You fell asleep easily enough. Then, at 3am, your eyes snap open. You're hot, wide awake, and within seconds your mind is off: tomorrow's meeting, something you said last week, a bill you forgot to pay. You lie there, watching the minutes tick by, getting crosser with yourself for not being asleep.
Waking in the small hours is one of the most common sleep complaints in perimenopause and menopause. It isn't a sign that something is badly wrong with you. There are clear reasons it happens, and there's plenty you can do to make those wake-ups shorter and easier.
Why do I keep waking at 3am?
Some of the reasons have nothing to do with menopause. They're simply how sleep works. Menopause then adds a few extra nudges.
Your sleep gets lighter as the night goes on
Through the night, you cycle through the different stages of sleep several times. Each cycle lasts about 90 minutes. As the night goes on, the cycles change: you spend longer in dreaming (REM) sleep and less time in deep sleep (StatPearls: Physiology, Sleep Stages).
So the early hours are mostly lighter sleep. That makes it much easier for a noise, a full bladder or a hot flush to wake you, compared with the deep sleep of the first few hours.
Your body is starting to gear up for the day
Cortisol is often called the stress hormone, but it also helps wake you up each morning. Levels are low at the start of the night, then rise towards the end of your sleep, peaking around the time you wake up (Mohd Azmi and others, 2021).
By the small hours, your body is heading towards that rise. Your body is slowly preparing for the day. If something wakes you then, you may find yourself more alert and harder to settle than you would be at midnight.
You've also already had several hours of sleep. The heavy tiredness that carried you off at bedtime has partly worn off, so there's less pulling you back under.
Why does menopause make night waking worse?
A review of the research found that the menopause transition comes with an increase in insomnia symptoms. Difficulty staying asleep is the one that rises most. Hot flushes and night sweats are a key part of that (Baker and others, 2018).
Common culprits include:
- Night sweats. A flush can wake you suddenly, hot and with your heart racing.
- Anxiety. Perimenopause can bring anxiety that seems to come from nowhere, and it often feels worst at night.
- Needing the loo. This becomes more common around menopause.
- Worrying about sleep itself. After a run of bad nights, your brain can start to expect to wake up, which makes waking more likely.
Why does my mind race when I wake in the night?
At 3am, problems feel bigger than they really are. You're tired, it's dark and quiet, and there's nothing to distract you. Your brain does what brains do and looks for things to worry about.
Women's Health Concern, the patient arm of the British Menopause Society, points out that feeling anxious about missed sleep makes it harder to get back to sleep. It's easier to deal with worries in the daytime, when you can think clearly. So the aim at 3am isn't to solve anything. It's to put things down until morning.
How to get back to sleep at 3am
Try these steps the next time you wake:
- Don't check the clock. Knowing the time only starts the maths of how many hours are left.
- Cool down if you're hot. Throw off a layer, turn your pillow to the cool side, or have a sip of cold water.
- Slow your breathing. Breathe gently from your stomach, letting each breath out be a little longer than the breath in.
- Park your worries. Keep a notepad by the bed. Jot down anything on your mind, then say to yourself, "I'll deal with this tomorrow when I can think clearly."
- Answer the catastrophe thoughts. Swap "I'll be useless tomorrow" for "I've managed on less sleep before."
- Don't fight it. If you've been lying awake for what feels like a long time and you're getting frustrated, get up. Do something calm and dull in dim light, then go back to bed when you feel sleepy.
- Leave your phone alone. The bright screen and the endless scroll will wake you up even more.
And whatever kind of night you've had, get up at your normal time. Women's Health Concern also suggests carrying on with your plans the next day, rather than cancelling them, because that keeps worry about sleep from growing.
Daytime habits that help the night
What you do in the day has a big effect on the night. The NHS insomnia advice includes:
| Do | Avoid |
|---|---|
| Wake up and get out of bed at the same time every day | Caffeine and alcohol in the 6 hours before bed |
| Relax for at least an hour before bed | A big meal late at night |
| Keep your bedroom dark and quiet | Exercise in the 4 hours before bed |
| Only go to bed when you feel sleepy | Daytime naps |
Women's Health Concern adds that a cool bedroom helps sleep, especially if you're having night sweats. It also notes that caffeine and alcohol both affect how well you sleep, not just how quickly you drop off.
Treatments to talk to your GP about
If night waking has become a pattern, it's worth talking to your GP.
- Menopause-specific CBT. In 2024, NICE's menopause guideline (NG23) added this as an option for sleep problems, such as night-time waking, that are linked to hot flushes and night sweats.
- CBT for insomnia. The NHS says a GP may offer this face to face or through an online programme.
- HRT. NICE says doctors should offer HRT for hot flushes and night sweats. Treating those may help your sleep too.
When to see your GP
The NHS suggests seeing a GP if changing your sleep habits hasn't helped, if you've had trouble sleeping for months, or if poor sleep is making it hard to cope day to day.
Please also see your GP if you're waking drenched in sweat along with a high temperature or weight loss you can't explain, or if you're feeling low or hopeless. If you take any medicines, don't stop or change them without talking to your GP or pharmacist first.
Where relaxation and hypnosis recordings fit in
Some women like to keep a short relaxation or hypnosis recording ready on their phone for night waking. It gives a busy mind something gentle to follow, instead of the to-do list.
Our recording Back to Sleep is short and very easy to follow, because at 3am nobody wants to concentrate. It's a gentle relaxation with soft cooling imagery, designed to help you let go and drift back off. It's a relaxation recording, not a medical treatment, and it doesn't replace advice from your GP.
If you'd like to try our style first, our free Ten-Minute Calm Reset is a good place to start.
