Evidence-Based Guide
Nature Therapy: What It Is and How to Start Today
Nature therapy is a growing field of guided outdoor practice rooted in decades of research. It reduces stress, restores attention, and strengthens your relationship with the living world. Here is everything you need to know — and a practice you can try right now.
What Is Nature Therapy?
Nature therapy is the intentional use of natural environments and guided sensory practices to support physical, mental, and emotional health. It goes by many names — ecotherapy, forest therapy, nature-based therapy — but the core idea is the same: your body and mind evolved in relationship with the natural world, and restoring that contact has measurable healing effects.
This is not just hiking. It is not outdoor exercise. Nature therapy is guided, intentional, and relational. Where a hike focuses on distance and destination, nature therapy focuses on presence and reciprocity. You are not moving through nature. You are participating with it.
A nature therapy session might involve slow walking, sensory invitations, stillness, or simply sitting with a tree and noticing what you notice. The guide's role is not to teach you about nature but to help you remember how to be in it.
The field draws on traditions ranging from Japanese forest bathing (shinrin-yoku) to Indigenous land practices to contemporary environmental psychology. What unites them is a simple premise: nature is not a backdrop for wellness. It is the wellness.
The Evidence Behind Nature Therapy
Nature therapy is not a wellness trend. It is a field backed by decades of rigorous research across multiple disciplines. Here is what the science says.
Stress and Cortisol Reduction
In one study, Yoshifumi Miyazaki and colleagues at Chiba University found that walking in forests reduced salivary cortisol by 12.4% compared to urban walking. Participants also showed lower blood pressure, reduced pulse rate, and increased parasympathetic (rest-and-digest) nervous system activity. These effects occurred within as little as 15 minutes of forest exposure.
Attention Restoration
Rachel and Stephen Kaplan's Attention Restoration Theory (ART) explains why nature feels restorative. Natural environments engage "soft fascination" — the gentle, involuntary attention drawn by clouds, moving water, or rustling leaves. This gives your directed attention system a chance to recover. Studies show that even 20 minutes in a park setting significantly improves concentration and cognitive performance, making nature therapy a powerful complement to treatment for attention fatigue and burnout.
Immune Function
Dr. Qing Li at Nippon Medical School conducted a series of studies on forest bathing and immune response. His research found that spending two to three days in a forest environment increased natural killer (NK) cell activity by up to 50% — an effect that lasted for more than 30 days after the experience. NK cells play a critical role in the body's defense against viruses and tumors. The effect is partly attributed to phytoncides, aromatic compounds released by trees. These effects were observed after multi-day forest immersion. Rewyld offers an accessible daily practice inspired by this research.
Mental Health Outcomes
A large meta-analysis reviewed over a hundred studies and found that nature-based interventions significantly reduced symptoms of anxiety and depression. Ecotherapy programs in the UK have been recommended through NHS social prescribing programs as a complement to traditional treatment. Separate research by Stanford's Gregory Bratman showed that a 90-minute nature walk reduced rumination — the repetitive negative thinking pattern associated with depression — and decreased neural activity in the subgenual prefrontal cortex.
The takeaway: nature therapy is not metaphor. It produces measurable changes in your hormones, your immune system, your brain activity, and your mood. And unlike many interventions, the side effects are almost entirely positive.
Types of Nature Therapy
Nature therapy is an umbrella term. Within it, you will find a range of practices, each with its own lineage, setting, and emphasis.
Forest Bathing (Shinrin-yoku)
Originated in Japan in 1982, forest bathing involves slow, immersive walks through forested environments with an emphasis on sensory engagement. Sessions are typically two to three hours, guided by a certified practitioner, and often include a tea ceremony. Forest bathing is probably the most researched form of nature therapy.
Ecotherapy
A clinical approach that integrates nature-based activities into therapeutic practice. Ecotherapy can include conservation volunteering, gardening, animal-assisted therapy, and wilderness experiences. It is often facilitated by licensed therapists and used to address anxiety, depression, and trauma. In the UK, ecotherapy is sometimes prescribed alongside conventional treatment.
Wilderness Therapy
Multi-day or residential programs set in backcountry environments. Wilderness therapy combines outdoor skills, group process, and individual counseling. It is most commonly used for adolescents and young adults dealing with behavioral, emotional, or substance use challenges. Programs are typically staffed by licensed clinicians.
Mindful Hiking
Combines elements of walking meditation with trail-based movement. Mindful hiking emphasizes present-moment awareness during the hike itself rather than focusing on pace or distance. It is accessible to anyone with access to a trail and does not require formal certification to practice.
Nature-Based Mindfulness
What Rewyld offers
Short, guided sensory practices designed for daily life. Nature-based mindfulness borrows from forest bathing and outdoor mindfulness traditions but is adapted to be done in 10 minutes, anywhere — a backyard, a park bench, a patch of urban green. It is designed for people who cannot commit to a three-hour forest walk but still want the regulatory benefits of intentional nature contact.
A Preview
What a Nature Therapy Practice Looks Like
Here is a taste of what Rewyld guides you through. Find any outdoor space and give yourself ten minutes.
Arrive
Stand still. Three slow breaths. Feel the ground under your feet. Close your eyes and expand your hearing outward—the closest sound, then the farthest. You are here.
Sense
Open your eyes with a soft gaze. Let your vision be drawn to whatever catches it. Then find something natural to touch—bark, grass, stone. Feel its temperature and texture. Let the living world enter through your senses.
Close
Stand still again. Breathe slowly. On each inhale, receive. On each exhale, offer your attention back. Take one last look around. Then carry this pace with you.
This is a preview. The full experience in Rewyld includes audio guidance, progressive sequences, and a library of 10-minute practices designed for daily life.
Find a Certified Nature Therapy Guide
Working with a trained guide transforms nature therapy from something you read about into something you feel. Certified guides have completed rigorous training programs — often through organizations like the Association of Nature and Forest Therapy (ANFT) or Kripalu Center for Yoga and Health — and are skilled at creating conditions for deep presence in the natural world.
A good guide does not lecture. They offer invitations. They hold space. They help you slow down enough that nature can do what it already knows how to do: bring you back to yourself.
Whether you are looking for a single session or an ongoing practice, finding a guide in your area is one of the most powerful steps you can take.

Frequently Asked Questions About Nature Therapy
Is nature therapy evidence-based?
Yes. Decades of peer-reviewed research support nature therapy. Studies published in journals like Environmental Health and Preventive Medicine and the International Journal of Environmental Research and Public Health show that time in natural environments lowers cortisol, reduces blood pressure, improves mood, and strengthens immune function. Forest bathing research from Japan has demonstrated measurable increases in natural killer (NK) cell activity after forest immersion.
How long is a nature therapy session?
Sessions vary widely. A traditional forest bathing walk guided by a certified practitioner typically lasts two to three hours. However, research shows that even 10 to 20 minutes of intentional time in nature produces measurable benefits. Rewyld practices are designed around 10-minute sessions that fit into daily life — a meaningful daily dose of nature contact.
Do I need a guide?
You do not need a guide to benefit from nature, but a skilled guide can deepen the experience significantly. Certified nature therapy guides are trained to hold space, offer invitations that open your senses, and help you develop a reciprocal relationship with the living world. For beginners, a guide or a guided app like Rewyld can make the difference between a walk and a practice.
What is the difference between forest bathing and nature therapy?
Forest bathing (shinrin-yoku) is one form of nature therapy that originated in Japan in the 1980s. It specifically involves slow, immersive time in forested environments. Nature therapy is the broader category that includes forest bathing, ecotherapy, wilderness therapy, horticultural therapy, and nature-based mindfulness. Think of forest bathing as one practice within the wider nature therapy field.
