Higher average levels of pre-sleep cognitive arousal, rumination, and anticipatory stress are associated with poorer sleep quality and shorter sleep duration in emerging adults
In a 7-day smartphone-based diary study of 166 emerging adults (mean age 20.36 years, 80.1% female), higher between-person average levels of pre-sleep cognitive arousal, rumination, and anticipatory stress were associated with poorer sleep quality and shorter sleep duration. No significant associations were found for sleep onset latency, and within-person day-to-day variations in these cognitive processes were not related to next-morning sleep outcomes.

Higher average levels of pre-sleep cognitive arousal, rumination, and anticipatory stress are associated with poorer sleep quality and shorter sleep duration in emerging adults The current body of evidence comprises 1 study. EvidenceHub rates the overall confidence at 32/100 (low).
The Claim
Higher average levels of pre-sleep cognitive arousal, rumination, and anticipatory stress are associated with poorer sleep quality and shorter sleep duration in emerging adults
This conclusion is most relevant to: 166 emerging adults (mean age 20.36 years, 80.1% female).
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Understanding poor sleep in emerging adulthood: the role of pre-sleep cognitive processes in daily life. (Sleep advances : a journal of the Sleep Research Society, 2026) —
How It Works
The proposed biological pathway:
- ▸Pre-sleep cognitive processes (arousal, rumination, anticipatory stress) are measured as stable individual differences
- ▸These processes are hypothesized to impair sleep via cognitive hyperarousal
- ▸Between-person differences in these processes are linked to sleep quality and duration
- ▸Result: Stable individual differences, not nightly fluctuations, predict poorer sleep
Who Might Benefit
Evidence fit by population:
- ▸166 emerging adults (mean age 20.36 years, 80.1% female)
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Self-reported sleep outcomes may be subject to recall bias
- ▸Sample predominantly female (80.1%) and limited to emerging adults, reducing generalizability
- ▸Observational design cannot establish causality
Frequently Asked Questions
What pre-sleep cognitive processes were studied?▼
The study examined cognitive arousal, rumination, and anticipatory stress reported each evening before sleep.
Did nightly changes in these processes affect sleep?▼
No, within-person day-to-day variations in pre-sleep cognitive processes were not related to next-morning sleep outcomes.
What sleep outcomes were measured?▼
Sleep quality, sleep duration, and sleep onset latency were assessed each morning via smartphone surveys.
Who was the study population?▼
The sample consisted of 166 emerging adults with a mean age of 20.36 years, 80.1% female.
