A study published in Health Education & Behavior is the first to confirm a positive link between nature exposure and physical activity in adolescents using objective, continuous, individual-level measures. Researchers recruited 202 teens (ages 12–17) in the Eugene/Springfield, Oregon area and equipped them with NatureDose®—an app developed by NatureQuant that passively tracks time spent in and near nature—alongside wrist-worn accelerometers over seven days. On days when adolescents spent more time in nature, they also logged significantly more moderate-to-vigorous physical activity (MVPA), even after accounting for age, gender, BMI, and socioeconomic factors. The study found no significant association between nature exposure and body appreciation, but the nature-to-activity link was robust and consistent across participants. These findings support integrating natural environments like parks and trails into adolescent physical activity interventions.
