Summari Article #1

A recent study shows that when schools start one hour later, students increased their hours of sleep, and decreased their catch up sleep in the weekends. This created fewer automobilistic accidents with students. The percentage of students who got at least eight hours of sleep per weeknight increased from 35.7 % to 50%. Students who got at least nine hours of sleep also increased from 6.3 % to 10.8 %. There were many more crashes prior to the change in class start time.
