SEATTLE (UPI) -- High-quality sleep is correlated with better grades,
especially math, but sleeping late on the weekend is linked to worse
grades, U.S. researcher said.
The study found that higher math scores were related to greater sleep
quality, less awakenings and increased sleep efficiency, but higher
English and history scores were associated with less difficulty
awakening.
Principal investigator Jennifer C. Cousins, a postdoctoral fellow at
the University of Pittsburgh Medical Center, said the results were
surprising.
"Sleep deficits cause problems for adolescents, but students differ in
their personal resources and in how chaotic their sleep-wake schedules
are," Cousins said in a statement.
"The more regular and predictable their sleep is, the better they are
likely to do when confronted with short-term sleep deficits.
Therefore, participants with better sleep overall may be affected
differently in a sleep condition compared to those who have a more
varying sleep/wake schedule."
The study involved data from 56 adolescents -- 34 female -- between
the ages of 14-18 years who had complaints of daytime sleepiness and
or insufficient sleep at night. Participants reported their grades and
overall academic standing.
The findings were presneted at Sleep, the 23rd annual meeting of the
Associated Professional Sleep Societies in Seattle.
