A survey conducted at a high school in suburban Philadelphia, conducted by a team comprised of one of the school’s students and her father, a sleep specialist, to learn what sleep-deprived teens thought of starting school days later in the morning, as well as having tests given later in the school day which may result in better grades. The survey’s findings was presented at the American Thoracic Society 2007 International Conference, on May 20, 2007.
The survey of 280 high school students confirmed what most parents with a teenager know: the students are not getting enough sleep. More sleep would translate into improved academic performance, according to the teens questioned. They all attended Harriton High School in suburban Philadelphia, where the school day begins at 7:30 a.m. and ends at 2:25 p.m.

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.

In healthy people, both sleepiness and vigilance show a relationship with core body temperature and skin temperature. When core body temperature is high during the daytime, skin temperature is low, which translates into optimal vigilance.
Researchers noted during a recent study, though, that when core body temperature is low at night time, skin temperature is high, which correlates to optimal sleep. Among those suffering from narcolepsy, however, direct manipulations of their skin and core body temperatures affect their vigilance and sleepiness.
