Abstract
You’ve probably experienced it – your alarm is set for 6:30am, yet somehow your eyes snap open a few minutes before it goes off. There’s no sound, no external cue, just the body somehow knowing it’s time.
It might seem strange, but you didn’t wake up by chance. It’s your body clock at work – an amazingly precise internal timing system that regulates when you sleep and wake.
But how exactly does this built-in alarm clock work?
