I'll spend a third of my life in bed with the lights out. But why is a good night's sleep so important to me?

Scientists who studied the brain of a sleeping mouse with a microscope saw new connections forming between brain cells important for memory. Sleep disruption prevented the new connections from forming. No wonder my brain feels so fuzzy when I get up early. All the more reason to make sure I get a full eight hours each night!

This research was published in the 6 June 2014 issue of the journal Science.
