What can be more accessible than water? Is that the air. And to appreciate what is available, we somehow are not used to it. Well, water and water, not gold after all, is not a magical elixir, not a magical crystal. For this popular philistine opinion, we, alas, lose sight of what truly fantastic possibilities are possessed by all the known transparent liquid without taste and smell. After all, the use of water in the human body is truly invaluable!
Few people know that the human body is never in a hurry to signal the lack of moisture. In addition, the brain often confuses and instead of the button "thirst" presses the button ... "hunger". With age, the body reports thirst less and less, although it has a whole arsenal of signals about the lack of moisture: headaches, chronic fatigue, constipation, high blood pressure, distracted attention. If such ailments are repeated with an enviable regularity, and you also do not regularly replenish the water supply, here and to illnesses nearby. Doctors say that those who drink little water, are threatened with a whole bouquet of serious ailments in the human body.
Especially dangerous if an insufficient amount of fluid is consumed by a man. After all, representatives of the strong half of humanity lose an average of 700 ml of fluid per day more than women. And first of all it affects the urogenital system. So, if you do not want your beloved husband to run to a urologist, how to work, often drink it with water. For women, the imbalance of water in the body is fraught with the loss of external attractiveness. What women do not do in the pursuit of youth, forgetting about the simplest way - to drink more water to restore beauty to the skin, hair and body. It turns out that all genius is simple. Now we will understand when, what and how much to drink, so that the human body benefits from water:
- Within a day, regardless of whether you are thirsty, it is advisable to drink 2 to 3 liters of liquid. If you want to calculate a more accurate figure, use this formula: 40 ml of drinks for each kilogram of weight.
- In hot weather, you need to increase the daily dose of drinking water, because the body loses moisture during this period and in the form of sweat.
- More liquid for obvious reasons is required for pregnant and lactating women, unless, of course, this does not contradict individual medical indications.
- In a more active replenishment of the water reserve in the body, all those involved in sports (liquid comes out in the form of sweat), air travelers (in airplanes of very dry air) and sick people need it.
- Almost all specialists agree that it is very useful to drink a glass of water in the morning on an empty stomach. Plus, drink better before meals (20 to 30 minutes), and not after it. Most of the drinks drunk at night, remains in the body and in the morning "crawls out" in the form of edema.
- Topical question: which liquid is most preferable? Of course, quality water! On the second place are juices, but not concentrated, but diluted with the same water. But other liquids should be taken into account only if your doctor tells you to count each gram of moisture that has got into the body. In addition, if the drink contains at least sugar, then formally it already belongs to the category of food. About soups and say nothing.
On the water, which by all parameters can be considered qualitative and useful for the human body, the conversation is special. In our taps, water, as a rule, comes from surface water bodies (reservoirs, streams, rivers and lakes), less often - from underground sources. Regardless of origin, this water is polluted by a multitude of impurities. Among which there are also very toxic. In tap water can contain more than 2100 pollutants. The most dangerous are chlorine, pesticides and parasites. Chlorine, as is known, has bactericidal properties, but some of its compounds are carcinogenic. Pesticides are capable of provoking the development of malignant neoplasms. In tap water, carbon, lime, aluminum phosphate phosphate is often added specifically to disinfect it.
In order to make tap water safe for consumption, it can be boiled for 3 to 5 minutes. But recent studies have shown that boiled water, the human body, alas, poorly absorbs. Therefore, it is more reasonable in this situation to use an individual filter for water purification.
Today you can buy a household filter in many stores. However, in order not to make a mistake with a choice, you just need to know some nuances. For example, the most reliable means for disinfecting water and absorbing chlorine is activated charcoal. But it can be different. Even at the end of the last century, scientists determined that the highest level of sorption (that is, in simple terms, the ability to absorb harmful impurities present in the water) is charcoal obtained by roasting coconut shells. Such coals are found in many domestic filters. However, when buying a filter, specify about its possibilities with the seller and on the Internet. Russian filters of this family make it possible with a guarantee to purify the water of the residual chlorine and a number of other harmful compounds that may appear in the tap water after traveling over many kilometers of rusty pipes.
You can also choose the most optimal type of filter element in a particular situation. First and foremost, this applies to cute "jugs" - the most popular and common home filters. With the onset of spring and summer season, such filters once again demonstrate the convenience of use. They are light and compact, so they can easily be carried with them from the city apartment to the dacha and back. Such filters do not require special care: all you need to do is change the cartridge in time. There are several modifications of cartridges - for water purification of various types. There are universal filters that are suitable for most of the city's apartments. But too "hard" water can be mitigated with the help of other special cassettes. And for the prevention of fluoride deficiency, so necessary for our teeth, it is better to use a cassette with a fluoridating effect.
But no matter what heaped filters are not produced, the most useful for the health of adults and especially children is the natural water extracted from underground sources. And if you add ice (prepared from the same water) in such water, or you first freeze it in a freezer, and then wash it with whitish ice sheets and defrost the transparent part, you can not only not
rest on their health, but also look younger. Most people do not have the opportunity to manually recruit water from an underground source. Therefore, you can buy water for drinking in the store. What labels on the label should attract you, and which ones should be repulsed?
- Drinking water is slightly better than just boiled water from the tap, because it is cleaned of everything that can and can not be. Only decontaminating or preserving ingredients can be present in it.
- Mineral water , in theory, of natural origin. Therefore, the source is required. However, mineral water is sometimes called purified and artificially mineralized water. It is less useful than natural.
- Mineral water is a dining room, a medical-dining room and a medical one . The latter two varieties are advisable to drink only on the advice of a doctor and in small quantities. These three types of water differ in the degree of mineralization. And only table water with the lowest concentration of mineral salts (up to 0.5 g / l) is guaranteed not to cause harm to health with constant use.
- What mineral components should be present in high-quality mineral water? These are calcium, magnesium, potassium, sodium (in very small amounts), fluorine, iodine.
- For children under 3 years old it is advisable to buy a special one - children's water . The standards for its production are much higher than those for adults. So, children's water under no circumstances should not be chlorinated and aerated. Also, according to the regulations, silver is not allowed for its purification. Water for children is usually cleaned with ultraviolet or ozone. A concentration of sodium in children's water should not exceed 20 mg / l.
- Carbonated water , in general, is not very useful for adults and children. You can decide whether to buy such products. But remember that if you drank a soda after a meal, then the unpleasant sensations in the gastrointestinal tract are guaranteed almost certainly.
The labels on the bottles should be treated very carefully, since falsification of mineral water is one of the most profitable types of underground business today. According to statistics, at least 25 percent of bottled water sold is tap water. If on the label you find terms such as artesian, underground, natural, spring water, be sure to note whether the source is listed. If not specified, it is better to refuse the purchase.
Following these recommendations on the benefits of water in the human body, you will always be young, beautiful and healthy!
