We all know sleep to be important, but what makes it so vital? Other than hormonal responses, what physical affects are gained through sleep? I'd like to compartmentalize the mental effects from the physical effects. I'd like to define mental primarily with the brain chemicals involved with sleep. Is it safe to say that most of the physical benefits of sleep such as growth hormone release, cortisol, etc come from the brain and its functions?
So from this, can we conclude that the only thing that needs sleep are our brains?
But mainly, how does the brain "rest"?
The above link is on sleep dep studies. Not exactly what I'm looking for, but interesting none the less.
