After my friend's medical diagnosis, I thought I was taking him into the mountains to help him escape the reality that had become his life. Instead, I realized the forest wasn't offering an escape at all—it was gently helping him reconnect with himself and return to the life that still awaited him, one breath and one step at a time.”
On this particular afternoon, I drove my friend into the mountains above his hometown of Julian so we could take in the view and sunset from above. After parking, we wandered only a short distance down the trail before settling into a quiet conifer forest, surrounded by towering Ponderosas, Jeffrey pines, and Douglas-firs. The air was warm and we noticed the fragrance of dried pine needles and butterscotch…and for a little while, the world and stress beyond the trees seemed to fade away. We weren't meditating. We weren’t praying. We weren’t exercising. We weren’t trying to accomplish anything. We simply sat there.
Sunlight made its way through the tall canopy. Stellar’s Jays announced our arrival. A squirrel darted across the dirt trail, completely unconcerned with my friend’s chronic discomfort or the anxiety he was dealing with.
For the first time in weeks, maybe months, he told me his body felt relaxed. His busy mind felt quiet. He hadn't escaped his life. He had stepped back into it.
At the time, I couldn't explain why something so simple felt so profound. Years later, I discovered there was a name for what we had experienced. Not just forest bathing, but something even broader: Forest Medicine.
Most people have now heard of Shinrin-Yoku, or forest bathing—a practice that began in Japan in the early 1980s and encourages people to immerse themselves in the restorative atmosphere of the forest through their senses.
Originally introduced as a public health initiative to help reduce stress, forest bathing has since inspired decades of scientific research. In a recent review, Dr. Qing Li—one of the world's leading researchers in this field—describes how the science has evolved into what he calls Forest Medicine.
This isn't medicine in the traditional sense. There are no prescriptions. No procedures. No buildings. No rooms.
Instead, Forest Medicine explores how spending intentional time in forest environments influences the body's interconnected systems, supporting health before illness develops.
It's a shift in perspective—from treating disease after it appears to nurturing well-being every day.
One of the most fascinating ideas in the review is that our health isn't controlled by isolated systems working independently.
Instead, our minds and bodies are constantly communicating through what scientists call the psycho-neuro-endocrino-immune network.
It's a long complicated name for a beautifully simple idea. Our thoughts affect our nervous system. Our nervous system influences our hormones. Our hormones shape our immune response. Our immune system, in turn, affects how we feel physically and emotionally. Everything is connected.
Think about a stressful day at work. Your heart beats faster. Your muscles tense. Your shoulders don’t behave normally. Your breathing becomes shallow. You might sleep poorly that night.
If stress continues for weeks or months, your immune system can also be affected. The body doesn't separate emotional stress from physical health.
Neither should we.
This is where Forest Medicine becomes so compelling.
Rather than targeting one symptom, researchers have found that forest environments appear to influence multiple systems at once.
Over the past two decades, studies have associated time in forests with:
None of these changes happen because the forest is “magic." They happen because human bodies evolved in relationship with the natural world. Perhaps the real surprise isn't that forests help us feel better. Perhaps it's that we've spent so much of modern life separated from them.
Looking back, I think the greatest gift the forest gave my friend wasn't silence. It was perspective. He told me back then that he hadn't noticed how much noise he'd been carrying. End of life conversations. The distraction of television. The distraction of music. Podcasts.
Even in his state, he felt constant pressure to be informed and distracted by technostress.
When all of that disappeared for an hour beneath the trees, he realized something surprising. His mind wasn't naturally anxious. It was exhausted.
The forest didn't ask him to think differently. I think it simply gave his brain a chance to recover.
When most people think about healthcare, they imagine doctors' offices and hospitals. Forest Medicine invites us to consider another possibility. What if health isn't only about treating illness? What if it's also about cultivating resilience before illness begins? That idea resonates deeply with me.
We already understand that regular movement supports heart health. Nutritious food supports our bodies. Quality sleep restores us. Meaningful relationships strengthen emotional well-being. Perhaps regular time in nature belongs on that same list. Not as a replacement for medical care, but as an essential part of living well.
One thing I've learned from spending time on trails is that healing is rarely dramatic. Most of the time, it arrives quietly. You sleep through the night. You laugh a little more easily. You notice your breathing has slowed. You're more patient. You feel less hurried, even though your schedule hasn't changed.
These aren't headline-worthy transformations. But they matter. Small changes, repeated over time, become lasting changes. Just as a forest grows one ring at a time, our well-being is often built through small, consistent moments of restoration.
One of the things I appreciate most about Forest Medicine is that it isn't about perfection. You don't need a remote wilderness. You don't need expensive equipment. You don't even need hours of free time. You simply need to begin noticing. Take a slow walk through a local park. Leave your phone at home or in your pocket on “airplane” mode.
Listen to the wind instead of the news for a little while. Notice the scent of incense cedar after rain or the warmth of sunlight filtering through leaves. The forest doesn't ask you to perform. It only asks you to be present.
As a licensed guide with the American of Nature & Forest Therapy, we often notice something remarkable. People arrive carrying stress they didn't realize they were holding. As the experience unfolds, their breathing softens. Their conversations become quieter. Their attention shifts from what needs fixing to what is already here.
Long before researchers measured cortisol or immune cells, people understood that forests were places of renewal. Today, science is helping explain why.
Forest Medicine doesn't suggest that trees replace physicians or that a walk in the woods cures every illness. Instead, it reminds us of something both ancient and hopeful: Our relationship with nature is part of our health. Perhaps healing isn't always about adding something new to our lives. Sometimes it's about returning to something we've always needed. The forest has been waiting all along.
Maybe it's time we listened.

This review describes the evolution of Forest Medicine from the practice of Shinrin-Yoku (forest bathing) into an interdisciplinary field of preventive medicine. It proposes that forest experiences support health through the interconnected psycho-neuro-endocrino-immune network, drawing on more than two decades of research into the physiological and psychological effects of spending time in forest environments.
