1. A method of modifying a human subject'"'"'s endogenous circadian cycle to a desired state, comprising the steps of:
- determining the characteristics of a desired endogenous circadian cycle for said subject;
selecting an appropriate time with respect to the presumed phase of physiological markers of the subject'"'"'s present endogenous circadian cycle during which to apply a light stimulus to effect a desired modification of said present endogenous circadian cycle of said subject, wherein said stimulus comprises an episode of intermittent light consisting of at least two pulses of light of enhanced intensity separated by at least one pulse of light of reduced intensity andapplying said stimulus at said selected appropriate time to achieve said desired endogenous circadian cycle for said subject.

Abstract
The present invention is a method for modifying the circadian cycle of a human subject to a desired state including the steps of determining the characteristics of the desired circadian cycle, selecting an appropriate time during which to apply a light stimulus to effect a desired modification of the present circadian cycle, and applying the stimulus at the selected time to achieve the desired circadian cycle for the subject. The light stimulus of the present invention includes an episode of intermittent light consisting of at least two pulses of enhanced light separated by at least one pulse of reduced light.
