Abstract
Solar phototherapy for chronic skin diseases, also called dermatological heliotherapy, has a long tradition. Modern dermatological phototherapy by artificial ultraviolet (UV) sources originally evolved from heliotherapeutical experience. Nowadays natural solar phototherapy is still performed during dermatological climatotherapy. A study in the Alexander clinic in Davos, 1,560 m above sea level, established low solar UV clearance doses for psoriasis of cumulative 1,042 J/cm 2 UVB and 41.51 J/cm 2 UVA. Comparably much higher UVB doses are needed if using artificial UVB irradiation for psoriasis treatment. The high therapeutical efficacy of natural solar irradiation during high mountain climatotherapy could be due to, beside additive effects of various climatotherapeutical factors, particular photoimmunological actions of the broad (complete) solar spectrum, possibly also to the special spectral distribution of the mountain sun.
