Regular Aerobic Exercise 🤩

Regular aerobic exercise, such as brisk walking, cycling, or swimming, has consistently been shown to reduce migraine frequency, duration, and intensity. In head to head trials, its effectiveness matches or exceeds preventative medications.

🧠 Biological Plausibility

Aerobic activity improves metabolic health and reduces systemic inflammation through a variety of mechanisms. It directly enhances mitochondrial functdion.

🔬 Evidence

Numerous randomized controlled trials and meta-analyses support aerobic exercise as one of the most effective non-pharmacologic migraine preventives. A 2022 network meta-analysis found it reduced migraine days by 2–3 per month, with an effect comparable to topiramate and greater than several supplements. Adherence and gradual progression are key to achieving benefit.

🎯 Effect Size

Moderate to large. Studies consistently show a 30–50% reduction in monthly migraine frequency with 3 or more sessions per week. Benefits extend to mood, sleep, and energy regulation.

⚠️ Risk

Low.

🔍 Clinical Takeaways

  • One of the strongest evidence-based non-drug migraine preventives
  • Best results occur with consistent, moderate-intensity exercise (e.g., brisk walking, cycling, swimming)
  • Exercise improves nearly every system contributing to migraine vulnerability—making it foundational for long-term brain and metabolic health
