                                According to the Mayo Clinic, a healthy adult's kidneys can filter and excrete roughly 0.8 to 1.0 liters (about 34 ounces) of water per hour. Drinking 2.5 gallons (10 liters) of water daily is a dangerously high intake that can overwhelm the body's systems, leading to severe health complications.
