What's the cure for our modern malaise of stress, distraction, and screen-addiction? Nature, of course. But while many people advocate the benefits of getting outside, we are only just beginning to understand what really happens to us when we venture out the door. For her new book, The Nature Fix, Outside contributing editor Florence Williams expands on a 2012 feature she wrote about Japanese forest bathing, delving deep into the fascinating science behind the restorative power of wild places. Editor Chris Keyes talks with Williams about the research being done around the world to investigate how spending more time in nature can make us healthier, happier, and even more creative.
