This study aims to test the associations of nature contact with multiple dimensions of psychological functioning. A total of 90 university employees were randomly assigned to spend their lunch breaks on (1) a 30-min structured protocol of nature contact and (2) a control group for 10 consecutive weekdays. Psychological distress, psychological well-being, and work-related psychological outcomes were assessed at baseline (T1), the day after the 10-day intervention (T2), and three months after the intervention (T3). Mixed-design analyses of variance (ANOVA) were conducted. Overall, significant intervention effects were found in the structured protocol of nature contact on psychological distress, well-being outcomes, and work engagement (all p < 0.05), whereas the 3-month post-intervention effects were non-significant. Our study showed that nature-based activities during lunch breaks could enhance office workers’ mental health in general, but the effects could be short-lived, calling for regular nature-based programs in occupational settings.
