In comparison, three minutes is NOT enough. For some reason, my wife has her snooze set for 3 minutes, and then continues to sleep through several three minute snooze segments. In three minutes, the body doesn't have a chance to really get back to sleep. Just as the body gets comfortable again – there it is: “WAKE UP, WAKE UP, WAKE UP!” When I asked her, in an era where we can set the length of our snooze intervals, why did she choose three minutes? Her response: “because that’s the way it was set when I got it.” Three minutes is definitely not enough.
