If restless legs syndrome has no identifiable underlying cause, which initial management strategy is commonly recommended?

• A. Immediate opioid therapy
• B. Lifestyle modifications such as sleep hygiene and regular exercise
• C. Surgical intervention
• D. Avoid all physical activity

Answer: (B)

When restless legs syndrome occurs without an identifiable underlying cause, the best initial approach is nondrug, lifestyle-based management that improves sleep quality and reduces symptoms. Emphasizing good sleep hygiene—regular bed and wake times, a comfortable sleep environment, and avoiding stimulants like caffeine, nicotine, and alcohol especially in the evening—can significantly lessen nighttime symptoms. Adding regular, moderate aerobic exercise and gentle leg stretching or walking during the day helps reduce restlessness without the risks associated with pharmacologic therapies. Warm baths, leg massages, and relaxation techniques before bed can also ease discomfort. If iron stores are low, iron supplementation may be beneficial since iron supports dopaminergic pathways involved in RLS. These measures are preferred first because they are safe, can improve sleep and functioning, and address the condition without immediately resorting to medications with greater risk. Opioid therapy is not a first-line option due to dependence risk, surgical interventions are irrelevant, and avoiding physical activity would not help—in fact, staying active can improve symptoms. If symptoms persist or are disabling, pharmacologic treatments such as dopamine agonists or anticonvulsants may be considered later on.
