Dr. Don Wood explains that unresolved childhood trauma can persist as a chronic fight-or-flight response, repeatedly reactivated by sensory reminders (example: seeing a white van after a car accident). He links this ongoing activation to chronic inflammation, compromised immune function, autoimmune disorders, and gut/stomach problems via the vagus nerve, and recommends resolving trauma by "resetting" or "rebooting" the traumatic memory.

A lot of people aren't aware that trauma from their childhood can affect them and make them feel sick as an adult. A lot of people who have had trauma stay in a fight or flight response because of the way the memory has been recorded. For example, say you got into a car accident with a white van, and then every time you see a white van, your mind that operates in the present sees that accident again in real time. And then that's going to create a physiological response. So if that's constantly going on, you're going to have a constant inflamed state. Inflammation is the response to physical or emotional trauma, and then that inflammation is going to compromise your immune system. If you've got a compromised immune system and now a virus gets into your bloodstream, chances are it's going to overwhelm it. If you have autoimmune disorders, that is a pretty good indicator that there's unresolved trauma. The gut is a second brain. There's a vagus nerve. It's the largest cranial nerve in the body. It stretches from the brain stem down into the stomach and is communicating between whether you're in danger or not in danger. That's why so many people end up with stomach issues, because there's a constant inflammation showing up in the gut area. So the way to resolve this is to get to the root cause, which is if they were a traumatic experience as a child that was stored as a very, very vivid memory, you've got to reset or reboot the memory. Otherwise it's going to continue to activate the system and keep it an inflamed fight or flight response.
