Meditation-based interventions improve subjective sleep quality in older adults with mild cognitive impairment
A systematic review and meta-analysis of 7 studies (n=434) found that meditation-based interventions significantly improved sleep quality in adults aged ≥55 with mild cognitive impairment. The pooled effect size was large (Hedges' g = -0.75, 95% CI -1.23 to -0.28) with substantial heterogeneity (I² = 77.9%). Five of seven studies showed significant improvements in subjective sleep quality, and one actigraphy-based study reported reduced daytime napping.

The Claim
Meditation-based interventions improve subjective sleep quality in older adults with mild cognitive impairment
This conclusion is most relevant to: Adults aged ≥55 years with mild cognitive impairment (MCI).
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸The effects of meditation-based interventions on sleep quality among adults aged ≥ 55 with mild cognitive impairment: A systematic review and meta-analysis. (Geriatric nursing (New York, N.Y.), 2026) —
How It Works
The proposed biological pathway:
- ▸Meditation reduces stress and anxiety, which are common contributors to sleep disturbances
- ▸Improved emotional regulation and reduced hyperarousal may facilitate sleep onset and maintenance
- ▸Enhanced mindfulness may improve sleep-related behaviors and reduce rumination
- ▸Result: Improved subjective sleep quality and psychological well-being
Who Might Benefit
Evidence fit by population:
- ▸Adults aged ≥55 years with mild cognitive impairment (MCI)
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Substantial heterogeneity (I² = 77.9%) across studies, indicating variability in interventions and populations
- ▸Limited number of studies (n=7) and small sample sizes, with only one study using objective actigraphy
- ▸Potential risk of bias in included studies, and lack of standardized protocols across interventions
Frequently Asked Questions
What is the effect size of meditation-based interventions on sleep quality in older adults with MCI?▼
The meta-analysis found a large effect size (Hedges' g = -0.75) indicating significant improvement in sleep quality, though with substantial heterogeneity.
How long do meditation-based interventions need to be to improve sleep?▼
Interventions in the reviewed studies lasted between 4 and 12 weeks, and most showed significant improvements in subjective sleep quality.
Are meditation-based interventions safe for older adults with MCI?▼
The review suggests they are promising non-pharmacological strategies, but caution is warranted due to limited and heterogeneous evidence. No adverse effects were reported in the abstract.
What types of meditation were included in the review?▼
The review included mindfulness, mantra, sound meditation, and hybrid programs.
