For those of yo u who are the snooze button advocates I found an article. Make of it what you will.

" In a nation that clocks six to seven hours of sleep a night when an average of eight hours is recommened, it is a rare person who wakes up without an alarm. And because it is usually a struggle, pushing "snooze" to delay the day has become as much of a part of the wake up ritiual as a cup of coffee.
But is a bumpy arousal for 30 60 or even 90 minutes a way to recoup much needed sleep? Or is it a recipe for exhaustion?
Although scientist have not spesifically tackled the question, sleep researchers agree that short spurts of sleep are far from ideal. The restorative value of rest is dimnished, especially when increments are short, said Dr. Edward Stepanski, whoo has studied sleep fragmentation. And a teeter totter effect of dozing and waking causes shifts in brain wave patterns."
"Even a subtle noise that doesn't actually wake you up is disruptive enough to affect sleep quality," Stepanski said. "That's why someone who falls asleep with the TV on may wake upexhausted. So if a person is rousing themselves enough to reset a clck, ther's likly to be an even more profound effect."
