Lighting Levels in the Dwellings of Homebound Older Adults

Although poor lighting in the dwellings of older adults has been associated with falls, depression, and reduced visual performance, there has been little measurement of actual light levels in their homes. Knowing the interior light levels and preferences of older adults, especially the homebound, will be of value to service providers and designers in targeting effective interventions. This pilot study measured light levels in the apartments of 40 homebound older adults in New York City, and compared them with industry standard minimum light levels. Nearly all participants had inadequate light levels, yet rated their lighting conditions as adequate. Further research is needed on optimal light levels for improved health, safety, and quality of life.
