Everything in nature is harmonious and logical. Everything created on Earth is interconnected and works in tandem. We are so accustomed to some things in nature that we no longer notice their true gift, we treat them as self-evident components of our lives.
Water is one of these substances. We drink, cook, wash, and also quietly pollute the sources of such an integral natural gift as water, without thinking about the consequences of its absence on planet Earth.
And yet, “Water was given the magical power to become the Juice of Life on Earth” ( Leonardo Da Vinci ).
Water is the basis of proper nutrition and healthy image life. On the way, you need to learn how to properly and profitably use the Juice of Life - Water)…

Water is the basis of life on Earth

And here, meaning of water not exaggerated! For a minute, 90% of the human body, its cells and tissues, like all life on the planet, consists of water. The existence of the human, plant and animal world on the planet without clean water is impossible. Being the only and unique substance on the planet that can come in three different states - liquid, gaseous and solid, and also having such a simple chemical formula - H2O - water, nevertheless, conceals a huge amount of mysterious and enigmatic information.

This is what the famous French pilot and writer wrote about water Antoine de Saint-Exupery :

“Water, you have no taste, no color, no smell, you cannot be described, they enjoy you without knowing what you are. It cannot be said that you are necessary for life: you are life itself. You fill us with joy that cannot be explained by our feelings. With you, the forces to which we have already said goodbye return to us. By your grace, the dry springs of our heart begin to bubble within us again. You are the most great wealth in the world…"

The importance of water in human life

What is the importance of water ? HUGE. No exaggeration.
Man is made of water. A person is practically a liquid. And this is a fact).
Depending on age, lifestyle and health, the percentage of water in our body contains from 70 to 90! % of the total volume in cells and tissues, namely:
- 90% of the brain is water;
- 83% of blood is water;
— 22% bone tissue- This is water;
- 75% of our muscle tissue is water!

There are many sayings and jokes on this topic among scientists and writers:
— Science fiction writer V. Savchenko stated that a person “has much more reason to consider himself a liquid than, say, a 40% solution of sodium hydroxide.”
“Water “invented” man as a means of transportation,” biologists sometimes joke.
“Or Du Bois’s wonderful romantic metaphor: “A living organism is animate water.”

What does water do in our body?

1. Water participates in the breathing process, namely, it humidifies the inhaled air;

2. Water regulates body temperature in the body;
3. Water participates in metabolic processes in the body and helps absorb nutrients;
4. Water improves kidney and liver function. The proper functioning of these organs helps eliminate toxins. If there is not enough water, the kidneys turn on an economical mode and retain all toxins in the body. If there is a violation water balance liver functioning decreases, and unresolved poisons and toxins accumulate in the body;
5. Water transports nutrients and oxygen to cells;
6. Water dilates blood vessels, therefore, by fully saturating your body with water, a person suffers less headaches and experiences less fatigue;
7. Water protects internal organs and lubricates joints, preventing the development of arthritis, arthrosis and spinal diseases;
8. Water speeds up and normalizes metabolism, thereby fighting excess weight. Obese people should drink 200 ml more water for every extra 10 kg of weight;
9. Water is the elixir of youth and beauty. Water supplies our skin with moisture and makes it firm and elastic.
10. And finally, the obvious conclusion - Water strengthens the immune system!

Water extends our life day after day, thanks to water we live .

When and how to drink water correctly

Every person needs to drink:
- in the cold season up to 2.5 liters of water;
- in hot weather up to 4 liters of water.
Why? Daily human body loses 3 - 4 liters of water. This is fine. But the balance needs to be maintained and the lost amount of water replenished.
Excretion of substances per day from the human body (according to Starling):
The kidneys excrete 1500 ml/day;
Skin 700-900 ml/day;
Lungs 500 ml/day;
Gastrointestinal tract (intestines) 100 ml/day.

Therefore, it is vitally important to maintain a drinking regime!

A person should consume as much water daily as he loses. The rate of water consumption per day to replenish lost water is up to 40 ml per 1 kg of weight, which is 2 - 2.5 liters.

It is advisable to drink filtered water, not boiled, in small sips. And it’s best to drink “live” or melt water. Place a bottle of water in the freezer. After a while, take it out and leave it warm. Pour some of the thawed water into another container, voila, drink and be healthy.
In the morning on an empty stomach you need to drink 2 glasses of water. I drink water with lemon . This simple drink is very healthy. Lemon water will launch metabolism and cleansing processes of the body. During the day, 20 minutes before meals, drink a glass of water, and an hour after meals, if desired. An insufficient amount of water during the day clogs the body, and the blood becomes acidic.
Remember! Tea, coffee, juices and other liquids are not water - they are food for the body.

How long can a person go without drinking?
Research by the American physiologist E. F. Adolph showed that this measure of time directly depends on the ambient temperature and the regime motor activity. For example, at rest in the shade, at temperatures up to 23°C, a person can last up to 10 days without water. And at an air temperature above 30°C, in the same state of rest, a person can last no more than 2 days.

Water has memory and structure

With the most simple properties We are all familiar with water. More recently, scientists have paid deeper attention to the subject of research on this unique mineral. The impetus for the scientific world was amazing discoveries Japanese water explorer, famous healer Masaru Emoto . Masaru Emoto proved that water has the ability to absorb, store and transmit human thoughts and emotions .
The essence of the experience:

The shape of ice crystals depends on its purity and varies depending on created atmosphere around. Everything matters for their formation - the music played over the water, the words spoken to it, the images shown, and even what people think about the water, whether they pay attention to it or not.

.
So, Emoto showed the water various images, talked, played different music for the water, and then the water was quickly frozen in liquid nitrogen. Next, Masaru Emoto placed frozen layers of water under a powerful microscope and took photographs that showed water drawings with amazing pictures and shapes. Thus, the official scientific discovery was made that water has memory and structure.
Scientist Emoto himself explained it this way: :

“Water’s ability to respond to a very wide range of electromagnetic oscillations (“vibrations” or hados) leads to the fact that it reflects the fundamental properties of the universe as a whole. Every person and the entire Planet consists of water for the most part. Water is the link between spirit and matter. Therefore, I am convinced that we can heal ourselves and planet Earth by consciously cultivating the essential positive emotions and "vibrations" of love and gratitude"

After these experiments, serious research into water began, which has already led to certain results. 4 years ago, scientists announced that using water it was possible to make a computer with a power millions of times greater than existing ones! Very interesting, isn't it?)
Our ancestors, healers and healers, charmed water to solve various problems. They were aware of the magical properties of water, which they now received scientific basis and confirmation. In our time, Kashpirovsky and Chumak actively used this knowledge).

These are such funny poems that fully reflect the message of the article in their humorous manner)):

WATER CARRIER
Amazing question:
Why am I a water carrier?
Because without water -
Neither here nor there!

We rest - we drink water,
We sit down and pour water,
And it turns out - without water,
Neither here nor there!

Both animals and cattle drink,
And trees and flowers, -
Even flies without water -
Neither here nor there!

Grief - must be drowned,
Joy - needs to be soaked,
In every case - without water
Neither here nor there!

Neither shave nor drink,
Neither wash nor swim,
To a man without water -
Neither here nor there!

No, comrades, not in vain
There are rivers and seas,
Because without water
Neither here nor there!

As you know, our body is predominantly composed of water. very large, since water is the most important and integral component for us. It is involved in all metabolic processes and has a significant impact on our condition and health. That is why you need to take care of sufficient quantity and quality of water consumed.

Which daily norm water consumption?

It is generally accepted that the daily water requirement for a person is 1.5 – 2 liters. If you suddenly find that you drink less than this norm, then do not worry, since this norm includes not only pure water, but also the liquid that the body receives from food. Sources of water can be: various dishes prepared with water (borscht, soup), coffee, tea, juices, milk, fruits, vegetables, etc. Water should be drunk regularly, at short intervals throughout the day. (6 – 8 glasses per day).

Water perfectly dissolves various substances that are necessary for the full and normal functioning of all organs and tissues. Water in the human body is constantly in a dynamic state. With its participation, almost all biochemical processes and reactions occur on which metabolism depends. Also the water is good transport system, through which all nutrients (vitamins, macro and microelements) spread throughout the body.

Water cleanses the body of waste and toxins, controls body temperature, and also removes salts from the body. It has a positive effect on human skin (more than 10% of water is in the skin). By drinking enough water, your skin will be healthy, elastic and toned. This liquid also promotes weight loss, since after drinking water, metabolism in the body accelerates by 20 - 30%.

The role of water in the human body and its functions:

• removes various toxins and waste from the body
• saturates oxygen with moisture during breathing
• all metabolic processes occur due to water
• controls body temperature
• lubricates joints
• Helps absorb various nutrients
• is a good natural solvent for many vitamins, macro and microelements
• protection and buffering of vital organs

Some interesting facts about water:

• how more people drinks water, the faster it is eliminated from the body
• a person can live without water from 3 to 8 days
• loss of more than 10% water can lead to death
• overeating can also cause dehydration
• on average a person consumes 60 – 70 tons of water per year
• Drinking water with high Ph extends life by 10 – 20 years
• water helps

Water before workout:

2 - 3 hours before the start of training, you must drink 400 - 700 ml of water. Why do you need to drink so much water before training when you can take a bottle of water with you and drink it as you go? The fact is that it takes some time to absorb water. While working in the gym, the body temperature rises and strong and rapid sweating occurs, water begins to quickly leave the body.

By the time you become thirsty, your body will have lost 2–3% of fluid, which is quite a lot. And before the water you drink is absorbed, the body will lose even more fluid, and this is, as it were, harmful to health. Therefore, it is necessary to provide the body with the necessary amount of water in advance.

Water during training:

Very significant the role of water in the human body plays during training, as it is needed to maintain the required water balance. As already mentioned, water leaves the body very quickly during training. During dehydration, the amount of blood in the body decreases, which affects its ability to transport oxygen, and all this subsequently affects training performance and human health.

To ensure good training productivity and correct work muscles, you need to constantly maintain fluid levels in the body. To do this, you can take 1–2 liters of water with you and drink it in small sips throughout your workout.

Water after workout:

After training, over the next 2 - 3 hours you need to drink 500 - 700 ml of water in order to replenish lost reserves.

Consequences of lack of water in the body:

The most serious consequence of not having enough water can be dehydration. What is dehydration? Dehydration is a pathological condition of a person that occurs when the level of water in the body decreases below the physiological norm. This can happen when there is insufficient intake of it into the body, or as a result of its rapid loss.

Symptoms of dehydration:

• a person is very thirsty
• Not a large number of urine
• urine color changes (gets very dark)
• the person experiences severe weakness
• severe fatigue
• low blood pressure
• weak pulse
• loss of consciousness

A person will feel thirsty when 1 - 2% of water (500 - 1000 ml) leaves his body. A loss of 10% of moisture from your own body weight leads to irreversible processes in the body, and a loss of 20% (7000 - 8000 ml) is fatal. remember, that daily water consumption rate is 1.5 – 2 liters.

What should the water be like?

The main quality criterion of water is its Ph. Ph is a measure that shows the level of activity of hydrogen ions in water, thereby quantifying its acidity. Human blood has a Ph of 7.34 – 7.44. This acid-base balance in the human body is the most favorable. Violations of Ph levels in the blood can lead to various diseases. For example, an acidic environment can provoke diseases such as arthritis, osteoporosis and various cardiovascular diseases.

How to find out the Ph of water?

The pH of water can be determined in several accessible and simple ways. The first and most in a simple way there will be a purchase mineral water in bottles that indicate full composition and Ph of water. The second way is to use special indicators (litmus, phenolphthalein, sodium benzenesulfonate). These are organic substances that, when added to water, change color depending on the acidity of the water. The third method is using a Ph-meter, this is a special device that allows you to very accurately determine the acid-base balance of water.

Now you understand how important the role of water in the human body. Water is life! Drink quality water and be healthy!

Sincerely,

Water is the most important component of our habitat. After air, water is the second most important component necessary for human life.

How important water is is evidenced by the fact that its content in various organs is 70 - 90%. With age, the amount of water in

the body changes. A three-month fetus contains 90% water, a newborn 80%, an adult - 70%. Water is present in all tissues of our body, although it is distributed unevenly:

The brain contains - 75%

Heart - 75%

Lungs - 85%

Liver - 86%

Kidneys - 83%

Muscles - 75%

Blood - 83%.

Today, more than ever, it is very important for our body to receive clean water with a balanced mineral composition. It carries our body's waste, delivers lubricant to our joints, stabilizes our temperature, and is the lifeblood of the cell.

Water is necessary to maintain everything metabolic processes, she takes part in the assimilation nutrients cells. Digestion becomes possible only when food becomes water-soluble. Crushed tiny particles of food acquire the ability to penetrate through the intestinal tissue into the blood and intracellular fluid. More than 85% of all metabolic processes in our body occur in aquatic environment, therefore, a lack of clean water inevitably leads to the formation free radicals in human blood, which leads to premature aging of the skin and, as a consequence, the formation of wrinkles.

Consumption of clean water ensures normal functioning internal organs. It keeps your body flexible, lubricates your joints and helps nutrients penetrate. Good body supply clean water helps fight excess weight. This is expressed not only in reducing excessive appetite, but also in the fact that a sufficient amount of clean water helps to process already accumulated fat. These fat cells, with the help of a good water balance, become able to leave your body.

Water is a coolant and thermostat. It absorbs excess heat and removes it, evaporating through the skin and respiratory tract. Water moisturizes the mucous membranes and the eyeball. In the heat and during physical exercise, intense evaporation of water from the surface of the body occurs. Consuming cool, clean water, which is absorbed into the blood from the stomach, ensures timely cooling of your body, protecting it from overheating. During training, for the normal functioning of the body, you need to drink in small portions, about 1 liter per hour. Even if you don't bother too much physical exercise, it is still necessary to constantly replenish the water deficit. The atmosphere in modern buildings is often overheated and air-conditioned. This dries the air and dehydrates the body. The same thing happens when traveling by train, plane and car. Coffee, tea, alcohol - all these joys of life help remove water from the body. An adult can live without food for more than a month, and without water for several days. Dehydration of the body by 10% leads to physical and mental disability. Losing 20% ​​of water leads to death. During the day, from 3 to 6% of the water contained in the body is exchanged. Half of the water contained in the body is exchanged within 10 days.

The amount of water required to maintain hydration depends on age, physical activity, ambient temperature and humidity.

The daily requirement of an adult is about 2.5 liters.

Clean drinking water also increases the body's defense against stress. It thins the blood, fights fatigue, helps the cardiovascular system, and fights stress. A healthy lifestyle is based on proper nutrition, activity and clean water consumption.

With such a great importance of water for humans, the water must be of appropriate quality, but if the water contains any harmful substances, they will inevitably be distributed throughout the body.

Impact of water resources on human health

The water we consume must be clean. Diseases transmitted through contaminated water cause deterioration in health, disability and death of a huge number of people, especially children, mainly in less developed countries, for which a low level of personal and communal hygiene is common. Diseases such as typhoid fever, dysentery, cholera, and hookworm are transmitted primarily to humans as a result of contamination of water sources with excrement excreted from the body of patients.

Success in the fight against these diseases or the achievement of their complete elimination depends on how the system for removing all metabolic products released from the human body is organized and how the matter of providing clean water to the entire population is organized.

The quality of water is also determined by the presence of chemical inclusions in it, which are first detected by our senses: smell, vision.

Thus, copper microparticles give the water some turbidity, iron - redness.

There are basic quality indicators drinking water. They can be divided into groups:

1. Organoleptic indicators (smell, taste, color, turbidity)

2. Toxicological indicators (aluminum, lead, arsenic, phenols, pesticides)

3. Indicators affecting the organoleptic properties of water (pH, total hardness, petroleum products, iron, manganese, nitrates, calcium, magnesium, permanganate oxidation, sulfides)

4. Chemicals formed during water treatment (residual free chlorine, chloroform, silver)

5. Microbiological indicators (thermotolerant coliforms or E. coli, TMC).

The experience of the laboratory in analyzing water quality has shown that the most common water pollutants (the content of components exceeds the standards) include iron, manganese, sulfides, fluorides, calcium and magnesium salts, organic compounds, etc. What negative properties can these or those give to water? other components if their content is higher than the standards?

The presence of iron in water does not threaten our health. However, an increased iron content in water (more than 0.3 mg/l) in the form of bicarbonates, sulfates, chlorides, organic complex compounds or in the form of highly dispersed suspension gives the water an unpleasant red-brown color, worsens its taste, causes the development of iron bacteria, and sedimentation in pipes and their clogging. If you wash clothes in such water, rust stains will remain on them. Similar stains appear on dishes, sinks and bathtubs.

When drinking water with an iron content higher than the standard, a person runs the risk of acquiring various liver diseases, allergic reactions, etc.

An increased content of manganese in water has a mutagenic effect on humans. At levels in the water supply exceeding 0.1 mg/l, manganese causes stains on plumbing fixtures and linens, as well as off-flavors in drinks. The presence of manganese in drinking water can cause sediment to accumulate in the distribution system. Even at a concentration of 0.02 mg/l, manganese often forms a film on pipes that flakes off as a black residue.

Sometimes drinking water contains a lot of salts of hydrochloric and sulfuric acids (chlorides and sulfates). They give the water a salty and bitter-salty taste.

Drinking such water leads to disruption of activity gastrointestinal tract. Water, in 1 liter of which there are more than 350 mg of chlorides and more than 500 mg of sulfates, is considered unfavorable for health.

The content of calcium and magnesium cations in water gives the water its so-called hardness. Water hardness is expressed in mEq/l (=mol/m3), German degrees (1 mol/m3 = 2.804 German degrees), French degrees (1 mol/m3 = 5.005 French degrees), American degrees degrees (1 mol/m cube = 50.050 American degrees). The optimal physiological level of hardness is 3.0-3.5 mEq/L.

Water highly saturated with salts causes a lot of inconvenience: vegetables and meat are more difficult to boil in it, soap consumption increases during washing, and scale spoils kettles and boilers. Hardness above 4.5 mEq/l leads to intensive accumulation of sediment in the water supply system and on plumbing fixtures and interferes with work household appliances. According to the operating instructions household appliances water hardness should not exceed 1.5-2.0 mEq/l. Constant ingestion of water with increased hardness leads to the accumulation of salts in the body and, ultimately, to joint diseases (arthritis, polyarthritis), and the formation of stones in the kidneys, gall bladder and bladder.

Water is also responsible for human teeth. The incidence of caries depends on how much fluoride is contained in the water. Water fluoridation is believed to be effective in preventing tooth decay, especially in children. The fluoride content in drinking water above sanitary standards (no more than 1.5 mg/l) has a harmful effect on human health. Fluorine is a biologically active microelement, the content of which in drinking water in order to avoid dental caries or fluorosis should be in the range of 0.7-1.5 mg/l.

But in addition to beneficial impurities, water also contains others that are dangerous to the human body.

The presence of sulfides (hydrogen sulfide) in water gives water bad smell, intensifies the corrosion process of pipelines and causes them to become overgrown due to the development of sulfur bacteria. Sulfides have a toxic effect on humans and cause skin irritation. Hydrogen sulfide is toxic to living organisms.

According to domestic researchers, drinking mine water containing 0.2-1 mg/l of arsenic causes a disorder of the central, and especially peripheral, nervous system with the subsequent development of polyneuritis. An arsenic concentration of 0.05 mg/l is considered harmless.

Hygienists first started talking about the health hazards of lead in water in connection with mass intoxications that arose when lead pipes were used in water supply systems. However, elevated concentrations of lead may occur in groundwater. Water is considered harmless if its lead content is no more than 0.03 mg/l.

Strontium is widely distributed in natural waters, and its concentrations vary widely (from 0.1 to 45 mg/l). Its long-term intake in large quantities into the body leads to functional changes in the liver. At the same time, prolonged consumption of drinking water containing strontium at a level of 7 mg/l does not cause functional and morphological changes in tissues, organs and the entire human body. This value is accepted as the standard for strontium content for drinking water.

According to modern scientific data, nitrates in the human intestine are reduced to nitrites under the influence of bacteria living there. Absorption of nitrates leads to the formation of methemoglobin and to a partial loss of hemoglobin activity in oxygen transport

Thus, methemoglobinemia is based on one or another degree of oxygen starvation, the symptoms of which appear primarily in children, especially infants. They get sick mainly during artificial feeding, when dry milk formulas are diluted with water containing nitrates, or when drinking this water. Older children are less susceptible to this disease, and if they get sick, it is less severe, since their compensatory mechanisms are more developed. Drinking water containing 2-11 mg/l of nitrates does not cause an increase in the level of methemoglobin in the blood, while using water with a concentration of 50-100 mg/l sharply increases this level. Methemoglobinemia is manifested by cyanosis, an increase in the level of methemoglobin in the blood, a decrease blood pressure. Experts have recorded these symptoms not only in children, but also in adults. A nitrate content in drinking water of 10 mg/l is harmless.

Uranium is a widely distributed radioactive element in natural waters.

Particularly high concentrations can be found in groundwater. The basis for the rationing of uranium is not its radioactive properties, but its toxic effect as chemical element. The permissible uranium content in drinking water is 1.7 mg/l.

Cadmium accumulates in the kidneys, causes hypertension, weakens the body’s immunity, has negative impact on a person’s mental abilities, because displaces zinc, which is necessary for normal brain function.

Aluminum, accumulating in the body, can cause senile dementia, increased excitability, cause disturbances in motor reactions in children, anemia, headaches, kidney disease, liver disease, colitis, and neurological changes associated with Parkinson's disease.

The maximum permissible concentration in water of some additives used for water clarification (for example, polyacrylamide, aluminum sulfate) is also strictly regulated.

There is such an indicator as permanganate oxidation (standard 5 mg O2/l, no more, this is the total oxygen concentration corresponding to the amount of permanganate ion (MnO4-) consumed when treating a water sample with this oxidizer), which characterizes the measure of the presence of organics in water (gasoline, kerosene, phenols, pesticides, herbicides, xylenes, benzene, toluene) and oxidizable inorganic substances (iron (2+) salts, nitrites, hydrogen sulfide). Organic substances that cause an increased value of permanganate oxidation negatively affect the liver, kidneys, reproductive function, as well as the central nervous and immune system person. Water with permanganate oxidation above 2 mg O2/l is not recommended for consumption.

The toxicity of the above-mentioned components is not so great as to cause acute poisoning, but with prolonged consumption of water containing the mentioned substances in concentrations above standard levels, chronic intoxication can develop, ultimately leading to one or another pathology. It should also be taken into account that the toxic effects of substances can manifest themselves not only when they are taken orally (through the mouth) with water, but also when absorbed through the skin during hygienic (shower, bath) or recreational (swimming pools) procedures. Thus, to answer the question about the suitability of water for drinking, it is necessary to evaluate the sample at least according to the above parameters.

According to sanitary standards, any water that flows from the tap must meet drinking water standards. However, how far are these standards from quality? hot water. When hot water is supplied from the station, the temperature is 130 degrees. Naturally, not a single microbe can withstand such heat. However, on its way, through rusty and worn-out heating networks, the liquid is not only saturated with living and very harmful microorganisms, but also with chemically hazardous substances. First of all, these are iron, lead, arsenic, chromium, and mercury. The main threat, primarily to the health of hair and skin, is active chlorine, which at high temperatures forms an extremely toxic substance in water - dioxin. Microbes and microelements accumulated in hot water are detrimental to damaged areas of leather and hairline. Skin and hair diseases largely become a serious problem due to the entry of pathogenic substances into the affected areas.



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 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.

Water is life!

The role of water in human life is invaluable: it is used for drinking, food, washing, and 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 physical education, widely used for personal hygiene, recreational physical education, hardening, and water sports.

Biochemical properties of water

Preserving 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 take place in aqueous solutions. What makes such a valuable liquid irreplaceable is its thermal conductivity and heat capacity, which provides thermoregulation and protects against temperature changes.

Water in human life is capable of dissolving some acids, bases and salts, which are ionic compounds and some polar nonionic formations (simple alcohols, amino acids, sugars), called hydrophilic (from Greek literally - a tendency to moisture). Liquids cannot handle nucleic acids, fats, proteins and some polysaccharides - hydrophobic substances (from Greek - fear of moisture).

The biological significance of water is quite great, since this invaluable liquid is the main medium for internal processes occurring in the body. In percentage terms, the presence of water in the body is as follows:

Body systems
Adipose tissue

An interesting statement about this by the science fiction writer V. Savchenko, who in one phrase revealed the meaning of water: a person has much more motives to consider himself a liquid, in contrast to, for example, a 40% sodium solution. And there is a popular joke among biologists that water “invented” man as a means of transportation, the main component of whose body it is. 2/3 of it total number is contained inside cells and is called “intracellular” or “structured” fluid, which is capable of ensuring the body’s resistance to the influence of negative factors external environment. The third part of the water is outside the cells, and 20% of this amount is the intercellular fluid itself, 2% and 8% - respectively, the water of lymph and blood plasma.

The importance of water in human life

The importance of the natural component in life and everyday life is simply invaluable, since without it it is impossible to exist in principle.

Water is necessary for life because:

• humidifies inhaled oxygen;
• helps the body in high-quality absorption of nutrients;
• promotes the conversion of food into energy and normal digestion;
• participates in ongoing metabolism and chemical reactions;
• removes excess salts, waste and toxins;
• regulates 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.

Water cycle in the body

One of the conditions for the existence of all living things is a constant content of water, the amount of which enters the body depends on a person’s lifestyle, his age, physical health, environmental factors. During the day, up to 6% of the water available in the body is exchanged; Within 10 days, half of its total quantity is renewed. 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 are excreted in the urine. A person receives approximately the same amount of water (about 3 liters per day) back. Of this, 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 daily requirement in exclusively drinking water it is about 1.5 liters.

IN Lately Experts have calculated that a person should still drink about 2 liters of pure water per 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 should ideally have a state of water balance, otherwise called water balance.

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

According to some estimates, over the course of 60 years of life, an average person drinks about 50 tons of water, which is comparable to almost an entire tank. It is interesting to know that half of ordinary food consists of water: in meat it is up to 67%, in cereals - 80%, vegetables and fruits contain up to 90%, bread - about 50%.

Situations of increased water consumption

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

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

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

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

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

Signs of lack of water in the body

The first signs of dehydration:

A stable supply of water to the body in the required quantity helps ensure vitality, get rid of ailments and many other things. serious illnesses, improving thinking and coordination of the brain. Therefore, you should always try to quench your emerging thirst. It is better to drink often and little by little, since a large amount of liquid for the purpose of one-time replenishment of the daily norm will be completely absorbed into the blood, which will put a noticeable load on the heart until the water is removed from the body by the kidneys.

Water balance in the body is a direct path to health

In other words, water in a person’s life, with a properly organized drinking regime, can create acceptable conditions for maintaining the necessary water balance. It is important that the liquid is of high quality, with 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 is modern world very relevant.

Water shortage is a terrible future for the planet

Or rather, the very problem of the availability of drinking water, which is turning into an increasingly scarce product every day, is becoming vitally important. Moreover, the importance of water on Earth and its shortage in international relations are discussed at top level and often in a conflicting way.

Currently, more than 40 countries are experiencing 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 planet's population. In developing countries, water deficit will increase by 50%, in developed countries - by 18%. As a result, international tension around the topic of water shortage will increase.

Contaminated water as a result of human activity

This is due to geophysical conditions and 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 is spent on 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, which has millions of tons of waste products and fertilizers flowing 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 polluted with agricultural waste and metals. In China, 550 out of 600 cities experience water shortages; Due to severe pollution, fish cannot survive in reservoirs, and some rivers flowing into the ocean simply do not reach it.

What flows from the taps

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

Chlorine is dangerous!

To avoid possible infection with any infection, the water is chlorinated, which does not in any way diminish the danger. 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 boiling, it does not have time to dissolve completely and combines with organic substances that are always present in the water. In this case, dioxins are formed - very dangerous poisons, superior in strength even to potassium cyanide.

Water poisoning is much worse 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, taking almost decades. Causing disruption of the endocrine system and reproductive functions, they destroy the immune system and cause cancer and genetic abnormalities. Chlorine is the most dangerous killer modernity: killing one disease, it gives rise to another, even worse one. After global chlorination of water began in 1944, epidemics of heart disease, dementia and cancer began to appear en masse. The risk of cancer is 93% greater than that of those who drink non-chlorinated water. There is only one conclusion: you should never drink tap water. The ecological importance of water is problem No. 1 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 is one of the most abundant chemical compounds on Earth. It covers about 4/5 earth's surface, and its total mass on the planet reaches 10^18 tons. Water not only plays a primary role in everyday life and industry, but is also extremely important for maintaining life in general. None of the living creatures on Earth can live without water. Such an important and direct role is due to its physical and chemical properties. It is difficult to overestimate the importance of water in human life.

Approximately 2/3 of the human body consists of water. As part of a living cell - the structural and functional unit of the body - it also occupies the first place in quantitative terms. The saturation of a cell with water is directly related to the intensity of metabolism in it.

The more water in the cell, the higher the metabolic rate. In what form can water be found in cells?

This chemical compound can be found in cells in free and bound form. Free water, partially filling the intercellular spaces, vessels, organ cavities and cellular vacuoles, serves for the transport of substances between the cell and environment. In bound form, water is found between protein molecules, fibers, membranes and is part of some cellular structures.

Properties of water and its functions in the body

Without water, it would be impossible to maintain the volume and elasticity of a living cell. In addition, the vast majority of chemical reactions in the body occur in aqueous solutions. The selective ability to dissolve and not dissolve certain substances, high heat capacity and thermal conductivity, incompressibility and other properties make water indispensable for life.

Water dissolves ionic compounds well - acids, bases and salts. This is explained by the polarity of molecules and the ability of water to form hydrogen bonds. Some nonionic but polar compounds, such as sugars, amino acids, and simple alcohols, also dissolve easily. All these substances are called hydrophilic (from the Greek hydros - wet, philia - inclination).

When a substance passes into solution, its reactivity increases significantly. For this reason, water is the main medium for biochemical reactions to occur. Many redox reactions and hydrolysis reactions occur with the direct participation of H2O.

An extremely important role is played by the solubility of gases in water - oxygen, carbon dioxide and others.

No less important for living organisms is the ability of water not to dissolve certain substances called hydrophobic (from the Greek phobos - fear), for example, fats, nucleic acids, some polysaccharides and proteins. Many chemical reactions take place at the resulting interface.

High heat capacity and thermal conductivity ensure thermoregulation of the body and protect against sudden changes in body temperature. Almost complete incompressibility determines the volume and elasticity of cells and tissues. The optimal value of surface tension makes capillary blood flow possible.

The role of water in Everyday life person

A person deals with water every day throughout his life. He uses it for drinking and cooking, washing, bathing and much more.

If you can live up to 50 days without food, then without water - no more than 5. Severe dehydration can lead to fainting and hallucinations. In the end, such a state without rendering medical care ends fatally.

Thirst is often disguised as appetite. If you're craving a snack, simply drinking water is often enough.

Water is essential for normal thinking and physical activity. With sufficient fluid intake, a person is resilient and energetic. Dehydration leads to fatigue, poor concentration, headaches and joint pain, increased blood pressure, and kidney problems. Lack of moisture in the body also affects the condition of the skin: it becomes dry and more prone to wrinkles.

You should not limit yourself to drinking; it is healthier to drink little and often. If you drink a lot of water at once, the excess liquid, being absorbed into the blood, puts unnecessary strain on the heart until it is excreted by the kidneys. Organizing the right drinking regime helps maintain health and is the key to longevity.
