The Science of Heart Rate Variability
Why is an irregular heartbeat healthier?
As highlighted by The Economist, heart-rate variability does not measure how fast your heart beats, but how dynamically flexible the intervals are between individual contractions.
A metronomic, rigid rhythm signals an autonomic system locked in chronic stress or fatigue. In contrast, high beat-to-beat variability (RMSSD) proves the vagus nerve is actively braking and accelerating cardiac pacing in real time to match oxygen, blood pressure, and psychological demands.
