This means that the dehydration has gone too far. Therefore, it is important to drink water, and regularly - after all, the liquid drunk a few hours ago or in the evening does not count.

How is your daily water intake

affects the body:

• Toxins are actively eliminated.
• Skin condition improves.
• Decreases excessive appetite.
• The work of digestion is normalized.
• The metabolism is increased.
• Headaches are neutralized.
• The likelihood of seizures decreases.
• The state of the immune system improves.

Water is the source of life not only for humans, but also for the entire flora and fauna of the Earth. Therefore, it is not worth explaining how important the effect of water on the health and growth of a living being is. Lack of drinking for three days is detrimental to humans, because in this case it is impossible to ensure the functioning of all organs and systems. Experts recommend treating some diseases with water, which proves the beneficial properties of this substance.

The presence of fluid in the human body

The human body consists of 60-75% water, which is distributed through tissues in certain quantities. Most of it is in the brain (85%) and blood (80%). Every cell of the human body is made of water, so dehydration has serious consequences: health deterioration up to the failure of individual organs. To prevent this from happening, you need to know exactly how much water you need to drink per day.

Particular attention should be paid to the watering of children. And also the drinking regimen during pregnancy is very important, because water is necessary for the normal development of the fetus. The embryo during the period of active growth consists of 90–97% liquid, so expectant mothers should ask the doctor how many glasses of water they need to drink per day.

Influence of water and its lack on the human body

Everyone knows that water is a necessity, the source of all living things. Getting into the human body every day, this liquid ensures the continuous work of all organs and systems, improves the appearance of the skin. Separate microelements in water have a number of important functions.

Impact of drinking water on health:

1. cleans blood vessels;
2. promotes the production of additional energy;
3. removes toxins;
4. improves the absorption of food;
5. helps to regulate body temperature;
6. reduces the likelihood of blood clots;
7. removes waste products;
8. takes part in providing cells with useful substances.

Lack of water in the human body causes a number of diseases and health problems. If fluid is not consumed every day in the required quantities, dehydration can develop - a stressful condition of the body, which will entail irreparable consequences.

In sick people, the need for fluid intake increases, especially in the presence of an elevated temperature. Therefore, any ailment should be treated taking into account a properly selected drinking regimen.

Dehydration can cause a number of problems:

• Increased blood clotting, thrombosis, which, in turn, provokes life-threatening diseases: varicose veins, stroke or heart attack;
• Disturbances in the work of the heart;
• Deterioration of metabolic processes, resulting in excess weight;
• Increased blood pressure;
• Formation of stones in the gallbladder;
• Disorders in the work of joints, the development of osteochondrosis;
• Deterioration of a person's appearance: skin, nails, hair;
• Diseases of the thyroid gland, kidneys, and other internal organs occur;
• The appearance of an unpleasant odor from the oral cavity;
• Frequent pain in the head and joints;
• Formation of stones in the bladder;
• Deterioration of the processes of food digestion, the occurrence of constipation.

It should be noted that only raw water purified with the help of special filters brings benefits to the body. Boiling kills both harmful and useful elements in it.

Drinking rate for an adult and a teenager

It is possible to establish how many liters of water a person needs to drink per day based on certain data: age, body weight and state of the body. It is believed that for 1 kg of weight it is necessary to consume up to 30 ml of clean drinking water per day. An increase in this rate causes an acceleration of metabolic processes, which has a beneficial effect on losing excess weight.

To determine the rate of drinking water, it is necessary to find out how much fluid the body loses during the day. If a person is overly active, then the amount of drinking should be sufficient to replenish the water balance. All vital processes are accompanied by the loss of fluid, starting with the functioning of individual organs and ending with breathing. On average, the daily consumption of water, which must be replenished by an adult or teenager, is 2–2.5 liters, or about 10 glasses.

Due to biochemical processes and food intake, it is possible to obtain only 30–40% of the liquid necessary for a person. In order to fully compensate for it, you need to drink water, without waiting for the onset of thirst. It is worth noting that tea, coffee and other sweet drinks in medicine belong to food, which means that only water is suitable for replenishing the water balance.

Thirst arises even when the body is sorely lacking in fluid, this is the first symptom of dehydration. Therefore, drink water in small sips throughout the day, without waiting for a signal from the body.

The required amount of liquid that a person needs to drink throughout the day is 1.5-2 liters. This applies to both adults and adolescents.

Factors affecting the increase in daily fluid intake:

1. Overweight, which requires at least 30 ml of drink per 1 kg of body weight;
2. Advanced age increases the need for water;
3. Treatment of various diseases with medicines, which requires the consumption of additional amounts of fluid;
4. Increase in ambient temperature;
5. Breast-feeding;
6. Decrease in air humidity;
7. Increased protein in the diet;
8. Active weight loss;
9. Drinking alcoholic beverages, coffee and smoking.
10. Additional water is used as a treatment for certain diseases.

Drinking rate for children

Children are in great need of proper drinking regime. In this case, increased attention should be paid to the quality of the liquid. The newborn should be given soft water, additionally boiled. It is enough for such a baby to drink 100-200 ml of liquid a day, the rest he gets from food.

If the baby's temperature rises, vomiting or diarrhea is observed, then his need for water increases significantly. In this case, you should consult a doctor who will prescribe treatment, as well as the daily drinking rate.

A child under the age of 7 should drink 1.2-1.7 liters of water per day. Moreover, it is better to boil it. If possible, sweet and carbonated drinks should be excluded, because they do not benefit the child, but rather the opposite: they cause problems with teeth and weight, as well as an increased feeling of thirst. It is better to give preference to mineral carbonated or still water. A child aged 7-12 needs to receive an additional 1.7-2 liters of fluid per day.

The value of water for a pregnant woman

Drinking water during pregnancy should be very careful, because in the later stages, excess fluid threatens with the appearance of edema, which complicates the process of carrying a child. At the same time, an adequate drinking regime helps to improve the well-being of a young mother.

Functions of water during pregnancy:

1. replenishment of the lack of fluid in the body of the mother and baby;
2. cleansing the body;
3. reduction of symptoms of toxicosis;
4. lowering blood pressure;
5. normalization of bowel function;
6. prevention of constipation.

In order to avoid the appearance of edema, pregnant women need to drink water with lemon. Lack of fluid during this period threatens the baby and affects the quality of amniotic fluid.

How to drink water properly

Some people drink the right amount of fluids randomly, without controlling the time and portions. But, in order to get the most out of water, you must adhere to the general recommendations for its use.

Rules for drinking water:

• The required amount of liquid should be drunk slowly, in small sips;
• After waking up, it is recommended to immediately drink a glass of water;
• Refrain from drinking 30 minutes before meals;
• After eating, you should not drink for 40 minutes;
• After training and strong physical exertion, you must drink a glass of liquid;
• You should not drink a lot of water at once, it is better to use it 8-10 times a day;
• The daily rate of water consumption affects how many times you need to drink: the more the rate, the more receptions;
• You need to drink water at room temperature, not too cold or hot;
• A person who drinks a glass of water 30 minutes before bedtime protects himself from a stroke at night.

Everyone can use these recommendations in practice and see how water affects health. The wrong drinking regimen significantly reduces the benefits of drinking it.

Drinking water as a therapy

There are diseases that can be treated with water. In some cases, the correct drinking regimen is much more effective than the use of honey preparations.

The use of water therapy is indicated in the treatment of:

• Asthma - an increased level of water in the body provokes a slowdown in the production of histamine, which provokes the development of the disease.
• Arthritis - the required amount of fluid in the body improves the condition of the joints, helps to get rid of the lack of water in the cartilage.
• Increased cholesterol - the intake of sufficient water in the body prevents the formation of sterol.
• Cold - in this case, the daily dose of water that the patient usually drinks must be increased by 10–20%. This promotes the rapid elimination of harmful toxins from the body.
• High blood pressure - This condition occurs with dehydration, so treatment includes increasing water intake. In the presence of heart failure, desoldering should be done very carefully, injecting liquid in small portions to prevent negative effects.
• Drinking regimen should be moderate for health problems such as urinary incontinence and kidney and heart disease.

Water is one of the main elements that ensure the vital activity of the human body. It is necessary daily for both the child and the adult in certain quantities. The correct drinking regime is very important for health, which means that you should not neglect a portion of clean drinking water or replace it with sugary carbonated drinks and juices.

AiF experts have analyzed the most popular of our misconceptions.

1 myth: you need to drink at least 8 glasses of water a day.

“A person really needs to consume 1.5-2 liters of liquid per day,” says Mikhail Zeigarnik, Executive Director of the National Society of Nutritionists... "But it is not necessary just water - 50% of the liquid must be obtained from various dishes, for example, soup, and 50% - tea, juices, milk."

Myth 2: swallowed gum blinds the intestines.

“Chewing gum does not dissolve in the stomach,” explains Alexey Severtsev, surgeon, professor... - The literature describes isolated cases when a child who swallowed several chewing gums developed intestinal obstruction. If the child has swallowed the gum, but the state of health does not deteriorate, then everything is in order. "

Myth 3: if a person eats well, but at the same time loses weight, it means that he has worms.

Myth 4: If you feel good with high blood pressure, then you do not need to drink pills.

“The risk of serious complications (stroke, heart attack, kidney damage, decreased vision) is equally high both in patients who experience high blood pressure (headaches, pain in the heart) and in those whose increased pressure is not accompanied by a deterioration in well-being,” explains Artyom Doletsky, Associate Professor of the Department of Preventive and Emergency Cardiology, P.M. I. M. Sechenova. -

5 myth: if you eat less, the stomach will decrease, the appetite will also decrease, and the person will lose weight.

In adults, the size of the stomach usually does not change. “A good and effective rule for losing weight is to eat more often and little by little,” says Mikhail Zeigarnik. "Then the appetite does not have time to form, and the person will not eat much."

6 myth: if a child grinds his teeth in a dream, he has worms.

“Research on this topic has been carried out several times,” says A. Bronstein, “but the connection between these factors has not been found. Teeth grinding in sleep (bruxism) occurs due to malocclusion, diseases of ENT organs or nervous disorders. "

Myth 7: an hour of sleep before 12 at night replaces two hours after midnight.

“This popular formula works for early risers,” says Roman Buzunov, MD, somnologist, member of the European Society for the Study of Sleep Disorders... - If the "owl" is forced to go to bed at 10 o'clock in the evening, she still will not fall asleep right away. And after 1-2 weeks of such torture, she may even develop insomnia. Therefore, another formulation is more correct: the first 3-4 hours of deep sleep are important for restoring the body's energy and producing the necessary hormones. And until 12 at night or after - it depends on a person's own biorhythms. "

Myth 8: a man is not designed for one woman, but for five.

“Nonsense! - objects Mikhail Koryakin, urologist-andrologist, doctor of medical sciences, chief physician of the Republican Center for Human Reproduction. - As well as the myth that a man is designed for a certain amount of ejaculation.

There is enough semen to satisfy even a thousand women, but a normal man doesn't need it. "

Myth 9: kefirs and yoghurts with live bacteria are healthier.

“To get into the intestines, bacteria need to go a very long way, fraught with the influence of aggressive factors: hydrochloric acid in the stomach, the digestive enzymes of the duodenum, so they hardly come to the goal alive,” says Igor Khalif, Professor, Head of the Department of the State Scientific Center of Colo-Proctology... - So any fermented milk products are useful, not only with bacteria - they help your own good flora to grow. "

Myth 10: If you quit smoking, you will definitely get better.

"Optional," objected Vladimir Levshin, Professor, Head of the Department of Tumor Prevention, Russian Cancer Research Center. N.N.Blokhina RAMS... - Someone's weight does not change, some of the former smokers recover by 2-4 kg. And only 3-4% of those who quit smoking gain 9 kg or more in weight. The reason is that the gastric mucosa is restored, and nutrients and vitamins are better absorbed. "

The body consists of 60% water, which we consume and excrete. We are constantly losing water, primarily in urine and sweat. There are many different opinions about how much water to drink per day.

Health professionals generally recommend drinking about 2 liters daily. However, there is another opinion, according to which it is believed that the human body is always on the verge of dehydration, and that we should drink water constantly, even when we don't want to.

As with most things, it all depends on the individual, and there are many factors (both internal and external) that affect how much water you should drink per day. Let's take a look at some studies that look at water intake and its effect on body and brain function, and then try to figure out how to customize water intake to suit individual needs.

Can drinking water really boost energy and brain function?

Many argue that if a person suffers from dehydration, then he gets tired faster and his brain functions suffer. There are many studies that support this.

In one study, women lost 1.36% of their fluid during exercise, and their mood and concentration worsened and the frequency of headaches increased.

There are other studies showing that mild dehydration (1-3% of body weight) caused by exercise or overheating can adversely affect many other brain functions.

However, keep in mind that 1% of your body weight is a significant amount. Such a large loss of fluid is possible especially when you sweat a lot, for example, during exercise or in high ambient temperatures. Moderate dehydration can also negatively affect physical performance, leading to decreased endurance.

Takeaway: Moderate dehydration caused by exercise or overheating can have negative physical and mental health consequences.

Will drinking plenty of water really help you lose weight?

Many people believe that the amount of water consumed has an effect on body weight: if you drink a lot of it, the metabolism accelerates, and the appetite decreases.

According to two studies, drinking 500 ml of water at one time can temporarily increase metabolism by 24-30%. The top line on the graph shows how metabolism (ER, energy expenditure) increases after drinking 500 ml of water. By the 90th minute, this effect decreases.

Researchers have calculated that drinking 2 liters of water daily increases energy expenditure by about 96 calories per day. To do this, it is better to drink cold water, because in this case the body will expend energy (calories) to heat the liquid to body temperature. By drinking water half an hour before meals, you can reduce the amount of calories you consume during meals, especially in the elderly.

One study found that eating a diet that requires you to drink 500 ml of water before meals can lose 44% more weight in 12 weeks than following a regular diet. In general, drinking enough water (especially before meals) has a positive effect on the process of losing weight, especially when combined with a healthy diet.

So you can use all sorts of supplements for fat burning, for example, find out to speed up the process of losing weight.

Conclusions: water can cause a slight temporary boost in metabolism, and drinking water half an hour before meals can lead to a decrease in the number of calories consumed.

Does drinking more water help prevent disease?

There are several health problems that can be resolved with increased water intake:

• Constipation: Increasing your water intake will help cope with a common problem, constipation.
• Cancer: There is some research showing that those who drink more water have a lower risk of developing cancer of the bladder and rectum (although there are other studies that do not see this effect).
• Kidney stones: Increasing water intake can reduce the risk of kidney stones.
• Acne and Skin Hydration: There are many occasional reports on the internet that water can help moisturize the skin and reduce acne, but there are no actual studies to confirm or disprove this.

Bottom Line: Drinking plenty of water can help fight health problems such as constipation and kidney stones.

Do other liquids count towards the total water volume?

Plain water isn't the only thing that affects fluid balance, other drinks and foods are also important.

It is believed that drinks containing caffeine (such as coffee or tea) should not be counted in the daily amount of water consumed because caffeine is a diuretic. However, studies show that this is not the case because the diuretic effect of these drinks is very weak. Most foods also contain water. Meat, fish, eggs, and water-rich fruits and vegetables contain significant amounts of water. If you drink coffee or tea and eat water-rich foods, then most likely this is enough to maintain fluid balance (unless you sweat very much, of course).

Bottom Line: Other drinks can also help maintain fluid balance, including caffeinated drinks like coffee and tea. Most foods also contain water.

Obey your thirst - it won't cheat

Keeping hydrated is very important to our survival. For this reason, evolution has given us an intricate mechanism for regulating when and how much we should drink. When the total body water content falls below a certain level, thirst appears. This control is analogous to the breathing process: we do not have to consciously think about it.

Most people don't need to worry about drinking water. The instinct for thirst is a very reliable mechanism, and it has helped us humans survive for a very long time. In this case, you do not need to adhere to any rules. This is arbitrary.

There are circumstances in which more water may be required than usual. Most important is the increased sweating that occurs during physical work or exercise, and in hot weather (especially in dry climates). If you sweat a lot, you should drink enough water to replenish your fluid losses. Athletes who do prolonged intense exercise also require electrolyte replenishment.

The need for water increases during breastfeeding, as well as in certain painful conditions such as vomiting and diarrhea. Older adults should be conscious of their water intake because some studies show that thirst regulation mechanisms may not work properly in old age.

Conclusions: Most people should not think about drinking water because the mechanism of thirst in the brain works very effectively. However, certain circumstances require increased fluid intake.

How much water should you drink?

No one can say exactly how much water you need to drink per day. It all depends on the individual. Experiment with yourself. For some people, performance increases against the background of increased water intake, while for others it only causes inconvenience due to more frequent trips to the toilet.

What is the water norm? The norm is 30-40 ml of water per 1 kg of weight. If you need the usual norm of an average person, then we take 30 ml, if you have an extra couple of kg, then you can take 40 ml per 1 kg of weight.

For example, if you weigh 53 kg, then your water norm is 1.6 liters per day.

If it is summer time (it will come soon), then add 500-700 ml to the norm, in winter I also advise increasing the norm (heating, which dries the air, fur coats, heaters - all this dries us up).

If you go to the gym, swimming pool, and no matter what you do (even if you do cycling), your norm is also + 500-700 ml of water.

What is water?

Water is pure water. BUT not carbonated water and drinks, not tea, not coffee, not fresh juices, not compotes are not counted as clean water.

There are recommendations to include in the diet instead of black tea and coffee (which are dehydrating drinks), add weakly brewed green tea (that is, not strong), and you can also drink herbal teas (linden, mint, lemon balm).

In the morning, it is recommended to add a slice of lemon to a glass of water to restore the acid-base balance in the body. Despite its sour taste, lemon water perfectly alkalizes and helps cleanse the body of excess acids.

Water with lemon is easier to drink in the morning, improves digestion, helps cleanse the intestines, removes fats, helps to lower blood pressure, energizes and invigorates for the next day.

How to choose water?

Be guided by taste first of all - you like this taste of water, it is easy for you to drink it, will you be able to drink your norm during the day?

You can choose either filtered (by special systems, I prefer coal from jugs), bottled (both purchased in stores and for children in pharmacies and other places), water from a source may be the most delicious of course (but not in all cities such sources are easy find, but you can search over time in order to save, at least). The main thing in this is to go deep in the first days. If there is a filter at home, then we drink from the filter, if we bought bottled before, we drink it, if the taste is still not pleasant, then try to buy a nursery (at first I drank only this). Boiled water can only be used to slightly dilute the water to room temperature (again, then water is easier to drink).

How to drink water throughout the day?

The most important thing is to get the day right. The morning begins with a glass of water (warm, room temperature), you can drink it without getting out of bed (in the evening prepare a glass near the bed). And a second glass to drink after the morning toilet.

Then proceed according to the scheme, every hour you need to drink a glass of water, you can use a reminder for yourself on your phone: For iOS - WaterBalance, for Android - Water Your Body, Hydro Coach and Drink Water Reminder. It is advisable to complete the main drinking regime before 16-17: 00 (before this time, drink 1.5-2 liters), and the last glass of water 3-4 hours before bedtime (so that there is no discomfort in the morning - swelling, at night - going to the toilet, and even at this time, water is no longer as needed as in the daytime).

So this is what the circuit looks like:

In the morning 1-2 tbsp 250 ml each

Every hour 1st - it can be stretched for an hour, not in one gulp to drink a glass, but in sips a little.

Before meals 1 tbsp - 30 minutes (you can half a glass and before the very reception).

After eating 1 tbsp - depending on the food and your well-being (you can do it right away, you can do it in an hour so that there are no heavy sensations), general recommendations an hour after eating

The last glass of water 3-4 hours before bedtime (if you really want, you can take a couple of sips just before bedtime).
