After a traumatic experience, the brain's threat-detection system can become highly sensitized, producing a range of psychological and physical reactions. These responses are not signs of weakness—they reflect your nervous system's attempt to protect you. Understanding trauma reactions is an important step toward recovery, because it helps you recognize what is happening in your body and mind rather than being controlled by it. Current trauma research (van der Kolk, 2020; Porges, 2021) emphasizes that these responses involve the entire nervous system and can be addressed through targeted therapeutic approaches.
