How to fall asleep fast when you're not tired
You can't make yourself sleepy on command, but you can stop fighting it and help sleepiness arrive sooner. Dim the lights, get off screens, do something calm and a little boring out of bed, take a warm shower, write down what's on your mind, and go to bed the moment your eyes get heavy. Lying in bed wide awake trying to sleep is the one move that reliably makes it slower.
If you're not tired because you napped, slept in, or your body clock runs late, the real fix is tomorrow morning: get up at your normal time and keep the day awake, so tomorrow night you're sleepy on time. Below: why you're not sleepy, what to do tonight by situation, the early-start night, and how to stop it happening again.
Why you're not tired at bedtime
Sleepiness comes from two things. Sleep pressure builds every hour you're awake and drains while you sleep (a nap drains it early). Your body clock decides which hours feel like night. Most people also hit a "second wind" an hour or two before their natural sleep time, when the clock pushes hardest to keep you awake. Not feeling tired at 10 p.m. usually means one of these:
| Today you... | What's going on | What helps most |
|---|---|---|
| Napped, or dozed on the couch after dinner | Sleep pressure partly spent | Stay up until sleepy; no lie-in tomorrow |
| Slept in until 10 or 11 | Pressure started late, and the clock moved later | Usual wake-up time tomorrow, morning light |
| Want to sleep 2 hours early (a flight, a new job) | You're in your second wind | Wind down in dim light; expect a short night |
| Had coffee, tea, cola or energy drinks after lunch | Caffeine blocks the sleep-pressure signal | Wait it out calmly; noon cut-off from tomorrow |
| Spent the day sitting, indoors, in low light | Little pressure, weak clock signal | Daylight and movement tomorrow |
| Came off a night shift or a long flight | Clock set to another time zone | Light and meals at the new times (see below) |
| Feel buzzy, alert, on edge | Stress hormones up: tired but wired | Write it down, slow breathing, a dull task |
If you're exhausted but still can't drop off, that's a different problem: read can't fall asleep even when you're tired. If you lie awake most nights whatever you did that day, start with what to do when you can't fall asleep.
Should you go to bed if you're not tired?
Usually not. Sleep researchers draw a clear line between being in bed and being sleepy. Getting into bed wide awake, then lying there for an hour, does two things: it adds frustration, and over weeks it teaches your brain that bed is a place to be awake. That habit is at the centre of long-term insomnia, which is why the stimulus control rules in CBT for insomnia say "go to bed only when sleepy".
The exception is a one-off night when you must be up very early. Even then, it's better to wind down until you feel any drowsiness, then go to bed, than to lie in the dark from 8 p.m.
What to do tonight, step by step
- Drop the lights now. Turn off ceiling lights and use one lamp, low and warm. Bright light in the late evening holds back melatonin, the hormone that signals night. Dim light lets it rise.
- Put the phone down, or at least make it boring. The bigger problem with phones at night is the content: messages, news and feeds keep the brain engaged. If you must use a screen, pick something you've seen before, turn the brightness right down and stop scrolling. Our guide to screens before bed covers what the studies found.
- Take a warm shower or bath. A review of 17 studies found warm water (about 104 to 108°F) 1 to 2 hours before bed helped people fall asleep faster (Haghayegh and colleagues, 2019). If bed is sooner than that, still do it: 10 minutes is enough.
- Empty your head onto paper. Five minutes writing tomorrow's to-do list helped people in a Baylor study fall asleep faster than writing about what they'd done (Scullin and colleagues, 2018).
- Do something calm, dull and away from the bed. A paper book you've read before, folding washing, a jigsaw, gentle stretching, an audiobook you know. Avoid anything you'll want to finish, and anything that needs bright light.
- Watch for the signs, then go. Heavy eyes, yawning, reading the same line twice, your head dropping. Go to bed at the first sign; the window can pass.
- In bed, give your mind a job. Slow breathing (in for about 4 seconds, out for about 6), a body scan, or picturing a walk you know in detail.
- Not asleep after about 20 minutes? Get up and go back to step 5. Don't check the clock to measure it; a rough feel is fine.

When you have to be up early and you're wide awake
A 5 a.m. flight, a first day, an exam. This is the most common reason people search this, and the most stressful. The honest answer: your body clock can't be moved 3 hours in one night. What you can do is protect the sleep you'll get and the day after.
- Take the pressure off. One short night is unpleasant but not dangerous for a healthy adult, and people perform better than they fear after one. Worrying about the alarm is what keeps most people awake.
- Go to bed about 30 to 60 minutes earlier than usual, not 3 hours. That's roughly as early as your clock will let you sleep.
- Lie quietly if you can't sleep and don't feel upset. For this one night, calm rest in the dark is a fair second best. If you're getting frustrated, get up for 15 minutes instead.
- Set two alarms so you stop checking the time.
- Plan the morning: bright light as soon as you wake, coffee then (not later than noon), and no driving if you're drowsy. A short nap (20 minutes, before 2 p.m.) is fine the day after a short night.
- For a known early start in a week or two, move your wake-up time 15 to 30 minutes earlier every 2 to 3 days, with morning light, so your clock is there in time. Our guide to fixing your sleep schedule has a plan with clock times.
After a nap or a lie-in
A long nap late in the day, or sleeping until noon, means you start the night with less sleep pressure. You will probably fall asleep later tonight, and that's fine. The trap is lying in again tomorrow to make up for it, because that keeps the cycle going. Instead:
- Go to bed when sleepy, even if that's 1 a.m.
- Get up at your usual time tomorrow. Set an alarm.
- Get outside within an hour of waking.
- No nap tomorrow, or 20 minutes at most before 2 p.m.
By the second night most people are sleepy on time again.
After a night shift, jet lag, or the clocks changing
Here your clock is set to the wrong hours. Sleepiness will come at its old time until light and routine move it.
- Flying east or after the clocks spring forward: bright light in the morning at your new location, dim light in the evening, and get up at your new usual time.
- Flying west or after the clocks fall back: light in the late afternoon and evening, and stay up to your local bedtime.
- Back on days after nights: a short sleep after your last shift (around 3 to 4 hours), then stay up until a normal bedtime, with daylight in the afternoon.
- Melatonin has evidence for jet lag: a Cochrane review found 0.5 mg and 5 mg worked similarly, taken near the target bedtime at the destination (Herxheimer and Petrie, 2002). Ask your doctor or pharmacist if you take other medicines. See melatonin stopped working? for timing.
Mistakes that keep you awake longer
- Going to bed hours early "to bank sleep". You can't sleep before your clock allows, and the wait in bed builds frustration.
- Checking the clock. Counting the hours left raises your heart rate and alertness. Turn the clock to the wall.
- A nightcap. Alcohol can help you drop off, then breaks up sleep in the second half of the night.
- Hard exercise right before bed. Moderate exercise in the day helps sleep; a hard session in the last hour can leave some people too alert. Gentle stretching is fine.
- Over-the-counter sleep aids. Most contain sedating antihistamines (diphenhydramine or doxylamine). They can leave you groggy the next day, and the American Academy of Sleep Medicine's 2017 guideline suggests not using diphenhydramine for chronic insomnia. Older adults are advised to avoid them because of falls and confusion. Talk to a pharmacist first.
- Sleeping in tomorrow. It feels fair after a bad night, and it sets up the next one.
How to be sleepy at bedtime from now on
If "not tired at bedtime" happens most nights, the fix is in your day, not your night.
| Habit | Do this | Why |
|---|---|---|
| Wake-up time | Same time all 7 days, within 30 minutes | Sets the clock and starts the pressure timer |
| Morning light | 20 to 30 minutes outside within an hour of waking | Pulls the clock earlier |
| Naps | None, or 20 minutes before 2 p.m. | Keeps pressure for the night |
| Caffeine | Last cup by noon | Half-life about 5 hours |
| Movement | Some activity most days, earlier rather than late | Builds pressure, deepens sleep |
| Evening light | Dim the main lights 2 hours before bed | Lets melatonin rise on time |
| Time in bed | Not much more than the hours you actually sleep | Long hours in bed make sleep shallow and slow to start |
If you're not sure how many hours you really need, our guide to how many hours of sleep you need has a 2-week test. The free 2-minute sleep quiz also works out a starting bedtime from your wake-up time and how long you actually sleep.
When to see a doctor
- You're never sleepy before 2 or 3 a.m., even after weeks of fixed wake-up times, and it's hurting work or family life (a late body clock disorder can be measured and treated).
- You feel unusually full of energy, need much less sleep than usual and feel racing or reckless (see a doctor soon; this can be a sign of a mood condition).
- You lie awake more than 30 minutes, 3 nights a week, for 3 months.
- A medicine, a thyroid problem, pain or restless legs might be involved.
Frequently asked questions
Is it bad to stay up until I'm tired?
No, as long as you still get up at your usual time. Staying up until sleepy and keeping the wake-up time fixed is part of standard insomnia treatment.
How can I make myself tired quickly?
You can't add much sleep pressure in an hour. What you can do is remove what's blocking it: bright light, screens with engaging content, worry and frustration. Dim light, a warm shower and a dull task let the sleepiness you have show itself.
Is lying in bed awake as good as sleeping?
No. Calm rest is better than stress, but it isn't sleep. For one night it's a fair fallback; as a habit it makes sleep worse.
Why do I get a second wind at night?
Your body clock pushes alertness up in the hours before your natural sleep time, to keep you awake through the evening. If you try to sleep in that window, you'll feel wide awake.
Will melatonin make me tired?
Not much. It's a timing signal more than a sedative: in trials it shortened time to fall asleep by about 7 minutes on average. It helps more for jet lag and late body clocks.
Should I pull an all-nighter to reset?
It rarely works, because your clock doesn't move. Most people slide back within days. Moving the wake-up time in steps works better.
Tonight
Dim the lights, write tomorrow's list, and do something calm out of bed until your eyes get heavy. Set your usual alarm for the morning and keep it, however the night goes. If you'd like your own numbers, the free sleep quiz takes 2 minutes. More in our sleep guides.
