Background and objectiveCoronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a highly contagious infectious disease that has affected many countries globally. Attangaogam, known in Sanskrit as "Ashtanga yoga", is a practice associated with the spiritual and cultural heritage of India whose origins can be traced back to the very dawn of civilization; the practice of yoga promotes health, healing, and longevity. This study aimed to analyze the effects of Attangaogam (Athanam) yoga asana-Pranayamam practice on biochemical, inflammatory, and hematological markers in the management of COVID-19.Materials and methodsA prospective observational study was conducted from August 2021 to February 2022 among hospitalized adult patients of both sexes who consented to participate and tested positive for COVID-19 reverse transcription-polymerase chain reaction (RT-PCR). Convenience sampling was employed and the study was approved by Institutional Ethics Committee (VMCIEC/74/2021). Clinical details, inflammatory markers, D-dimer, lactate dehydrogenase (LDH), ferritin, procalcitonin (PCT), interleukin 6 (IL-6), and complete blood count (CBC) were analyzed for all the volunteering patients on admission and before commencing yoga-pranayamam practices. Also, the parameters were recorded after practicing the scheduled protocol: on the day of discharge, and after the first and third months of discharge. Microsoft Excel 2013 was used for statistical analysis.ResultsOf the 76 patients, 32 were followed up regularly; the mean age of the cohort was 50.6 ± 4.95 years, and 62% were males. All the patients attained normal oxygen saturation and got discharged in 7-14 days. The comparison of clinical, hematological, inflammatory, and biochemical investigations between pre- and post-Attangaogam yoga-Pranayamam practice sessions showed statistically significant differences and the patients attained normal levels for all variables within three months except for serum albumin.ConclusionBased on our findings, the practice of Attangaogam yoga-Pranayamam contributed to the successful treatment of COVID-19 with the early restoration of protracted hypermetabolic and hyperinflammatory markers to normal status. The evidence related to biomarkers revealed that the patients attained metabolic normalcy of cell health with the aid of personalized physical rehabilitation counteracting inﬂammation and promoting tissue repair thanks to holistic natural and innate immunity provided by Attangaogam yoga-pranayamam practices.
