The purpose of this study is to learn more about the effectiveness of a prescription wrist-wearable device called NightWare (NW) on improving sleep in Veterans with nightmares related to posttraumatic stress disorder (PTSD). The investigators also want to learn whether it improves cardiovascular health among this population.
Diagnosis of PTSD via American Psychiatric Association PTSD diagnostic criteria in the fifth edition of its Diagnostic and Statistical Manual of Mental Disorders (DSM-5).

Unstable medical condition (e.g., uncontrolled hypertension or active CVD or cancer);
Active infection (note, anyone with an active infection would become eligible once the infection has ended);
