In recent years, research has demonstrated that spending time in nature can help with everything from anxiety to attention deficit disorder to high blood pressure. Florence Williams knows this as well as anyone: her celebrated 2017 book The Nature Fix, explained the science behind the many physiological and emotional benefits of being in natural environments. So when she went through a painful divorce from her husband of 25 years, she turned to the outdoors for healing—and chronicled her experiences in her latest book, Heartbreak. In this episode, we eavesdrop on a conversation between Williams and Outside contributing editor Elizabeth Hightower Allen to learn about broken-heart syndrome (a real medical condition), the chemical explanation for rebound relationships, and whether taking a solo river trip immediately after a breakup is the best idea.
