About migraine triggers:

People who suffer from migraine are often encouraged to think about potential ‘triggers’ for their migraine and try to make lifestyle changes. Migraines can be triggered or aggravated by many factors, including:

  • Weather (e.g., temperature change, high humidity)
  • Diet (e.g., chocolate, aged cheese, caffeine, alcohol)
  • Surroundings (e.g., bright lights, strong odours, loud sounds)
  • Hormones (e.g., menstruation, birth control pills)
  • Physical factors (e.g., strenuous exercise like aerobics, poor quality of sleep)
  • Stress (e.g., anxiety, worry)

Lifestyle changes including relaxation and exercise may also be effective in treating and preventing migraine.
