It sounded more like a lark than a scientific study when a handful of Japanese researchers set out to discover whether something special–and clinically therapeutic–happens when people spend time in nature. They were inspired by a new recommendation from the Forest Agency of Japan, which in the early 1980s began advising people to take strolls in the woods for better health. The practice was called forest bathing, or shinrin-yoku, and it was believed to lower stress–but that hadn’t been proved. Since then, a large body of evidence has shown that spending time in nature is responsible for many measurable beneficial changes in the body.
