BODY ILLUMINATION SYSTEM FOR CONTROLLING THE BIOLOGICAL CLOCK OF A MAMMAL BY RADIATION EXPOSURE OF THE SKIN

摘要

The invention relates to a method and body illumination system configured for controlling a biological rhythm of a mammal. The illumination system comprises one or more light sources configured for emitting light in a wavelength range of 400-480 nm. The body illumination system is configured for exposing a surface area greater than 0.5 m2 of the body to the emitted light. The body illumination system is configured such that the power density of the emitted light on the surface area of the body is greater than 125 mW/cm2. The method and system provide an illumination system capable of exposing a larger part of a body to radiation in a non-toxic dominant wavelength regime with a much greater power density in order to obtain effective control of a human biological rhythm within a reasonable period of time. The exposure of the skin of the mammal allows for the administering of the radiation without exposing the eyes of the person to the radiation, e.g. during sleep.
