Why Menopause Makes You So Hot at Night (and What Actually Helps)

It’s 3 am. You’re wide awake, the duvet is on the floor, and you feel like you’ve been sleeping next to a radiator that won’t switch off. For a lot of women going through perimenopause or menopause, this is just an average night. The sudden rush of heat, the damp pillow, lying there too warm to sleep but too tired to actually deal with it. It’s disruptive, exhausting, and more common than you might think.

According to our 2026 Sleep Survey, nearly 1 in 5 women (19.8%) say menopause has had the biggest impact on their sleep. Among women aged 55 to 64, that rises to almost 1 in 4. And more than 1 in 4 women who experience disrupted sleep (27.3%) say being too hot is a regular cause.

The good news is that there’s a lot you can do to help, and we’re going to walk you through it.

During perimenopause and menopause, oestrogen levels drop. This affects the part of the brain that controls body temperature, making your body far more sensitive to even small changes in temperature. The result is hot flushes and night sweats: sudden, intense waves of warmth that can wake you from deep sleep and leave you drenched.

The NHS describes hot flushes as one of the most common symptoms of menopause, affecting around 75% of women. They can last anywhere from a few months to 10 years or longer, and they tend to be worse at night when your body temperature naturally dips and then rises again.

And just to be clear – this isn’t you being oversensitive. It’s your body responding to a significant hormonal shift. The British Menopause Society recommends a range of approaches, from HRT to lifestyle changes. Talking to your GP is always a good first step if symptoms are significantly affecting your quality of life.

1. Cool your room down before you go to bed

The ideal sleep temperature sits between 15.6–18.3°C. Open a window ahead of time, run a fan, or use a smart thermostat to keep things consistent overnight. Even a couple of degrees makes a difference when hot flushes are already raising your core temperature.

2. Keep cold water and a damp cloth within reach

A glass of cold water on the bedside table is the simplest thing that still works. A damp flannel in a small bowl with a few ice cubes nearby is a reliable old trick for when a flush hits at 2 am.

3. Switch to a mattress that doesn’t trap heat

Traditional memory foam is known for retaining heat beneath you. Cooling mattresses use breathable open-cell foams and moisture-wicking covers to actively manage temperature as you sleep. Gel mattresses draw heat away from the body rather than letting it build up. They won’t stop flushes, but they remove a layer of the problem.

4. Replace heavy bedding with lighter, natural layers

A lower tog duvet (4.5 to 7) gives you enough cover without building heat. Cotton and bamboo absorb moisture far better than synthetics. See our stay cool when sleeping guide for a breakdown of which materials work best for hot sleepers.

5. Give yourself and your partner separate duvets

If you share a bed, one duvet trying to cover two people with very different temperature needs is fighting a losing battle. Two single duvets means you can go for a lightweight option while your partner keeps their heavier one. No compromise, no duvet hogging, no waking each other up.

6. Choose sleepwear made from natural or moisture-wicking fabrics

Loose-fitting cotton or bamboo pyjamas let your skin breathe. Moisture-wicking fabrics, originally designed for sport, are now available in proper sleepwear styles and handle night sweats more effectively than anything synthetic. Anything tight or synthetic is worth avoiding.

7. Cut the common evening triggers

Alcohol, spicy food, and caffeine after midday can all intensify hot flushes. Eating a heavy meal too close to bedtime doesn’t help either. None of this means never enjoying them, just being more deliberate about timing.

8. Take a lukewarm shower before bed

You’re trying to gently lower your core temperature before sleep. A cold shower can actually backfire, causing your body to generate heat in response. Aim for warm enough to be comfortable, cool enough to leave you feeling settled rather than flushed.

9. Build in a proper wind-down before sleep

Stress and anxiety can make hot flushes more intense, so arriving at bedtime already wound up tends to make things worse. Even ten minutes of quiet reading or slow breathing can shift things. Keep exercise to earlier in the day; vigorous activity in the evening raises your core temperature at exactly the wrong moment.

Menopause is a transition, not a permanent setting. Hot flushes and night sweats do ease for most people over time, especially with the right support, lifestyle adjustments, and sleep setup.

If you haven’t already, speak to your GP about your options. HRT, cooling gels, and other treatments have come a long way and can make a significant difference for many women.

And in the meantime, a cooler room, the right mattress, and some breathable bedding are a simple, effective place to start.
