Thalassotherapy might be a popular wellness treatment in Europe, but most of us on the other side of the pond aren’t quite as familiar with it. Thalassotherapy gets its name from the Greek word thalassa, which means sea or ocean. The therapy utilizes seawater, spa therapy and the salty ocean climate to improve health and promote an overall sense of well-being.

The practice dates back to ancient Roman times, when soldiers used hot seawater baths to recuperate after battles. Thalassotherapy has grown in popularity since then and can now be found along most European coasts. It’s particularly popular in locations with a maritime climate, such as France, Spain and Greece, where seawater can be drawn locally and used in baths, pools and treatments.

Thalassotherapy can take many forms. Here are some of the most popular treatments.

Soaking: A key component of thalassotherapy is immersing yourself in seawater. Some treatments may also involve soaking in water that contains seaweed or sea mud.

Showering: Many treatments involve showering in seawater that contains minerals from the ocean. Practitioners often use hydromassage from high-pressure jets of water to soothe muscles.

Wraps, Scrubs and Masks: Thalassotherapy spas use a range of marine products in their treatments, such as a thalasso wrap, during which seaweed or marine mud is applied to the body, which is then wrapped in a hot blanket. Therapists may also use sea salt scrubs, mud masks and other aquatic products.

Exercising: Many thalassotherapy programs include aquatic exercise, such as swimming.

Breathwork: Thalassotherapy spas encourage visitors to inhale steam from seawater and to take in the sea air around them.

Ready to indulge in some deeply relaxing thalassotherapy treatments? Here are a few of our favorite seaside spas where you can soak up all the soothing benefits.
