Quick answer

Stayed late at the office and cannot switch off? Learn how to wind down, when to sleep, and how to plan the next day so one late night does not turn into a habit.

Plan your night

Enter the time it ended and your alarm. The planner adds the wait you choose before lying down and shows the alarm times that end a sleep cycle.

Wind down in 30 to 60 minutes

You cannot go from an email thread to deep sleep in five minutes. A short buffer makes a big difference.

  1. Write down tomorrow's three top tasks and any worries on paper. Getting them out of your head helps you stop rehearsing them.
  2. Eat something light if you have not had dinner, and finish at least 2 hours before lights out if you can. See how long to wait after eating.
  3. Put the phone on do not disturb. Close work email and chat.
  4. Take a warm shower and dim the lights.
  5. Do something calm for 15 minutes, such as reading or quiet music.
  6. Go to bed when you feel sleepy, and keep the room cool and dark.

When to wake if you get home late

If you get to bed at 1:00 AM, you can compare wake times with the table.

Choose the wake time that still gives you at least 5 cycles when possible. If the night is short, keep the wake time near normal and plan an earlier bedtime for the next night. The sleep hours calculator shows the total.

The next day

  • Wake within an hour of your usual time if you can.
  • Get daylight, water and a proper breakfast.
  • Do your hardest thinking in your best hours, see the chronotype quiz.
  • Take a 10 to 20 minute nap if you need it, before about 3 PM.
  • Stop caffeine 8 to 10 hours before bed.
  • Finish work on time tonight and protect your sleep.

Drowsy driving is dangerous. If you feel very sleepy on the way home, pull over somewhere safe for a short nap.

When late nights become a habit

One late night costs little. A run of them builds sleep debt and pushes your body clock later. If it happens more than a couple of times a week, talk to your manager about workload and deadlines, set a hard stop time, and check your total using the sleep debt calculator and the bedtime procrastination calculator.

Shift patterns that change every week need extra care, see the shift work sleep calculator and starting a new job.

When to get advice

If you feel constantly exhausted, have trouble sleeping for months, or notice low mood or anxiety, speak to a doctor. A calculator cannot replace care.

Frequently asked questions

How do I switch off after working late?

Write down tomorrow's tasks, turn off notifications, take a warm shower and do a calm activity for 15 minutes.

How much sleep should I get after a late finish?

Aim for at least 5 cycles, about 7.5 hours, if you can. If not, keep the wake time near normal and sleep earlier the next night.

Is it OK to sleep in after a late night?

A little extra is fine. A very late wake time shifts your body clock.

Should I drink coffee to get through the next day?

Use it in the morning only, and stop 8 to 10 hours before bedtime.

How do I stop late working becoming a habit?

Set a hard stop time, protect a bedtime routine and review workload with your manager.

How many hours do teenagers and children need?

CDC guidance lists 8 to 10 hours for ages 13 to 18, 9 to 12 hours for ages 6 to 12, 10 to 13 hours for ages 3 to 5 including naps, and 11 to 14 hours for ages 1 to 2 including naps.

How do I move my bedtime earlier?

Shift it by 15 to 30 minutes every two or three days while keeping the wake time fixed, get bright light after waking and dim lights for an hour before bed.

How many sleep cycles do I need per night?

Most adults do well with 5 cycles (about 7.5 hours) and some need 6 (about 9 hours). Four cycles, about 6 hours, is short for most people and is better used as an occasional fallback than a habit.
