What happens if you drink water often. What happens if you drink a lot of water? Harm and benefit of water. Water-salt balance: optimal level

Water is extremely important for the human body and its main component. The metabolic processes in humans are arranged in such a way that if the body lacks fluid, the metabolism stops. Water is also involved in the regulation of body temperature.

Even a slight lack of fluid can lead to disruption in the work of all organs and systems, including the central nervous system. With a lack of water, a person becomes irritable, weak both physically and emotionally.

At the end of the article, we have prepared a surprise 🎁 - an exciting test to test your attentiveness 😃

The human body is approximately 70% water. It is found in every cell of the body. Its entire volume falls on the intracellular fluid, 30% - on the intercellular fluid. Adipose tissue in the human body is 29% water, the bone skeleton is 22%, blood is 83%, and the eyes are 99% at all. Water plays an important role in the coherence of the gastrointestinal tract and maintains the correct level of blood viscosity. Together with sweat, it removes harmful products of mineral and protein metabolism from the body.

Water-salt balance: optimal level

No matter how depressing it may sound, a person can live without water for no more than 5 days, while without food, taking into account fluid intake - 25. Depending on individual features body, the norm is 2 liters of water per day.

Of course, the amount of fluid consumed is directly related to the climatic conditions in which the individual lives. The higher the temperature, the greater the natural moisture loss. Accordingly, more water is required for intake.

In addition, the type of activity and hobbies of a person are directly dependent on the amount of moisture consumed: with moderate and strong physical activity, for example, systematic training in the gym, you should consume at least 3-5 liters per day.

A lethal outcome from a lack of water is possible with a deficit of 25% of fluid from body weight. However, even in such critical situations death can be avoided by reducing fluid requirements to 10%. In this case, the body will slowly but surely recover.

Interesting!

The feeling of hunger can occur with intense thirst: the level of glucose in the blood rises, which leads to the appearance of this feeling.

Strong thirst: causes

The feeling of thirst is a natural reaction of the body to changes in the water-salt balance. Appears during active physical exertion, the use of fatty and salty foods, as well as at a high temperature of the environment in which the person is located. A constant and unrelenting feeling of thirst may indicate the presence of systemic diseases. It is formed by receiving the appropriate signals from the drinking center in the brain. In turn, it is influenced by:

Cortex;
limbic system;
Hypothalamus.

Disturbances in the functioning of these areas of the brain, as well as defects in the drinking center itself, cause an unreasonable feeling of thirst. A constant desire to drink can be caused by the following conditions and diseases:

Poisoning;
chronic diarrhea;
Hyponatremia;
Adrenal adenoma;
kidney failure;
Diabetes.

The feeling of thirst can also be caused by some medications of various effects.

Consequence of excessive water intake (hyperhydration)

Hyperhydration occurs when there is a lot of water in the human body. This can lead to swelling on the face and legs, as well as ascites with swelling of the lungs and brain. A large amount of water in the body leads to an increase in the load on the kidneys and a violation of the water-salt balance. In this case, the liquid turns from vital important component into ballast, so it is not recommended to drink too much water.

Interesting!

Overhydration can occur in conditions requiring gastric lavage, such as poisoning. In this case, the medical staff pours up to 10 liters of water into the human body through the esophagus. Specialists simply do not allow the body to enter a state of hyperhydration.

Symptoms and treatment of overhydration

Symptoms of overhydration include:

Spasms in the muscles;
Feeling of nausea, vomiting;
Diarrhea;
General weakness;
Loss of consciousness.

Treatment in case of hyperhydration should be timely: to correct the condition, hemodialysis is used - an apparatus that contributes to the normalization of metabolism. Diuretics are prescribed - diuretic drugs. When hyperhydration plays an important role proper nutrition: Foods eaten should not be high in sugar and salt. Alcohol is prohibited during treatment. Alcohol, as well as excessively sweet and salty foods, contributes to the retention of moisture in the body.

There is an opinion that if you drink 5 liters of water, a person will not suffer from overhydration. However, it is worth considering the individual characteristics of the body: for someone, even such an amount of water, taken in a short time, can be fatal.

The volume of food and liquid entering the body is directly related to the weight of a person. If you drink too much water, swelling of the body may occur, so you should not get carried away with drinking plenty of water.

Proper drinking for weight loss

To get rid of faster excess weight, you need to follow a few simple rules:

In the process of losing weight, only pure water is taken into account: tea, coffee, juices are not taken into account. In addition, coffee completely leads to dehydration, working as a diuretic. It is worth remembering that after a cup of this drink you need to drink a glass of clean water;
Drinking water in the morning on an empty stomach will speed up your metabolism, which will positively affect the process of losing weight. Often in morning reception cinnamon, mint, honey or lemon are added to the liquid;
Drinking water before eating will help reduce hunger and improve the functioning of the digestive tract. A person often confuses simple thirst with the desire to eat;
For drinking, it is important to use only clean water that does not contain life-threatening components;
It is worth drinking liquid in small sips: this minimizes the load on the kidneys and the feeling of thirst passes faster;
Between the established time of consumption of food in the period of weight loss, hunger often occurs. Drinking water in such cases will help reduce its severity.

Carbonated water: benefit or harm

There is an opinion in society that if you drink a lot of carbonated water, then problems begin with three organs and systems at once: the gastrointestinal tract, the bone skeleton and tooth enamel. Let's find out if this is true.

Gastrointestinal tract

Soda is obtained by adding pressurized carbon dioxide to ordinary mineral water. If you drink too much of this water, you may experience hiccups and indigestion. However, there is evidence from studies in which it has been proven that the use of carbonated water for diseases such as constipation and dyspepsia leads to an improvement in the condition.

Who just does not advise us to drink a lot of water. It can be nutritionists and fitness trainers, cosmetologists and doctors, friends and family. But many still have the question: "If there is water, what will happen?" Today our goal is to figure out what water gives the body, how much it needs to be consumed and how its excess or lack affects its condition.

First of all, people who dream of losing weight decide to drink more water. With the help of water, they try to fill the void in the stomach and satisfy the feeling of hunger. But in fact, water is necessary for the body like air. Often people say they don't drink much because they don't want to. In fact, we are simply not used to drinking water. More often we consume sugary drinks, juices, tea or coffee. But, as nutritionists say, only water can quench your thirst. Juice, milk and other liquids are food, but coffee and tea are poison. And yet, if you drink a lot of water, what will happen? Will it benefit the body or, conversely, cause deviations in its work?

A bit of physiology

Water is the basis of life on earth. All biochemical processes in the body are associated with water metabolism, moreover, the human body itself consists of 80% of water. In order for the body to function like a clock, it needs a certain amount of clean water. How much is a somewhat debatable question. The greater the body weight, the higher the need for it. For a person weighing 50 kg, 1.5 liters per day is enough, and if the weight is within 80 kg, then it is advisable to drink about 2.5 liters. The number sounds big enough that people start to wonder: "Will I be able to drink that much liquid, and if I drink a lot of water, what will happen to me?" In fact, this happens because we are not used to drinking water, but in vain. Due to constant dehydration, skin and hair problems begin, worsen chronic diseases heart and intestines, metabolic processes are disturbed. Even the smell of sweat with a lack of fluid in the body becomes different, sharper and more piercing, due to an excess of toxins.

There are a few more points that affect our need for fluid. It's the temperature environment. The hotter it is outside, the more moisture the body loses. The second point is physical activity. So, an office worker will need less water than a builder.

The role of fluid in the body

Water is the basis of our existence. It dissolves substances in the body, delivers nutrients to the cells, removes toxins from the body. Therefore, your body will only be better off if you drink plenty of water. What will happen to the kidneys is a separate issue that worries most people. We answer: if you do not suffer from serious diseases of these organs, then a large amount of clean water will only benefit. In all other cases, you need to consult a doctor.

Very much the need for water depends on what we eat. If you are a lover of spicy salty foods, convenience foods rich in preservatives, then you really need to drink plenty of water. The more junk food you consume, the more resources your body spends to flush out all the toxins and waste. If you care about your health, then switch to healthy food. Vegetarians are allowed to reduce their water intake to 1-1.5 liters per day. By the way, the amount of water consumed directly depends on the abundance of your meals. If you are used to eating a lot, then you need to drink a lot.

You may be surprised, but almost half of all diseases occur because the body does not have enough plain water. So that your joints do not creak, stones are not deposited in the kidneys, and the skin is not too dry, you just need to make it a rule to maintain a normal level of fluid in the body.

How does water loss happen?

Water is used for all life support processes. It's not just about urination. Together with breathing and sweating, we also release precious moisture. In a day, the body loses about 2 liters of fluid in this way, which it must replenish. Soups, compotes, and other foods, of course, contain a liquid part, but it has a different structure and will not replace plain water. It is harmful to drink a lot of water only if you have direct doctor's contraindications, in other cases you should at least block the daily fluid loss. Dehydration is a serious condition that undermines the work of its protective mechanisms. Especially occurs at times of severe vomiting or diarrhea, elevated body temperature. At such times, water consumption should be as high as possible.

What happens to the body when there is not enough water

We cannot live without water. Even the breathing process, which seems to be autonomous, requires a large number fluid that moisturizes the lungs. Only for this you need about 0.5 liters per day. It should be taken into account that the exhaled air contains moisture, which increases the body to 0.7 or 1 liter, depending on physical activity. If the fluid is not renewed, then the breathing process is difficult. Add to this the costs of the excretory system (sweat and urine), replenishment of the liquid part of the blood, and you will understand that you need to drink plenty of water.

Eating too little of it contributes to the accumulation of decay products and toxins in the body, the formation of excess fat, can cause poor muscle tone and deterioration of performance. digestive system. Lack of water greatly increases which can lead to a decrease in blood pressure and the formation of blood clots. That is, the question of why drinking a lot of water can be answered very easily: for the body to fully function.

Separately, we can say about the relationship of the fragile beauty of a woman with the consumption of a sufficient amount of liquid. Now you will understand why you need to drink more water. Smoothness and good skin color, condition and hair growth depend on this. With a lack of clean water, wrinkles form much faster, dry skin increases, and hair loss increases.

moderate degree of dehydration

Many people do not even think about such simple things. Why drink a lot of water, because you can eat soup, an apple, drink juice - and the body will get everything it needs. The majority thinks so. This is a big misconception, because nothing else can replace clean water. If a person does not drink enough water, then dehydration occurs. And most of us are constantly in this state. The first symptom to look out for is thirst. Getting used to drinking little, we can not pay attention to it for a long time, especially if we are very busy at work. In this case, the body turns on the economy mode. Sweating decreases and urination decreases. You can work all day and never have to go to the bathroom. However, the body works in emergency mode. To compensate for the decrease in moisture reserves, the body begins to remove fluid from the cells. So water enters the blood, maintains at the proper level arterial pressure and replenishes the supply of lymph.

The next symptom of mild dehydration can be a headache, especially at the end of the day. This is how the brain, which consists of 90% water, reacts to changes. Those who say that it is harmful to drink a lot of water are greatly mistaken. As you can see, everything is just the opposite.

Severe degree of dehydration

Now we will tell you what happens to the body if you continue to live in the same mode. We hope that this will become a strong enough argument that will explain why you need to drink more water. If you drink less than a liter of water every day (not counting soups, coffee, tea and spirits), then the subsequent dehydration can lead to disruption of the functioning and condition of the kidneys, liver and heart. The extreme degree of dehydration of brain cells is the hallucinations that a person sees in the desert, but it is difficult to bring oneself to such a state in urban conditions.

Prevention of water deficiency in the body

To do this, it is enough to go to a general practitioner who will confirm that you can drink plenty of water. Many are afraid of edema, but in fact they are a sign of serious illness or an attempt by the body to stock up on fluid for future use. If you consume enough water every day (for adults, this figure starts from 8 glasses, increasing if you need to do heavy, physical labor, hot weather outside), then the excretory system will work like a clock. This means that the metabolism will go correctly, and excess fluid will be removed from the body in time, removing toxins and decay products.

Why is the question still relevant, is it harmful to drink a lot of water? Because its quality in many regions leaves much to be desired, and also because of the prevalence of severe kidney disease among the population, in which a water-salt diet is indicated.

How much water can you drink per day

Most people live permanently in a state of dehydration and don't even know it. However, to prevent harmful effects for the body can be very easy. To do this, just drink 8 to 10 glasses a day. To avoid unnecessary stress on the kidneys, you need to distribute this amount throughout the day and do not lean on water before bedtime. Of course, this is a relative norm. It depends on the lifestyle, the quantity and quality of food consumed, the time of year. But in general, the question of whether it is harmful to drink a lot of water can be answered unequivocally: no. This should not be taken as a guide to drinking as much water as possible. For more accurate calculations, you can use the formula - 30 ml per day for every kilogram of weight.

Water for weight loss

Girls and women pass this rule on to each other: if you drink a lot of water, you will lose weight. In fact, water itself does not have fat-burning properties, is not able to prevent the absorption of consumed fats or break down those that have already been deposited in the body. But it is a good helper for those who decide to lose weight.

To begin with, water serves as a filler for the stomach, it has no calories, but it allows you to pacify your appetite and eat less at dinner. To do this, nutritionists advise drinking one or two glasses 15 minutes before each meal.

Other sources of liquid

Caffeinated drinks (tea and coffee) should not be used to quench thirst. Soda found in soda, coffee, beer and stronger alcoholic drinks lead to dehydration. Their use leads to increased depletion of water reserves in the body. With regular use of them instead of water, heartburn, pain in the abdomen, in the lower back, headaches and depression will be observed. Do you still doubt whether it is useful to drink a lot of water? Try a few months to use the prescribed amount of it instead of the usual tea. And watch your body.

Proper nutrition

If you eat enough fresh vegetables and fruits (at least 5 servings per day), then you can slightly reduce the amount of water you drink per day. These are the products that give the body precious moisture in desired form. The more your diet differs from healthy, that is, the more flour, fried, fatty, semi-finished products it contains, the greater the need for clean water. You can be sure that drinking plenty of water is good for you. All leading experts and nutritionists repeat this.

Water is the main element of the chemical constituents human body. She participates in the exchange processes. If there is no fluid in the body, the human body will not be able to work, the process of removing metabolic elements will be impossible. In addition, the thermal balance of the body is disturbed. Life parameters are significantly reduced even with a slight lack of water. Dehydration of the body negatively affects the nervous, mental activity of people. The impossibility of taking water for a person contributes to his irritation and oppression, fatigue increases faster, strong-willed and moral qualities weaken, and working capacity decreases. Therefore, a person needs to drink a lot of water.

Water in physiology

The percentage of water from a person's body weight is 70%. Human cells, regardless of their functions, are a kind of microcosm. It carries out a large amount of complex and ordered transformations.

Water is the carrier of elements, both inorganic and organic. They are involved in many life processes. The intracellular fluid takes on about 70% of the total volume of human water. Interstitial fluid is about 30%, which is approximately equal to 12 liters.

Water content in tissues and organs of the human body

Let's figure out why a person needs to drink a lot of water. Tissues and organs have the following water content:

in adipose tissue - 29%;
in the eye - 99%;
bone skeleton - 22%;
blood - 83%.

Water is needed for normal digestion, assimilation of useful elements, removal of harmful substances, good blood circulation. That's why you need to drink a lot of water.

How much liquid is needed for water balance

At high air temperatures, a person can live no more than five days. To create a normal water balance, a person should drink about two liters of drinking water every day. This is the answer to the question, why drink a lot of water. Its volume is needed to maintain human life at the required level. It depends directly on the ambient temperature. If the temperature outside is 32 degrees, you need to drink 3 liters of water per day, at 20 degrees, 1.5 liters is enough. With moderate physical activity, it is advisable to drink at least 5 liters of water per day.

If you work outdoors, the volume of water can be increased to 6.5 liters. Fluid loss of up to 25% of total body weight can lead to death. Metabolic processes quickly normalize if the loss of water is not more than 10% of body weight.

Is it necessary to drink a lot of water, and where does water go in the human body?

1.5 liters is excreted through the excretory system;
0.6 liters comes out with sweat through the pores in the skin;
0.4 liters is spent during breathing;
0.1 liters leaves with a bowel movement with feces.

Why do you want to drink a lot of water? Hunger appears in people from the action of a small amount of glucose in the blood. High glucose and salt parameters make the body feel thirsty.

What Causes Strong Thirst?

This feeling is a natural human reaction to changes in the balance of salt and water. Thirst increases at high ambient temperatures, during exercise, after eating salty and fatty foods. When there is a constant thirst that occurs without the influence of the external environment, we can talk about the appearance of the disease. According to the standards, an adult man needs up to 3 liters of water per day, a woman 2.7 liters. The feeling of thirst is a signal coming from the drinking center nervous system.

Signals for the work of this center are given by:

cortex;
limbic part of the cerebral hemispheres;
hypothalamus.

Violations of the drinking center cause unreasonable thirst. It analyzes signals from human fluid organs, compares the level of pressure, the content of sodium ions. In this process, the hormones of the pancreas and thyroid gland work.

A constant desire to drink can be a sign of the following diseases:

vomiting, poisoning;
chronic diarrhea;
hyponatremia;
head injury;
adrenal adenoma;
pathology and disruption of the pituitary gland;
kidney failure;
diabetes insipidus;
internal bleeding;
diabetes.

Taking certain medications contributes to the appearance of a strong feeling of thirst, dryness in the larynx and mouth.

Thirst during pregnancy and in children

During gestation, the rate of water intake should be more. Why do pregnant women need to drink plenty of water? Doctors advise pregnant women to drink 0.3 liters more water than usual. The daily norm of drinking is not more than 2 liters. Thirst may increase in the last period of pregnancy due to the entry into the blood of a special protein produced by the liver.

During the development of the fetus in the womb, her kidneys are under great stress. In this case, thirst appears from the action of a hormonal substance - angiotensin.

The health organization has determined the rate of fluid intake per day for young children, depending on the total body weight. For children weighing up to 5 kg, the norm of water together with mother's milk is 0.8 liters. If the child weighs up to 10 kg, then the rate rises to 1 liter per day. The norm of water for children depends on age as follows:

up to 3 years - 1300 ml per day;
up to 8 years - 1700 ml;
up to 13 years - 1800 ml;
up to 18 years - 1.9 liters.

In too mobile children, the presence of great thirst is the norm. However, to prevent the occurrence of pathology, you need to do a study.

Finding the cause of thirst

To diagnose the causes of thirst, the doctor must find out the reasons, taking into account the peculiarity of the patient's diet, the number of urination per day, and the composition of the diet.

The following blood tests are carried out:

the level of density and general parameters of urine;
blood test for biochemistry;
concentration of potassium and sodium;
glucose level.

Based on the received data, the patient is sent to the doctor. At the doctor's consultation, you need to calculate the largest and smallest daily intake of water. Many factors depend on the characteristics of a person, his age and gender. You need to know that carbonated water and alcoholic drinks do not reduce thirst, but even increase it. Doctors do not advise drinking mineral water, which contains salt, to quench thirst. The best temperature for drinking is at least 22 degrees. Icy and cold water should not be used for drinking. Strong thirst comes from fatty and fried foods, as well as from pickles and spices.

Experts studying this problem at the present time have concluded that it is possible to take a large amount of water only:

athletes;
workers engaged in hard work with great physical exertion in the air;
people living in hot climates.

Scientists do not consider a large amount of water to be beneficial for the common man. Official treatments do not contain advice folk methods, which say that you need to drink 8 glasses a day. High water intake can cause sodium to be flushed out of the body. There is no official evidence that excess water has a positive effect on human organs. Excess fluid does not increase skin turgor, as cosmetics manufacturers say.

Why is it bad to drink a lot of water

Doctors in many countries argue that the daily volume of water should be normal. Advertising information about the large consumption of bottled water indicates an increase in sales. You need to listen to your body and not take extreme steps. If physical work sports training leads to a decrease in body weight, then it should not be replenished with increased drinking of water.

A large volume of water affects the following:

The functions of the digestive organs are deteriorating.
An increased load on the kidneys is formed, too much water is excreted through the kidneys, this leads to the leaching of salts.
The heart and blood vessels work with a high load.
Decreased muscle tone.
There is rapid fatigue, fatigue and muscle spasms.

Signs and causes of excess water in the body

Hyperhydration is a condition similar to water poisoning. Water accumulates in this case in human cells. The most common reasons for this are:

Simultaneous intake of water in a volume of 10 liters, for example, when washing the stomach.
When the excretion pathways by the kidneys are disrupted.
Insufficient work of the heart.

Signs:

muscle spasms;
loss of consciousness;
weakness;
vomiting, nausea;
diarrhea.

What is the danger of overhydration

This phenomenon can lead to the death of a person if medical assistance is not provided. To normalize the condition, doctors use hemodialysis and prescribe diuretics.

How to get rid of excess water

Excess fluid that has accumulated in some parts of the body is visible on the face in the form of swelling of the eyes. The main task is to identify these edema, and then treat. The daily norm of fluid intake is set by the doctor's advice. To do this, carefully compose the diet and reduce the intake of salt, foods with preservatives. Sugar and alcohol, along with salt, are the main products for edema. Doctors advise including diuretic foods in the diet - green tea, beets, celery and other herbs.

Plant fiber removes fluid from the body. You can reduce the amount of water and eat more vegetables and fruits. It is better to drink only clean water, and do not drink products with chemical content. Lack of vitamin B causes water retention and swelling in the morning. On the advice of a doctor, you need to choose a complex of vitamins.

Why drink a lot of water when losing weight

On an empty stomach, drink a glass of warm water - this brings the stool back to normal. When exercising, doctors advise drinking a little water. You need to drink it, as a person is usually used to, while following a diet. However, you need to know that water will not give a feeling of satiety, although it contributes to a smaller meal. You do not need to drink a lot of water before going to bed, as swelling will appear in the morning. Drinking liquids before dinner is strictly not allowed. The liquid washes away useful elements that serve to break down products in the stomach. Water should be drunk half an hour before meals. You should not drink foods if you want to lose weight.

Where does the body's water supply come from?

For people who are thirsty, doctors advise eating apples. 50% of the volume of apples comes into the body as water. Fruits and vegetables containing water are recommended by nutritionists to be taken in food. Common sources of water include oranges, melons, and watermelons. The most water-containing vegetable is cucumber.

During a hot summer day, thirst is quenched by a cold decoction of apple peel, as well as green tea. Lemon drink should not be cold, but at room temperature. Excess fluid, as well as its lack, affects the state of human health, disrupts the functioning of organs, and negatively affects the condition of the skin and hair.

Not today scientific research, which could prove the positive effect of a large volume of water on human health. You can not believe traditional healers, information in advertising, and other unreliable facts. Why drink a lot of water a day? You need to remember about logic and sense, as long as this will be a good teacher for you.

Water is the main chemical element of the human body, it takes part in all metabolic processes. In the absence of fluid, the human body is not able to function: the process of removing metabolic products becomes impossible, and heat balance cannot be maintained. Vital signs deteriorate sharply even with slight dehydration.

Dehydration of the organism negatively affects the higher neuro-psychic activity of the individual. The inability to replenish fluid reserves leads a person to a depressed and irritable state, a feeling of fatigue quickly progresses, moral and volitional qualities weaken, and work capacity drops sharply.

Water makes up 70% of an adult's body weight. Each cell of the body, regardless of the functions assigned to it, is a microcosm in which an innumerable number of ordered and complex transformations take place.

Water acts as a carrier of organic and inorganic elements involved in all life processes. The intracellular fluid accounts for 70% of the total water reserves in the body. Intercellular fluid is 30% (about 12 liters).

The amount of water in the composition of organs and tissues of the human body

blood - 83%;
skeleton - 22%;
vitreous body of the eye - 99%;
adipose tissue - 29%.

Water is vital for digestion, absorption useful substances, removal of toxins and blood circulation.

The required amount of fluid to maintain water balance

In a hot climate, a person can live without water for no more than 5 days. To maintain water balance, an adult needs to consume from 1.5 to 2.5 liters daily. pure water.

The amount of water required to maintain human life at the proper level directly depends on the ambient temperature. At 32 ° C - the daily rate is 3 liters; at 21 °С - 1.5 l; for 10 °С - 1.3 l.

During moderate physical work, it is recommended to consume at least 5 liters of water per day; working on the street or in the open air, you should increase the rate to 6.5 liters.

The loss of fluid leads to death, which is 25% of the total body weight. The metabolic processes of the body quickly return to normal if the loss of fluid does not exceed 10% of the total body weight.

1500 ml is excreted in the urine;
600 ml - through the pores of the skin in the process of sweating;
400 ml - in the process of breathing;
100 ml during bowel movements.

The feeling of hunger arises in a person under the influence of low blood glucose levels. An increase in salt and glucose levels triggers a thirst signal.

What is the cause of excessive thirst?

Thirst is a natural reaction of the body to changes in the water-salt balance. Thirst increases at elevated ambient temperatures, during physical exertion, after eating fatty and salty foods.

A state of chronic thirst independent of external factors anxiety symptom. Polydipsia - unquenchable thirst, acts as a sign of a latent disease.

Normally (according to WHO), an adult man needs 2.9 liters of fluid per day; adult woman - 2.7 liters.

Thirst is a signal that comes from the drinking center of the central nervous system. Responsible for drinking center:

limbic part of the cerebral hemispheres;
areas of the cerebral cortex;
nucleus of the posterior lobe of the hypothalamus.

Violations of the drinking center - the main cause of uncontrolled thirst. The center processes the signals coming from the liquid structures of the body and compares the level of osmotic pressure, the level of Na +. The process involves thyroid and pancreatic hormones.

Taking certain medications can cause extreme thirst, dryness in the mouth and throat. Among them: antipsychotics, diuretics and antibiotics.

Intense thirst during pregnancy

During the period of bearing a child, the rate of fluid intake should increase slightly. Doctors recommend that pregnant women consume 300 ml more water than the usual daily allowance, while the daily allowance should not exceed 2 liters of fluid.

Thirst may increase in the last trimester of pregnancy due to the entry into the bloodstream of a specific protein that is produced by liver cells.

During the period of intrauterine development of the child, the mother's kidneys experience additional stress. The hormone angiotensin provokes additional thirst.

Thirst in a child

The World Health Organization has calculated the daily fluid intake for young children based on total body weight.

For a 5 kg baby, the daily fluid intake (including mother's milk) is 800 ml.

For a 10 kg child, the norm increases to 1 liter per day.

Daily fluid intake for children depending on age

1-3 years - 1.3 liquids (of which 350 ml of milk, soups, juices, fruits);
4-8 years - 1.7 l;
9-13 years old - 1.8 l;
14-18 years old - (boys: 1.9 l, girls: 1.6 l).

In especially mobile children and adolescents, increased thirst is a normal phenomenon, but in order to exclude a pathological process, one should undergo an examination.

Diagnostics

To identify the causes of excessive thirst, the therapist must collect an anamnesis and take into account the peculiarity of the patient's daily regimen, the number of daily urination, and the daily diet.

If necessary, conduct laboratory blood tests for:

determination of plasma glucose levels;
osmotic concentration of potassium, calcium and sodium in the blood;
blood chemistry;
determination of the level of general indicators and the relative density of urine.

Based on the results obtained, the thirsty patient will be referred to the appropriate specialist.

How to deal with increased thirst

At a consultation with your doctor, you should determine the optimal and maximum daily fluid intake. Much will depend on the individual characteristics of the body, gender and age.

It should be remembered that alcoholic and carbonated drinks with additives do not weaken thirst, but, on the contrary, increase it. Mineral water saturated with salts is not recommended for thirst quenching. Optimum temperature water to quench your thirst - not lower than 22 ° C. Cold and excessively chilled water is not the best solution for severe thirst.

Strong thirst is provoked by fried and fatty foods, all kinds of spices and pickles.

Benefits of drinking plenty of water

Scientists conducting research in the 21st century have come to the conclusion that consuming excess water is only permissible for:

athletes;
people engaged in heavy physical labor in the open air;

What causes dehydration

If a person can live without food for a month or more, then without water - no more than three days. When an insufficient amount of fluid is consumed, the body switches to an economical mode of operation, extracting water from the skin, joints and providing water only to the most important organs. As a result of dehydration, you may experience the following problems.

We become more scattered, as brain cells are not sufficiently enriched with the necessary substances. Also, in a dehydrated state, fatigue is much more felt and stamina is lost.
