Water in the human body is from fifty to eighty-five percent of its weight. A significant shareholding, isn't it? If a person is what he eats, then surely a person is what he drinks! The role of water in the human body is great!
Water in the human body. The amount of water in the human body
Water in the body of an adult is about 65% The body of a monthly embryo consists of 97% water, a newborn baby - 75-80%, in older people the water content in the body is 57%.
The percentage of water in the human body throughout his life balances approximately in the same boundaries.
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, forty percentage solution caustic sodium.
It is not difficult now to calculate how much water your body contains if you know your weight. The younger and more energetic the human body, the more fluid it contains. This means that with the help of a certain drinking regimen, you can significantly improve your well-being and appearance. With proper use, our friend, water is able to restore and maintain youth, health, performance.
WATER IS THE MOST DAILY USED PRODUCT ON THE PLANET!!!
Water is the source of life and the guarantee of youth. Water makes up more than two-thirds of a person's body weight. Without water, a person dies within a few days.
Water in the human body. The content and distribution of water in the human body
The distribution of water in the body is uneven. The human brain contains the most water - it consists of 95% water, blood - 82% and lungs - 90%. Dehydration of the human body by only 2% causes painful symptoms, which indicate a drop in the body's water supply: fuzzy short-term memory, problems with basic mathematics, difficulty focusing on small printed characters, such as those on a computer screen. Are you having trouble reading this? Drink!
"I'm dying of thirst!" The problem is that a person cannot always recognize the signs of thirst. Mild dehydration is one of the most common causes of daytime fatigue. Experts estimate that seventy-five percent of people have mild, chronic dehydration. Pretty scary statistic for a developed country where water is readily available through a faucet or water bottle.
Water plays an important role in the mechanics of the human body. The body cannot work without it, just as a car cannot work without gas and oil. In fact, all cells and organ functions that make up our entire anatomy and physiology depend on water for their functioning.
- Water serves as a lubricant.
- Water is the basis for saliva.
- Water forms the fluid that surrounds the joints.
- Water regulates body temperature, as cooling and heating is distributed through sweat.
- Water helps relieve constipation by moving food through gastrointestinal tract and thus eliminate waste - water the best remedy body detoxification.
- Water helps regulate metabolism.
Drink water, wash away ailments and worries! Use water as a sure remedy for health and youth!
How much water is in the human body? "A living organism is animate water." Biologists sometimes joke about this, that water "invented" man as its means of transportation.
How much water is in the human body, we already know. Many! Plants that serve as food for man contain even more water than human body- 90%. Each cell of a living human body is water, which is presented as a solution of nutrients.
- How much water does the human body need per day to replenish its daily reserves and keep water balance organism in perfect order?
In addition to the daily maintenance of our bodies, we need drinking water. Approximate rate daily requirement drinking water for a person - eight glasses!
Water is also significant tool in disease prevention. Meeting the daily requirement of drinking water can reduce the risk of colon cancer by 45%, cancer Bladder by 50% and it could potentially even reduce the risk of breast cancer. And these are just a few examples! Water can help in the prevention and treatment of many types of diseases, illnesses and disorders that affect many systems in our body.
Since water is so important component our physiology, it would make sense to monitor the quality of the water consumed, and not just its quantity. Drinking water must be kept clean and free of contaminants at all times to ensure proper health and well-being.
"Do not drink ( dirty water)! You will become a goat…”
Remember! Man is what he drinks!
In the body of an adult, water makes up 60-70% of the total body weight. The higher the content of the fat component, the lower the water content. Conversely, the higher the percentage of active body weight, the greater the water content in it. The water content in different tissues is not the same. In the connective and supporting tissues, it is less than in the liver, spleen, where it is 70-80% ( table 17).
Water goes to organism in the form of liquid (48%) and in the composition of solid food (40%), the remaining 12% are formed during metabolism nutrients. Since women have more fat in their body weight, they also have almost 10% less water than men. The body of a lean person contains up to 73% water, which is considered very constant. This water is usually divided into intracellular fluid and extracellular. Intracellular fluid is 40%, extracellular - 20% of body weight. 15% of the extracellular fluid is in the lymph, synovial, cerebrospinal fluid and serous fluid. The share of intravascular fluid accounts for 5% of water. It contains plasma water and erythrocyte mobile water, which is interchanged with plasma water. With dehydration (dehydration), erythrocytes lose part of the water, and with an excess of water in the plasma, they take some of it. With dehydration, blood thickens and microthrombi occur. Therefore, it is dangerous to limit oneself in fluid intake when visiting a sauna (bath), during training (especially during competitions) in a hot and humid climate.
Determining the volume of fluid in the composition of the body is extremely important for the athlete. The measurement (determination) of the total mass of water is carried out by the radioisotope method (tritium, bromine82 and other radioisotopes). The total water content can be determined by the formula of E. Osser-manetal. (1950):
% total water = 100 x (4.340 - 3.983/d)
where d is the specific weight of the body. E. Osserman et al. (1950) noted that the body of healthy men aged 18 to 46 years contains 71.8% of water. E. Mellits A.D. Cheek (1970) proposed an equation for calculating the amount of water and fat in the body based on anthropometric data. They examined people aged 1 to 34 years and established a linear relationship between the water content (in l) in the body and body weight (in kg):
- for men, total water content = 1.065 + 0.603 x (body weight);
- for women, total water content = 1.874 + 0.493 x (body weight).

- for men whose height is more than 132.7 cm, total water content = -21.993 + 0.406 x (body weight) + 0.209 x (height);
- if a person's height is less than 132.7 cm, then the total water content in his body \u003d 1.927 + 0.465 x (body weight) + 0.045 x (height);
- for women whose height is more than 110.8 cm, total water content = -10.313 + 0.252 x (body weight) + 0.154 x (height);
- if height is less than 110.8 cm, total water content = 0.076 + 0.507 x (body weight) + 0.013 x (height).
Thus, studies with the measurement of various anthropometric indicators in people involved in physical education and sports make it possible to control the growth and development of their physical performance. From the point of view of health, the assessment of the state of muscles and posture is of particular importance.
Have you ever wondered at your leisure how much water is in the human body? Quite often it happens to hear from various sources that the amount of this liquid reaches 90% or is close to it. It turns out that this information is not entirely accurate, since various people the percentage of water in the body is not the same. Affects the amount of H 2 O for several significant reasons. This is the age, gender of a person, body composition, health status.
The story of how much water is in the human body can be started with specific numbers. In adults, the percentage of water in the norm is from 55 to 70 percent. It is distributed unevenly in the organs. The least liquid contains bones. There it is only about 32 - 35%. The largest number H 2 O contains the brain. In this organ-thinker, the amount of liquid reaches 90%. It is approximately 80% in the blood.
She is not just spills in pure form. Most of it (about 70%) is distributed inside the cells. the rest part of the fluid is called extracellular. It is part of the blood (plasma), lymph.
The amount of water in the body is not the same in people of different ages. During the period when the embryo is just beginning to form in the womb, it consists of more than 90% of this beneficial fluid. By birth, its number is significantly reduced. Newborns have approximately 80% H 2 O of body weight.
Also decreases the amount of this fluid in the elderly. They have this number close to 55 - 57%.
Affects the percentage of water in the human body and our weight,
body type. It is a mistake to think that the more a person weighs, the more water there is in the body. Everything is just the opposite: the fatter people are, the more adipose tissue they have, the less it is in the cells. Lean, lean people have about 70% of this fluid in their bodies.The human body is not so simple. Nature decreed that this colorless liquid, located in the human body, performs so many functions:
- Participates in metabolism
- Is the building material for our cells
- Dissolves solids
- Saves us from toxicity
- Removes unwanted substances
While in healthy body enough H 2 O, few people think about what can happen if fluid loss is suddenly detected or there is an excess of it. Non-compliance with the norm is always bad for the body, since each state gives rise to its own ailments, and sometimes very serious illnesses.
As soon as the percentage of water in the body rises, edema appears. This does not mean that a lot of liquid was drunk during the day, but indicates that some organ is not doing its job. Most often, the cause of the development of puffiness are diseases of the kidneys, heart.
Often the percentage of water in the body decreases, that is, descends below allowable rate. This leads to dehydration. The first signs of such trouble:
With persistent dehydration, a number of chronic diseases. You can avoid them if you use the prescribed daily number liquids, but there are no exact indications here, since each human body has its own characteristics. First of all, weight should be considered. Approximately 30 mg of fluid per day is required per 1 kg of body weight. This amount of consumption increases slightly on hot days. People engaged in physical work drink more fluids, as the body spends more of it. Individuals with kidney disease or hypertension should consult a physician regarding use the amount of liquid they have per day, so as not to harm yourself.
Many have heard that a person is 80% water. But how many percent of a person consists of water, in fact,. Everyone is familiar with the state of dehydration that develops in the body in summer, when it is hot, and when intestinal infections such as cholera and dysentery. So how much water is in the body, really? Here's what the researchers think about it.
How many people are made up of water
In fact, the ratio of water and other substances in the body depends on age, climate, time of year, the amount of liquid consumed during the day, and many other factors. What percentage of an adult is made up of water – it's about 60%. However, this rule is not absolute. If healthy man At the age of 40, the figure ranges from 62% to 70%, while in an elderly person this figure decreases and is about 50%. However, a lot depends on the state, weather conditions, the amount of liquid consumed, salt and many foods, and the state of health. But in an embryo, the body consists of 97% water. The amount of this fluid in the body of a newborn is 90%, in a child of 5-7 years old - 80%. However, how much a person consists of water in adulthood depends on:
climatic conditions;
The ratio of liquid to salt in water. If a person consumes water and salty foods, then salt retains fluid in the tissues, and its ratio changes;
From weight - the more it is, the more water can be in the body;
From the amount of fluid consumed and the speed of metabolism;
From the season. In summer, dehydration occurs faster, especially if a person is in the sun a lot;
From diseases. With some diseases in the body, water becomes more or less than normal;
From physical stress. After taking a bath, visiting the fitness room and any physical work a person needs to restore the balance of water in the body.
There are other factors that affect the percentage of water in the body.
Why does the body need water?
This liquid is involved in all metabolic processes, and it does not matter how much a person consists of water. If it is not enough in the body, thirst appears, and a person simply needs to find water somewhere or drink another liquid. Usually, experts advise drinking as much as possible during the day, since it is water that removes various toxins from the body, especially during illness. If a person begins to consume less ordinary, simple water, without additional substances than necessary, then he becomes ill, begins to age prematurely, and may even get a heat stroke. Most of the water in the body is found in the brain, blood, and excretory system. A lot of it in other tissues. An indicator that there is not enough fluid in the body is not only thirst, but also bad condition hair and skin. After you have drunk even a little water, you feel much better.
Therefore, for health, it does not matter how much a person consists of water, the main thing is to drink enough of it throughout the day. However, you should also consume little salt so that excess fluid does not linger in the tissues. Otherwise, toxins will spoil the microflora of the body, causing disease.
So, the average indicator of how many percent of a person consists of water is 60%. But . It all depends on the weight, age and height of the person, the time of year and other factors. The main indicator that there is enough water in the body is the lack of thirst. If it is, it means that the body does not have enough water and it is urgent to fill its deficiency.
Everything in our World has a foundation - a foundation. It would never occur to anyone to doubt, for example, the fact that the quality of the foundation of a house during construction completely determines its performance characteristics in the future: resistance to earth vibrations, on which the integrity of the entire structure - walls and roofs - depends. From this, in turn, depends the period during which the house will be suitable for life and generally will stand. Also, almost every person, especially those who have a summer cottage, knows that the stability of trees depends on how developed they are. root system. However, almost no one thinks about what the human body is based on. But this knowledge is the basis of our health.
In this article, I want to highlight in detail a topic that everyone seems to have heard about, but very few people understand it: a person is water. After a person truly realizes this simple fact, he takes the first step towards longevity and a fulfilling life.
Man is made up of water
Water is the basis of the human body. Let's first look at the dry medical facts and see how many percent of the body consists of water:
- The body of the embryo consists of 97% water.
- A newborn child - by 90%.
- A child aged 5-8 years - by 80%.
- Body healthy person middle-aged consists of 65-75% water.
Note the trend in body water content as age increases. We will return to it a little later.
I will add to this information data on the water content in organs, tissues and body fluids:
- The brain - 75-81%.
- Bones - 22-30%.
- Cartilage - 60%.
- Muscles - 50-75%.
- Kidneys - 83%.
- Heart - 78%.
- Lungs - 83%.
- Skin - 60-70%.
I will not now list all the statistics of the percentage of water in each connective tissue and parts of the body, because the table will be very large. If anyone wants to see the full data, they can be found in specialized medical reference books. Now I have listed only the basic indicators.
Now for some math.
What is the mass of water in the human body (in kg)
The level of mass of water in the human body is influenced by many factors: climatic conditions, level physical activity, daily intake water (namely water), age, lack or excess excess weight and a whole lot more. For the calculation, I take the average statistical data for the female and male body middle-aged, average height and average body weight (for residents of Russia).
— Mass of water in the female body (kg)
Average weight healthy woman, depending on height, is 55-60kg. After calculations, we find that the average water content in a woman's body is 38-39 kg.
— Mass of water in male body(kg)
The average weight of a healthy man is about 75-80kg. The final water content in the body of a man is approximately 53-57 kg.
Carefully look at this data. Reread them several once. Realize these numbers.
Above, I drew your attention to the age trend of decreasing the percentage of water in the human body. Let's talk about this in more detail.
The DNA of our body has a program for the optimal water content for each organ, each fluid, each tissue, etc. Human body It is fully formed and develops its functions by about 14 years in girls, and by 17 years in boys. It is this age that is the standard in terms of health. This is noted in numerous Russian proverbs and sayings. Let me give you one of the most frequent, which is on everyone’s lips in our time: “Eh .. Where are my 17 years old?”. People who say this phrase do not even think about why this particular age is mentioned in it. Not 10 years, not 20 and not 25, but exactly 17. I will not overload the article with physiological details of why this is so. In short, I can only say that by this age a person has a fully formed skeleton, muscle structure, they have completed their formation and growth. internal organs, fully developed reproductive system etc. In these years, the water content in the body is the most optimal. As a result, teenagers have maximum vital activity and energy. By the way, that is why in many sports the peak of career and sporting achievements falls precisely on the period of 16-20 years.
It's no secret that the culture of modern food is far from ideal. A person eats food that is unusual for him, began to consume a lot of chemical products (especially in last years) - soda, chips, sausage, which is 100% a product chemical industry, a lot of chemically processed vegetables and fruits appeared, and much more. I will talk about this in detail in a series of articles about proper nutrition. How longer man eats the wrong food, the more toxins and toxins accumulate in his body. The body becomes clogged, loses the opportunity fully absorb water, its percentage in the body is constantly decreasing. All this leads to what people call “aging”.
Aging is not some kind of program embedded in human DNA, as in Lately scientists often like to talk. They are looking for some kind of “ageing gene”, trying to somehow stop it or slow down its action in order to extend life expectancy. All this is complete nonsense. Aging is nothing more than a gradual decrease in the amount of water in the body.
Man is a part of Nature. Everything on our planet, one way or another, is tied to water. Even things that are not alive. Without water, the Earth would turn into a soulless desert.
At the beginning of the article, I gave an example of how important the foundation is for a house. Let's continue this question. What is the difference between old and new houses? I'm not talking about construction technologies that are constantly evolving. This is clear. Let's now take two houses built with the same materials and look at the new house and the old one. The connecting element in the construction of a house is cement. It is also the basis of the house along with the foundation. The basis of cement, among other things, is water. If there is no water in the cement, then it is an ordinary building powder with which nothing can be done. But when water is added to it, it acquires the function of binding building materials. In the new house, the cement is also new - it has the right amount of water. And what do we see in the old house? Over time, cement loses water, begins to dry and crack. As a result, the walls crack, the house loses its integrity and strength, and as a result collapses. Go outside, find an old one (at least 40 years old) and new home look closely at the cement. The new one will look solid, and the old one will have cracks. Everything is obvious.
Water in our body performs approximately the same functions - water revives our body and makes it basically alive . Without quality water in necessary quantity our body cannot manage and live by definition. All mechanisms of vital activity of the body are based on water, one of the main of which is the mechanism of regeneration. It is the regenerative abilities of the body that determine the level of health and life expectancy. Death occurs when this mechanism stops its activity.
How many days can a person go without water
The body can get by without food long time. The first officially recorded world record was set by Arnold Ehret, whose books I so often mention in articles. He was the first under the supervision of scientists to go completely without food for 49 days. However, he drank water. From religious literature one can read about monks who, spending their time in prayers and spiritual labors, did not eat for years, but only drank water.
With water, things are different. average modern man can do without water for about 7-8 days. Trained (who regularly practices fasting and cleansing the body) - up to 14 days maximum. This clearly demonstrates the fact that water is the basis of human life, and not food at all. From food, the body receives the building materials it needs, and nothing more. Moreover, the body has a mechanism that allows it to do without food at all - symbiotic bacteria in the intestines can synthesize any substances that the body needs. This level of health (cleanliness of the body) is extremely difficult to achieve, but it is real. But even in this case, the body needs water.
Think about what is written.
So, in this article we have analyzed the general, but very important concept: the basis of the human body is water. Water is the main construction material our body. And the vast majority of people simply do not pay attention to this simple and extremely obvious fact. This is precisely the reason for disease and short life expectancy in modern society.
In the next article, I will talk about exactly what role water plays in our body, and why the body needs it at all.

Hello Elena. I don't quite understand the word "creatures".
To answer
Hello. Tea is not water. Moreover, in large quantities it is extremely harmful. The body needs H2O.
To answer
Vladimir, hello! Please tell me if there are creatures on our planet water drinkers in enough and living much longer than average good quality life?
To answer
Water appears inside a person even in the womb. But it does not appear in a child from outside and not from the mother. The water from which a person consists is different, it is alive. It is born along with a spark of life inside a little man.
The water of which a person consists is a liquid crystal on which all information about a person is recorded. The water that is used from the outside carries information about the outside world. (small amount) to purify the body. Due to this internal resources end and the person dies. During dry hunger, the person’s water leaves and purity is felt in the mind due to the reduction, erasure of the prescribed algorithms and programs in it.
Water on Earth is water from people who once lived on it. The salt of the earth is literally the remains. Salt and water. As well as all the other minerals in the Earth. Man created the Earth. The human body and the Earth are one and the same. Man creates everything that surrounds him through his body. Chemical elements are produced by man.
Good health. Thanks for the article. Question: Do you need to drink only water? I have a predisposition to green tea, I drink it during the day, it just comes out 2; 2.5 liters (with water)
