The institute of Heart Math whose work has been verified in studies conducted by Stanford University among others ,has found that our hearts generate an electromagnetic field around us that is several feet in diameter and five thousand times greater then the field generated by the brain.
This is no surprise to me or to you either I'm sure as it just confirms the expansion we've all experienced in the presence of an open warm, loving heart and the contraction felt in an atmosphere of fear.
One measure of your hearts' activity that reflects your emotional state is called heart rate variability, which shows variations in the intervals between heartbeats.In Studies researchers have found that people's heart patterns look different when they're happy then when they are angry,frustrated or sad.

Negative emotions cause erratic patterns called heart rhythm incoherence which has a damaging effect on the body. Feeling angry,frustrated or sad leads to the release of stress hormones and cholesterol into the body.Your heart pumps faster and your blood pressure rises. In contrast feelings of appreciation and love create heart rhythm coherence ie smooth even patterns in the heart rhythm's. According to research heart rhythm coherence increases production of good hormones, normalises blood pressure, improves cognitive functions and strengthens the immune system.
