I was taken aback when an elderly patient confessed dejectedly that she didn't drink the eight glasses of water her physician had prescribed. I was astounded to learn that water loading for all comers pervades medical practice. But how robust is the scientific evidence and how did this come about?

Yet I could not recall a single scientific study on the benefits of increased water consumption.
