Television programming & effective frequency

Leave a comment

Studies have found that television induces alpha waves in the human brain. Alpha waves are brain waves between 8 and 12 Hertz and are commonly associated with relaxed, meditative states of the brain as well as high suggestibility.

While alpha waves induced through meditation are beneficial (promoting relaxation and understanding), prolonged exposure to the alpha wave state through television can trigger uncoordinated fantasies and an inability to concentrate.
