Definitions
Learn the terminology
- Heart Rate Variability (HRV)The variation in time between consecutive heartbeats. Higher HRV typically indicates a more resilient autonomic nervous system.
- BiofeedbackUsing real-time physiological data (HRV, EEG, breathing) to train conscious control over involuntary processes.
- Vagus Nerve StimulationElectrically stimulating the vagus nerve through the skin to influence stress, anxiety, and sleep — emerging clinical category.
- CoherenceA state of harmony between heart rhythm, breathing, and brainwaves — trained via biofeedback for stress regulation.
