How does sleep affect exam performance?

Sleep plays a crucial role in cognitive functioning, which directly impacts exam performance. When a person is well-rested, their brain is better equipped to focus, think critically, and retain information, all of which are essential for performing well on exams. Quality sleep contributes to improved memory consolidation, meaning that what a person learns and studies is more likely to be recalled during an assessment.

Inadequate sleep can lead to a decline in attention span and slower reaction times, which can hinder performance during exams. It also affects decision-making abilities and problem-solving skills, as fatigue can impair the brain's ability to process information efficiently.

Thus, maintaining good sleep hygiene is vital for optimal cognitive function and overall academic success.
