A study (ID# 1118) from Israel that is being presented as an oral presentation this morning at SLEEP 2008 shows that teens may have improved attention and concentration when their school start time is delayed.
The study involved 47 eighth-grade students from two classes. A control group began school at the regular time (7:30 a.m.) each day for two weeks. The experimental group began the schoolday one hour later (8:30 a.m.) during week one and then at the usual time during week two.
During the first week, students in the experimental group woke up an average of 51 minutes later each morning than students in the control group. Bedtime remained the same.
The experimental group performed better than the control group on two cognitive tests that were performed on the fifth day of the first week. They had a better overall attention score on a computerized test and made fewer mistakes on a paper-and-pencil test.
According to the American Academy of Sleep Medicine, teens need a little more than nine hours of sleep each night to be alert the next day.

Research Abstracts Examine the Effect of Sleep on School Performance
Research abstracts being presented as poster presentations this morning at SLEEP 2008 are describing the link between sleep and school performance.
One study (ID# 0199) found that different sleep variables affect the school performance of students in junior high, high school and college. In junior high, the complaint of restless legs/aching legs is more common in students with a lower grade-point average (GPA). Daytime sleepiness is more likely to affect the performance of high school students. Insomnia has the most negative effect on the GPA of college students.
A related study of adult college students (ID# 0709) found that insomnia complaints are significantly associated with lower GPAs. Students with lower GPAs were more likely to have trouble falling asleep, report waking at night and have trouble going back to sleep.
A study of 824 undergraduate students (ID# 0728) found that students who are “morning types” (preferring to wake up early) are more likely to have better grades than students who are “evening types” (preferring to stay up late).
