Attributed extracts from the research record
“energetic environmental phenomena affect psychophysical processes that can affect people in different ways depending on their sensitivity, health status and capacity for self-regulation.”
“Increase in cosmic rays, solar radio flux, and Schumann resonance power was all associated with increased HRV and parasympathetic activity.”
“daily autonomic nervous system activity responds to changes in geomagnetic and solar activity”
