Personal coherence is a psychophysiological coherence, where there is a synchronization between physical, mental, and emotional systems. Heart rhythm patterns can measure this coherence. The more coherent the heart rhythm pattern – represented by a smooth sinus pattern – the greater the degree of coherence. Heart coherence is defined in HRV (heart rate variability, which reflects the interval between heartbeats). In a state of personal coherence, stress decreases, energy levels rise, and the brain and our heart-brain work together optimally. The brain is in a state of optimal clarity, perception, and performance.
Social coherence occurs when there is a degree of coherence between different people. This can be a couple, but also a group of people. You then notice that you are ‘together on the same frequency within a social setting.’ The communication runs smoothly, together you feel powerful, harmonious, and effective.
Global coherence is the name for global coherence, which refers to the larger community’s mental, physical, emotional, and spiritual well-being. People live in harmony with their hearts, each other, and society. HeartMath Institute believes that global coherence is highly achievable when many people focus their heart intention on a common goal.
