Cardiorespiratory Coherence

Meaning

Cardiorespiratory coherence describes a state of optimal physiological function where the heart rate variability (HRV) and the respiratory rhythm synchronize, creating a smooth, sinusoidal pattern in the heart rate. This synchronized state indicates a highly efficient and balanced interaction between the sympathetic and parasympathetic branches of the autonomic nervous system (ANS). Achieving this coherence is clinically associated with reduced stress, improved emotional regulation, and enhanced hormonal balance, particularly concerning the HPA axis. It serves as a quantifiable marker of autonomic nervous system resilience and overall physiological health.
