Combating lethargy requires addressing lifestyle, medical, and psychological contributors. Prioritize consistent sleep schedules, aiming for 7–9 hours nightly, and maintain balanced nutrition with adequate protein, iron, and complex carbohydrates. Regular physical activity improves circulation and energy regulation, even when limited to light daily movement. Manage stress through structured breaks, mindfulness, or cognitive techniques. Stay hydrated and moderate caffeine to avoid energy crashes. If lethargy persists, evaluate underlying causes such as anemia, thyroid dysfunction, depression, or parasitic infections sometimes treated with medications like mebendazole 500mg under medical supervision. Persistent fatigue warrants professional clinical assessment and targeted intervention.
