Trauma doesn’t just affect how we feel — it changes how the brain works.
Parts of the brain that handle fear, memory, and decision-making start to reroute themselves for survival.
▶️The amygdala becomes extra alert.
▶️The hippocampus has a harder time calming the alarm.
▶️And the networks that help us focus or connect with others shift toward keeping us safe instead.
This is what I call The Biology Of Trauma® — when the body’s survival wiring becomes the new normal.
The good news: with the right support, the nervous system can relearn what safety feels like — and the brain can change again.
Some brains remain “on alert” even in calm environments. This reflects survival circuits that continue operating despite the absence of external threat.
