Humankind has known about the therapeutic effects of mineral water since ancient times. Temples were built near mineral water springs, where the sick were treated the same way as today – diet, movement, baths and the drinking of water. Natural mineral water cures the body from the inside out.
Geological mineral waters mostly have a specific therapeutic effect, which depends on their chemical composition and also on the physical properties of the water.
- Therefore, iron-rich mineral water is used for anaemia and menstrual irregularities.
- Hydrocarbonate-rich waters help lower the pH of stomach acid.
- Sulphate and chloride-rich mineral water is recommended for the digestive system, the biliary and urinary system, and liver or kidney diseases.
- Iodine and bromine-rich water in is recommended as a cure for arthritis and some heart conditions.
- Mineral water rich in silicon compounds has an anti-inflammatory effect.
- Radon-rich mineral waters can be used for an underactive thyroid gland, stimulating fat metabolism and for chronic arthritis.
- Sodium takes part in the body’s hydration, acid-base balance and neuromuscular irritability. A sudden need for sodium in the body rises during hot weather and strenuous exercise. The body loses fluids, which in turn affects the loss of other minerals, like magnesium and potassium.
Low sodium content mineral water is the one in which the element content is lower than 20 mg/l, and high sodium content mineral waters are the ones in which sodium content exceeds 200 mg/l. People are generally warned about sodium content that is too high. That, however, is an overreaction, since sodium in mineral water is not found as sodium chloride (table salt), but is rather bound to other minerals or bicarbonates. In this way, the bicarbonate promotes the extraction of redundant sodium. Bicarbonate is not a mineral, but is an important ingredient of good, natural mineral water. Mineral waters that have flowed through limestone are bicarbonate-rich.
- Potassium helps in lowering high blood pressure, is important for skin health, and stimulates the kidneys to separate toxic surpluses. To some extent, potassium can be found in almost all mineral waters.
- Magnesium is a bioelement with a significant effect, the need for which mineral waters help to cover. Magnesium helps to regulate the work and circulation of the heart muscles and the metabolism of calcium and vitamin C. Mineral water is classified as rich in magnesium, when the amount of magnesium in it is 50 mg/l or more.
- Certain mineral waters stand out with elevated levels of calcium. Calcium is the body's design material; it is the most important mineral to the body in terms of quantity. Calcium regulates blood clotting, suppresses inflammation, relieves allergic reactions, and affects nerve and muscle activity. Activates the metabolic processes. In order to be able to speak of a high level of calcium, a litre of mineral water must contain at least 150 mg of this element.
- Other water parameters include the pH value of the mineral water (typically between 3 and 8), the temperature in use (typically 20˚C for cool waters, 45˚ C for hot water), the low radioactivity caused by radon, and the hydrostatic pressure of the water.
- Since mineral waters are also the source of several trace elements, particular attention should be paid to their content, as these elements are often needed in much smaller quantities by the body. Mineral water with a fluorine content of 1 mg/l is defined as fluorine-rich. Iron-rich mineral waters consist of more than 1 mg of iron per litre of water. Excessive consumption of these substances causes a number of problems in the body.
