What is insomnia?

Short-term and long-term trouble sleeping, explained simply. Tap a card.

Insomnia means having trouble falling asleep, staying asleep, or getting good-quality sleep, even when you have the chance to rest. It is one of the most common sleep problems.

Almost everyone has nights when sleep doesn’t come easily. Sleep problems become worth looking into when they keep happening and start to affect your days.

Having some of these experiences doesn’t mean you have a sleep disorder. People are complex, and only a qualified professional can assess what’s going on for you. Please talk to your clinical provider or therapist.
🌤️ Short-term trouble sleepingA few rough days or weeks, often after stress or change.
Read more

Short-term insomnia can last a few days or weeks. It is often set off by stress or by changes in your schedule or surroundings, like a new job, a move, a loss or travel.

It often settles once the stress passes or you adjust. Gentle habits help stop it from turning into a long-term pattern: keep your wake time steady, avoid long lie-ins and late naps, and don’t lie in bed fighting sleep.

Even after a bad night, try to get up at your usual time. It protects tomorrow night’s sleep.
🌘 Long-term (chronic) insomniaTrouble sleeping 3 or more nights a week for more than 3 months.
Read more

NHLBI describes chronic insomnia as trouble sleeping that happens 3 or more nights a week, lasts more than 3 months, and isn’t fully explained by another health problem.

Over time, insomnia can keep itself going. Worrying about getting enough sleep can make it worse, and habits like lying awake in bed can teach your brain that bed is a place for being awake.

Chronic insomnia has been linked to a higher risk of high blood pressure, heart disease and diabetes. The hopeful part: it can be treated, and CBT for insomnia is usually the first choice.

You don’t have to just live with it. Long-term insomnia is a real health problem with real help available.
🕰️ Trouble falling asleepLying awake for a long time before sleep comes.
Read more

Trouble falling asleep is very common. In 2020, about 1 in 7 U.S. adults (14.5%) had trouble falling asleep most days or every day. It was more common in women than men.

Common reasons

  • Stress, anxiety or low mood
  • Caffeine, alcohol or nicotine
  • A noisy, bright, too-warm or uncomfortable room
  • Screens right before bed
  • An irregular schedule, jet lag or shift work

The harder you try to force sleep, the more awake you can feel. Habits that calm your body and teach your brain that bed means sleep usually help most.

See “When your mind won’t switch off” below, and “Sleep habits that help” in the Sleep & mental health guide, for things to try tonight.
🌗 Waking up in the night or too earlyWaking often, or waking hours before you need to.
Read more

In 2020, about 1 in 6 U.S. adults (17.8%) had trouble staying asleep most days or every day. It becomes more common in midlife and later life.

Waking up can be caused by stress, alcohol (which makes sleep lighter and more broken), needing the bathroom, pain, or changes like menopause.

What can help

  • Limit drinks close to bedtime
  • Avoid alcohol in the evening
  • Keep the room cool, dark and quiet
  • If you’re awake and frustrated, get up and do something calm in dim light until sleepy
If you keep waking early and feel low or hopeless, please talk to your clinical provider. Early waking can go along with low mood.

What can make sleep hard?

Stress, worry, schedules, surroundings and more. Tap a card.

Insomnia rarely has just one cause. Stress, life changes, habits, your surroundings and your health can all play a part. Knowing your own mix can help you choose what to change first.

🌪️ Stress and big life eventsWorries about school, work, money or loss can keep you awake.
Read more

Stress about school, work, relationships or money raises the risk of insomnia, and so does the death of a loved one. Hard times often show up in sleep first.

What can help

  • Talk it through with someone you trust during the day
  • Try the “Worry dump” worksheet about an hour before bed
  • Use slow breathing or a body scan in bed
  • Keep your wake time steady while things settle
If you’re grieving, the “Grief: understanding loss” guide explains why loss can upset sleep, appetite and energy.
🔁 Worrying about sleep itselfFear of a bad night can cause a bad night.
Read more

Worrying about getting enough sleep can raise the risk of insomnia or make it worse. The more you try to force sleep, the more awake you can feel.

Easing this worry is one of the main parts of CBT for insomnia. Small shifts help, like turning the clock around and reminding yourself that resting quietly is still kind to your body.

Try the “Sleep thoughts reframe” worksheet to catch and soften a worried sleep thought.
🗓️ Your scheduleShift work, travel and irregular routines confuse your body clock.
Read more

Shift or night work, frequent travel across time zones, and irregular bed and wake times can all throw off your body’s sleep-wake cycle.

A steady wake time, every day, is one of the strongest signals you can give your body clock.

The Nightmares, shift work & sleep problems guide has practical tips for shift work and jet lag.
🔦 Your surroundingsNoise, light and temperature matter more than we think.
Read more

Noise, light and an uncomfortable temperature can all make it harder to sleep. So can an uncomfortable bed.

Small fixes

  • Earplugs or a fan for steady background sound
  • Thick curtains, blinds or an eye mask
  • A comfortably cool room, with covers you can adjust
  • Phone charging outside the bedroom
☕ Caffeine, alcohol and nicotineThey can quietly break up your sleep.
Read more

Caffeine’s effects can last up to 8 hours, so an afternoon coffee can still keep you awake at bedtime. Nicotine is a stimulant too.

Alcohol may make you drowsy at first, but it makes sleep lighter and more broken later in the night.

The Sleep & mental health guide has a “Caffeine and alcohol timing log” worksheet to spot your own patterns.
🧬 Age, sex and family historySome people are more likely to have insomnia.
Read more

Insomnia can happen at any age, but the chances rise as you get older. It is more common in women than in men, and hormone changes in pregnancy and menopause can disrupt sleep. It can also run in families.

In 2020, trouble falling asleep most days was more common in U.S. women (17.1%) than men (11.7%), and trouble staying asleep became more common with age.

Mental and physical health can affect sleep too. The next section looks at trauma, ADHD, pain, pregnancy and menopause.

Sleep alongside other struggles

How trauma, ADHD, pain, pregnancy and menopause affect sleep.

Sleep is often one of the first things to change when life or health gets hard. Many conditions affect sleep, and poor sleep can make those conditions feel heavier. Looking after sleep can be one part of caring for the bigger picture.

For anxiety and low mood, see “How sleep and mental health connect” in the Sleep & mental health guide, and the “Anxiety: understanding it” and “Depression: understanding it” guides. The cards below cover some other common situations.

🛡️ After traumaNightmares and feeling on guard can make bedtime feel unsafe.
Read more

The U.S. National Center for PTSD says almost everyone who has PTSD also has trouble sleeping. Nightmares can replay what happened, and some people put off going to bed because the night feels unsafe. Feeling on guard or easily startled makes deep rest hard.

CBT for insomnia is recommended as a first-choice treatment for sleep problems with PTSD. The VA says it improves sleep for about 7 in 10 people who complete it, and can reduce how often nightmares happen and how upsetting they are.

Some people use alcohol or other drugs to get to sleep. Over time this tends to make sleep and health worse.

The Healing from trauma guide has grounding skills for after a nightmare, and the “Nightmare rewrite” worksheet in the Nightmares, shift work & sleep problems guide can help you practise a calmer ending.
⚡ ADHDBusy minds and later body clocks can make bedtime hard.
Read more

Sleep problems and ADHD often go together. A 2016 review of studies in teens found links between poor sleep and ADHD symptoms, and between poor sleep and harder days at school and at home. The authors noted that the research is still limited.

Ideas people find useful

  • A visual bedtime routine with the same steps each night
  • Alarms or reminders to start winding down
  • A “parking lot” notebook for ideas that pop up at bedtime
  • Physical activity earlier in the day
  • Morning light and a steady wake time
See the Everyday ADHD strategies guide for more on daily routines. If sleep is a big struggle, talk to your clinical provider.
🩹 Chronic painPain disturbs sleep, and poor sleep can turn pain up.
Read more

Sleep and pain affect each other. A 2013 research review found that sleep problems reliably predict new and worsening chronic pain, and that poor sleep may predict pain even more strongly than pain predicts poor sleep.

That means improving sleep is a hopeful way in, even when pain itself is hard to change. CBT for insomnia and relaxation skills can help people living with pain.

The Chronic pain guide has pacing and coping tips that fit well with the sleep habits here.
🤰 PregnancyBody changes, a growing bump and worries can disturb sleep.
Read more

Hormone changes can bring tiredness, especially in the first 12 weeks. Later, a growing bump can make it hard to get comfortable, and you may need the toilet more often. Strange dreams about the baby or birth are common too.

From 28 weeks, the NHS says the safest position to go to sleep is on your side, either left or right. If you wake on your back, just roll onto your side again. Pillows under your bump and between your knees can help.

Other tips

  • Rest when you can, and accept help
  • Avoid tea, coffee and cola in the evening
  • Avoid napping in the late afternoon or evening
  • Try breathing or relaxation before bed
  • Talk about worries with your partner or midwife
If poor sleep comes with feeling hopeless or losing interest in things, tell your doctor or midwife. Help is available.
🌡️ MenopauseNight sweats and hormone changes can break up sleep.
Read more

Around menopause, many women find it hard to get to sleep or stay asleep. Hot flushes at night, called night sweats, can make this worse. Poor sleep can leave you feeling irritable, stressed or anxious, and mood symptoms can feel worse when you’re very tired.

Ideas

  • Keep the bedroom cool and use layers you can throw off
  • Keep a fan or a glass of water by the bed
  • Track sleep and mood to spot patterns to share with your provider
See the Women’s mental health guide for more on menopause and mood. For questions about treating symptoms, consult with your clinical provider.

When your mind won’t switch off

Simple ways to quiet racing thoughts at night.

Bedtime is often the first quiet moment of the day, so worries rush in. Worrying about unfinished tasks is a big reason people struggle to fall asleep. When your head is full of “don’t forget…”, your brain stays on alert.

📝 Write a worry list or to-do listGet it out of your head and onto paper.
Read more

In a sleep-lab study, 57 young adults spent 5 minutes before bed either writing a to-do list for the next few days, or writing about tasks they had already done. The to-do list group fell asleep faster. The more specific their list, the faster they fell asleep.

Try it

  1. About an hour before bed, grab paper or the Worry dump worksheet.
  2. Write down everything on your mind: tasks, worries, reminders.
  3. For each one, write one small next step, or “not tonight”.
  4. Close the notebook. Tell yourself: “It’s written down. I can deal with it tomorrow.”
The study was in healthy young adults, so it may not work for everyone. It’s free and safe to try.
🌬️ Slow breathingCalm your body so your mind can follow.
Read more

Relaxation is a key part of CBT for insomnia. Slow breathing gently calms the body’s stress response, which makes it easier to drift off.

Box breathing

  1. Breathe in slowly through your nose for a count of 4.
  2. Hold gently for 4.
  3. Breathe out slowly for 4.
  4. Hold for 4.
  5. Repeat for a few minutes, letting your body sink into the bed.
Our Breathing guide has more breathing exercises to try in bed.
🧘 Relax your bodyLet go of tension, one part at a time.
Read more

Relaxation and meditation skills help you wind down. A body scan is an easy one to try lying down.

Simple body scan

  1. Lie comfortably and close your eyes.
  2. Notice your feet. Squeeze them gently, then let go.
  3. Move slowly up: legs, tummy, hands, shoulders, face.
  4. At each part, breathe out and let it soften.
  5. If your mind wanders, gently come back to where you were.
🚪 Get up if you can’t sleepDon’t lie there fighting it.
Read more

If you’ve been lying awake for a while and feel frustrated, get up. Go to another room and do something calm in dim light, like reading or listening to quiet music. Go back to bed when you feel sleepy.

This might sound strange, but it stops your brain linking bed with frustration and worry. It’s one of the main parts of CBT for insomnia.

Avoid checking the clock. Watching the minutes tick by only adds pressure. Turn the clock around.
💭 Talk back to sleep worriesEase the fear of not sleeping.
Read more

Worrying about not sleeping can keep you awake. Part of CBT for insomnia is easing this worry.

Kinder thoughts to try

  • “Resting quietly is still good for me.”
  • “I’ve managed after bad nights before.”
  • “Sleep will come when my body is ready.”
If racing thoughts at night are about hurting yourself or not wanting to be here, please reach out now. Call or text 988 (U.S.), or text HOME to 741741.

CBT for insomnia (CBT-I)

The first-choice treatment for long-term sleep trouble, explained.

Cognitive behavioural therapy for insomnia, or CBT-I, is a talking and practical therapy that helps you change the thoughts and habits that keep you from sleeping. It’s usually the first-choice treatment for long-term insomnia.

CBT-I is usually a structured plan lasting 6 to 8 weeks. It can be given by a doctor, nurse or therapist, in person, by phone or online. There are also online self-help programmes.

💭 Thinking differently about sleepEasing worry and pressure about sleep.
Read more

This part, called cognitive therapy, helps reduce anxiety about not sleeping. You learn to notice unhelpful thoughts, like “If I don’t sleep 8 hours, tomorrow will be a disaster”, and replace them with more balanced ones.

Less pressure on sleep often means sleep comes more easily.
🛏️ Stimulus controlRebuilding the link between bed and sleep.
Read more

Stimulus control strengthens your brain’s link between bed and sleep. You go to bed only when sleepy, get up if you can’t sleep, and use your bed only for sleep and sex.

⏳ Sleep restrictionLess time in bed at first, to build stronger sleep.
Read more

This sounds odd, but it works. You limit your time in bed to a set window, close to how long you actually sleep now. This builds up your natural sleep drive. As your sleep improves, the window gets longer.

Sleep restriction can make you sleepier at first, so it’s best done with guidance from a trained professional. Take extra care with driving.
🧘 RelaxationSkills to calm your body and mind.
Read more

You learn relaxation or meditation skills to help you wind down, such as slow breathing and relaxing your muscles.

📚 Sleep educationLearning healthy sleep habits.
Read more

You learn how sleep works and which habits help, like a steady schedule, a dark and quiet room, and cutting back caffeine and alcohol.

📓 Keeping a sleep diaryTracking your sleep to spot patterns.
Read more

A health care provider may ask you to keep a sleep diary, a simple record of when you go to bed, when you wake, and how you feel. It helps you and your provider see patterns.

Use the Sleep tracker in Tools, or the “My sleep diary” worksheet in the Sleep & mental health guide, and bring it to your appointment.
🔎 Where to find CBT-IThrough a provider, a therapist or an online programme.
Read more

Ask your clinical provider about a referral to someone trained in CBT-I. It can be given by a doctor, nurse or therapist, in person, by phone or online, and there are online self-help programmes too.

The U.S. Department of Veterans Affairs offers a free app called Insomnia Coach. It is based on CBT-I, made for everyone (not only Veterans), and has a weekly training plan and a sleep diary. It doesn’t replace care from a professional.

The VA suggests checking with a provider first if you have certain conditions, such as sleep apnea, and notes the app may not suit people who work nights. A related VA app, CBT-i Coach, is designed to be used alongside CBT-I with a provider.

Veterans can also ask their VA care team about CBT-I.
For any other treatment options, please consult with your clinical provider.

Sleep trackers and wearables

What they can tell you, what they can’t, and when to take a break.

Watches, rings, phone apps and bedside devices promise to show how you slept. They can be a helpful nudge to take sleep seriously. But the numbers are estimates, and paying too much attention to them can backfire.

🎯 What they get rightMany are fairly good at telling sleep from wake.
Read more

A 2021 sleep-lab study tested seven consumer sleep trackers against a full overnight sleep study in 34 healthy young adults. Most devices were good at detecting when people were asleep, and many did as well as or better than the movement monitors researchers use.

Over weeks, a tracker can help you notice patterns, like later bedtimes on weekends or shorter sleep after late screen time.

❓ What they often missSleep stages and wake time are much less reliable.
Read more

In the same study, devices were weaker at spotting when people were awake, their sleep-stage results were inconsistent, and they tended to do worse on nights when sleep was broken. That’s exactly the kind of night people worry about most.

A full sleep study measures brain waves. Most wearables guess your stages from movement and heart rate, so a “low deep sleep” score may not be accurate.

How you feel during the day is often a better guide than a score. Feeling rested and able to function matters more than hitting a number.
🔍 When tracking becomes stressfulChasing a perfect score can make sleep worse.
Read more

Sleep researchers coined the word “orthosomnia” for people who become so focused on perfect tracker data that it adds stress. In a 2017 report, they described patients who sought help because their tracker showed light or restless sleep, and who trusted the device more than proper sleep tests.

Worry and pressure about sleep are among the things that keep insomnia going. Checking your score first thing every morning can set the tone for the whole day.

Signs to take a break

  • You feel anxious before bed about what your score will be
  • A bad score ruins your mood even when you feel okay
  • You change plans or cancel things because of a number
  • You check the app in the night
🧘 Using trackers kindlyLet data serve you, not stress you.
Read more

Try this

  • Look at weekly trends, not single nights
  • Hide or ignore sleep-stage scores
  • Check in with how you feel before you look at the data
  • Try a week off and notice how you feel
  • Bring trends, not scores, to your clinical provider

Researchers suggest including tracker use in CBT for insomnia, so people can learn to use the data in a helpful way.

The Sleep tracker in Tools is a simple diary: you note how you slept and felt, and it shows patterns. No scores to chase.

Supporting someone with insomnia

How to help a partner, friend or family member who can’t sleep.

Living with someone who can’t sleep can be hard on both of you. You can’t sleep for them, but you can take the pressure off and make it easier for them to follow the steps that help.

🪶 Take the pressure offWorry about sleep keeps insomnia going.
Read more

Worrying about getting enough sleep can make insomnia worse. Well-meant questions and advice can add to that pressure.

Try this

  • Ask how their day is going, not only how they slept
  • Avoid comparing (“I was out like a light”)
  • Don’t suggest extra time in bed to catch up
  • Notice small wins, like a steadier wake time

Things that usually don’t help

  • “Just relax.”
  • “Just go to bed earlier.”
  • Asking “Did you sleep?” every single morning
🧩 Back their CBT-I planSome steps look strange but work.
Read more

CBT for insomnia asks people to get out of bed when they can’t sleep, keep a fixed wake time, and sometimes spend less time in bed at first. These steps can look odd from the outside.

Ways to help

  • Keep a comfy chair and a dim lamp ready in another room
  • Join them for a morning walk in daylight
  • Keep evenings calm and screens low
  • Help with the sleep diary only if they ask
Shortening time in bed can make people sleepier at first. Offer to drive if they’re very tired.
🛏️ Sharing a bed or a homeDifferent nights, same household.
Read more

If one of you lies awake or gets up in the night, both can lose sleep. Agree on a plan together at a calm time, not at 3 a.m.

Ideas

  • Agree that getting up quietly in the night is okay and expected
  • Use earplugs or an eye mask if lights or movement wake you
  • Keep the bedroom cool, dark and quiet for both of you
  • Sleeping in separate rooms for a while is okay. It’s not a sign the relationship is in trouble
🧭 When to nudge toward helpWeeks of poor sleep deserve a proper check.
Read more

If trouble sleeping goes on for weeks, or starts to affect their mood, work or safety, gently encourage them to talk to their clinical provider. Offer to help book the appointment or go with them.

If they talk about feeling hopeless or not wanting to be here, don’t wait. Call or text 988 together (U.S.), or text HOME to 741741.
🔋 Look after your own sleepSupporters need rest too.
Read more

Supporting someone through broken nights can leave you running on empty. Your own sleep matters just as much.

Ideas

  • Protect a short wind-down for yourself
  • Take turns with night-time duties where you can
  • Ask family or friends for a night off
  • Talk to someone you trust about how you’re feeling

By the numbers

Trouble sleeping is very common. You are not alone.

What helps

7 in 10people with PTSD who complete CBT for insomnia sleep better, according to the VA’s National Center for PTSD.
6–8 weeksis the usual length of a structured CBT-I plan (NHLBI).

When to get help for insomnia

Signs it’s time to talk to a clinical provider.

Many short spells of poor sleep settle with time and new habits. If trouble sleeping keeps going, there is real help available. You don’t have to just put up with it.

Talk to your clinical provider if…

  • Changing your sleep habits hasn’t helped
  • Poor sleep is affecting your daily life, mood or ability to cope
  • Trouble sleeping happens 3 or more nights a week, or has lasted for months
  • You feel very sleepy during the day, or snore loudly
  • You keep waking very early and feel low

Your provider will try to find what’s causing the problem. They may ask you to keep a sleep diary, refer you for CBT-I, or suggest a sleep study if they think another sleep condition might be involved.

Bring two weeks of notes from the Sleep tracker or a sleep diary, plus the “Questions for my clinical provider” worksheet. For any other treatment options, please consult with your clinical provider.
If you’re in crisis, call or text 988 (U.S.), or text HOME to 741741. If a life is in danger, call 911. Outside the U.S., findahelpline.com lists free, confidential helplines in many countries.
