                                Research has shown that even mild dehydration, a 1-2% loss of body fluid, can negatively impact brain function. But beyond functional changes, can dehydration temporarily cause your brain to shrink? The answer, supported by scientific studies, is yes, and this article will explore the mechanisms behind this surprising effect.
