Moderate physical activity is associated with a modest reduction in insomnia risk, while occupational physical activity may increase insomnia risk

This meta-analysis of 27 observational studies found that moderate physical activity was associated with a 7% lower risk of insomnia (OR=0.93, 95% CI 0.87-1.00), while high physical activity showed no significant association (OR=0.96, 95% CI 0.85-1.09). Occupational physical activity was associated with a 21% higher risk of insomnia (OR=1.21, 95% CI 1.02-1.43). The findings suggest that the intensity and domain of physical activity matter for sleep health.

observational

Xie CQ, Xie FF, Cui JH, Kong LJ, Yao F, Fang M · Journal of global health (2026)

Participants: N/A
Duration: N/A
Intervention: Physical activity (various intensities and domains, including leisure-time and occupational)
Outcome: Insomnia symptoms or risk (odds ratio)
Effect Size: OR=0.93 for moderate PA; OR=1.21 for occupational PA
Population: General population (observational studies)

Mechanism Graph

Moderate physical activity may improve sleep through thermoregulation, energy conservation, or stress reduction
↓
Occupational physical activity may involve physical strain, irregular schedules, or psychosocial stress
↓
These factors may differentially affect sleep regulation
↓
Result: Moderate PA reduces insomnia risk, occupational PA increases it

Limitations

  • ⚠Observational study design limits causal inference
  • ⚠Heterogeneity in PA measurement and insomnia definitions across studies
  • ⚠Potential residual confounding (e.g., socioeconomic status, comorbidities)
  • ⚠Publication bias was assessed but not detected, but small-study effects cannot be fully excluded

Frequently Asked Questions

Does high-intensity physical activity reduce insomnia risk?▼

No, high physical activity was not significantly associated with insomnia risk (OR=0.96, 95% CI 0.85-1.09) in this meta-analysis.

What is the effect of moderate physical activity on insomnia?▼

Moderate physical activity was associated with a 7% lower risk of insomnia (OR=0.93, 95% CI 0.87-1.00).

Does occupational physical activity affect sleep?▼

Yes, occupational physical activity was associated with a 21% higher risk of insomnia (OR=1.21, 95% CI 1.02-1.43).

What type of physical activity is recommended for better sleep?▼

The study suggests that moderate leisure-time physical activity may be beneficial, while occupational physical activity may not confer the same benefit and could even increase insomnia risk.
