…och inte tio minuter eller två timmar? På Answers.com ges en intressant djupdykning i ämnet. Där fastslås tre olika teorier och bidragande faktorer till de nio mytomspunna minuterna vi otacksamt besudlar med våra okynnessömn.
Teori 1 - Den digital snoozen
Well, I have researched this topic and yielded some theories. If the snooze button is 9 minutes then the digital clock would only have to keep track of the last digit, because the last digit would go down by 1.
Teori 2 - Den analog snoozen
By the time the snooze feature was added in the 1950’s, the innards of alarm clocks had long been standardized. This meant that the teeth on the snooze gear had to mesh with the existing gear configuration, leaving engineers with a single choice: They could set the snooze for either a little more than nine minutes, or a little more than 10 minutes.
But because reports indicated that 10 minutes was too long, allowing people to fall back into a “deep” sleep, clock makers decided on the 9-minute gear, believing people would wake up easier and happier after a shorter snooze. We’d tend to disagree with that logic, but, then, we must be in the lazy minority. Although today’s digital clocks can be programmed to have a snooze of any length, most stick with nine minutes because that’s what consumers expect.

Teori 3 - Den matematiska snoozen
Some alarms shut off after a period, such as cell phone alarms; the alarm is 1 full minute, and then 9 minutes of snooze. The whole process takes 10 minutes.
