Researchers from several prominent universities examined the self-reported sleep habits of nearly 130,000 teens. They found that the number of teens getting insufficient sleep, defined as seven hours or less a night, rose from 69% in 2007 to 78% in 2023, the most recent year for which data was available.
“We know that sleep plays a really critical role in adolescent brain development,” said Tanner Bommersbach, a child and adolescent psychiatrist and assistant professor of psychiatry at the University of Wisconsin-Madison and one of the authors of the study. “So when large numbers of teens aren’t getting enough sleep, it really raises concerns about the downstream effects that that could be having on their mental health, on their academic performance, on their engagement and risk behaviors.”
