Hygienic Factors Influencing Cognitive Performance and Mental Health Among University Students: A Survey-Based Analysis in The Context of Sanitary Standards of Uzbekistan
Keywords:
cognitive efficiency, educational hygiene, university students, mental health, psycho-hygiene, sleep quality, academic stressAbstract
This study evaluated hygienic factors affecting cognitive performance and mental functioning among university students in Uzbekistan. A cross-sectional survey involving 420 students of the Fergana Medical Institute of Public Health was conducted during the 2026 academic year. The study assessed sleep quality, psycho-emotional stress, digital exposure, physical activity, nutritional habits, and educational environmental conditions. The findings demonstrated that irregular sleep schedules, prolonged screen time, chronic academic stress, insufficient physical activity, and unhealthy nutritional behavior were associated with decreased concentration, memory difficulties, emotional instability, and mental fatigue. Students reporting poor sleep quality and excessive smartphone use demonstrated significantly higher prevalence of headaches, visual strain, and reduced learning productivity. The results indicate that educational hygiene and lifestyle factors substantially influence cognitive efficiency and mental health among university students.
