Physical exercise improves sleep quality in patients with psychiatric disorders.

A systematic review and meta-analysis of 21 RCTs (1628 participants) found that physical exercise significantly improves sleep quality in patients with psychiatric disorders, with a moderate overall effect size (g = -0.57, 95% CI: -0.75 to -0.38, P < 0.001). Larger effects were observed for aerobic modalities (g = -0.69), low-to-moderate intensity (g = -0.70), and frequency of ≥3 sessions per week (g = -0.60).

Wang M, Su L, Hao L, Song X, Ma J, Guo J, He B, Hu M, Wang R, Feng Y · BMC psychiatry (2026)

Participants: N/A
Duration: Varied across studies (subgroup analysis: <12 weeks showed larger effects)
Intervention: Physical exercise interventions (various types, frequencies, intensities, and durations) compared to control conditions.
Outcome: Sleep quality (measured via validated instruments, e.g., PSQI or similar, reported as Hedges' g).
Effect Size: g = -0.57 (95% CI: -0.75 to -0.38)
Population: Patients diagnosed with psychiatric disorders (e.g., depression, anxiety, schizophrenia) from 21 RCTs (1628 participants).

Mechanism Graph

Exercise reduces hyperarousal and stress hormones (e.g., cortisol).
↓
Exercise promotes circadian rhythm regulation and body temperature changes.
↓
Exercise increases endorphin and serotonin levels, improving mood and relaxation.
↓
Result: Improved sleep quality (reduced sleep latency, fewer disturbances, better efficiency).

Limitations

  • ⚠Univariate meta-regression showed no significant linear moderating effects of intervention duration, frequency, volume, or total weekly exercise time on sleep quality (all P > 0.05), suggesting potential nonlinear or confounded relationships.
  • ⚠The analysis is based on abstract-level data only; full study heterogeneity and risk of bias details are not fully assessed here.

Frequently Asked Questions

What type of exercise is most effective for improving sleep in psychiatric patients?▼

Aerobic exercise modalities showed the largest effect size (g = -0.69) compared to other types.

How often should patients exercise to see sleep benefits?▼

A frequency of ≥3 sessions per week was associated with larger improvements in sleep quality (g = -0.60).

Is exercise intensity important for sleep improvement?▼

Yes, low-to-moderate intensity exercise yielded a larger effect (g = -0.70) than higher intensities.

How long does the exercise intervention need to be to improve sleep?▼

Interventions lasting less than 12 weeks showed larger effects (g = -0.58), but benefits were still present for longer durations.
