In the Study of Women's Health Across the Nation, among 1,449 women with hot flashes and night sweats, the median total duration was 7.4 years. They persisted a median of 4.5 years after the final period.
For the women whose symptoms began before their periods stopped, the median course ran beyond 11.8 years. Median means half of them had it for longer.
Almost every woman reading this was told some version of give it a year or two. Now do the arithmetic on 7.4 years of broken sleep.
What the number actually represents
SWAN is a large, long running study of women through the menopausal transition, and this analysis followed women who reported frequent hot flashes and night sweats. Two findings matter.
First, the total duration. A median of 7.4 years, meaning half the women had symptoms for longer than that.
Second, and this is the one that gets left out, when they started predicts how long they run. Women whose symptoms began while they were still having periods, which is the majority, had the longest course of all, a median exceeding 11.8 years. The women who started early are the ones told most confidently that it is early days.
Why this is not just about being hot
If hot flashes only meant a warm few minutes, the advice to wait would be defensible. That is not what they cost.
They come at night. You wake at three, drenched, change what you are wearing, and lie there until five or six. Do that four nights a week for years and everything else on the list gets worse: the concentration, the word finding, the temper, the appetite regulation, the drive, the resilience. Sleep is not a symptom sitting alongside the others. It is the floor under them.
Meanwhile the years pass. Bone loss is fastest from about one year before your final period to two years after it. Fat is moving inward and muscle is falling away during the same window, with the metabolic consequences that follow. And the intimacy symptoms behave completely differently from the flashes, because they do not fade with time, they advance.
So ride it out is not a neutral instruction. It is a decision to spend a defined number of years of your life in that state, and to spend them in the window where the underlying changes are moving fastest.
What actually works, briefly and honestly
Hormone therapy reduces hot flashes and night sweats by roughly 70 to 90 percent, and for these symptoms it is the most effective option there is. Started within about ten years of menopause, usually before 60, the risks stay low. That timing is not a detail, it is the whole risk conversation, and it is covered separately.
If you cannot take estrogen, or do not want to, that is no longer the end of the discussion. A newer class of medicine that is not a hormone at all cuts flashes substantially in trial data, and several older non hormonal options have real evidence behind them. That too has its own piece.
What does not work is a long list, and much of it is sold aggressively. The Menopause Society's 2023 position statement explicitly does not recommend paced breathing, cooling techniques, trigger avoidance, or supplements and herbal remedies for this purpose. A 2013 Cochrane review of 43 trials found no benefit from phytoestrogens of any type. In a sham controlled trial of 327 women, real and sham acupuncture produced about the same 40 percent improvement.
That last figure deserves a moment. The placebo response in hot flash trials runs between 20 and 50 percent. Which is exactly why anything sold to you on the strength of testimonials rather than a controlled trial should be treated as unproven, however sincere the person selling it.
Seven years is not a phase. It is a decade of your fifties. The question is not whether you can endure it, because you can. The question is why you would, when the alternative is a proper assessment and a decision made on evidence.
The question worth asking instead
Not how long will this last. You have the number now. The useful question is: given my history, my timing and my risks, what are my actual options, and what does each one do for me?
That is answerable, but only for you specifically, and only by someone who knows your breast history, your clot history, your bone risk, your blood pressure and what has already been tried. It is not answerable by a forum or by a page on the internet, including this one.
If you have been waiting it out and the arithmetic above changed how that feels, that is worth acting on. Take it to the specialist and find out what applies to you, in English or Dutch, within days.
