About the Study

Adolescence, especially age 12 - 15, is associated with a change in the internal body clock, leading to later bed and wake times. This natural shift makes many teenagers prefer going to bed late at night, and to wake late in the morning. However, school starts early, and many teenagers do not get enough sleep during school nights. Insufficient sleep could affect teens’ mood and thinking.  In this study we are interested in how the changes in sleep, body clock, and light may influence mood, and thinking over time, including changes in NAPLAN scores from Year 7 to Year 9.
The Circadian Light in Adolescence, Sleep, and School (CLASS) Study is a longitudinal study  funded by the Australian Research Council (ARC). We aim to investigate the relationships between the circadian clock, sleep and light interactions in adolescent cognitive function and how they change over time. This research study is conducted by researchers in the Turner Institute for Brain and Mental Health at Monash University, in collaboration with leading international experts.​
