Your daytime sleep window, built from your shift times.

Optional pre-shift nap

Running a split schedule, or short on sleep today? A 90-minute nap from 7:30 PM to 9:00 PM (ending an hour before your shift) measurably reduces sleepiness during the 3–5am alertness trough.

Circadian anchor

Try to keep your wake time within 2 hours of 2:00 PM on days off. Drifting by more than 2 hours creates "social jet lag", your worst enemy on night shifts.

Light management

Wear blue-light-blocking glasses or dim your environment after 5:00 AM to signal your body it's time for sleep. Expose yourself to bright light immediately after waking at 2:00 PM to anchor your circadian rhythm.

Tips for better shift sleep

Blackout curtains are essential, even brief light exposure during your sleep window suppresses melatonin and fragments sleep.

Maintain your sleep schedule on days off. Sleeping in to a daytime schedule and flipping back each week is the worst pattern for circadian health.

Melatonin (0.5–3mg) taken 1 hour before sleep start can help anchor your sleep window. Consult your doctor for personalised advice.

Life Situations

Night Shift Sleep Schedule

For a typical night shift, the best schedule is sleeping roughly 7am to 2pm, starting within an hour of getting home, and holding it on days off. Enter your shift times for a personalised sleep window, 7-day plan, and light timing.

The default night shift sleep schedule

The schedule that works for most permanent night workers is simpler than the advice industry suggests: finish your shift, get home with as little bright light exposure as possible, and be in bed within about an hour, typically a 7am to 2pm sleep window for a 10pm to 6am shift. That window is not arbitrary. Melatonin remains elevated into the morning regardless of your work schedule, so morning sleep captures part of your biological night. Afternoon sleep does not, which is why "I'll sleep after lunch" schedules feel so much worse.

The calculator above builds this window from your exact shift times and adds the two highest-leverage details: when to stop bright light before bed (about two hours out) and when to seek it after waking, which anchors your circadian clock to the schedule instead of fighting it.

Single block vs. split sleep

A single consolidated block is the default recommendation because it maximises deep sleep and REM continuity. But split sleep has real evidence behind it for night workers: a main morning block of 5 to 6 hours plus a 60 to 90 minute nap in the early evening, ending an hour or more before the shift starts. The pre-shift nap reduces on-shift sleepiness during the 3 to 5am alertness trough, the window where most night-shift errors and drowsy-driving incidents cluster.

Pick the pattern you can actually repeat. An imperfect schedule kept seven days a week beats a perfect schedule kept four.

Coming off your last night shift

The transition back to daytime living is where most schedules fall apart. The evidence-based pattern: after your final night shift, take a shortened morning sleep (3 to 4 hours rather than a full block), get up in the early afternoon, stay active in daylight, and go to bed at a near-normal evening hour that night. One shortened sleep produces enough pressure to re-anchor you to a night schedule in a single day, rather than drifting for three.

Days off: hold the anchor

Fully flipping to a daytime schedule on days off and back again each week is the single most disruptive pattern in shift work, functionally a weekly long-haul flight. If staying nocturnal on days off is not realistic, hold a fixed 4-hour core (for example, always asleep 7am to 11am) and flex the rest. A partial anchor preserves most of the adaptation you have built; a full flip resets it to zero.

The Shift Work Sleep Calculator handles evening and rotating patterns, including forward and backward rotation transitions. After a run of nights, the Sleep Debt Calculator shows what the run cost you and how long recovery takes, and the Caffeine Calculator finds the latest dose time that will not sabotage your morning sleep.

Working a named rotation? There are dedicated sleep guides for the 4 on 4 off schedule, the Panama 2-2-3 schedule, and the DuPont schedule.

Frequently asked questions

What is the best sleep schedule for night shift?
For a typical 10pm–6am or 11pm–7am night shift, the most sustainable schedule is a single sleep block starting about an hour after you get home, roughly 7am to 2pm, kept the same every day including days off. Morning sleep works better than afternoon sleep because it still overlaps the tail of your biological night, when melatonin is elevated. The calculator on this page adjusts the window to your exact shift times.
How should I sleep after a night shift?
Get to bed as soon as practical after your shift, ideally within about an hour, before the morning circadian alerting signal builds and makes falling asleep harder. On the commute home, keep light out of your eyes (sunglasses or blue-blocking glasses help); at home, use blackout curtains, keep the room cool, and silence the phone. If a single block does not work for you, a split pattern (a main morning block plus a 90-minute nap before your next shift) is a legitimate, research-supported alternative.
Is it better to sleep in one block or split sleep on nights?
Both work, and the honest answer is whichever you can keep consistent. A single 7-hour morning block gives the most consolidated sleep. A split schedule (for example 8am–1pm plus a 90-minute nap at 8pm before the shift) suits people whose sleep fragments in the afternoon anyway, and the pre-shift nap measurably reduces on-shift sleepiness. What fails is having no fixed plan and sleeping at a different time every day.
Should I keep my night shift sleep schedule on days off?
As close as you can manage. Fully flipping to a daytime schedule on days off and back again is the most disruptive pattern available, the equivalent of flying across several time zones every week. If staying fully nocturnal is not realistic socially, a compromise anchor works: keep at least a 4-hour core of your sleep window fixed (for example always being asleep 7am–11am), and let the rest flex.
How much sleep do night shift workers need?
The same 7–9 hours as everyone else, but night workers average 1–2 hours less than day workers because daytime sleep is shorter and lighter. That gap accumulates as sleep debt across a run of shifts. Treat the deficit deliberately: track it, and use recovery days and naps to pay it down rather than assuming you have adapted to less.
