Summary

This study aims to investigate the effect of a dynamic lighting intervention on sleep quality, circadian activity rhythms, and mood in older adults with dementia living in long-term care facilities. The dynamic lighting intervention is designed to create an ambient illumination that provides a high level of circadian stimulation in the morning and circadian-neutral lighting in the evenings through delivering varying light intensity and spectrum.

Interventions

OTHER

Dynamic Lighting

This will be an eighteen-hour lighting scheme that includes three modes: morning (6:00 - 12:00), afternoon (12:00 - 18:00), and evening (18:00 - 24:00). It mimics natural lighting by providing blue-enriched high-intensity lighting in the morning and neutral white medium-intensity lighting in the afternoon to maintain alertness without exerting substantial circadian effects. The biodynamic lighting will provide yellowish low-intensity lighting in the evening to minimize any circadian effect.

OTHER

Placebo Lighting

We will include an active placebo condition that will be a whole-day lighting scheme with constant color and brightness from morning to evening. The numbers of CCT and illuminance levels are selected based on the average room lighting
