To stay asleep all night, get up at the same time every day, get daylight in the morning, stop caffeine 6 hours before bed, go easy on alcohol, and keep your bedroom cool, dark and quiet. If you wake, don’t check the clock. Still awake after about 20 minutes? Get up until you feel sleepy.
Below: why you wake and the fix for each cause, what to do in the moment, what to change by day and evening, CBT-I, a two-week plan and when to see a GP.
The goal isn’t zero wakings. Everyone surfaces briefly between sleep cycles. Sleeping through the night really means waking without noticing, or drifting straight back off. That’s what this plan trains.
Is it normal to wake in the night?
Yes. You cycle through lighter sleep, deep sleep and dreaming (REM) sleep several times a night, and the first REM period starts about 90 minutes after you fall asleep. Between cycles you come close to the surface, and most of these brief wakings are forgotten by morning.
The night isn’t even, either. Deep sleep comes in longer stretches in the first half of the night, while REM periods get longer towards morning. That’s why the second half of the night is lighter and the early hours are when most people wake, and stay awake.
It becomes a problem when you can’t get back to sleep, when it happens most nights, or when you feel tired, irritable or foggy the next day. If that sounds like you, the steps below help. If you mainly struggle to drop off in the first place, start with why can’t I sleep? instead.
Why you wake: clue and fix
Most people have one or two clear triggers. Find yours and fix that first. For the early-hours pattern in depth, see why do I wake up at 3am?
| Why you wake | Clue | Fix |
|---|---|---|
| Normal cycle changes | Brief, you drift off again, fine the next day | Nothing. Don’t check the time |
| Stress and a busy mind | You wake with a jolt and your mind goes straight to worries | An evening worry list, slow breathing, CBT-I if it lasts. See anxiety at night |
| Alcohol | You drop off fast, then wake hot, thirsty or restless in the small hours | Alcohol-free nights and an earlier last drink. See alcohol and sleep |
| Caffeine | Tea, coffee, cola or energy drinks after lunch | Nothing caffeinated within 6 hours of bed |
| Needing the loo | You wake to pee once or more a night | Drink more earlier in the day, less late on. See waking up to pee at night |
| Too hot or too cold | Covers off, then on again; sweaty or cold feet | A cooler room and layered bedding. See best temperature for sleep |
| Noise and light | Birds, traffic, the heating, early light round the blinds | Earplugs, blackout blinds or a sleep mask |
| Your partner | Snoring, fidgeting, different hours | Earplugs, separate duvets. See light sleeper |
| Reflux | Burning, coughing or a sour taste lying down | Eat earlier and lighter. See acid reflux at night |
| Pain | Aching hips, back or joints wake you when you turn | Check your pillows and mattress; ask a GP or pharmacist about managing the pain |
| Hormones | Night sweats, hot flushes, waking around your period | A cool room and light layers; talk to your GP. See perimenopause and sleep |
| Sleep apnoea | Loud snoring, gasping or choking, breathing that stops and starts, very tired in the day | See a GP. See sleep apnoea |
What to do when you wake in the night
The first few minutes decide whether it’s a 2-minute waking or a 2-hour one. Stay calm and keep your brain in night mode.
- Don’t check the clock. Working out how many hours are left switches your brain on. The NHS suggests keeping clocks out of view, and that includes your phone.
- Keep the lights low. If you need the loo, use a dim night light rather than the main light, and don’t look at a screen on the way.
- Breathe slowly. Breathe in through your nose for a count of 4 and out for a count of 6 to 8, or try a body scan from your toes upwards. You’re not trying to force sleep, just to let your body settle.
- Park the thoughts. Keep a notepad by the bed. If a worry or a to-do item loops, write it down in one line and leave it for the morning.
- Get up after about 20 minutes. The NHS advice is that if you’re still awake after around 20 minutes, get up and sit somewhere comfortable, then go back to bed when you feel sleepy. Guess the time rather than checking, and read something calm in dim light.
The 20-minute rule feels backwards, but it stops your bed becoming a place where you lie awake and worry.
What to change by day and evening
Staying asleep is mostly decided before bed. These habits build a stronger drive to sleep and a steadier body clock.
By day
- Fix your wake time. Get up at the same time every day, weekends included. After a bad night, don’t sleep in: the NHS advises sticking to your regular hours, which keeps tomorrow night on track. Our sleep schedule reset walks you through it.
- Get daylight in the morning. Light reaching your eyes helps set your body clock. A walk outside soon after you get up works well, even on a grey day.
- Set a caffeine cut-off. In one study, a strong dose of caffeine taken 6 hours before bed still disturbed sleep and cut total sleep time. Count tea, coffee, cola, energy drinks and chocolate.
In the evening
- Go easy on alcohol. A review of all known studies found that alcohol helps you fall asleep faster but increases sleep disruption in the second half of the night. The NHS suggests avoiding alcohol for 1 to 2 hours before bed; earlier and less is better.
- Eat earlier and ease off drinks late on. A large, late meal makes reflux more likely, and a lot to drink before bed means trips to the loo.
- Wind down for 30 to 60 minutes. Dim the lights, stop work and screens, and do something calm: a bath, a book or slow breathing.
- Make the bedroom work. Cool, dark and quiet, used for sleep (and sex) only. Go to bed when you’re sleepy, not just because it’s a certain time.
If a warm drink is part of your wind-down, our Magnesium Glycinate Sleep Complex is a berry-flavoured evening drink with magnesium bisglycinate and citrate, glycine, L-theanine and chamomile. Magnesium contributes to a reduction of tiredness and fatigue and to normal functioning of the nervous system. It won’t stop you waking on its own: the habits above do the heavy lifting.
CBT-I: the first-line treatment for long-term insomnia
If the habits haven’t worked, the answer usually isn’t a pill. NICE guidance says cognitive behavioural therapy for insomnia (CBT-I) should be offered as the first-line treatment for long-term insomnia in adults of any age, and that sleeping tablets should be avoided for long-term use. Unlike medication, the benefits of CBT-I last after the course ends.
CBT-I combines a few proven parts:
- Stimulus control: bed is for sleep, and you get up if you’re lying awake (the 20-minute rule above).
- Sleep restriction: a shorter “sleep window” for a while to build sleep pressure, widened as sleep improves. Do this with guidance, especially if you drive.
- Cognitive therapy: loosening the worries about sleep that keep you alert at 3am.
- Relaxation and sleep hygiene to support the rest.
It helps with staying asleep in particular. A review of 20 trials with 1,162 adults with chronic insomnia found CBT-I cut time awake in the night by about 26 minutes and time taken to fall asleep by about 19 minutes, with the gains sustained afterwards. Ask your GP: it may be offered face-to-face or as an online self-help programme recommended by NICE. Our insomnia guide covers the condition in full.
A two-week plan to sleep through the night
Change a few things at a time. Keep a simple sleep diary from day 1: bedtime, rough wakings, wake time and how you felt.
| Days | What to do |
|---|---|
| 1 to 3 | Pick a fixed wake time for all 7 days. Start the diary. Use the table above to spot your likely cause. |
| 4 to 7 | Caffeine cut-off 6 hours before bed. At least 4 alcohol-free nights. Daylight within an hour of waking. Fix the bedroom: cooler, darker, quieter. |
| 8 to 10 | Add a 30 to 60 minute wind-down with dim lights and no screens. Write a worry list in the early evening. Eat earlier and ease off drinks late on. |
| 11 to 14 | Practise the night routine every time you wake: no clock, slow breathing, out of bed after about 20 minutes. Keep the wake time fixed, even after a bad night. |
| Day 15 | Review the diary. Fewer or shorter wakings? Keep going. No change, or signs of a health cause? Book a GP appointment and take the diary. |
The first week may feel harder if you’ve been sleeping in to catch up. That short-term tiredness builds the sleep pressure that carries you through the night.
When to see a GP
See a GP if:
- changing your sleep habits hasn’t helped, or you’ve had trouble sleeping for months (insomnia lasting 3 months or more is classed as long-term)
- night waking is affecting your work, mood, driving or relationships
- you snore loudly, gasp or choke in your sleep, or someone has seen your breathing stop and start
- you’re waking to pee more and more, or have new night sweats, pain or a racing heart
- you’re low or anxious, or a medicine may be keeping you awake
Your GP can check for health causes and refer you for CBT-I. GPs now rarely prescribe sleeping pills, and only for a few days or weeks at most.
FAQs
Is it normal to wake up during the night?
Yes. Everyone surfaces briefly between sleep cycles, and sleep is lighter in the second half of the night. Most brief wakings are forgotten. It’s only a problem if you can’t get back to sleep or feel tired the next day.
How can I stay asleep all night naturally?
Keep the same wake time every day, get morning daylight, stop caffeine 6 hours before bed, go easy on alcohol, wind down for 30 to 60 minutes and keep your bedroom cool, dark and quiet. If it lasts months, CBT-I is the first-line treatment.
Why can’t I stay asleep for more than 4 hours?
Common reasons are alcohol, stress, late caffeine, needing the loo, a hot bedroom, hormones or sleep apnoea, plus sleep naturally gets lighter towards morning. If it happens most nights for 3 months or more, it may be long-term insomnia, which CBT-I treats well.
Should I get up if I can’t get back to sleep?
Yes. The NHS suggests that if you’re still awake after around 20 minutes, get up and sit somewhere comfortable, then go back to bed when you feel sleepy. Keep the lights low and avoid screens while you’re up.
Do supplements help you stay asleep?
No supplement is a proven fix for night waking, and NICE recommends CBT-I rather than tablets for long-term insomnia. Magnesium contributes to normal functioning of the nervous system, so a magnesium drink can be part of a wind-down, but habits matter most.
