SleepSight has partnered up with Fitbit

SleepSight is a study that aims to detect relapse in Schizophrenia patients using a Fitbit.

The NIHR BRC-MH Bioinformatics Core has developed a real-time monitoring system in conjunction with CBITS at Northwestern University to track sleep in Schizophrenia patients to detect relapse events. The patients are given a Fitbit Charge HR and a smartphone to monitor sleep and daily activity which is then uploaded to our servers in real-time for evaluation.

Deteriorating sleep quality is one of the major hallmarks of a potential relapse event in Schizophrenia patients. The smaller the time window between data points that we gather, the more insight we gain into the relationship between sleep quality and relapse in Schizophrenia.

While asleep, we tend to move less and are even completely motionless during the REM (rapid eye movement) sleep phase. Furthermore, sleep is accompanied with a significant drop in heart rate, much lower than our normal resting heart rate. Both phenomena can be measured using a Fitbit Charge HR and allow us to quantify how well the participants have slept.

Fitbit Partnership

This is why we partnered up with Fitbit to help us get as much detail as possible. As a Fitbit Partner, we have the ability to “zoom” into our participant’s sleep and detect patterns in the single minute to second spectrum.

We believe that this partnership will allow us to significantly push our research forward and enable us to make more accurate detections and predictions of relapse in Schizophrenia.


The more data we gather, the better! We also need normal control data. Help us by uploading your activity and sleep data to here or forward this link to people you know are wearing activity monitors.
