There is a dynamic and reciprocal relationship between stress and emotions. Coherence is the state where bodily systems are integrated and operating at optimal levels.
Heart rhythms are particularly sensitive to changes in emotional state. Heart health is reflected in variability in heart rate. The analysis of heart rhythms or heart
rate variability is recognized as a measure that reflects heart-brain interactions and autonomic nervous system dynamics. The heart is considered to be in coherence when
there is a healthy change in heart rate. HeartMath is a biofeedback program designed to teach physiological coherence where the body is more in sync and aligned. As a
result, there is a gain in clarity, calmness, focus, and control of emotions.
