Background
  • Thalassotherapy, or seawater therapy as it is sometimes known, is the use of seawater and seaweed for a variety of cosmetic and medicinal purposes, from reducing the appearance of cellulite to relieving joint pain. The benefits of thalassotherapy supposedly reside in the minerals dissolved in sea water, including magnesium, calcium, sodium, iodine, silicon, zinc, selenium, sulfur, and fluoride. Advocates claim these minerals enter the body through pores on the skin and draw out toxins.
  • Thalassotherapy is a health and beauty treatment developed in France around 1969. The name of this therapy is derived from "thalassos," the Greek word for sea. It is sometimes classified as a form of hydrotherapy, a term that describes the use of water from any source to treat a medical condition.
  • Thalassotherapy is most commonly practiced at spas in countries surrounding the Mediterranean and Dead seas, which are thought to contain unusually large amounts of minerals.
  • Proponents claim that thalassotherapy offers many cosmetic and medical benefits. For instance, exposing the body to seawater supposedly reduces cellulite and encourages the body to lose weight. Advocates claim that this modality assists in the relief of back pains, increases circulation throughout the body and may treat hypertension, arteriosclerosis, asthma, bronchitis, muscle atrophy, and scabies.
  • Use of whirlpools, heated water and jet streams of water is thought to relax a patient, thus improving their quality of life for the duration of the treatment.

Theory / Evidence
  • Water from the Mediterranean and Dead seas is high in salt and magnesium. Advocates claim that exposure to high concentrations of these minerals invigorates the body, increases circulation and encourages weight loss.
  • A 2005 article by Merati et al. examined the physiological parameters of dipping patients into hot water with varying salt concentrations. The researchers found that patients dipped into hot salt water experienced an increased heart rate, but without vascular contraction.
  • A 2003 article by Tsuchiya et al. measured changes in blood lactate and pyruvate concentrations when healthy young men were dipped into seawater. Patients showed no change in blood lactate and pyruvate concentrations immediately after or 60 minutes after bathing.

Technique
  • The seawater used in thalassotherapy is usually warmed by the spa or health center before application on the body.
  • Underwater jets are sometimes used to target specific areas of the body, such as the back and neck. These jets expel water out of a special tube at a very high pressure. The result is a feeling of the water from the jet pushing into the skin. Distance spraying of seawater may target specific areas of the body, such as the buttocks or thighs. In this form of thalassotherapy, the patron stands on dry land as water is sprayed at them from a high-pressure jet, and some claim that it reduces the appearance of cellulite. Some centers create waterfalls in pools to achieve the same purpose. All of these types of thalassotherapy are designed to supposedly encourage circulation, provide a gentle massage of muscles and damaged ligaments, as well as increase the body's absorption of minerals in the water.
  • Some centers also offer pools of alternating hot and cold water, which is thought to increase the body's circulation.
  • Patients usually wear a bathing suit for treatments, although some centers allow treatments to occur without any clothing on.
  • Some treatment pools, such as those with massage jets, are intended for only one person at a time. However, other treatments, such as sitting in whirlpools, may occur in the presence of other patrons.
  • In some cases, a thalassotherapist may coordinate the delivery of an underwater jet stream, water temperature and other aspects of treatment with seawater. In other cases, patrons simply choose a treatment, which is performed by machines. The most accessible form of thalassotherapy involves sitting in a spa communal pool.
  • There is currently no certification process for thalassotherapists in the United States.
