Menopause and Sleep: Insomnia, Night Waking and What Helps

It’s 3 am. You’re wide awake, the duvet is on the floor, and you’re too warm to drop off but far too tired to do anything about it. For a lot of women in perimenopause and menopause, that’s an ordinary Tuesday.

Sleep is often the first thing to go, and it can be the hardest thing to lose. Everything else gets harder without it. According to our 2026 Sleep Survey, nearly 1 in 5 women (20%) name menopause as one of the biggest influences on their sleep.

Heat gets most of the attention here, and it matters. It isn’t always the hot flushes themselves, though. A study that tracked 223 women in their forties every few months found that trouble sleeping because of feeling too hot rose as they entered the transition, with no matching rise in reported hot flushes or night sweats.

We asked Dr Zoe Williams, our resident sleep expert and an NHS GP, what women actually come to her with. It’s rarely the symptom you’d expect.

Even the women who have already worked out what’s behind it tend to lead with sleep. As Dr Zoe puts it: “A lot of women who do know it’s perimenopause or menopause will often say, look, I can deal with the hot flushes, I can deal with that symptom, but I just can’t deal with being so exhausted because I can’t sleep.”

Oestrogen and progesterone don’t only look after your monthly menstrual cycles. They also have a hand in body temperature, mood and the systems that keep you asleep once you’ve dropped off. As those levels fall and fluctuate during perimenopause and menopause, sleep is affected.

This is a real, measurable shift rather than a run of bad nights. A review in Nature and Science of Sleep found that sleep difficulties are linked to menopausal stage and changing hormone levels over and above the effects of getting older. It’s the transition doing this, rather than simply another birthday.

The same review reports that around 26% of women in the transition have symptoms severe enough to affect their days, which meets the clinical threshold for insomnia. A UK study of women born in 1946 found the odds of severe sleep difficulty were around two to three and a half times higher at most stages of the transition than for women who stayed premenopausal.

Sleep can also be an early signal. Researchers at UCSF followed 223 women aged 40 to 50 and found that trouble sleeping because of feeling too hot increased about six months after the first hormonal marker of the transition, without women reporting more hot flushes or night sweats. Their conclusion was that being too hot to sleep, separate from noticing a flush, may be one of the earlier signs. It’s a single study of a few hundred women, so treat it as a useful clue rather than a settled finding.

There’s a pattern many women describe. Falling asleep is fine. Staying asleep is the problem. You surface in the small hours, properly awake, then lie there while your brain works through a to-do list you didn’t ask for.

That’s sleep-maintenance insomnia, and it’s the type that shows up most often during the menopausal transition. Hot flushes are part of the story. Overnight sleep recordings covered in the Nature and Science of Sleep review show that flushes are often linked to measurable awakenings, with the time spent awake around them adding up to a meaningful chunk of the night.

There’s also a reason the small hours are harder than the first half of the night, and it’s the same for everyone. Dr Zoe explains it like this: “When you think about feeling sleepy, we can sometimes call it sleep pressure. That’s because a certain type of chemical has built up in the brain throughout the day. So, when you get to nighttime, that first half of the sleep, you’ve got lots of this chemical that keeps you feeling sleepy. Whereas the second half of sleep, for some people that’s kind of reduced. So, your natural sleepiness is reduced.” Hormones play into it too, as she goes on: “Early in the morning, cortisol, the stress hormone, starts to rise, which is normal and what it’s meant to do. Some people might be more sensitive to those changes in chemicals in the body and be less sleepy and more wakeful in that second half of the night.”

That’s also why everything else picks that moment to make itself known. As Dr Zoe puts it: “As you come out of one sleep cycle and go into a new one, that first bit of sleep is light sleep when you’re very easily rousable. So, if your bladder’s full, that’s when you’re going to wake up. If you’ve got pain, that’s when your pain is probably likely to start bothering you. If you’ve got things on your mind, that’s when your brain might start racing.”

Not every waking has a flush attached to it. Some women wake with no heat at all. Hormonal changes, mood and sleep disorders that become more common after menopause all play a part, which is why the answer isn’t always a cooler room.

Waking up at all isn’t the problem, either. Dr Zoe’s steer is to look at the pattern rather than the fact of it: “It’s normal to experience brief awakenings between sleep cycles, and many people won’t even remember them. If you’re waking briefly and falling straight back to sleep, it may not be affecting your overall sleep quality. However, if you’re waking frequently, struggling to get back to sleep or feeling exhausted during the day, it’s worth looking into.”

Over-the-counter sleep aids and melatonin are what a lot of women reach for first. The National Institute on Aging is clear that these can help for a short stretch, aren’t a fix for insomnia and shouldn’t be used long term. Worth a word with your GP or pharmacist before you come to rely on them.

One more thing worth naming. Once broken sleep has gone on for a while, worrying about sleep becomes its own problem.

It’s a well recognised pattern, and it responds well to treatment.

When oestrogen levels drop, the part of your brain that manages body temperature becomes far more reactive to small changes in heat. The exact mechanism isn’t settled, and the leading explanation is a problem with central temperature control triggered by falling oestrogen, as set out in StatPearls. A small study by Robert Freedman found that women with symptoms appear to have a narrower comfortable temperature range, so tiny rises in core temperature you’d once have slept through may be enough to set off a flush. At night, that lands badly, because your core temperature dips and rises as you sleep anyway.

Dr Zoe puts it simply: “Essentially, the hormones affect the brain’s ability to tolerate changes in temperature.”

Heat isn’t the whole of it either, as Dr Zoe points out: “One thing people forget is that it’s not just that people get hot and get flushes and get sweats. Some people can feel very cold as well, very cold and shivery, and people can fluctuate between the two. It can make for a very uncomfortable night when you’re really hot and sweating, and then you’re wet, and you feel really cold.”

The honest answer is that this lasts longer than most women are told. The Study of Women’s Health Across the Nation tracked more than 3,000 women and found that among those with frequent hot flushes and night sweats, symptoms lasted a median of 7.4 years, continuing for a median of 4.5 years after the final period. For some, it runs considerably longer.

Being too warm disrupts everyone’s sleep, and more so for women. In our 2026 Sleep Survey, 27% of women who have disturbed nights say being too hot is a regular cause, compared with 20% of men. If heat is your main problem, our guide to what causes night sweats covers the causes and fixes in full.

Mood changes, anxiety and low self-esteem are all recognised symptoms of perimenopause and menopause according to the NHS, and they have an obvious effect on sleep. Anxiety at bedtime makes falling asleep harder, and it makes a 3 am waking much harder to recover from.

Our survey data shows how common this is. A racing mind or busy head is the single most common reason women give for a disturbed night, named by 43% of those who sleep badly, well ahead of stress at 33% and heat at 27%.

Timing has a lot to do with it. Dr Zoe points out that this stage rarely arrives in a quiet year: “Perimenopause and menopause often coincide with a particularly demanding stage of life. Many women are juggling work, family responsibilities and caring for others, alongside carrying a significant amount of the mental load. All of these pressures can contribute to stress and make sleep difficulties even harder to manage.”

There’s a loop here. Poor sleep lowers your mood; a low mood makes sleep harder, and once you add hot flushes, it’s hard to tell which started it. You don’t have to untangle that on your own.

There’s no single fix here, and there are a lot of small things that add up. Some are about staying cool, and some are about giving your sleep a better chance in general. Be kind to yourself about how much you take on at once:

• Make the room cool before you get into bed: The ideal sleep temperature sits between 16°C and 18°C, cooler than most bedrooms. Open a window an hour before, or run a fan.
• Look at what’s underneath you as well as on top: Dense traditional memory foam holds heat against you all night, while cooling mattresses use breathable open-cell foams and gel mattresses draw warmth away.
• Go lighter and more natural with bedding: A lower-tog duvet in cotton or bamboo handles moisture far better than synthetics, and our cooling bedding is built for this. If you share with someone who runs cold, two single duvets mean neither of you has to compromise.
• Keep cold water and a damp flannel within reach: It sounds too simple to bother with. It works, and it saves you from getting up at 2 am.
• Protect your wind-down routine: Ten minutes of reading or slow breathing genuinely shifts how the next few hours go. The NHS also suggests regular sleep routines, relaxation and cutting back on alcohol.
• Watch your timing of caffeine, alcohol, big meals and naps: The National Institute on Aging suggests keeping caffeine out of the late afternoon, eating earlier, exercising earlier and skipping the late nap. It’s also blunt that alcohol won’t help you sleep, even in small amounts.
• Go to bed and wake up around the same time, weekends included: A regular schedule gives your body clock something to hold on to when everything else feels unpredictable.

Dr Zoe would add one more to that list, and it happens first thing rather than last thing.

For the nights you’re already awake, lying there willing it to happen tends to backfire. Dr Zoe’s advice is to give it a limit: “If you feel like you’ve been lying awake for around twenty minutes or more, it can help to get out of bed and do something quiet and relaxing in dim lighting until you feel sleepy again. This helps prevent your brain from associating the bed with frustration or anxiety about not sleeping.” Three things to avoid while you’re up, in her words: “Don’t touch your phone, don’t look at lights and don’t look at the clock.”

She’s direct about alcohol too, because it’s a common one at this stage: “People often think that alcohol helps them sleep, particularly women around the time of perimenopause and menopause might lean into that. Whilst it’s true that alcohol might help you get off to sleep, it actually is very disruptive to sleep quality, and you’re more likely to have awakenings even if you’re not aware of them.”

Our guide on how to keep cool at night goes into more detail on the cooling side than we have room for here.

If your sleep is affecting your days, your work or your relationships, that’s reason enough to book an appointment. You don’t need to reach a particular level of exhaustion first.

Dr Zoe sums up the two main routes: “HRT can be very effective at alleviating menopause symptoms that disturb sleep, particularly hot flushes and night sweats. It’s a first-line treatment for these symptoms and can significantly improve sleep as a result. Cognitive behavioural therapy for insomnia (CBT-I) is also an effective treatment for persistent sleep difficulties.”

NICE guidance says HRT should be offered for hot flushes and night sweats associated with menopause, and that menopause-specific cognitive behavioural therapy should be considered too, either alongside HRT or instead of it for women who can’t take it or would rather not. Since 2024, that includes night-time waking, which comes alongside flushes, which is a change from earlier guidance.

There’s also a newer option if HRT isn’t suitable for you. In March 2026, NICE recommended fezolinetant, the first non-hormonal treatment approved for moderate to severe hot flushes and night sweats, for use where HRT is unsuitable. HRT remains the first choice for most women, and this gives your GP something to offer if it isn’t an option for you.

Access to CBT varies by area, and NICE acknowledges that waiting times can be long, so it’s worth asking what’s available locally. The National Institute on Aging suggests checking that whoever delivers it has experience with women going through menopause. Do mention any snoring, gasping or breathing pauses too, as sleep-disordered breathing becomes more common after menopause and is treatable.
