When you are dehydrated, your brain tissue can actually shrink away from the skull slightly, putting physical pressure on the sensitive meninges. This stress triggers the trigeminal nerve and initiates a migraine in sensitive individuals.
Drinking pure water isn't always enough. The migrainous brain requires stable levels of Magnesium, Sodium, and Potassium. Rapid fluid loss through exercise, humidity, or illness is a guaranteed trigger.
Track your water intake alongside your attack history — you may find that your worst migraine days correlate with high-activity days without sufficient hydration.
The Relief app correlates your attacks with weather, sleep, food, and more — automatically.
