Can Dehydration Make You Crazy?

Not without an underlying mental illness. Lack of sleep, water, and food can all impair your thinking, but their effects are usually more mundane. Dehydration is the quickest to take its toll, with symptoms appearing in a matter of hours or days. Mild dehydration might give you a headache, slow your reaction time, and hurt your performance on cognitive tests, perhaps because it leads to an electrolyte imbalance in the brain. Extreme dehydration can cause irritability, disorientation, and even delirium. It can also, of course, kill you. Whether death by dehydration is torturous or serene is a matter of debate. But it usually doesn?t involve sexualized outbursts in public.
