Biofeedback
HRV Biofeedback Training
HRV biofeedback training is a technique that uses real-time feedback from heart rate variability to teach paced breathing and self-regulation. By breathing at a steady rhythm and observing the body's response, a person can influence autonomic balance and improve control over stress-related arousal. It is used to support relaxation, resilience, and emotional regulation.
