CNN reports on a study showing that sleeping children awoke to recordings of their mothers' voices more quickly and more often than to a beeping smoke alarm.
The study of 24 children ages 6 to 12 found that 23 awoke to the recorded voice of their mother saying "(Child's first name)! (Child's first name)! Wake up! Get out of bed! Leave the room!" Fourteen of the children also awoke to the traditional tone alarm. One child didn't wake up to either.
The children who woke up to the voice did so at a median time of 20 seconds, compared with three minutes for those who woke up to the tone, according to the study by Columbus Children's Hospital researchers being released Monday in Pediatrics.
