How stress affects your body - Sharon Horesh Bergquist. Yes...Stress from Post Traumatic Stress Disorder (PTSD) has made me sick. I have posted many articles on this blog about mindfulness and de-stressing through meditation and I strongly believe that they are all viable practices for lowering daily stress.The stress associated with Trauma, on the other hand, is a whole different creature and requires speciality care from a professional mental health practitioner and possibly the use of specific medications might lower the affects of stress, PTSD and other chronic conditions associated with trauma.
