Watching television relaxes you. The almost undetectable screen flicker is a perfect
mechanism for lowering our brain waves into the alpha state, the condition we are
going for when we meditate. This is why it is so effective for calming an agitated or
over-stimulated kid. It is so effective that even those who watch very little TV, and
are therefore "unconditioned," are put into that state in 3 minutes or less. It's why
so many parents, over decades now, have used "TV time" as a euphemism for
"peace and quiet."
But as we all know, there's a price to pay for this shortcut to deep relaxation, just
as there is with every shortcut ever devised. We all already know about the
opportunity cost of watching TV, all that time spent sitting indoors instead of being
outside getting exercise, which has led in an almost straight line to an epidemic of
obesity and diabetes. And most of us are pretty attuned to the fact that advertisers
are using the highest powered persuasive techniques ever devised to brainwash our
children, and take measures to counteract that. But I"m surprised at how many
parents are dismissive about what TV does to our brains.
When people watch more than a half hour or so of television at a stretch, they go
beyond the meditative state and fall into what is popularly called a stupor. The
longer they watch, the deeper the stupor. When the set is finally shut off, they are
hung over. It's a real hang over, not a figurative one, not a metaphorical one, but
one every bit as real as the kind one gets from drinking too much alcohol. We've all
experienced how surly and out-of-sorts children are after a marathon of TV -- that's
the hang over.
In college (30+ years ago) we were already talking in our journalism classes about
the narcotizing effects of television. It's a real thing. I'm not saying that you should
keep your child away from TV, but you need to know, it's no different than putting
them on drugs. It's an effective, but not a harmless way to buy yourself a little
peace and quiet.
So what exactly does happen to our children's brains as they watch TV?
For one thing, from almost the moment the pictures start to flicker, brain activity
shifts from the left side of our brains (the part of our brains responsible for logical
analysis and critical thought) to the right side. This means that there is little or no
critical analysis taking place, opening their brains to a suggestible, hypnotic state.
When we say that watching television it's a "passive activity," it is true in a very real
sense: scientists detect almost no beta waves at all in TV viewers, indicated no
active involvement in or response to what we are watching.
TV is a physical addiction. It causes the brain to release those feel-good chemicals
called endorphins, morphine like substances created from within the body, and like
all opiates, endorphins are highly addictive.
When you watch television your higher brain regions (like the mid-brain and the
neo-cortex) simply shut down, leaving you with what is sometimes referred to as
the reptilian brain. Studies show that over use of this fight-or-flight part of our
brain leads to atrophy of the parts of our brain used for higher functions making us,
to use the technical term, stupider.
Our brains, like our muscles, need to be "exercised" in order to remain healthy. The
more one watches TV, the less exercise our brains get. Just as lack of physical
exercise is known to lead to countless health issues as we get older, lack of mental
exercise has been linked to an increased likelihood of being diagnosed with ADHD
and other attention disorders, as well as dementia and Alzheimer’s later in life. (Not
to mention the physical risks of heart disease, stroke, and cancer that result from
too much sedentary time in front of the boob tube.)
And like with the use of drugs and alcohol, this narcotic of television is particularly
dangerous when consumed by children given that their brains are not fully
developed.
I know, what a bummer on a summer Saturday, but you know what? It's summer!
It's Saturday! Get outside and play! Studies also show that children who play
outdoors laugh 20 times more than their indoor, TV watching counterparts, and
that's got to be better than quiet time.
