In conditions of normal air temperature and with moderate physical exertion, it is recommended to drink 2-3 liters of fluid per day, including the water contained in the products.
If you are used to consuming at least three liters of free fluid per day (and at this dose, even any healthy drink will become harmful), it is better to stop at a neutral option – purified drinking water. As a rule, such water, sold in bottles or canisters, is ordinary tap water, but purified from impurities (both harmful and beneficial) as much as possible. Carbonated drinking water quenches thirst well, and many housewives use non-carbonated water for cooking.
Speaking about the degree of purification of drinking water, distilled water can be considered ideal. However, it is not. Water devoid of salts can unbalance the body. Without trace elements, which are contained in ordinary water and absent in distilled water, such important body functions as the construction of new cells, the transmission of hereditary information and the transmission of nerve impulses are not performed.
Not even distilled, but simply “soft” water (the use of which manufacturers brag about) is not an absolute good for the body. Its regular use in food leads to fragility of bones, caries, a decrease in the overall resistance of the body – due to a lack of mineral salts in it.
Mineral water
Mineral waters have the best ability to quench thirst.. After all, it is known that the body’s need for water is largely determined by the need to replenish the reserves of mineral salts that the body loses with sweat and urine.
It is customary to call mineral waters of natural sources, with a high content of minerals and (or) with special healing properties.
Mineral waters are:
-
carbonic (Borjomi, Dilijan, Luzhanskaya No. 1, etc.);
-
sulfate (Batalinskaya, Ashgabat, Moscow, Ufa, etc.);
-
chloride (Minsk, Omsk, Tyumen, Druskininkai, etc.);
-
complex composition (Essentuki No. 4, 17, Novoizhevskaya, Smirnovskaya, etc.);
-
containing trace elements: iron, iodine, bromine, lithium;
-
radioactive, containing radium, radon;
-
biologically active.
Mineral water is not only a therapeutic and prophylactic remedy for many diseases (you can always find which ones on the label), but also just a drink that quenches thirst well. For better absorption of mineral water, it is advisable to drink slowly and in small sips.
Cold (below 20 degrees) water does not quench thirst because it is too cold for the stomach, which never goes below 36 degrees.Cold water is almost not absorbed until it warms up to body temperature. Ideal for quenching thirst, water should have a temperature of 20-25 degrees.
