Effects of Indoor Plants in the Reduction of Stress Abigail, Anastasya; Kang, Jonathan; Durnford, Kody; Liu, Michelle; Parker, Oliver


A correlational, between-subjects design was done in order to further investigate the positive effect that indoor plants have on stress in the UBC campus. The present study makes an initial attempt to evaluate the potential benefits of placing indoor plants in pocket lounges in the Nest, which are areas that students often use to either rest or study. A Profile of Mood States survey, that included other demographical questions, was administered to approximately 52 students who were present in the pocket lounge at the time when the experiment was conducted. Data were analyzed to compare the levels of stress, operationalized by measures of mood, before and after plants were added to the room. The findings suggest no significant (P > 0.05) decrease in the level of stress that students have even with the addition of various plants. The results show a minor decrease in the following items ranked in the survey, although other variables and confounds, such as timing and change blindness, may have affected the plant’s effect on the individual’s stress level. Overall, no differences were found between independent items in the survey, nor were they found in the comparisons between both conditions.
