Thalassotherapy & Thermal Water Retreats
Discover the Healing Benefits of Purified Seawater and Thermal Spring Water
Water has always been central to health and wellness, with countless cultures throughout history harnessing its therapeutic properties for centuries. In today’s wellness world, two forms of water therapy stand out for their healing benefits: seawater and thermal spring waters. While both are integral to modern health retreats, each one offers distinct benefits based on its origin and composition.
Seawater therapy, or Thalassotherapy, involves the use of purified seawater, extracted from two metres below the ocean’s surface. The water is rich in marine minerals, such as magnesium, calcium, and potassium, known to ease joint and muscle pain, improve circulation, support detoxification, and restore balance to mind and body. The therapeutic effects of seawater are enhanced not only by its mineral content but also by its temperature, salinity, and the use of marine elements such as mud, algae, and is commonly used in treatments for their rejuvenating benefits, providing a natural way to detoxify, reduce stress, and boost vitality.
In contrast, thermal spring waters are sourced directly from deep within the Earth, and are rich in minerals, including sulfur, calcium, and magnesium, and known for their ability to relieve a range of chronic health issues. What makes thermal spring waters unique is their thermally heated composition, which helps to promote blood circulation, relieve joint pain, ease muscle tension. At many medical spa retreats across Europe, these natural spring waters are drinkable and often used as digestive aid to help improve metabolic functions, or are incorporated in treatments including hydrotherapy thermal baths, Thalasso pools, mud wraps and salt saunas. Both types of retreats offer an excellent opportunity to revitalise your body and mind, with the seawater retreats promoting relaxation and vitality through ocean-based therapies, and the thermal spring retreats helping restore your health from within through the natural healing waters of the Earth.
