Slow breathing reduces blood pressure: systematic review
Systematic review of 24 RCTs showing slow breathing (6 breaths/min) significantly reduces systolic and diastolic blood pressure in hypertensive patients.
Key Results
- Mean SBP reduction: 4.8 mmHg
- Mean DBP reduction: 2.5 mmHg
- Greater effects with guided device-assisted practice
Mechanism
Slow breathing optimizes baroreflex sensitivity and enhances parasympathetic activity.
Outcomes
- Systolic Blood Pressure-4.8mmHg (Millimetres of Mercury)
- Diastolic Blood Pressure-2.5mmHg (Millimetres of Mercury)
