When humans are frightened, they remember things very clearly. Although it can be distressing to remember these things, it can help to understand what happened and, in the long run, help us to survive. The flashbacks, or replays, force the sufferer to think about what has happened. The individual can decide what to do if it happens again. After a while, he or she learns to think about it without becoming upset. It is tiring and distressing to remember a trauma. Avoidance and numbing keep the number of replays down to a manageable level. Being "on guard" means that the sufferer can react quickly if another crisis happens. It can also give individuals the energy for the work that's needed after an accident or crisis. But the sufferer doesn't want to spend the rest of their life going over it. They only want to think about it when they have to, such as if the sufferer finds themselves in a similar situation.

Adrenaline is a hormone our bodies produce when we are under stress. When the stress disappears, the level of adrenaline should go back to normal. In PTSD, it may be that the vivid memories of the trauma keep the levels of adrenaline high. This will make a person tense, irritable, and unable to relax or sleep well. The hippocampus is a part of the brain that processes memories. High levels of adrenaline can stop it from working properly. This means that flashbacks and nightmares continue because the memories of the trauma can't be processed. If the stress goes away and the adrenaline levels get back to normal, the brain is able to repair the damage itself, like other natural healing processes in the body. The disturbing memories can then be processed and the flashbacks and nightmares will slowly disappear.
