Shift Work Light Exposure Timing
Shift work light exposure timing pairs bright light on shift with darkness before day sleep—sunglasses and blackout block morning sun that fights melatonin.
Shift work light exposure timing uses bright light when you need alertness on shift and darkness before daytime sleep—often bright workplace or lamp during night hours, then sunglasses and blackout after. Wrong timing—sun on the drive home or phone in bed—shifts melatonin against your goal.
Light therapy doses follow rotation direction under guidance.
Common questions
-
Should night workers get morning sun?
Usually minimize morning sun after night shifts—it advances circadian phase when you need to sleep days. Use bright light during the night wake period instead, matched to your rotation plan.
