While federal guidelines recommend 9.25 hours of sleep each night for students, that could be too much for teens, concludes a new study, which correlated students’ hours of sleep to reading and math scores.
The study found the optimal sleep amount for 10-year-olds ranges between 9 and 9.5 hours, while for 18-year-olds it is slightly less than 7 hours. At ages 12 and 16, children need between 8.34 to 8.43 hours and 7.02 to 7.35 hours, respectively, the study found.
It’s possible too much sleep may reduce academic achievement, the authors speculated. I can’t believe many kids are getting too much sleep as school start times move earlier and earlier.
