Indoor salt water baths followed by artificial ultraviolet B-light for chronic plaque psoriasis: abridged Cochrane review.

It has been suggested that indoor salt water baths with exposure to artificial UVB, may benefit patients with psoriasis.1 Artificial exposure to ultraviolet B-light (UVB) while soaking in an indoor salt bath, also called balneophototherapy, could simulate the natural exposure to the sun while bathing in the Dead Sea.2 However, the evidence underlying clinical efficacy, such as longer remission from disease and higher dermatology-related quality of life, has not yet been clearly evaluated. In a Cochrane review,3 we evaluated whether the combined application of indoor salt bath and ultraviolet B-light (UVB), also called balneophototherapy, improve the skin of patients with chronic plaques psoriasis when compared against UVB alone.
