Abstract
Cognitive arousal is central to models of sleep disturbance and insomnia, but findings
remain mixed regarding whether cognitive arousal is associated with objective sleep
disturbance and physiologic hyperarousal. This study explored associations of objective
nocturnal wakefulness and indicators of physiologic hyperarousal with cognitive arousal
in healthy sleepers and individuals with insomnia.
