A small new study from the University of Victoria compared the impact of “green exercise” vs. the same exercise done indoors (in this case, a short walk). Using electroencephalography to measure the impact on cognitive function across almost all brain measures, exercise in nature proved the winner. It had a significantly bigger impact on memory, concentration and thinking speed. The researchers concluded that with growing urbanization and sedentary time indoors, understanding the “nature effect” on cognition is increasingly key.
