There are many health benefits to having plants in the house or office, including decreasing stress. Occupants of the room or office feel more at ease and relaxed. Office workers are happier and take fewer sick days than work environments without plants.
Hospital patients benefit from plants because they ease their stress and turn their focus away from their medical conditions. Plants also improve air quality, decrease background noise, reduce carbon dioxide levels, reduce levels of pollutants and airborne dust, increase humidity, and help to keep temperatures down.
