METHOD FOR MODIFYING OR RESETTING THE CIRCADIAN CYCLE USING SHORT WAVELENGTH LIGHT

摘要

The present invention is a method for modifying the circadian cycle of a hum an subject to a desired state. The method includes the steps of assessing the present circadian cycle of the human subject, determining the characteristic s of a desired circadian cycle, selecting an appropriate time during which to apply a stimulus of light to effect a desired modification of the present circadian cycle, and applying the light stimulus at the selected appropriate time to achieve the desired circadian cycle for the human subject. The stimulus of light comprises monochromatic short wavelength light (446-483 nm ) or white light substantially comprising short wavelength light.
