Which water is healthier

Fresh water sources occupy about 3% of the Earth's surface. If we compare it with the water of the seas and oceans, then fresh water bodies occupy 5 thousand times less in volume. Only 1% of fresh water bodies are suitable for human consumption. It is expected that in 2060, about 80% of the population may experience a drinking water shortage.

A person needs to drink water every day, otherwise its deficiency can lead to dehydration. On average, the body needs 2-3 liters of water per day, or 30-40 ml per 1 kg of body weight.

What kind of water do we drink?

Perfectly pure water does not exist. It contains a large number of bacteria, fungi, microorganisms, organic compounds.

The water that flows from the tap cannot be called high-quality and healthy. In 80% of cases, this is chlorinated water. Chlorination is a way to disinfect water. It is toxic to microorganisms, so it has been used for the last half century. However, what is dangerous to microorganisms can be dangerous to humans. Chlorine is harmful because it dries out the skin, contributes to the formation of wrinkles, and is also likely to develop kidney and bladder cancer. Therefore, it is not recommended to cook, let alone drink, raw chlorinated water. In this case, the water can be settled for at least 1 day, or at least 30 minutes before starting to use.

Most tap water is very hard due to its calcium salt content. There is no centralized softening of water in our country. Such water must be boiled or passed through a filter. Boiling for a long time will soften the water.

What kind of water to drink: raw or boiled?

The vast majority of people are accustomed to boiling water in order to increase its usefulness, or at least get rid of the microbes contained in it. But is boiled water really that good? The main disadvantage of boiled water is that it is almost completely deprived of oxygen, which is so necessary for our cells. Many experts call boiled water "dead". During boiling, useful salts precipitate, which no longer dissolves. When chlorinated water is boiled, chlorine is converted into dangerous toxic compounds that negatively affect the functioning of internal organs.

Raw water is preferable for humans due to the content of trace elements in the form of salts, but only if it is purified from impurities. Water that is purified by the central water utility and brought up to the requirements of regulatory documents for the quality of drinking water is not the best option for humans. Therefore, it is better to filter or settle raw water. The optimum settling time is at least 2 hours. In order to use a water filter, you must first analyze the water in order to know what it needs to be purified from. Different filters have different cleaning characteristics. A properly selected filtration system will provide your home with clean water.

Good quality water sources

Besides boiled and filtered water, there are several other sources of quality water.

Store water - safe but expensive

Store water is unlikely to contain rust or chlorine, it is purified by special systems, due to which the desired level of quality is achieved. Mineral water is extracted from natural sources and is rich in various trace elements and useful compounds. Mineral water can vary in composition and is not suitable for everyone. In some cases, drinking mineral water can lead to ailments. In case of illness of internal organs, the use of mineral water is prohibited. In addition, it is not recommended to drink mineral water on an ongoing basis, no matter how openly every producer of mineral water says about it. The cost of store water, especially recently, is quite high (from 15 rubles per 0.5 l).

Bottled water - quality assurance

The vast majority of offices are equipped with dispensers with bottled water, which has also begun to be used at home. This is a very convenient method. Installing a cooler allows you to supply a large number of people with a quality water source. After all, manufacturers are under strict state supervision. You can choose and install a convenient water cooler from a large number of offers on the market. Water coolers can be purchased at household appliances stores, for example, in Moscow, you can go to the Technosila chain of stores, the Media Markt metro market, the Eldorado chain of stores, etc. You can also make a convenient order via the Internet. It is not difficult to buy a cooler.

Well water is a luxury for owners of country houses

Well water is available to villages and country house owners. The costs include the construction of a well, drilling a well (about 15 thousand rubles - up to 20 meters) and payment for electricity in the case of using an electric pump. This water is relatively safe. At greater depths, it is less likely to encounter pesticides in its composition. Shallow depths can be a risk, as harmful impurities can seep through the soil along with rainwater. Therefore, you need to drill a deep hole.

Spring water is the least available source of quality water

Spring water is most often crystal clear and safe and free. But the fact is that there are very few such water sources. One may not even know about the existence of such a source, while it is nearby. The spring water tastes very pleasant. As a rule, such sources are located in impassable places.
