Impact of Standalone Digital Mindfulness Interventions on Adult Sleep Quality
Overview
This meta-analysis of 18 RCTs involving 4870 adults found that standalone digital mindfulness-based interventions (DMBIs) moderately improve sleep quality and mental health. Despite very low-certainty evidence due to heterogeneity and publication bias, a dose-response relationship was observed, supporting DMBIs as scalable, cost-effective tools for sleep health.
Background
Sleep disturbances are a growing global health concern, worsened by the COVID-19 pandemic and increased digital media use. Traditional pharmacological treatments pose risks, and cognitive behavioral therapy for insomnia often suffers from poor adherence. Mindfulness-based interventions (MBIs) have shown promise in improving sleep by reducing hyperarousal and rumination. Digital delivery of MBIs (DMBIs) offers increased accessibility but their independent effects on sleep and mental health have not been rigorously isolated until now.

Key Findings
Standalone DMBIs significantly improved sleep quality with a moderate effect size (Hedges’ g = 0.38, p < 0.001).
Mental health outcomes also improved moderately (Hedges’ g = 0.33, p < 0.01) following DMBIs.
Sensitivity analyses confirmed the robustness of these findings despite high heterogeneity.
Meta-regression revealed a dose-response relationship between intervention dose and outcome improvements.
High heterogeneity and publication bias lowered the certainty of evidence to very low.
Included studies spanned diverse adult populations, both clinical and non-clinical, with sample sizes ranging from 14 to 1255 participants.
Clinical Implications
Standalone digital mindfulness interventions represent a promising, scalable, and cost-effective approach to improve sleep quality and mental health in adults. Clinicians may consider recommending DMBIs as flexible alternatives to pharmacological or traditional behavioral therapies, especially for patients facing adherence challenges. However, further high-quality research is needed to optimize delivery formats and tailor interventions to specific populations.
Conclusion
This comprehensive meta-analysis supports the potential efficacy of standalone DMBIs in enhancing adult sleep quality and mental health, though evidence certainty remains very low. Continued rigorous research is essential to confirm these benefits and guide clinical implementation.
