A recent study published in the Proceedings of the National Academy of Sciences found that being in a park, away from a city street, reduces blood flow to your subgenual prefrontal cortex, which is the area of your brain associated with negative thoughts. “Happiness is about feeling centered, focusing on the good around you and seeing that there is a world bigger than yourself,” said Theresa Herring, an Evanston-based licensed therapist. “Getting out into nature is a great way to shift into that perspective.”
