An infographic illustrating the effects of houseplants on mood and productivity over the course of two days. This demonstrates the effect of continual plant exposure versus the absence of a plant companion with the average college student.
Each subject was required to record their feelings each hour, along with their activities and inner reflections or thoughts. On the first day, the subject was not to interact with any type of indoor plant. On the second, the subject was required to remain in the presence of a house plant.
House plants were assigned to participants based on personal preference.
