Military personnel are at particular risk for circadian rhythm misalignments, partly due to an erratic mission schedule, jetlag from traveling across time zones, and irregular sleep cycles. Studies have shown that these misalignments may affect decision making and psychomotor skills, and have been known to lead to or worsen Post-Traumatic Stress Disorder (PTSD). IAI and the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute are developing a Circadian Rhythm Monitoring and Regulation system (CMR) for soldiers and veterans. The compact, lightweight, and low maintenance CMR includes a wrist-worn device called DaysiWatch. Capable of capturing activity, heart rate, and skin temperature data, DaysiWatch can communicate with emerging connected healthcare devices via Application Program Interfaces (APIs). CMR includes DaysiGoggles, treatment goggles that provide light regulation to filter out and safely deliver circadian effective light as needed with light emitting diode (LED) technology. CMR also has DaysiClipOn, which connects to DaysiGoggles to collect calibrated, ecological lighting data. This ensures that circadian light data is gathered in a manner similar to the human eyes, and with high user-compliance. Finally, CMR communicates with DaysiMeterApp, a cross-platform smartphone application that collects data from all sensors in the system, runs simulations, and provides treatment options in real-time. It automatically controls the circadian lighting needs of users, synchronizes with their calendar, allows them to wirelessly input relevant information, and provides them with treatment options. CMR will be extended for use in the commercial market to help people suffering from insomnia and to maintain a healthy circadian rhythm.
