Evening Screen Content and Sleep Architecture in Older Adults: Crossover RCT
Sponsor: Blekinge Institute of Technology
Summary
Title The Effect of Evening Technology Use with Calming vs. Exciting Content on Sleep Architecture in Older Adults: A Crossover Randomized Controlled Trial Background The study explores how evening use of digital devices with different types of content (calming vs. exciting) affects sleep in older adults. While technology's effects on sleep have been studied in younger populations, its specific impacts on older adults remain under-researched. This study fills that gap by focusing on subjective and objective sleep measures. Objectives and Research Questions Objective: Compare the effects of calming digital content, exciting digital content, and non-digital activities on sleep architecture. Key Questions: How does content type impact sleep architecture and quality? Does calming content lead to better sleep outcomes than exciting content? Are there subjective differences in sleep quality across conditions?
