Drink Up: Why Hydration is Key for Mental Clarity | The Ultimate Human | Ep. 80

Impact on Brain

Gary Brecka highlights the profound impact dehydration has on the brain, emphasizing its role in reducing brain volume and slowing neural activity. This reduction in brain volume occurs as brain cells lose water, leading to impaired cognitive function and slower information processing 1. Dehydration also elevates cortisol levels, the body's primary stress hormone, which can further impair memory and cognitive functions.

Dehydration impacts the brain in several ways. Number one, reduced brain volume. According to research from the Journal of American College of Nutrition, dehydration causes brain cells to lose water, and this leads to reduced brain volume and impaired cognitive function.
