  • Light exposure in real-world settings influences cognitive performance, including subjective sleepiness, vigilance, and working memory.
  • Higher daytime light exposure and reduced fragmentation of light exposure patterns are linked to improved cognitive performance.
  • Recent bright light exposure correlates with lower sleepiness scores and faster reaction times in cognitive tasks.
  • Individuals with earlier bedtimes and brighter daytime light exposure show stronger associations between light exposure and reduced sleepiness.
  • The study found no strong associations between in-lab measures of light sensitivity and real-world cognitive performance.
  • Habitual light exposure patterns, such as brighter and more stable daytime light, are associated with better cognitive outcomes.
  • The research highlights the importance of personalized light exposure strategies to enhance cognitive performance and well-being.
