What is the estimated maximum hourly rate at which a healthy adult kidney can process water?
Answer
0.8 to 1.0 liters per hour
The kidneys have a finite capacity to process and excrete water, estimated at 0.8 to 1.0 liters per hour in healthy adults. Consuming fluids significantly faster than this rate forces the body to cope with an excess volume that cannot be expelled immediately, which increases the risk of water intoxication and sodium imbalance.
