Background: Little is recognized about factors affecting poor sleep hygiene and relations of sleep problems with the quality of life among adults. Aims: To evaluate sleep hygiene, explore its associated factors, assess the prevalence of excessive daytime sleepiness (EDS) and insomnia, and their relations with sleep hygiene. Besides, correlate sleep problems with life quality. Methods: A representative sample of primary healthcare population was surveyed using questionnaires comprising sociodemographic characters, personal lifestyles, validated Arabic versions of Epworth sleepiness scales, Athens insomnia scale, short-form health survey questionnaire (SF-12), and developed Arabic sleep hygiene index (SHI). Results: A total of 401 adults participated in the study. The average SHI score was 17.25 ± 7.33. Poorer sleep hygiene was significantly detected in younger age, unmarried, unemployed, smokers, and energy drinks consumers (P < 0.05). Positive significant correlations were correlated with cellphone and video-gaming duration. About 56.61% and 39.90% of participants suffered insomnia symptoms and EDS, respectively. Significant poorer SHI was detected among insomnia and EDS sufferers. Negative significant correlations were observed between scores of both components of SF-12 and EDS, insomnia, and SHI. Conclusion: Significant negative associations were detected between SHI, EDS, insomnia, and both components of life quality. The role of sleep hygiene education programs in the promotion of sleep and quality of life need to be considered.
