Because traumatic experiences can often be emotionally and physiologically overwhelming, the body stores the memories, thoughts and emotions of the trauma in order to process them at a later date. The high chemical charge left in the body after stress, anxiety or trauma continually seeks a discharge from this over-stimulation. The brain and body work together to try to release this over-excited state so that it can return itself back to a calm and relaxed state. Post Traumatic Stress (PTS) is the term used to explain the continuation of disturbing thoughts, emotions and feelings that persist even after the tension is over. Chronic stress, anxiety or PTS is caused by the lack of release of the high excitement or anxiety that was generated at the time of the difficult event(s).
