Lifestyle
Hydration
for Brain Fog
Drinking adequate water throughout the day — even mild dehydration of 1–2% body weight impairs cognitive performance measurably.
How it works
The brain is 75% water. Even mild dehydration reduces cerebral blood flow, slows neural transmission and impairs attention, short-term memory and psychomotor speed.
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.
