Hydration
for Brain Fog
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
Coffee and tea contribute to fluid intake but their diuretic effect means plain water should make up the majority of daily fluid. Dark urine indicates inadequate hydration.
