HRV & Breathing

Heart rate variability (HRV) is one of the most reliable markers of nervous system health — and it's directly trainable through slow breathing. At around 6 breaths per minute, breathing frequency matches the body's baroreflex loop, producing a resonance effect that maximizes HRV. These articles cover the science, the practice, and what high HRV actually tells us about our physiology.
