Maladaptive Sleep Hygiene Practices in Good Sleepers and Patients with Insomnia

Previous studies examining the associations between sleep hygiene practices and insomnia have produced inconsistent results. This study further investigates this issue by examining different domains of sleep hygiene separately. One hundred and six insomnia patients and 89 good sleepers participated in the study. Their sleep hygiene, sleep quality and insomnia severity were assessed with subjective rating scales. Among good sleepers, almost all domains of sleep hygiene correlated significantly with their sleep ratings. However, in insomnia patients, only the arousal-related behavior correlated with sleep ratings. The findings suggest that strategies in prevention and treatment of sleep disturbance may be different accordingly.
