Taking a short 15-minute walk among bamboo trees might help young adults feel less anxious than taking the same walk in a busy city.

A randomized controlled trial where young adults aged 19–24 are randomly assigned to either a 15-minute walk in a bamboo forest or a 15-minute walk in an urban environment, with state anxiety measured using a validated scale (e.g., STAI-S) immediately before and after each walk, with a washout period between conditions to avoid carryover effects.

A repeated measures study where each participant completes both a 15-minute walk in a bamboo forest and a 15-minute walk in an urban environment on separate days, with state anxiety measured before and after each walk using a standardized tool, and the order of environments randomized.

An observational study comparing state anxiety levels in young adults aged 19–24 who naturally choose to walk in a bamboo forest versus those who walk in an urban environment, with anxiety measured immediately after the walk.

A survey-based study asking young adults aged 19–24 to recall recent walks in bamboo forests or urban areas and report their anxiety levels immediately after those walks.

Anecdotal reports from individuals describing reduced anxiety after a 15-minute walk in a bamboo forest compared to urban walks.
