If you spend hours a day on the computer, try looking at your monitor when it's off to see if there's any light reflected on it from windows or light fixtures. "[These reflections] may not be evident when the screen is on, but nonetheless may produce glare, which may potentially trigger migraine," Dr. Krauss told POPSUGAR. If you can adjust the position of you screen to reduce glare, do it.
Dr. Bashir also stressed the importance of making sure your monitor is at eye level, which will encourage proper posture. Bad posture can lead to neck and shoulder pain, which in turn can contribute to headaches.
