Recent research from the University at Buffalo has found that cyberbullying has a significant impact on adolescent sleep quality, leading to higher levels of depression. The study, which examined over 800 teenagers, discovered that online harassment disrupts sleep patterns, making it harder for teens to get the rest they need for mental well-being.
The Link Between Cyberbullying, Sleep, and Depression
The study, led by researcher Misol Kwon, explored how negative online interactions contribute to sleep disturbances. Findings suggest that teens who experience cyberbullying are more likely to suffer from poor sleep, which in turn can heighten depressive symptoms.
According to statistics, 15% of teens reported experiencing online bullying, which affected their school performance and emotional health. Researchers emphasize that understanding the connection between cyberbullying, sleep, and mental health is essential for developing better educational programs and preventive measures.
How Much Does Screen Time Affect Teen Well-Being?
A separate study conducted by the University of Oxford analyzed data from over 17,000 adolescents and found that screen time itself has a minimal impact on overall well-being. The research indicates that factors like family relationships, physical activity, and school life have a far greater effect on mental health than time spent on digital devices.
However, the study does acknowledge that screen use, especially before bedtime, can interfere with essential sleep routines. Experts recommend reducing screen exposure at least one hour before sleep to improve rest quality.
What Can Be Done to Protect Teen Sleep?

- Encourage open conversations about online experiences to help teens manage negative interactions.
- Set limits on screen time before bed to allow the brain to relax.
- Promote positive online behavior and educate about the risks of cyberbullying.
- Support school and community programs that raise awareness about online harassment and its effects on sleep.
While general screen time may not be the biggest factor affecting teen mental health, the emotional impact of cyberbullying remains a major concern. Addressing online safety and promoting healthy digital habits can help protect both sleep quality and overall well-being.
