SLEEP, BRAIN FUNCTION, AND ACADEMIC PERFORMANCE

Abstract

Sleep is a fundamental biological process essential for optimal brain functioning and effective learning. Increasing evidence indicates that insufficient or poor-quality sleep adversely affects cognitive processes critical for academic performance, including attention, memory consolidation, executive functioning, and emotional regulation. This chapter examines the physiological architecture of sleep and the neurobiological mechanisms underlying its regulation, with particular emphasis on how sleep supports brain plasticity and cognitive efficiency. It further explores typical sleep patterns among students and the behavioural, social, and technological factors contributing to chronic sleep deprivation in academic populations. Empirical evidence linking sleep duration and quality to academic outcomes such as grades, learning capacity, and cognitive performance is reviewed. The chapter also discusses experimental and intervention studies that highlight the causal role of sleep in learning and memory. Finally, practical implications for educational policy and student well-being are considered, underscoring the importance of sleep promotion as a strategy to enhance academic performance and cognitive health.
