How Long Should It Take to Fall Asleep? What Is Normal and What Helps

Lying awake for a little while before sleep is completely normal. Sleep is not a switch. It is a slope, and most people take a few minutes to slide down it. The trouble starts when we treat those minutes as a failure and begin to try harder.

This article covers what sleep experts consider a healthy time to fall asleep, why effort keeps you awake, a gentle breathing routine for the waiting time, and the point where it is worth talking to a clinician.

How long should it take to fall asleep?

For most adults, falling asleep within about 30 minutes is treated as a sign of good sleep quality. That comes from a National Sleep Foundation panel of experts that reviewed 277 studies and agreed that the time it takes to fall asleep, called sleep latency, is a fair marker of sleep quality across the life span (Ohayon et al., 2017).

So if you take 10, 15 or 20 minutes, nothing is wrong. Some nights will be longer, especially after a stressful day, a late coffee or a late nap.

Falling asleep within a minute or two every single night is not necessarily a prize. It can mean you are carrying a sleep debt. If that is you, and you are also sleepy in the day, it is worth looking at how much sleep you are getting.

Why trying harder keeps you awake

Sleep comes when the body's alert system quiets down. Effort does the opposite. Checking the time, calculating how many hours are left, and telling yourself to sleep all keep the alert system busy.

This is not just theory. In an experiment with 30 good sleepers and 30 poor sleepers, people told to watch a clock while trying to sleep reported more worry and took longer to fall asleep than people who did not watch it. That held true for good sleepers too (Tang et al., 2007).

The answer is to give your attention something calm and neutral to do, so it stops policing your sleep. A slow breath is ideal for that.

A breathing routine for the time before sleep

1. Turn the clock away. Before you start, make sure you cannot see the time.
2. Lie in your usual sleep position. No need to lie on your back if you sleep on your side.
3. Breathe in through your nose for 4 seconds. Soft and normal sized.
4. Breathe out for 6 seconds. Slow, easy, like a long sigh without the sound.
5. Keep going for about 10 minutes. Roughly 60 breaths.
6. Let the counts drift. When you lose track, that is often drowsiness arriving. Let it.
7. Beginner fallback. If counting keeps you alert, skip numbers and simply make each exhale a little slower than the inhale.

Habits that shorten the wait

Breathing helps with the minutes in bed. These habits help with what happens before you get there.

• Go to bed when sleepy, not just tired. Sleepy means heavy eyelids and nodding off. Tired can mean worn out but wired. Only the first predicts quick sleep.
• Keep a steady wake-up time. Getting up at the same time every day, weekends included, makes sleepiness arrive at a more predictable hour.
• Give caffeine a long runway. Many people need to stop several hours before bed.
• Dim the last hour. Lower lights and fewer screens make it easier for the body clock to signal night.
• Park tomorrow on paper. A short written list of what you need to do the next day can stop the mind from rehearsing it in bed.

None of these is dramatic. Together they move the slope toward sleep a little earlier and make it a little steeper.

Why some nights take longer than others

Even good sleepers have slow nights. A big meal, alcohol, an argument, exercise late in the evening, a warm room, or a change in time zone can all add minutes. So can excitement about something good. Look at the pattern over a couple of weeks rather than a single night. A rough guide: if most nights are within half an hour and the occasional night is longer, your sleep is working as it should.

What the research shows

• Expert panel, 277 studies reviewed: sleep latency is an appropriate indicator of good sleep quality, with up to about 30 minutes counted as good for most adults (Ohayon et al., 2017).
• 14 people with insomnia, 20 minutes of slow paced breathing before bed: shorter time to fall asleep and fewer awakenings on lab sleep recordings (Tsai et al., 2015).
• 60 good and poor sleepers, then 38 people with insomnia: watching a clock while trying to sleep raised worry and lengthened time to fall asleep (Tang et al., 2007).
• Insomnia guideline: for chronic trouble, multicomponent cognitive behavioral therapy for insomnia is strongly recommended (Edinger et al., 2021).

The takeaway: a little time awake is normal, effort makes it longer, and slow breathing is a gentle way to fill the wait. The breathing evidence is small, so judge it by how your nights feel over a few weeks.

Common mistakes

• Going to bed before you are sleepy. An early bedtime "to get a head start" often means more time lying awake.
• Calculating hours left. Every calculation wakes you up a little more.
• Treating 20 minutes as insomnia. It is within the normal range.
• Long naps late in the day. They reduce the sleep pressure you need at bedtime.

Who should be careful

• People who take more than about 30 minutes to fall asleep most nights for months: this may be insomnia, and cognitive behavioral therapy for insomnia is the recommended treatment. See a clinician.
• People who fall asleep instantly and are very sleepy in the day: you may be short on sleep, or have a sleep disorder. Mention it to a doctor.
• People who snore loudly or wake gasping: these can be signs of sleep apnea, which breathing exercises do not treat.
• Anyone who feels dizzy during breathing practice: stop, breathe normally, and use smaller breaths next time.
