Lighting Has ‘Profound Impact on Older Adults’

. . . especially those with Alzheimer’s, according to new information from Abe’s Garden.

According to the study, typical institutional light levels are not high enough during waking hours or tuned to the correct color to activate the circadian system in elderly people, often resulting in sleep disruption. This disruption causes changes in sleep patterns, confusion in daily routines, decreased alertness, and mood alteration resulting in feelings of depression.

Abnormal sleep patterns tend to increase with the progression of Alzheimer’s disease and related dementias (ADRD) and are associated with aggressive behavior and caregiver stress.

To improve the health and quality of life for individuals with ADRD, Figueiro recommends a 24-hour lighting scheme designed to provide high circadian stimulation during the day, low circadian stimulation at night, good visual conditions during waking hours, and nightlights that are safe and minimize sleep disruption.

ADRD disrupts higher cognitive processes and may result in significantly greater balance and coordination issues, increasing an individual’s risk for falls.

Lighting modifications may reduce the risk of falls, especially at night, when light levels are low.
