  • 1Department of Psychiatry, College of Medicine, Korea University, Seoul, Korea.


PURPOSE: Poor sleep hygiene can complicate any other syndrome producing insomnia complaint and must always be considered in any treatment. In clinical situation, it is important for Insomniacs to practice the sleep hygiene rule in treatment strategies. The authors investigated the recognition of sleep hygiene and the practice of it in general population, then provided the data available for physician to educate the sleep hygiene in treatment of insomnia. METHOD: The 330 subjects were at the age above 18 in Seoul, Korea. The questionnaire included the experience of insomnia and knowledge of caffeine, and 4 categories of sleep hygiene instruction, eg, homeostatic drive far sleep, circadian factors, drug effects, and arousal in sleep sleeper. The interview was done face to face by the investigators.
In general, the knowledge about the drug effects on sleep was relatively poor. The degree of recognition of each item indicating organization of sleep and arousal in sleep setting was various. Poor sleeper showed no difference in recognition of sleep hygiene categories except drug effects on sleep compared to good sleeper, but they practiced sleep hygiene rules poorly in categories of homeostatic drive and arousal in sleep setting, though various by items.
The findings, in which the degree of recognition of the items in 4 sleep hygiene categories was venous, indicated that sleep hygiene education should be done in details by each item. It seems like the poor sleeper practiced sleep hygiene poorly in categories of homeostatic drive and arousal in sleep setting compared to good sleeper. this finding suggested that the efforts, which reflected the behavioral patterns of insomniacs shown in clinical setting to get good sleep, frustrated the practice of sleep hygiene actively.
