Summary
This study examines how repeated morning bright white light exposures affect attention performance in a simulated office setting, with particular attention to the role of ipRGCs in sustained alerting responses. The findings have practical implications for designing office lighting protocols that optimize daytime alertness and cognitive performance through targeted morning light interventions.
Key Findings
- Repeated morning bright white light exposures were associated with improvements in attention in a simulated office environment.
- ipRGCs were noted to show prolonged firing even after light offset, suggesting sustained non-visual effects of morning light exposure beyond the exposure period itself.
