Different modalities of spa therapy for skin diseases at the Dead Sea area.

BACKGROUND Balneology and spa therapy, although not accepted as well-established treatment modalities in dermatology, are used throughout the world. The therapeutic properties for skin and rheumatic diseases of the Dead Sea area may be attributed to unique climatic characteristics and unique natural resources. The mechanisms by which a broad spectrum of diseases are alleviated by spa therapy may involve mechanical, thermal, and chemical effects. OBJECTIVE To review and discuss various spa therapy modalities, used at the Dead Sea area for a wide spectrum of skin diseases. CONCLUSIONS Existing evidence indicates the therapeutic potential of Dead Sea spa therapy modalities for psoriasis and psoriatic arthritis. A beneficial effect is hinted at for other skin diseases, but the absence of relevant methodological and clinical information precludes the drawing of any scientific conclusions. It is essential to establish therapeutic guidelines to determine the optimal treatment modality for each disease, and the optimal protocol of each treatment component, adjusted individually for each patient, with respect to remission and long-term adverse effects.
