Forest activities showed emotional gains, with no clear added benefit from therapist guidance
Graduate students showed larger short-term emotional improvements in forest than urban settings, but guided forest activities did not show statistically superior results.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Among these graduate students, short outdoor activities were followed by fewer negative emotions, and forest exposure showed greater improvement than urban exposure. Adding a forest therapist did not produce a statistically superior result. That finding leaves uncertainty about the value of guidance; it does not establish that guided and unguided activities are equivalent.
The abstract omits sample size, allocation methods, numerical effect estimates and longer follow-up. This abstract-based account cannot establish lasting stress reduction or assess the authors’ cost-effectiveness claim.
What researchers found
Negative emotional states with therapist guidance
After brief forest exposure, therapist-guided activities did not show statistically superior emotional benefits over unguided exposure; effect sizes were not provided.
Setting and guidance
The study asked whether setting and guidance changed short-term emotional responses. It examined negative emotions including tension, low mood, anger, fatigue and confusion, with reductions reported across every outdoor-activity group.
Environmental differences remain unexplained
Forest settings were also described as quieter and higher in negative air ions. Those accompanying environmental differences do not establish which feature explained the emotional results, or whether any changes persisted.
