HRV Coherence Biofeedback Technology
Based on over 33 years of research at HeartMath Institute, our emWave® and Inner Balance™ devices provide real-time heart rate variability (HRV) coherence feedback—showing you exactly when your heart rhythm shifts from stressed to calm, so you can train yourself to maintain that coherent state.
Why Heart Coherence Training is so Effective
Using HeartMath’s HRV biofeedback technology for just 5 minutes a day helps you reduce stress, make better decisions, and improve your interactions with others. Many users say they feel calmer and more centered throughout the day. The technology measures and displays your heart rhythm pattern in real time, revealing how your emotions are affecting your nervous system—strengthening the connection between your heart and brain for better thinking, emotional control, and performance.
Observe your heart rhythm (HRV) which reflects your level of inner balance and your emotional state.
Use scientifically validated techniques to guide you to a state of higher Coherence.
Real-time Coherence feedback confirms when you’ve made the shift and trains you to sustain it.
