Background: Sleep deprivation is a growing concern among adolescents due to increased academic demands, excessive screen time, and lifestyle changes. Insufficient sleep has been associated with impaired cognitive functioning and reduced academic performance.
Objective: This study aimed to examine the effects of sleep deprivation on cognitive performance and academic achievement levels among adolescents.
Methodology: A quantitative cross-sectional study was conducted among 250 adolescents aged 13–18 years from secondary schools. Data were collected using a structured sleep assessment questionnaire, cognitive performance tests measuring attention, memory, and problem-solving abilities, and academic records. Descriptive statistics, correlation analysis, and regression analysis were used to evaluate relationships among variables.
Findings: Results indicated that 68% of participants experienced sleep deprivation, defined as sleeping less than 8 hours per night. Sleep-deprived adolescents demonstrated significantly lower cognitive performance scores (Mean = 72.4 ± 8.6) compared to those with adequate sleep (Mean = 84.7 ± 7.9; p < 0.001). Academic achievement levels were also lower among sleep-deprived students (Mean GPA = 2.89 ± 0.51) than their peers (Mean GPA = 3.45 ± 0.47; p < 0.001).
Conclusion: Sleep deprivation negatively affects adolescents’ cognitive performance and academic achievement. Promoting healthy sleep habits may enhance learning outcomes and overall educational success.
