Why do early mornings feel so brutal for teens? In this episode, we explore the science behind teenage sleep and circadian rhythms and why early school start times may be setting students up for failure.

We talk to students from Italy and Germany, and sleep researcher Dr. Anna Magdalena Biller, to understand how biology, not laziness, is behind teen sleep struggles — and what schools, parents, and teachers could do about it.

Big thanks to Margha, Lea, Giulia, Alice and Viola for sharing their perspectives on school start times!
