Patch system for monitoring and enhancing sleep and circadian rhythm alignment

A system for aligning an about 24 hour circadian phase of one or more subjects to a desired schedule, the system comprising:

• an olfactory dispensing unit configured to dispense olfactory agents;
• a control unit configured to actuate the olfactory dispensing unit and store data from one or more sensors, wherein the one or more sensors are configured to perform one or more functions selected from the group consisting of estimating and tracking activity and inactivity data for the one or more subjects, and collecting and monitoring consciousness pattern data for the one or more subjects;
• a user interface operative to receive control commands, input from a user, for using the control unit to actuate the olfactory dispensing unit to dispense the olfactory agents;
• wherein the olfactory dispensing unit and the control unit are configured to be in electronic communication and wherein the user interface and the control unit are configured to be in electronic communication;
• and
• wherein dispensing of the olfactory agents is configured to modulate the about 24 hour circadian phase of the one or more subjects in response to a condition of the one or more subjects and an environment of the one or more subjects as iteratively measured by the one or more sensors, and thereby align the one or more subjects' about 24 hour circadian phase to the desired schedule.
