Summary
Tai Chi/Qigong and yoga show promise for improving sleep quality in breast cancer patients. Moderate exercise doses appear most beneficial, but more research is needed.
Area of Science:
- Oncology
- Exercise Science
- Sleep Medicine
Background:
- Sleep disturbances are common in breast cancer survivors.
- Exercise interventions are explored to improve sleep quality in this population.
Purpose of the Study:
- To compare the efficacy of different exercise modalities for improving sleep quality in breast cancer patients.
- To investigate the dose-response relationship between exercise and sleep improvement.
Main Methods:
- A systematic search of multiple databases was conducted up to March 2026.
- Bayesian multilevel network meta-analysis compared exercise types against active controls.
- Meta-regression and dose-response analyses examined effect modifiers.
Main Results:
- Thirty-nine trials with 4066 participants were analyzed.
- Tai Chi/Qigong, yoga, and combined exercise demonstrated significant sleep benefits compared to active controls.
- Moderate exercise doses showed greater benefits, with specific MET and MET·min/week ranges identified.
Conclusions:
- Tai Chi/Qigong and yoga are promising for enhancing sleep quality in breast cancer patients.
- Optimal exercise benefits may be achieved within a moderate dose range.
- Findings require cautious interpretation due to low evidence certainty; high-quality RCTs are recommended.
