What is Forest Therapy?
Forest Therapy is simply taking the time to slow down and immerse your senses in the atmosphere of the forest. Imagine a moving meditation, where you bring your awareness to the wonder of the natural world around you.
The term comes from the Japanese practice Shinrin-yoku, which translates to "forest bathing." Shinrin-yoku was introduced by the Japanese government in the 1980s as a public health initiative, when many people moved from rural areas to urban centres and began experiencing stress-related illness and disease.
On a Forest Therapy walk, you can expect to move slowly through the landscape —covering around 1–1.5 km over 2–3 hours, much slower than you would on a typical bushwalk. Your guide offers a series of gentle invitations to help tune your senses to the sights, sounds and scents of the forest.
After a walk, participants often feel calmer and more connected to nature. Many report feeling less anxious and stressed, and more content, peaceful and refreshed.
Professor Yoshifumi Miyazaki began researching Forest Therapy in the 1990s and summed it up beautifully when he said, "It is clear our bodies still recognize nature as our home."
There are now more than three decades of research demonstrating the benefits of Forest Therapy, and it is recognised as an evidence-based public health practice in countries including Japan, South Korea and China. It is also practised widely across Europe, the United States and Australia. Japan has more than 60 dedicated Forest Therapy centres, and in South Korea, doctors can prescribe "green prescriptions" that encourage patients to spend time in nature.

The Science Behind Forest Therapy
Forest Therapy is not simply a walk in nature— the practice is supported by a growing body of scientific research.
This research how shown our exposure to Phytoncides play a crucial role in the wellbeing effects of Forest Therapy. Phytoncides are airborne organic compounds released by trees which have anti-bacterial, anti-fungal, anti-microbial, anti-inflammatory and anti-viral effects.
When we inhale these Phytoncides we get a ‘surge’ in Natural Killer (NK) cells. These are white blood cells (lymphocytes) that form part of our immune system and can fight off abnormal cells, including cancer and tumor cells.
While, slowing down in nature and engaging in mindful sensory activities activates the parasympathetic nervous system—our body's "rest and digest" state. This helps counter the stress-driven "fight-or-flight" response, reducing heart rate, blood pressure and stress hormones while promoting relaxation and recovery.
Benefits include:
Reduction of cortisol (stress hormone)
Normalization of blood pressure and heart rate
Increased natural killer (NK) cell activity resulting in a boosted immunity
Improved mood and reduction in anxiety
Enhanced focus and concentration
Improved sleep quality
Research shows some benefits can last for up to four weeks after just one Forest Therapy session.
