Key result
Sudarshan Kriya Yoga markedly reduces daily stress and trends toward lowering awake systolic BP in PTSD.
Why the study?
PTSD is linked to elevated cardiovascular disease risk and hemodynamic dysregulation, but the impact of Sudarshan Kriya Yoga on ambulatory blood pressure regulation and daily stress had not been tested.
Does 8 weeks of Sudarshan Kriya Yoga practice improve PTSD symptom severity, daily stress, and ambulatory blood pressure regulation in patients with PTSD?
Population
7 patients with PTSD
Comparison
Sudarshan Kriya Yoga training and practice vs waitlist control
Design
Randomized controlled trial
Follow-up
8 weeks

SKY may ease PTSD-linked daily BP dysregulation; leaves open whether it reduces long-term CVD events.
RCT (n=7)
Does 8 weeks of Sudarshan Kriya Yoga practice improve PTSD symptom severity, daily stress, and ambulatory blood pressure regulation in patients with PTSD?
Effect estimate: Cohen's d 0.80

Eight weeks of Sudarshan Kriya Yoga practice may improve PTSD symptoms, daily stress perception, and ambulatory blood pressure regulation, potentially reducing cardiovascular risk in this population.
Alpenglow et al. (2026) conducted an RCT in Post-traumatic stress disorder (PTSD) (n=7). Sudarshan Kriya Yoga (SKY) vs. Waitlist control was evaluated on Modified Daily Stress Inventory (DSI) scores for mean stressor severity (Cohen's d 0.80, p=0.04). Sudarshan Kriya Yoga practice for 8 weeks reduced daily stressor severity (p=0.04, d=0.80) and trended toward lowering awake ambulatory systolic blood pressure (p=0.07) in patients with PTSD.
