Why is walking in the woods so good for you?

Scientists have advanced a wide range of theories about the specific physical and mental benefits nature can provide, ranging from clean air and lack of noise pollution to the apparent immune-boosting effects of a fine mist of “wood essential oils.” But the most powerful benefits, a new study suggests, may result from the way trees and birds and sunsets gently tug – but never grab – at our attention.

The study,..., found that volunteers suffering from depression who took a 50-minute walk in a woodland park improved their cognition, as measured by the ability to remember a random string of digits and repeat them in reverse order, compared to those who took a walk through city streets. An earlier study found similar results in subjects who weren’t depressed.
