A 2008 study that was published in Psychological Science revealed that the brain becomes both calmer and sharper after a person spends time in a quiet setting close to nature. Other research also concludes that walking in green spaces puts the brain in a meditative state.

Even a walk in a 5-minute walk in the park can have an immediate calming effect on the mind.
