Eye Movement Desensitization and Reprocessing (EMDR) is a well-researched and effective treatment for reducing or eliminating distress related to trauma or disturbing events. It involves alternating stimuli (e.g. sounds, tones, taps) that help activate the brain to process and resolve negative thinking and discomfort related to "triggering" life events.
According to the EMDR International Association, "Stress responses are part of our natural fight, flight, or freeze instincts. When distress from a disturbing event remains, the upsetting images, thoughts, and emotions may create feelings of overwhelm, of being back in that moment, or of being 'frozen in time.' EMDR therapy helps the brain process these memories, and allows normal healing to resume. The experience is still remembered, but the fight, flight, or freeze response from the original event is resolved.”
Please note that 90 minutes are recommended for an initial EMDR session to support thorough processing.
