Polysomnographic Determinants of Self-Perceived Sleep Quality at Night and During the Daytime Between Consecutive Night Shifts

Introduction: Shift work and its associated disruption of the body clock can substantially impair the quality of sleep. Impaired sleep quality can influence both physical and mental health and well-being. As such satisfaction with sleep is an important aspect of shift workers' quality of life. However, it is not clear to what extent perceptions of daytime and night-time sleep quality are similarly informed by its structural composition. The aim of this study is to identify the features of sleep that are most important for satisfaction with night-time and daytime sleep quality so that individuals may better evaluate their own sleep and how it might be improved.
