In response to our different mental states, our brain produces certain Brain Waves, which are Electro chemical.
The Electro Encephalograph (EEG) can record our brain wave activities.
Research has discovered a wide range of brain wave frequencies. They are named as Beta, Alpha, Theta, Delta, and Gamma waves.
When one is under stress – worry, her/his brain produces Beta waves.
The brain becomes more synchronized, balanced when it produces alpha and theta waves.
The mind comes out of obsessive and survival thinking when the brain waves are in the range of alpha and theta.
In addition, it becomes more open, relaxed, holistic and creative.
