I became interested in the science of this years ago, and believe it or not it was because of the noticeable effect I felt on myself Sunday summer
mornings when my mother would take us to church.
I couldnt understand how I could go from being So freshly awake, to feeling tired so quickly, and I noticed others reacting the same.
Cycles most certainly can be and are generated to subtley control.
There's an entire science around it, ways to detect it, and ways to avoid and employ it.
To briefly answer the Sunday morning church situation, it was the fans, they produced a pure 7 hertz, zoned an open mind right out.
Above 40 Hz is called Gamma, these are waves used to stimulate Higher mental activity, including perception, problem solving, fear, and
13–40 Hz is a Beta wave used to stimulate Active, busy or anxious thinking and active concentration, arousal, cognition
7–13 Hz Alpha is a wave used to stimulate Relaxation (while awake), pre-sleep and pre-wake drowsiness
4–7 Hz Theta is a wave used to stimulate Dreams, deep meditation, REM sleep
< 4 Hz Delta are waves used to stimulate Deep dreamless sleep, loss of body awareness
