Trauma and first responders

Trauma in first responders refers to the psychological trauma experienced by first responders, such as police officers, firefighters, and paramedics, often as a result of events experienced in their line of work. The nature of a first responder's occupation continuously puts them in harm's way and regularly exposes them to traumatic situations, such as people who have been harmed, injured, or killed.
