Hydration
for Migraine
Maintaining adequate daily fluid intake. Dehydration is a well-recognised migraine trigger. Simple and risk-free preventive measure. Aim for consistent daily intake rather than catching up after dehydration occurs.
How it works
Dehydration causes changes in plasma osmolality that may trigger cortical spreading depression — the neurological event underlying migraine. It also affects cerebral blood flow and increases pain sensitivity.
What to watch for
Consistent daily intake is more effective than trying to rehydrate once symptoms start. Caffeinated drinks count toward fluid intake in moderation but can be triggers for some people.
