To systematically map research hotspots and evolutionary trajectories in the relationship between physical activity and insomnia, addressing the current lack of comprehensive analysis in this domain.
Approach:
Key Findings:
Annual growth rate of publications reached 15.12%.
The United States and China were the leading contributors.
High-impact institutions included Harvard University and the University of California system.
Thematic evolution revealed a shift from metabolic associations to genetic causality and digital interventions.
Interpretation:
The PA-insomnia research field has transitioned from validating metabolic associations to exploring genetic causalities and digital interventions, emphasizing multidisciplinary integration and digital transformation.
Limitations:
The study is limited to English-language publications.
Analysis is confined to two databases, potentially missing relevant studies.
Conclusion:
Future research may focus on AI-enabled wearable systems for sleep monitoring and integrating multi-component interventions into clinical guidelines to address escalating sleep health challenges.
