Here is the short version, because at 1am nobody wants a biology lecture. Restless legs at night come down to how your brain handles two things, dopamine and iron. The timing follows your body clock, which is why the feeling waits until you finally stop moving.
The everyday triggers are the part that surprises people most. An afternoon coffee, a glass of wine with dinner, or a medication you take for something else can each quietly turn the volume up. The rest of this page walks through all of it.
Why are my legs restless at night and not during the day?
The cruel part of restless legs is the timing. Your legs behave themselves all day, then turn on you the moment you want to rest. This is not bad luck, and it is not a sign that you cannot switch off properly.
There is a reason it waits until the evening, and it is not about how well you relax. Restless Legs Syndrome follows your body clock, a daily rhythm where the symptoms build through the evening and peak overnight, exactly when you are trying to wind down.
Lying down makes it worse because rest itself is the trigger. The restlessness gets louder when your body is still and quiet, and it eases the moment you move.
Long films, flights, and car trips can set the legs off just as readily as bed can, for the same reason. It is not your mattress and it is not your bedtime routine. It is the stillness.
If you have ever wondered whether you are simply not relaxing hard enough, the brain chemistry says otherwise. Dopamine, the messenger chemical that helps control movement, naturally dips in the evening for everyone.
Willpower has nothing to do with it, and here is why. In people prone to Restless Legs Syndrome, that ordinary evening dip is enough to set off the urge to move, because the system that uses dopamine does not run smoothly. That is why your legs feel restless at night in particular.
What causes restless legs at night?
What causes restless legs at night is rarely one single thing. It is usually a mix of how your brain uses dopamine and iron, the genes you were born with, and a handful of everyday triggers stacking up together. For most women the honest answer is several of these at once. Here is each piece in plain terms.
Low iron stores, the most common fixable cause
The most hopeful thing to know is that one of the most common causes of restless legs is also the most fixable. Iron is the raw material your brain needs to use dopamine properly. Many people with Restless Legs Syndrome are running low on stored iron, even when a routine blood test calls them normal.
If you do one thing after reading this, make it this number. Your serum ferritin is the measure of stored iron. The threshold sleep specialists use is higher than the one most general practice still works to, so a result called normal may not be optimal.
A ferritin test is the single most useful thing to ask your GP for if your legs are restless at night. It is worth reading the full picture of iron, ferritin, and restless legs before that appointment.
A family history you may not have named
If your mother paced the hallway at night, you may have inherited more than her looks. Restless Legs Syndrome runs strongly in families, and most people with it can point to a parent, sibling, or grandparent who had the same restless, cannot-settle feeling.
A family history does not doom you to bad nights. That relative was often the one with jumpy legs or the fidgets, named that way around the family long before anyone gave it a medical label. The tendency is built in, but the triggers below are the part you can actually move.
Pregnancy and the hormones that follow
For a lot of women, restless legs first turned up during pregnancy and then never quite left. Pregnancy is one of the clearest triggers for Restless Legs Syndrome, partly because it draws down iron stores and partly because of the hormonal shifts involved.
For many women the symptoms settle once the baby arrives. For others they dig in and come back years later, often louder, around perimenopause and menopause. If your restless nights seem to track your hormones, you are reading the pattern correctly.
Medications that can stir your legs up
It is worth knowing that a tablet you take for something else may be quietly winding your legs up at night. Several common medications can trigger or worsen Restless Legs Syndrome.
The fix here is a question, not a panic. The usual suspects include some older antihistamines (the sedating kind), certain antidepressants, a few anti-nausea medications, and cold and flu tablets with pseudoephedrine. Take a list of what you use to your GP and ask, because a simple swap sometimes makes a real difference.
Caffeine, alcohol, and the everyday triggers
The triggers most within your control are also the ones most people miss. Caffeine and alcohol both wind restless legs up, and the timing is sneakier than it sounds.
Here is the encouraging part: unlike your genes, every one of these is something you can test. An afternoon coffee or a single glass of wine with dinner can still be loud at midnight, and stress, a warm bedroom, and long stretches of sitting all add to the pile. Change one for a fortnight and watch what happens.
Health conditions worth ruling out
Once in a while, restless legs are a messenger for something else, which is exactly why a proper check is worth it. Restless Legs Syndrome is more common in people with kidney disease, diabetes, and an underactive thyroid.
For most women reading this, restless legs are a standalone nuisance with nothing sinister behind them. But because they can occasionally point to something treatable, legs that are brand new, severe, or affecting only one side deserve a real conversation with your doctor.
Is it actually Restless Legs Syndrome? The four-part pattern
You can get a strong sense of whether your night-time restlessness really is Restless Legs Syndrome by checking it against four features doctors look for. If your experience matches all four, Restless Legs Syndrome is very likely. If it matches only one or two, something else may be going on, and that is worth knowing just as much.
- You feel an urge to move your legs, usually alongside an uncomfortable sensation. People describe it as crawling, pulling, aching, fizzing, or simply a need to move that is hard to put into words.
- The urge starts or gets worse when you are resting. Sitting still or lying down brings it on.
- Moving helps, at least while you keep moving. Walking, stretching, or rubbing the legs eases it, and the relief fades once you stop.
- It is clearly worse in the evening and at night than it is in the morning.
If all four ring true, what you are dealing with is almost certainly Restless Legs Syndrome, and the causes above are the right place to start looking. The relief of simply naming it should not be underrated.
If the feeling is mainly sharp pain, mainly a hard cramp, or does not track the time of day, it may be something else. Leg cramps, a circulation problem, or nerve pain each point to a different conversation with your GP. A restless-legs problem and a cramp problem are solved in completely different ways.
Why do my legs feel restless at night more than they used to?
If your restless legs have crept from a mild annoyance to the thing wrecking your sleep, there are a few predictable reasons, and most are not a sign of anything dangerous. Restless Legs Syndrome tends to get louder with age, with falling iron stores, and, for many women, with the hormonal change of menopause.
For women in their forties and fifties, the timing of that worsening is rarely a coincidence. Iron stores can quietly drop with heavy perimenopausal periods, and the hormonal shifts of menopause appear to amplify Restless Legs Syndrome in their own right.
This is the most common reason women who managed mild symptoms for years suddenly find their legs unbearable the moment they get into bed. If that is your story, you are not alone in this, and the link between restless legs and menopause explains what is going on.
There is one more reason restless legs get worse that genuinely surprises people: the medication meant to calm them. A class of drugs long prescribed for Restless Legs Syndrome, the dopamine agonists, can backfire over time.
The worsening can sneak up on you over months or years. The drug makes the symptoms stronger and starts them earlier in the day, a pattern doctors call augmentation. If your legs got worse after you started a medication for them, raise it with your doctor rather than putting up with it.
The encouraging part is that getting worse is not a one-way street. Restless legs respond to the triggers you can control and to the iron correction your GP can guide you through. For a practical, ordered plan, how to stop restless legs at night walks through what to try and in what sequence.
What the research actually shows
If you have read this far hoping for something that is not a drug, here is the most encouraging evidence on the table. Targeted overnight compression has real clinical data behind it, and the most relevant trial put it head to head against a standard medication.
One study stands out. Kuhn and colleagues (2016), published in the Journal of the American Osteopathic Association, ran an eight-week trial in 30 adults with moderate-to-severe symptoms. It compared targeted foot compression against ropinirole, a standard prescription medication for Restless Legs Syndrome.
The result is worth holding onto. On the Clinical Global Impression scale, the compression group recorded a 90 per cent improvement against 63 per cent for ropinirole. In that trial, targeted compression came out about 1.4 times more effective than the drug, with no augmentation risk.
On the medication side, the thinking has shifted in a way worth knowing about. The 2024 American Academy of Sleep Medicine guidelines revised their position on the dopamine agonists, ropinirole and pramipexole among them, because of the long-term augmentation risk.
What this means for you is simple. The guidelines now steer toward other options, and none of this makes medication the wrong choice for everyone. It means the conversation you have with your doctor in 2026 is a different one than a decade ago, and you can ask for the current thinking.
What does not have trial evidence is worth a mention too, because the forums are full of it. A bar of soap under the sheets, tonic water before bed, mustard from the fridge: these get passed hand to hand because restless nights make people desperate, not because they shift the scores.
Have you tried tonic water? Yeah, plenty of women with restless legs have tried that too. The honest causes are the ones set out above, and the honest things to try are the ones with real data behind them.
What Stillr is, and isn’t
If reading this has left you wanting an answer that is not another tablet, that is the exact want Stillr was built around. Stillr is a drug-free overnight compression sleeve, worn on both legs, with no electronics, no batteries, and nothing to charge.
What it does borrow is the evidence. Stillr is built around the targeted-pressure mechanism behind the strongest non-drug research for Restless Legs Syndrome, using a patent-pending compression structure. It comes in two sizes: Regular (Australian women’s 5 to 8) and Large (Australian women’s 8.5 to 11, or men’s 7 to 10).
The founders’ price is the reason to look now: AUD $149 for the first 500 pairs while Stillr is pre-launch in Australia. Every pair includes a 30-Night Sleep Trial, a full refund if it does not improve your sleep.
Stillr is not a medication, not a cure, and not a treatment for any disease. It is a wellness product, built around what the research suggests the body responds to.
Understanding why your legs are restless at night is the first step toward trusting your body again when you lie down. If a drug-free option, on your own terms, is what you have been hunting for, join the founders’ list at stillr.com.au and we will tell you the moment your size opens.
