Better Sleep
Stay Asleep Through the Night
Waking once or several times in the night is common, and many of the causes can be found and eased: alcohol, caffeine, heat, noise, trips to the bathroom, night sweats or breathing problems. This page is about preventing repeated awakenings; falling asleep at bedtime and what to do once you are awake have their own pages.
General information, not medical advice. Last updated October 31, 2026. Written by the AlternativeMed editorial team. Not medically reviewed.
Start here
- Keep alcohol and caffeine well away from bedtime: caffeine for at least 6 hours before bed, and alcohol out of the last few hours.
- Make the bedroom quiet, dark and not too warm, and take note of what actually wakes you (noise, heat, needing the toilet, pain, a partner, a racing mind).
- Keep a simple sleep diary for two weeks and note how many times and roughly when you wake; it shows patterns and is useful to a clinician.
Be careful with
- Do not rely on alcohol or sedating products to stay asleep. Alcohol can make the second half of the night more broken, and sleeping products can interact with medicines and cause next-day drowsiness.
- Loud snoring, gasping or choking, or waking up with a pounding heart or short of breath can point to sleep apnea, which needs a medical check rather than home remedies.
- Never stop or change a prescribed medicine because of night waking; talk with your prescriber, since some medicines can affect sleep.
Get help when
- Waking often most nights for months, or night waking that leaves you struggling in the day (the NHS suggests seeing a doctor in these situations).
- Snoring with gasping, choking or breathing pauses seen by someone else, or being very tired in the daytime.
- Waking often to pass urine, especially with pain or burning, blood in the urine, or great thirst: these need checking.
- An urge to move your legs that returns when you lie down, or drenching night sweats that disturb you often.
- Low mood, constant worry, or sleep trouble that makes daily life hard to cope with.
About Stay Asleep Through the Night
What this goal means
This goal is about sleep maintenance: sleeping on without repeated awakenings after you have dropped off. The NHS lists waking up several times during the night as one of the signs of insomnia, and sleep researchers call time awake after first falling asleep wake after sleep onset.
Brief awakenings are a normal part of sleep, and most are forgotten by morning. It becomes a goal worth working on when waking is frequent, long, or leaves you tired the next day.
1,2What it can feel like
Typical experiences are waking at the same time most nights, waking hot, with a full bladder, to a noise or a partner moving, with a pounding heart, or for no reason you can name. Some people fall back to sleep easily; others lie awake for a long time. That second part, what to do once you are awake, is covered on its own page.
1What can make you wake
The NHS lists noise, a room that is too hot or cold, an uncomfortable bed, alcohol, caffeine and nicotine, stress, anxiety and depression among the most common causes of insomnia. A review of studies of healthy volunteers found that alcohol, at all doses, increased sleep disruption in the second half of the sleep period. A review of 74 field studies found that road, rail and aircraft noise are linked with measured awakenings, with about 35 percent higher odds of awakening for each 10 dBA rise in the loudest indoor noise.
Heat matters too: a review of studies on the thermal environment found that heat exposure increased wakefulness during sleep when people used bedding and clothing as in real life. Needing to pass urine, hot flushes and night sweats, restless legs and breathing pauses during sleep are common medical reasons; they are listed below.
1,3,4,5,6Conditions that can be behind it
Waking often can be linked to sleep apnea (the NHS lists waking up a lot as a symptom), restless legs syndrome, night urination caused by an enlarged prostate, infection, diabetes or heart or kidney problems, night sweats around menopause, pain, anxiety or depression, and some medicines. MedlinePlus notes that waking often at night to urinate can be linked to obstructive sleep apnea and that the urination may ease when the sleep problem is under control.
Treating the underlying cause is often what makes the difference, so a pattern that keeps repeating is worth raising with a clinician.
7,8,9,6,1Realistic expectations
In a meta-analysis of 20 trials of face-to-face cognitive behavioral therapy for insomnia (CBT-I), time awake after falling asleep fell by about 26 minutes on average, with changes that seemed to be sustained later on. That is a meaningful change, not an instant cure. Habit changes usually need a couple of weeks to show.
Adults need about 7 to 9 hours of sleep. Waking briefly once or twice and drifting back is not a problem in itself; the aim is fewer and shorter awakenings, not never waking.
2,1Who this applies to
Adults who wake repeatedly in the night. If your main difficulty is lying awake at bedtime, waking much too early or feeling unrefreshed, see the linked goals. Pregnant people, older adults and people who work shifts have different patterns and needs; see the life-stage guide.

Insomnia → Sleep apnea → Restless legs syndrome → Urinary symptoms and enlarged prostate (night urination) → Hot flashes (night sweats) →
A manageable starting plan
An educational starting point, not a personal prescription. Adjust it to your own situation and any advice from your clinician.
Your first actions
- Keep a two-week sleep diary: bedtime, number of awakenings, what woke you, caffeine, alcohol, evening drinks.
- Move caffeine to the morning and keep alcohol out of the last hours before bed.
- Fix the bedroom: cooler, darker and quieter, with comfortable bedding.
- Keep a fixed wake time and avoid long naps.
Optional additions
- Spread fluids earlier in the day if you get up to urinate.
- Add daily activity, with hard exercise earlier in the day.
- Try a calming practice such as breathing or mindfulness before bed.
- Layer breathable bedding if you have night sweats.
What to track
- Number of awakenings and roughly when they happen.
- Likely triggers: noise, heat, toilet, pain, partner, dreams.
- Snoring, gasping or leg symptoms noticed by you or a partner.
- Daytime energy, and any new medicine or supplement.
When to reassess
Give the habit and environment changes about two weeks. If you still wake often on most nights, or the problem has lasted for months, take your diary to a clinician and ask about checks for sleep apnea, restless legs, night urination and CBT-I.
When to seek professional support
- See a doctor if night waking lasts for months, affects daily life, or comes with loud snoring, gasping, restless legs, frequent night urination or drenching sweats.
- Ask about CBT-I; many programs are available online as well as in person.
- For what to do when you are awake in the night, see the page on falling back asleep.
What helps
Ordered by how well the research supports each step. Evidence strength is shown on every card; precautions sit next to the advice.
Start here
Keep alcohol out of the hours before bed
Moderate certaintyAddresses: Fewer broken stretches in the second half of the night
Why it may help: A qualitative review of studies in healthy volunteers found that alcohol at all doses shortened the time to fall asleep and made the first half of sleep more consolidated, but increased sleep disruption in the second half. This is why a nightcap can feel helpful and still leave you waking at 3 or 4 am. The NHS also advises against alcohol in the last hours before bed.
How to apply it: Finish any drink well before bedtime (the NHS advises not drinking alcohol for at least 6 hours before bed in its insomnia advice), keep intake low, and notice whether nights improve after alcohol-free evenings.
Who it may suit: Anyone who wakes in the second half of the night and drinks in the evening.
Precautions: If you drink heavily, do not stop suddenly without medical advice: withdrawal can be dangerous. Alcohol also worsens snoring and sleep apnea.
3,1Move caffeine earlier in the day
Moderate certaintyAddresses: Less disturbed sleep
Why it may help: In a home study, 400 mg of caffeine taken 0, 3 or 6 hours before habitual bedtime each disturbed sleep compared with placebo, and the authors concluded that caffeine should be avoided for at least 6 hours before bed. The NHLBI notes caffeine effects can last up to 8 hours.
How to apply it: Have coffee, tea, cola and energy drinks in the morning or early afternoon, and check labels for hidden caffeine (some pain relievers, chocolate, green tea). Cut back gradually to avoid headaches.
Who it may suit: Anyone who drinks caffeine after lunch, particularly people who wake in the night.
Precautions: The trial used a high dose (400 mg) and measured sleep disturbance and total sleep time, so a small morning cup is not expected to cause the same effect. Sensitivity to caffeine varies.
10,1,11A regular wake-up time and a protected sleep window
Moderate certaintyAddresses: A steadier sleep rhythm and fewer long awakenings
Why it may help: The NHS advises getting up at the same time every day and going to bed only when sleepy; NHLBI suggests keeping weekend sleep times within about an hour of weeknights. Staying in bed much longer than you sleep is one of the things CBT-I corrects, which is part of how it reduces time awake in bed.
How to apply it: Choose a wake time you can keep seven days a week. Avoid spending extra hours in bed hoping to catch up. If you are not sleepy, wait before getting into bed.
Who it may suit: Most adults with fragmented sleep.
Precautions: Do not cut your time in bed sharply by yourself; tightening the sleep window is a CBT-I technique best guided by a trained clinician or validated program, because it can cause sleepiness at first.
1,11,2Additional options
A cool, dark, quiet bedroom, with noise handled
Moderate certaintyAddresses: Fewer awakenings caused by heat, light or sound
Why it may help: The NHS advises making the bedroom dark and quiet, using curtains, blinds, an eye mask or ear plugs if needed, and keeping the mattress, pillows and covers comfortable. A systematic review found road, rail and aircraft noise are associated with awakening in sleep studies, and a thermal-environment review found heat increased wakefulness when people slept in bedding and clothing.
How to apply it: Aim for a cool room with breathable bedding, close curtains or use an eye mask, try ear plugs or a steady background sound if noise wakes you, and check that your mattress and pillow are comfortable.
Who it may suit: People who wake because of heat, a noisy street, a partner, a pet or early light.
Precautions: Use ear plugs safely and make sure you can still hear a smoke alarm or a child. Very cold rooms can also affect the body, so aim for comfortable rather than as cold as possible.
1,4,5,11Regular daytime physical activity
Moderate certaintyAddresses: Possible reduction in time awake after falling asleep
Why it may help: A meta-analysis of 66 studies found that acute exercise had a moderate beneficial effect on wake time after sleep onset, and regular exercise had small to medium benefits on sleep. The NHS advises exercising regularly during the day but not in the 4 hours before bed.
How to apply it: Build in a daily walk or other activity you enjoy, ideally with some daylight, and keep hard exercise earlier in the day.
Who it may suit: Most adults who are able to be active.
Precautions: Check with a clinician before starting if you have a heart condition, are pregnant or have not exercised for a long time. Effects varied with age, sex, timing and type of exercise.
12,1,11Plan evening drinks if you wake to urinate
Low certaintyAddresses: Fewer trips to the bathroom at night
Why it may help: MedlinePlus lists drinking a lot of fluid in the evening, and caffeine or alcohol with or after dinner, as causes of urinating more at night. It suggests keeping a diary of what you drink and how often you urinate.
How to apply it: Spread fluids through the day, drink less in the last hours before bed, and empty your bladder before sleeping. Note how many times you get up for two weeks.
Who it may suit: Adults who get up one or more times a night to pass urine.
Precautions: Do not cut fluids dramatically, especially in hot weather, when ill or if you take water pills; ask a clinician. Persistent night urination can reflect an enlarged prostate, diabetes, infection, heart or kidney problems or sleep apnea and should be checked.
9Cool the body and manage night sweats
Low certaintyAddresses: Fewer wake-ups caused by hot flushes
Why it may help: In a sleep-lab model of induced hot flashes in 28 women, 66 percent of hot flashes occurred within 5 minutes of an awakening; the researchers concluded that hot flashes arose most commonly during wake and light sleep and typically preceded or coincided with wake episodes. The NHS notes that sleep problems may be worse if you also have night sweats.
How to apply it: Use layered, breathable bedding and nightwear, keep the room cool, keep a glass of water near the bed, and see the hot flashes page for other options. Speak with a clinician if night sweats are frequent.
Who it may suit: People in perimenopause or menopause, and anyone with drenching night sweats.
Precautions: Night sweats can have causes other than menopause, including infections, thyroid problems and some medicines; see a doctor if they are severe, new or come with weight loss or fever.
13,6Check for sleep apnea and restless legs
Moderate certaintyAddresses: Treating the cause can reduce awakenings
Why it may help: The NHS lists gasping, snorting or choking noises, loud snoring and waking up a lot as symptoms of sleep apnoea, and says it needs treatment because it can lead to more serious problems. For restless legs syndrome, symptoms are usually worse at night when resting and can affect sleep.
How to apply it: Ask a bed partner to watch for pauses in breathing, and see a GP or doctor if you recognise the signs. Home measures the NHS lists for restless legs include day-time exercise, a warm bath or heat pads before bed, and stretching or massage when symptoms start.
Who it may suit: Anyone with loud snoring, gasping, daytime sleepiness or leg discomfort at night.
Precautions: Do not take sleeping pills for sleep apnea unless a doctor recommends them: the NHS warns they can make it worse.
7,8Still being studied
CBT for insomnia (CBT-I)
High certaintyAddresses: Less time awake during the night
Why it may help: In a meta-analysis of 20 randomized trials (1,162 adults with chronic insomnia), multicomponent CBT-I shortened wake time after sleep onset by about 26 minutes (95% CI 15 to 37) and sleep efficiency rose by about 10 percentage points, with gains that seemed to be sustained later. The American College of Physicians recommends CBT-I as the initial treatment for chronic insomnia, and the AASM strongly recommends multicomponent CBT-I.
How to apply it: Delivered face to face, in a group or through a validated online program over several weeks, usually with a diary, a set sleep window, stimulus control, relaxation and work on unhelpful thoughts about sleep.
Who it may suit: Adults whose sleep problem has lasted 3 months or longer or keeps returning.
Precautions: Parts of CBT-I (such as limiting time in bed) can cause short-term sleepiness; take care when driving. The trials excluded people whose insomnia came with other sleep or medical conditions, so apnea or other causes should be checked first.
2,14,15Group CBT-I
Moderate certaintyAddresses: Fewer awakenings, with similar benefits outside one-to-one care
Why it may help: A meta-analysis of eight randomized trials found medium to large effect sizes for sleep onset latency, sleep efficiency and wake after sleep onset, and the effects remained at follow-up 3 to 12 months later.
How to apply it: Attending a clinician-led group program over several weeks and doing the between-session tasks.
Who it may suit: People who prefer group support or have limited access to one-to-one therapy.
Precautions: Same cautions as CBT-I. The meta-analysis pooled only eight trials.
16Mindfulness meditation
Low certaintyAddresses: May improve overall sleep quality
Why it may help: A randomized trial of 49 older adults with moderate sleep disturbance found that a 6-week mindfulness program (2 hours a week) improved a sleep-quality score more than a sleep-hygiene education course. The trial was small and measured overall sleep quality, not the number of awakenings.
How to apply it: Join a structured program or follow a guided practice daily; the trial included assigned homework.
Who it may suit: Adults who find calm attention practices helpful and want a non-drug option.
Precautions: Evidence is from one small trial in older adults. Mindfulness can occasionally be uncomfortable for people with trauma; go gently.
17Food & nutrition
Eating and drinking in the evening
The NHS advises not eating a big meal late at night, and the NHLBI says a light snack is fine. Heavy meals within a few hours of bed are best avoided for sleep. For people who wake to urinate, MedlinePlus lists large evening drinks as a cause.
These are habit tips from health agencies rather than proven treatments for staying asleep.
1,11,9Alcohol and caffeine, the two drinks that matter most
Caffeine taken even 6 hours before bed disturbed sleep in a home trial, and alcohol increased sleep disruption in the second half of the night in a review of volunteer studies. For many people these two changes are the first and cheapest step.
Herbal teas without caffeine, such as chamomile, are a gentle evening alternative. Sip them earlier in the evening if you wake to urinate.
10,3,1Foods and supplements studied for sleep
No food has good evidence for preventing night waking. Small studies of foods such as kiwifruit and tart cherry looked at falling asleep or sleep time rather than awakenings, so they are covered on the page about falling asleep faster rather than here.
1Remedies & supplements
Traditional use, laboratory findings and human trials are kept apart. "Natural" does not mean safe.
Magnesium
Very low certaintyStudied form and route: Oral supplement or magnesium-rich foods
Intended outcome: Not shown to reduce night waking
Human evidence: A meta-analysis of three randomized trials (151 older adults) found sleep onset about 17 minutes shorter than placebo; total sleep time improved by about 16 minutes but not significantly. The authors rated the evidence as low to very low quality, with moderate-to-high risk of bias.
Limits: Small trials, older adults only, not designed to measure awakenings. Products and doses vary.
Interactions and precautions: Can cause diarrhea; avoid or use only with advice in kidney disease. Check with a pharmacist about interactions, and ask before use in pregnancy, breastfeeding or older age.
18Melatonin
Not enough evidenceStudied form and route: Short-term oral supplement
Intended outcome: Mainly studied for falling asleep, not for staying asleep
Human evidence: Melatonin has been studied mostly for shortening sleep onset and for body-clock problems. The evidence for fewer awakenings is limited, so it is covered on the melatonin page rather than claimed here.
Limits: Effects are modest; products vary in strength and quality; long-term safety is not established.
Interactions and precautions: Can cause drowsiness and may interact with medicines. Ask a pharmacist or doctor first, and do not use in pregnancy, breastfeeding or children without advice.
1Herbal sleep products (valerian, chamomile, lavender)
Not enough evidenceStudied form and route: Teas, capsules, pharmacy sleep products
Intended outcome: Short-term comfort at best; not shown to prevent waking
Human evidence: The NHS says pharmacy sleep products containing valerian or lavender cannot cure insomnia, may help for 1 to 2 weeks and should not be taken for longer.
Traditional use: Valerian, chamomile and lavender have long traditional use as calming evening herbs.
Limits: Product strength varies, and these products have not been shown to reduce awakenings.
Interactions and precautions: Valerian and other sedating herbs can cause drowsiness and interact with medicines, including sedatives and alcohol. Avoid in pregnancy and breastfeeding unless advised, and check with a pharmacist first.
1Therapies & care
Established professional care for repeated night waking starts with finding the cause (for example sleep apnea, restless legs, night urination or menopausal symptoms) and, for persistent insomnia, with cognitive behavioral therapy for insomnia (CBT-I). This page does not recommend medicines or doses, and you should not stop a prescribed medicine on your own.
CBT for insomnia (CBT-I)
High certaintyPsychological and behavioral therapy A structured program of stimulus control, a set sleep window, relaxation and changing unhelpful thoughts about sleep. In a meta-analysis of 20 trials it cut time awake after falling asleep by about 26 minutes, and the ACP and AASM recommend it as first-line care.
Who it may suit: Adults with insomnia lasting 3 months or longer, or shorter problems that keep returning.
Precautions: Short-term sleepiness is possible. Work with a trained clinician or validated program, and have sleep apnea and other causes checked first.
2,14,15Assessment for sleep apnea
Moderate certaintyMedical assessment The NHS describes testing by a sleep clinic, often with devices you wear overnight, and treatments that range from lifestyle changes to a CPAP machine, which it says can improve sleep quality and reduce related risks.
Who it may suit: People with loud snoring, gasping or choking at night, or marked daytime tiredness.
Precautions: Sleeping pills can make sleep apnea worse, so tell the clinician about everything you take.
7Assessment of night urination
Moderate certaintyMedical assessment MedlinePlus advises seeing a provider if waking to urinate continues over several days, bothers you, or comes with burning, pain or blood in the urine. Causes include infection, enlarged prostate, diabetes, kidney or heart conditions and some medicines.
Who it may suit: Anyone who gets up to urinate more than usual.
Precautions: Do not restrict fluids heavily without advice.
9Support for menopausal symptoms
Moderate certaintyMedical advice The NHS suggests contacting a GP if you think you have menopause or perimenopause symptoms and want to know your options; early advice can reduce the effects on health and daily life.
Who it may suit: People with night sweats or hot flushes that wake them.
Precautions: Night sweats can have other causes; have new, severe or unexplained ones checked.
6What to avoid
Habits, products and claims that can get in the way. Never stop a prescribed medicine without talking to the professional who prescribed it.
Risks that apply to most people
Alcohol as a sleep aid
Moderate certaintyWhy: Alcohol can shorten the time to fall asleep, but a review found it increased sleep disruption in the second half of the night, and reduced REM sleep at moderate and high doses. This is a common reason for waking at 3 am.
Who it applies to: Anyone who wakes after a drink, particularly in the second half of the night. Risks are higher with sleep apnea or sedating medicines.
Try instead: Keep drinks well before bed or skip them on nights you want unbroken sleep; use a calming routine instead.
3,1Caffeine in the afternoon and evening
Moderate certaintyWhy: A home trial found 400 mg of caffeine taken 6 hours before bed still disturbed sleep; the NHLBI says its effects can last up to 8 hours.
Who it applies to: Coffee, tea, cola, energy drinks and some medicines or supplements containing caffeine.
Try instead: Keep caffeine to the morning and early afternoon.
10,11Nicotine near bedtime
Low certaintyWhy: The NHS advises against smoking in the hours before bed and lists nicotine among the common causes of insomnia; the NHLBI notes nicotine is a stimulant.
Who it applies to: Smokers and users of nicotine products.
Try instead: Avoid nicotine in the evening and ask a pharmacist or clinician about stopping support.
1,11A big meal or hard exercise late at night
Low certaintyWhy: The NHS advises against a big meal late at night and against exercise in the last 4 hours before bed; the NHLBI says a light snack is fine.
Who it applies to: Late dinners and evening workouts.
Try instead: Eat the main meal earlier and keep strong workouts for morning or afternoon.
1,11Personal triggers to check
Noise and light in the bedroom
Moderate certaintyWhy: A systematic review linked road, rail and aircraft noise with measured awakenings, with about 35 percent higher odds of awakening for every 10 dBA rise in indoor peak noise. The NHS lists noise as a common cause of insomnia and advises a dark, quiet room.
Who it applies to: Light sleepers, people near roads, airports or railways, and people sharing a room.
Try instead: Use curtains or an eye mask, ear plugs or steady background sound, and move devices that glow or buzz out of the room.
4,1A bedroom that is too hot or too cold
Moderate certaintyWhy: A review of thermal-environment studies found heat exposure increased wakefulness during sleep and decreased deep and REM sleep when people slept in bedding and clothing. The NHS lists a room that is too hot or cold among the common causes of insomnia.
Who it applies to: Warm climates, heavy bedding, electric blankets left on, and people with night sweats.
Try instead: Use breathable layers you can remove, a fan or open window if safe, and warm bedding in cold weather.
5,1Large drinks late in the evening
Low certaintyWhy: MedlinePlus lists drinking too much fluid in the evening, or caffeine and alcohol with or after dinner, as causes of waking to urinate at night.
Who it applies to: People who get up to urinate at night.
Try instead: Move most drinks earlier in the day and keep a diary of fluids and trips to the bathroom.
9Medicines that can disturb sleep
Low certaintyWhy: The NHS notes that many medicines can cause insomnia, and MedlinePlus lists water pills (diuretics) among causes of urinating more at night.
Who it applies to: Anyone who takes regular medicines and notices new night waking.
Try instead: Ask your prescriber or pharmacist whether timing or choice of a medicine could play a part. Do not change or stop a medicine on your own.
1,9Products that need caution
Over-the-counter sleep aids taken night after night
Moderate certaintyWhy: The NHS says pharmacy sleep products, which may contain valerian, lavender or an antihistamine, cannot cure insomnia, may help for 1 to 2 weeks and should not be taken for longer; some cause drowsiness.
Who it applies to: Anyone using sleep products nightly, especially older adults and people who drive.
Try instead: Use them short term only, check interactions with a pharmacist, and look at CBT-I for lasting change.
1Sleep supplements and natural aids → Medicine interactions →
Sleeping pills when sleep apnea is possible
Moderate certaintyWhy: The NHS says not to take sleeping pills for sleep apnoea unless a doctor recommends them, because they can make it worse.
Who it applies to: People who snore loudly, gasp or choke at night, or are sleepy in the day.
Try instead: Get the breathing problem checked first.
7Unsupported claims
"A nightcap helps you sleep through"
Moderate certaintyWhy: Alcohol may help you drop off, but the evidence review found more sleep disruption in the second half of the night and less REM sleep at higher doses.
Who it applies to: Social media, hospitality and habit.
Try instead: Treat alcohol as something that can break sleep, not protect it.
3"Everyone must sleep 8 hours without waking"
Moderate certaintyWhy: The NHS says adults need 7 to 9 hours on average and that needs differ. Brief awakenings are part of normal sleep; the concern is frequent or long wake-ups and daytime effects.
Who it applies to: Sleep trackers and wellness posts.
Try instead: Judge sleep by how you feel in the day and how often you are awake for long periods.
1"A supplement will keep you asleep all night"
Low certaintyWhy: No supplement tested in the studies read for this page has strong evidence for fewer awakenings. Magnesium, the best known, was studied in only three small older-adult trials with a moderate-to-high risk of bias, and measured falling asleep and total sleep time, not awakenings.
Who it applies to: Product labels and online reviews.
Try instead: Treat supplements as an optional extra and fix alcohol, caffeine, environment and medical causes first.
18Common mistakes
Staying in bed for hours to make up for a broken night
Moderate certaintyWhy: Extra time in bed gives more opportunity to be awake. The NHS advises sticking to your regular hours rather than sleeping in after a bad night.
Who it applies to: Anyone recovering from bad sleep.
Try instead: Keep a fixed wake time and avoid long naps; if you must nap, keep it short and early.
1,11Assuming it is just age or stress without checking
Moderate certaintyWhy: Waking can be a symptom of sleep apnea, restless legs, night urination or hot flushes, all of which respond to treatment.
Who it applies to: Anyone whose night waking keeps happening.
Try instead: Use the two-week diary and raise patterns with a clinician.
7,8,9,6Evidence & safety
What the research shows
The strongest evidence is for cognitive behavioral therapy for insomnia, which reduced time awake after first falling asleep by about 26 minutes in a meta-analysis and is the first-line treatment recommended by major guidelines. Alcohol, caffeine, noise and heat have supportive evidence for disrupting sleep, and health agencies advise a cool, dark, quiet room. For supplements and herbs the evidence for staying asleep is weak or absent.
Limits of the evidence
- Many studies of alcohol, heat and caffeine were small, short or in healthy volunteers.
- The noise review combined studies with different measures and the sleep-disturbance surveys depended on how the question was worded.
- The hot-flash sleep study used an induced-menopause model in 28 women.
- The magnesium trials were small, in older adults, and at moderate-to-high risk of bias.
- Wake time is often self-reported, which can be inaccurate.
Precautions and interactions
- Check supplements and herbs with a pharmacist if you take any medicine.
- Sedating products and alcohol together raise the risk of accidents and breathing problems.
- Do not drive when sleepy.
- Never stop a prescribed medicine because of sleep problems without speaking to your prescriber.
Life-stage considerations
- Pregnancy and breastfeeding: night waking is common, including for bladder and discomfort reasons; avoid herbal sleep products and melatonin unless a clinician advises.
- Children and teenagers: sleep needs and causes of waking differ; do not give melatonin or herbs without a pediatrician's advice.
- Older adults: night urination, medicines and sleep apnea are more common, and falls at night are a risk; review medicines and sleep aids with a clinician.
- Menopause: night sweats are a frequent cause; see the hot flashes page.
Warning signs
- Loud snoring, gasping, choking or breathing pauses at night.
- Waking in distress, short of breath, or with chest pain: seek urgent medical care.
- Painful or bloody urination, or great thirst with frequent urination.
- Persistent low mood, hopelessness or thoughts of self-harm: seek help from a doctor or local emergency services.
- Nearly falling asleep while driving.
Claim checks
A glass of wine helps you sleep through the night
Moderate certaintyIt may help you fall asleep, but a review found more sleep disruption in the second half of the night at all doses.
3Caffeine in the afternoon does not matter if you can fall asleep
Moderate certaintyA home trial found 400 mg of caffeine taken 6 hours before bed still disturbed sleep, even if falling asleep was possible.
10CBT-I only helps people who cannot fall asleep
High certaintyA meta-analysis found it shortened time awake after sleep onset by about 26 minutes as well as time to fall asleep by about 19 minutes.
2Magnesium keeps you asleep until morning
Very low certaintyThe small trials pooled in a meta-analysis found a shorter time to fall asleep and a non-significant gain in total sleep time, with low to very low quality evidence.
18Questions people ask
Is it normal to wake up during the night?
Yes. Brief awakenings are part of normal sleep and often go unremembered. The NHS lists waking up several times during the night as a symptom of insomnia when it happens regularly and affects how you feel in the day.
Why do I wake up at the same time every night?
There is no single answer. Alcohol earlier in the evening, a full bladder, heat, noise, night sweats, breathing pauses or stress can all play a part. A two-week diary of when and what wakes you is the best way to spot a pattern.
Does alcohol help me sleep through the night?
It may help you fall asleep, but a review of volunteer studies found that alcohol increased sleep disruption in the second half of the night at all doses.
How many hours before bed should I stop caffeine?
A home trial found that caffeine taken 6 hours before bedtime still disturbed sleep, and the NHS advises avoiding caffeine for at least 6 hours before bed. The NHLBI says its effects can last up to 8 hours.
Why do I wake to go to the toilet?
MedlinePlus lists large evening drinks, caffeine or alcohol, infection, an enlarged prostate, diabetes, pregnancy, some medicines and sleep apnea among the causes. If it continues over several days or bothers you, see a provider.
Could sleep apnea be waking me up?
It can be. The NHS lists breathing stopping and starting, gasping or snorting noises, waking up a lot and loud snoring as symptoms. Ask a partner to watch, and see a doctor if you recognise these signs.
Can night sweats wake me up?
Yes. The NHS says sleep problems may be worse with night sweats in menopause, and in a lab model most induced hot flashes occurred just before or during awakenings. See the hot flashes page for more.
Does a cooler bedroom help?
A review of thermal-environment studies found that heat exposure increased wakefulness, and the NHS lists a room that is too hot or cold among common causes of insomnia. Aim for comfortable, cool and well ventilated.
Do magnesium or melatonin help me stay asleep?
The research mainly looked at falling asleep. A meta-analysis of magnesium found a shorter time to fall asleep but rated the evidence low to very low, and melatonin is mostly studied for sleep onset and body-clock issues.
What helps most if it keeps happening?
For persistent insomnia, CBT-I has the strongest evidence: a meta-analysis found about 26 fewer minutes awake after falling asleep. It also helps to have sleep apnea, restless legs, night urination and menopausal symptoms checked.
When should I see a doctor?
See a doctor if waking has gone on for months, affects your daily life, or comes with loud snoring, gasping, restless legs, frequent night urination or drenching sweats.
