Certain trigger factors can be related to environmental issues such as dust, smoke, high altitude, weather changes, heat, humidity, loud noises, strong smells, and 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.
