Inside The Genius Japanese Practice That Boosts Your Immune System & Eliminates Stress Instantly

Originally from Japan, forest bathing—or shinrin-yoku in Japanese—isn't what it sounds like. Yes, it involves a trip to the forest, but you won't be stripping down and jumping into a serene lake surrounded by larger-than-life trees. Instead, it's a meditative moment or walk spent immersing yourself in all the forest has to offer: clean air, peace and quiet, and immune-boosting benefits.

Research1 has long shown the positive impact of nature and greenery on our overall health, and forest bathing is no exception. This spiritual practice is scientifically proven to boost the immune system2, lower your heart rate, reduce blood pressure3, and improve our overall sense of well-being.

Forest therapy was founded on the idea that as a species, we spent the first few million years of our existence in the forest. Now we reside in cities and suburbs and are surrounded by all kinds of stimuli. This has led to a tremendous amount of stress on our minds and bodies that result in negative health consequences.

Beyond the basic benefits of spending time in nature—increased well-being, lower blood pressure, the list goes on—forest bathing has some unique health benefits involving a compound called phytoncides4. "Trees shower (or bathe) themselves in an antimicrobial, antifungal, antibacterial compound called phytoncides," explains Ben Page, founder of Shinrin Yoku LA. "This is how trees combat disease. When humans inhale these phytoncides, it triggers the human body to produce a specialized white blood cell called NK cells, or Natural Killer cells." These NK cells are responsible for attacking cancerous and tumorous growths in the body, improving overall immune strength.

So, why is forest bathing more popular than ever this year? Amos Clifford, founder and director of U.S. Association of Nature & Forest Therapy, thinks it has to do with how much stress regular use of smartphones and other technology have added to our lives.

"I believe the reason for the growing popularity of this practice has to do with an instinctive reaction to the growing dominance of devices in our lives," he explains. "And when people practice forest bathing, the benefits are so immediately felt that people want more."

While the scientifically proven benefits are one reason so many people turn to forest therapy, Clifford adds that its popularity has a lot to do with the need for connection. "Many people who I have guided feel more connected, not just to nature but to themselves. Putting aside the habitual stressors of daily life, the constant immersion in technology, and the rushing about and exhaustion is a bit like waking up from a bad dream. As clarity descends, people remember who they are and what is important in life. They feel refreshed, renewed, and restored."
