Forest therapy has many physiological and psychological benefits
Shinrin-yoku gives the phrase tree hugging a whole new meaning.
“I felt its strength and courage. I felt a lot of love,” said Glenda Barton of Santa Rosa after hugging a giant redwood in the park.
Barton was one of about 20 people being led by Karen Sapper on a Forest Therapy walk in Sugarloaf Ridge State Park on a recent Saturday morning.
“Shinrin-yoku” literally translated from Japanese where the practice began, means “forest bathing.” Better described as forest therapy, the practice is a “meditative style of walking, but it wouldn’t be considered meditation,” Sapper said.
Sapper is a forest therapy guide, certified by Sonoma County-based Association of Nature and Forest Therapy, who leads individuals or groups on strolls in and through forested trails teaching the sensory-opening activities that can lead to calmer minds, lowered blood pressure and overall relaxation.
“The practice is essentially coming into a quality of presence through heightened sensory awareness,” Sapper said.
“Bathers” gathered in a large circle on that cool, crisp Saturday morning, as fog wrapped the hillsides where a howling coyote perched on a rock. Before they set off down a trail, Sapper explained to the forest therapy walkers – most on their first of such hikes – the philosophy and routine of Shinrin-yoku and its many reported health benefits.
There is a neuroscience connection to forest therapy, Sapper said, with medical practitioners now prescribing it to patients.
In a 2017 article in International Journal of Environmental Research and Public Health titled “Shinrin-yoku (forest bathing) and nature therapy: a state-of-the-art review,” the authors identified physiological, therapeutic benefits to the practice. Among the recorded benefits are improvements to the immune system, cardiovascular system and the respiratory system. It also can help with such things as hypertension, allergies, mood disorders such as anxiety or depression, and overall mental relaxation.
“It is a practice that provides an opportunity to deeply connect with the benefits of nature,” Sapper said.
Sapper led the group to a small clearing near a creek and passed out bay laurel leaves to each hiker. Rub it in your hands, then bend it until it cracks, she said, then touch it to your tongue. The leaves released an invigorating and earthy aroma.
Looking at the surrounding trees, Sapper tells of the mutually-beneficial relationship between human and trees – humans take in the oxygen the trees release, and the trees take in the carbon dioxide and carbon monoxide humans produce, she said.
“Feel your feet planted to the earth,” Sapper said, “and close your eyes.” Instructing hikers to turn a quarter-turn at a time, Sapper asked them to be aware of the wind, the light coming through closed eyelids, the aromas, the songs of birds, a babbling brook. “With eyes open, take particular note of something in view.”
Passing around a “talking stick,” each took a turn sharing what they observed – the beauty of a piece of grass swaying in the wind, the feeling of space, the mountains and fog, the patterns in the trees, were some of the observations.
Sapper was leading the group on a series of “invitations” – instructions on how to open the senses and mind during their three-quarter mile long walk.
“Each invitation has a body of scientific research behind it on how it is beneficial to the body,” Sapper said.
