The Japanese have taken a lead in quantifying the science behind the effects of taking a walk in the forest, which they identify as "forest bathing." The concept has nothing to do with taking an actual bath in the woods, but rather by being 'bathed' by the benefits of the woodland environment.
Recent scientific studies have proven that a walk in the woods has measurable positive effects on human health and well-being. It can boost immune systems and reduce stress. Based on these findings, several government agencies are now promoting the concept of "forest therapy."
Dr. Miyazaki of Japan's Chiba University, a leading scholar on forest medicine has conducted numerous physiological experiments to examine why forests make people feel so at ease.
"Humans have lived in nature for 5 million years. We were made to fit a natural environment. So we feel stress in an urban area," Miyazaki explained. "When we are exposed to nature, our bodies go back to how they should be."
Forests gratify the five senses by providing the sounds of birds, cool air, green leaves, the touch of trees, wild plants and grasses.
"The atmosphere of forests makes people calm," he explained. Known as "Shinrinyoku" in Japan, many countries, including Korea, Germany, Switzerland and Denmark are now studying the effects of forests and promoting the concept of forest therapy.
Studies have shown that there are other positive affects of forest therapy beyond relaxation. In their experiments, Japanese scientists uncovered hard evidence that walking in the forest decreases the blood glucose levels of diabetic patients, and that people who view forest scenery for 20 minutes have a 13 percent lower blood concentration of the stress hormone cortisol than people viewing urban settings. They have revealed that people living in areas with a higher percentage of forest cover had lower mortality rates for cancers of the lung, breast, uterus, prostate, kidney, and colon, compared with people living in areas with lighter forest cover, even after factoring in socioeconomic status.
While further research certainly is necessary, the scientific community is finally verifying what outdoor travelers have long understood: A walk in the woods is always good for you!
