“…Bright white light exposure in the morning improved sleep in institutionalized older adults. Fetveit and colleagues [35] demonstrated that exposure to 2 hours of bright light in the morning for at least 2 weeks substantially improved sleep efficiency of older adults living in nursing homes. Alessi et al [36] showed that five consecutive days of 30-minute exposure to sunlight, increased physical activity, structured bedtime, and control of light and noise at night resulted in a significant decrease in daytime sleeping in intervention participants compared to controls.…”

This paper discusses a proposed 24-hr lighting scheme for older adults that can positively impact the aging visual, circadian and perceptual systems. New lighting was installed in eight private rooms in an assisted living facility. Measurements of residents' sleep quality and circadian rest-activity patterns were obtained, before and after the new lighting was installed. Consistent with predictions based upon previous research, the subjects who completed the study showed an improvement in sleep quality and rest/activity rhythms under the new 24-hr lighting scheme. In addition, all study participants reported a strong preference for the 24-hr lighting. The new lighting not only provides older adults with good lighting for performing their routine visual tasks, but also promotes high circadian light stimulation during the day and low circadian light stimulation at night. Although not studied here, but also discussed as part of the 24-hr lighting scheme, is the impact of a previously studied, novel night-light system that provides older adults with enhanced perceptual cues for nighttime navigation within the room. The new 24-hr lighting scheme appears to have important practical implications for improving the quality of life for seniors and will hopefully be adopted by architects, lighting specifiers and engineers.

“…He suggested that the utility of bright light treatment for improving circadian rhythms was a synchronizing factor and that the effects declined with more severe dementia perhaps due to more severe damage to the suprachiasmic nucleus and resultant decreased sensitivity to light. Fetveit et al (2003) administered 2 hours of morning bright light (6000-8000 lux, 8-11 am for 2 weeks) and reported improved nighttime sleep efficiency, decreased nighttime wake time and sleep onset latency. Rest-activity levels also showed decreased nighttime activity and decreased mesor with no change in acrophase.…”

Light, Sleep and Circadian Rhythms in Older Adults With Alzheimer’s Disease and Related Dementias

Alzheimer's disease and related dementias (ADRD) can cause sleep and behavioral problems that are problematic for ADRD patients and their family caregivers. Light therapy has shown promise as a nonpharmacological treatment, and preliminary studies demonstrate that timed light exposure can consolidate and improve nighttime sleep efficiency, increase daytime wakefulness and reduce evening agitation without the adverse effects of pharmacological solutions. Compliance with light treatment and the accurate measurement of light exposures during treatment, however, have presented barriers for the adoption of light therapy for ADRD. Recent research showing that the circadian system is maximally sensitive to short-wavelength light opens the way for the potential application of lower, more-targeted light intensities to maximize compliance and individualize light dose/timing in therapeutic settings.
