Screens and sleep: beyond blue lightAlmost all adults consult a medium at least once in the hour before bedtime, according to a study by a UdeM doctoral student. What impact does this have on their sleep? "I wanted to explore media use by a diverse population and its association with sleep variables," sums up Ajar Diushekeeva, a doctoral student in Research and Intervention, Clinical Psychology option, at the Université de Montréal, under the supervision of Antonio Zadra (Department of Psychology) and Santiago Hidalgo (Department of Art History, Cinema and Audiovisual Media).
