Global Research Landscape of Sleep Health in Nursing: A Bibliometric and Visualization Study

This research intends to provide a comprehensive review of existing literature on sleep within the nursing field, employing bibliometric methods. A comprehensive analysis of the available literature concerning sleep in nursing was carried out through the Web of Science Core Collection (WoSCC) on October 20, 2025. The search terms "sleep" and "nursing" played a crucial role in identifying relevant research studies. VOSviewer was applied for bibliometric analysis and visualization to identify authors, journals, countries and display the keyword co-occurrence networks. A total of 2.456 publications focused on the topic of sleep were identified from 1991 to 2025. The dataset comprised predominantly research articles (2.296, 93.5%). These publications appeared in a total of 191 distinct academic journals and collectively received 103,025 citations over the analyzed period. The number of publications increased by an average of 6.83 units per year during the observed period (R² = 0.9622; p < 0.001). In the keyword co-occurrence network, "sleep," "sleep quality," and "nursing" keywords the highest frequency. The Journal of Clinical Nursing exhibited the highest publication output with 109 articles. The United States accounted for the largest share of publications. Development and Adaptation of Sleep Instruments in Nursing was performed on 14 measurement tools. This bibliometric study revealed the research points and trends in the field of sleep in nursing research. Future research should aim to strengthen international collaboration among nurse researchers, leveraging artificial intelligence tools and wearable technologies to effectively address sleep-related issues and enhance sleep quality.
