.

If the body receives a sufficient amount of water, then a person becomes more energetic and resilient. It is easier for him to control his weight, as digestion improves, and when you are drawn to snack, it is often enough to just drink water to reduce your appetite. Symptoms of dehydration include dry skin (may be itchy), fatigue, poor concentration, headaches, increased blood pressure, poor kidney function, dry cough, and back and joint pain.

Research has already shown that drinking enough water can minimize back pain, migraines, rheumatic pains, and lower blood cholesterol and blood pressure, thereby reducing the likelihood of a heart attack. Drinking enough water is one of the best ways to prevent kidney stones. Since water does not contain salts, fat, cholesterol and caffeine, then, accordingly, it is excreted from the body in a different way.

German scientists, after conducting tests on student volunteers, came to the conclusion that those who drink more water and beverages show more endurance and a penchant for creativity than those who drink less.

Regular water intake improves thinking and brain coordination. The brain and the entire body will be sufficiently energized the necessary substances, if the water we drink is of high quality, that is, it is rich in minerals. A healthy person should not limit himself to drinking, but it is much more beneficial to drink often and little by little. It is harmful to drink a lot of liquid at once, since all the liquid is absorbed into the bloodstream, and until its excess is excreted from the body by the kidneys, the heart receives an excessive load.

Thus, we can conclude that the role of water for humans is enormous. Today, everyone can create for themselves the conditions for maintaining priceless water balance by correct organization drinking regime.

Water is the source of life on Earth, a great natural value, covering 71% of the surface of our planet, the most common chemical compound and necessary foundation for the existence of all life on the planet. The high content in plants (up to 90%) and in the human body (about 70%) only confirms the importance of this component, which is tasteless, odorless and colorless.

Water is life!

The role of water in human life is invaluable: it is used for drinking, food, washing, various household and industrial needs. Water is life!

The role of water in human life can be determined by the share it occupies in the body and organs, each cell of which is rich in an aqueous solution of essential nutrients. Water is one of effective means physical education, widely used for personal hygiene, health fitness, hardening, water sports.

Biochemical properties of water

In human life, water is capable of dissolving some acids, bases and salts, which are ionic compounds and some polar non-ionic formations (simple alcohols, amino acids, sugars), called hydrophilic (from Greek literally - a tendency to moisture). Nucleic acids, fats, proteins and some polysaccharides - hydrophobic substances (from Greek - fear of moisture) - are beyond the power of liquids.

The biological value of water is quite large, since this priceless liquid is the main medium for the internal processes taking place in the body. In percentage terms, the presence of water in the body is as follows:

Body systems
Adipose tissue

An interesting statement on this matter by science fiction writer V. Savchenko, who revealed in one phrase the meaning of water: a person has much more motives to consider himself a liquid, in contrast, for example, to a 40% sodium solution. And there is a popular joke among biologists that water "invented" a person as a means of its own transportation, the main component of whose body it is. 2/3 of its total amount is contained inside the cells and is called "intracellular" or "structured" fluid, which is able to ensure the body's resistance to the influence of negative environmental factors. One third of the water is outside the cells, and 20% of this amount is the intercellular fluid itself, 2% and 8%, respectively, the water of the lymph and blood plasma.

The value of water in human life

The value of the natural component in life and everyday life is simply invaluable, since without it, existence is impossible in principle.

Water is essential for life because:

moisturizes inhaled oxygen;
helps the body in the high-quality assimilation of nutrients;
promotes the conversion of food into energy and normal digestion;
participates in the ongoing metabolism and chemical reactions;
removes excess salts, slags and toxins;
debugs body temperature;
provides skin elasticity;
regulates blood pressure;
prevents the formation of kidney stones;
is a kind of "lubricant" for joints and a shock absorber for the spinal cord;
protects vital organs.

The water cycle in the body

One of the conditions for the existence of all living things is a constant water content, the amount of water entering the body depends on a person's lifestyle, his age, physical health, and environmental factors. During the day, up to 6% of the water available in the body is exchanged; half of its total is renewed within 10 days. So, per day, the body loses about 150 ml of water with feces, about 500 ml with exhaled air, and the same amount with sweat and 1.5 liters is excreted in the urine. A person receives about the same amount of water (about 3 liters per day) back. Of these, a third of a liter is formed in the body itself during biochemical processes, and about 2 liters are consumed with food and drinks, and the daily requirement for exclusively drinking water is about 1.5 liters.

V recent times experts have calculated that a person should still drink about 2 liters of pure water a day in order to prevent even the slightest dehydration of the body. The same amount is recommended to be consumed by yogis who know the true meaning of air and water. An absolutely healthy human body, ideally, should have a state of water balance, otherwise called water balance.

By the way, German scientists, after a series of experiments conducted on students, found out that those who drink water and drinks more than others show great self-control and a penchant for creativity. Water plays a stimulating role in human life, filling with energy and vitality.

According to some estimates, over 60 years of life, a person on average drinks about 50 tons of water, which is commensurate with almost a whole cistern. It is interesting to know that ordinary food consists of half water: in meat it is up to 67%, in cereals - 80%, vegetables and fruits contain up to 90%, bread - about 50%.

High water consumption situations

Usually a person receives about 2-3 liters of water per day, but there are situations in which the need for it increases. It:

Increased body temperature (more than 37 ° C). With each increasing degree of water, 10% more of the total amount is required .
Hard physical work in the fresh air, in which you need to drink 5-6 liters of liquid.
Work in hot shops - up to 15 liters.

A deficiency of valuable fluid is the cause of many diseases: allergies, asthma, overweight, high blood pressure, emotional problems (including depression), and its absence leads to a disruption in the performance of all body functions, undermining health and making it vulnerable to disease.

Loss of water up to 2% of the total body weight (1 - 1.5 liters) will make a person feel thirsty; the loss of 6 - 8% will lead to a semi-fainting state; 10% will cause the appearance of hallucinations and impaired swallowing function. The deprivation of 12% of water from the total body weight will lead to death. If without food a person is able to survive for about 50 days, provided that drinking water is consumed, then without it - a maximum of 5 days.

In fact, most people drink less water than the recommended amount: only a third, and the emerging ailments are in no way associated with a lack of fluid.

Signs of a lack of water in the body

The first signs of dehydration:

Stable supply of water to the body in the required amount helps to provide vitality, get rid of ailments and many serious diseases, improve thinking and coordination of the brain. Therefore, the emerging thirst should always be tried to quench. At the same time, it is better to drink often and little by little, since a large amount of liquid for the purpose of a one-time replenishment of the daily norm will be completely absorbed into the blood, which will put a tangible load on the heart until the kidneys remove water from the body.

The body's water balance is a direct path to health

In other words, water in human life with a properly organized drinking regime is able to create acceptable conditions for maintaining the required water balance. It is important that the liquid is of high quality, with the presence of the necessary minerals. The situation in the modern world is paradoxical: water, the source of life on Earth, can be dangerous to life itself, carrying various infections with almost every drop. That is, only pure water, the quality problem of which in modern world very relevant.

Water scarcity is a terrible future for the planet

More than 40 countries now suffer from water shortages due to the aridity of many regions. In 15 - 20 years, even according to the most optimistic forecasts, every person will understand the importance of water on Earth, since the problem of its shortage will affect 60 - 70% of the world's population. In developing countries, the water deficit will grow by 50%, in developed countries - by 18%. As a result, international tension around the issue of water scarcity will increase.

Contaminated water as a result of human activities

This is due to geophysical conditions, human economic activities, often ill-considered and irresponsible, which significantly increases the load on water resources and leads to their pollution. A huge amount of water goes to the needs of cities and industry, which not only consume, but also pollute water, dumping about 2 million tons of waste into water bodies every day. The same goes for agriculture, where millions of tons of waste products and fertilizers flow into water bodies from farms and fields. In Europe, out of 55 rivers, only 5 are considered clean, while in Asia all rivers are extremely littered with agricultural waste and metals. In China, 550 out of 600 cities are experiencing water shortages; because of strong pollution in water bodies, fish do not survive, and some rivers flowing into the ocean simply do not reach it.

What flows from the taps

And why go far, if the quality of water, which leaves much to be desired, concerns almost every person. The importance of water in human life is great, this is especially true when it is consumed, when sanitary standards go against the quality of the consumed liquid, which contains harmful pesticides, nitrites, oil products, salts of heavy metals. Half of the population receives water hazardous to health, which causes about 80% of all known diseases.

Chlorine is dangerous!

Water poisoning is much more terrible than food poisoning, because water in human life, unlike food, takes part in all biochemical processes of the body. Dioxins accumulated in the body decompose very slowly, practically for decades. Causing disruption of the endocrine system, reproductive functions, they destroy the immune system, cause cancer and genetic abnormalities. Chlorine is the most dangerous killer of our time: killing one disease, it gives rise to another, even worse. After the global chlorination of water began in 1944, epidemics of heart disease, dementia and cancer began to manifest en masse. The risk of cancer is 93% higher than that of those who drink unchlorinated water. There is only one conclusion: tap water should never be drunk. The ecological significance of water is the No. 1 problem in the world, since if there is no water, there will be no life on Earth. Therefore, an indispensable condition for maintaining health is its cleaning and compliance with sanitary and epidemiological standards.

Water plays an extremely important role in nature. It creates favorable conditions for the life of plants, animals, microorganisms. Water remains a liquid in the temperature range most favorable for their life processes; for a huge mass of organisms, it is a habitat. The unique properties of water are of unique value for the vital activity of organisms. In reservoirs, water freezes from top to bottom, which is of great importance for the organisms living in them.

The abnormally high specific heat capacity of water favors the accumulation of a colossal amount of heat, promotes slow heating and cooling. Organisms living in water are protected from sharp spontaneous fluctuations in temperature and composition, as they constantly adapt to slow rhythmic fluctuations - daily, seasonal, annual, and so on. Water has a softening effect on weather and climatic conditions. It constantly moves in all spheres of the Earth, along with the circulating currents of the atmosphere - over long distances. The circulation of water in the ocean (sea currents) leads to planetary heat and moisture exchange. The role of water as a powerful geological factor is known. Exogenous geological processes on Earth are associated with the activity of water as an erosive agent. Erosion and destruction of rocks, soil erosion, transport and deposition of substances are important geological processes associated with water.

Most of the organic matter of the biosphere is a product of photosynthesis, as a result of which organic matter is formed from carbon dioxide and water in plants that use the light energy of the sun. Water is the only source of oxygen released into the atmosphere during photosynthesis. Water is essential for biochemical and physiological processes in the body. Living organisms, including humans, which are 80% water, cannot do without it. Loss of 10-20% of water leads to their death.

Water plays a huge role in human life support. It is used by him directly for drinking and household needs, as a means of transportation and raw material for obtaining industrial and agricultural products, has a recreational value, its aesthetic value is great. This is not a complete enumeration of the role of water in nature and human life.

In nature, water is not found in a chemically pure form. It represents solutions complex composition, which include gases (O 2, CO 2, H 2 S, CH 4 and others), organic and mineral substances. Suspended particles are present in moving streams of water. The vast majority of chemical elements are found in natural waters. Ocean waters contain on average 35 g / dm 3 (34.6-35.0 ‰) salts. Most of them are chlorides (88.7%), sulfates (10.8%) and carbonates (0.3%). The least mineralized are the waters of atmospheric precipitation, ultra-fresh waters of mountain streams and fresh lakes.

Depending on the content of dissolved minerals, waters are distinguished: fresh with a content of dissolved salts up to 1 g / dm 3, brackish - up to 1-25 g / dm 3, salty - more than 25 g / dm 3. The boundary between fresh and brackish waters is taken according to the average lower limit of human taste perception. The boundary between brackish and salty waters is established on the basis that, with a mineralization of 25 g / dm 3, the freezing point and maximum density are quantitatively the same.

The most familiar and most incredible substance on Earth is water. The value of water cannot be overestimated in the life of all living things on the planet, it is present in every moment of our existence. Being the predominant element in the composition of any organism, water also controls its life.

Water in nature

Throughout its existence, humanity has been trying to unravel the mystery of this amazing and contradictory element. How did it arise, how did it get to our planet? Probably, no one will be able to answer this question, but everyone knows that the importance of water in nature and human life is unimaginably great. One thing is absolutely true - today there are as many water reserves on Earth as there was at the birth of the universe.

The unique properties of water to shrink when heated and expand when freezing are another reason to be surprised. No other substance has similar properties. And its ability to move from one state to another, so familiar and at the same time amazing, playing an exceptional role, makes it possible for all living organisms to exist on Earth. The Supreme Reason allotted the main party to water in maintaining life and participating in constantly occurring natural processes.

The water cycle

This process is called the hydrological cycle, which is a continuous circulation of water from the hydrosphere and surface of the earth into the atmosphere and then back. There are four processes involved in the cycle:

evaporation;
condensation;
precipitation;
water runoff.

Once on the ground, part of the precipitation, evaporating, condenses, the other part, due to the runoff, fills the reservoirs, the third turns into groundwater, going underground. So, constantly moving, feeding waterways, plants and animals and preserving its own reserves, it wanders, protecting the Earth, water. The meaning of water is obvious and undeniable.

The circulation mechanism and its types

In nature, there is a large cycle (the so-called world), as well as two small - continental and oceanic. The precipitation collected over the oceans is carried by the winds and falls onto the continents, and then returns to the ocean with runoff. The process when oceanic water continuously evaporates, condenses and falls back into the ocean in the form of precipitation, is called the small oceanic gyre. And all similar processes taking place over land are combined into a small continental circulation, in which water is the main character. Its importance in the natural processes of continuous circulation, which maintains the water balance of the Earth and ensures the existence of living organisms, is indisputable.

Water and man

Having no nutritional value in the usual sense, water is the main component of any living organism, including humans. No one can exist without water. Two-thirds of any organism is water. The value of water is extremely important for the proper functioning of all systems and organs.

Throughout life, a person comes into contact with water every day, using it for drinking and food, hygiene procedures, rest and heating. There is no one on earth
more valuable natural material, as vital and irreplaceable as water. Going without food for quite long periods of time, a person will not live without water even 8 days, since when the body is dehydrated within 8% of the body weight, a person begins to faint, 10% cause hallucinations, and 20% inevitably cause death.

Why is water so important for a person? It turns out that water regulates all basic life processes:

normalizes oxygen humidity, increasing its absorption;
carries out thermoregulation of the body;
dissolves nutrients, helping the body to absorb them;
moisturizes and protects vital organs;
forms a protective lubricant for joints;
improves metabolic processes in the activity of body systems;
promotes the evacuation of waste from the body.

How to maintain water balance

On average, a person loses 2-3 liters of water per day. In more extreme conditions e.g. in hot weather, high humidity and physical activity water losses are increasing. To maintain a normal physiological water balance of the body, it is necessary to balance the flow of water with its excretion through a competent drinking regime.

Let's make some calculations. Considering that the daily human need for water is 30-40 grams per 1 kg of body weight and about 40% of the total need comes from food, the rest should be taken in the form of drinks. In summer, the daily water consumption is 2-2.5 liters. Hot regions of the planet dictate their requirements - 3.5-5.0 liters, and in extremely hot conditions up to 6.0-6.5 liters of water. Do not allow dehydration of the body. Alarming symptoms of this trouble are dry skin, accompanied by itching, fatigue, a sharp decrease in concentration, blood pressure, headaches and general malaise.

Useful effect

Interestingly, by taking a direct part in metabolic processes, water contributes to weight loss. There is a common misconception that people who want to lose weight need to drink less water, since the body retains water, causing significant harm. You cannot drive your own body into even greater stress, knocking it out of the usual water exchange. In addition, moisture, being a natural diuretic, tones up kidney function, causing weight loss.

Receiving the optimal amount of water, a person adds strength, energy and endurance. It is easier for him to control weight, since even the psychological inconveniences from forced changes with a decrease in the usual diet are easier to bear. Scientific research it has been proven that daily consumption of a sufficient amount of pure water helps to fight severe ailments - it helps to relieve back pain, migraine symptoms, reduce blood sugar and cholesterol levels and blood pressure. In addition, by toning up the kidneys, water inhibits the formation of stones. It has been proven that creative people tend to drink a lot, and she pushed great artists to create masterpieces. sea water... The meaning of water, it turns out, is also important in art.

Water exchange of plants

Just like a person, any plant needs water. Have different plants it makes up from 70 to 95% of the mass, controlling all the processes that take place. The metabolism in a plant is possible only with a large amount of moisture; therefore, the value of water for plants is undeniably great. Dissolving minerals in the soil, water delivers them to the plant, ensuring their continuous flow. Without water, seeds will not germinate, the process of photosynthesis will not take place in green leaves. The water that fills the cells of the plant ensures its vitality and preservation of a certain shape.

The most important condition for the life support of a plant organism is the ability to absorb water from the outside. The plant, receiving water, mainly from the soil with the help of the roots, delivers it to the ground parts of the plant, where the leaves evaporate it. Such a water exchange exists in every organic system - water, getting into it, gives off nutrients, evaporates or is released, and then again, enriched with useful substances, enters the body.

Another amazing way of water penetration into living cells is its osmotic absorption, that is, the ability of water to accumulate from the outside into cell solutions, increasing the volume of fluid in the cell.

The art of consuming water

The constant use of pure water significantly improves the mental activity of the brain and coordination of movement, and therefore, the value of water for the vital activity of brain cells is especially valuable. Therefore, a healthy person should not limit himself to drinking, but some rules should be followed:

drink a little, but often;
Do not drink a lot of water at once, as an excess of fluid in the blood will put unnecessary stress on the heart and kidneys.

So, the importance of water for living organisms is enormous. Therefore, the creation of conditions for maintaining their own water balance is necessary for every person.

Water in human life. Biological and ecological significance of water

Water is the source of life on Earth, a great natural value, covering 71% of the surface of our planet, the most common chemical compound and a necessary basis for the existence of all life on the planet. The high content in plants (up to 90%) and in the human body (about 70%) only confirms the importance of this component, which is tasteless, odorless and colorless.

The role of water in human life is invaluable: it is used for drinking, food, washing, various household and industrial needs. Water is life!
The role of water in human life can be determined by the share it occupies in the body and organs, each cell of which is rich in an aqueous solution of essential nutrients. Water is one of the effective means of physical education, widely used for personal hygiene, health-improving physical education, hardening, and water sports.

Biochemical properties of water

The preservation of the elasticity and volume of a living cell would be impossible without water, as well as a significant part of the body's chemical reactions that occur precisely in aqueous solutions. Such a valuable liquid is indispensable for its thermal conductivity and heat capacity, which provides thermoregulation and protects against temperature extremes.
In human life, water is capable of dissolving some acids, bases and salts, which are ionic compounds and some polar non-ionic formations (simple alcohols, amino acids, sugars), called hydrophilic (from Greek literally - a tendency to moisture). Nucleic acids, fats, proteins and some polysaccharides - hydrophobic substances (from Greek - fear of moisture) - are beyond the power of liquids.

Recently, experts have calculated that a person should still drink about 2 liters of pure water a day in order to prevent even the slightest dehydration of the body. The same amount is recommended to be consumed by yogis who know the true meaning of air and water.

A deficiency of valuable fluid is the cause of many diseases: allergies, asthma, overweight, high blood pressure, emotional problems (including depression), and its absence leads to impaired performance of all body functions, undermining health and making it vulnerable to disease.

In fact, most people drink less water than the recommended amount: only a third, and the emerging ailments are in no way associated with a lack of fluid.

Water scarcity is a terrible future for the planet

Rather, the very problem of the availability of drinking water is becoming vitally important, turning into an increasingly scarce product every day. Moreover, the importance of water on Earth and its lack in international relations are discussed at the highest level and often in a conflictual way.
More than 40 countries now suffer from water shortages due to the aridity of many regions. In 15 - 20 years, even according to the most optimistic forecasts, every person will understand the importance of water on Earth, since the problem of its shortage will affect 60 - 70% of the world's population.

Chlorine is dangerous!

To avoid possible infection with any infection, the water is chlorinated, which does not diminish the danger in any way. On the contrary, chlorine, which destroys many dangerous microbes, forms chemical compounds harmful to health and provokes diseases such as gastritis, pneumonia, and oncology. When boiled, it does not have time to dissolve completely and combines with organic substances always present in water. In this case, dioxins are formed - very dangerous poisons, surpassing in their strength even potassium cyanide. Water poisoning is much more terrible than food poisoning, because water in human life, unlike food, takes part in all biochemical processes of the body. Dioxins accumulated in the body decompose very slowly, practically for decades.

the importance of water in human life and in nature is very great. because we need water the most. without food a person can live for several days, and without water only 3 days or more. plants will dry out without water. animals can also die of thirst. therefore, water is the most essential in human life

Water is the main determinant of the climate on the Earth's surface.

Alexandr borodach

Water is the source of life on the planet
WATER is a colorless, odorless, tasteless, zero-calorie liquid that is essential for all life on Earth. Neither people, nor animals, nor plants can live without water. Neither an elephant nor a microbe can do without it, and there is nothing to replace water with. To maintain health, each of the more than five billion people on earth needs to consume - along with various drinks and food - about two and a half liters of water per day. If there is no water, there will be no life.
Without water, you cannot grow crops or livestock. And if there is no food, there will be no life.
But, fortunately, water is abundant on Earth. Judging by the photographs taken from space, our beautiful blue planet should not be called Earth, but Water. If all the water is evenly distributed over the surface of the Earth, then you get a world ocean 2.5 kilometers deep. And on the square The Pacific the entire dry land of our planet will fit perfectly, and there will still be room.
Of course, most of the water on Earth is found in the seas and oceans, and seawater is salty. If you drink only sea water, you will soon die of thirst and dehydration - the body cannot cope with the excess of salt. You cannot use sea water both in agriculture and in industry: almost the entire crop will die from it and any mechanism will quickly rust. Therefore, in general, sea water is good only if it is desalinated, and this is very expensive.
Fresh water accounts for only 3 percent of the world's water supply. Almost all of it - 99 percent - is enclosed in ice, on mountain tops, or deep underground. Only 1 percent of fresh water is directly available.
It seems that one percent is very little, a drop. Will it not happen that we will be left without fresh water? Unlikely. One magazine says: even distribution would be twice or three times more than enough for today's population of the Earth ”(“ People & the Planet ”).
Basically, the total amount of water on Earth does not decrease or increase. One scientific journal says: “The water we use today may have once quenched a dinosaur's thirst. The fact is that all the water that is on Earth today has existed on the planet - and will always exist ”(Science World).
After all, water circulates endlessly: from the oceans it enters the atmosphere, from there - to the earth, then to the rivers, and then returns to the oceans. A very long time ago, a wise man wrote: “All rivers flow into the sea, but the sea does not overflow; to the place where the rivers flow, they return to flow again ”(Ecclesiastes 1: 7).
Water is the main determinant of the climate on the Earth's surface.
The main role of water is that it is a medium and a source of hydrogen for life. Almost all organic matter in the biosphere is a product of photosynthesis, in which plants use light energy to combine carbon dioxide with water. As you know, photosynthesis cannot take place without water. The process to which the entire life of our planet is obliged. Water is the only source of oxygen released into the atmosphere during photosynthesis. Water is essential for the biochemical and biophysical processes that enable life on Earth. Figuratively speaking, a drop of water contains life.

the importance of water in human life and in nature is very great. because we need water the most. without food a person can live for several days, and without water only 3 days or more. plants will dry out without water. animals can also die of thirst. therefore, water is the most essential in human life
