Thalassotherapy (from the Greek word thalassa, meaning "sea") is the use of seawater as a form of therapy.[1] It also includes the systematic use of sea products and shore climate.[2] There is no scientific evidence that thalassotherapy is effective.
A particularly prominent practitioner was Dr. Richard Russell,[3][4][5] whose efforts have been credited with playing a role in the populist "sea side mania of the second half of the eighteenth century",[6] although broader social movements were also at play.[7]InPóvoa de Varzim, Portugal, an area believed to have high concentrations of iodine due to kelp forests, and subject to sea fog, the practice is in historical records since 1725 and was started by Benedictine monks; it expanded to farmers shortly after.[citation needed] In the 19th century, heated saltwater public baths opened and became especially popular with higher classes.[8] Others claim that the practice of thalassotherapy is older: "The origins of thermal baths and related treatments can be traced back to remote antiquity. Romans were firm believers in the virtues of thermalism and thalassotherapy".[9]
The therapy is applied in various forms, as either showers of warmed seawater, application of marine mud or of algae paste, or the inhalation of sea fog. Spas make hot seawater and provide mud and seaweed wrapping services.
