This document discusses the links between solar and geomagnetic activity and human health, behaviors, and physiology. It finds that solar and geomagnetic cycles correlate with societal conflicts and mortality from heart disease. Specifically, it reports that the incidence of myocardial infarction increases by 7% in days following geomagnetic storms. It also discusses daily, weekly, yearly, and multi-year rhythms in heart rate, blood pressure, heart rate variability, depression rates, suicide rates, and acts of crime and terrorism that match rhythms in solar and geomagnetic activity. The document suggests that intentional heart coherence may modulate the geomagnetic field and potentially affect others.
