As discussed in previous commentaries, the solar activity affects the Earth’s magnetic field. Some science is starting to emerge that demonstrates a possible connection between solar activity and Earth events like earthquakes, volcanoes, hurricanes, floods and storms.
Not only is the Earth’s magnetic field affected by the solar activity, so is human health and behavior. Some of the scientific findings are discussed in more detail below.
The electrical currents from the sun also affect the human body’s magnetic field.
The environmental scientist Neil Cherry (2001) reviewed a large number of studies that identified significant physical, biological and health effects that are associated with changes in Solar and Geomagnetic Activity (S-GMA). He suggested that the Schumann Resonances (SR) frequencies that link solar and geomagnetic activity are what link solar activity to the effects on human health and behavior. The SR have ultra low frequency peaks at 7.8Hz, 14, 20, 26, 33, 39, 45, and 51 Hz, which closely overlap with the human brain (also see GCI commentary July 15, 2009)…
