What is thalassotherapy?

Thalassotherapy is wellness treatment using seawater and the marine environment: the word comes from the Greek thalassa, meaning sea. Formal versions run in coastal spas: warm seawater pools, seaweed wraps, salt scrubs, marine mud. The premise is that mineral-rich seawater (magnesium, potassium, iodine) relaxes muscles and skin in ways fresh water does not. The practice took root in French seaside towns in the 1800s and is riding the wellness-travel wave back into fashion. The informal version needs no spa. Float in 84-degree Caribbean water, swim before breakfast, sleep beside an open hatch with salt air moving through. A charter delivers the raw ingredient all day. Explore a wellness charter.
