Water is the source of life!
Our world consists of 70-90% of water. It is the basis of life on the planet and has an impact on virtually all processes. Our planet is covered by two thirds of water.
This is one of the simplest and at the same time the most complex substance on the planet. She devoted a lot of scientific works, but all the secrets of the water are not yet open.
For man, water is the second component after the air necessary for life. A person can live without food for more than four weeks, and without water will last no more than seven days. To maintain the water balance, take 2-3 liters of liquid.
Today, many scientists believe that life is a struggle for water. In infancy, the child’s body consists of 80-85% water. When reaching adulthood, 70-75% of water remains in the human body, in old age this figure decreases to 25%. That is why in order to prolong youth it is necessary to drink clean water. Water will help make normal metabolic processes feel good. And in truth, the quality of life depends on the quality of water!
Here is just a small and far from complete list of “duties” of water in our body.
Water:
- Moisturizes the air.
- Regulates body temperature.
- Provides delivery of nutrients and oxygen to all cells of the body.
- Protects and buffers vital organs.
- Helps to transform food into energy.
- Helps nutrients to be absorbed by organs.
- Displays slag and waste processes of life.
The composition of water is important. For drinking and cooking only fresh water with a total mineralization of up to 0.5 – 1 g / l is suitable. Sometimes, in limited quantities, the use of mineral water (for medicinal purposes) with increased salt content is possible. The human body quickly adapts to the change in the salt composition of drinking water. However, the process of habituation requires some time. Therefore, with a sharp (and even more frequent) change in the characteristics of water, there may be disturbances in the activity of the gastrointestinal tract, known in the people as a “disease of travelers”.
If you look globally, humanity now consumes 7-8 billion tons of water every day. If humanity will use water rationally, then this resource is inexhaustible.
Today there is a problem of clean quality water on the planet.
The most common pollution in water sources are nitrites, phenols and oil products, compounds of copper, zinc, manganese. On the territory of Ukraine, the water reserve, which consists of dozens of small rivers reaches 2-20 million. A significant “contribution” to the state of quality of surface water is made by industrial enterprises. The total annual discharge of wastewater into the watercourses is 15.6 km3 / year, including utilities, whose water quality has its own characteristics – 3.8 km3 / year. The issue of clean water for Ukrainians is very urgent. Specialists of the Kiev Institute of Ecological Hygiene and Toxicology. L. Medved says that in the water we drink, there are hundreds of organic compounds and heavy metals, harmful to the body. Methods of water purification, which are used at most water intakes, only relatively provide the availability of water for drinking. Some water treatment technologies have their own, often unconditional disadvantages. For example, the use of chlorine can lead to the formation of mutagenic and carcinogenic organochlorine compounds. And the use of traditional coagulant – aluminum sulfate (or alternative) enriches drinking water with aluminum ions, which have a neurogenic effect on the human body.

Nothing remains, how to use tap water only for household needs, it is better to buy drinking water.
