Summary

Evening bright‑light exposure prior to the night shift improved fatigue, work performance, mood, and sleep vs usual conditions.

Why It Matters For Night Shift Workers and Night Owls

This RCT how timing of light, sleep, meals, and schedules showed sleep & alertness and mental health for night‑shift workers and night owls. Overall, the data make the schedule itself visible in physiology, not just in how people feel subjectively. For the audience living on night schedules, the key meaning is that the schedule’s timing choices show up in measurable outcomes.
