BACKGROUND: The association between poor sleep hygiene and insomnia symptoms is well known. However, comprehensive investigations of sleep hygiene characteristics in chronic insomnia are limited. This study investigated the poor sleep hygiene characteristics of individuals with chronic insomnia.
METHODS: Data were collected from 2895 adult participants, of whom 300 (10.4%) met the criteria for chronic insomnia. The presence of chronic insomnia was determined using a combination of authorized insomnia screening scales and the international diagnostic criteria for chronic insomnia disorder. Sleep hygiene was assessed using the Sleep Hygiene Practice Scale across four domains: arousal-related behavior, sleep schedule and timing, eating/drinking behavior, and sleep environment.
RESULTS: All sleep hygiene domains were significantly associated with chronic insomnia (odds ratios = 1.08-1.19). The area under the curve (AUC) was acceptable for the arousal-related behavior domain (AUC = 0.824) and the sleep schedule and timing domain (AUC = 0.720), but was not acceptable for the other domains (AUCs = 0.612-0.678). The most common poor sleep hygiene habits in chronic insomnia were lack of regular exercise (55%), lack of exposure to natural daylight during the day (36%), and inconsistent sleep schedules (28-38%). On the other hand, the frequency of problems related to caffeine (26%) and alcohol (11%) was relatively low.
CONCLUSION: When providing sleep hygiene education for chronic insomnia, it may be more helpful to identify patient-specific issues and focus on those, rather than attempting to address every possible topic.
