Effects of social media to people

Anxiety
Research suggests that young people who spend more than 2 hours per day on social media.

Cyber bullying
is a bullying that bully people on internet or in social media apps.

Sleep
social media use has a significant association with poor sleep quality in young people. Using phones, laptops, and tablets at night before bed is also linked with poor quality sleep.

How to prevent bullying
For me if you want to prevent bullying encourage schools and day care facilities to participate in an anti-bullying training.
Encouraging kids to be confident and accepting of others will help prevent a bullying situation.
