The idiom uses the letter 'Z' to represent the sound of snoring, which is commonly associated with sleeping. Originating from comic books where 'Z' was often used in speech bubbles to indicate that a character is sleeping, this expression conveys the idea of resting your eyes and recharging through sleep.
