What Does Watching Racist Violence do to Your Health?

'The videos of recent tragic shootings are disturbing and hard for anyone to watch. But it can be even harder if the person in the video looks like you.  “We used to think about problems like PTSD as being caused by a single traumatic event and what we're now starting to understand is that often it's an accumulation of experiences that results in traumatization,” says associate professor of psychology and brain sciences at the University of Louisville, Monnica Williams. Those who experience microaggressions and other racist interactions can be affected, but Courtney Cogburn, an assistant professor at Columbia University’s School of Social Work, says even just watching other people experience racism can cause health problems.
