Fight the clock mismatch with light and darkness as tools: bright light early in the night shift, sunglasses on the drive home, a blacked-out cool bedroom, and a long nap before the shift - the moves NIOSH research supports.
Time caffeine to the first half of the shift only, and keep the same sleep-wake times even on days off when possible - schedule-bouncing is the hardest version on the body. Persistent insomnia or crushing sleepiness tied to the schedule is shift work disorder, a real and treatable diagnosis.

Common questions
How do shift workers sleep better?
Shift work fights biology: your body clock wants sleep at night and alertness in daylight, and the job demands the reverse - so the strategy is to move the clock and protect the sleep window deliberately. The evidence-backed moves, per NIOSH research: use light as a drug - bright light exposure early in the night shift tells the brain it is day, and sunglasses on the commute home prevent morning light from resetting you awake; black out the bedroom completely - blackout curtains or a mask, cool temperature, and earplugs or white noise, with the phone off and a household agreement on quiet hours; nap strategically - a long nap (NIOSH cites one) before a night shift banks sleep ahead of the debt; time caffeine to the first half of the shift only; and keep the same sleep-wake times even on days off when possible, since bouncing between schedules is the hardest version on the body. Watch for shift work disorder: persistent insomnia or excessive sleepiness tied to the schedule is a real, treatable diagnosis.
