One of my absolute favourite Cycles Researchers was Alexander Chizhevsky. We have an article about him on CRI, but this one has much more details of his life.
How the Sun Affects our Minds.
It begins…
More than three-quarters of all instances of human unrest—battles, upheavals, riots, revolutions, and wars—occur during the periods of the maximum number of sunspots in the Sun… So powerful is this cosmic zeitgeber that it may even influence our physical size, our longevity, our mental stability, our propensity to violence, and possibly even what we consider our uniquely individual motivation…
One of the most important conclusions is Chizhevsky’s discovery went beyond periodicities and cycles, for he had uncovered a sobering truth about the human condition: we are not completely in charge of our own destiny.
I would go further and say that we are not at all in charge.
Please read the article. My own conclusion about how the Sun affects our minds is as follows:
The solar wind comes past the earth at about 300 to 700 kilometers per second and fluctuates dramatically. This causes the earth’s electromagnetic field to ring like wind chimes in the wind. The natural frequency of the earth’s electromagnetic field is 8 cycles per second, called the Schumann resonance as that is the rate for electromagnetic waves to travel around the earth. That frequency is right in the middle of human brain wave frequencies so we can understand how the sun affects us.
