Generally, it is believed that severe emotional pain takes a long time to heal. In fact, EMDR shows that the mind can indeed heal from psychological trauma much like the body can recover from physical trauma. For example, when you cut your hand, your body works to heal the injury. Foreign objects or repeated injuries can cause the wound to fester and become painful. Once the obstruction is removed, healing continues. EMDR demonstrates that mental processes follow a similar sequence of events. The brain's information processing system naturally moves toward mental wellbeing. As a result of the impact of a disturbing event, the system can be blocked or imbalanced, causing the emotional wound to fester and cause deep suffering. Once the block is removed, healing can resume. Through the detailed protocols and procedures learned in EMDR therapy training sessions, clinicians help clients activate their natural healing processes.
