How does sleep deprivation affect cognitive performance?

Sleep deprivation significantly impairs various aspects of cognitive performance, with attention and decision-making being some of the most affected areas. When an individual does not get enough sleep, their brain struggles to function optimally, leading to difficulties in focusing on tasks and processing information accurately. This can result in slower reaction times and increased errors in judgment.

Cognitive functions such as memory consolidation, processing speed, and executive functions are all compromised due to a lack of sufficient restful sleep. Research has shown that chronic sleep deprivation can lead to declines in performance that mimic the effects of alcohol intoxication. This underscores the importance of adequate sleep not just for physical health, but for maintaining vital cognitive abilities that are essential in daily decision-making and tasks requiring attention.
