ABSTRACT
BACKGROUND: Kundalini Yoga (KY) integrates breathwork, meditation, dynamic movement, and chanting, and has gained recognition as a therapeutic intervention. Despite promising results from individual randomized controlled trials (RCTs), to our knowledge, no systematic review has exclusively synthesized RCT evidence on KY across health domains.
OBJECTIVE: To critically assess the clinical effectiveness and safety of KY interventions across diverse cognitive, psychological, emotional, sleep-related, and physical health outcomes.
METHODS: PRISMA-guided systematic review of RCTs evaluating KY was conducted from January 2015 to December 2024. Databases included MEDLINE (PubMed), Scopus, CENTRAL (Cochrane Library), Embase, PsycINFO, and CINAHL. Risk of bias was independently assessed using the Joanna Briggs Institute Critical Appraisal Checklist.
SETTING: Studies were conducted worldwide, across multiple sites.
PARTICIPANTS: Approximately 1370 participants ranging from healthy adults to those diagnosed with conditions such as Mild Cognitive Impairment (MCI), Generalized Anxiety Disorder (GAD), Obsessive-Compulsive Disorder (OCD), Post-Traumatic Stress Disorder (PTSD), insomnia, chronic pain, and post-treatment Lyme disease syndrome. No serious adverse events were reported.
INTERVENTION: KY protocols (pranayama, asana/kriya, meditation, chanting) delivered in person, online, or hybrid formats; duration 6 weeks-12 months (most 8-12 weeks) with practice from once weekly to daily.
OUTCOME MEASURES: Pre-specified validated measures assessed cognitive function, psychological symptoms (e.g., anxiety, depression), sleep quality, emotional regulation, and physical health outcomes (e.g., hippocampal metrics, absenteeism, blood pressure).
RESULTS: This systematic review included 15 studies, among which 13 demonstrated a low risk of bias. The findings suggest that KY significantly improves memory, executive functioning, and hippocampal structure, reduces symptoms of anxiety, PTSD, OCD, and depression, enhances sleep quality and emotional regulation, and modestly improves fatigue, blood pressure, and functional outcomes.
CONCLUSION: KY appears safe and shows benefits for a wide range of cognitive, psychological, and physical health conditions. However, larger, standardized RCTs with active comparators, biomarkers, and longer follow-up are needed.
