ABSTRACT: The relationship between sleep quality and cognitive function is a critical area of research in health and behavioral sciences, with direct implications for individual wellbeing and societal efficiency. This study investigates how variations in sleep quality influence daily cognitive performance, particularly in areas such as attention, memory, processing speed, and emotional regulation. Employing a mixed-methods approach, the research integrates self-reported sleep assessments, standardized cognitive performance tests, and physiological data collected via wearable monitoring devices. The findings indicate that poor sleep quality is consistently linked to diminished cognitive abilities, including reduced attention span, impaired memory consolidation, and increased emotional instability. Additionally, both intrinsic factors (such as age, health status, and circadian rhythms) and extrinsic factors (including noise exposure, artificial lighting, and screen time) significantly impact sleep patterns. This study emphasizes the urgency of implementing effective interventions—ranging from sleep hygiene practices to mindfulness techniques—to enhance sleep quality. The results underline the importance of public education and policy support in addressing widespread sleep disturbances and their long-term cognitive consequences. Ultimately, this research contributes to the growing evidence that prioritizing healthy sleep is essential for cognitive resilience and overall quality of life in today’s fast-paced environment.
