Purpose of Review

Most adolescents experience circadian misalignment due to a mismatch between their delayed circadian physiology and early school start times. This review considers cognitive functioning and school behaviors, associated with delayed circadian timing and subsequent circadian misalignment. Insights from special populations and lessons learned during the COVID-19 pandemic are also highlighted.

Recent Findings

When adolescents experience circadian misalignment, there are implications for their cognitive functioning and school behaviors. Findings emphasize the need to align school start times with adolescents’ delayed circadian physiology to provide more conducive learning environments. Indeed, adaptations in learning schedules during the COVID-19 pandemic may have benefited adolescents’ sleep. Ultimately, adolescents who experience greater circadian misalignment and those that have later sleep preferences are most vulnerable to cognitive and school-related difficulties.

Summary

Establishing later school schedules or developing individualized strategies to shift the circadian system earlier could help improve cognitive functioning and school behaviors at a critical time in youth’s development.
