Introduction: Sleep represents a fundamental biological need and a basic occupation that significantly influences physical and mental regeneration, as well as daily functioning. Among the student population, sleep quality is often compromised by academic demands, irregular sleep patterns, the use of electronic devices, and other contributing factors. Poor sleep quality can negatively affect academic performance, well-being, and engagement in daily activities. Purpose: This thesis examined how students of the Faculty of Health Sciences in Ljubljana evaluated the quality of their sleep and explored how they connect it with their daily functioning and unhealthy habits, as well as which strategies they use to improve sleep quality. In addition, the study aimed to highlight the role of occupational therapy in supporting healthy sleep. Methods: Data were collected using an online questionnaire developed on the basis of a literature review and existing questionnaires and analyzed using descriptive statistics. The questionnaire was fully completed by 376 students from various study programs. Results: About one-third of the students rated their sleep quality as high. Almost half achieved the recommended sleep duration, and more than half reported experiencing deep sleep. Among students, morning sleepiness, reduced motivation, poor concentration, and daytime fatigue were common. Students assessed that poorer sleep quality was least associated with basic activities and more strongly associated with academic obligations and work. During examination periods, students reported sleeping less, which, in their opinion, was negatively associated with learning and exam preparation. The most common unhealthy habits were the use of electronic devices before bedtime and irregular sleep patterns, while alcohol and caffeine consumption were less common. The strategies used to improve sleep quality included avoiding caffeine and nicotine and sleeping in a dark room, while less frequent strategies were keeping a sleep diary, sleeping without electronic devices, and using relaxation techniques. Discussion and Conclusion: The findings indicate that sleep quality among students is not optimal, as confirmed by their reports of sleep difficulties, their well-being, the presence of unhealthy habits, and the less frequent use of certain strategies to improve its quality. Greater awareness of the importance of sleep and promotion of effective strategies is needed, particularly during periods of high academic demands. Sleep as an occupation deserves more attention at the individual level, within educational programs, and in future research. Occupational therapy plays an important role by applying a holistic approach to recognize inadequate patterns and habits and to develop effective strategies for improving sleep.
