Water is the source of life on Earth. It was in the ocean that living cells appeared. The human body is 80% water, therefore, without it, he can not live. It is this life-giving moisture that helps the existence of all plant and animal organisms. In addition, water is the most amazing substance on Earth. Only it can exist in those states: liquid, solid and gaseous. And even in its usual form, it is also diverse.
Few people on Earth know what water is. But not differing from each other externally, its various species have special properties. Being the most common substance on Earth, it is found in every corner of it in its various manifestations.
What types of water are
This fluid can be classified according to various criteria. Water can be different depending on the place of its origin, composition, degree of purification and scope.
1. Types of water by its location in nature:
- atmospheric - these are clouds, steam and precipitation;
- water of natural sources - river, sea, spring, thermal and others.
2. Types of water in relation to the surface:
- groundwater - artesian, groundwater and others;
- surface, or water of all reservoirs.
3. Types of water by its chemical composition:
- by the presence of calcium and magnesium, it is soft and hard;
- the number of hydrogen isotopes emit light, heavy and superheavy water;
- according to the presence of various salts, the water can be fresh and salty, seawater is also given a separate form;
- There is completely purified water - distilled;
- if it contains an increased content of biologically active minerals and trace elements, it is called mineral.
4. What is the water by its degree of purification:
- distilled is the purest, but not suitable for human consumption;
- Drinking water is a healthy fluid from wells and artesian wells ;
- tap water comes into the house from various reservoirs after the cleaning procedure, but often does not meet hygiene standards, therefore it is considered household;
- filtered water is ordinary tap water passed through various filters;
- There are still sewage contaminated in the process of human life.
5. Sometimes people treat water in various ways for medicinal purposes. The following types are obtained:
- ionized;
- magnetic;
- silicon;
- shungite;
- enriched with oxygen.
Drinking water
The types of fluid that a person consumes are the most diverse. In ancient times, people drank water from any fresh natural source - a river, lake or spring. But in the last century, due to economic activities, they have become contaminated. And a person is not only looking for new sources of clean drinking water, but also comes up with ways to clean dirty water. So far many groundwater, which lies deep, and artesian springs have not been contaminated, but this life-giving moisture is not accessible to everyone. Most of them use ordinary well or tap water, the quality of which is often very low. It can contain various impurities, bacteria and even hazardous chemicals. Therefore, it is better to purify drinking water in any convenient way.
Ways to clean drinking water
1. Filtration may be mechanical, chemical or electromagnetic. Most often they use carbon filters, they are the cheapest and easiest to use. During filtration, water is freed from impurities of sand, metal salts and most bacteria.
2. Boiling is most often used to disinfect water. It does not protect against impurities. Therefore, it is recommended to defend water during the day before boiling and not to use the precipitate.
3. In recent years, water purification with the help of various substances has become widespread: shungite, silicon, silver and others. So it is not only disinfected, but also acquires healing properties.
Mineral water
For a long time, a person has discovered sources in which fluid has various healing properties. Having examined such water, people found out that it contains an increased content of various minerals and trace elements. It was called mineral. Near such a spring sanatoriums and medical institutions were built. Often people drink it and just like that, not knowing that it is different in composition and its effect. What is mineral water?
- The dining room contains a small amount of mineral salts. It can be used as ordinary drinking, without restrictions. The degree of its mineralization is up to 1.2 g / l. Many people drink it constantly, not suspecting that it is mineral.
- Table-treated mineral water can also be used without restrictions, if the degree of its mineralization does not exceed 2.5 g / l. If it is higher, then you can drink it no more than 2 glasses a day. Such mineral waters as Narzan, Borjomi, Essentuki, Novoterskaya and others are very popular.
- Healing mineral water can be used only as prescribed by the doctor, because its different composition affects the body in different ways and helps with certain diseases. There are also many contraindications to its use. And if the degree of mineralization of such water exceeds 12 g / l, then it can be used only externally.
What is thermal water
If underground waters pass through hot volcanic layers before they reach the surface, they are heated and saturated with useful minerals. After that, they acquire healing properties known to people since ancient times. In recent years, thermal water has been increasingly used for treatment and recovery. Its species are not very diverse, mainly it is divided by temperature.
Near many thermal waters, hospitals have been built. The most famous of them is the Karlovy Vary spa, as well as sources in Iceland and Kamchatka.
Healing fluid
Speaking about what water can be, it is impossible not to mention those species that magically heal many diseases. Since ancient times, in many nations there were legends about living and dead water. And in recent years, scientists have found that it really exists, and even received such a liquid using special electrodes. A positively charged water is called dead and has a sour taste. It has disinfecting properties. If the water is charged with negative ions, it will acquire an alkaline taste and healing qualities. Such water was called living. In addition, the liquid acquires healing properties when exposed to a magnetic field, immersion in it minerals of silicon or shungite.
Not all people know what water is. Unfortunately, many of them do not even suspect that this life-giving moisture can cure them of many diseases.
