STUDY Adequate rest helps high school students fare better
High school students seem to do better in studies when they have seven hours of sleep, rather than nine recommended by federal guidelines, a study reveals.
“We're not talking about sleep deprivation, the data simply says that seven hours is optimal at that age,” said study co-author Eric Eide from Brigham Young University (BYU), USA. The new study, is the first in a series where they examine sleep and its impact on our health and education. Surprisingly, the current guidelines are based on studies where teens were simply told to keep sleeping until they felt satisfied, said a university statement. Eric's co-author, Mark Showalter adds, “Somehow that doesn't seem right.”
Analysing data from a representative sample of 1,724 primary and secondary school students across the country, they found a strong relationship between the hours of sleep youths got and how they fared on standardised tests. From the other end, if a kid is only getting 5.5 hours of sleep a night because he's overscheduled, he would perform better if he got 90 minutes more each night,” Eide said.
An 80-minute shift toward the optimum is comparable to the child's parents completing about one more year of schooling.
