If you want to boost productivity:
“There’s this saying that our brains evolved on foot,” says neuroscientist and author, Dr Sarah McKay. “A lot of the changes that happen in terms of brain evolution and us becoming much more cognitively adept was because we moved.” And walking is still having a critical impact on our brain power – helping to prevent dementia, protect mental health and increase creative output.
Want to give your noggin a helping hand? “From a neuroscience perspective, if we get sunlight exposure in roughly 60 minutes of waking up, it provides an extra spike in cortisol,” says Dr Kristy Goodwin, who uses neuroscience to help power high performers. And don’t believe the cortisol haters – we want that flood of essential hormone in the AM to hit ‘go’ on internal processes that regulate our body clock. “[It will] put us in an alert state,” she adds.
That sunrise alarm might seem counterintuitive to all-day energy, but a morning walk can keep you sharp, as well as improve mood, memory and sleep quality. Struggling with the 3pm slump? Steps can help there, too. “Before you reach for a caffeinated drink, go outside first because sunlight exposure puts you in that focused state.”
In yet another win, walking can also boost productivity. A small Australian study published in Occupational and Environmental Medicine found breaking up long periods of sitting behind a desk with a light walk can make you feel less tired, while a Stanford University study found creative output jumped 60 per cent when participants were upping their step count.
“Walking helps ideas germinate and solve complex problems because it shifts the brain into what neuroscientists call the ‘default mode network’,” says Dr Goodwin. The reason that matters? People with more connectivity in that part of the brain tend to be better at planning, strategising and multitasking. Pay rise, incoming!
