"Water is the source of everything in the universe." Thus claimed Heraclides. And with this it is almost impossible to argue. Recollect, what first of all scientists investigate when it comes to finding "brothers by reason"? That's right, the presence of water on the planets. Because if it is - in any - solid, gaseous or liquid state - means, different forms of life are possible. Perhaps, everyone, even from the school program, knows that 2/3 of the surface of our planet is covered with water. Water, in more or less quantity, contains everything that surrounds us - even volcanic magma and stones. What can I say about people! The importance of water in human life is difficult to overestimate. No wonder still Dubois gave a precise definition: "A living organism is animate water." Indeed, our body is 3/4 of this substance. It is interesting that water contains even such "details" as bones. And water is not just present in our body, but plays one of the most important roles in almost all life processes. It is part of the blood, it participates in the work of the circulatory system, delivering nutrients and oxygen to the organs. Without water, we could not digest food. It cleaves even a poison like nicotine, as well as sugar and excess salt. It protects against overheating and removes wastes of life. And if without food a person can still "hold out" a month or two, then without water, he dies within a week. Why does this happen? Let's consider in more detail. 
Physiological functions of water
Perhaps, first of all, it should be said that,that water plays the role of a kind of "filler" for our body. Our appearance depends on it. After all, thanks to it, the organs retain a certain shape and "work" in a normal mode. The person reacts very sharply to the change in the water balance:
- reducing the amount of water in the body by only one percent leads to a strong thirst;
- if the moisture is less by five percent, there is a feeling of dryness in the mouth, the skin begins to wrinkle, there is a clouding of consciousness and even hallucinations are possible;
- if the body loses ten percent of water, this leads to a mental disorder, the swallowing reflex disappears;
- If a loss of 14 to 15 percent of moisture can occur, death occurs.
Another, equally important function of water isfood. It dissolves useful substances and, together with them, penetrates into cells, intercellular spaces and even the thinnest capillaries, providing them with all the essentials. Also, water participates in the process of digestion and cleanses our body of the products of vital activity. Leaving the body through the skin and kidneys, water simply "takes with itself" all the harmful substances that have accumulated in the body. Moreover, water is the main biological fluid. After all, it is precisely this environment in which the metabolic reactions and the constant process of restoration and destruction of living tissues are carried out. No less significant is the thermoregulatory role of this substance. What is thermoregulation? This is the body's ability to maintain a certain body temperature. Remember what the doctor tells you when you are sick. "Drink more fluids" - right? Water, evaporating from the surface of your body, helps to "knock down" the temperature. 
How much water do you need?
The need for water for all people is different. And it depends on many factors - from climate, age, health, work, nutrition, etc. Therefore, it is problematic to talk about exact figures. All the same they will be "averaged." So that's it. It is estimated that an adult, a healthy person living in the middle lane, daily loses about 3 liters of water. And the lost must necessarily be repaid. If the only thought that you have to drink as much as 3 liters, seems to you monstrous, do not despair! A lot of water we get from fruits, vegetables and other food. Therefore, the need for water "in its pure form" is about 1.5-2 liters per day. That is eight to ten glasses. Unfortunately, the vast majority of people drink only a small fraction of the required amount. And this is despite the fact that many scientists have already come to the conclusion that most of the "illnesses of the century" is associated with the violation of the drinking regime and, as a result, dehydration of the body. According to a number of studies, people who drink a lot of water are more enduring, restrained and more inclined to a variety of forms of creativity. By the way, our "smart" organism very clearly signals about water shortage. Only we often do not hear these signals and do not pay any attention to them. And in vain! The signs of dehydration are obvious and, for certain, are familiar to many. If you:
- the skin began to peel and dry;
- there were acne and acne;
- pores are clogged;
- there were "bags" under the eyes;
- pains in joints and back have begun;
- dizziness often occurs;
- you are constantly experiencing lethargy and fatigue;
- a dry cough appeared;
- beginning to "gallop" pressure;
- decreased efficiency and concentration of attention
... then it's time to think about whetherthe amount of water you consume. It is believed that the first glass of water should be drunk immediately after you wake up, on an empty stomach. Thus, right from the morning, "run" the purification process in the body. Further the daily norm is "taken" in small portions. Drink follows in small sips and, of course, only "live" - not boiled - water. Tea, coffee, juices - do not count. It's about drinking water. What other measures can be taken to avoid dehydration? Here are a few simple tips:
- if you are going on a trip and you know that for a long time you will not be able to drink - drink "in reserve", on the eve;
- being on the plane, try to drink at least one glass of water every hour. This is due to the fact that in airplanes very "overdried" air;
- in the summer, before you leave the house, be sure todrink one or two glasses of water. In doing so, try not to drink directly on the street, tk. this can lead to increased sweating. As a result, you will lose even more moisture;
- if you get sick, and you have a fever, drink as often as possible, even "through I do not want";
- remember that alcohol, coffee and smoking lead to dehydration of the body. For each serving of an alcoholic beverage or a cup of coffee, one glass of clean drinking water must be available;
- During pregnancy and lactation, there is a need for an additional amount of fluid.
A bit about the "eternal" ...
Also - which is especially important for women,watching their figure - it is believed that water helps to cope with excess weight. A glass of water drunk before eating dulls the feeling of hunger and reduces appetite. As a consequence, you will eat less than usual. This is especially important if you "sit" on a diet - there is something you want constantly! But during food from drinking it is better to abstain - water dissolves food and removes it from the body, which means, very soon you will again want to eat. In general, it is believed that you should drink only dry food - pies, crackers, sandwiches. Any mistress knows that how often do not sweep the floor - without wet cleaning still can not do. Without water, it is simply impossible to bring cleanliness. Our body also needs to be "washed". And not only outside, but also inside. It is water that flushes out all the toxins and toxins and allows to ensure, so necessary for health, purity in the body. However, do not forget that every question should be approached "wisely". In all the measure is needed. The excessive amount of liquid in the human body can bring no less harm than its lack. Large portions of drinking increase sweating, make it difficult to carry oxygen by blood and increase the burden on internal organs. When you use acute and salty foods, you are thirsty, but taking too much fluid can lead to a metabolic disorder. It is also not recommended to drink fatty foods with cold water - overflow of the stomach can lead to its breakdown - it's better to limit yourself to a cup of hot tea. Sweet juices on an empty stomach also increase peristalsis of the stomach and have a laxative effect.
Ordinary miracle
However, the phrase "Do not let yourself wither" isnot just an advertising slogan, but the real truth. During life, the amount of fluid in the body gradually decreases: the newborn child consists of water by 86 percent, and the elderly person - only by 50! Aging is, literally, drying out. Remember how the apple wrinkles and withers, if it lays on the table for a long time - the same thing happens to us. It is necessary to fight! Life originated in the water. "We carry the ocean in our veins," said the poet. And to save this life full to us will help a small, familiar and, almost unnoticeable, miracle - several glasses of clean water a day. They help to get rid of excess weight, improve the condition of the skin, hair and overall health. And, most importantly, for all this, it is not necessary to run to a pharmacy or department store and spend "mad" money. Miracle - that's it, very close. Just reach out. We advise you to read:
