Meditation and Telomere Length

Meditation and Telomere Length refers to research examining whether contemplative practices influence the biological aging marker of telomere attrition.

Summary

Studies investigate whether sustained meditation practice affects telomere length and telomerase activity — biomarkers associated with cellular aging and stress resilience.

Key Findings

Higher telomerase activity has been observed in long-term meditators compared to controls. Intensive retreats (e.g., three-month retreats) show increases in telomerase activity. Cross-sectional studies suggest meditators may have longer telomeres than age-matched non-meditators, though causality remains unestablished.

Methodology

Most studies use cross-sectional designs comparing meditators to controls, with blood samples assayed for telomere length via qPCR or FISH and telomerase via TRAP assay. A few longitudinal studies track participants through retreats.

Limitations

Small sample sizes, self-selection bias among long-term practitioners, and difficulty controlling for lifestyle confounders (diet, exercise, sleep) limit causal inference.
