Migraines are a form of severe headache, often accompanied by nausea, dizziness, and heightened sensitivities to light, sound, and other sensory input.

In this article, air quality experts from Camfil explain how air pollution affects migraine sufferers and what you can do to prevent severe migraine episodes from occurring.
