Body-first regulation
Start with paced breathing, progressive muscle release, or short movement to reduce physiological arousal. When the body is in a stress response, cognitive tools like reframing are harder to access because the prefrontal cortex is less active.
Diaphragmatic breathing at a pace of about six breaths per minute has been shown in research to activate the parasympathetic nervous system. A simple version: breathe in for four counts, out for six counts, with your hand on your belly to ensure deep rather than shallow chest breathing. Repeat for two to three minutes.
