What Is Forest Bathing?
Forest bathing, or Shinrin-yoku, originated in Japan in the 1980s as a response to rising urban stress and lifestyle-related illnesses. The term was first coined by the Japanese Ministry of Agriculture, Forestry, and Fisheries to encourage people to reconnect with nature for their overall well-being. It literally translates to “taking in the forest atmosphere” through all five senses, and it soon became integrated into preventive health programs across Japan. Studies such as this pilot research on post-COVID mental health and broader urban greening research have helped validate its therapeutic relevance across different populations. (1) (2) The practice has since spread globally and is now incorporated into public health systems, wellness tourism, and clinical psychology.
At its core, forest bathing is not about hiking or exercising but about mindful immersion in nature. The key principles include moving slowly, staying present, activating the senses, and disconnecting from technology. Research highlights how visual and olfactory exposure to forests significantly reduces stress markers, and phytoncide-rich environments are linked to improved immune function. (3) Additional studies have shown forest bathing lowers cortisol, stabilizes heart rate, enhances mood regulation in students, and even supports rehabilitation in vulnerable populations. (4) (5) (6) (7) These effects collectively underscore why forest bathing is now viewed as a credible nature-based intervention for mental and physical health.

The Science behind It: How It Calms the Mind
Forest bathing, or Shinrin-yoku, is a mindful practice of immersing yourself in nature. Backed by science, it reduces stress, lowers cortisol, and enhances mental clarity through sensory and physiological engagement.
Forest bathing significantly enhances parasympathetic nervous system (PNS) activity, which promotes a “rest-and-digest” physiological state essential for mental recovery. Visual and olfactory exposure to forest stimuli has been shown to lower heart rate variability and increase vagal tone, both markers of PNS activation. (3) Studies on guided forest therapy confirm its capacity to calm autonomic responses and balance nervous system activity. (8) (9) Additional evidence suggests forest stimuli reduce sympathetic arousal and boost emotional regulation through vagal engagement. (10) (11)
2. Reduces Cortisol Levels (Stress Hormone)
Forest bathing has been shown to significantly reduce cortisol, a primary biomarker of psychological stress. Engaging in natural environments leads to marked reductions in salivary cortisol levels, indicating physiological stress recovery. (12) Controlled trials confirm that forest walking reduces cortisol more than urban walking. (5) Biophilic exposure in natural settings elicits hormonal relaxation and promotes mood stability. (13) (14) A systematic review also supports forest bathing’s influence on stress biomarkers across age groups. (15)
3. Enhances Mood and Emotional Regulation
Forest bathing has consistently been shown to enhance mood and emotional stability through sensory immersion and mindfulness. Participants report decreased anxiety and increased positive affect following even brief exposure to forested environments. (9) The practice fosters emotional resilience in youth and students and aids recovery in long-COVID patients. (2) (1) Self-regulation and self-compassion also improve during guided forest walks. (10) Multisensory elements of forests have even been integrated into therapeutic interventions for mood disorders. (16)
4. Stimulates Positive Neural Activity
Forest bathing activates neural circuits that enhance emotional stability and attentional control. Research shows it decreases amygdala activity, which is involved in processing stress. (17) A one-hour walk in a natural setting significantly reduced neural activity in this stress-related region. Simultaneously, positive effects have been observed in the prefrontal cortex, a region tied to mood and executive function. (18) Participants exposed to forest environments showed increased frontal lobe activation. (16) Green exposure also correlates with higher frequency oscillations linked to calm, reflective states. (19) These findings support the neural benefits of forest immersion as both therapeutic and preventative.
5. Boosts Immune System Function via Phytoncides
Forest bathing strengthens the immune system by increasing the activity of natural killer (NK) cells, key to defending against infections and tumors. This is largely due to phytoncides—antimicrobial volatile organic compounds emitted by trees. A 2024 meta-analysis confirmed increased NK cell count after forest exposure. (20) Additional studies show that forest air enhances lymphocyte activity and modulates immune markers positively. (5) (21) Other research reveals forest therapy increases interleukin-6 regulation and improves mucosal immunity. (2) (14)
6. Improves Sleep and Reduces Fatigue
Forest bathing is linked to better sleep quality and reduced fatigue through its calming sensory and hormonal effects. Elderly participants showed improved restfulness and decreased sleep latency after forest sessions. (11) Other studies observed reduced occupational fatigue in various workgroups and lowered burnout-related exhaustion. (22) (23) Forest exposure is also effective for long-COVID fatigue recovery and enhancing relaxation and mood-regulated sleep. (10) (2)
7. Promotes Cognitive Recovery and Mental Clarity
Forest bathing restores attention and cognitive capacity through exposure to calming natural stimuli. It supports Attention Restoration Theory (ART) by reducing directed mental effort and promoting involuntary attention, leading to clearer thinking and focus. (24) Studies in students and elderly show enhanced mental clarity and reduced mental fatigue. (4) (1) Forest silence improves perceived time flow and relaxation, while green exposure boosts executive function and neural connectivity linked to memory. (10) (25)
8. Strengthens Self-Compassion and Lowers Self-Criticism
Forest bathing has a therapeutic impact on self-perception, enhancing self-compassion and reducing critical inner dialogue. A 2024 systematic review confirmed its efficacy in lowering self-judgment and increasing self-protection behaviors. (10) Research among university populations revealed improved self-kindness and emotional regulation. (1) Green immersion improves reflective processing, reduces shame, and supports recovery from internalized trauma. (22) (26) Forest sessions also correlate with increases in self-acceptance and emotional safety. (27)
9. Helps Manage Hypertension in Older Adults
Forest bathing has demonstrated significant benefits for managing hypertension, particularly among the elderly. Immersive forest experiences reduce both systolic and diastolic blood pressure through enhanced parasympathetic activity and reduced stress. (11) Studies show measurable improvements in hypertensive patients after repeated sessions and confirm positive cardiovascular effects from forest air and scenery. (28) (29) Further trials note forest therapy’s ability to stabilize blood pressure across age groups and improve outcomes in geriatric patients with chronic hypertension. (30) (4)
How to Try Forest Bathing
Trying forest bathing is simple and rewarding. It involves immersing yourself in nature, engaging your senses, and slowing down. No special gear—just mindful presence in a peaceful, natural environment.
Choosing an appropriate natural setting enhances the physiological and psychological benefits of forest bathing. Research shows that biodiverse, tranquil forests promote greater reductions in cortisol and heart rate. (31) Dense canopies and natural sounds are vital for relaxation. Even urban green spaces offer measurable effects when carefully selected.
2. Set Aside Uninterrupted Time
Dedicating undisturbed time enhances forest bathing’s restorative effects. A study suggests that at least 120 minutes weekly in nature correlates with improved well-being. (32) Uninterrupted immersion allows deeper sensory engagement and parasympathetic activation. (33) Even short, focused exposure improves attention and mood.
3. Leave Devices Behind
Disconnecting from digital devices enhances mindfulness and strengthens the restorative impact of nature. Studies show that reduced screen exposure boosts mental clarity during forest immersion. (34) Digital detox also supports lower sympathetic nervous system activity. Attention restoration occurs more effectively without tech distractions.
4. Walk Slowly and Aimlessly
Slow, aimless walking amplifies sensory engagement and encourages present-moment awareness. Research confirms it leads to improved mood and reduced anxiety compared to structured exercise. Such unhurried movement promotes deeper physiological relaxation. (35) The open-ended wandering aligns with the meditative essence of forest bathing.
5. Use All Your Senses
Engaging all five senses during forest bathing enhances therapeutic effects. Scent exposure from trees improves immune function through phytoncides. (31) Auditory cues like birdsong reduce stress and anxiety. Visual immersion in greenery also boosts attention and cognitive recovery.
6. Sit and Be Still
Sitting in stillness during forest bathing deepens parasympathetic activation and emotional regulation. Research shows stationary immersion leads to lower cortisol levels than walking alone. (36) Quiet observation fosters mindfulness and enhanced sensory detail. Longer sitting intervals are linked to stronger physiological restoration.
7. Reflect Gently (Optional)
Gentle reflection after forest bathing enhances self-awareness and emotional balance. Journaling or sketching consolidates nature’s calming effects, aiding cognitive integration. (37) Reflective practices amplify perceived restoration and resilience. Even short mindfulness-based reflection improves psychological flexibility post-immersion.
8. Stay Hydrated and Comfortable
Staying hydrated and dressed appropriately enhances the experience and prevents physical stress. Dehydration can impair cognitive function during prolonged exposure. (38) Comfortable attire reduces thermal stress and supports physiological relaxation. Proper preparation increases engagement and time spent in nature, amplifying forest therapy benefits. (32)
9. Practice Regularly
Consistent forest bathing maximizes its long-term benefits. Weekly or bi-weekly exposure sustains reduced anxiety and elevated immune markers. (31) Routine visits deepen the physiological response, including lowered blood pressure and heart rate. (39) Regularity builds emotional resilience and cognitive clarity over time.
10. Respect Nature
Respecting natural environments ensures the sustainability of forest bathing practices. Leaving no trace protects biodiversity and ecological integrity. (40) Ethical engagement with nature enhances the sense of connection and responsibility. Responsible behavior reinforces the therapeutic loop between human well-being and environmental stewardship.
