Water consumption and brain function are integrally connected. Over 60% of the adult human body is composed of water and every system in the body is dependent on proper hydration, including the activities of the brain and nervous system.
“Brain cells require a delicate balance between water and various elements to operate,” says University of Texas neuroscientist Joshua Gowin. “When you lose too much water, that balance is disrupted. Your brain cells lose efficiency.” Research has demonstrated that lack of water to the brain can impair short-term memory function and the recall of long-term memory, as well as cause a variety of symptoms such as brain fog, exhaustion, headaches, sleep issues, stress, anger, and depression.
