For those engaged in dangerous or traumatizing work, these audio programs teach critical self-regulation skills to help maintain calm focus and peak performance during up-tempo situations; and stabilize the wide biochemical swings produced by acutely stressful events, even providing extra inoculation against later development of PTSD. Equally effective for military, early responders, medical personnel, journalists and others in dangerous, high-stress circumstances. These exercises teach simple but powerful relaxation skills, through conscious breathing, key word repetition, body scanning, guided imagery for deep relaxation and guided imagery for restful sleep.
