Abstract
Systems and methods for adjusting a user's circadian rhythm are provided. In some embodiments, a system may be configured to obtain information relating to the user's present circadian rhythm and information relating to one or more anticipated times of sleep and/or wakefulness. The system may generate a model for estimating the user's circadian rhythm. The system may also generate a model for estimating the user's homeostatic sleep drive. Based on one or both models, the system may generate instructions for activating the light source to adjust the user's circadian rhythm.
Claims21
A system for adjusting a user's circadian rhythm, the system comprising:
- one or more input modules for collecting information relating to a user's sleep and/or wakefulness;
- a light source;
- a processor system including one or more processors that control the light source;
- a memory system storing one or more machine instructions, wherein the system is configured to:
- obtain information relating to the user's present circadian rhythm;
- obtain information relating to one or more anticipated times of sleep and/or wakefulness, for the user, over one or more days of a multi-day treatment program, the information relating to one or more anticipated times of sleep and/or wakefulness comprising information relating to at least one target to be achieved over the multi-day treatment program;
- based on at least the information relating to the user's present circadian rhythm, generate a Process C model that estimates the user's circadian rhythm over the multiple days of the multi-day treatment program;
- based on at least the one or more anticipated times of sleep and/or wakefulness, generate a Process S model that estimates the user's homeostatic sleep drive over the multiple days of the multi-day treatment program;
- based on at least the Process C model, the Process S model, and a Process L model that estimates a phase shift to the user's circadian rhythm that will result from light generated by the light source during the multi-day treatment program, generate the multi-day treatment program, the multi-day treatment program comprising instructions for activating the light source at different times over the multiple days of the multi-day treatment program while the user sleeps to adjust the user's circadian rhythm;
- and
- based on the generated instructions for activating the light source, activate the light source during the different times while the user sleeps to adjust the user's circadian rhythm.

A method for adjusting a user's circadian rhythm, the method comprising:
- obtaining information relating to the user's present circadian rhythm;
- obtaining information relating to one or more anticipated times of sleep and/or wakefulness, for the user, over one or more days of a multi-day treatment program, the information relating to one or more anticipated times of sleep and/or wakefulness comprising information relating to at least one target to be achieved over the multi-day treatment program;
- based on at least the information relating to the user's circadian rhythm, generating a Process C model that estimates the user's circadian rhythm over the multiple days of the multi-day treatment program;
- based on at least the one or more anticipated times of sleep and/or wakefulness, generating a Process S model that estimates the user's homeostatic sleep drive the multiple days of the multi-day treatment program;
- based on at least the Process C model, the Process S model, and a Process L model that estimates a phase shift to the user's circadian rhythm that will result from light generated by the light source during the multi-day treatment program, generating the multi-day treatment program, the multi-day treatment program comprising instructions for activating a light source of a sleep mask at different times over the multiple days of the multi-day treatment program while the user sleeps to adjust the user's circadian rhythm;
- and
- based on the generated instructions for activating the light source, activating the light source of the sleep mask during the different times while the user sleeps to adjust the user's circadian rhythm.
