Nature Therapy and Mental Health: What New Research Tells Us About Our Practice

A Forest Therapist's Reflection

As a forest therapy guide, I've witnessed countless moments of transformation as participants connect with nature. However, as our field grows, it's crucial that we examine the scientific evidence behind our practice. A new systematic review published in March 2024 has caught my attention, challenging some of our assumptions while validating others.


Understanding the Research Landscape

When I first began guiding forest therapy sessions, I relied heavily on intuition and traditional knowledge. Today, as I read this comprehensive review of eight clinical trials, I find myself both encouraged and humbled by what the science reveals about our work.

What the Research Examined

The researchers looked at key measures we often discuss in our practice:

  • Stress levels (both psychological and physiological)

  • Anxiety and depression markers

  • Blood pressure changes

  • Cortisol levels (our primary stress hormone)


Key Findings Through a Guide's Lens

The Stress Response

As a guide, I've always noticed how participants' shoulders drop and breathing deepens during our forest sessions. The research partially validates these observations, showing significant stress reduction in some studies using the Stress Response Inventory. However, I must acknowledge that other measurements showed mixed results.

Physiological Changes

Here's where the research particularly interests me. Those cortisol studies we've often cited? The review found some positive changes in cortisol levels, but raises important questions about methodology. As someone who has built programs around the "science of forest bathing," I need to be more nuanced in how I present these benefits to participants.


What This Means for Our Practice

Rethinking Session Design

The studies examined various approaches:

  • Short 15-minute interventions

  • Weekly sessions over 6-8 weeks

  • Different natural settings

As a practitioner, this diversity of approaches both validates our flexibility and challenges us to be more precise. I'm now restructuring my programs to better document and measure outcomes, inspired by the research protocols described.

Cultural Considerations

One fascinating aspect of this review is its observation that most research comes from Asian countries. As someone practicing in Southern Ontario, this reminds me to be mindful of cultural differences while applying research findings to our local context.


Honest Reflections on Limitations

The review's conclusion feels challenging at first: "limited support for advocating nature-based therapeutic interventions as a primary approach." However, as a seasoned guide, I interpret this not as a dismissal of our work, but as a call to:

  • Design more rigorous programs

  • Better document our outcomes

  • Be more precise in our claims

  • Integrate standardized measurement tools


Moving Forward: A Guide's Action Plan

Based on this research, I'm implementing several changes in my practice:

Session Documentation

  • Adding standardized mood assessments

  • Creating clear protocols for different group needs

  • Documenting environmental conditions

Program Design

  • Offering both short and long-term engagement options

  • Including control measures where possible

  • Being more specific about expected outcomes

Client Communication

  • Being more precise about benefit claims

  • Acknowledging the emerging nature of our research base

  • Emphasizing personal experience while being honest about scientific evidence


Personal Conclusion

As someone who has dedicated their professional life to forest therapy, this review doesn't diminish my belief in our work. Instead, it challenges us to grow more rigorous in our approach. The magic I witness in the forest remains real – we're simply being asked to document and understand it better.

For my fellow guides reading this, I encourage you to:

  • Study this research carefully

  • Implement more structured evaluation methods

  • Contribute to building our evidence base

  • Stay humble and curious about what we don't yet know

The forest has always been our teacher. Now, science is helping us understand exactly how and why our work matters, while reminding us there's still much to learn.
