“In short, the brain evolved in a biocentric world.” ~ E. O. Wilson

 

We’ve carried the daily stress of modern life for so long that it feels normal. Long before phones and computer screens invaded our lives, our bodies had evolved to the rhythms of nature. It should be no surprise that research is revealing the importance of nature to our mental, physical, and emotional health. In his 1984 book Biophilia, biologist Edward O. Wilson developed and popularized the idea that we feel at home in nature because it shaped our evolution.

The Japanese have been leaders in exploring this connection through a practice known as shinrin-yoku, or forest bathing. As described in The Nature Fix by Florence Williams, forest bathing encourages us to spend time in nature, from quick visits to a local park to longer stays in wild places. Rooted in Shinto and Buddhist traditions, shinrin-yoku is not prayer or meditation, but immersion in the forest through the senses. In Japan, the practice is widely embraced, with over 40 designated forest therapy trails and nearly a quarter of the population participating.

Research shows measurable benefits: reduced stress hormones, lower blood pressure, improved mood, and a stronger immune function. Shinrin-yoku participants are encouraged to engage all five senses, rubbing their hands over the rough bark of a tree, tasting and smelling a wild herb, and listening to a soft breeze filtering through the trees. Anthropologist Yoshifumi Miyazaki puts it simply: “Throughout our evolution, we’ve spent 99.9 percent of our time in nature.” Our bodies still expect that environment. When we return to it, even briefly, something inside us settles.

As I write this post, rain is beginning to fall, spattering on the leaves and sidewalk, its calming fragrance filling my lungs. I can feel the stress drain from my shoulders. Qing Li, chairman of
