Heart Coherence Biofeedback is also known as heart-rate variability training. It is a type of biofeedback training that uses heart rate variability (HRV), a measure of the oscillation or variation in the interval between consecutive heart beats. As a marker of physiological resilience and behavioral flexibility, HRV reflects our ability to adapt effectively to stress and environmental demands.

Sens.ai trains us to evoke a smooth, sine-wave-like pattern in the heart rate variability trace. This is called coherence. By accessing coherence we access an optimal state of functioning characterized by increased synchronization and harmony in the body's systems, particularly the heart, brain, and nervous system. When in coherence many people report a significant improvement in emotional stability, mental clarity, and cognitive functioning. Other benefits include reduced stress and anxiety, improved sleep, enhanced resilience and wellbeing and deeper sense of connection to self, others and nature.
