Roger Ulrich's well-known research showed that patients recovering from surgery used fewer pain-reducing medications when in a hospital room with a view of trees rather than a view of a building.
The experiment we conducted also examined the role of plants in pain perception.
We found that more subjects felt discomfort from a hand submerged in ice water if they were in a room without plants than if they were in a room with plants.
This was true even if the room without plants had other colorful objects that might help people get their minds off of the discomfort.
Results from a room assessment confirmed that the control room with non-plant objects was as interesting and colorful as the room with plants, but the presence of plants was perceived as making the air in the room fresher.
