[Biological effects of solar radiations].
Main biological effects of ultra-violet radiations are discussed. At a dermatological point of view, most of these effects are harmful: actinic erythema, cutaneous cancerogenesis (basal and spinous cell carcinomas, malignant cutaneous melanomas). Photo-immunosuppression and photoaging of the skin are discussed. Two benefic actions of sunlight are reviewed: synthesis of vitamin D3 and positive action of visible radiations on human psychism.
