                                According to medical experts, the kidneys of a healthy adult can only process and excrete roughly 0.8 to 1.0 liters of water per hour. Pushing past this threshold by drinking more than 1 liter of water an hour can rapidly overwhelm the body's natural regulatory systems and trigger a cascade of dangerous health complications.
