What purpose does ptsd serve the human body?

It's a disorder: Ptsd serves no useful purpose, per se. It is a troubling anxiety disorder that occurs like an echo of a horrible sound we wish we never heard. It is a disorder and is not beneficial to the human body. That's why we, who treat patients with it, are helping people move beyond it and return to a peaceful, satisfying life.

Adaptive to danger: The same sxs that are found in ptsd can be adaptive in combat. Waking at a moment's notice can save your life. Battle breathing- rapid breathing & heart rate occur when engaged in battle. Hypervigilance makes you aware of danger. Emotional numbing allows you to respond to the immediate. Compartmentalization allows one to engage in war. The problem is when the sxs don't dissipate when it is safe.
