Summary
This study investigates how human-centric lighting (HCL) parameters can be optimized to address the specific visual and biological needs of older adults, who experience reduced light sensitivity and higher rates of sleep dysfunction, depression, and cognitive impairment. Findings provide practical guidance for designing lighting environments in elder care settings that support cognitive function and overall wellbeing.
Key Findings
- Human-centric lighting parameters were found to meaningfully influence cognitive performance outcomes in older adults, though specific effect sizes are not available from the abstract alone.
- Older adults face compounded risks from age-related changes in photoreception and circadian regulation, underscoring the need for tailored lighting interventions in senior living and care environments.
- The study highlights the importance of tuning illuminance levels and spectral qualities of light to compensate for the reduced light transmission through aging ocular media.
