The fastest reliable way to fall asleep is to go to bed only when you feel sleepy. Then use a simple relaxation technique, such as slow breathing or a calm mental picture. If you are still awake after about 20 minutes, get up.
Four methods have the best research behind them: relaxation training, getting out of bed when you cannot sleep (stimulus control), paradoxical intention, and a warm bath or shower 1 to 2 hours before bed. The military method, 4-7-8 breathing and the cognitive shuffle are low-risk and worth a try. But they have had little or no direct research on sleep.
This page is about techniques: what to do tonight. If you lie awake most nights and want to know why, start with why you can’t fall asleep. It covers the common causes, from a late body clock to caffeine and screens. If the problem has lasted for months, read our insomnia overview and how CBT-I treats it.
How Long Should It Take To Fall Asleep?
The time it takes to fall asleep is called sleep latency. A healthy latency is usually 15 to 20 minutes. Count it from when you settle down to sleep, not from when you start getting ready for bed.
Taking less than 10 minutes may mean you are sleep-deprived. Regularly taking too long is a symptom of insomnia (Sleep Foundation). Health conditions, medicines, sleep disorders and your bedtime routine can all make it harder to drop off (Sleep Foundation).
So the realistic goal is not to fall asleep in 2 minutes. It is to stop lying awake for 30, 60 or 90 minutes. The sleep calculator assumes about 15 minutes to fall asleep when it suggests a bedtime. If you usually take longer, add that time so you still get a full night.
The 12 Techniques Compared
The evidence column shows what the research we read actually found. “Guideline-backed” means a clinical guideline supports it for chronic insomnia. “Some evidence” means at least one trial or review found a benefit on falling asleep. “Little research” means we could not find studies testing it on sleep.
| Technique | Best for | Time to learn | Evidence for sleep |
|---|---|---|---|
| 1. Get out of bed after about 20 minutes (stimulus control) | Lying awake, frustration in bed | None, but takes discipline | Guideline-backed for chronic insomnia |
| 2. Progressive muscle relaxation | Physical tension | A few nights of practice | Guideline-backed as relaxation therapy; low-quality evidence on its own |
| 3. Paradoxical intention (try to stay awake) | Pressure to sleep, “trying too hard” | One night | Some evidence: meta-analysis of 10 trials, stronger studies needed |
| 4. Warm bath or shower 1 to 2 hours before bed | Planning ahead in the evening | None | Some evidence: meta-analysis of 13 studies, limited research overall |
| 5. Five-minute to-do list at bedtime | Worry about tomorrow’s tasks | None | Some evidence: one lab study in healthy young adults |
| 6. Imagery distraction and guided imagery | Racing or unwanted thoughts | A few nights | Mixed: one small positive study; a review found no better than placebo |
| 7. Cognitive shuffle | Repetitive worry loops | Minutes | Little research; related to imagery distraction |
| 8. The military method | People who like a fixed script | A few nights | Little research: no sleep studies found |
| 9. 4-7-8 breathing | Feeling anxious or keyed up | Minutes | Little research on sleep |
| 10. Body scan and mindfulness meditation | Stress and a busy mind | Weeks to get good at it | Not enough evidence on its own for insomnia |
| 11. Cool, dark, quiet bedroom | Everyone | One-off setup | Standard advice from sleep experts; part of sleep hygiene |
| 12. Calming music | General relaxation, noisy homes | None | Some evidence for reported sleep quality in insomnia |

Why “little research” is not the same as “useless”. Breathing exercises, body scans and mental games are cheap and low-risk. Relaxation techniques are generally considered safe. A few people report more anxiety or intrusive thoughts while doing them (NCCIH).
Try one for a week before you judge it. Stop any that make you feel worse.
Techniques With The Strongest Evidence
1. Get Out Of Bed After About 20 Minutes
The AASM advises not going to bed unless you are sleepy. If you do not fall asleep after 20 minutes, get out of bed and do a quiet activity without much light. Do not get on electronics (AASM Sleep Education).
Lying in bed stressing about sleep can train your brain to link the bed with being awake and frustrated. Getting up breaks that link (Sleep Foundation). You do not need to watch the clock. A rough sense that you have been awake a while is enough.
This is stimulus control, one of the core parts of cognitive behavioral therapy for insomnia (CBT-I). The rules are simple: go to bed only when sleepy, get out of bed if you cannot sleep, and use the bed only for sleep and sex (NHLBI).
The AASM’s 2021 guideline suggests stimulus control on its own as a treatment for chronic insomnia in adults. It is a conditional recommendation (Edinger 2021).
2. Progressive Muscle Relaxation
Lie down and breathe slowly. Tense one muscle group, such as your face or shoulders, for about 10 seconds, then release it. Work down the body to your feet and skip any painful areas (Sleep Foundation).
The AASM guideline suggests relaxation therapy as a single treatment for chronic insomnia. This is another conditional recommendation (Edinger 2021). NCCIH is more cautious. By themselves, relaxation techniques have a small amount of low-quality evidence for chronic insomnia. They work best as part of CBT-I, which often includes progressive relaxation, abdominal breathing and guided imagery (NCCIH).
3. Paradoxical Intention: Try To Stay Awake
Instead of trying to fall asleep, lie in bed with your eyes open. Calmly tell yourself you will stay awake. The aim is to take away the pressure that keeps a racing mind going (Sleep Foundation).
A 2022 meta-analysis found 10 trials of paradoxical intention for insomnia. Compared with no treatment, it led to large improvements in key insomnia symptoms and in sleep-related performance anxiety. Compared with other active treatments, the gains were smaller but still moderate. The authors said stronger studies are needed before firm conclusions (Jansson-Frojmark 2022).
4. A Warm Bath Or Shower 1 To 2 Hours Before Bed
A 2019 review pooled studies of warm baths and showers before bedtime. Water at about 40 to 42.5 C (104 to 108.5 F), taken 1 to 2 hours before bed for as little as 10 minutes, was linked with falling asleep faster and better self-rated sleep.
The likely reason is that warming the skin helps the body shed heat afterwards, so core temperature drops. The authors noted that research is still scarce, especially on the best timing and length (Haghayegh 2019). This one has to be planned in the evening. It is not a fix at 1 AM.
Techniques For A Racing Mind
5. Write A Five-Minute To-Do List At Bedtime
In a sleep-lab study, 57 healthy adults aged 18 to 30 wrote for 5 minutes before bed. Some wrote a to-do list for the next few days. Others listed things they had already done.
The to-do list group fell asleep significantly faster. The more specific their list, the faster they fell asleep (Scullin 2018). It is one study in young people without insomnia, so treat it as a promising, free experiment. If worry is the main thing keeping you up, see insomnia vs anxiety.
6. Imagery Distraction And Guided Imagery
Guided imagery means recalling a calm memory or picturing a peaceful place in detail. Think of the sights, sounds and smells. Recorded tracks can lead you through it (Sleep Foundation).
The research is mixed. In a small study of 41 people with insomnia, some were taught to distract themselves with an engaging imagery task. They fell asleep sooner and had fewer unwanted thoughts than those given no instructions. General “just think of something else” advice did not help (Harvey and Payne 2002).
But a 2015 review of 7 small studies found that autogenic training or guided imagery shortened the time to fall asleep without beating a placebo. The authors called the results doubtful (NCCIH).
7. Cognitive Shuffle
The cognitive shuffle is a mental game. Pick a random word. For each of its letters, picture a string of unrelated objects that start with that letter. For “bed”, that could be a bicycle, a banana and a boat, then an egg and an eagle, and so on.
The idea is to fill your attention with harmless, random images so worries cannot take hold. We found no published trials of the cognitive shuffle itself. The closest evidence is the imagery distraction study above. It suggests that a specific, absorbing mental task works better than vague efforts to stop thinking (Harvey and Payne 2002).
Body And Breathing Techniques
8. The Military Method
The military method is a short script said to help soldiers fall asleep in about 2 minutes. The steps are:
- Get comfortable and relax each part of your face.
- Drop your shoulders and let your arms rest at your sides.
- Take deep breaths to relax your chest.
- Relax your legs from the hips down to your feet.
- Picture a peaceful setting. If thoughts intrude, notice them and move past them (Sleep Foundation).
Despite its popularity, we could not find any study that tested it. It is a quick body-relaxation exercise plus imagery, so it is a reasonable thing to try. But the 2-minute promise is not backed by research.
9. 4-7-8 Breathing
Breathe out fully through your mouth. Breathe in quietly through your nose for a count of 4, hold for 7, then breathe out slowly through your mouth for 8. Repeat the cycle three or four times (Sleep Foundation).
Slow, deep breathing may activate the parasympathetic nervous system, which is involved in relaxation and sleep (Sleep Foundation).
Direct evidence on sleep is thin. The one controlled study we found measured heart rate and blood pressure in 43 healthy young adults, and both fell after the exercise. It did not measure how quickly they fell asleep (Vierra 2022).
If holding your breath is uncomfortable, shorten the counts or simply breathe out more slowly than you breathe in.
10. Body Scan And Mindfulness Meditation
A body scan is a type of meditation. Lie comfortably and move your attention slowly from your feet to your head. Notice any tension and let it go with each breath (Sleep Foundation). It can take a few weeks before relaxation comes quickly (Sleep Foundation).
The AASM’s 2021 guideline found not enough evidence to make a recommendation on mindfulness by itself for insomnia (NCCIH). Talk to a doctor before starting if you have a history of trauma or if meditation brings up painful thoughts (Sleep Foundation).
Bedroom And Evening Techniques
11. A Cool, Dark, Quiet Bedroom
Your body temperature naturally drops as you sleep, so a cooler room makes it easier to fall and stay asleep. Sleep Foundation puts the best bedroom temperature at about 65 F (18.3 C), give or take a few degrees (Sleep Foundation).
The AASM also advises a quiet, relaxing bedroom at a comfortable, cool temperature. It suggests limiting bright light in the evening and turning off electronic devices at least 30 minutes before bed (AASM). Our sleep hygiene guide covers the full set of habits. 10 bad sleep habits lists the ones most worth dropping.
One caution: the AASM guideline suggests that sleep hygiene should not be the only treatment for chronic insomnia (Edinger 2021). A good bedroom helps. If you lie awake most nights, it is rarely enough by itself.
12. Calming Music
Soothing music can help you relax and mask outside noise. One idea is a playlist that lasts about 15 to 20 minutes, the length of a normal sleep latency (Sleep Foundation).
A 2022 review of 13 studies with 1,007 adults found that music may improve reported sleep quality in people with insomnia. There was not enough good-quality evidence to judge its effect on insomnia severity (NCCIH).
Had coffee after lunch? Caffeine can affect you for 4 to 6 hours (MedlinePlus). The caffeine and sleep calculator estimates how much is still in your system at bedtime.
Which Technique Should You Try First?
- Your body feels tense: progressive muscle relaxation or the military method.
- Your mind will not switch off: a to-do list before bed, then the cognitive shuffle or imagery distraction in bed.
- You feel anxious about not sleeping: paradoxical intention, and turn the clock away.
- You feel wired or short of breath: slow breathing such as 4-7-8.
- You have been awake a while and are getting frustrated: get up, sit somewhere dim and quiet, and return when sleepy.
- You want to plan ahead: a warm bath 1 to 2 hours before bed and a cool bedroom.
A Simple Plan For Tonight
- In the evening: stop caffeine by early afternoon, dim the lights, and put devices away at least 30 minutes before bed (AASM). If you can, take a warm bath or shower 1 to 2 hours before bed.
- Just before bed: spend 5 minutes writing a specific to-do list for tomorrow.
- Go to bed only when sleepy, not just because it is a certain time.
- In bed: pick one technique, such as progressive muscle relaxation or the cognitive shuffle. Stick with it rather than switching every few minutes.
- Still awake after about 20 minutes? Follow the get-up loop above (AASM).
- Tomorrow: get up at your usual time, however the night went. A steady wake-up time every day, even at weekends, steadies your body clock (AASM).
When Techniques Are Not Enough
If you struggle to fall asleep most nights for weeks, quick tricks are unlikely to fix it on their own. CBT-I is a 6- to 8-week program. It is usually recommended as the first treatment for long-term insomnia and can be very effective. It combines relaxation, stimulus control, sleep restriction, sleep education and work on worry about sleep (NHLBI).
The AASM guideline makes a strong recommendation for multicomponent CBT-I for chronic insomnia in adults (Edinger 2021). Our step-by-step insomnia plan shows how those pieces fit together.
When To See A Doctor
- You take a long time to fall asleep at least 3 nights a week and it has gone on for weeks or months.
- Poor sleep is affecting your mood, concentration, work or driving.
- You have an urge to move your legs when you lie down, or you snore loudly or wake up gasping.
- You rely on alcohol, sleep aids or medicines to fall asleep.
If you still have trouble after improving your habits, a healthcare professional can check for a sleep disorder or another condition that is getting in the way (Sleep Foundation).
How To Fall Asleep Fast FAQs
How Can I Fall Asleep In 5 Minutes?
There is no proven way to do it on demand. Going to bed only when sleepy and using a relaxation technique gives you the best chance.
Does The Military Method Really Work In 2 Minutes?
The 2-minute claim has not been tested. The method may help you relax, but no research shows how fast it works.
Is 4-7-8 Breathing Proven To Help You Sleep?
Not directly. Slow breathing can calm the body, and one small study showed lower heart rate and blood pressure afterwards. No trial has measured whether it helps you fall asleep faster.
Should I Stay In Bed If I Cannot Sleep?
No. If you are still awake after about 20 minutes, get up, do something quiet in dim light, and return to bed when you feel sleepy.
What Is The Best Technique If My Mind Is Racing?
Write a specific to-do list before bed. Then use an absorbing mental task such as imagery or the cognitive shuffle in bed. Paradoxical intention helps when the worry is about sleep itself.
Do Sleep Hygiene Tips Work On Their Own?
They help, but sleep experts do not recommend sleep hygiene alone for chronic insomnia. CBT-I is the recommended first treatment for long-term trouble sleeping.
