How to get through the day after a bad night's sleep
Updated 6 October 2026.
The alarm goes off and you've already been awake long enough to resent it. There's still a day to get through: work, food, people who will ask perfectly reasonable questions.
After a bad night's sleep, don't drive if you're sleepy, cut your day's demands where you can and keep caffeine early. If you choose to nap, keep it brief; tonight, leave room for sleep and aim to keep your usual wake time tomorrow.
What's the first thing to do after a bad night?
Check how sleepy you are before deciding what you can safely do.
If you're struggling to keep your eyes open, don't drive. Arrange another way to travel or delay the journey. That's the advice on the NHS insomnia page.
Sleep loss can affect concentration, reactions and decision-making, as The Sleep Charity explains. Take that into account with machinery or any task where a lapse could hurt someone.
If you're exhausted but don't feel likely to doze off, our tired-but-wired article explains the difference.
How can I make the working day easier?
Reduce avoidable demands where you can, and give important work a second check.
Look at today's list. What needs doing? What could wait until tomorrow? If a consequential decision can reasonably wait, consider moving it. If it can't, write down the details and ask someone to check the parts that matter.
In practice, that might mean postponing an optional meeting, taking a proper lunch break or sending one necessary reply instead of clearing the entire inbox.
Some days offer very little flexibility. You may still have customers, children or a shift to get through. Be specific about any help you ask for: someone checking a calculation, covering a journey or taking one task off your hands is easier to arrange than a vaguely “easier day”.
A short outdoor break can fit here too. Walk to buy lunch or step outside between meetings. It gives you a break from the task in front of you without adding another job to the list.
Should I drink more coffee?
An early coffee can help you feel more alert, but repeated top-ups later in the day may interfere with tonight's sleep.
The Sleep Charity's caffeine guidance explains that caffeine increases alertness and that people differ in how strongly it affects their sleep. Some notice an effect even from midday.
The NHS advises avoiding tea and coffee for at least six hours before bed. For an 11pm bedtime, that means stopping by 5pm, or earlier if you know you're sensitive.
If you normally drink coffee, keep an eye on how many cups this tired day is becoming. Feeling more alert doesn't replace the sleep you missed.
Would a nap help?
A short nap may improve alertness, but it depends on whether this is an occasional bad night or an ongoing sleep problem.
The Sleep Charity's FAQs recommend keeping planned naps to about 20 minutes and advise avoiding them if you struggle with insomnia or regularly sleep poorly. The NHS insomnia guidance also advises against daytime naps.
After an occasional short night, a brief nap may be useful if your day allows it. If you choose one, set an alarm and leave it early enough that it doesn't run into your evening.
If difficult nights are becoming a pattern, follow the advice for insomnia or the plan you've agreed with your clinician.
Should I go to bed much earlier tonight?
Keep your usual wake time tomorrow, and go to bed around your normal time or slightly earlier if you're sleepy.
Bringing the evening's jobs forward may be more useful than declaring an ambitious new bedtime. Have dinner, sort out what you need for tomorrow and leave optional jobs alone. That way, when you do feel sleepy, you're ready.
Skip using alcohol to help you drop off. The same NHS guidance recommends avoiding it for at least six hours before bed.

What if this keeps happening?
Speak to your GP if sleep problems make daily life hard to cope with, or you've felt tired for weeks without knowing why; the NHS pages on insomnia and tiredness and fatigue explain when to seek help.
Mention loud snoring or gasping, snorting or choking during sleep if someone has noticed it. The NHS lists these alongside daytime tiredness as possible signs of sleep apnoea.
