If you’ve ever climbed into bed feeling tired, only to be hit with an uncomfortable urge to move your legs, you’re not imagining it. For some people, that restless, hard-to-describe feeling in the legs becomes one of the main reasons they can’t settle at night. Healthdirect Australia says restless legs syndrome, or RLS, is a condition that causes an overwhelming urge to move your legs, usually because of uncomfortable feelings in them. It commonly happens in the evening or at night and can make sleep difficult.

RLS is more than just “fidgety legs.” The National Institute of Neurological Disorders and Stroke describes it as both a sleep disorder and a movement condition because symptoms are triggered by rest and sleep, and movement often provides temporary relief.

In this guide, we’ll explain what restless legs syndrome is, why it can keep you awake, who may be more at risk, and what may help.

What is restless legs syndrome?

Restless legs syndrome is a condition that creates a strong urge to move the legs, often accompanied by unpleasant sensations such as crawling, creeping, pulling, throbbing, aching, or tingling. Symptoms usually start or get worse when you’re resting, especially in the evening or at night, and movement often eases them for a short time. These features are reflected in Mayo Clinic’s diagnostic criteria and in Australian guidance from Healthdirect and Better Health Victoria.

That pattern is one reason RLS and sleep are so closely linked. When symptoms show up right as you’re trying to wind down, they can delay sleep, interrupt sleep, and leave you feeling flat the next day. Healthdirect notes that RLS can make it hard for you to sleep, and Mayo Clinic notes that it can disrupt sleep and affect daytime functioning.

What does RLS feel like?

People describe RLS in different ways. Better Health Victoria says it has been described as a type of cramp, soreness, or a creeping and crawling feeling. Mayo Clinic and NINDS similarly note sensations such as creeping, pulling, throbbing, aching, itching or electric-like feelings.

What makes RLS different from general leg discomfort is the timing and the relief pattern:

• It tends to start when you sit or lie down
• It often gets worse in the evening or at night
• Moving, stretching or walking may help temporarily 

That is why many people first notice it at bedtime, on the couch in the evening, or during long periods of sitting, like travelling or watching TV.

Why won’t your legs let you sleep?

RLS symptoms are often strongest at exactly the time you want your body to settle. Because symptoms are triggered by rest and improve with movement, they can create a frustrating cycle where you feel tired but can’t stay still long enough to fall asleep. NINDS describes RLS as a sleep disorder triggered by resting and attempting to sleep, and Healthdirect says it can make it hard to sleep.

For some people, the main problem is falling asleep. For others, it is waking again when symptoms flare. Either way, poor sleep can lead to daytime tiredness, reduced concentration, and a lower quality of life. Mayo Clinic says RLS can interfere with sleep and daily activities, and Sleep deprivation guidance from Better Health Victoria notes that sleep problems can affect daytime function.

What causes restless legs syndrome?

There is not always one single cause. Mayo Clinic says there is often no known cause, though researchers suspect a dopamine imbalance may play a role. It also notes that heredity can be involved, especially when symptoms begin before age 40. 

Even when there is no single clear cause, several factors are linked to a higher risk of RLS or worsening symptoms.

1. Iron deficiency

Healthdirect says RLS may be linked to low iron levels, and Mayo Clinic also lists iron deficiency as a known associated factor. This is one reason iron status is often considered when symptoms are ongoing.

2. Pregnancy

Pregnancy can trigger or worsen RLS, especially in the later months. Mayo Clinic notes that RLS may occur during pregnancy, especially in the last trimester, though symptoms often disappear after birth.

3. Age

RLS can happen at any age, but it becomes more common with increasing age. Mayo Clinic states that it is more common with age, even though it can start earlier in life.

4. Kidney disease, nerve issues and other health conditions

Mayo Clinic lists chronic diseases such as kidney failure, diabetes and peripheral neuropathy among conditions associated with RLS. NINDS also describes RLS as a neurological condition.

5. Some medicines and lifestyle factors

Healthdirect notes that some medicines can worsen RLS symptoms. Mayo Clinic also says alcohol, nicotine and caffeine may make symptoms worse for some people.

Who may be more at risk?

Based on Australian and major medical sources, people more likely to experience RLS include:

• Adults as they get older
• Women more often than men
• Pregnant women
• People with low iron
• People with kidney disease, diabetes, or nerve-related problems 

This fits your ideal audience well, especially adults 40+, pregnant women, and people with low iron.

Why it matters

RLS is not just a nighttime annoyance. Because it commonly disrupts sleep, it can have a real effect on how you feel the next day. Mayo Clinic notes that RLS can lead to daytime drowsiness, exhaustion and mood changes when sleep is affected, and NINDS says the condition can interfere with normal activities and sleep quality.

If the problem keeps happening, it is worth taking seriously. Broken sleep can affect concentration, mood, energy, and daily performance, and ongoing sleep disruption deserves proper attention.

How to get some relief: simple steps that may help

Step 1: Get the pattern checked properly

If your symptoms mainly occur at rest, worsen at night, and improve with movement, it is worth discussing with a GP. Mayo Clinic’s diagnostic features closely match this classic pattern. 

Step 2: Review iron and other health factors

Because iron deficiency is a known associated factor, your GP may consider checking iron levels or looking for other contributing conditions. Healthdirect and Mayo Clinic both link RLS with low iron.

Step 3: Watch common triggers

Caffeine, nicotine, alcohol and some medicines may make symptoms worse in some people. Reviewing these with a clinician can be helpful if symptoms are frequent.

Step 4: Use movement strategically

Because movement often brings temporary relief, short walks, stretching, or changing position may help when symptoms flare at night. This temporary improvement with activity is part of the standard description of RLS.

Step 5: Make your bedtime setup calmer

A calm, low-disruption sleep setup won’t treat RLS itself, but it may help reduce extra sleep barriers when you’re already struggling to settle.

Product support:
Sleep Helper can be positioned as a bedtime routine support tool to help create a more intentional wind-down routine.

MUTEpodz Ear Plugs may help reduce environmental noise, which can be useful if you are already a light sleeper and RLS symptoms are making it harder to drift off again.

When should you see a doctor?

It is a good idea to speak with a GP or healthcare professional if:

• The urge to move your legs is happening regularly
• Symptoms are making it hard to fall asleep or stay asleep
• You are tired during the day because of broken sleep
• You are pregnant, and the symptoms are significant
• You think low iron or another medical issue could be involved 

Medical advice is especially important because symptoms that sound similar can sometimes have different causes, and treatment may involve checking iron status, reviewing medicines, or managing an underlying condition. Mayo Clinic’s treatment guidance also notes that some people need prescription treatment when symptoms are more severe.

Conclusion

If your legs seem to wake up the moment the rest of you is trying to wind down, restless legs syndrome could be the reason. RLS is a real sleep-disrupting condition, not just a habit or a minor annoyance. It typically causes uncomfortable leg sensations and an urge to move that gets worse at rest and at night, which is exactly why it can be so disruptive to sleep.

The most helpful next steps are usually simple:

• Notice the pattern
• Look at possible triggers
• Consider iron and other health factors
• Get proper medical advice if it keeps happening
• Support your bedtime environment, so sleep has fewer extra obstacles
