Circadian Rhythm

Circadian rhythm enters the wiki through The Parents’ Guide to Boys by Abigail Norfleet James, which flags that “adolescents identified with circadian rhythm problems are a growing issue in middle and high schools today.” In the book’s context this sits among its arguments about how boys’ development and biology collide with school structures — a sleep-and-schedule mismatch that affects teen learning and behavior. It is a single-line mention rather than a developed thesis, so this page stays a thin stub keyed to that one source.

Context: The circadian rhythm is the body’s roughly 24-hour internal clock, governing sleep-wake cycles, hormone release, and alertness. Adolescents experience a well-documented biological shift toward later sleep and wake times — the basis for the school-start-time debate in education.
