Thermal cures and thalassotherapy have no proven effectiveness on the course of lupus but they can improve well-being. In some countries, some disorders (joint, muscular...) can justify a request to the social insurance fund or medical insurance, together with a medical prescription.

It should be noted that only the cost of the treatment are generally taken care of. Most of the accommodation costs and any travel expenses will remain at the individual’s expense, except in very specific cases.
