Restless Legs at Night: Why It Happens and What Helps
The day is fine. Then you sit down after dinner, or switch off the light, and your legs start. A crawling, pulling or fizzing feeling builds deep in the calves until you have to get up and walk it off. Restless legs at night can turn bedtime into something you dread, and the lost sleep spills into the next day.
This guide explains why the evening is the worst time, what you can try tonight, and when it is worth getting checked.
Why restless legs at night get worse
Restless legs syndrome follows the body clock. The urge to move usually builds from late afternoon and peaks in the hours around midnight, then fades towards morning. Stillness is the other trigger. So a long drive, a film or lying in bed are exactly the moments when it shows up.
Traditional practice explains the timing in its own terms. At night the body is meant to draw its resources inward so the muscles and sinews can rest. If those resources are running low, the legs are the first place to show it. That is why tiredness, heavy periods, pregnancy and illness so often make restless legs at night worse.
An evening routine that may help you settle
Small changes to the last few hours of the day often matter more than anything done earlier. Try these for a couple of weeks before judging them:
- Keep caffeine to the morning. Coffee, tea, cola and chocolate all count, and their effect lasts well into the evening.
- Go easy on alcohol and nicotine at night. Both are common aggravators, even when they seem to help you drop off.
- Take a short walk after dinner. Moderate movement earlier in the evening helps. Hard exercise close to bedtime can do the opposite.
- Stretch your calves before bed. Hold each stretch for thirty seconds, then massage the calves firmly for a few minutes.
- Have a warm bath or shower. Warmth settles the legs for many people. A few people find cool works better, so test both.
- Keep the mind busy when you have to sit. A crossword or a conversation tends to hold the urge off better than passive screen time.
- Keep regular hours. Going to bed at the same time each night steadies the body clock. Traditional advice is to be asleep before about 11 pm.
Foods to favour in the evening
Diet will not switch restless legs off. Even so, the sleep monographs we work from make specific suggestions for the evening meal and the hours before bed:
- Calming, sleep-friendly foods such as turkey, bananas, figs, dates, yoghurt and milk. A warm glass of milk with a little honey is the classic choice.
- A light soup for dinner, such as lima beans cooked with turkey and sage.
- A small cup of mulberry tea, or celery and beet-top tea taken about two hours before bed.
- Toasted amaranth tea. Toast a quarter cup of amaranth in the oven until lightly brown, then steep it in a cup of hot water for five minutes and sip it slowly.
- Magnesium and calcium-rich foods through the day: green leafy vegetables, avocado, broccoli, almonds, soy foods and brown rice.
The same sources suggest keeping some foods away from bedtime. Bacon, ham, sausage, aged cheese, chocolate and sugary snacks are the main ones. They are fine earlier in the day.
Restless legs at night in pregnancy and menopause
Two life stages bring restless legs at night to the surface more than any other. In pregnancy, it often appears in the last three months, when iron demands peak and sleep is already broken. Most women find it settles within weeks of the birth. Meanwhile, the evening routine above is the safest place to start, and an iron check with your midwife matters.
Around menopause, restless legs tends to arrive with night sweats, a racing mind and lighter sleep. In traditional terms this is the heat-at-night pattern: feet that need to be outside the covers and a body that cannot cool down. Keeping the bedroom cool, eating dinner earlier and skipping the evening glass of wine often help on both fronts. Our guide to menopause and sleep covers that side in more detail.
What to do when it starts in bed
First, get up rather than lying there fighting it. Walk around, stretch the calves against a wall, or rub the legs firmly. Then go back to bed once the urge has passed. Some people keep a heat pack or a cold pack by the bed and use whichever works for them.
Also, keep a simple diary for two weeks. Note the time it started, what you ate and drank, how active you were and how tired you felt. Patterns tend to appear, and the diary is useful to bring to your doctor or to us.
Where acupuncture fits
Many people with restless legs at night come to us after the basics have been checked. Treatment is planned around the pattern behind the legs, whether that is depletion, heat at night, or heavy and sluggish circulation. You can read more about acupuncture for restless legs at our Adelaide CBD clinic. Responses vary, and it sits alongside your doctor’s care rather than replacing it.
When to see a doctor
Book a doctor’s appointment if restless legs at night is happening most evenings, if it started after a new medicine, or if you are pregnant. Ask specifically about an iron check, including ferritin. Get same-day help if one leg is swollen, hot, red or painful, as that can be a blood clot. The Sleep Health Foundation guide to restless legs is a reliable Australian reference.
Frequently asked questions
Why are restless legs at night worse than during the day?
The urge follows the body clock and peaks in the evening and around midnight. Stillness is the other trigger, and bedtime combines both.
Does a warm bath really help?
For many people it does, at least for the evening. A few find cool water works better, so it is worth testing both.
Should I take magnesium for restless legs?
Magnesium-rich foods are a sensible start. Before taking any supplement, check with your doctor or pharmacist, especially if you have kidney problems or take other medicines.
