Natural mineral waters are waters that contain more than 1 gram of ingredients per liter, or even greater amounts of ingredients that are not regularly found in groundwater or in surface waters.
In Roman times, mineral waters were used for bathing, healing and recovering. They were used by all Romans: Roman soldiers, the rich and the common people. In the Middle Ages, the mineral water was not so commonly used anymore. The revival of mineral water usage occured in the 18th century and lasts until today.
The science of balneology (lat.balneum = bath, grč.logos = science) was developed over the years. Balneology studies the natural mineral water as one of a natural healing factor.
According to the main characteristics, the natural healing factors can be divided in climatological, marine and balneological. According to the usage of natural healing factors, there are three different medical treatments: climatotherapy, thalassotherapy and balneotherapy.
Balneotherapy applies natural mineral water and other healing balneological factor for medicinal purposes. It is used in recreation and in health tourism.
Mineral water has a beneficial effect on preservation and improvement of health, improvement of the quality of life and prevention, treatment, recovery and rehabilitation of various diseases. Croatia is rich in mineral water springs and has 18 balneological health destinations.
Effects of the mineral waters are divided into mechanical, thermal and chemical. They have a profound impact on the human body and can lead to overall physical and psychological rehabilitation.
The immediate effects of mineral water depend on their chemical composition and physical properties. Different types of baths cause different reactions in the body.
Mineral waters, according to the content of certain trace substances, radioactive substances and gases, can be divided in: sodium, calcium, fluorine, iodine, magnesium, sulfur, iron, hydrogen carbonate, chloride, sulfate, radon and radioactive waters.
Geothermal water is one of the natural sources of heat. The temperature of the geothermal waters that were discovered by deep drilling ranges from 23 to 170 ° C. Given the large range of temperature, geothermal water in Croatia could be and already is used in many ways and in different sectors.
