balneology

Balneology is the science concerned with the therapeutic use of natural mineral waters, gases, and peloids (mud) for health and disease. It encompasses the study of the physical properties of waters, their mineral content, and their physiological effects, as well as the clinical application of treatments such as bathing, drinking cures, mud therapy, and inhalation of vapors. The therapeutic use is often termed balneotherapy, while balneology also covers research, diagnosis, and regulation.

Historically, balneology has roots in ancient civilizations; Greek and Roman physicians described baths, and spa towns in Europe flourished from the Middle Ages onward. In the 18th–19th centuries, balneology matured as a medical discipline, with systematic assessment of waters and peloids. Major spa centers—such as Bath (England), Vichy (France), and Karlovy Vary (Czech Republic)—became centers of treatment and research.

Treatments rely on heat, mineral content, buoyancy, and osmotic effects; peloids provide mechanical and thermal stimulation. Potentially therapeutic waters include thermal/meteoric waters rich in sulfates, bicarbonates, chlorides, and iron, among others. Some patients are treated with mud packs or peloids; inhalation therapies may use mineral-rich aerosols.

In modern medicine, balneotherapy is used as an adjunct for conditions such as osteoarthritis, low back pain, fibromyalgia, psoriasis, and dermatitis, sometimes within specialized spa clinics. Evidence varies: randomized trials show modest improvements for some musculoskeletal disorders, while results for other conditions are inconclusive.

Safety and regulation: Balneotherapy is generally safe when properly supervised and waters are appropriately analyzed. Contraindications include pregnancy in certain therapies, acute inflammation, severe heart or kidney disease, active infections, or open wounds. Water quality, temperature, and duration are important; some waters carry radiological or chemical risks that require regulation.
