About this trial
The goal of this clinical trial is to determine whether a combination of a novel lighting intervention and a behavioral intervention are able to increase total sleep time in adolescents. The main questions this trial aims to answer are whether this combination therapy is able to meaningfully increase total sleep time in adolescents, and do so over a sustained period of time, and whether such a changes is associated with concomitant changes in mood and cognitive performance.
