Night Shift Owl (in development)


Night Shift Owl helps synchronise your body clock to reduce fatigue and improve sleep.


People who work night shifts are less alert, have poorer sleep, and make more errors at work. This happens, in part, because their body clock is out of sync with the work environment.

How does it work?

To help synchronise your body clock to your work schedule:

  1. Enter your work schedule and sleep pattern on the plan page.
  2. Get and follow your own personalised fatigue-reduction plan.
  3. Have a good night shift.

What does the research show?

Most people who work night shifts do not fully adapt to their work schedules. Their body clock remains out of sync with their environment, similar to being jet lagged. The body clock is determined by circadian rhythms — daily physiological patterns of mood, sleep, and alertness. For example, people are usually most tired between 2:00 AM and 5:00 AM. Human error at that time may be partly responsible for some notorious workplace disasters, such as the nuclear accident at Chernobyl (Mitler et al., 1988).

Fortunately, studies show that bright light exposure, such as sunlight, can help align your body clock to the night shift (Smith & Eastman, 2012). Getting bright light exposure in the evening will increase alertness during night shifts and improve sleep afterwards. These kinds of interventions have been tested on nurses, police officers, industrial workers, and astronauts.
