Adding plants to a windowless computer lab made participants 12% quicker on a timed computer task
In a study set in a windowless college computer lab, the presence of indoor plants was associated with a 12% improvement in reaction time on a timed computer task, suggesting a meaningful boost to productivity in otherwise sterile work environments.
When plants were added to this interior space, the participants were more productive (12% quicker reaction time on the computer task) and less stressed (systolic blood pressure readings lowered by one to four units).
