Abstract: A method of determining and administering therapies responsive to a circadian rhythm of a user including receiving an indication of a therapy to be administered to the user, identifying one or more periods during a circadian cycle during which administration of the therapy is preferred, defining a circadian administration time, receiving an indication of a normal circadian rhythm of the user. determining the position of the circadian administration time within the normal circadian rhythm of the user, defining a user circadian administration time, determining a time of day corresponding to the user circadian administration time, defining a clock administration time, and at least one of providing an indication to the user to administer the therapy at the clock administration time and administering the therapy to the user at the clock administration time.

Abstract: A circadian rhythm shifting method to improve future therapy effectiveness including receiving a future therapy indication, identifying a circadian cycle period that performance of the therapy is preferred, receiving a user normal circadian rhythm indication, defining a user circadian performance time range, identifying a circadian shift to change the user circadian performance time range, defining a user circadian shift protocol to cause the identified circadian shift, and providing an indication to perform an activity of the user circadian shift protocol.

Abstract: A method of determining and presenting a protocol for adjusting a circadian rhythm of a user comprising receiving an indication of an intended circadian shift comprising a shift magnitude, receiving an indication of a user circadian phase, defining a user circadian shift protocol responsive to the shift magnitude and the indication of the user circadian phase, the user circadian shift protocol comprising one or more activities scheduled to be performed at a certain date and time, the activities comprising at least one of a light exposure or light avoidance activity, a chronobiotic activity, a nutritional consumption activity, a physical activity, and a rest activity. The method may further provide an indication to perform each activity on a user device.

Abstract: The present invention is a method for modifying the circadian cycle of a human subject to a desired state. The method includes the steps of assessing the present circadian cycle of the human subject, determining the characteristics 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.
