How to fall asleep fast, without trying harder

What makes sleep come quickly

Two things decide how fast you drift off. The first is how much sleep pressure you have built up, which depends on how long you have been awake and how well you slept the night before. The second is how activated you are. A racing mind, a tense body or a bright room all keep the brakes on, however worn out you feel.

Most good advice about falling asleep fast works on one of those two. A consistent wake time, daylight in the morning and no long late naps raise sleep pressure by bedtime. A dim, quiet last hour and a simple routine in bed lower activation. Doing a little of both beats hunting for one perfect hack.

It also helps to know what normal looks like. Healthy sleepers rarely drop off the instant their head touches the pillow, and falling asleep within moments every night can be a sign of being short on sleep rather than a talent. The realistic goal is to stop lying awake for long stretches, not to switch off like a light.

Set it up before bed

• Keep your wake time steady. Getting up at the same time every day, weekends included, is the most reliable way to feel sleepy at a similar time each night.
• Warm up, then cool down. A 2019 review in Sleep Medicine Reviews pooled studies of warm showers and baths and found that bathing in warm water one to two hours before bed was linked with falling asleep sooner. Warm water draws heat to the skin, and the cooling that follows supports sleepiness. A cool bedroom finishes the job; see too hot to sleep.
• Write tomorrow down. In a 2018 sleep lab study, people who spent five minutes writing a specific list of upcoming tasks at bedtime fell asleep faster than people who wrote about tasks they had already finished.
• Dim the last hour. Lower the lights, put work away and choose something calm and familiar to do.
• Watch the afternoon coffee. Caffeine lingers for hours; our guide on how long caffeine keeps you awake explains why.

In bed, a short routine for tonight

1. Slow the exhale. Spend two or three minutes on a breathing pattern with a long out-breath, such as the physiological sigh or 4-7-8 breathing.
2. Loosen what is tight. Let your jaw, shoulders and hands go heavy, or run a quick round of progressive muscle relaxation.
3. Hand your mind one neutral thing. A slow, boring scene or a stream of unrelated images, as in the cognitive shuffle, keeps the planning part of your brain from taking over.
4. Stop checking. Turn the clock away. Every look starts a countdown that wakes you further.

The well-known military sleep method is essentially this sequence in compact form. The exact steps matter less than repeating the same ones every night until they run on autopilot.

What slows sleep down

Some habits that feel helpful push sleep later. Trying hard is the big one, because effort and self-monitoring are forms of alertness. If that sounds familiar, paradoxical intention, gently trying to stay awake instead, can take the pressure off.

Others include going to bed long before you feel sleepy, scrolling in bed, a nightcap that breaks up the second half of the night, and a long nap late in the afternoon. If you have been lying awake for what feels like a long time and frustration is building, get up for a short while in dim light and return when your eyes are heavy. Our guide on what to do when you can't sleep walks through it.

If it regularly takes you a long time to fall asleep despite good habits, or poor nights are affecting your days, talk to a clinician. Structured, non-drug programs for sleeplessness are widely available.
