Abstract: This invention relates to methods and apparatus to control the light exposure of the skin. One objective is to increase the exposure during periods of common deficient exposure such as for dark skin persons on winter days in areas far from the equator. Another objective is to decrease the exposure during periods of common overexposure such as for light skin persons during spring and summer days in bright environments. A novel feature of the invention is the use of lamps for whole body irradiation while showering or bathing during dark seasons. The whole body exposure enables the use of very low irradiance levels to provide an enhanced probability of beneficial effects and to reduce the possibility of harmful effects of the ultraviolet light Another novel feature is the use of an adjustable ultraviolet light transmitting building window or automobile sunroof to increase the sunlight exposure on cold days when a deficiency in exposure due to closed windows is common.
