The Health Benefits of Tree Hugging

.

You’ve done it before, probably as a child: wrapped your arms around a tree trunk, pressed your cheek to the bark, and held on. Maybe you were playing hide-and-seek or pretending the tree could hear you. What you didn’t know then is that the tree was hugging you back, in a sense, flooding your body with the same calming chemistry triggered by human touch.

Studies suggest that tree hugging offers real-world health benefits—from lowering stress hormones to boosting immune function.

What Is Tree Hugging?

Tree hugging, as the name suggests, is the practice of hugging or touching a tree for a period of time. You can maintain contact with the bark with your palms, lean against the trunk, or wrap your arms around it. Tree hugging is also a component of forest bathing, a practice proven to improve mental and physiological health.

The practice engages the senses. You start noticing the bark’s texture and temperature, along with the sounds, scents, and cool air around you.

Direct studies on tree hugging are limited, but related research on nature exposure and forest bathing shows improvements in physical health.

Improved Mood and Reduced Stress

Hugging trees reduces stress and improves overall well-being. Just as a real physical hug helps relieve stress and make us feel safe and comforted, hugging a tree appears to tap into this same biological response system.

“The most significant direct effect is thought to be due to tactile stimulation,” Yoshifumi Miyazaki, a renowned Japanese professor, researcher, and pioneer in forest therapy, told The Epoch Times. He’s authored several books and many papers on the scientific evidence of “shinrin-yoku,” the Japanese practice of forest bathing.

A Korean study found that manufacturing workers who immersed themselves in nature through barefoot walking and tree hugging over three days had less stress and improved mood.

Their blood tests showed reduced stress hormone levels and better heart-rate variability, both of which are signs of significantly less stress and negative mood.

Similarly, a Brazilian study found that students who took unhurried, deliberate walks through the woods and engaged their senses in nature through touch saw their anxiety levels drop by nearly half after each session. Students also showed sizable reductions in stress and depression, especially in parks with denser, more natural vegetation.

If hugging a tree isn’t possible, simply touching it—or even touching a wooden plank—may confer similar benefits.

One study by Miyazaki found that placing a hand on an uncoated wood surface for 90 seconds, rather than marble, tile, or steel, calmed the brain, shifting it into rest mode. Miyazaki noted that beyond forest therapy’s sensory effects, forests themselves enhance comfort. “When surrounded by a representative form of nature such as the forest, humans automatically synchronize with it and naturally experience a state of comfort,” he said—a response rooted in the body and even the genetic makeup shaped by millions of years spent adapting to natural environments.

The Chemistry of Trees

People often say a hug can protect you from illness—and hugging a tree may offer an immune lift of its own.

Trees also release electrons that may help detoxify the body.

Trees release phytoncides—wood essential oils found in leaves, bark, and sap—to defend against pests and disease. Inhaling compounds like alpha-pinene and beta-pinene, common in coniferous trees, confers measurable health benefits.

In one study, forest bathing for three days and two nights led to a drop in adrenaline—which, while helpful short term, may suppress the immune system in the long term—and increased activity of natural killer (NK) cells, which destroy virus-infected and cancerous cells. The NK cells remained active for more than 30 days after the trip.
In another experiment, researchers infused an urban hotel room with hinoki cypress essential oil overnight. Participants showed increased NK cell activity and anticancer proteins, along with drops in stress hormones—even outside the forest.
Oxytocin doesn’t just lower stress; it has antioxidant and anti-inflammatory effects, including direct scavenging of free radicals, reducing pro-inflammatory cytokines, and increasing natural antioxidants like glutathione.

Humans Are Naturally Drawn to Trees

Trees, like many elements in nature—fern leaves, river networks, cloud edges—contain fractal patterns, which are self-repeating patterns that continue to repeat themselves no matter how much you zoom in. Humans have an innate attraction to fractals, which are calming to the brain.

One thing about fractals is that they are most commonly found in nature, and humans have never been able to replicate them to the same extent.

For example, trees are made up of branches that look like miniature trees; leaves contain similar branching patterns; and if you put a leaf under a microscope, you would continue to see the same repeating patterns.

Experts suggest people find fractals calming because the visual system—and even neural wiring—is itself fractal. In a sense, nature speaks the brain’s native language.

“Our bodies—including our genetic makeup—have evolved to adapt to nature,” Miyazaki said, noting that being surrounded by it allows people to automatically synchronize with their environment and enter a state of comfort.

Even a brief look at a tree or natural setting is enough to cause a change.

In one experiment, students asked to gaze up at Tasmanian eucalyptus trees towering more than 200 feet for a single minute were later more kind and helpful toward others than students who gazed at a building of similar height.
Another study asked participants to look at a winter urban forest (trees without leaves) versus an unforested urban landscape for 15 minutes. Those who viewed the forest reported better mood, more positive emotions, greater vigor, and a stronger sense of restoration.

How to Practice Tree Hugging

Everyone interacts with nature differently.

Miyazaki therefore discourages spelling out rigid rules, such as how long to stay or whether to go barefoot. Instead, offering several practical options can help beginners ease into the practice in a way that suits them.

Here are some helpful tips for hugging trees:
  • Choose the Right Tree: Select a tree you naturally feel drawn to. Look for larger, older trees, which may release more phytoncides and bioactive compounds and offer a more comfortable, enveloping embrace.
  • Maximize Contact: Increase skin contact when possible—stand barefoot and gently rest your cheek against the bark. Urban parks can work, but natural forests provide richer sensory input and fewer distractions.
  • Consider Forest Density: Less dense forests, with fewer but larger trees spaced farther apart, tend to produce stronger therapeutic effects.
  • Be Present: Breathe slowly and deeply, notice the texture of the bark, listen to the rustling leaves, and take in the tree’s natural scent. Stay for a few minutes, or as long as feels comfortable.
