Sleep Patterns Are Linked to Academic Success

Prof. Ana Allen Gomes

Several experimental studies point to associations between sleep and performance of various cognitive activities that are intuitively linked to academic achievement.  These include, for example, learning and memory consolidation.  Accordingly, sleep restriction, poor quality of sleep, and late and irregular sleep schedules are expected to have an adverse effect on academic performance.  Yet, very few studies assess the effects of sleep patterns on scholastic achievement by taking into consideration multiple potential predictors of academic outcomes.  The present study took advantage of a university setting to analyze associations between sleep patterns and multiple measures of academic success and to determine which sleep patterns may serve as significant predictors of academic performance.  Sleep phase, morning/evening preference, sleep deprivation, sleep quality and sleep irregularity were all found to be significantly associated with scholastic performance measures.  Quantity and quality of sleep also emerged as significant predictors of the end-of-semester grades.
