Reactivity describes the property of responding with heightened intensity to stimuli — emotional reactivity (intense responses to interpersonal or emotional triggers), physiological reactivity (exaggerated stress responses to provocation), and sensory reactivity (intense responses to physical stimuli). High emotional reactivity may reflect PTSD (where threat system sensitisation amplifies responses), ADHD (emotional impulsivity), borderline personality features, PMDD, or chronic stress and sleep deprivation depleting regulation reserves. High physiological reactivity reflects a nervous system with low activation thresholds — going from rest to high arousal quickly and returning slowly.

What lifestyle changes can help with reactivity?

Nervous system regulation practices (breathwork, yoga, cold exposure) lower baseline reactivity over time. Sleep and stress management protect the regulation threshold.

What integrative approaches support reactivity?

DBT has strong evidence for emotional reactivity reduction. EMDR for trauma-related reactivity. ADHD treatment for impulsive emotional reactivity.

When should I seek professional support for reactivity?

Seek assessment for reactivity significantly impairing relationships or daily life. Trauma-informed therapy, DBT, and ADHD assessment are relevant depending on the driver.
