Summary
This paper examines the effects of Light-at-night (LAN) exposure in the sleeping environment on sleep, circadian rhythmicity, attention bias, and psychological health, finding that those who perceive LAN are more likely to report that these sources are disruptive to their sleep and are associated with poor sleep quality and psychological health.
Categories
Sleep and insomnia: The paper investigates the impact of Light-at-night (LAN) exposure on sleep quality and timing, finding that those who perceive LAN in their sleeping environment are more likely to report disrupted sleep.
Alertness and performance: The paper explores the association between LAN exposure and attention bias, though it finds no significant effect of the perception of LAN in the sleeping environment on attention bias towards sleep-related word stimuli or towards images depicting LAN sleep environments.
Cognitive function and memory: The paper discusses the role of the circadian clock in cognitive function, though it does not directly investigate the impact of LAN exposure on cognitive function and memory.
Mood regulation: The paper finds that the subjective perception of external LAN is associated with poor psychological health, suggesting a potential impact on mood regulation.
Lighting Design Considerations: The paper's findings on the disruptive effects of LAN exposure in the sleeping environment have implications for lighting design in residential settings.
