As more continues to be learned about the impacts of trauma, new and innovative ways to treat trauma and Posttraumatic Stress Disorder are at the forefront of research. Although CBT and other therapies are the recommended treatments, certain lifestyle changes, such as sleep and exercise, have proven efficacious in treating trauma. This study seeks to understand the relationship between exercise, sleep, and PTSD symptomology utilizing a data set collected at The South Texas Research Organizational Network Guiding Studies on Trauma and Resilience among U.S. military veterans. Data analyses revealed that exercise and sleep predict decreases in PTSD symptomology experience alone and together at certain time points. In a mediation analysis, there was a total effect between exercise and PTSD through sleep quality, but there were no direct or indirect effects. Although the relationship between the three is complicated, PTSD symptomology was significantly affected by increased exercise and improved sleep quality.
