Outdoor night light exposure and sleep structure, a panel study using consumer-grade wearables
This study suggests that moderate NTL levels are associated with slightly longer light sleep durations, whereas higher NTL levels may negatively impact deep sleep. The findings stress the need for urban lighting guidelines that balance safety with sleep health, minimizing negative effects on circadian rhythms. This research also contributes to future studies on personalized light exposure, considering indoor factors and individual sleep behaviors.
