If you take a short 15-minute walk through a bamboo forest instead of walking in a city, you might feel more calm and focused afterward, according to how a simple brain-sensing headband measures it.

A randomized crossover trial with 30–50 young adults aged 19–24, each completing two 15-minute walks—one in a controlled bamboo forest setting and one in a matched urban environment—with order randomized and washout period of at least 48 hours. Meditation and attention scores are measured immediately after each walk using the NeuroSky MindWave EEG headset, with self-reporting standardized via validated questionnaires.

A parallel-group RCT with two matched groups of 40 young adults aged 19–24: one group walks 15 minutes in a bamboo forest, the other in an urban setting. Both groups are assessed immediately after using the NeuroSky MindWave EEG headset for meditation and attention scores, with randomization, blinding of assessors, and matching for baseline cognitive and mood states.

An observational study recruiting 100 young adults aged 19–24 who naturally choose to walk either in a bamboo forest or urban environment for exactly 15 minutes. Participants use the NeuroSky MindWave headset before and after their walk, with environmental conditions logged via GPS and environmental sensors. Scores are compared between groups after adjusting for confounders like prior stress, sleep, and physical activity.

A pilot study with 15–20 young adults aged 19–24 who each complete three 15-minute walks: one in bamboo forest, one in urban, and one in a neutral indoor setting, in randomized order. NeuroSky MindWave scores are recorded after each walk, with immediate self-reporting of meditation and attention. Data analyzed for within-subject differences across environments.

A survey of 200 young adults aged 19–24 asking them to recall a recent 15-minute walk in either a bamboo forest or urban area, then report their meditation and attention levels immediately after using the NeuroSky MindWave headset. Environmental context is verified via location data or photo logs.
