Abstract The objective of this study was to examine the prevalence of sleep debt, insomnia and long working hours among Finnish IT professionals and to analyse which specific work-related factors are associated with shortened sleep. A total of 2334 IT professionals responded to a questionnaire survey. Thirty-seven per cent reported sleep debt of at least 1h and 6% of at least 2h, while 16% reported insomnia. Twenty-seven per cent worked for a minimum of 50h per week. Hierarchical regression analyses were applied to investigate risk factors of sleep debt and insomnia. The most important factors associated with both sleep debt and insomnia were work-related demands requiring long hours, mental stamina, problem solving and positive perceptions of work, such as job control and importance of the respondents' own work in their life.
