Nature-Based Therapy: Can It Treat Anxiety & Depression?
Stress, anxiety, and depression are rising across demographics, urging patients and providers alike to seek compassionate, accessible, and holistic care. Alongside medication and psychotherapy, nature-based therapy is fast gaining credibility as a powerful mental health treatment, backed by clinical research and real-world success stories. From guided forest walks to community-based gardening, these nature-infused interventions are reshaping how we think about wellness and recovery—especially when delivered through a growing model known as green social prescribing.
What Is Nature-Based Therapy?
Nature-based therapy is a growing mental health treatment approach that intentionally uses natural environments and experiences as key therapeutic elements. Unlike unstructured time spent outdoors, these therapies are carefully designed and often facilitated by trained professionals to support emotional health and resilience. Nature-based therapy can be practiced in both individual and group settings and often targets conditions such as anxiety, depression, trauma, and burnout.
Common Modalities of Nature-Based Therapy
Here are some structured forms of nature-based interventions that continue to garner support for their physical, emotional, and psychological benefits
- Ecotherapy: Also known as nature therapy, this approach involves therapeutic techniques performed in a natural setting. It may include talking therapy with a counselor during a walk in the woods or activities like nature journaling and mindfulness outdoors.
- Forest Bathing (Shinrin-yoku): Originating in Japan in the 1980s, this practice focuses on immersing oneself in a forest atmosphere. Unlike hiking, forest bathing is slow-paced, encouraging deep sensory engagement and stress reduction through mindful observation.
- Horticultural Therapy: Gardening has long been associated with mental wellness. This structured therapy involves planting, harvesting, and caring for plants. It helps people build patience, feel better, and connect with others.
- Wilderness Therapy: Often used with youth and those struggling with addiction, wilderness therapy involves extended time in untouched natural environments. This immersive approach incorporates survival tasks, teamwork, and introspective activities to promote self-awareness and coping skills.
Each of these therapies taps into the restorative potential of nature, complementing traditional methods and creating space for holistic healing.
Green Social Prescribing Explained
Green social prescribing is an innovative healthcare model that integrates nature-based activities as part of formal mental health treatment. It enables general practitioners (GPs), therapists, and healthcare workers to refer patients to organized, nature-centric programs, rather than defaulting solely to pharmaceutical or talk therapy options.
This model moves mental health care away from just clinics. It shows that community settings and natural environments help with emotional wellness. Green prescriptions work well for people who feel isolated, have low mood, or deal with a lot of stress.
What Might a Green Prescription Include?
Patients might be referred to
- Guided group walks in natural parks
- Therapeutic horticulture programs
- Outdoor yoga, tai chi, or meditation sessions
- Conservation volunteer projects
- Forest bathing groups or nature art therapy workshops
The goal is two things: to make mental health better and to help people get involved with their community, be more active, and feel more connected to nature.
Clinical Evidence: Nature Helps Relieve Symptoms of Anxiety and Depression
The mental health benefits of nature-based therapy have been increasingly validated by rigorous academic research. One pivotal meta-study conducted by researchers at University College London in 2025 revealed that participants engaging in structured nature activities experienced significantly greater reductions in both anxiety and depression compared to control groups receiving standard care (University College London, 2025).
The study encompassed diverse demographics and was praised for its strong design and conclusive findings. Overall, nature-based interventions were associated with
- Lower anxiety and stress ratings
- Decreased symptoms of hopelessness and despair
- Increased feelings of joy, calm, and community
Science Snapshot
Researchers found participants in nature therapy sessions reported improved outcomes in mental wellbeing, even when controlling for factors such as age, socioeconomic status, and prior diagnosis (University College London, 2025).
Why Nature Heals: The Science Behind It
Modern neuroscience and psychology help explain nature’s profound impact on our mental health.
Attention Restoration Theory (ART)
Natural environments allow the brain to recover from the overload of constant stimuli—emails, screens, and crowded spaces. ART suggests that nature engages “soft fascination,” giving the cognitive system a break and allowing executive functions to recharge.
Biophilia Hypothesis
Coined by biologist E.O. Wilson, biophilia suggests humans are evolutionarily hardwired to connect with the natural world. Disconnecting from it—through urban living, technology use, and artificial environments—can contribute to anxiety, restlessness, and depression.
Reduced Cortisol and Autonomic Calming
Simply walking through a green space triggers the parasympathetic nervous system, lowering heart rate and blood pressure while regulating stress hormones like cortisol. These shifts directly counteract symptoms of anxiety and tension.
Boosted Serotonin and Dopamine Production
Reliable exposure to green spaces has been linked to higher levels of serotonin and dopamine—two neurotransmitters vital for mood regulation and reward processing.
In fact, a 2015 study by Bratman et al. found that nature experiences deactivate the subgenual prefrontal cortex—a region of the brain closely linked to rumination and depressive thought cycles (Bratman et al., 2015).
The Power of Movement + Nature
Nature-based therapy doesn’t just engage the mind—it engages the body. Physical movement, even in low-intensity forms like walking or planting, activates systems known to improve mental well-being
- Increased endorphins: Physical activity stimulates feel-good hormones, offering a natural antidepressant effect.
- Improved sleep quality: Exposure to sunlight and natural circadian rhythms promotes healthier sleep, a key component in managing anxiety and depression.
- Reduced systemic inflammation: Physical activity reduces inflammation in the body. These markers are often higher in people with depression.
When combined with nature’s visual and sensory stimuli, the psychosomatic benefits multiply. It’s a whole-body reset that supports both physical and mental health.
How Green Prescriptions Fit into Treatment Plans
Green social prescribing is rarely a standalone treatment. Instead, it enhances structured care plans, often serving as an accessible first-line intervention for early-stage mental health concerns or as a supportive tool for ongoing treatment.
A tailored treatment plan may look like
- Weekly talk therapy + Bi-weekly garden sessions
- Low-dose SSRI + Guided park walks
- Regular psychiatric follow-ups + Forest bathing on weekends
Notable Green Prescription Programs
- Walk with a Doc: Originated in the U.S., this program pairs healthcare providers with local residents for low-pressure walking sessions in parks—encouraging both physical activity and informal dialogue.
- Nature Recovery Walks (UK): These evidence-based group therapy programs combine reflective talk therapy with gentle countryside walks.
- Social Farms and Gardens (UK): Many people dealing with addiction, eating disorders, or trauma find structured work on farms. This helps them build responsibility, follow a routine, and manage their emotions.
The accessibility and low-cost nature of these programs make them particularly appealing for health systems seeking sustainable alternatives.
Who’s Leading the Way?
Nature-based mental health treatment has gained traction globally—but nowhere faster than the UK.
United Kingdom
Under the NHS Long-Term Plan, green social prescribing was formally incorporated in 2021 as part of mental health promotion strategies. More than 2,000 GP centers now offer green prescriptions, often in collaboration with local charities and community growers (NHS England, 2023).
International Adoption
- Canada: The “Parks Prescriptions” initiative allows physicians in several provinces to recommend national park visits for improved mental and physical health.
- Japan: Forest therapy trails have existed since the 1980s, and forest bathing is formally endorsed by the Japanese government as part of preventive healthcare.
- Australia: Wilderness therapy programs are used with at-risk youth and veterans experiencing PTSD or substance dependence.
- Sweden & Denmark: Educational systems include outdoor learning as therapy for children with ADD, anxiety, or autism.
The rising consensus is clear: integrating nature into public health strategies can sustainably improve population-wide wellness.
Making Nature Therapy Accessible
One challenge for the widespread adoption of nature-based therapy is fair access. People in low-income areas, cities, those with disabilities, and groups facing disadvantage often find it hard to get to natural spaces.
Strategies to Improve Access
- Pocket Parks: Miniature green spaces in vacant city lots provide immediate access to nature and reduce urban heat island effects.
- Rooftop Gardens: Hospitals and schools have found success establishing therapeutic garden areas patients and students can access easily.
- Mobile Units: Some nonprofits are now using vans equipped with soil, seedlings, and activity kits to bring nature-based therapy to underserved neighborhoods.
- Cultural Tailoring: Programs that fit the cultural backgrounds, values, and traditions of different groups are more likely to help people get involved and benefit from the therapy.
By rethinking how nature is delivered, we reduce disparities and ensure mental wellness isn’t reserved for the privileged.
When Nature Isn’t Enough
Nature-based therapy is promising—but not a cure-all.
Clinicians caution that individuals with severe mental illnesses (e.g., schizophrenia, bipolar disorder, or acute trauma) may require more intensive interventions. However, under professional guidance, even these groups can benefit from nature as a stabilizing adjunct.
Green social prescribing is also not meant to replace critical medications or psychotherapy in serious cases, but rather work synergistically with traditional strategies.
Cost-Effectiveness: Beyond the Emotional Benefits
Nature-based approaches hold massive potential to alleviate strain on overburdened healthcare systems. While initial setup costs (e.g., creating green spaces, training facilitators) may be moderate, long-term benefits include
- Reduced reliance on costly medications
- Fewer repeated clinical visits
- Greater patient self-management and autonomy
Research from NHS pilots indicates green social prescribing could curb expenditures in primary care by preventing chronic mental health flare-ups and promoting lifestyle changes.
Did You Know?
In cases of mild to moderate depression, green therapy has reduced participants’ use of medication and helped them stick better to other parts of their care plans.
How to Get Started: For You or Your Practice
For Individuals
- Start simple: Take short, mindful walks in your local green space—leave devices at home.
- Join a community group: Whether it’s gardening, hiking, or conservation, group nature activities boost both mood and connection.
- Keep a journal: Write down how you feel, how you sleep, or how you think after spending time in nature.
For Healthcare Professionals
- Get trained: Organizations like the Association of Nature and Forest Therapy offer certifications to integrate ecotherapy into clinical practice.
- Use referral directories: Many regions now have centralized registries of green therapy programs and providers.
- Normalize green talk: Educate clients on how nature may reduce anxiety or depression, just as you’d discuss exercise, nutrition, or sleep.
What’s Next: A Greener Future of Mental Health Care
The future of mental health is emerging at the intersection of science, sustainability, and social care. As more studies substantiate the impact of nature-based therapy, expect to see
- Expanded government investment in green infrastructure
- Larger clinical trials validating treatment protocols
- Integration into public insurance plans
In short, green care is moving from “alternative” to mainstream, offering scalable, affordable pathways to mental wellness.
Returning to Our Roots for Mental Wellness
Nature-based therapy reconnects us with an often-overlooked, yet deeply powerful, form of healing. By bringing together ancient human instincts and modern mental health science, interventions like green social prescribing offer timely, tangible solutions for growing emotional strain. Whether planting seeds in a community garden or feeling sunlight in a forest clearing, the path to mental clarity may begin simply—by stepping outside.
