Investigators have found that varying lighting in nursing homes during the course of the day, so that light intensity and color mimics lighting conditions outdoors, supports better sleep among residents. Baier, Miller, McCreedy, Uth, Wetle, Noell-Waggoner, Stringer, and Gifford, used data collected from study participants with an average age of 88 to better understand sleep related issues among nursing home residents: “Nursing home residents tend to fall asleep at all hours of the day, and during the night, their sleep may be interrupted by periods of wakefulness. . . . [at] one California nursing home. . . . [in a dynamic lighting condition] the facility installed interior [LED] lighting fixtures that change color and intensity over the course of the day and night [to mimic natural light]. . . . The tuned lighting brightened corridor lighting in the day and dimmed it during the night. The static condition mimicked the fluorescent lighting in place at the facility prior to installation of the tunable fixtures. . . . The study found that, on average, the residents experienced 3.6 nighttime sleep disturbances with static lighting compared to 1.8 with tuned lighting.” Findings are published in Seniors Housing and Care Journal.
