Most "fall asleep faster" lists give you fifteen tips of equal weight, which is unhelpful, because they're not of equal weight. Two of them do most of the work and the rest are marginal.

Here they are ranked by how much difference they're likely to make.

1. Get up at the same time every day

This is the highest-leverage change on the list, and it's the one almost nobody wants to hear, because it means giving up the lie-in.

Your ability to fall asleep quickly depends on two things: sleep pressure, which builds the longer you've been awake, and your circadian timing, which is anchored primarily by when you get light in the morning. A consistent wake time stabilises both. An inconsistent one — up at 6:30 on weekdays, 10:00 at weekends — means that on Sunday night you've been awake for less time and your body clock has drifted later. You're then in bed with insufficient sleep pressure, which is a fairly good description of what Sunday night insomnia is.

Fixing bedtime doesn't do the same work. You can't force sleepiness at a chosen hour. You can control what time you get up, and the bedtime follows.

2. Make the room properly dark

Light is the strongest input to your circadian system. Even relatively low-level light at night suppresses melatonin, and light during the sleep period is associated with disrupted sleep.

"Properly dark" is a higher bar than most people think. Standing in your bedroom with the lights off and being able to make out the wardrobe means it isn't dark. Blackout curtains help but almost always leak at the edges. Standby LEDs on a TV or router are brighter than they seem at 3am.

This is where a mask does the job that curtains can't: it blocks light at the eye, so it doesn't matter what your curtains, your partner, or the street outside are doing. We've written the full version of this argument in why sleeping in total darkness changes everything.

Being upfront: we sell sleep masks, so of course we rank this highly. We think it stands up regardless, but you should weigh it accordingly.

3. Get the room cooler than feels intuitive

Your core body temperature has to drop for sleep to begin. A warm room works against that, which is why summer nights are harder and why a hot bath an hour before bed actually helps — the subsequent drop as you cool down is the useful part.

Most sleep guidance lands somewhere in the region of 16–19°C, which is cooler than most people keep a living room. That's a widely repeated range rather than a precise clinical threshold, so treat it as a starting point and adjust to what works for you.

If you're waking up hot, the material of everything touching your skin matters. Polyester traps heat. This is a specific problem with cheap sleep masks — a foam or polyester mask sits directly on your face and insulates it. Silk doesn't, which is one of the more practical reasons to care about what a mask is made from.

4. Stop lying in bed awake

If you've been in bed unable to sleep for what feels like twenty or thirty minutes, get up. Go to another room, keep the lights low, do something undemanding, and go back when you feel sleepy.

This feels counterproductive and it's one of the better-supported behavioural techniques there is. The reasoning is associative: hours spent lying in bed frustrated and awake teach your brain that bed is a place for lying awake and being frustrated. Getting up breaks that association.

Don't clock-watch while you do it. Estimate.

5. Slow your breathing

Techniques like 4-7-8 breathing — inhale four, hold seven, exhale eight — get recommended constantly. The general principle is sound: extending your exhale relative to your inhale shifts you towards parasympathetic activation, which is the state you need to be in to fall asleep.

The specific numbers are not magic. Any pattern with a longer out-breath than in-breath does the same job. If 4-7-8 feels like breath-holding rather than relaxing, use something gentler — in for four, out for six.

The honest framing: this is a moderate effect that helps when the problem is a racing mind. It won't overcome an inconsistent schedule or a bright room.

6. Deal with screens sensibly

The standard advice is no screens for an hour before bed. Most people won't do this, so here's the more useful version.

There are two separate problems with a phone at bedtime, and they're not equally important. The light matters, but a phone at arm's length delivers far less light than a lit room, and night mode reduces it further. The bigger problem is content. Doomscrolling, work email, and group chats are cognitively and emotionally activating, and activation is the actual enemy.

So: if you're going to use a screen, be deliberate about what's on it. A book on an e-reader at low brightness is fine. Twenty minutes of news before you close your eyes is not.

What doesn't deserve the airtime it gets

  • Sleep-specific supplements and sprays. Some have evidence, most are marketed far beyond it. Melatonin is prescription-only in the UK and is genuinely useful for jet lag and some circadian disorders — it's not a general sedative.
  • Complicated bedtime routines. A routine helps mainly through consistency. A twelve-step ritual isn't twelve times better than a three-step one, and it's harder to sustain.
  • "Just relax." If this worked, you wouldn't be reading an article about it.

If none of it works

Persistent trouble falling asleep — most nights, for a month or more, with real daytime impact — is insomnia, and it's treatable. The first-line treatment recommended in the UK is CBT-I, cognitive behavioural therapy for insomnia, not medication. It's available through the NHS and through digital programmes. Talk to a GP.

The cumulative cost of chronically short sleep is also worth taking seriously, and we've written about that side of it in sleep debt is real, and it's affecting your mental health more than you think.

Frequently asked questions

How long should it take to fall asleep?

Roughly 10 to 20 minutes is typical. Consistently much longer suggests an issue worth addressing. Consistently under five minutes can indicate you're significantly sleep-deprived.

Does the 4-7-8 method work?

The principle — a long exhale — is sound. The specific count isn't special. Any pattern with a longer out-breath than in-breath does the same thing.

Does a sleep mask help you fall asleep faster?

It helps by removing light, which is one of the main things keeping people alert. If your room is already properly dark it adds little. If it isn't, it's the fastest fix available.

What temperature should my bedroom be?

Cooler than a living room. Commonly cited guidance sits around 16–19°C, though that's a general recommendation rather than a fixed rule — adjust to your own comfort.
