Short answer: through the menopausal transition, the dominant cause of bad nights is not anxiety: it is vasomotor symptoms, which fragment the night with repeated wakings. But past a certain point a self-sustaining insomnia sets in, held up by the same mechanisms as any other — and a randomised trial showed it responds to behavioural treatment even while the hot flushes persist. Treating the heat and treating the insomnia are two separate jobs, and neither excuses the other.

The confusion that costs years

The usual reasoning is linear: hot flushes wake you, so as long as they last, sleep will stay bad, so you wait. That is true at first. It stops being true later, and that is where the years go.

The review literature on sleep during the menopausal transition — including a review published in Nature and Science of Sleep in 2018 — draws the distinction. There is sleep disrupted by heat, and there is insomnia that, once established, maintains itself. The second does not wait for the first to stop.

Its maintaining mechanisms are those of any chronic insomnia: staying in bed longer to catch up, checking the clock, dreading bedtime, and a bed that has gradually become a signal for wakefulness rather than sleep. None of that is hormonal, and none of it will resolve hormonally.

What the trial showed

A randomised trial published in JAMA Internal Medicine in 2016 — one of the MsFLASH trials — compared telephone-delivered behavioural therapy for insomnia against a sleep education intervention, in peri- and postmenopausal women with vasomotor symptoms.

The result: insomnia improved significantly in the therapy group — and that improvement happened while the hot flushes themselves persisted.

That is the finding that changes the plan. Past a certain stage the insomnia has become a condition in its own right; it is treated as such, without waiting for the original symptom to go. And the treatment is the one for any chronic insomnia, which the AASM guideline and the European Insomnia Guideline place first-line: two-week diary, stimulus control, compressed sleep window.

On the heat, what you can handle at home

The aim isn't to prevent the flush — that is the medical conversation. It is to shorten the waking it causes, so the night reassembles faster.

What this page does not replace. Medical management of the vasomotor symptoms themselves — the options, the benefits and the risks — is a conversation for an appointment. Insomnia lasting more than three months calls for guided therapy. And window compression carries its own precautions: increased daytime sleepiness for one to two weeks, never below five hours, and an assessment first if you snore heavily.

How Sillon handles it

"Menopause" is one of the situations the app models explicitly, and it carries exactly this distinction as two cards. The first, "The heat that wakes you", treats the fragmented night. The second, "The insomnia that outlasts the flushes", triggers the full six-week protocol. They are offered only to the people they are for, and the dedicated path sequences them in that order.
