Later start time has positive impacts in schools
Delaying an adolescent’s school start time by one hour has a positive effect on his or her cognitive performance, according to a research abstract presented at Sleep 2008, the 22nd Annual Meeting of the Associated Professional Sleep Societies (APSS).
The study, authored by Orna Tzischinsky, PhD, of Emek Yezreel College in Israel, focused on 47 eighth graders from two classes, who were divided into experimental and control groups for a two-week period. On week one, the experimental class began their school day one hour later than usual 8:30 a.m. start time. The control class, however, started right on time, as far as the school district was concerned: promptly at 7:30 a.m. On week two, both classes began at 7:30 a.m.
