Tai Chi/Qigong, yoga, and combined exercise improve sleep quality in individuals with breast cancer

A Bayesian network meta-analysis of 39 RCTs with 4066 participants found that Tai Chi/Qigong showed the largest sleep benefit (Hedges' g = -0.45, 95% CrI: -0.86 to -0.04), followed by yoga and combined exercise (both g = -0.30) compared to active controls. Dose-response analyses suggested optimal benefits at moderate doses around 4.5 METs, 281.3 MET·min/session, and 910 MET·min/week.

Participants: N/A
Duration: Not specified in abstract
Intervention: Exercise modalities including Tai Chi/Qigong, yoga, combined exercise, aerobic exercise, resistance training, dance, and stretching
Outcome: Sleep quality measured by Pittsburgh Sleep Quality Index (PSQI) or other validated sleep instruments
Effect Size: Hedges' g = -0.45 (Tai Chi/Qigong), -0.30 (yoga and combined exercise)
Population: Individuals with breast cancer (4066 participants across 39 RCTs)

Mechanism Graph

Exercise reduces stress and anxiety through cortisol regulation
↓
Physical activity promotes thermoregulatory cooling and circadian rhythm entrainment
↓
Moderate exercise enhances endorphin release and reduces pain-related sleep disruption
↓
Result: Improved sleep quality scores

Limitations

  • ⚠Very low certainty of evidence due to limited head-to-head comparisons
  • ⚠Potential heterogeneity in exercise protocols and sleep outcome measures across studies

Frequently Asked Questions

Which exercise modality is most effective for sleep in breast cancer patients?▼

Tai Chi/Qigong showed the largest sleep benefit (Hedges' g = -0.45), followed by yoga and combined exercise (both g = -0.30).

What is the optimal exercise dose for improving sleep quality?▼

The analysis suggested moderate doses around 4.5 METs intensity, 281.3 MET·min per session, and 910 MET·min per week.

Is resistance training effective for sleep improvement in breast cancer?▼

Resistance training showed no clear advantage over active controls in this meta-analysis.

How many participants were included in this analysis?▼

The meta-analysis included 39 randomized controlled trials with a total of 4066 participants.
