🌿 Walking in Nature vs. SSRIs: Exploring Two Paths Through Depression
By Dr. Rich Oberleitner, DC

Depression touches all corners of our society, often silently. Millions wake up each day navigating a fog of sadness, anxiety, or numbness, wondering if they’ll ever feel “normal” again. In response, our modern medical system often reaches first for a prescription pad—usually for SSRIs (Selective Serotonin Reuptake Inhibitors) like Prozac or Zoloft. But increasingly, both science and lived experience suggest that an ancient and free remedy—walking in nature—might offer comparable, and often more sustainable, relief.

As someone who has personally navigated trauma, injury, chronic pain, and grief—and worked as a chiropractor helping others do the same—I’ve found nature-based movement to be a powerful medicine. Let’s explore the science behind both SSRIs and walking in nature, and see how these two approaches compare.

🧠 What Are SSRIs and How Do They Work?

SSRIs are medications that increase the amount of serotonin available in the brain. This neurotransmitter is commonly associated with feelings of well-being and stability. By preventing the reabsorption (reuptake) of serotonin, these drugs can enhance mood in many people—particularly those with moderate to severe depression.

SSRIs can be life-saving for some. They are effective in roughly 30% of patients after initial treatment, according to the landmark STAR*D study. But many users experience diminishing effects over time and require additional medications or adjustments. Moreover, side effects are common and can include:

• Sexual dysfunction

• Emotional blunting or apathy

• Insomnia or fatigue

• Digestive problems

• Weight gain

• Increased suicidal ideation in some age groups

Long-term use also raises concerns about dependency and whether underlying emotional wounds are being addressed or merely numbed.

🌲 Nature as Medicine: The Science Behind Walking

Walking outdoors—especially in green, biodiverse settings—triggers a cascade of healing responses:

• Physical movement boosts endorphins and brain-derived neurotrophic factor (BDNF), both of which support mood and cognition.

• Sunlight enhances vitamin D levels and helps regulate sleep cycles.

• Deep, rhythmic breathing while walking reduces cortisol and stimulates the parasympathetic nervous system (our "rest and digest" mode).

• Grounding (walking barefoot on natural surfaces) may reduce inflammation and improve sleep by helping regulate the body’s bioelectrical systems.

A groundbreaking Duke University study by Dr. James Blumenthal found that after 16 weeks, participants with major depressive disorder who engaged in regular aerobic exercise improved as much as those on Zoloft. At the 10-month follow-up, the exercisers had lower relapse rates than those who took medication alone.

Another 2015 study from Stanford University found that participants who walked for 90 minutes in nature (vs. urban streets) experienced decreased activity in the subgenual prefrontal cortex—a brain region linked with rumination and negative thought loops.

🌞 Comparing the Two Approaches

Aspect	Walking in Nature	SSRIs (e.g., Zoloft, Prozac)
Mechanism	Enhances serotonin, BDNF, endorphins; holistic	Inhibits serotonin reuptake
Side Effects	Minimal to none	Sexual dysfunction, weight gain, fatigue, etc.
Long-Term Benefits	Reduced relapse, increased resilience	Often requires continued use, risk of relapse
Accessibility	Free and natural	Prescription required, often costly
Additional Benefits	Physical health, connection to nature, grounding	Limited to symptom management
Contraindications	Limited mobility or unsafe environments	Certain health conditions, medication conflicts
Emotional Empowerment	Builds self-efficacy and mindfulness	Passive reliance on external intervention

🚶‍♀️ Which Is Better?

That depends. For individuals in acute crisis or severe functional depression, SSRIs can offer a needed bridge. But long-term reliance can have drawbacks, especially if emotional healing and lifestyle shifts aren’t addressed.

Walking in nature—especially when combined with deep breathing, social connection, and intention—offers a resilient and multi-dimensional path to recovery. It addresses root causes: disconnection, stagnation, stress, lack of purpose.

In my own recovery from orthopedic surgeries, grief, and PTSD, nature-based movement has been more potent than any pill. I’ve watched my patients and students—some struggling with addiction, anxiety, and depression—transform through consistent outdoor activity. They reclaim agency, connection, and joy.

💡 Conclusion

If you're struggling with depression, know that you have more than one path. Medication can offer relief, but don’t overlook the healing power of sunlight on your skin, soil beneath your feet, and wind in your lungs. Walking—especially in nature—is not just movement. It’s medicine.

Let’s shift the conversation from "what's wrong with me?" to "what helps me feel most alive?"

If you’d like support starting a trail-based wellness practice, I offer guidance through the TrailFit program—designed to reconnect body, mind, and spirit through nature, rhythm, and movement.

🌿 Reclaiming Your Medicine Walk: How to Begin

If you're new to walking as therapy, begin gently. You don’t need to summit mountains—just step outside your front door with intention.

Here are some starting points:

1. Start small and regular: Begin with 15–30 minutes daily. Choose green spaces whenever possible—parks, trails, beaches, forests, or even tree-lined streets.

2. Breathe deeply: Inhale through the nose, slowly and fully. Feel your belly rise. Exhale through the mouth or nose and lengthen the exhale. This alone can shift your nervous system into calm.

3. Leave the phone behind (or in airplane mode): Let this be time for you, without the pull of notifications.

4. Go barefoot when safe: Grounding on natural surfaces like sand, grass, or soil has been shown to reduce inflammation and improve sleep.

5. Notice, don’t judge: Observe your inner dialogue, your surroundings, your body. Notice patterns, shifts, tensions. You don’t have to fix anything—just witness.

6. Walk with intention: Ask yourself before each walk—What is my body asking for? What emotion wants to move through me? Let the walk be your response.

🌳 Optional Enhancements

• Bring music, drums, or singing into your walk to activate joy and rhythm (especially if depression feels heavy).

• Journal before or after: What am I feeling? What am I releasing?

• Walk with a friend or pet if loneliness is a major theme.

• Join a nature-based movement group (like TrailFit, local hiking clubs, or forest bathing circles).

🌀 Final Thoughts

In a culture that profits off your disconnection, reclaiming nature as medicine is a radical act of self-care. While pharmaceuticals may mute the noise, walking in nature invites us to dance with it—and gradually transmute pain into strength, disconnection into presence.

You are not broken. You are not alone. And you don’t have to heal in a fluorescent-lit room with side effects. The forest, the ocean, the mountains—they are waiting for you, boots off or on, step by step.
