Summary

This study tested whether forest therapy—mindful walking, sun bathing, hugging trees, and meditation—could improve symptoms and reduce inflammation in 80 adults with psychotic disorders. Half received forest therapy plus standard care for 8 weekly sessions; the other half received standard care alone. Researchers measured changes in inflammatory markers (CRP, IL-6, BDNF) and symptom scores (PANSS, mood, anxiety, sleep, quality of life).

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Forest therapy (mindful walking, sun bathing, forest hugging, meditation)
What this could lead to: If it works, this could point toward a low-cost, nature-based add-on to standard care for reducing psychotic symptoms and inflammation.
What could go wrong: This is a small, early study (80 people) with no blinding, so results may be influenced by placebo effects. The intervention is behavioral, not a drug, so any benefits are likely modest and may not generalize.
