Researchers from Heriot-Watt University in the U.K. tracked the brainwaves of study participants, as they walked through an old shoping district, a park, and a bustling commercial area. Researchers found these participants entered a meditative state while walking through the park. The British study is the latest in a string of research on the benefits of spending time in nature. A study from 2011 found that a forest stroll could lower the stress hormone coristol by 12.4 percent versus strolling through an urban environment. Read more about the study from Outside magazine.
