Meditation and Blood Pressure

Meditation and Blood Pressure refers to clinical research on the antihypertensive effects of contemplative practices.

Summary

Multiple randomized trials and meta-analyses have assessed whether meditation techniques — particularly transcendental meditation, mindfulness, andpranayama-based practices — lower blood pressure.

Key Findings

Meta-analyses report modest systolic and diastolic reductions (approximately 4–5 mmHg systolic) compared to controls. Transcendental meditation has the most consistent evidence. Effects are comparable to first-line lifestyle interventions but insufficient as standalone treatment for moderate-to-severe hypertension.

Methodology

RCTs typically last 8–16 weeks with ambulatory blood pressure monitoring as the primary outcome. Controls include health education, muscle relaxation, and waitlist conditions.

Limitations

Publication bias, high heterogeneity across meditation types, and poor adherence to home practice complicate interpretation. Most trials lack long-term follow-up beyond 6 months.

Verification Notes

• ACC/AHA guidelines acknowledge meditation as a adjunctive lifestyle intervention.
• Meta-analyses by Rainforth et al. (2007) and subsequent updates reviewed.
