Abstract

Background: In recent years, growing attention has been directed toward understanding how lifestyle factors influence student well-being and academic performance. Increased academic pressure, late-night study habits, and online learning have led to widespread sleep deprivation. Simultaneously, dietary habits have worsened due to fast-food consumption. These patterns have raised concerns about cognitive fatigue and health issues. This study explores how sleep duration and nutritional quality together affect students’ health, using long-term trend data to identify patterns and possible interventions. Methods: A longitudinal dataset from 2000 to 2024 was compiled using secondary data sources. It includes average sleep duration, nutritional quality index, cognitive fatigue scores, and health complaints. Descriptive statistics, trend analysis, and correlation assessment were used to explore associations between lifestyle factors and cognitive or health outcomes. Results: Between 2000 and 2024, average sleep duration among students declined from 7.4 to 5.8 hours per night, reflecting a 21.6% decrease. The nutritional quality index fell from 78 to 62, indicating a significant drop in healthy eating habits. Cognitive fatigue scores increased by more than 40%, reaching 42 in 2024, while reported health complaints such as poor concentration, and persistent tiredness more than tripled, especially after 2015. Conclusion: Students are facing increased cognitive fatigue and health challenges despite academic progress. Therefore, promoting nutrition awareness, enhancing wellness programs, and supporting mental health, AI-driven health monitoring and continued research are vital for protecting student well-being and academic performance.
