Environmental Triggers


Certain trigger factors can be related to environmental issues such as dust, smoke, high altitude, weather changes, heat, humidity, loud noises, strong smells, exposure to glare or flickering lights. Sitting in front of a computer at home or work for long periods of time can cause problems if you experience migraine.

The simple rules OH&S recommends for everyone, such as taking regular breaks, using anti-glare screens and good lighting, can help avoid migraine attacks. Sitting comfortably is very important when you use a computer to avoid muscle tension building up in the head, neck and shoulders, which can trigger some people, so make sure your workstation is properly set up. Migraine is an invisible disability, so you can ask for reasonable adjustments in your workplace, such as a glare filter on your monitor or moving your desk. Hence, a light that is bothering you is not in your eye line.

Exercise helps prevent migraine, but for about a third of people living with migraine, exercise is also a trigger. The best theory is that the sudden increase in cardiac activity causes a spasm in blood vessels in the brain, which is one of the things that can start an attack. Beta-blockers can be an effective preventative for people with exercise-induced migraine.

If you live with exercise-induced migraine, you probably did not have much difficulty identifying this trigger. However, you don’t have to avoid exercise entirely. Here are some tips to help you to exercise without triggering an attack:

  • Avoid high impact activity or anything that needs a great or sudden burst of physical exertion.
  • Do long warm-ups and cooldowns to smooth the cardiac activity.
  • Consider smoother sports, like yoga and swimming, over higher intensity sports like boxing or football.
  • Stay well hydrated and, if possible cool – exercising indoors in an airconditioned environment may be best.
