Restless Legs Syndrome (RLS) can make it difficult to relax at night, leaving you tossing and turning, and struggling to get the sleep you need. The urge to move your legs may feel overwhelming, and the discomfort often gets worse when you try to rest.
You can start with simple changes, such as establishing a steady sleep routine, reducing caffeine intake, and staying active throughout the day. If low iron plays a role, supplements may help restore balance.
When symptoms are more severe, medications and advanced therapies can bring real relief.

Lifestyle changes and supplements can ease mild symptoms
Medications and professional care provide more substantial relief when needed
Restless legs syndrome is a neurological condition that often disrupts sleep and daily comfort. It involves unusual leg sensations and an urge to move, and can be linked to other health issues, such as iron deficiency, sleep apnea, or Parkinson’s disease.
Identifying symptoms, causes, and risk factors helps you recognize when to seek treatment at a sleep clinic or from a specialist.
Restless legs syndrome (RLS), also known as Willis-Ekbom disease, is a neurological disorder that affects movement. You feel an uncontrollable need to move your legs, usually when sitting or lying down.
This urge often worsens in the evening or at night, making it difficult to fall asleep or stay asleep. RLS is considered both a movement disorder and a sleep disorder.
It commonly leads to insomnia, fragmented sleep, and daytime fatigue. Because symptoms improve with movement, you may find temporary relief by walking, stretching, or shifting positions.
RLS is not rare. Studies indicate that it affects approximately 5–10% of adults in the United States.
It can appear at any age, but it becomes more common after middle age and is slightly more frequent in women. Sleep studies may be used to assess the extent to which RLS is disrupting your sleep.
The primary symptom of RLS is a strong urge to move your legs while at rest. You may notice uncomfortable sensations described as:
These feelings usually occur in the lower legs but can also affect the arms. They often worsen in the evening, making it harder to fall asleep.
Nighttime leg twitching, also known as periodic limb movements, is a common condition. Diagnosis is based on your medical history and reported symptoms.
A sleep clinic may ask about how often symptoms occur, whether movement helps, and how much your sleep is affected. Blood tests may be ordered to check for iron deficiency or related conditions.
A sleep study can also help rule out other sleep disorders, such as sleep apnea.
The exact cause of RLS is not fully understood. Research suggests it may involve a dopamine imbalance in the brain, which affects how nerves control movement.
This is similar to what happens in Parkinson’s disease, which explains why some of the same medications are used in treatment. RLS often runs in families, suggesting a genetic link.
It may also be triggered or worsened by conditions such as:
Lifestyle factors like smoking, heavy caffeine use, or alcohol can aggravate symptoms. Certain medications, including some used for epilepsy or depression, may also make RLS worse.
Your risk increases with age, but children can also experience it, sometimes mistaken for “growing pains.” People with chronic conditions such as kidney disease or a history of stroke or TIA may also be more likely to develop restless legs.
Managing restless legs syndrome often begins with daily habits that reduce symptoms and improve sleep. Minor but consistent adjustments to your routine can help alleviate discomfort and promote a more restful night’s sleep.
Good sleep hygiene plays a crucial role in managing restless leg syndrome. Aim for a consistent sleep schedule by going to bed and waking up at the same time every day.
This helps regulate your body’s internal clock and reduces nighttime restlessness. Create a calm sleep environment.
Keep your bedroom dark, calm, and quiet. Avoid screens and bright lights before bed since they can interfere with melatonin production.
Simple relaxation practices also help. Try a warm bath, light stretching, or reading before bed to ease muscle tension.
If you wake during the night, avoid lying awake for long periods. Instead, get up briefly and return to bed when drowsy.
Regular exercise can help reduce restless leg symptoms, but the timing and intensity are crucial. Moderate activities, such as walking, swimming, or cycling, for 30 minutes most days, can improve circulation and sleep quality.
Avoid heavy workouts close to bedtime, as they may exacerbate symptoms. Stretching is beneficial before bed.
Focus on your calves, hamstrings, and thighs. Gentle yoga poses, such as forward bends or leg stretches, can relax tight muscles.
Some people also find relief with short movement breaks during the day. Standing, walking, or light stretching when symptoms flare can quickly ease discomfort.
Pairing these habits with warm baths or massages may provide additional relief.
What you eat and drink can influence restless legs. Caffeine, nicotine, and alcohol often make symptoms worse, especially in the evening.
Limiting or avoiding these substances can reduce nighttime restlessness. Low iron or vitamin D levels are sometimes associated with restless legs syndrome.
Consult your doctor to determine if testing and supplementation are suitable for you. Foods rich in iron, such as lean meats, beans, and leafy greens, may also help support healthy levels.
Stay mindful of hydration and balanced meals. Eating too close to bedtime or consuming heavy, spicy foods can disrupt sleep.Maintaining a simple, consistent diet that avoids known triggers may help alleviate nighttime discomfort and enhance sleep quality.
Iron plays a key role in restless legs syndrome because low iron levels in the brain can worsen symptoms. Correcting iron deficiency through supplements may reduce restlessness, but treatment depends on accurate testing, proper dosing, and careful monitoring.
You should start by checking your blood iron levels before beginning any treatment. Doctors often measure serum ferritin, which reflects the amount of stored iron, and may also examine transferrin saturation.
A ferritin level below 50–75 µg/L is often associated with restless leg syndrome symptoms. Iron deficiency does not always indicate anemia.
Many people with restless legs syndrome have normal hemoglobin levels but still exhibit low ferritin levels. This is why testing is essential even if your blood count looks normal.
Your provider may also review medications and health conditions that affect iron absorption. If you have kidney disease, frequent blood loss, or a poor diet, you may be at higher risk for low iron.
Identifying these factors helps guide the development of the right treatment plan.
Iron can be taken in two primary forms: oral supplements and intravenous (IV) therapy. Oral iron, such as ferrous sulfate or ferrous gluconate, is usually the first option.
It is inexpensive and widely available, but absorption can be limited, especially when taken with calcium, caffeine, or certain medications. IV iron is sometimes recommended when oral supplements are ineffective or poorly tolerated.
This method delivers iron directly into your bloodstream, potentially improving symptoms more quickly. Most research showing a benefit for restless legs has used IV iron rather than oral pills.
You may also be advised to take vitamin C with oral iron to improve absorption. Doses and schedules vary, so it is important to follow medical guidance rather than self-treating.
Iron supplementation requires careful monitoring to avoid both under-treatment and overload. Your doctor will likely recheck your ferritin and iron levels after several weeks or months to determine if the therapy is working.
Side effects of oral iron include stomach upset, constipation, and dark stools. IV iron may cause temporary flu-like symptoms or, in rare cases, allergic reactions.
Serious complications are uncommon when treatment is supervised. You should never take iron supplements without consulting a doctor and obtaining medical advice.
Excessive iron can accumulate in organs such as the liver and heart, potentially leading to long-term health issues. Regular follow-up ensures that your treatment remains both effective and safe.
Medications can help alleviate uncomfortable sensations in your legs and improve your sleep quality at night. Different drug classes target symptoms in different ways, and each comes with its own benefits and risks.
Gabapentin and pregabalin are anti-seizure drugs often used when symptoms are moderate to severe. They work by calming overactive nerve signals that may trigger restless leg syndrome.
Gabapentin enacarbil, a long-acting form, is usually taken once daily in the evening. Standard gabapentin may be used in lower doses, especially in people with kidney disease.
Pregabalin is another option that has been shown to improve sleep and reduce leg discomfort. Common side effects include dizziness, drowsiness, and swelling in the legs or feet.
These drugs are less likely than dopamine-based drugs to cause “augmentation,” which is when symptoms worsen over time. Because of this, many specialists recommend gabapentin or pregabalin as first-line choices for long-term treatment.
Dopaminergic agents act on dopamine pathways in the brain. You may recognize drugs like pramipexole, ropinirole, levodopa, and carbidopa.
These medications can give quick relief and are often effective for reducing nighttime symptoms. Pramipexole and ropinirole are taken in low doses before bedtime.
They can improve both the urge to move your legs and your sleep quality. Rotigotine, a patch not covered in detail here, works similarly.
Levodopa combined with carbidopa is sometimes used for intermittent symptoms. However, daily use often leads to augmentation, where symptoms start earlier in the day or spread to other body parts.
Other side effects may include nausea, lightheadedness, and daytime sleepiness. Because of these risks, doctors usually reserve levodopa for occasional use and rely more on pramipexole or ropinirole for ongoing treatment.
Opioids are considered when other medications fail or when symptoms are severe. Oxycodone combined with naloxone is an approved option in some countries.
Low doses can alleviate discomfort and enhance sleep, particularly in individuals who have not responded to dopaminergic medications. Other opioids, such as methadone or tramadol, may also be used in some instances.
These are usually prescribed only under close supervision because of the risks of dependence, constipation, and drowsiness. Opioids do not cause augmentation, but they are not the first choice due to safety concerns.
If you need them, your doctor will aim for the lowest effective dose and monitor you closely for side effects.
Some newer treatments for restless legs syndrome focus on stimulating nerves or using non-drug methods to calm symptoms. These approaches may be helpful when standard medications are ineffective or when side effects become a concern.
Neurostimulation devices use mild electrical pulses to target nerves in your legs. One option, bilateral high-frequency peroneal nerve stimulation, involves wearing a device before going to bed.
It delivers controlled stimulation that may reduce the urge to move your legs and improve sleep quality. This therapy is still considered a relatively new approach so access may be limited.
Some patients benefit from using it nightly, while others find relief with less frequent use. Studies suggest that it may help reduce discomfort without the risk of augmentation associated with certain medications.
Smart devices, including AI-driven wearables and sleep rings, are being tested to track movements and provide feedback. These tools help you and your doctor monitor symptoms more accurately than a standard sleep study alone.
They are not replacements for medical care but can support long-term management.
Non-drug strategies can also reduce symptoms. Stretching, yoga, and light aerobic exercise can help calm restless sensations when practiced consistently.
You should avoid heavy workouts close to bedtime, as they can sometimes worsen symptoms. Relaxation practices, such as deep breathing, progressive muscle relaxation, or mindfulness meditation, may help lower stress, which often exacerbates RLS.
Maintaining a regular bedtime routine and limiting caffeine and alcohol consumption also support better sleep. Some people find benefit from warm baths, leg massages, or using heating pads before bed.
These methods may not eliminate symptoms, but they can reduce their disruption.
Seeking professional help can make it easier to identify the cause of restless leg syndrome (RLS), rule out other conditions, and develop a personalized treatment plan tailored to your needs. You may require testing, monitoring, or effective management of your symptoms.
You should consider consulting a specialist if your symptoms significantly interfere with your sleep, daily activities, or mood. RLS that occurs more than a few nights a week often requires medical evaluation.
A doctor may order blood tests to check iron levels, as low ferritin and transferrin saturation are associated with RLS. If your levels are low, treatment may include oral or intravenous iron.
Specialists can also review your medications. Drugs such as antihistamines or certain antidepressants may worsen symptoms.
Adjusting or replacing these medications can sometimes reduce discomfort. If you are pregnant, have kidney disease, or have a family history of RLS, evaluation is critical.
These factors can increase the likelihood of more severe or persistent symptoms.
A sleep clinic, such as Gwinnett Sleep, provides access to trained sleep medicine professionals who can evaluate complex cases. Clinics often use sleep studies (polysomnography) to measure brain activity, leg movements, breathing, and heart rate during the night.
Sleep studies help confirm whether your symptoms are caused by RLS, periodic limb movement disorder (PLMD), or another sleep disorder like sleep apnea. Identifying the correct condition ensures you receive the proper treatment.
In some cases, sleep clinics may also use home sleep testing. While less detailed than in-lab studies, these tests can still provide helpful information about movement and breathing patterns.
The results guide treatment options, which may include medication, iron therapy, or non-drug approaches, such as nerve stimulation devices. Clinics also provide education on lifestyle changes and follow-up care.
Managing RLS often requires a combination of medical treatment and lifestyle adjustments. Medications such as gabapentin, pregabalin, or iron therapy may be prescribed based on your test results and overall health.
You may also need to limit alcohol, caffeine, and certain medications that make symptoms worse. Regular exercise, consistent sleep schedules, and stress reduction can support long-term control.
Some people benefit from non-drug therapies, such as compression devices, vibration pads, or nerve stimulation. Sleep specialists may recommend these.
These options can reduce symptoms without the risks linked to long-term medication use.
Restless leg syndrome doesn’t have to control your nights or drain your days. With the right combination of lifestyle changes, medical therapies, and professional support, many people find significant relief from the uncomfortable sensations and sleeplessness that RLS causes. Whether improving sleep hygiene, correcting iron levels, starting medications, or exploring advanced therapies like neurostimulation, there are effective solutions to fit different needs.
