How Long Does It Take to Fall Asleep? What's Normal and What's Not

How long it takes to fall asleep is one of those numbers people rarely think about until it starts to stretch out. For most healthy adults it's somewhere around 15 to 20 minutes, but both "much longer" and "almost instantly" can tell you something. This guide covers what a normal time to fall asleep looks like, what it means if you drop off in seconds, why it can take longer, what to do when you can't get to sleep, and when it's worth seeing your GP.

The short answer: most healthy people fall asleep within about 15 to 20 minutes of lying down. Taking a little longer on some nights is normal. Regularly falling asleep the moment your head hits the pillow often means you're short on sleep, not that you're a great sleeper. If it regularly takes you more than half an hour, and that's happening at least three nights a week for three months and affecting your days, that fits the pattern of insomnia and is worth raising with your GP.

What's a normal time to fall asleep?

The time it takes to fall asleep after you turn the light off is called sleep onset latency. The Sleep Foundation says "most healthy people fall asleep within 15 to 20 minutes of lying down" (source).

That's a rough guide, not a target. A few points help keep it in perspective:

• It varies night to night. Stress, a late coffee, a hot night or a big day all shift it.
• Clock-watching distorts it. Many people find that time spent lying awake feels longer than it is, especially when they keep checking the time.
• You can't force it. The Sleep Health Foundation puts it simply: "You cannot make yourself fall asleep – just like you can't digest your food faster" (source). Trying harder usually makes it take longer.

What your time to fall asleep might mean

How long it usually takes	What it may suggest	What to do
Under 5 minutes, most nights	Often a sign of sleep debt	Look at how much sleep you're actually getting
About 10 to 20 minutes	Typical for a healthy adult	Nothing; carry on
20 to 30 minutes now and then	Normal variation	Check caffeine, screens and stress on those nights
Over 30 minutes, most nights	Possible insomnia, body clock mismatch or another factor	Try the steps below; see your GP if it persists

Falling asleep instantly isn't always good

It's tempting to think dropping off in seconds is a sign of healthy sleep. Often it isn't. The Sleep Foundation explains that a sleep-deprived person falls asleep faster than someone who is well rested. If you're out like a light every night, ask whether you're getting the 7 to 9 hours most adults need. See how much sleep do I need.

Falling asleep very quickly combined with strong daytime sleepiness, nodding off in meetings or in the car, is a reason to see your GP. The Sleep Foundation notes it can sometimes be linked to medical conditions, not just a short night.

Why it can take longer

The Sleep Foundation lists several common reasons it takes a long time to drop off:

• Insomnia, where trouble getting to sleep or staying asleep becomes a pattern.
• A body clock out of step with your bedtime, as with jet lag, shift work or a late chronotype. See night owl or early bird.
• Worry, low mood or pain. See racing thoughts at night.
• Some medicines, including stimulants and some antidepressants. Don't stop a medicine without talking to your doctor.
• Caffeine, nicotine or alcohol too close to bed. See caffeine and sleep.
• The room itself: noise, light or temperature.
• Going to bed before you're sleepy, which is common after a long nap or a sleep-in.

What to do if you can't fall asleep

1. Get up if you're not asleep in 15 to 20 minutes. This is part of stimulus control, a technique in cognitive behavioural therapy for insomnia (CBT-I). The Sleep Health Foundation describes it as "getting out of bed if you can't sleep within 15-20 minutes, and only sleeping at night in bed" (source). Don't time it to the minute; if you feel like you've been awake a while, get up.
2. Do something quiet in dim light. Better Health Channel suggests getting up and doing something else for half an hour or so, such as reading a book, then trying again.
3. Go back to bed when you feel sleepy, not just tired.
4. Turn the clock around. Checking the time adds pressure.
5. Keep the same wake time the next morning, even after a bad night. It builds sleep pressure for the next night. See fixed wake-up time.
6. Build a wind-down routine. See how to fall asleep faster for the full set of techniques.

When it might be insomnia

Healthdirect describes chronic insomnia as having trouble falling asleep or staying asleep at least three nights per week for at least three months, in a way that affects how you function during the day. It recommends CBT as the usual first treatment if sleep strategies and relaxation haven't helped (source). The Sleep Health Foundation notes that a GP can set up a mental health treatment plan for Medicare-supported sessions with a psychologist trained in CBT-I. See insomnia: what helps.

When to see your GP

See your GP if it regularly takes you more than half an hour to fall asleep and it's affecting your days, if you're falling asleep almost instantly and still sleepy during the day, or if you snore heavily or wake gasping. A sleep diary kept for two weeks is useful to take along. This guide is general information, not medical advice.

Quick answers

Is it normal to take an hour to fall asleep? Now and then, yes. If it happens most nights for months and affects your days, talk to your GP.

Is falling asleep in 5 minutes bad? Not on its own, but if it happens every night it often means you're not getting enough sleep.

Should I stay in bed if I can't sleep? Generally no. If you've been awake for around 15 to 20 minutes, get up, do something quiet in dim light and come back when sleepy.

Does lying still with your eyes closed count as rest? It can feel restful, but it isn't sleep. The Sleep Health Foundation lists staying in bed when you can't sleep as one of the habits that keeps insomnia going.
