It may seem obvious – as you push on through a long run, veering wildly between sensations of agony and elation – that running can have a huge effect on your state of mind. It is an intuitive idea that a growing number of neuroscientists have begun to take seriously, and in recent years they have started to show us what actually plays out on the hills and valleys of your grey matter as you run.
Their findings confirm what many runners know from their own experience: we can use running as a tool to improve the way we think and feel. And we are now learning precisely why running can return focus, vanquish stress and improve mood. Plus we know why – if you’re lucky – you might get a brief glimpse of nirvana.
It would be crazy to believe that running is a universal solution to all of our psychological challenges. Indeed, from your brain’s perspective, you may not want to push it too hard. German neuroscientists scanned the brains of some of the competitors before, during, and after the TransEurope Foot Race, in which competitors slog through 3,000 miles, over 64 consecutive days. In the middle of this absurdly extreme ultramarathon, the runners’ grey matter had shrunk in volume by 6%: the ‘normal’ shrinkage associated with old age is just 0.2% each year. Luckily, the story doesn’t end too badly: eight months later the runners’ brains were back to normal.
