Perimenopause and sleep: what changes, and what can help
Perimenopause can change your sleep because oestrogen and progesterone start to fluctuate, and that can bring lighter, more broken nights, night sweats and more trips to the loo. Sleep also naturally gets lighter in the second half of the night, so anything that nudges you, from a hot flush to a busy mind, is more likely to wake you fully.
If your nights feel different lately, you're in good company. Around 40 to 60% of women have disturbed sleep during perimenopause and after menopause (Sleep Health Foundation).
This guide covers what perimenopause is, the symptoms to know, why your sleep feels different, the evening habits that can help, and when it's time to talk to your GP.
What is perimenopause, and when does it start?
Perimenopause is the time leading up to, and just after, your final period. There's no set starting point: the timing is different for every woman (health.gov.au).
On average it lasts 4 to 6 years, but it can run anywhere from 2 to 10 years (health.gov.au).
Menopause itself is one point in time: your final period, confirmed once you've gone 12 months without one.
During perimenopause, the levels of oestrogen and progesterone made by your ovaries go up and down. That's why periods become irregular, heavier or lighter, and why many women start to notice other changes, including in their sleep.
Perimenopause symptoms: what's common
Every woman's perimenopause is different. About 1 in 2 women report mild to moderate symptoms, around 1 in 4 have symptoms that affect daily life, and around 1 in 4 have none (health.gov.au).
Common changes include:
- changes to your periods
- hot flushes and night sweats
- changes in sleep
- joint and muscle aches
- bladder changes
- mood changes
- brain fog or forgetfulness.
Not every change in this stage of life is perimenopause. Some can have other causes, which is one more reason to talk to your GP about anything that's bothering you. Jean Hailes has a free perimenopause and menopause symptom checklist you can fill in and take to your appointment.
How sleep changes in perimenopause
The most common sleep complaint during the menopause transition is waking in the night (Baker and colleagues, 2018). Women also describe taking longer to drop off and waking too early (Sleep Health Foundation), and waking up feeling unrefreshed (Jean Hailes).
Why it happens
There's rarely one cause. It's usually a few things stacking up.
- Changing hormones. Shifts in oestrogen and progesterone are a recognised contributor to disrupted sleep (Baker and colleagues, 2018).
- Hot flushes and night sweats. In one lab study, an awakening happened alongside 69% of hot flushes (Baker and colleagues, 2018). Women often wake just before a flush starts (Sleep Health Foundation).
- Bladder changes. More trips to the loo means more chances to wake and lie there.
- Snoring and breathing changes. Snoring and pauses in breathing during sleep become more common after menopause, and in women they're more often missed (Baker and colleagues, 2018).
- A full life. Jean Hailes' CEO calls it the “midlife collision”: work, children, ageing parents and money worries, all landing at the same time as hormonal change (Jean Hailes).
Light sleep, deep sleep and why mornings feel heavy
Sleep runs in cycles of about 90 minutes. Most of your deepest sleep happens in the first three hours of the night, and sleep gets lighter towards morning (Sleep Health Foundation).
Everyone has brief arousals through the night. Most of the time you don't notice them.
What changes for many women in perimenopause is how easily those light moments turn into full wake-ups. Research on exactly how deep sleep itself changes in the menopause transition is mixed (Baker and colleagues, 2018). Either way, broken sleep can leave you waking after eight hours in bed feeling you need three more.
That's also why so many women find themselves wide awake at 3am. By then you've had most of your deep sleep, so a hot flush, a full bladder or a busy mind has an easier job of waking you. In perimenopause, there are simply more of those nudges, on a night that's already lighter.
Evening habits that can help
These come from the Sleep Health Foundation, Jean Hailes and the Department of Health. Pick two or three that suit you, instead of trying them all at once.
- Dim the lights a couple of hours before bed. Darkness and dim light in the evening support your body clock. Get bright light in the morning too (Jean Hailes).
- Keep the bedroom cool. Light cotton sheets with layers you can throw off easily (Sleep Health Foundation).
- Give alcohol and caffeine a curfew. Jean Hailes suggests cutting back on caffeine and stopping alcohol three to four hours before bed (Jean Hailes). Alcohol can help you drop off but tends to disrupt sleep later in the night (Alcohol and Drug Foundation).
- Finish heavy meals about two hours before bed (Jean Hailes).
- Build a wind-down you look forward to. The same few steps each night: makeup off, teeth, a book, lights out. Your brain learns the cue.
- Park the to-do list. Write tomorrow's jobs on a notepad before bed, so your mind doesn't need to hold them in the middle of the night.
- Keep your wake-up time steady. Even after a rough night, getting up at the same time helps reset your rhythm.
- Move during the day. Regular exercise helps, but avoid high-intensity exercise, like running, in the hour before bed (Jean Hailes).

If you wake in the night
- Turn the clock around. The Sleep Health Foundation's Dr Moira Junge suggests resisting the urge to check the time (Jean Hailes).
- Leave the phone where it is. The scroll lights you up and gives your mind more to chew on.
- Try slow breathing or a relaxation exercise. Both are on Jean Hailes' list of relaxation techniques.
- Get up if it's been about 20 minutes. Do something quiet in dim light somewhere else, then go back to bed when you feel sleepy (Sleep Health Foundation).
- Be kind to yourself. In Dr Junge's words, good sleep “doesn't have to come in one big uninterrupted chunk”.
When to talk to your GP
Sleep changes in perimenopause are common, but you don't have to put up with them. Talk to your GP if:
- your sleep has been off for more than a couple of months
- it's affecting your work, relationships or safety, such as feeling drowsy when driving
- you've tried the habits above and nothing has shifted
- someone has noticed you snoring loudly, gasping or stopping breathing in your sleep
- your legs feel restless or jumpy at night and it keeps you awake
- you're not feeling like yourself in your mood
- you have heavy bleeding, bleeding between periods or after sex.
Your GP can look at what's behind it and talk you through the options, including hormonal and non-hormonal treatments (health.gov.au), and a referral to a sleep clinic or a psychologist trained in a structured, drug-free sleep program if needed (Sleep Health Foundation).
Take your Jean Hailes symptom checklist and a week of sleep notes to the appointment. Healthdirect's free helpline, 1800 022 222, has a registered nurse available 24 hours a day, 7 days a week.

Frequently asked questions
When does perimenopause start?
There's no set starting point, and the timing is different for every woman. Perimenopause lasts 4 to 6 years on average and can run anywhere from 2 to 10 years. It runs until about 12 months after your final period, which is when menopause is confirmed.
Is waking in the night a sign of perimenopause?
It can be one sign, but it isn't proof on its own. Waking in the night is the most common sleep complaint in the menopause transition. Sleep is also naturally lighter in the early hours for everyone, so alcohol, a full bladder, a snoring partner or a busy mind can all play a part. If it's new and ongoing, talk to your GP.
Why does perimenopause affect sleep?
Fluctuating oestrogen and progesterone, hot flushes and night sweats, bladder changes, and more snoring or breathing pauses in sleep can all break up the night. Midlife pressures like work, family and caring for parents often add to it.
What are the most common perimenopause symptoms?
Changes to your periods, hot flushes and night sweats, sleep changes, joint and muscle aches, bladder changes, mood changes and brain fog are among the most common. About 1 in 4 women have no symptoms at all.
How do I get back to sleep when I wake in the night?
Avoid checking the clock or your phone, try slow breathing or a relaxation exercise, and if you're still awake after about 20 minutes, get up and do something quiet in dim light until you feel sleepy. Keep your wake-up time the same the next morning.
How long do sleep changes last in perimenopause?
It varies. Perimenopause itself usually lasts 4 to 6 years, and some symptoms continue after menopause. You don't need to wait it out: your GP can help you find what's behind your sleep changes and what can help.
When should I see a doctor about perimenopause and sleep?
See your GP if poor sleep lasts more than a couple of months, affects your daily life, or comes with loud snoring, gasping, restless legs, changes in your mood or unusual bleeding.
