Heliotherapy

Duties and responsibilities: consists of exposure to daylight or to specific wavelengths of light using polychromatic polarised light, lasers, light-emitting diodes, fluorescent lamps, dichroic lamps or very bright, full-spectrum light. The light is administered for a prescribed amount of time and, in some cases, at a specific time of day. One common use of the term is associated with the treatment of skin disorders, chiefly psoriasis, acne vulgaris, eczema and neonatal jaundice. Light therapy which strikes the retina of the eyes is used to treat circadian rhythm disorders such as delayed sleep phase disorder and can also be used to treat seasonal affective disorder, with some support for its use also with non-seasonal psychiatric disorders.

Education: he effect of heliotherapy on psoriasis skin lesions and arthritis was studied in a trial comprising 4 weeks of therapy in the Canary Islands and a 6-month follow-up period. A total of 373 patients participated in the heliotherapy and 361 patients completed the follow-up period. The severity of skin lesions was evaluated using a psoriasis severity index (PSI), and that of the arthropathy by using an arthritis index (AI). During heliotherapy, the PSI decreased significantly from the initial median value of 4.5 to the final value of 0.2. A reduction in the PSI of at least 75% was achieved in 84% of the patients. Guttate psoriasis improved significantly better than plaque-type or erythrodermic psoriasis. There was no correlation between skin type and improvement. Initially, 129 patients had symptoms of arthritis.
