Forest Bathing for Cancer Patients: How Nature Nurtures Healing, Resilience, and Wellbeing

In a world where medical treatments are often fast-paced, clinical, and isolating, many cancer patients are seeking complementary practices that address the emotional, spiritual, and mental toll of a diagnosis. One increasingly recognized method is forest bathing, also known by its Japanese name shinrin-yoku—a therapeutic, mindful immersion in nature.

While it may sound poetic, the science and impact behind forest bathing are profound. For individuals navigating breast cancer or other types of cancer, forest bathing offers a grounded, evidence-based approach to holistic healing that supports the body, mind, and spirit.

What Is Forest Bathing?

Forest bathing (shinrin-yoku) originated in Japan in the 1980s as a public health initiative to counteract the negative effects of technology, urbanization, and work-related stress. Unlike hiking or jogging, forest bathing is not exercise—it’s the act of mindfully experiencing the forest through your senses.

You slow down, breathe deeply, and intentionally observe the sights, sounds, textures, and smells of your surroundings. You may sit quietly in a “sit spot,” walk slowly, or engage in gentle guided meditations. There’s no destination—only presence.

Studies conducted by Dr. Qing Li, a physician at Tokyo’s Nippon Medical School and one of the world’s leading researchers in forest medicine, show that forest bathing:

• Reduces cortisol (a stress hormone)

• Lowers blood pressure and heart rate

• Improves sleep and concentration

• Boosts immunity by increasing natural killer (NK) cells, which help fight cancer

• Reduces anxiety and depression symptoms

  
  

For cancer patients, these benefits are especially meaningful.

Why Forest Bathing Matters for Cancer Patients

Receiving a cancer diagnosis is life-altering. Whether you're managing chemotherapy side effects, navigating post-surgical recovery, or living with metastatic disease, the emotional burden can be heavy.

Forest bathing offers a restorative pause. As many cancer survivors on the Breast Cancer Conversations podcast have shared, nature provides more than a backdrop—it becomes a partner in healing.

Here’s how:

• Reduces Stress and Anxiety

  Cancer treatment often brings persistent stress, which can weaken the immune system and worsen fatigue. Forest bathing lowers cortisol and helps regulate the nervous system, supporting a calm, parasympathetic state where the body can rest and repair.

• Boosts Immune Function

  One of forest bathing’s most compelling benefits is its ability to enhance immune defense. When we breathe in the forest air, we’re also inhaling phytoncides—natural essential oils released by trees to protect themselves from bacteria and insects. These compounds stimulate the production of natural killer (NK) cells, which are crucial in the body’s fight against infections and tumor cells. In Dr. Li’s research, participants who engaged in two days of forest bathing had increased NK cell activity for up to 30 days post-visit.

This is especially promising for people with compromised immunity during chemotherapy or immunotherapy.

A Mind-Body-Spirit Approach: Forest Bathing as Holistic Healing

Forest bathing isn’t just a physiological practice—it reconnects us to something deeper: meaning, presence, and purpose.

For many cancer patients, diagnosis can prompt a spiritual crisis. The podcast guest from the Breast Cancer Conversations episode titled “Nature’s Healing Fosters Human Connection” described how forest bathing allowed her to reconnect with the wholeness of her identity beyond diagnosis.

She shared how the trees felt like witnesses—offering silent companionship when she needed it most.

“When I couldn’t recognize myself in the mirror after surgery, the forest reminded me who I was. There was no judgment there, just stillness and love.”

This relational quality of nature—where individuals feel seen and supported—is a hallmark of forest therapy’s healing potential.

How to Practice Forest Bathing During or After Cancer Treatment

Whether you live near a lush forest or an urban park, forest bathing is accessible to nearly everyone. You don’t need hiking gear, stamina, or a guide—just willingness and time.

Here’s a step-by-step guide to get started:

1. Choose Your Space

• Local forest preserve, botanical garden, park, or even your backyard

• Look for spaces with trees, gentle paths, and minimal noise

2. Leave Devices Behind

• Unplug to fully engage your senses

• Avoid distractions like headphones or podcasts

3. Slow Down and Tune In

• Begin with deep, slow breaths

• Use your senses:

  • Sight: Watch how light filters through leaves

  • Smell: Inhale the earthy, piney air

  • Sound: Listen to birds, wind, and rustling leaves

  • Touch: Feel the texture of bark or moss

  • Taste: Bring a herbal tea or simply savor clean air

4. Use the S.O.A.R. Method

A common forest therapy guide acronym:

• Settle – Physically arrive and breathe

• Open – Let go of distractions

• Attune – Tune in to surroundings

• Receive – Notice what nature offers you

5. Reflect (Optional)

• Journal your experience

• Note any thoughts, feelings, or sensations

• Share with a support group or therapist if helpful

  
  

Adapting Forest Bathing for Accessibility

For patients who are immunocompromised, fatigued, or have limited mobility, virtual forest bathing or indoor nature immersion are effective alternatives.

Ways to bring nature inside:

• Nature sound recordings (waterfalls, birdsong, wind)

• Live houseplants or fresh flowers

• Nature videos or forest-view screensavers

• Essential oils like pine and cedarwood

You can also:

• Sit by a window and observe trees or the sky

• Touch natural objects like stones, leaves, or shells

• Create a dedicated “nature corner” at home with calming objects

  
  

What the Research Says: The Science Behind Forest Bathing and Healing

Here are some additional evidence-based insights:

• A 2010 study in the International Journal of Immunopathology and Pharmacology showed that forest bathing significantly increased NK activity and anti-cancer proteins in women with breast cancer.

• A 2020 Korean study found that just 90 minutes of forest exposure decreased cancer-related fatigue and improved mood in patients undergoing chemotherapy.

• A 2019 review in Frontiers in Psychology concluded that forest bathing is a powerful tool for trauma recovery, emotional regulation, and spiritual integration—making it ideal for post-diagnosis survivorship support.

Nature Is Not a Luxury—It’s a Lifeline

Forest bathing is far more than a wellness trend; it’s a scientifically backed, soul-nourishing practice that reminds us of who we are beneath the layers of stress, illness, and expectation. For cancer patients and survivors, it provides something that’s often missing from conventional treatment: a space for emotional safety, self-reflection, and spiritual renewal.
