Mismatch between social versus biological clocks in the teenage years compromise performance: first insights on molecular mechanism

A growing body of literature has linked chronotype and sleep to school performance. Chronotype is under the control of the circadian clock and refers to sleep timing and diurnal preferences. Chronotype changes over the lifespan and is latest during adolescence (evening preference), giving rise to a mismatch between the (late) circadian clock and the (early) school clock. In general, evening (late) chronotypes obtain lower grades and show high rates of absenteeism. School performance is influenced by many other factors, such as motivation, intelligence, and conscientiousness. Some of these factors also relate to chronotype. The talk will discuss the relationship between chronotype and school performance including the possible molecular mechanisms involved.
