Story summary
- NC State researchers found that 106 students in a forest with birdsong recorded the lowest stress scores.
- The forest-birdsong pairing averaged a stress score of 3.2, versus 6.4 for the plaza-traffic pairing.
- Both the green setting and the birdsong each lowered stress and improved emotions.
- Cindy Frantz warned that a single study cannot confirm benefits, though the 2006 forest with over 70% canopy shows green spaces can aid health.
