Menopause and perimenopause cause sleep problems for most women — trouble falling asleep, waking through the night, and night sweats that jolt you awake. It is not in your head: falling progesterone and swinging estrogen directly disrupt sleep. Understanding the cause is the first step to fixing it.
The three ways hormones disrupt sleep
- Falling progesterone — it normally has a calming, sleep-promoting effect, so less of it means lighter, more broken sleep.
- Night sweats — estrogen swings disrupt temperature control, and a hot flash at night wakes you drenched.
- Higher night-time cortisol — the reason so many women wake at 3 or 4am, wide awake.
What helps
The same foundations that help all perimenopause sleep: a cool dark room, consistent bed and wake times, less evening alcohol and caffeine, a proper wind-down, and magnesium in the evening. For the full playbook, see perimenopause and sleep.
If night sweats are the main thing waking you, treating the hot flashes helps the sleep — see perimenopause hot flashes.
Talk to your doctor if sleep problems are severe or long-running. HRT helps many women, and persistent insomnia has treatments worth exploring.
The bottom line
Menopause genuinely causes sleep problems, through progesterone, night sweats and cortisol. They respond well to the right habits — and to treating the night sweats behind them. More in the wellness guide.
