Cognitive Performance and Sleep

Meaning

Cognitive Performance and Sleep describes the critical, reciprocal relationship where the quality and adequate duration of sleep are the foundational requirements for optimal executive function, memory consolidation, and sustained attention during wakefulness. Clinically, insufficient or fragmented sleep is recognized as a significant, modifiable factor that directly impairs daytime neurocognitive function and emotional regulation. Optimal sleep is therefore viewed as the necessary physiological substrate for robust and sustained mental acuity.
