Proven by science: how much water you really need to drink. How much water to drink per day: tips and myths How much water to consume per day

How much water do we need to drink to lose weight, be healthy, energetic and young?

And how to drink water correctly in order to maximize the effect of drinking water and improve your health? Not many people know these simple six rules, but they really work!

What are the three foundations of our life without which we cannot exist? There are only three of them: food, sleep and water. And if we constantly remember the importance of the first two and try to regulate them, then many people forget about the last factor or simply ignore it ...

Why do we need to drink water?

Each of us has heard that we are 75% water - this is already a rather hackneyed phrase))) But not everyone knows that by the end of life our body is already about 50% water. Wow! Truth?

We need a lot of water so that our body can function properly and we feel good.

We need water for blood health, brain health, heart health and just every part of our being. We need water both inside and outside of our every cell to dissolve nutrients, carry waste, regulate body temperature, send brain messages, and lubricate all of our moving parts.

Girls, attention!!! We also need water for weight loss!

How water helps you lose weight

Without water, easy and proper weight loss will not work, because it is involved in all the processes responsible for losing weight. Water:

Removes all toxins and toxins (preventing us from losing weight)
Actively involved in the breakdown of fats (4 molecules of water are needed to break down one molecule of fat, so if there is not enough water, then weight loss slows down)
Speeds up our metabolism (up to 30% by the way)
Allows us not to overeat - in our brain, the center of hunger and thirst are located very close, and sometimes we just want to drink, but take it for a desire to snack and lean on extra and unnecessary calories
Moreover, it increases the elasticity of the skin, which suffers greatly from improper weight loss.
However, we naturally lose a lot of water every day through breathing, sweat (even when not exercising), urine and bowel movements. But over time, we ourselves dehydrate our body even more, replacing water with fruit juices, various drinks, and even simply drinking lower quality water.

How do we know that our body needs more water? Here are five simple signs that it's time to start drinking more water.

Signs that you need to drink more water

1. Inflammation - if you often get clogged skin pores, which leads to acne and pimples, skin rashes, or sometimes red eyes
2. Dryness - if you notice that your hair, skin, eyes, lips become dry

3. Urine color - if after the night your urine is dark yellow (not light yellow)
4. Constipation - if it happens that you do not go to the toilet “in a big way” for more than a day
5. Sweat - if you rarely sweat (or don't sweat at all)

If you notice that you are experiencing these signs, it means that it is time to think about replenishing your body and drinking water a little (or a lot - it all depends on your degree of dehydration) more.

So, how much water should you drink to ensure your body functions properly and healthy?

How much water to drink

We all know that we need to drink water, lots of water, every day…etc. etc…. Everyone talks about it, but not everyone knows exactly how much you need to drink a LOT.

So how much water is included in this voluminous concept: a lot?

In order not to be mistaken, there is a simple and proven formula: 30-40 ml of water per 1 kg of weight. That is, if I weigh 60 kg, then I should drink at least: 30 x 60 = 1800 ml of water. And this is the minimum!

Of course, there is a reasonable limit in everything, and if a person weighs 100 kg, he will not be able to drink even three liters (not to mention four). Therefore, nutritionists advise in any case to drink no more than 2.5 liters. Otherwise, there is too much stress on the kidneys, and instead of benefit, we harm our body ...

And pay attention: it is water that is considered water, and not any liquid like juice, soup, coffee, etc., since these drinks are considered food.

And now about how to drink water correctly.

How to drink water correctly

Many drink in the following way: I remembered in the middle of the day that I hadn’t drunk anything yet - and ran to the tap to drink two glasses at once (because otherwise you won’t have time to complete the entire daily norm). But… Not so!

Once upon a time, I didn’t know these rules either, and each of my attempts to “drink more” ended up running to the toilet endlessly (sorry for the details, but this is important). In a healthy person, it is considered normal to urinate once every three hours. When we drink a lot of water, but WRONG, we go to the toilet after almost every portion of water we drink (and the urine is clear at the same time). And it shouldn't be like that! This indicates that we are drinking incorrectly, and the water is not completely absorbed, but simply immediately excreted from the body (giving an additional and unnecessary burden to the kidneys).

Thanks to Ayurveda, I learned to drink water CORRECTLY: so that it is completely absorbed by my body and nourishes it with vital energy.

You need to drink water according to certain rules. Just six simple rules

Rules for the correct use of water

1. Drink water only OUTSIDE of meals (no later than 40 minutes before meals and no earlier than 1.5 hours after meals) - so that water does not dissolve gastric juice and interfere with agni (in Ayurveda, agni is a biological fire responsible for digestion and assimilation of food, as well as for metabolism, and hence for weight loss).

2. Drink warm water instead of cold water - ice water freezes the enzymes in the intestines, preventing it from properly digesting food. Moreover, cold water constricts blood vessels, which prevents the outflow of lymph and interferes with blood circulation - which means our organs do not receive the necessary nutrients. This rule is very important for women on critical days and for those who want to get pregnant.

3. Drink water in small portions (2-3 sips) so as not to burden the kidneys. After all, if you drink a glass of water in one gulp, it will not have time to fully assimilate and is almost completely excreted from the body (by setting unnecessary work for the excretory system). But if you drink in small sips, then this water will purify the blood and ensure the regeneration of body cells.

4. After each sip, hold the water in your mouth so that it mixes with saliva and is better absorbed.

5. Drink a glass of warm water immediately after waking up - do not wait 10-20 minutes, but immediately, as soon as you get out of bed and complete your morning routine for a vigorous day)). It kind of flushes the body and starts the work of the intestines (and rids the body of accumulated toxins). Perhaps not all of this water will be absorbed, but this amount of water will stimulate the intestines - this is the only time when it is recommended to drink a large amount of water at once (see point 3). For a greater cleaning effect, you can drink a special detox drink, which helps not only to cleanse yourself of toxins and toxins, but also to lose weight.

6. Drink water only while sitting (not standing!!!) - so it will be completely absorbed into the blood in the intestines, otherwise it will simply come out (((

If you follow these simple rules, then in a month you will notice that the skin and lips have become less dry, the hair has become alive and shiny. Magical and life-giving changes are taking place inside your body. And most importantly - there is a lot of energy, and you no longer feel tired. After all, water is life!

Well, what do you say - do you drink correctly? Or differently?

Water is a source of energy and strength. How much water should you drink a day to lose weight? What are the benefits of water to the body? And what should you pay special attention to when using it. All this, read below.

The benefits of water cannot be overestimated. On average, each person should consume 1.5-2 liters daily. To accurately calculate how much water you need to drink per day, use the following formula:

  • For men: 35 x body weight
  • For women: 31 x body weight

For example, if you are a girl and your weight is 60 kg, then your water intake per day is (60 x 31) = 1860 ml. On the day of training, the figure should be increased by at least 500 ml. The benefits of water during sports are obvious: it helps to restore the body after physical exertion, and also promotes the supply of amino acids to muscle cells and the absorption of proteins.

How much water should you drink per day?

Probably everyone has heard about the huge benefits of drinking water. Let's take a closer look at the beneficial properties of water and its effect on the body.

10 facts about the benefits of water

  1. Water is a nutrient medium for cells; with its help, all chemical processes in our body proceed. Blood contains 90% water, brain - 85%, muscles - 75%, bones - 28%.
  2. Water plays a vital role in the weight loss process. If it is not enough in the body, then the kidneys cannot function normally. And then the liver comes to their aid, which means that its ability to participate in the metabolism of fats is sharply reduced.
  3. With insufficient water intake, the skin, intestines and joints suffer. It is from them that our body takes fluid for the normal functioning of such important organs as the liver, brain, heart and lungs.
  4. Sometimes we mistake the brain signal for dehydration for hunger. If you feel like snacking, drink a glass of water - you are almost guaranteed to satisfy your hunger.
  5. Another benefit of water: it is rich in mineral salts. Its composition will differ depending on the region and the breeds through which it passes. Some have more, others have sodium and.
  6. Due to insufficient water intake, many diseases develop, because the body cannot resist dehydration on its own. It will begin to take water from the cellular and extracellular fluid, and then from the bloodstream.
  7. Water contains 0 calories, so you can drink it without worrying about your figure.
  8. A dehydrated body cannot cleanse the organs of harmful substances in a timely manner, and they enter the bloodstream. This instantly affects the condition of the skin, which becomes dry and flabby, begins to peel off, acne appears on it. By the way, if you care about your health and beauty, then do not forget to monitor oral hygiene. Quality services for the prevention and treatment of dental diseases are offered here: http://stomatologis.ru/
  9. Water is a kind of vehicle for the delivery of vitamins and enzymes to all cells of the human body.
  10. It also contributes to the normal functioning of the intestines. Regular lack of fluid can provoke constipation and digestive disorders.

How to make yourself drink water?

When a person feels thirsty, this is already a serious bell from the body, signaling his dehydration. Don't let him get to that point. But how do you force yourself to drink water throughout the day? We recommend that you follow some simple tips:

  1. Start your day with one glass of water. If you like to lie in bed in the morning, put a bottle of water next to your bedside table and drink it immediately after waking up.
  2. Always bring a 1.5 liter bottle of water to work or school. Keep it always with you, and you will not notice how you empty the container sip by sip.
  3. If you forget about regular fluid intake, download a mobile application on your phone that will promptly remind you how much water you need to drink per day. For example, Water Balance or Water Your Body.
  4. In the evening, a glass of water saves you from extra portions for dinner. If you want to save yourself from eating at night, quench your thirst in a timely manner. But it is not recommended to drink water right before going to bed: it can overload the kidneys and cause swelling.
  5. To improve the taste of water, add a few drops of lemon juice to it.

In a week you will not force yourself to drink water - your body will get used to it and will remind you of the need for it.

However, everything must be done wisely. Do not exceed the prescribed rate of water, because its excessive use can also be harmful, namely, put a strain on the kidneys and heart.

Rules for drinking water:

  • Do not drink water with meals: it makes it difficult to digest food. Also, you should not drink it less than 20 minutes before a meal and within 45 minutes after.
  • On the day of training, increase the rate of water consumption by 0.5-1 liter and do not forget to drink it before, during and after class.
  • Consume pure water. Tea, coffee, lemonade, juice do not count!
  • Coffee takes moisture out of the body. For 1 cup of coffee, there should be 2 cups of water to restore water balance.
  • The ideal temperature of drinking water is 20°C. This will help increase the calorie expenditure that is spent on warming the body. However, do not abuse it, too cold water can provoke a sore throat.
  • It is undesirable to use tap water: it contains bleach and other harmful impurities.

Everyone is well aware of the information that a person is 60-80% water. Everyone knows that if a person can survive up to 60 days without food, then only 3 days without water. That is, it is obvious that it is necessary to drink water every day in sufficient quantities. But how to determine this rate? Let's try to figure out how many liters of water you need to drink per day in order to maintain good health. And at the same time we will find out what water to drink, when to drink and how to do it correctly.

You can easily find answers to all these questions in our article!

Water is life!
First, let's remember why our body needs water:

  1. water transports nutrients to cells
  2. water, being a universal solvent, dissolves various substances that enter the body
  3. slags and toxins are removed with water
  4. water regulates the body's heat exchange processes
  5. without water, the muscular system will not be able to function normally, the joints will not be able to work properly
  6. up to 90% of the human brain is water
  7. and this is not the whole list!

How much water should you drink?
Once again making sure from the above facts that water is life, we are approaching the next point: how much water should a person drink per day.

Everything is ambiguous here, if you want to immediately get the desired answer, then scroll through this paragraph of the article to the last paragraph. And for those who want to deal with this issue in detail, I have prepared the most detailed information from a variety of official sources. All of them give very divergent data on the required daily minimum of water: some say that it is 1.5 liters, others that it is 2 liters, and still others that it is at least 3 liters ...

Few people try to understand the issue thoroughly and in detail, and this is dangerous! And very dangerous, when the person who typed the query " » sees in the first place the result of quick issuance in the form of a picture of something like this:

I specifically made a note this is bad advice!!!' because that's the way it is. Many people, having seen such a result, blindly begin to follow it, endangering their health. Moreover, this recommendation is just one of many proposed by a variety of scientific institutions.

I draw your attention to the fact that all possible ways of calculating the rate of water consumed are only recommendations, and not a rigidly fixed value, and it changes under various circumstances up or down. For example, during active physical work, or just on a hot day, or during illness, the body's water consumption increases significantly, and the daily rate increases accordingly. In general, it must be remembered that in the calculations all water entering the body is taken into account, that is, not only in its pure form, but also in the form of food. Thus, if you ate a couple of impressive bowls of liquid soup during the day, drank more than one glass of juice, ate several juicy fruits, then the need for plain water will be less than the calculated norm.

METHOD 1. The most common opinion on this issue is the official recommendation of the World Health Organization (WHO): For one kilogram of weight you need 30 milliliters of water per day. That is, for example, with my weight of 70 kg. (70×30=2100) I need 2.1 liters.

METHOD 2. One of the simplest tips that can be found on the issue of the required amount of water is to drink about one liter of water for every thousand calories eaten. Maybe it’s not bad, but honestly, how long will you last with the calculation of the calorie content of the food you eat? I know for sure that I will “loose” very quickly and simply “forget” this tedious task!

METHOD 3. An option for those who do not want to bother with any calculations, but very very close! Employees from the American Institute of Medicine have compiled an approximate recommended amount of water needed depending on gender and age group. For convenience, see the data in the table ( increases on click):

METHOD 4. Let's find out what domestic science says about the water norm. The Russian Institute of Medicine is not very specific in its recommendations, its specialists measure water in glasses and say that a man needs 12.5, and a woman 11. If we are talking about standard glasses, then it turns out male norm 12.5 cups * 250 ml = 3125 milliliters; respectively, the norm of water for women 11 glasses * 250 ml = 2750 milliliters. Agree that this is a very generalized and simplified way, I think it does not suit us.

METHOD 5. There is another formula recommended for calculation by English experts. I'll tell you right away what applies here. not metric, so you will additionally have to use the converter in your smartphone or any online converter. So the formula is: Divide your weight by 2.2, then multiply by your age, then divide by 28.3. I’ll try to calculate my water rate per day, for this, in the online converter, first I select “Weight, mass” in the list and translate my “kilograms (kg)" into" English pounds"( = 154.324 pounds). Divide pounds by two point two tenths, multiply by 38 years, then divide by 28.3, and you get 94.190 ounces of water. Now in the converter I choose " Volume, capacity"And translate the result from" ounce (UK)” to “liter (l)”. The result is my daily allowance for this formula is 2.676 liters of water. This is half a liter more than the WHO recommendation, which, in principle, is a comparable value.

METHOD 6. Well, a very simple approach is offered by Harvard researchers: they are convinced that in order to maintain a normal water-salt balance in the body, it is enough for a person to drink a day 4–6 glasses water. If we take into account that in the USA ( and Harvard University is located there) when we talk about a glass or a cup of water, we mean a volume of about 237 - 240 milliliters, then we get the recommended by local scientists daily dose of 960 - 1440 milliliters. That is, much less than the notorious 2 liters!

So, as you have seen, the scientific world simply does not have a common opinion on the issue of interest to us, but you can still derive some average indicator for yourself.

METHOD 7. And finally, in this paragraph of our " wet case investigations", I saved the latest recommendations of scientists: it turns out that the latest research says that the rate of water drunk per day is a purely individual parameter, for the exact determination of which it is necessary to take tests and conduct special laboratory tests! That's it... ( here the music from "Jumble" suggests itself - couple-pair-pam! ). I think that it is worth listening to sensible doctors who say that the daily water intake is different for different people. In my opinion, this is logical and obvious, well, you must admit that 1.5 liters per day for a fragile girl weighing 40 kilograms can be even more than enough, and this amount is not enough for a 90 kilogram man. It is clear that the opportunity to conduct appropriate laboratory studies is only in large cities with serious scientific centers, so most people only have to carefully listen to the signals of the body in order to notice the lack of water in time and promptly replenish it. So we come to the next point - when should you drink water?

When should you drink water?
You need to drink water wisely, as a rule, the body itself will tell you that it does not have enough fluid. The most obvious signal is a feeling of thirst, even if you are only slightly thirsty, in no case should you ignore this signal, be sure to drink. Especially a lot of clean water is necessary when you stay in hot air for a long time, otherwise you can get a heat or sunstroke with severe consequences.

If in principle you never experience a feeling of thirst, this should alert you, since it does not mean at all that the body does not need fluid. Doctors warn: lack of desire to drink water, especially when it objectively should be (exercise, heat, etc.) - this is not your unique feature, but health problems are very likely, for example, weakening of kidney function or a failure in the passage of impulses in nerve cells!

Remember that the feeling of thirst is only one of the signs of a lack of water in the body, the rest are not so obvious and you will need to carefully listen to the body to detect them. Non-obvious signals of a violation of the water balance may be such signs:

  • 1) sudden unexplained fatigue
  • 2) great absent-mindedness and loss of concentration
  • 3) dry and wrinkled skin
  • 4) fragility of nails and hair
  • 5) prolonged depression and stress not associated with the influence of external conditions
  • 6) pain or discomfort in the joints
  • 7) frequent constipation
  • 8) dark color of morning urine and its pungent odor
  • 9) acne, plaque on the tongue
  • 10) with a lack of water, the blood “thickens” and the heart needs more effort to pump it, as a result of which a rapid heartbeat is observed.

Important! What water to drink and how to do it right.
It is worth remembering that it is necessary to drink unboiled pure(filtered) not cold water. By the way, Japanese scientists recommend drinking warm water on an empty stomach ( how much - they did not specify, probably no more than a mug or glass ...), its temperature should be one degree higher than normal body temperature ( it turns out 37.6 degrees?). Thus, scientists assure, water has a beneficial effect on the state of the body, helps to lose weight and maintain a slender figure. The same conclusions were reached by employees from the Virginia Tech University, who advise those who want to lose weight to drink two glasses of water before each meal ( so-called " water diet", which in no case not to be confused with a rigid "water diet", in which almost complete refusal of food and the use of only water is practiced - such an option officially recognized as the most unhealthy diet!) ).

More = better?
As for the prevailing opinion about the benefits of increased water consumption compared to the recommended norm, the issue here is very controversial.

If you search for information on this topic, then approximately 50% of media reports say that "a group of scientists conducted studies that proved the positive impact of a few extra glasses of water a day on human health", and the other half of the messages claim that “no relationship has been found between increased water intake and improved health…”.

It is important to remember such dangers as " drinking sickness"! This is when a person consumes much more water than his body can absorb ( and in a healthy person, the kidneys can process a maximum of 1 liter in one hour, but as a rule, this amount is even less, about 800 milliliters) resulting in excessive sweating, swelling, increased pressure, heart failure, and the worst possible option is swelling of brain cells ( edema), which can be fatal. (but fortunately, such a sad outcome is extremely unlikely).

Who to believe is completely unclear, so it remains only to verify empirically. Probably, the individual characteristics of the body are critically important here, perhaps a couple of extra glasses of clean water a day will be beneficial for you, but your friend will not be of any use. Try, listen to the signals of the body and draw conclusions individually for yourself.

How much water should you drink per day?

You have probably heard that you should drink 8 glasses of water a day. In fact, the amount of water is chosen more individually than you think. Now scientists recommend that men drink about 2.9 liters of water per day, that is, about 12 glasses. They point out that women only need 2 liters, which is about 8 glasses. Even now, the answer to this question is not so simple.

The 8-glass rule is a good start in answering the question of how much water to drink. But there is no accurate, well-studied information to support the correctness of this method. Your body is 60% water. All organs in your body need water to function. Your recommended water intake is based on many factors, including your gender, age, activity level, and others such as pregnancy or breastfeeding.

We have downloaded recommendations for various groups of people, systematizing them into a table of the approximate amount of water depending on age and gender. And then the aspects of the positive impact of sufficient fluid intake for your body (supported by specific scientific studies) and tips for real life are considered.

Scientists now recommend that people aged 19 and over drink 3.7 liters of water for men and 2.7 liters for women. This is your total fluid intake per day, including everything you eat or drink, such as fruits or vegetables.

From this it follows that men should drink about 12 glasses of drinks, and women - 8 glasses (hereinafter, we mean glasses of 250 grams).

Recommendations for children are highly dependent on age. Girls and boys from 4 to 8 years old should drink about 1.1 liters per day, that is, 4-5 glasses. The amount will increase to 1.6 - 1.8 liters (approximately 6 - 8 glasses) from 9 to 13 years. For 14-18 years old, the recommended amount of water is 1.8 - 2.5 liters (that is, 7 - 10 glasses).


Women of reproductive age

These are approximate norms for average people. Naturally, the more a person weighs, the more water his body needs during the day. On average, we can assume that For every kilogram of body weight, you need 30 milliliters of water per day., and when playing sports - 40 milliliters [in some sources you can find calculations based on about 28 milliliters per 1 kilogram per day, in others - 33 milliliters per kilogram, but these are numbers of the same order]. That is, with a body weight of 80 kg, you need to drink about 2.4 liters of water (and when playing sports - 3.2 liters) of liquid. At 70 kilograms - respectively, you need to drink water about 2.1 or 2.8 liters.

Other aspects

You need to drink more water if you live in a hot climate, exercise often, or if you have a fever, diarrhea, or vomiting.

● Drink 1.5 - 2.5 more glasses if you are exercising. Most likely, you need to add more if the workout lasts more than 1 hour.

● Drink more water if you live in a hot climate.

● If you live at an altitude of more than 2500 meters above sea level, you need to drink more.

● When you have a fever, vomiting or diarrhea, your body loses more fluid than usual, so you need to drink more. Your doctor may advise you to drink electrolyte drinks to maintain a stable electrolyte balance.


Why do we need water?

Water is essential for most processes in your body. When you drink water, you replenish your reserves. Without enough water, your body and its organs will not be able to function properly.

Benefits of drinking water:

● maintain body temperature within the normal range,

● lubricate and soften your joints,

● protect your spine and other tissues,

● Help eliminate waste through urine, sweat and feces.

Drinking water can also help you look your best. For example, water keeps your skin looking healthy. Skin is the largest organ in your body. When you drink plenty of water, you keep it healthy and hydrated. And also water contains 0 calories, so it is a great tool for weight management.

Increases energy and improves brain function

A lot of people say that if they don't drink during the day, their energy starts to drop and their brain starts to work worse.

There are many studies confirming this (studies are not mythical, links to 20 specific studies are given below in the text of the article).

One study in women showed that a 1.36% fluid loss after exercise impairs mood and attention, and causes headaches (see Study 1).

There have been many more studies that have shown that mild dehydration (1-3% of body weight) due to exercise or heat can have a negative impact on many aspects of brain function (studies 2, 3, 4).

Keep in mind that even 1% of body weight is actually quite a significant loss. This happens mostly when you sweat a lot during exercise or heat.

Mild dehydration can also have a negative impact on physical performance, resulting in reduced endurance (studies 5, 6, 7).

Helps to lose weight

There are many claims that drinking water helps you lose weight by boosting your metabolism and reducing your appetite.

According to two studies, drinking 500 grams of water temporarily improves metabolism by 24-30% (see source 8).

According to researchers, drinking 2 liters of water daily can increase energy expenditure per day by 96 calories (for more, see: with the calculation of the consumption rate).

In addition, it is better to drink cold water when you lose weight, because then your body will have to expend energy (calories) on heating the water due to body temperature. But this is a clear recommendation. For example, in the morning it is better to drink water that is slightly warm (about the same temperature as the human body).

Drinking water half an hour before meals can help reduce your calorie intake, especially in older adults (studies 9, 10).

One study showed that weight loss people who drank 500 ml of water before meals lost 44% more weight in 12 weeks than those who did not drink (study 11).

It is very important that you drink enough water, because this can prevent weight gain or obesity.

A recent study conducted in schools proved that water consumption reduces the risk of obesity in children. They installed water fountains in 17 schools and taught about the benefits of water.

At the end of one school year, the risk of obesity decreased by 31% percent in schools where water consumption increased (study 21).

Overall, it's safe to say that drinking enough water (especially just before a meal) can have a significant weight loss benefit, especially when combined with a healthy diet.

We emphasize that we are talking about a sufficient amount of water. The myth that you need to drink more water in order to sweat more during exercise and lose more fat remains a myth and has nothing to do with reality. Therefore, the question of whether to lose weight is inherent only to beginners. You need to drink an amount sufficient for the normal functioning of the body, and not overpriced specifically supposedly for the sake of losing weight.

Helps to avoid health problems

There are several health problems that increasing water intake can prevent:

● Constipation: Increasing water intake may help with constipation, which is a fairly common problem (studies 12 , 13 , 14 ).

● Cancer: There are several studies that have shown that increasing water intake reduces the risk of bladder and colon cancer, but some studies have found no effect (eg studies 15 , 16 , 17 , 18 ).

● Kidney stones: Increasing water intake reduces the risk of kidney stones (studies 19 , 20 ).

Pimples and dry skin: While there are no exact studies that would definitely confirm or deny this, but there is a common belief that water helps to moisturize the skin and prevent acne.

Risks of insufficient or excess water consumption


Dehydration

Your body constantly loses fluid during sweating and urination. Dehydration occurs when your body loses more water than it receives.

Dehydration has symptoms ranging from extreme thirst to feelings of exhaustion. You may also notice that you don't go to the bathroom as often, or your urine becomes darker. In children, dehydration can cause dry mouth or dry tongue, lack of tears when crying, and diapers that are less wet than usual.

Dehydration can lead to:

1) clouding of consciousness or unclear thinking,

2) mood changes,

3) overheating,

4) constipation,

5) the formation of kidney stones,

Mild dehydration can be treated by drinking water or other fluids. If you are severely dehydrated, you may need to be treated in a hospital. Your doctor will likely give you IV fluids and salts until your symptoms go away.

Hyponatremia

Too much water can also be hazardous to health. When you drink too much water, the extra water can begin to dilute the electrolytes in your blood. Your sodium level will drop and this can lead to a condition called Hyponatremia.

Symptoms:

clouding of consciousness,

Headache,

Fatigue,

Nausea, vomiting,

Irritability,

Spasms, convulsions, weakness,

Convulsive (epileptic) seizures,

Coma (unconscious state).

Getting hyponatremia due to water is uncommon. People with small bodies and children have a higher risk of developing this condition. Also active people like marathon runners who drink huge amounts of water in a small amount of time. If you might be at risk from drinking a lot of water while exercising, then try drinking sports drinks that contain baking soda and other electrolytes to help replenish the electrolytes you've lost during sweating.

Tips for Drinking Enough Water

You can drink enough water throughout the day if you drink every time you are thirsty and at meals.

Of course, advice like "Whenever you feel thirsty, drink" helps in most cases. But, if you exercise a lot, work hard physically, are in the heat or breastfeed, then you need to anticipate thirst: every time you just remembered the water (even without feeling thirsty) - drink some water (after all, if you waited until the moment when you already felt thirsty, it means that you have already "got into debt" to your body a little, without supplying it with water in a timely manner ).

If you need more help, you can use the following tips:

● Try to take a bottle of water with you wherever you go, including work, the gym, and even when you travel.

● Concentrate on the total amount of liquid, and specifically clean water. You don't need to drink the same amount of clean water that you need to stay hydrated. There are other excellent sources of fluids such as milk, fruit juices, tea and broth.

● Do not drink sugary drinks. Although you can get all your fluids from sodas, juices, or alcohol, these drinks contain a huge amount of calories. It is always best to opt for plain water.

● It is better to drink water half an hour before meals. But you can also drink while eating (not very much so that the digested food is flooded with gastric juice, and not water). It's better to have a glass of water than to order another drink. This way you can save some money and reduce the number of calories per meal.

● If you exercise hard, try sports drinks. They contain electrolytes that will help you replace those you lose when you sweat.

● Start the morning with a glass or 0.5 liter of water to start the body's metabolism after sleep (it is desirable that the water is a little warm, ideally - 36.6 degrees, as well as normal body temperature).
