                                According to the Centers for Disease Control and Prevention (CDC), healthy adult kidneys can only eliminate about 0.8 to 1.0 liters of water per hour. Attempting to drink 3 water bottles in an hour, which often exceeds this processing rate, can overwhelm the body's systems and lead to dangerous complications like hyponatremia, where blood sodium levels become critically low.
