We cannot expect the same effectiveness as in thermal baths where the therapeutic effects are linked to the chemical composition of mineral waters, or that thalassos which derive their benefits from the marine environment. Especially since, for these two types of cure, the presence of a multidisciplinary medical team (doctor, physiotherapist, nurse, dietitian …) is an integral part of the medical benefits. But to say that these treatments are useless … They bring relaxation, pleasure, and it is not nothing in our stressful daily life! Finally, whether it is mineral, sea or tap, water remains an essential element of well-being: due to weightlessness, the body is lighter, movements are therefore easier while protecting our joints.
