This study expanded the current literature by assessing PTSD in relation to reactivity and recovery from negative emotional arousal among OEF/OIF/OND Veterans. Cardiac impedance was employed during a speech task and a trauma imagery procedure. Those in the PTSD-S group displayed lower SBP and higher TPR reactivity relative to the PTSD- and PTSD+ groups; lower CO reactivity relative to the PTSD+ group; and more CO recovery than those in the PTSD+ group to the trauma task. For speech task, Veterans in the PTSD-S group exhibited lower HR reactivity for both speech preparation and delivery than those in the PTSD- group. …

Exposure to images of nature following a stressful event can reduce physiological measures associated with stress. The objectives of this study was to determine whether exposure to nature before the stressor can buffer the stress response. We varied whether nature or urban images were viewed before or after a stressor and measured galvanic skin response in our participants. We describe how order of presenting the stressor influences nature’s calming effect on physiology.
