Nancy Etcoff, Ph.D., of Massachusetts General Hospital and Harvard Medical School and her research team investigated the effects of flowers in the home environment on well being. Fifty-four people, ages 25-60, were studied using a series of self-report measures allowing the research team to know where the person was, with whom and what they were doing when they experienced an emotion, both when flowers were and were not present. Half of the participants received a “control” home décor item, other than flowers, to ensure study validity. After living with either flowers or the control intervention for approximately one week, participants rated their feelings during specific periods of the day, recording emotions during each episode. The research team also took photographs before and after flowers were delivered to determine any changes in use or appearance of the room.
