Bedtime rumination mediates the association between burnout and insomnia in emergency department staff
This study found that cognitive pre-sleep arousal, specifically bedtime rumination, fully mediated the relationship between burnout and insomnia in emergency department staff. Vulnerable shift adaptors, identified by lower-than-expected sleep metrics given their schedule load, reported higher burnout, emotional exhaustion, and insomnia. The findings support a cognitive-behavioral framework linking stress-related cognition to both subjective sleep complaints and objective shift adaptation.

The Claim
Bedtime rumination mediates the association between burnout and insomnia in emergency department staff
This conclusion is most relevant to: 58 physicians and nurses working in emergency departments.
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Bedtime rumination mediates the burnout-insomnia link and relates to shift adaptation in emergency department staff. (Scientific reports, 2026) —
How It Works
The proposed biological pathway:
- ▸Burnout increases cognitive pre-sleep arousal (bedtime rumination)
- ▸Bedtime rumination disrupts sleep initiation and maintenance
- ▸Sleep disruption leads to insomnia symptoms
- ▸Result: Cognitive pre-sleep arousal fully mediates the burnout-insomnia link
Who Might Benefit
Evidence fit by population:
- ▸58 physicians and nurses working in emergency departments
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Small sample size (n=58) limits generalizability
- ▸Cross-sectional mediation analysis cannot establish causality
Frequently Asked Questions
What is bedtime rumination?▼
Bedtime rumination refers to cognitive pre-sleep arousal, such as worrying or thinking about work-related stressors while trying to fall asleep.
How was shift adaptation measured?▼
Shift adaptation was classified using actigraphy-derived total sleep time and sleep regularity, comparing actual sleep metrics to expected values based on schedule-related load.
Did the study test any intervention?▼
No, this was a secondary pre-intervention analysis of the REST randomized controlled trial, meaning no intervention was tested in this analysis.
What population was studied?▼
The study included 58 physicians and nurses working in emergency departments, a group with high prevalence of burnout and sleep disturbances.
