High School Start Time and Migraine Frequency in High School Students.

High school start time does not have a large effect on headache frequency in high schoolers with migraine. Given the high variance in headache days/month observed in this study, a larger study would be needed to determine whether there might still be a small effect of starting high school at/after 8:30 AM. More research is needed to establish evidence-based recommendations about lifestyle factors in adolescent migraine management.
