Natural Medicine in Mental Health

Nature as Medicine: Forest Therapy, Gardening, and the Future of Mental Health Care

In a world that moves quickly and demands constant attention, many nervous systems are living in a near-continuous state of alert. Anxiety, depression, burnout, and trauma are not only psychological experiences—they are physiological ones. Increasingly, mental health care is rediscovering something humans have always known: time in nature can be deeply therapeutic.

Nature therapy, forest therapy, and gardening are not replacements for psychiatric care or psychotherapy. Instead, they are powerful, evidence-supported complements that help regulate the nervous system, restore attention, and reconnect people with a sense of safety and meaning.

What Is Nature Therapy?

Nature therapy refers to intentional engagement with natural environments to support mental, emotional, and physical well-being. This can include:

• Spending time in green spaces

• Walking or sitting in forests

• Gardening or caring for plants

• Mindful observation of natural surroundings

The goal is not productivity or exercise, but presence and regulation—allowing the nervous system to settle through sensory connection with the natural world.

Forest Therapy: The Practice of “Shinrin-Yoku”

Forest therapy, also known as Shinrin-yoku or “forest bathing,” originated in Japan and is now supported by a growing body of research. It involves slow, intentional time in forested environments, engaging the senses rather than striving toward a destination.

Research has shown that forest therapy can:

• Reduce stress hormones such as cortisol

• Lower blood pressure and heart rate

• Improve mood and emotional regulation

• Support immune function

• Decrease symptoms of anxiety and depression

From a psychiatric perspective, forest therapy helps shift the nervous system out of chronic fight-or-flight and into a state of rest, repair, and connection.

Gardening as Mental Health Care

Gardening is one of the most accessible and impactful forms of nature-based therapy. It combines movement, sensory input, responsibility, and rhythm—elements that are especially beneficial for mental health.

Gardening can support:

• Depression, by fostering purpose and accomplishment

• Anxiety, through grounding and sensory engagement

• Trauma recovery, by restoring agency and safety

• ADHD, by improving focus and regulating energy

For many people, gardening also offers a gentle re-entry into caring—for something outside themselves, and often, eventually, for themselves.

The Nervous System and Why Nature Helps

Modern mental health challenges often reflect nervous system dysregulation rather than personal failure. Nature provides consistent, non-judgmental sensory input—sounds, textures, light, and movement—that helps the brain recalibrate.

Unlike screens or urban environments, natural settings:

• Reduce cognitive overload

• Restore attentional capacity

• Promote parasympathetic (calming) nervous system activity

• Encourage slower, more embodied awareness

This is especially meaningful for individuals with trauma histories, where the body may struggle to feel safe indoors or in highly stimulating environments.

Integrating Nature-Based Practices Into Mental Health Care

In integrative psychiatric and therapeutic settings, nature-based interventions can be woven into care in many ways:

• Encouraging time outdoors as part of treatment planning

• Incorporating walking or outdoor therapy sessions when appropriate

• Using gardening as a therapeutic activity in group or community settings

• Supporting patients in building sustainable, nature-connected routines

These practices work best when individualized and used alongside evidence-based treatments such as therapy, medication, nutrition, and sleep support.

Nature, Meaning, and Healing

Beyond symptom reduction, nature offers something deeper: connection. Many people report that time in forests or gardens brings a sense of belonging, perspective, and spiritual grounding.

Across cultures and folk healing traditions, nature has long been seen as a teacher, a witness, and a healer. Modern mental health care is beginning to honor this wisdom—not by romanticizing nature, but by recognizing its role in human regulation and resilience.

Who May Benefit Most?

Nature-based therapies may be especially supportive for individuals experiencing:

• Chronic stress or burnout

• Anxiety or mood disorders

• Trauma and nervous system dysregulation

• Grief or major life transitions

• Disconnection from body or meaning

Even small, consistent interactions with nature can have meaningful effects.

Final Thoughts

Nature therapy, forest therapy, and gardening remind us that healing does not always require doing more. Sometimes, it requires slowing down, listening, and reconnecting—to the body, the breath, and the living world around us.

When thoughtfully integrated into mental health care, nature becomes not an alternative, but a mainstay in healing—supporting regulation, resilience, and the quiet work of restoration. Ask us how to integrate nature therapy into your treatment today!
