If there is a "the reason" we sleep, it's that our evolutionary linage has left us that way. The "functions" of sleep, which involve an entirely different set of questions and concerns, appear to be numerous and varied. Most of them seem related to learning, memory, and tissue repair.

Sleep seems to perform a lot of important functions for us. I think it's also worth mentioning that the need for sleep creates significant, sometimes fatal vulnerabilities.
