Effect of Yoga Intervention for Health Care Workers During the COVID-19 Pandemic: A Systematic Review.

Résumé

BACKGROUND: Health care workers (HCWs) faced unprecedented stress, anxiety, and burnout during the COVID-19 pandemic. Yoga, a mind-body practice combining physical postures, breathing, and meditation, has demonstrated benefits for mental and physical resilience. This systematic review evaluated the effectiveness of yoga interventions in addressing mental health challenges and promoting overall well-being among HCWs during the pandemic.METHODS: This review adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Comprehensive searches of PubMed, EMBASE, and Cochrane CENTRAL were conducted up to November 2024 using terms including "yoga," "COVID-19," and "health care workers." Eligible studies involved HCWs receiving yoga interventions compared with nonyoga controls. Outcomes included stress, anxiety, depression, sleep quality, and physiological parameters. Randomized controlled trials, cohort studies, and observational studies were included. Quality assessment was performed using the Cochrane Risk of Bias Tool (RoB 1.0). Certainty of evidence assessment was conducted with Grading of Recommendations Assessment, Development and Evaluation.RESULTS: Of 134 studies identified, 11 met the inclusion criteria. Participants included HCWs from India, Turkey, and the United States, with intervention durations ranging from 2 to 12 weeks. Yoga consistently reduced stress, anxiety, and depression, with improvements in sleep quality and quality of life. Physiological benefits included enhanced autonomic function and reduced levels of inflammatory markers. App-based and tailored yoga protocols showed potential for scalability and accessibility. The overall quality of the included studies was moderate.CONCLUSION: Yoga interventions demonstrated significant benefits in mitigating mental health challenges and enhancing overall well-being in HCWs during the COVID-19 pandemic. These findings underscore the value of yoga as a holistic support for HCWs in high-stress environments.
