Summary

Poor sleep is closely related to circadian misalignment; shift workers often experience shift work disorder characterized by excessive sleepiness and recurrent shift work schedules-associated insomnia. This study aims to examine the effects of a program of chronobiology-guided lifestyle interventions (CGLI) on insomnia severity, cognitive performance (psychomotor vigilance and processing speed), and sleepiness in female nurses undertaking rotating-shift work.

Detailed description

This study will use a parallel-group, randomized, assessor-blind, wait-list controlled design to determine the effects of a program of multimodal lifestyle interventions based on chronobiology, consisting of timed bright light exposure, meal timing manipulations, and sleep hygiene education on insomnia severity, cognitive performance (psychomotor vigilance and processing speed), and sleepiness in female nurses undertaking rotating-shift work.
