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.

Tai Chi/Qigong, yoga, and combined exercise improve sleep quality in individuals with breast cancer The current body of evidence comprises 1 study and 1 meta-analysis. EvidenceHub rates the overall confidence at 49/100 (low).
The Claim
Tai Chi/Qigong, yoga, and combined exercise improve sleep quality in individuals with breast cancer
This conclusion is most relevant to: Individuals with breast cancer (4066 participants across 39 RCTs).
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Comparative and Dose-Response Effects of Exercise Modalities on Sleep Quality in Individuals With Breast Cancer: A Bayesian Network Meta-Analysis. (Psycho-oncology, 2026) —
How It Works
The proposed biological pathway:
- ▸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
Who Might Benefit
Evidence fit by population:
- ▸Individuals with breast cancer (4066 participants across 39 RCTs)
Recommended Dose
Approximately 4.5 METs, 281.3 MET·min/session, 910 MET·min/week
Limitations & Caveats
Important context when interpreting this evidence:
- ▸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.
