A new study found that early-morning classes are associated with “lower attendance, shorter sleep, and poorer academic achievement” among college students.
The study, published Monday in Nature Human Behavior, analyzed university students’ digital traces. Wi-Fi connection logs of 23,391 students revealed that class attendance was about 10 percentage points lower for classes at 8 a.m. compared with later start times, according to the study.
The study also analyzed the grades of 33,818 students and the number of days per week that a student had morning classes and found that morning classes negatively correlated with their grade point average.
“Growing evidence indicates that early class start times can be detrimental for students’ sleep and daytime functioning,” the study says.
A similar study published last week in Proceedings of the National Academy of Sciences found that every additional hour of average nightly sleep early in the semester is associated with an 0.07-point increase in end-of-term grade point average.
