termál

Termál is a Hungarian term used to describe heat-related phenomena and places, particularly thermal water and thermal baths. In geology and spa culture, termál indicates groundwater heated by geothermal processes, often emerging as hot springs. The word derives from Latin thermalis, via Hungarian adaptation "termál" and is related to the global term "thermal." In everyday usage in Hungary and Central Europe, termálvíz refers to mineral-rich geothermal water used for therapeutic baths; termálfürdő denotes a spa facility using such waters.

Thermal waters form when groundwater percolates down, is heated by hot rock or magma, and rises to the surface. Depending on reservoir temperature and mineral content, waters may range from warm to hot (roughly 25–100°C). Common constituents include sulfates, chlorides, bicarbonates, silica, and sulfur compounds; these affect taste, odor, and reputed healing properties. The use of termál facilities spans recreation, rehabilitation, and wellness, often in purpose-built baths with swimming pools, saunas, and therapies.

Safety and regulation: Thermal waters are generally safe, but some may contain mineral or microbial constituents requiring monitoring. People with certain conditions should seek medical advice before use. Environmental management focuses on sustainable extraction and protection of groundwater resources.

History and culture: The spa tradition is strong in Hungary and Central Europe, with many termál baths dating to Roman times and expanding in the 18th–20th centuries.
