A closer look
Overhydration, also known as water intoxication, occurs when excessive liquid consumption dilutes the sodium levels in your bloodstream, leading to a potentially fatal condition called hyponatremia where brain cells rapidly swell with fluid. The fitness industry spends billions convincing you to carry around a massive, brightly colored plastic jug to constantly sip from, inadvertently pushing people closer to a watery grave in the name of optimum cellular hydration. We are carbon-based lifeforms that desperately need water to survive every metabolic process, yet if you become too enthusiastic about quenching your thirst, your body will simply short-circuit and shut down completely. Moderation is literally the only thing keeping your heavily hydrated brain from exploding inside your skull
