Smartphone Addiction and its Impact on Health among High School Students

Smartphone addiction has been increasing among high school students, which influences physical health, psychological health, academic performance, and social life. To address this problem, this study explores smartphone addiction among students in a structured research framework based on empirical data. A quantitative research design was used in this study, and data were obtained using a structured questionnaire from a sample of high school students. Results showed strong associations with excessive use of smartphones and sleep disorders, eye strain, anxiety, decreased academic performance, and social withdrawal. The study advances knowledge on digital dependency and opens the door for intervention strategies to limit harms associated with digital dependency. Implications for schools, families, and policymakers are outlined, followed by suggestions for future research on adolescent digital well-being. Keywords— Smartphone addiction, digital dependency, high school students, physical health, psychological impact, academic performance, social well-being.
