Growing research confirms what many intuitively know: time in nature measurably reduces post-traumatic stress disorder. The mechanisms are multiple and the effects are significant.
The Science of Nature and Post-Traumatic Stress Disorder
Research demonstrates that exposure to natural environments affects post-traumatic stress disorder through:
- Attention Restoration Theory: Nature provides effortless attention that rests the directed attention depleted by stress and post-traumatic stress disorder
- Stress Recovery Theory: Natural environments reduce physiological stress markers faster than urban environments
- Phytoncides: Chemical compounds from trees reduce cortisol levels
- Negative ions: Higher concentrations near water and forests affect serotonin
Types of Nature Therapy for Post-Traumatic Stress Disorder
Forest Bathing (Shinrin-yoku): Slow, mindful immersion in a forest environment — demonstrated effects on cortisol, blood pressure, and mood in post-traumatic stress disorder.
Blue space: Water environments (ocean, lakes, rivers) produce distinct wellbeing benefits for post-traumatic stress disorder.
Green exercise: Combining outdoor movement with nature enhances both exercise and nature benefits for post-traumatic stress disorder.
How Much Nature Time for Post-Traumatic Stress Disorder?
Research suggests 120 minutes per week in nature is associated with significantly better mental health. This can be two 1-hour walks or shorter daily exposures. Even urban parks count.
