Today’s Video of the Day from the University of Washington describes the sleep benefits of starting school later in the morning.
In 2016, the Seattle school system delayed the start time of secondary schools by 55 minutes.
Researchers equipped students at two of the high schools with activity trackers in order to precisely document when the teenagers were sleeping.
According to study co-author Professor Horacio De La Iglesia, it is biologically difficult for teenagers to fall asleep at bedtimes that would allow for a sufficient amount of sleep.
The experts found that the students were not falling asleep any earlier, but were resting longer in the mornings, which increased their sleep by an average of 35 minutes.
The study also revealed that the teenagers became more alert and showed significant improvement in their overall grades and school attendance.
The research is published in the journal Science.
