Background Perceived stress in the workplace is a growing concern, with modern office environments often contributing through noise, crowding, and lack of privacy. To support office workers' well-being and recovery during the workday, new ways of working-such as spending time outdoors-are being explored.Objective This explorative pilot study aims to investigate whether engaging in at least 30 min of outdoor office work each day for five consecutive working days could reduce self-rated stress levels among office workers.Methods A within-subjects design was employed. During the first week, eight participants followed their regular office routine. In the second week, the same participants were instructed to spend a minimum of 30 min each day performing office work outdoors.Results In the second week, participants worked outdoors for an average of 322 min per week (approximate to 64 min/day), primarily in urban nature settings. Self-rated stress levels were 15% lower than in the first week, a statistically significant reduction by paired-sample t-test, though not by the Wilcoxon test.Conclusions Daily outdoor work is feasible among office workers and may reduce self-rated stress levels, warranting larger studies with more diverse participants and environments.
