Menopause and Sleep: Why It Falls Apart, and What Restores It
Hot flashes, 4 a.m. wakes, and a sudden inability to sleep through the night. The hormonal and behavioural strategies that actually help.
Up to 60% of women in perimenopause and menopause report new or worsened sleep problems. The picture is consistent: falling asleep is still possible, but staying asleep — especially through the early hours — becomes a nightly struggle.
What is going on
Falling oestrogen destabilises temperature regulation, leading to hot flashes that fragment sleep. Falling progesterone removes a natural GABA-ergic sedative the body has relied on for decades. The result is lighter, shorter, more fragile sleep.
What helps
- Sleep the bedroom cool — 18–20°C, with breathable bedding. This is non-negotiable in our climate.
- Cut alcohol on weeknights. It dramatically amplifies hot flashes.
- Strength training twice a week — independently shown to improve sleep depth in menopausal women.
- Discuss HRT with a clinician. For appropriate candidates, it resolves sleep disruption faster than any behavioural intervention.
When CBT-I is the right tool
If the sleep disruption persists after temperature and hormonal factors are addressed, CBT-I works as well in menopausal women as in any other group. It does not require you to be on HRT to benefit.
On not waiting
Menopausal insomnia is one of the most under-treated conditions in our field — partly because women are often told it is 'just part of it'. It is not. It is treatable, and the earlier you intervene, the less the pattern entrenches.
