The short answer The methods with the best evidence are unglamorous: get out of bed if you’re still awake after about 20 minutes, stop caffeine by early afternoon, skip the nightcap and wake up at the same time every day. For tonight, a warm shower an hour or two before bed, a five-minute to-do list and a relaxation exercise in bed are your best quick bets.
Below are 12 methods, ranked by how strong the research behind them is, not by how popular they are online. The grade tells you how much proof exists. It doesn’t tell you whether a method will work for you, so treat the bottom half as cheap experiments.
| Rank | Method | Evidence | What the research found |
|---|---|---|---|
| 1 | Get up if you can’t sleep (stimulus control) | Strong evidence | Recommended by the American Academy of Sleep Medicine for chronic insomnia; a core part of cognitive behavioral therapy for insomnia |
| 2 | Stop caffeine by early afternoon | Strong evidence | Caffeine added about 9 minutes to the time it took to fall asleep across 24 studies |
| 3 | Skip alcohol close to bedtime | Strong evidence | Speeds sleep onset, then disrupts the second half of the night |
| 4 | Same wake-up time every day | Moderate evidence | Part of the guideline-backed stimulus control instructions |
| 5 | Progressive muscle relaxation | Moderate evidence | Relaxation therapy carries a conditional AASM recommendation |
| 6 | Warm shower or bath 1 to 2 hours before bed | Moderate evidence | Meta-analysis of 17 small studies linked it to falling asleep faster |
| 7 | Mindfulness meditation | Moderate evidence | Beat sleep hygiene classes in a randomized trial in older adults |
| 8 | Write a to-do list at bedtime | Limited evidence | One lab trial of 57 young adults: list-writers fell asleep faster |
| 9 | Paradoxical intention (try to stay awake) | Limited evidence | Older trials; rated effective by the AASM in 2006, not reviewed in 2021 |
| 10 | Imagery distraction or cognitive shuffling | Limited evidence | One small study of people with insomnia found a shorter time to sleep |
| 11 | Cool, dark, quiet bedroom | Limited evidence | Widely recommended; little direct proof it speeds sleep onset |
| 12 | Slow breathing, including 4-7-8 | Weak evidence | Calming, but the 4-7-8 count itself has barely been studied for sleep |
Tonight’s plan
If you want one routine instead of twelve options, this one stacks the methods that have the most support and cost nothing.
- Set your wake-up time first. Pick the time you’ll get up tomorrow and every day after, weekends included. Count back 7 to 8 hours for a target bedtime, or use the sleep calculator.
- Check your last caffeine. If you had coffee within about 9 hours of bed, expect it to cost you some sleep tonight and move tomorrow’s cutoff earlier.
- Shower or bathe 1 to 2 hours before bed. Warm, not scalding. Ten minutes is enough.
- Spend five minutes on tomorrow’s to-do list. Be specific. Then put the paper away.
- Go to bed only when you feel sleepy. Lights out, room cool and dark.
- Run a relaxation exercise in bed. Progressive muscle relaxation or slow breathing, with no goal except doing it.
- Still awake after roughly 20 minutes? Get up. Go to another room, keep the lights low, do something dull and screen-free, and come back when you’re sleepy. Repeat as needed. Don’t watch the clock to time it; estimate.
The 12 methods, from strongest evidence to weakest
1. Get out of bed when you can’t sleep
This sounds backward, and it’s the method with the most backing. The idea, called stimulus control, is to stop your brain from linking the bed with frustration. The American Academy of Sleep Medicine’s 2021 guideline suggests stimulus control as a stand-alone treatment for chronic insomnia, and it’s one piece of cognitive behavioral therapy for insomnia, the treatment the same guideline strongly recommends.
The AASM’s patient advice is plain: if you don’t fall asleep after 20 minutes, get out of bed, do a quiet activity without much light and skip electronics. Use the bed only for sleep and sex. The first few nights can be rough. It works by repetition, not on night one.
2. Stop caffeine by early afternoon
A 2023 meta-analysis of 24 studies found caffeine added about 9 minutes to the time it took to fall asleep and cut total sleep by 45 minutes. To avoid losing sleep, the authors calculated that a regular coffee should be finished at least 8.8 hours before bed. For an 11 pm bedtime, that’s roughly 2 pm.
An earlier trial gave people 400 mg of caffeine at bedtime, 3 hours before or 6 hours before. Even the 6-hour dose cut objectively measured sleep by more than an hour. Participants’ own sleep diaries didn’t reliably pick up the 6-hour effect; only the sleep monitor did. That’s why caffeine is easy to overlook as the cause. Our caffeine calculator estimates how much is still in your system at bedtime, and how long caffeine stays in your system covers the details.
3. Skip the nightcap
Alcohol does help you fall asleep faster. That’s the trap. A review of every known study in healthy volunteers found that at all doses, alcohol shortens the time to fall asleep but increases sleep disruption in the second half of the night. You trade a quicker start for a worse 3 am. The AASM lists avoiding alcohol before bedtime among its basic habits.
4. Wake up at the same time every day
A fixed wake time is part of the standard stimulus control instructions, and the AASM’s advice is to get up at the same time every day, even on weekends. It works on tonight’s sleep indirectly: sleeping in after a bad night pushes back the time you’ll feel sleepy the next evening. Keep the alarm, skip the long recovery nap, and the pressure to sleep builds on schedule. Not sure what time to aim for? See what time you should go to bed.
5. Progressive muscle relaxation
You tense one muscle group, hold it, then let it go, working through your body. The AASM guideline suggests relaxation therapy as a stand-alone insomnia treatment, though NIH’s complementary health center notes that relaxation alone has a small amount of low-quality evidence behind it. It’s safe and free, which is why it ranks this high.
A simple version, adapted from an NHS guide: squeeze a muscle group, count to five, release, and notice the difference for a few breaths. Go feet, calves, thighs, stomach, hands, arms, shoulders, face. Tense firmly, never to the point of pain.
6. A warm shower or bath 1 to 2 hours before bed
A meta-analysis of 17 studies found that water at about 104 to 109°F (40 to 42.5°C), taken 1 to 2 hours before bed for as little as 10 minutes, was linked to falling asleep significantly faster and better self-rated sleep. The likely reason: warming your skin pushes blood to your hands and feet, which helps your core temperature drop afterward, and that drop is part of how your body starts sleep. The authors called the evidence limited, especially on ideal timing. Timing matters, so a shower right before lights out isn’t the same thing.
7. Mindfulness meditation
In a randomized trial of 49 older adults with moderate sleep problems, six weeks of mindfulness classes improved sleep quality more than a structured sleep hygiene course, and insomnia symptoms and fatigue improved too. This is a skill you build over weeks, not a switch. A short body scan in bed is a reasonable way to start.
8. Write a to-do list for tomorrow
In a sleep-lab study, 57 young adults spent five minutes before bed writing either a to-do list for the next few days or a list of what they’d already finished. The to-do group fell asleep significantly faster, and the more specific their lists, the faster they fell asleep. It’s one study of healthy students, so the grade stays limited. It’s also nearly effortless, which makes it worth trying if unfinished tasks are what keep you up.
9. Paradoxical intention
You lie in bed in the dark and gently try to stay awake, without screens or reading. For some people, removing the effort to fall asleep removes the anxiety that was blocking it. The AASM’s 2006 review rated paradoxical intention individually effective for chronic insomnia at its middle level of certainty. The 2021 guideline didn’t include it, and few modern trials exist. Worth a try if “trying hard to sleep” describes your nights.
10. Imagery distraction and cognitive shuffling
Instead of fighting worried thoughts, you give your mind a task that’s absorbing but low-stakes. In a study of 41 people with insomnia, those trained to distract themselves with detailed imagery fell asleep faster than those given no instructions, while generic “just distract yourself” advice didn’t help. Cognitive shuffling is a cousin: pick a word, then picture unrelated things that start with each of its letters. Its direct evidence comes mostly from its creator’s group, so we rate it with the imagery research. Step-by-step instructions are in our cognitive shuffling guide.
11. A cool, dark, quiet bedroom
Sleep organizations recommend it, and the AASM says to keep the room at a comfortable, cool temperature. A Cleveland Clinic sleep psychologist suggests 60 to 67°F (15 to 19°C). Light matters for more than comfort: in a lab study, one night of sleeping in moderate room light raised heart rate and next-morning insulin resistance compared with a dim room.
So why rank it low? Because there’s little direct research showing that fixing the room makes you fall asleep faster. It’s still worth doing, since it removes obstacles. See the best temperature for sleep for the details.
12. Slow breathing, including 4-7-8
The 4-7-8 pattern (in for 4 counts, hold for 7, out for 8) is all over the internet, but it has very little direct sleep research behind it; most studies are small trials in hospital patients. Slow breathing in general is a reasonable relaxation tool. The NHS version is simple: breathe in gently while counting from 1 to 5, then out for the same count, for at least five minutes. If holding your breath for seven counts makes you tense, skip the hold.
What about the military method and melatonin?
The military method claims you can fall asleep in two minutes by combining muscle relaxation, breathing and a calming image. Cleveland Clinic notes there’s no scientific evidence it works. Its parts overlap with methods 5, 10 and 12, so it’s harmless to try. Our military sleep method guide walks through it.
Melatonin isn’t a method so much as a supplement, and the numbers are modest. A meta-analysis of 19 trials found it shortened the time to fall asleep by about 7 minutes on average. The AASM suggests against melatonin for chronic insomnia (a weak recommendation), though it has real uses for jet lag and body-clock problems. If you’re considering it, read our melatonin dosage guide first.
How long should it take to fall asleep?
Most people without sleep problems fall asleep within 10 to 20 minutes, and Cleveland Clinic says even 45 minutes can be fine.
So the goal isn’t “instantly.” It’s reliably, within a normal window, without a fight.
Why you can’t fall asleep even when you’re tired
Being tired and being sleepy aren’t the same. You can feel drained and still be too wired to drop off. Common culprits are a racing mind, caffeine still in your system, a bedtime set earlier than your body clock wants, or a long nap. Also common: a bed you’ve learned to associate with lying awake, which is exactly what methods 1 and 4 fix.
If you woke during the night rather than at bedtime, the same rules apply with a few tweaks. See how to fall back asleep.
When to see a doctor
- Trouble sleeping at least three nights a week for three months or more is the definition of chronic insomnia. Ask about cognitive behavioral therapy for insomnia, which the AASM strongly recommends as the main treatment.
- Loud snoring, gasping or pauses in breathing, or heavy daytime sleepiness can point to sleep apnea. That needs an evaluation.
- If you’re drowsy behind the wheel, pull over. Sleepiness while driving is a reason to see a doctor soon.

Common questions
What is the fastest way to fall asleep?
There's no proven way to fall asleep instantly. The best-supported approach is to go to bed only when sleepy, get up if you're still awake after about 20 minutes, avoid caffeine for roughly 9 hours before bed, and use a relaxation exercise once you're in bed.
Does the military method really work in 2 minutes?
There's no scientific evidence for the two-minute claim. The method combines muscle relaxation, slow breathing and a calming image, which overlap with techniques that have some support, so it's fine to try.
Should I get out of bed if I can't fall asleep?
Yes. The American Academy of Sleep Medicine advises getting up after about 20 minutes, doing something quiet in low light without screens, and returning to bed when you feel sleepy.
How long should it take to fall asleep?
Most people without sleep problems fall asleep within 10 to 20 minutes. If it regularly takes much longer, at least three nights a week for three months, talk to a doctor about insomnia and cognitive behavioral therapy for insomnia (CBT-I).
