Water is the cradle of all living things.It is unlikely that any sane person would argue with this statement. But at the same time, almost all people are sure that water is an absolutely simple and thoroughly studied chemical element H2O. However, in fact, this is not so. At all times, including modern times, water has been and is one of the most difficult mysteries for scientists. Scientists have been interested in the properties of water for decades, but they have not been fully clarified to this day. And this is not surprising - after all, water is an absolutely unique substance. For example, almost all substances contract when cooled. And water, on the contrary, expands. Or take density. In a frozen state, water has a much lower density than in a liquid state. And there are endless such questions.
The importance of water in the body
Also, scientists still have some unanswered questionscleared up questions about what role water plays in human life. But the fact that it is irreplaceable and the functioning of the body without water is simply impossible is undeniable. As is known, the human body consists of 70% water. Human bones contain about 22% water, lungs - 80%, heart - 75%, muscles - 60%, brain - 90%, blood and lymphatic fluid - 95%. Upon closer examination, scientists found out that in addition to the fact that the cell itself consists largely of water, it is also located in the intercellular fluid. And it is not surprising that if a person does not consume enough water and the cells are not saturated properly, the full functioning of the body is impossible, the person's well-being also suffers. It is water that is the basis of all drinks without exception that a person drinks. And this applies, in principle, not only to drinks, but also to all products without exception. For example, bread contains about 35% water, meat - about 60%, tomatoes - 90. And that is why it is not even worth mentioning that the body suffers greatly from a lack of water. If a person feels inexplicable extreme fatigue, drowsiness or extreme thirst, especially if the ambient temperature is not that high, most likely, you have the first signs of dehydration. And dehydration is an extremely serious danger to the human body. And very often it is the person himself who becomes the culprit of dehydration. For example, people believe that if they drink a lot of coffee, tea or beer, they will not be threatened by a lack of water. However, this is not true at all - many drinks, such as wine, beer, tea or coffee, not only do not saturate the body with water, but, on the contrary, contribute to the removal of water from the body, thereby contributing to even greater dehydration. There is also another widespread misconception among people that in winter the body requires much less water than in summer. However, such a drinking regime is a sure way to dehydration. The daily water requirement of an adult is at least one and a half liters. In hot weather, this requirement increases to three liters. Any person can independently calculate the average daily fluid requirement for their body. To do this, it is enough to remember that for every kilogram of weight the body should receive 40 grams of water. If you drink the required amount of water, you will not be afraid of dehydration or other complications associated with it. And believe me, these complications can be very, very serious.
Prevention of various diseases
Doctors also say that dehydrationof the body, especially if it is chronic, often provokes a variety of diseases, often quite serious. For example, cancer. The most recent studies by oncologists prove that chronic dehydration increases the risk of developing cancer by about 40%. Agree - quite an impressive figure. In addition, the amazing properties of water protect the human body from such misfortunes as diseases of the liver and kidneys, gall bladder. Medical statistics show that 67% of people suffering from such diseases had chronic dehydration. And, in addition, the amazing properties of water help the body cope even with viral diseases and flu. In order to reduce the risk of infection, doctors recommend that people increase the amount of liquid they drink by about 30% during epidemics and in the off-season.
Drinking water quality
However, the properties of water are undoubtedly directlydepend on its quality. A person can drink only clean water of proper quality, free of any harmful impurities. Many people are used to drinking tap water straight from the tap, without cleaning it. However, to our great regret, the state of most water supply systems in Russia, and not only in Russia, is so deplorable that drinking water without first cleaning it is extremely imprudent and dangerous for the human body. The vast majority of people mistakenly believe that tap water can be drunk simply by boiling it. However, this is far from true - simple boiling is not enough even to kill all the microbes. And it goes without saying that nitrates, phenol, pesticides and heavy metals remain in the water after boiling. Therefore, tap water must be purified using special filters. Such filters can be purchased over the counter. And, in addition, boiling has another very significant drawback. During boiling, calcium and magnesium salts, which are so necessary for the human body, remain on the walls of the kettle. After all, a person receives most of these salts from water. In addition to using special filters, doctors recommend using such a method of water purification as settling. Water should be settled for about 6 hours, only in an open container. The chlorine contained in the water will evaporate, and all those harmful substances, chemical elements, salts and heavy metals that are harmful to health will settle at the bottom of the container. Pay special attention to this fact - after two-thirds of the water has been used, the remaining water must be drained. If you do not want to bother with filters and settling water, you can use special purified bottled water for drinking, which is sold in almost all stores. Such water is already completely ready for use. By the way, doctors recommend using purified or bottled water for cooking. After all, if you cook food with tap water, all the harmful substances will still get into the human body and have a negative effect on it. Now, knowing the basic properties of water, you can make it your ally in the fight for your health! We recommend reading:
