Facebook addiction, also known as F.A, is a dangerous new type of addiction similar to alcoholism and drug addiction. F.A is characterized by excessive time spent on Facebook and an inability to limit use. Signs of F.A include oversharing personal details, constantly checking for updates and likes, and spending hours browsing profiles daily. F.A can negatively impact people psychologically by causing feelings of sadness when posts aren't liked, as well as harming physical health through eye strain and sleep issues. It can also damage work productivity and offline relationships. To avoid F.A, people should set limits on Facebook use, turn off notifications, and focus on real world interactions with friends and family instead of online activities.
