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?

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
All the participants will have all three intervention periods with washout periods in between. During every intervention week, participants will fill out a quick nightly log about their sleep and what tech they used (smartphone, tablet, or a laptop/computer). During sleep, they will wear a comfy EEG headband measuring their sleep stages.
Because everyone eventually does all three conditions, the investigators can compare each person's own results and get more precise answers with fewer people.
The investigators will analyze the data and perform a statistical analysis. The study will be reported in the manuscript and published in a reputable journal.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Calming Digital Content
Participants will watch calming digital content - specifically, nature documentaries narrated by Sir David Attenborough - for 30 to 60 minutes within one hour before bedtime. Sleep outcomes will be assessed using EEG recordings and subjective sleep quality logs.
Calming digital content
Participants watch a curated selection of soothing documentaries narrated by Sir David Attenborough for 30-60 minutes each evening during one hour before bedtime.
Exciting Digital Content
Participants will engage with exciting digital content by playing the word-based game Ruzzle for 30 to 60 minutes within one hour before bedtime. Sleep outcomes will be evaluated using EEG measurements and subjective sleep assessments.
Exciting Digital Content
Participants engage with the interactive word-based game Ruzzle for 30-60 minutes each evening during one hour before bedtime, designed to provide mental stimulation.
Non-Digital Pre-Sleep Activity
Participants will engage in a non-digital activity by reading a physical, non-fiction book of their choice for 30 to 60 minutes within one hour before bedtime. No digital screens will be used. Sleep outcomes will be monitored via EEG data and self-reported sleep quality measures.
Non-digital book reading
Participants read a non-fiction book of their choice for the same duration, avoiding all digital screens during one hour before bedtime before bedtime.
