Introduction: Sleep is a fundamental function shared by all living organisms. Nevertheless, in recent times, there has been a concerning increase in sleep deprivation. Sleep disruptions are linked to an elevated risk of various health issues, which can significantly impact both social and occupational aspects of life. Occupational therapists are well-suited for addressing this issue due to their comprehensive approach. They are uniquely positioned to recognize the diverse factors that impact the quality of sleep, sleep patterns, and daily functioning. Purpose: The purpose of this thesis is to review the literature on occupational therapy interventions in the occupational domain of sleep and rest. Methods: a general literature review was conducted between thesis. Literature was searched between January and February 2023 in the following databases: CINAHL, Web of Science, ProQuest, OT Seeker, and PubMed. The following keywords were used in the search: occupational therapy and insomnia. The final analysis included full-text English-language articles that exceeded a relevance score of 4-relevant. Results: Four main themes and four sub-themes were developed: the importance of sleep and the consequences of insomnia from an occupational therapy perspective, the presence of DT in the field of sleep and rest, the models and assessments used (Sub-themes: models, assessment), and occupational therapy interventions (Sub-themes: correlation between perso and occupation and correlation between environment and occupation). Discussion and conclusion: Sleep itself plays a key role on daily performance, activities, and occupations. It also has a major impact on overall well-being, physically, mentally, and emotionally. The occupational therapy profession, however, has little presence in this area, despite its unique expertise. This is largely due to a lack of knowledge in the field of sleep and rest. We have found that the Canadian Model of Occupational Performance and Engagement and the Person-Environment-Occupation-Performance Model are the most commonly used in this field. However, there are no specific standardised assessments for this domain and there is a great need for their development. Occupational therapist focus on introducing lifestyle changes that reduce the impact of bodily functions on sleep, promoting an environment conducive for better sleep and restructuring daily activities. They also have the knowledge and skills to assess personal and environmental factors that affect sleep. This puts them in an excellent position to strengthen their role in the field of sleep and sleep problems.
