Nature prescription: can outdoor time ease student stress?
NCT ID NCT06633367
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looked at whether encouraging college students to spend more time outdoors improves their mental health. Over 1,500 students aged 18-24 from multiple universities, including historically Black and Hispanic-serving institutions, took part. Researchers measured distress, worry, and mood to understand how nature exposure can help address the youth mental health crisis.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- increasing time in nature
- What this could lead to
- If successful, this could show that simple nature exposure programs improve mental health and reduce disparities among college students.
- What could go wrong
- This is a completed observational study, not a treatment trial. Results may not apply broadly, and the intervention is minimal (encouraging outdoor time).
