To rest is to restore.

The brain’s capacity to focus on a task or stimulus is limited, with long periods of sustained attention resulting in fatigue.

Studies suggest that interaction with natural environments can work to counteract this exhaustion of our attention, and in turn benefit our cognitive function.

Steven Kaplan’s Attention Restoration Theory indicates that the modest nature of stimuli such as forests, rivers and sunsets provides space for a gentle mode of focus, in which our attention capacities may be restored. Man-made environments have not been found to have the same effect.
