The alarm clock rings, the brain sleeps

Description

Many children and adolescents often sit in the classroom during the first hours of lessons looking exhausted and are hardly receptive. The reason is not discipline but biology: During adolescence, their biological clock shifts backwards. A new study by the University of Zurich and the Zurich Children's Hospital now shows: When school starts later or more flexibly, teenagers sleep significantly more, are healthier – and also achieve better learning outcomes. What does sleep biology say about the optimal start of lessons? And what can schools, parents, and policymakers learn from this?
