What to Do When You Can’t Fall Asleep
The honest answer first: one bad night is not a problem. It’s unpleasant, and tomorrow will be a slog, but a single stretch of lying awake doesn’t mean anything is wrong with you. What you do in the next hour matters less for tonight than it does for the nights after it — because the thing that turns a few sleepless nights into a habit is the association your brain builds between your bed and being awake.
So here’s what actually helps at 1am.
Stop trying to fall asleep. Sleep isn’t a task you can complete by effort, and the harder you push, the more alert you get. Swap the goal. Instead of “I need to be asleep,” aim for “I need to be calm and horizontal.” Slow breathing, a body scan, letting your jaw and shoulders go — these are worth doing not because they knock you out but because they stop the escalation.
Don’t look at the clock. Once you start doing arithmetic on how many hours are left, you’ve added a deadline to a process that can’t be rushed. Turn the phone face down, or put it across the room.
Get the light down and stay off screens. If you do get up, keep the room dim — enough to read by, not enough to feel like morning.
And if it’s clearly not happening, leave the bed. That’s the part most people skip, and it’s the part that does the most work.
How Long to Wait Before Getting Out of Bed
The common benchmark is twenty minutes. Mayo Clinic’s sleep tips say that if you don’t fall asleep within about 20 minutes of going to bed, leave your bedroom and do something relaxing, then go back to bed when you’re tired. Their guidance on insomnia gives the same advice for a middle-of-the-night wake-up: if you can’t get back to sleep within about 20 minutes, get out of bed and read or do something quiet elsewhere until you feel sleepy.
Two things about that number that nobody tells you.
First, it’s not meant to be timed. Twenty minutes is roughly how long it takes before lying there stops being restful and starts being frustrating, and you can feel that shift without a clock. If you’re calm and drifting at minute thirty, stay put. If you’re tense and rehearsing an argument at minute eight, get up. The point isn’t the interval, it’s the state you’re in.
Second, getting up feels wrong. It feels like giving up your chance at sleep, and at 2am your brain will argue hard that staying still is better than admitting defeat. That’s the hard part of this advice and it’s why most people ignore it. What you’re actually doing is protecting the signal — bed means sleep — so that on an ordinary night, lying down is enough to make you drowsy.
Go somewhere else. Do something dull and undemanding in low light. Come back when your eyes are heavy, not when you think you should be asleep by now.
For reference, the Sleep Foundation puts a typical, healthy sleep onset at under 20 minutes. Falling asleep the instant your head hits the pillow, every night, isn’t the gold standard it sounds like — it can be a sign you’re running short on sleep overall.
Common Reasons You Can’t Fall Asleep
Most sleep-onset trouble comes down to one of three things, and telling them apart changes what you do.
Your body isn’t ready yet. You went to bed at the time you think you should be asleep, not the time your body is sleepy. This is the most common and the most fixable. If you’ve shifted your bedtime earlier by an hour, or you’re on holiday, or you slept in on the weekend, your internal clock hasn’t moved with you. Nothing is wrong; the timing is off. Our sleep tools can help you work out when your own sleep window actually falls rather than guessing at it.
Something is still in your system. Caffeine lingers longer than most people assume — the Sleep Foundation suggests cutting it off at least six to eight hours before bed. Nicotine is stimulating too, and Mayo’s sleep tips above note that the effects of both take hours to wear off. Alcohol is the sneaky one: it can make you drowsy at first while interfering with sleep quality later in the night. If your problem is falling asleep rather than staying asleep, look at the afternoon coffee first.
Your mind won’t stand down. A racing head at bedtime is often the only quiet hour you’ve had all day, so everything unprocessed arrives at once. This one responds better to moving the thinking earlier — a written list at 8pm, ten minutes of deliberate worry time — than to trying to suppress it at midnight.
Then there are the causes a checklist won’t fix. Pain, breathing problems, restless legs, an unsettled mood: Mayo’s insomnia guidance above points out that insomnia is sometimes caused by conditions like sleep apnoea, restless legs syndrome, long-term pain or depression, and that treating the underlying condition may be what’s needed for the sleep to improve. If you’ve tidied up your habits and nothing shifted, that’s the direction to look — and it’s worth reading why you can’t sleep even though you’re tired, because exhaustion plus wakefulness is a specific pattern with its own set of explanations.
When Occasional Sleeplessness Becomes Insomnia
There’s no bright line you cross, but frequency and duration are what clinicians pay attention to. The Sleep Foundation’s guidance on what to do when you can’t sleep, linked above, names trouble sleeping at least three nights a week for over a month as a reason to talk to a healthcare provider — along with sleep problems that are affecting your mood, energy, focus or day-to-day functioning, and leaning on over-the-counter sleep aids or alcohol to get to sleep.
Three nights a week, for weeks. That’s the shape to watch for. A rough fortnight after a bereavement or before a deadline is your body responding to your life. A pattern that’s been running since spring, that you now plan around, that has changed how you feel at 4pm — that’s different, and it usually doesn’t resolve on its own.
Worth noting: the pattern can drift. People often start with occasional bad nights, then begin dreading bedtime, then start going to bed earlier to “catch up,” which means more time awake in bed, which strengthens the wrong association. If that arc sounds like the last few months of your life, why you can’t sleep at night anymore walks through what tends to be behind a change in sleep that used to be fine.
Should You See a Doctor About Sleep Onset Problems
Take it to a clinician if the pattern has lasted, if it’s costing you during the day, or if any of these are in the mix:
- You’re sleepy in the daytime despite spending eight or more hours in bed — the Sleep Foundation’s page on how long it should take to fall asleep, above, flags that as a reason to speak to a provider.
- Your sleep difficulty is significantly interfering with daily activities.
- Someone has told you that you snore heavily, gasp or stop breathing in your sleep.
- Your legs feel restless or crawling in the evening and moving them is the only relief.
- Low mood, anxiety or pain is part of the picture.
- You’ve changed your habits genuinely, for a few weeks, and nothing moved.
A doctor can work out whether something else — another condition, or a medication you’re taking — is driving it, and there are structured, non-drug approaches to persistent insomnia that a clinician can discuss with you. None of that requires you to have exhausted every tip on the internet first.
If you’re not sure whether what you’re experiencing is worth an appointment, our sleep disorder quiz walks you through the patterns clinicians ask about and tells you which ones are worth raising. It isn’t a diagnosis, and it can’t be one — but it’ll give you a clearer account of your own nights than “I don’t sleep well,” which is a much better place to start a ten-minute consultation from.
And tonight, if you’re reading this in the dark: put the phone down, get up if you’re wound tight, keep the lights low, and let tomorrow be a slightly rough day. It usually is just the one.
