Walking in nature for as little as 15 to 20 minutes can improve your attention span – even if you do not always enjoy it.

Environmental neuroscientist Marc Berman explains how the natural environment can help restore people’s frazzled, overstimulated nervous systems in his new book, Nature and the Mind: The Science of How Nature Improves Cognitive, Physical and Social Well-Being.

Berman, founder and director of the Environmental Neuroscience Laboratory at the University of Chicago in the US state of Illinois, is also professor and chair of the university’s psychology department and co-director of the master of computational social science programme.

Through his lab’s research, Berman and his team have found that walking for longer periods of time – about 50 minutes – can boost cognitive function, but spending just 15 to 20 minutes in nature offers a noticeable benefit.
In one study, Berman and his team asked people to walk at different times of the year in Michigan state: in June when it was pleasant and in January when it was 25 degrees Fahrenheit (minus 3.9 degrees Celsius) and the trees were bare. The summer group was blissfully happy; the winter group was not.

“But they still showed the same cognitive benefit as the people that walked in June,” he said. “For these cognitive benefits, it’s not about liking the interaction. It’s something deeper. It’s how we process natural stimulation.”
