This is a prospective cohort, before-after trial. 20 subjects with PTSD or PTSD symptoms (per patient report) will use the Chilipad nightly for 5 weeks after completing a short battery of PROMIS questionnaires. During the 5-week study intervention, subjects will also wear an OURA ring on a finger. The OURA week measures sleep duration and quality. 5 weeks after study enrollment, patients will repeat the battery or PROMIS questionnaires and will return the Chilipad and OURA rings, both of which will be provided free of charge by the Chilipad and OURA manufacturers
