In a piece for The New Yorker, Ferris Jabr writes about the benefits of walking, and how walking influences the way we think, write, and come up with ideas.
What is it about walking, in particular, that makes it so amenable to thinking and writing? The answer begins with changes to our chemistry. When we go for a walk, the heart pumps faster, circulating more blood and oxygen not just to the muscles but to all the organs—including the brain. Many experiments have shown that after or during exercise, even very mild exertion, people perform better on tests of memory and attention. Walking on a regular basis also promotes new connections between brain cells, staves off the usual withering of brain tissue that comes with age, increases the volume of the hippocampus (a brain region crucial for memory), and elevates levels of molecules that both stimulate the growth of new neurons and transmit messages between them.
Walking at our own pace creates an unadulterated feedback loop between the rhythm of our bodies and our mental state that we cannot experience as easily when we’re jogging at the gym, steering a car, biking, or during any other kind of locomotion. When we stroll, the pace of our feet naturally vacillates with our moods and the cadence of our inner speech; at the same time, we can actively change the pace of our thoughts by deliberately walking more briskly or by slowing down.
Because we don’t have to devote much conscious effort to the act of walking, our attention is free to wander—to overlay the world before us with a parade of images from the mind’s theatre. This is precisely the kind of mental state that studies have linked to innovative ideas and strokes of insight.
Excellent! 🙂 Thanks for sharing it, Dimitri. Cal Newport has also written on the benefits of walking to work on problem-solving and to ignite creativity overall: http://calnewport.com/blog/2014/01/03/on-quiet-creativity/ There’s a whole chapter in his latest book (Digital Minimalism) where he develops on this, citing many examples of notable people. He recommends especially walking outdoors, in nature.
Thanks for the link, Walter!
