Menopause and sleep: why the nights get shorter

During menopause, up to sixty percent of women report sleep problems. It's not just about hot flushes. What changes hormonally, what is proven to help — and why one cause is almost always overlooked.

How common this is

Sleep problems are among the most frequently reported complaints during menopause. In the review by Baker and colleagues from 2018, forty to sixty percent of women report difficulty falling or staying asleep depending on the phase. Compared to the years before, this is roughly a doubling.

Complaints typically increase during the transition phase, when cycles become irregular — often years before the last menstrual period. The study by Kravitz and colleagues in over twelve thousand middle-aged women showed the pattern clearly: the further the hormonal transition had progressed, the more frequent the sleep complaints.

What changes hormonally

Both oestrogen and progesterone affect sleep. Progesterone has a calming effect via its breakdown products on the same system targeted by sleep medications — when it drops, falling asleep becomes harder. Oestrogen in turn influences body temperature regulation and serotonin metabolism. Its decline narrows the temperature window in which the body feels comfortable.

This gives rise to night-time hot flushes. They typically unfold like this: a brief rise in core body temperature, then sweating, heart pounding, waking up. This is followed by chills from the evaporating sweat — which keeps you awake even longer. Many women wake up several times a night without consciously noticing the hot flush.

The overlooked cause

With the transition, women's risk of obstructive sleep apnoea also rises significantly — nocturnal breathing pauses that fragment sleep. Progesterone helps keep the throat muscles stable; when it drops, that protection disappears. On top of that, fat distribution shifts towards the trunk and neck.

The tricky part: in women, sleep apnoea often looks different from the textbook picture. Instead of loud snoring, the main symptoms are fatigue, difficulty falling asleep, mood swings and morning headaches. These complaints tend to be attributed to menopause — and the breathing disorder goes undetected. Anyone who is persistently exhausted despite getting enough sleep should bring this up with a doctor.

What the research says about treatments

The best-evidenced approach is cognitive behavioural therapy for insomnia. In 2019, Drake and colleagues compared it in a study of postmenopausal women against sleep restriction and education alone — the behavioural therapy came out on top, and the effects lasted after treatment ended. It also works when hot flushes persist.

Hormone therapy can significantly reduce night-time hot flushes and thereby improve sleep. It involves weighing up benefits and risks — a decision for a gynaecologist, depending on age, time since last period and medical history. Guthrie and colleagues showed in 2018 that non-hormonal approaches also work: certain antidepressants and behavioural methods measurably improved sleep problems. This content does not replace medical advice.

What you can influence yourself

With temperature, every degree counts. Seventeen to nineteen degrees in the bedroom, breathable cotton or linen instead of synthetic fabrics, a thinner duvet or two separate duvets instead of one shared one. Many women find a layering system easier to manage — one you can adjust during the night.

Alcohol intensifies hot flushes and fragments the second half of the night — that's the lever with the fastest visible result. Strength training is doubly worthwhile: it counteracts the muscle and bone loss that accelerates during this phase, and studies also show it improves sleep quality. Regular sleep times and morning light stabilise a rhythm that has already become more sensitive.

How the YUTHI app helps you

Hot flushes, sleep and mood are connected — but hardly anyone can say afterwards exactly how. In the app you log your night-time hot flushes, and they sit alongside sleep duration, wake periods, resting heart rate and what you ate and drank in the evening. After a few weeks, you can see which evenings lead to quieter nights.

Vito and Vita work with what your data actually shows, not with averages. If your fatigue doesn't match your sleep duration, they raise the possibility of a breathing disorder and suggest getting it checked out. And they remind you that this phase can last years — the goal is to make it measurably more manageable, not just to track it away.
