Hydration for Brain Power

Hydration for Brain Power

When asked about hydration and brain health, Dr. Sanjay Gupta says, "We often mistake thirst for hunger. Even moderate amounts of dehydration can sap your energy and your brain rhythm."

Several studies have shown reduced cognitive function in dehydration and the Importance of staying hydrated to preserve (or even at times) enhance cognitive function.

  • The brain, compared to the rest of the body contains more water mass, approximately 75% of all brain mass is water.
  • Water is required to provide metabolic and structural support for cells & tissues, & is involved in the transport of essential nutrients & compounds: essential for proper neuronal function!
  • Even mild dehydration (around 4 cups or less per day) is associated with reduced cognitive function (increased fatigue, sleepiness & attention.)
  • To keep hydrated, it’s recommended that women consume 2 to 2.7 liters (8 to 11 cups) and men consume 2.5 to 3.7 liters (10 to 15 cups) of fluids per day. (This can vary based on activity level & other factors!)
