Shinrin-yoku is a term that means "taking in the forest atmosphere" or "forest bathing." It was developed in Japan during the 1980s and has become a cornerstone of preventive health care and healing in Japanese medicine. Researchers primarily in Japan and South Korea have established a robust body of scientific literature on the health benefits of spending time under the canopy of a living forest. Now their research is helping to establish shinrin-yoku and forest therapy throughout the world.
The idea is simple: if a person simply visits a natural area and walks in a relaxed way there are calming, rejuvenating and restorative benefits to be achieved.
We have always known this intuitively. But in the past several decades there have been many scientific studies that are demonstrating the mechanisms behind the healing effects of simply being in wild and natural areas. For example, many trees give off organic compounds that support our “NK” (natural killer) cells that are part of our immune system's way of fighting cancer.
We recognize that forest therapy approaches such as Shinrin-yoku have roots in many cultures throughout history. John Muir wrote, “Thousands of tired, nerve-shaken, over-civilized people are beginning to find out that going to the mountains is going home. Wilderness is a necessity.
