Disengagement: Reading is most effective for stress

Target Language or Knowledge:

Your brain can’t operate at maximum capacity 24/7—far from it. We all need periods of disengagement to rest our cognitive capabilities and get back to peak functionality. Tony Schwartz talks about this as one of the most overlooked elements of our lives: Even the fastest racing car can’t win the race with at least one or two great pit stops. The same holds true for ourselves. If we don’t have “pit-stops” built into our days, there is now chance we can race at a high performance. And reading fiction is among the very best ways to get that disengaged rest. The New Yorker reports that: Reading has been shown to put our brains into a pleasurable trance-like state, similar to meditation, and it brings the same health benefits of deep relaxation and inner calm. Regular readers sleep better, have lower stress levels, higher self-esteem, and lower rates of depression than non-readers. Research at the University of Sussex shows that reading is the most effective way to overcome stress, beating out other methods like listening to music or taking a walk. Within 6 minutes of silent reading, participants’ heart rates slowed and tension in their muscles eased up to 68%. Psychologists believe reading works so well because the mind’s concentration creates a distraction that eases the body’s stress.
