Thalassotherapy is the French sea-water spa tradition. Mineral-rich seawater, heated and pressurised, used in therapeutic protocols. The luxury hotels that take it seriously dedicate full programmes — 5-7 day treatment courses with results.
What thalassotherapy delivers
Heated seawater treatments (35-37°C) believed to: reduce inflammation, improve circulation, treat rheumatic conditions, support post-injury recovery, address skin conditions, manage stress.
Treatments typically include: hydrotherapy pools, jet massage showers, seaweed wraps, marine mud, and underwater massage. Often combined with nutrition consultation and medical supervision for multi-day courses.
