Psychological effects

Exposure to constant news coverage of war can lead to stress and anxiety. Television coverage of the destruction of the World Trade Center in 2001, which repeated the same footage over and over, led to symptoms of trauma experienced across the United States. Studies have indicated that children have been traumatized by exposure to television of other frightening events, including the Challenger disaster. Journalists themselves also experience trauma and guilt.

Research also suggest that constant representations of violence in the news lead people to overestimate the frequency of its occurrence in the real world, thus increasing their level of fear in everyday situations.
