Perimenopause Insomnia: Why You're Waking at 3am (And What Can Help)
Waking Up at 3am During Perimenopause?
You used to sleep reasonably well.
Perhaps you occasionally had a bad night, but nothing particularly concerning.
Then, somewhere in your forties, things started changing.
You fall asleep without too much difficulty, but at 3am you're awake.
Sometimes you're hot.
Sometimes your heart is racing.
Sometimes you're just lying there, completely alert, wondering why on earth you're awake again.
And the next day? You're exhausted.
Naturally, you start looking for answers.
Is it perimenopause? Is it stress? Is it insomnia? Or is this just what happens to sleep in midlife?
The answer is that it could be several things. And understanding what's actually waking you is far more useful than automatically assuming it's all down to hormones.
Why does sleep change during perimenopause?
Let's start with the hormones, because they absolutely can play a part.
During perimenopause, levels of oestrogen and progesterone fluctuate. These changes can affect sleep directly and indirectly.
Night sweats, changes in temperature regulation, mood changes and increased anxiety can all contribute to disrupted sleep.
But here's something important.
Not every woman who wakes during perimenopause is waking because of a hot flush.
And not every woman who wakes at 3am has a hormonal sleep problem.
There can be several things happening at once.
The first question I'd ask is: what's actually waking you?
When somebody tells me they're waking at 3am, I'm interested in what happens immediately before and after they wake.
Because there is a difference between being woken by something and waking naturally, then struggling to get back to sleep.
For example:
You wake feeling hot and uncomfortable.
Night sweats or temperature changes may be contributing to the awakening. Managing those symptoms could make a meaningful difference.
You wake needing the toilet.
Bladder symptoms can become more common during perimenopause. But it's also worth exploring whether the need to go to the toilet woke you, or whether you noticed it after waking for another reason.
You wake with your mind racing.
Perhaps you're thinking about work, your children, your parents or something that happened yesterday.
In this situation, the problem may not simply be what woke you. It may be what's keeping you awake afterwards.
You wake feeling completely alert for no obvious reason.
This is where I'd want to understand your overall sleep pattern, including your body clock, sleep pressure and whether you've started spending longer in bed trying to compensate for poor sleep.
These are very different situations.
And they don't necessarily need the same solution.
Why 3am?
There's nothing magical about 3am.
We move through different stages of sleep throughout the night, and brief awakenings are a normal part of that process.
As the night progresses, the balance of sleep stages changes, and the amount of sleep pressure we've built up during the day gradually reduces.
That means returning to sleep after an awakening can sometimes feel more difficult in the second half of the night.
Now add a hot flush, an uncomfortable bedroom, stress or worries about tomorrow.
Suddenly, a perfectly ordinary awakening can become a much longer period of wakefulness.
If this starts happening regularly, you may begin anticipating it.
You go to bed wondering whether tonight will be another bad night.
You wake and immediately check the time.
You calculate how many hours you've got left before the alarm.
And before you know it, you're no longer simply awake.
You're worrying about being awake.
Midlife is often a particularly busy time for the brain
Something else I think deserves more attention is what women's lives actually look like during this stage.
You might be managing a demanding career, supporting teenagers, caring for ageing parents, navigating relationships or dealing with significant changes in your own life.
Sometimes all of those things at once.
Yet, when sleep becomes difficult, the conversation can quickly become entirely about hormones.
Hormones matter enormously.
But so does everything else.
A brain that's been processing information, solving problems and responding to other people's needs all day doesn't necessarily stop doing those things because you've climbed into bed.
And when you wake during the night, those unfinished thoughts can become very noticeable.
This doesn't mean stress is always the cause of the awakening.
It means that what happens during the day may influence what happens after you wake.
What actually helps with perimenopause insomnia?
The starting point is understanding what's contributing to your particular sleep difficulty.
1. Identify what is disrupting your sleep
If you're regularly waking hot, sweating or experiencing other menopausal symptoms, speak to your GP about treatment options.
Hormone replacement therapy (HRT) and other treatments may help, depending on your symptoms and medical circumstances.
You don't have to simply put up with disrupted sleep because you're approaching menopause.
2. Look at what happens after you wake
If you're awake and immediately start worrying about tomorrow, your attention can become focused on the fact that you're not sleeping.
This can increase frustration and alertness.
Rather than making getting back to sleep your immediate task, consider whether you can reduce the pressure you're putting on yourself.
You don't have to solve your sleep problem at 3am.
3. Consider your sleep pattern across the whole day
Sleep doesn't begin at bedtime.
Your sleep pressure builds while you're awake, and your body clock helps regulate when you feel sleepy and alert.
If you've started going to bed much earlier, lying in longer or spending additional time in bed to make up for disrupted sleep, it's worth looking at whether those changes are helping.
Sometimes they can unintentionally contribute to ongoing insomnia.
That doesn't mean you should force yourself to stay awake when you're exhausted. It means your sleep schedule needs to be considered as part of the bigger picture.
4. Don't overlook treatable sleep conditions
Not every sleep problem in midlife is caused by perimenopause.
Sleep apnoea, restless legs syndrome, chronic insomnia and other medical conditions can affect sleep.
If you're snoring heavily, waking gasping, experiencing uncomfortable leg sensations or feeling excessively sleepy during the day, it's important to seek medical advice.
5. Remember that insomnia has effective treatments
If difficulty sleeping has become an ongoing pattern, cognitive behavioural therapy for insomnia (CBT-I) is an evidence-based treatment.
It works with the processes that regulate sleep and addresses the thoughts and behaviours that can maintain insomnia.
NICE also recommends considering menopause-specific CBT for sleep problems associated with hot flushes and night sweats.
The important thing is matching the support to what's actually happening.
You don't have to choose between hormones and sleep science
One of the things I find frustrating about conversations around midlife sleep is the tendency to look for one explanation.
It's hormones.
It's cortisol.
It's stress.
It's your bedtime routine.
Honestly sleep is rarely that straightforward.
Hormonal changes can contribute to disrupted sleep. So can life circumstances, underlying health conditions and changes in the way you respond to being awake.
And sometimes several of those factors are interacting.
The question isn't simply, "How do I stop waking at 3am?"
It's, "What's contributing to my waking, and what's making it difficult to return to sleep?"
Because once you understand that, you can start making changes that are relevant to you.
Not somebody else's bedtime routine.
Not another list of things you're apparently doing wrong.
Your sleep. Your circumstances. Your starting point.
Need help understanding your sleep?
I'm Kerry Davies, founder of The Sleep Fixer, and I've worked in sleep for over 15 years.
In my £97 Personal Sleep Strategy Session, we explore what's actually happening with your sleep, what might be contributing to your difficulties and, most importantly, what you can do about it.
I use evidence-based techniques from Cognitive Behavioural Therapy for Insomnia (CBT-I), tailored to your individual sleep difficulties.
It's not a full CBT-I programme, but it gives you a clearer understanding of your sleep and practical strategies you can start using.
For those who need more comprehensive support, I also offer a full CBT-I programme, working through the different components of this evidence-based treatment for insomnia.
The aim isn't to give you another endless list of sleep rules. It's to understand what's happening with your sleep and find an approach that works for you.
Fancy experimenting with your sleep?
I'm also going to be sharing some Sleep Fixer Experiments over on my social media.
Simple, practical experiments to help you understand your sleep, challenge some of the advice we're constantly given and discover what actually makes a difference for you.
Because sometimes the best way to understand your sleep is to get curious about it, rather than trying to perfect it.
