Introduction: The present study analyzed the association between bullying and cyberbullying victimization and aggression, and the light and deep sleep-in adolescents. Recent literature, exposes that bullying can negatively affect sleep quality, interfering with physiological processes essential for recovery and emotional well-being. Method: A cross-sectional study was conducted with 985 Andalusian adolescents (10-16 years old), who wore Xiaomi Mi Band 4 bracelets for seven days to record the duration of sleep phases. Validated questionnaires were applied to measure bullying and cyberbullying, and data were collected on age, sex, BMI and moderate-vigorous physical activity level. Multiple linear regressions were used to analyze covariate-adjusted associations. Results: Bullying victimization was significantly associated with worse sleep, both light (β = -7.267; p = .049) and deep (β = -1.479; p = .048). Likewise, greater cyberbullying victimization showed worse deep sleep (β = -5.278; p = .018). No significant associations were found between aggression behaviors in both bullying and cyberbullying and sleep phases. Conclusions: The results indicate that young people who suffer bullying/cyberbullying show significant sleep disturbances. These findings underscore the need for preventive interventions focused on mitigating the consequences of bullying at a young age.
