Why restless legs gets louder for women over 40
Putting a name to it is the first relief. If you have spent years assuming the crawling, creeping, have-to-move feeling in your legs was just stress or a fidgety habit, it helps to know it has a name. Restless Legs Syndrome is a recognised neurological condition, and it is roughly twice as common in women as in men. International research (Broström and colleagues, 2023, in the Journal of Sleep Research, pooling 97 studies) found it in about 4.7 per cent of women versus 2.8 per cent of men.
The reason your 40s feel like the tipping point is that age stacks on top of sex. Restless Legs becomes more common as we get older, and women in their 40s and 50s show up again and again in the data (Song and colleagues, 2024, Journal of Global Health). The thing you half-noticed in your 30s before a long flight, or after a couple of wines, is now most nights of the week.
You probably know the shape of it already. You are tired enough to sleep, you lie down, and your legs pick that exact moment to start up. You move them and the feeling eases for a few seconds, then it comes back. By the time you finally drop off, half the night is gone, and the alarm does not care.
Is it your hormones? Restless legs and menopause
The timing that feels suspicious is real. If your legs got worse around the same time the hot flushes, night sweats, and 3am wake-ups arrived, that overlap is not a coincidence. A 2008 study by Wesström and colleagues in the journal Climacteric surveyed 5,000 Swedish women. It found Restless Legs was more common among women with vasomotor symptoms, the hot-flush and night-sweat group, during the menopause transition.
What that buys you is permission to stop blaming yourself. This is not poor sleep hygiene or too much screen time, although those do not help. It is a genuine biological pattern that lands on a lot of women at exactly this stage of life. The link between restless legs and menopause is well documented, even if no one mentioned it at your last check-up. There is a fuller breakdown in the restless legs and menopause guide, including why the prior-pregnancy connection matters.
The frustrating part is how quietly it travels. Most women in this window are managing the visible menopause symptoms and treating the legs as one more thing to put up with. They do not have to be.
The link between restless legs and hormones, in plain English
Understanding the why makes the legs feel less like a personal failing. Restless Legs comes down to two things your body manages quietly in the background. The first is dopamine, the chemical your brain uses to control movement signals. The second is iron, one of the raw materials it needs to make that dopamine in the first place. When either one is off, the urge-to-move feeling that defines Restless Legs can break through.
The timing makes more sense once you see where restless legs and hormones meet. Fluctuating oestrogen, the dramatic up-and-down of perimenopause rather than the steady low that comes after, appears to nudge the dopamine system in a way that lets the legs flare. It is the movement of the hormones, not simply the level, that seems to do it. That detail matters, and it explains a lot about why the obvious fix does not work, which we get to below.
The good news is that iron, the other half of this story, is the part most women can actually do something about. The menopause transition is a window where ferritin, your body’s stored iron, often shifts or sits in a grey zone. The 2024 American Academy of Sleep Medicine (AASM) clinical practice guideline now recommends correcting iron for adults whose serum ferritin sits below 100 micrograms per litre. That is well above the level most GPs flag as low. In plain terms: your iron can read as “normal” on the standard test and still be too low for your brain to make dopamine comfortably.
Why the medication path worries so many women over 40
Wanting to fix the legs without adding another prescription is a completely reasonable instinct, and the evidence now backs it. For two decades the standard answer was a dopamine drug like Sifrol or ropinirole. In 2024 the AASM guidelines reversed that position and recommended against those drugs as the first-line treatment, because the drugs themselves can make symptoms worse over time, a process called augmentation.
That reversal is a big deal for women your age. You are often already weighing up HRT, possibly something for mood or blood pressure, and you do not want to start a medication that the guidelines now warn can backfire. The good news is that the strongest non-drug evidence has been quietly building on the other side, and it does not interact with anything else you might be taking. There is a full rundown in the drug-free restless legs treatment guide.
This is also where the HRT question comes up, so let us be honest about it. HRT may genuinely help your hot flushes, your sleep, and your energy. What the research does not show is HRT reliably calming the legs themselves. Treat the legs and the menopause as two separate jobs, and you stop pinning your hopes on the wrong fix.
What actually helps restless legs in women over 40
A layered plan beats a single magic bullet, and most women find the legs go from disrupting sleep to background noise once a few of these stack up. Here is the order worth working through:
- Ask your GP for a serum ferritin test, and get the actual number. The 2024 AASM guideline supports correcting iron under 100 micrograms per litre, which is higher than most clinics flag. This is the single most useful thing you can do first.
- Cool the bedroom to around 18 to 20 degrees. This does double duty, easing both the night sweats and the legs. A fan, lighter sheets, and lighter pyjamas all earn their place.
- Audit caffeine and alcohol, especially after lunch. Both worsen Restless Legs at night, and both wreck menopausal sleep through their own routes, so cutting back pays off twice.
- Add targeted overnight compression. Of all the drug-free options, this is the one with the strongest published trial behind it. Kuhn and colleagues (2016) found targeted foot compression produced a 90 per cent improvement versus 63 per cent for the drug ropinirole, with no augmentation risk.
- Take a 20-minute walk after dinner, five nights a week. Gentle evening movement settles the legs for a lot of women and helps the rest of your sleep along the way.
- Talk to your GP about the legs and the menopause as separate plans. They are biologically linked, but lumping them together is how women end up on a dopamine drug on top of HRT, which the 2024 guidelines now caution against.
None of these require you to white-knuckle through another bad night. Worked through in order, they give you something to actually do, which beats lying there counting the hours.
What the research actually shows
Four pieces of evidence sit behind everything above.
Broström et al. (2023), Journal of Sleep Research. A systematic review and meta-analysis of 97 studies and 483,079 participants across 33 countries. Pooled prevalence was 4.7 per cent in women and 2.8 per cent in men, roughly a 1.7-to-1 skew, with prevalence higher in older adults.
Song et al. (2024), Journal of Global Health. A systematic review and modelling analysis estimating global Restless Legs Syndrome prevalence at about 7.12 per cent of adults, with prevalence rising with age. This is the broad “any qualifying symptom” figure; the share with severe nightly symptoms is smaller.
Wesström et al. (2008), Climacteric. A survey of 5,000 Swedish women aged 18 to 64, with a 70 per cent response rate. Overall Restless Legs prevalence was 15.7 per cent, and it was higher among women with vasomotor symptoms during the menopause transition. Notably, HRT use was not associated with lower Restless Legs prevalence.
Kuhn et al. (2016), Journal of the American Osteopathic Association. An eight-week randomised comparison of targeted foot compression against ropinirole in 30 adults with moderate-to-severe Restless Legs. Compression produced 90 per cent improvement on the Clinical Global Impression scale versus 63 per cent for the drug.
What Stillr is, and isn’t
Stillr is a drug-free overnight compression sleeve, worn on both legs, designed to replicate the targeted-pressure mechanism behind the strongest non-drug evidence for Restless Legs Syndrome. It is unisex, sized for adult feet, and currently pre-launch in Australia. Every pair comes with a 30-Night Sleep Trial, full refund if it does not improve your sleep. Reserve your pair on the founders’ list at stillr.com.au, where current pricing and sizing are listed.
Stillr is not a medication, not a cure, and not a treatment for any disease, including menopause. It is a wellness product, built around what the research suggests the body responds to, made for the women who want to settle the legs without adding another prescription to an already busy chapter.
