Summary

This field trial is testing whether adjusting sleep schedules can improve symptoms of Shift-Work Disorder (SWD) in active night workers. Over three weeks, participants first follow their usual sleep routines, then transition to structured schedules that vary the timing of sleep—such as morning versus evening sleep periods. Researchers use actigraphy and symptom tracking to measure changes in sleep efficiency, alertness, and overall wellbeing. The trial is registered but has not yet published results.

Why It Matters For Night Shift Workers and Night Owls

Shift-Work Disorder can make it difficult to get restorative sleep and stay alert during work hours. By directly testing different sleep timing strategies in real-world conditions, this study aims to identify schedules that reduce fatigue and improve functioning. For night-shift workers, the results could offer practical guidance on how to adjust sleep windows to better fit demanding schedules.
