What is restless leg syndrome?

Restless leg syndrome (RLS), also known as Willis-Ekbom disease, is characterised by an irresistible urge to move the legs, typically accompanied by uncomfortable sensations described as crawling, pulling, or tingling. Symptoms are worse at rest and in the evening or night, and are temporarily relieved by movement. RLS significantly disrupts sleep and quality of life. It can be primary (idiopathic) or secondary to iron deficiency, pregnancy, kidney disease, or certain medications.

What are the most important first steps in managing RLS?

Investigating and addressing secondary causes is essential before managing symptoms. Iron deficiency is one of the most common and treatable causes — even low-normal ferritin levels (below 50–75 µg/L) can contribute to RLS and may respond to iron supplementation. Reviewing medications that can cause or worsen RLS (certain antidepressants, antihistamines, antipsychotics) is also important.

Can complementary approaches help RLS?

Acupuncture has limited but positive evidence for symptom reduction in RLS. Massage of the legs, compression stockings, and heat or cold application provide temporary symptomatic relief for many people. Reducing caffeine, alcohol, and nicotine — particularly in the evening — can reduce severity. Magnesium supplementation is used clinically and may help in those with deficiency.

How does RLS affect sleep and what can help?

RLS is a major disruptor of sleep onset and maintenance, with significant downstream effects on mood, cognition, and quality of life. Sleep hygiene — consistent sleep-wake timing, cool bedroom environment, and a wind-down routine — provides a helpful framework. Avoiding screen use and stimulating activities close to bedtime is particularly important as RLS symptoms typically peak in the late evening.

Quick answer

Restless leg syndrome causes uncomfortable sensations in the legs — typically at rest or at night — compelling movement that disrupts sleep. Iron status, magnesium, dopamine-supporting nutrition, and acupuncture show evidence for symptom relief alongside medical assessment.

Do any of these feel familiar?

Restless leg syndrome is experienced as an uncomfortable, irresistible urge to move the legs — most commonly in the evenings or at night, or when resting and sitting still
The sensations are difficult to describe but are often characterised as crawling, tingling, burning, aching, or a deep internal restlessness
Movement brings temporary relief; stillness brings the sensations back
The condition is most disruptive to sleep: many people describe lying in bed unable to stay still, getting up to walk around repeatedly, and struggling to stay seated during long journeys, films, or meetings
