The activity of the Sun in interaction with the earth's magnetic field causes significant changes in human perspectives, moods, emotions and behavioral patterns.

Dr. Neil cherry, associate Professor of environmental hygiene at Lincoln University, wrote in his scientific work that

Currently there is no known and credible biophysical
mechanism to link the S-GMA with these effects...

a plausible biophysical mechanism for linking S-GMA levels
to biological effects on human health.
