Also known as: Restless Legs Syndrome
Restless legs syndrome (RLS) causes an uncomfortable urge to move the legs, usually worse in the evening and at rest. It significantly disrupts sleep.
RLS affects approximately 5-10% of adults and is characterized by an irresistible urge to move the legs, usually accompanied by uncomfortable sensations described as crawling, tingling, or pulling.
Symptoms follow a circadian pattern, worsening in the evening and at rest. Movement temporarily relieves the discomfort, creating a cycle that severely disrupts sleep.
Iron deficiency — even without anemia — is the most important modifiable risk factor. Brain iron levels play a crucial role in dopamine function, and supplementation can significantly improve symptoms.
There are several possible reasons you may be experiencing Restless Legs. Here are the most common ones.
Low brain iron impairs dopamine function. Even ferritin levels below 75 ng/mL may contribute to RLS.
RLS runs in families, with several gene variants identified that affect iron metabolism and dopamine signaling.
Up to 25% of pregnant women experience RLS, likely from hormonal changes and iron demands.
Kidney failure affects iron metabolism and is strongly associated with RLS.
These approaches may help manage restless legs at home. Always consult a healthcare provider if symptoms persist or worsen.
Meat, spinach, beans, and fortified cereals support iron levels.
Moderate exercise improves RLS symptoms. Avoid vigorous exercise close to bedtime.
Massaging or rubbing the legs provides temporary relief from uncomfortable sensations.
Clinical diagnosis based on symptom criteria (urge to move, worse at rest, worse in evening, relieved by movement). Blood tests for iron and ferritin.
See a doctor if symptoms occur most evenings, significantly disrupt sleep, or cause daytime fatigue that affects functioning.
Steps you can take to reduce the likelihood of experiencing restless legs.
Maintain adequate iron levels
Exercise regularly (but not near bedtime)
Avoid caffeine and alcohol in the evening
Establish consistent sleep schedule
