A healthy body is primarily affected by its characteristics, and there is no life without water. How to distinguish boiling vs filtering water and make an invaluable contribution to your longevity and well-being?Tap water comes from various sources - lakes, rivers and reservoirs, passes through pipes for tens of kilometers, collecting dirt and chemicals. By the time it hits your glass, it has a lot of heavy metals and bacteria left in it, so it needs a thorough cleansing.
All about water: what and how much to drink.
Research shows that people began to drink tap water more often, thanks to the use of filters . 16% of people drink only bottled. Some respondents say that it is not safe to drink tap water, others simply do not like the taste. But is there a difference and which water is more beneficial for the body? We understand today's material.
It's no secret that water is essential to life. And the human body is 70% water - it is a mandatory substance for us, its lack can lead to dehydration and swelling. Water is needed for the functioning of the excretory (kidneys, liver) and digestive (stomach, intestines) systems.
American scientists substantiated the amount of water necessary for the normal functioning of the human body. There is a natural water balance in which a person loses up to two liters per day: the body accumulates substances that must be removed through the kidneys.
With proper nutrition , one liter of water is enough to remove these substances. In addition, about 100 ml comes out with feces. And, of course, a sufficient amount of water - about 900 ml - leaves the body due to evaporation from the surface of the skin. Two liters - that's how much fluid we have to compensate for.
In a special report from Harvard Medical School, they say that water supports the proper functioning of all organs of the body and performs many important functions, such as:
- delivery of nutrients and oxygen to cells ; _
- flushing out harmful bacteria from the bladder;
- help digestion;
- prevention of constipation;
- normalization of blood pressure;
- stabilization of the heart rate;
- protection of organs and tissues;
- maintenance and regulation of body temperature;
- maintenance of electrolyte (sodium) balance.
If a person drinks little water and fluids daily, there is a risk of dehydration. This may manifest as weakness, low blood pressure, dizziness, confusion, or dark urine.
Our grandparents believed that the most useful water is boiled water , as it is “clean”. Of course, all harmful bacteria are killed under the influence of high temperature, but the beneficial ones too.
And also, all the salts contained in raw water, after boiling, turn into an insoluble precipitate, and chlorine does form toxic compounds, which, if regularly ingested, can lead to serious diseases, including kidney stones and even oncology. So boiled water can be called empty and even harmful.
However, it must be remembered that water is a solution with a large amount of impurities, and during evaporation, the concentrations of these substances increase. But most of these impurities settle on the bottom and walls of the teapots. Water can be additionally defended before boiling or drinking, then part of the impurities will settle at the bottom of the container.
Boiling water kills bacteria and parasites, but it still contains toxins. Similarly, chlorine does not completely evaporate: some of it precipitates and combines with other chemicals. As a result, they act as carcinogens that cause inflammation. At the same time, the oxygen level in boiled water is lower than in raw water, therefore, with prolonged intake of such a liquid, oxygen deficiency develops - vitamins and microelements are absorbed worse, brain function slows down, as a result of which you become less attentive.
Experts distinguish three types of filters, and each of them in its own way affects the composition of tap water. For example, reverse osmosis filters completely remove chlorine and contaminants, but at the same time deprive the water of about 80% of trace elements. The ion exchange filter neutralizes scale and softens the texture, but dissolves salts and calcium. A compromise between a reverse osmosis system and ion exchange can be carbon filters. They remove toxins, kill bacteria, but at the same time retain all the beneficial substances and even further enrich the water with various minerals. The US Nature Protection Agency has officially recognized this method as the most effective and safe for health.
Various water filters are very fashionable now. But they are not a panacea either. Experts warn: modern filters really purify water from harmful impurities, but also kill bacteria. Ideal water without mineral salts disrupts the metabolic processes in the body, which can lead to diseases of the bones and the cardiovascular system.
Different types of filters use their own cleaning methods. Activated carbon filters do not remove all nitrates, dissolved minerals, bacteria and viruses in the water during absorption. However, the minerals dissolved in the water are not necessarily dangerous, and a significant proportion of tap water has already been treated. So it usually doesn't matter much if the smallest fractions of these substances slip through.
Some types of filters include a material called ion exchange resin, which can change the hardness of the water and can change the concentrations of calcium and magnesium ions.
The most important thing in using filters is their periodic replacement. An old filter not only cleans the water poorly, but can also make it worse . Moreover, such a liquid can become simply unsafe for humans.
Experts recommend filtered water for daily use. But it is important to change the filters in a timely manner, analyze the tap water in your home for the mineral-salt composition and choose the most suitable unit for you.
It is important for a person to maintain an acid-base balance. If disharmony is allowed, the number of harmful bacteria in the body will soon begin to increase rapidly, which will cause new diseases. The ideal acidity level of a liquid varies between 6.5 and 7.5. This range includes mountain spring water, which is purified without boiling and exposure to aggressive filters. You can get it yourself or buy it in a bottled form in a store. When buying, pay attention to the following factors:
