Heart-Rate Variability (HRV) Training

Evidence grade: Context Dependent

Illustration for Heart-Rate Variability (HRV) Training

A biofeedback-based breathing technique that teaches users to breathe at their personal resonance frequency (usually ~6 breaths/min) to maximize HRV and autonomic flexibility.

How to practice Heart-Rate Variability (HRV) Training

Use an HRV biofeedback app or device to identify your optimal breathing rate (~5.5–6.5 breaths/min). Practice 10–20 minutes daily or during stress. Focus on smooth, slow inhalations and extended exhalations. Combine with mindfulness or light movement for greater transfer to daily life.

The evidence behind Heart-Rate Variability (HRV) Training

HRV is a key marker of stress resilience and vagal tone. Controlled studies show HRV training improves emotional regulation, blood pressure, and recovery from stress. Mechanistically, resonance-frequency breathing synchronizes baroreflex and vagal feedback, optimizing prefrontal–autonomic coupling. Evidence strong for stress and anxiety, moderate for cognitive or aging benefits.
