A meta-analysis of ten randomized controlled trials found that mindfulness-based stress reduction (MBSR) modestly improved self-reported sleep quality in cancer survivors compared with usual care (standardized mean difference -0.29). However, MBSR did not improve objective sleep parameters measured by sleep diaries, polysomnography, or actigraphy. Results against active control conditions were mixed for sleep quality and negative for sleep parameters. The authors conclude that MBSR may help cancer survivors improve sleep quality, but the evidence is inconclusive due to few studies and inconsistent results.
