Walking interventions increase total sleep time and reduce wake after sleep onset in middle-aged and older adults

A systematic review and meta-analysis of 8 RCTs with 683 participants found that walking interventions increased total sleep time by 34.23 minutes (95% CI: 24.72 to 43.74) and reduced wake after sleep onset by 11.58 minutes (95% CI: -18.50 to -4.66). No significant effects were observed for sleep efficiency, sleep latency, or PSQI total score.

observational

Liu M, Li Y, Ma Y, Zhu Z · Scientific reports (2026)

Participants: N/A
Duration: Not specified in abstract (varies by included RCTs)
Intervention: Walking interventions (various durations and frequencies, with subgroup analysis suggesting sessions ≥30 minutes may be more beneficial)
Outcome: Total sleep time (minutes), wake after sleep onset (minutes), sleep efficiency, sleep latency, Pittsburgh Sleep Quality Index (PSQI) score
Effect Size: MD=34.23 min for total sleep time; MD=-11.58 min for wake after sleep onset
Population: Middle-aged and older adults (mean age not specified in abstract, but typical range 45+ years)

Mechanism Graph

Walking increases physical activity levels
↓
Physical activity promotes circadian rhythm regulation
↓
Exercise reduces stress and anxiety
↓
Result: Improved sleep continuity and duration

Limitations

  • ⚠Substantial heterogeneity observed in PSQI scores, indicating variability across studies
  • ⚠Limited evidence regarding optimal exercise frequency and duration due to small number of studies
  • ⚠Only 8 RCTs included, with a total sample size of 683, limiting generalizability

Frequently Asked Questions

Does walking improve sleep quality in older adults?▼

Walking interventions significantly increased total sleep time by about 34 minutes and reduced time awake after sleep onset by about 12 minutes, but did not significantly improve subjective sleep quality as measured by the PSQI.

How long should walking sessions be to improve sleep?▼

Subgroup analyses suggested that walking sessions lasting 30 minutes or more may be associated with greater sleep-related benefits, though evidence on frequency is limited.

What sleep outcomes were measured in this study?▼

The study measured both subjective sleep quality (PSQI score) and objective outcomes including total sleep time, sleep efficiency, sleep latency, and wake after sleep onset.

Is walking as effective as other exercise for sleep?▼

This meta-analysis focused only on walking interventions; it did not compare walking to other forms of exercise, so relative effectiveness is unknown.
