A large and growing body of research has found that time outdoors makes us happier and healthier, but there’s relatively limited science explaining why. According to findings published last summer in the journal Emotion, a big part of the answer may be awe. Studies conducted by psychologists at the University of California at Berkeley showed that feeling awe during a nature experience has a singular ability to lower stress and improve our overall well-being. Even more compelling, the research suggests that we don’t need to climb a mountain or run a river to get the healing power of awe—the simplest moments outside are all it takes. For this final episode in our Nature Cure series, we talk to the scientist who led the Berkeley study, as well as a man who says awe saved his life.
