Bringing the effects of relaxation

Bringing the effects of relaxation into our minds, television actually disturbs human brain and makes it tired even within the first minutes of TV watching session. Recent researches discovered that television slows down our thinking. Also, image and color flickering affects human vision and, especially, functioning of heart, because the frequencies of such flickering can correspond to the frequencies of the heartbeat or to some electrical frequencies, which support functioning of human heart and brain. Resonance of such frequencies is especially dangerous for a human organism.
