Why Sleeping in the Heat Is So Hard

(Especially in perimenopause and beyond)

Updated 18 June 2026

It's been a warm one lately and I'll be honest with you, I've been waking up around 4am feeling like I'm on fire. Not a hot flush exactly, just... hot. Sticky. Wide awake when I absolutely should not be.

Sound familiar? I'd be amazed if it doesn't. Since starting HRT, I thought I was through this disturbed sleep.

If you're in your 40s or 50s and navigating perimenopause or menopause, sleeping in warm weather can feel so difficult. And I don't mean a bit uncomfortable. I mean lying there at 3am, sheets wet, twisted, whilst you wonder if you'll ever feel cool again.

But, it's not just the weather. You’ve got a lot going on in your body, and once you understand it, you can start doing something about it.

Why sleep gets harder as we age

Our sleep patterns genuinely change as we get older. The internal clock that tells us when to feel tired (your circadian rhythm) becomes less reliable as hormones shift. You might find yourself falling asleep earlier, waking up earlier, or just sleeping more lightly than you used to.

If you add a warm night to that mix, you've got a problem.

The research on this isn't exactly cheerful reading. Between 39 and 47% of people in perimenopause experience sleep disorders. That figure rises to 35 to 60% after menopause. So if you're lying awake thinking you're the only one, you really aren't, there are lots of folks going through the same thing.

Hormones: Why your sleep suffers in menopause

Two hormones in particular are contributing a lot of damage to your sleep right now.

Progesterone is basically your body's natural sedative. It has a calming, sleep-inducing effect, which is lovely when you have plenty of it. In perimenopause and menopause, levels drop, and so does your ability to fall asleep easily or stay asleep through the night.

Oestrogen does a few different jobs, including helping to regulate your body temperature and supporting the neurotransmitters that manage your sleep/wake cycle. When oestrogen drops, you're more likely to overheat, feel lower in mood, and have genuinely worse quality sleep. Night sweats and hot flushes are the obvious symptoms, but even without those, a lot of women just run warmer at night than they used to.

If you're on HRT and taking progesterone, a quick tip: take the progesterone at night. It genuinely helps with sleep and you'd be surprised how many people aren't doing this. Worth a conversation with your GP or menopause specialist if you're not sure.

It's not just hormones, either

Perimenopause and menopause tend to land at a time when everything else is also happening. Teenagers who are awake to the early hours. Ageing parents who might need more from you. A career that's probably busier than ever. The occasional knee pain caused by desk sitting..

Stress, aches, bladder changes, new medications. All of it affects sleep. So if you're having a terrible night and you're not even particularly warm, this is probably why.

What you can actually do about it

But, enough of the why, here's what can help you get a bit more shuteye.

Cool your environment

Keep curtains closed during the day to stop the room heating up in the first place. Open windows once the air outside is cooler than the air inside, which in the UK is usually sometime around midnight when you've already given up on sleep entirely.

Bamboo bedding is genuinely worth it. It's breathable, moisture-wicking, and it doesn't trap heat the way cotton does. I use the Panda set and my husband is very much a convert.

On the fan front, I've had my Dyson Cool Tower Fan for years and it's brilliant, but it is an investment. I've recently been eyeing up the Silentnight Airmax 3400 Tower Fan from Boots, which Good Housekeeping recommended and comes in at a much friendlier price. It's got a sleep mode, a 9 hour timer, remote control, and 90 degree oscillation so it covers the whole room. That sleep mode is the one I'd be most interested in personally. A quiet, gentle breeze rather than feeling like you're sleeping next to a wind turbine. I haven't tried it yet but it's on order and I’ll update this, once I’ve had a good test of it! UPDATE I’ve got the Silentnight Airmax 3400 and I love it. We are now using that and not the Dyson!

A cold flannel on the back of your neck or forehead before bed works too. It’s low tech, zero cost (if you already own a flannel, and I’m guessing you do!), weirdly effective.

Wear the right thing

It’s not always less is more here, nakedness might not be the solution. Natural fibres, cotton, bamboo, linen, help wick away moisture and stop that lovely sticky-skin situation. If sleeping in the buff is your preference, absolutely no judgement. But if you find you're waking up clammy, a lightweight breathable layer might actually help more than you'd think.

Support your body through the day

Drink water. Properly, throughout the day, not just a quick downed pint from the tap before bed. Your body handles temperature regulation much better when it's hydrated.

Cold shower before bed can help bring your core temperature down enough to make sleep easier.

After dark, try to avoid alcohol. I know, that might feel out of the question. But it really does disrupt the second half of your sleep even if it helps you drop off initially. Same goes for caffeine after midday and sugary things in the evening, blood sugar spikes are not your friend at 3am.

Block out the rest

I'm a big fan of Loop earplugs and a blackout eye mask (I use the MyHalos one). I've tried an embarrassing number of ear plugs over the years. I have not yet found a pair that's comfortable, reusable, AND blocks out all sound. If you have, please tell me immediately. The Loop ones are the best I've found so far but they're not perfect.

You're not imagining it. And you're not alone.

This is a genuinely rubbish combination: changing hormones, life stress, and warm nights. It's a lot. But there are things that help, and most of them don't require a prescription or a complete life overhaul.

Start with one or two changes and see what shifts. Sometimes that's enough.

And if you're lying awake at 4am reading this on your phone right now, hi. I see you. Go put a cold flannel on your neck and I'll see you on the other side.
