Predicting the impact of work-schedules and lifestyle choices on sleep and alertness.

Mathematical models of sleep-wake and alertness dynamics.

Raster plot of sleep predictions.
An example raster plot of sleep predictions in the context of a schedule of different work shifts and other time commitments during which sleep is not possible. Lighting, included as a background, incorporates a day-night profile as well as fixed lighting on shift.

Features

Predictions

Predicts need for sleep and common measures of alertness based on past history and current context...

Validated

Predictions have been experimentally validated on both laboratory and real-world data...

Time-Zones

Supports time-zone information: proper handling of daylight savings transition; jet-lag; approximate sunrise/sunset times

Lighting

Models adjust to lighting information, with the option the provide specific lighting in addition to a built in day night profile.

Recommendations

Given a schedule, recommends sleep times that optimise either total sleep time or alertness during work shifts.
