Why do my legs feel restless at night?
Last updated September 3, 2026.
An urge to move your legs the moment you rest - with creeping, crawling, or tingling that moving relieves - is restless legs syndrome, a real condition the NHS links to iron and the brain chemical dopamine. Caffeine after midday and evening alcohol feed it; an iron check is worth having. Pymander is a free AI doctor, 24/7 by text, and can help you review your evenings.
What to do
- No caffeine after midday, and no alcohol within 2 hours of bed.
- Keep evenings light: no big meals, hard workouts, or doom-scrolling right before sleep.
- Ask a GP about an iron test - low iron is a treatable driver.
- Self-help failing or sleep wrecked? See a GP - effective medicines exist.
