LiveScience.com reports that daydreaming is a healthy and normal use of the brain. According to the study:
Until now, scientists had thought that the brain’s “default network,” which is linked to easy, routine mental activity, was the only part of the brain that remains active when the mind wanders. But in the study subjects, the brain’s “executive network” – associated with high-level, complex problem-solving – also lit up. The less subjects were aware that their mind was wandering, the more both networks were activated. “This study shows our brains are very active when we daydream – much more active than when we focus on routine tasks,” Christoff said.
So I guess (some of our) parents were wrong. Dream away!
“All the leaves are brown
and the sky is grey,
I’ve been for a walk
on a winter’s day.
I’d be safe and warm
if I was in L.A.
on such a winter’s day.”
