Nowadays, people can keep negative thoughts at bay with a frenzy of activity. Kate Murphy writes on the consequences in the Sunday Review section of the New York Times.
“You can’t solve or let go of problems if you don’t allow yourself time to think about them. It’s an imperative ignored by our culture, which values doing more than thinking and believes answers are in the palm of your hand rather than in your own head. [...]
Suppressing negative feelings only gives them more power, leading to intrusive thoughts, which makes people get even busier to keep them at bay.
Studies further suggest that not giving yourself time to reflect impairs your ability to empathize with others. “The more in touch with my own feelings and experiences, the richer and more accurate are my guesses of what passes through another person’s mind,” said Giancarlo Dimaggio, a psychiatrist with the Center for Metacognitive Interpersonal Therapy in Rome, who studies the interplay of self-reflection and empathy. “Feeling what you feel is an ability that atrophies if you don’t use it.”
Researchers have also found that an idle mind is a crucible of creativity. A number of studies have shown that people tend to come up with more novel uses for objects if they are first given an easy task that allows their minds to wander, rather than a more demanding one.”
