If you go to bed at 5:00 AM (05:00), wake up at 2:15 PM (14:15) for 9 hours of sleep, or 12:45 PM (12:45) for 7.5 hours. 11:15 AM (11:15) gives 6 hours. All times allow 15 minutes to fall asleep.

Your adjusted wake-up times

    Counting forward from 5:00 AM

    If you get into bed at 5:00 AM and fall asleep about 15 minutes later, your first sleep cycle starts at 5:15 AM. Adding cycles of about 90 minutes gives:

    • 11:15 AM (11:15) after four cycles, or 6 hours asleep;
    • 12:45 PM (12:45) after five cycles, or 7.5 hours;
    • 2:15 PM (14:15) after six cycles, or 9 hours.

    Which wake-up time fits a 5 AM bedtime?

    12:45 PM gives 7.5 hours, above the 7-hour minimum recommended for adults. For most night-shift workers it leaves time for the afternoon before the next shift.

    2:15 PM gives 9 hours, useful after a run of short sleeps or before a demanding shift.

    11:15 AM gives 6 hours. Daytime sleep is often lighter and more broken than night sleep, so 6 hours in the day can feel like less.

    If you take more or less than 15 minutes to fall asleep

    The times above allow 15 minutes to fall asleep. After a night shift, many people take longer to drop off. Use the row that matches you; the highlighted row matches the answer at the top.

    Making daytime sleep work

    Sleeping after sunrise is harder than sleeping at night, because daylight and noise tell your body clock it is time to be awake. A few changes make a real difference:

    • Use blackout curtains or an eye mask, and earplugs or a fan for steady background noise.
    • Put your phone on silent and let others in your home know when you are sleeping.
    • Keep the bedroom cool, as it usually warms up during the day.
    • On the way home after a night shift, some people find sunglasses help them feel less wide awake.
    • Avoid caffeine in the last few hours before your planned bedtime.

    A routine for regular night shifts

    If you work nights regularly, try to sleep at the same times after each shift and keep a similar pattern on days off where you can. Some people split their sleep, with a main sleep after the shift and a short nap before the next one. If you often feel exhausted or struggle to sleep despite good habits, talk to a doctor.

    Frequently asked questions

    Is going to bed at 5 AM bad for you?

    Not in itself, if you still get enough sleep and keep a regular pattern. Allowing 15 minutes to fall asleep, a 5:00 AM bedtime gives 7.5 hours with a 12:45 PM (12:45) alarm.

    How much sleep do I get from 5 AM to noon?

    About 6 hours 45 minutes, if you fall asleep by 5:15 AM. That is a little below the adult minimum of 7 hours, and the alarm falls partway through a cycle.

    Why is it so hard to sleep after a night shift?

    Your body clock is set to be awake in daylight, so daytime sleep tends to be lighter and shorter. A dark, quiet, cool bedroom and a regular schedule make it easier.

    When to seek help

    Talk to a doctor if you:

    • regularly take longer than 30 minutes to fall asleep, or wake in the night and can’t get back to sleep;
    • snore loudly, or someone notices you gasp or stop breathing while asleep;
    • feel very sleepy during the day, especially while driving or working, despite enough time in bed.
