Perimenopause Restless Legs at Night: Why It Happens and What to Track
That urge to move your legs the moment you lie down has a name — and low iron may be part of it. Here's what restless legs in perimenopause needs.
You finally lie down, and your legs will not settle. There is an itch you cannot scratch, a crawling urge to move, a restlessness that only walking seems to relieve — and then it starts again the moment you stop. If perimenopause has added this to your nights, it has a name, a cause worth checking, and more you can do about it than you might think.
What restless legs actually is
Restless legs syndrome is a recognised condition, not a quirk. The NHS describes an overwhelming urge to move the legs, often with uncomfortable feelings such as tingling, throbbing or itching, that is worse in the evening and at night and eases when you move. The relief-with-movement is the signature — it is what separates it from cramps or general aches.
It shows up more around perimenopause for several overlapping reasons: hormonal changes, the low iron that is common in midlife women with heavier or irregular periods, and the simple fact that disrupted perimenopausal sleep makes everything at 2 a.m. louder.
The check worth asking for: iron
The NHS links restless legs syndrome to iron deficiency anaemia among other causes. That matters because it is one of the more treatable contributors — a blood test can check it, and correcting low iron can genuinely help. If your periods have been heavy or irregular in perimenopause, this is worth raising specifically rather than assuming the cause is only hormonal.
Restless legs, or something else?
| Pattern | What it feels like | The tell |
|---|---|---|
| Restless legs syndrome | Urge to move, crawling or tingling, worse at rest and at night | Eases when you move |
| Leg cramps | Sudden, painful muscle tightening | Painful spasm, not an urge |
| General aches | Steady soreness in muscles or joints | Not relieved by movement |
If aching rather than restlessness is the issue, our guide to joint pain and stiffness fits better. If the main problem is waking and not getting back to sleep, see perimenopause insomnia.
What helps
The NHS self-help list is practical and worth trying before anything else:
- Do exercise during the day, keep a regular sleep schedule, get your bedroom right, and try applying heat or massaging your legs.
- Don't have caffeine later in the day, drink alcohol before bed, eat late, exercise in the evening, or use screens right before sleep.
- Ask about iron, especially if your periods have been heavy or irregular.

Frequently Asked Questions
Can perimenopause cause restless legs?
Restless legs syndrome — a strong urge to move the legs with uncomfortable crawling, tingling or throbbing that eases with movement and is worse at rest and at night — is commonly reported in perimenopause. Hormonal changes and low iron can both contribute, and disrupted sleep makes it more noticeable. It is a recognised condition with its own assessment and treatments.
What does restless legs syndrome feel like?
The NHS describes an overwhelming urge to move the legs, often with uncomfortable sensations such as tingling, throbbing or itching. Symptoms are worse in the evening and at night, ease when you move, and can seriously disrupt sleep. Some people also get it in the arms.
Is restless legs linked to low iron?
It can be. The NHS links restless legs syndrome to iron deficiency anaemia among other causes, which is why a GP may check your iron levels. It is one of the more treatable contributors, so it is worth asking about rather than assuming the cause is only hormonal.
What can I do about restless legs at night?
NHS self-help includes exercising during the day, keeping a regular sleep schedule, a good bedroom environment, applying heat or massaging the legs, and stretching — while avoiding caffeine later in the day, alcohol before bed, late meals, evening exercise and screens before sleep. Track what helps so you can see the pattern.
When should I see a GP about restless legs?
The NHS advises seeing a GP if restless legs syndrome is stopping you sleeping, affecting your mental health, or the self-help measures have not helped. A GP can check for causes such as low iron and discuss treatment, so it is worth raising rather than enduring broken sleep.
How is this different from ordinary leg cramps?
Cramps are a sudden, painful tightening of the muscle. Restless legs is an urge to move with uncomfortable sensations that ease when you do move — the relief-with-movement is the tell. Tracking which one you have helps because they are assessed and managed differently.
