The findings from research on the physiology of emotions shows that an emotional response, especially a difficult one, potentially involves the entirety of the brain and body physiology. This is because an emotional response to a situation is an assessment of the impact of that situation on the wellbeing of the whole organism.
Limiting the overall impact of a situation to one or more places in the brain and body physiology through physiological and energetic defenses in other parts of the body increases not only the level of stress and dysregulation in places where emotion is present but also throughout the organism.
The level of difficulty one has in tolerating an emotional experience is related directly to the level of physiological stress and dysregulation accompanying the emotional experience.
Expanding and supporting the emotional experience to as much of the brain and body physiology as possible instead of concentrating it in one or more places reduces the level of stress and dysregulation involved in the emotional experience, locally (where emotion is present) as well as globally even in places it is not present, so as to make it more bearable. It can be likened to the experience of reduced difficulty in carrying a heavy load with two arms as opposed to one arm.
