More than a thousand studies (and growing) show that time spent in nature can have a reset effect, washing away the anxieties and stresses of everyday life. A 2019 study published in Current Directions in Psychological Science, for instance, found that exposure to natural environments improves memory, cognitive flexibility, and attentional control, while a 2022 study published in Cities & Health found that walking in an urban park can improve mood. There's even a name for time intentionally spent in nature—forest bathing.
