Background The COVID-19 pandemic has created unprecedented challenges for healthcare globally, the brunt of which has been borne by the health care providers (HCPs). These challenges are felt more keenly in India, as they stretch an insufficiently resourced healthcare system. The long hours, cross over of responsibilities, lack of resources to adequately care for patients, and concerns around safety of self and loves ones, have led to a spike in anxiety, depression, insomnia and other stress – related disorders in healthcare providers. Sudarshan Kriya Yoga (SKY) is a mind-body intervention that has been studied in multiple clinical populations. Prior to this study, there has been no exploration of the impact of SKY on healthcare providers, specifically the impact of a mind-body intervention like SKY on HCPs during a pandemic. Objective This study aims to investigate the impact of SKY on the well-being of HCPs during the COVID-19 pandemic. Methods We conducted a pilot feasibility study with a single arm pre-post design. SKY was taught to participants in a 4-day online breath and meditation workshop. We measured outcomes related to depression, anxiety, resilience, life satisfaction, and quality of sleep. Results Ninety-two subjects completed the study survey before and after the intervention. A significant reduction was observed in the levels of stress, anxiety and depression immediately after the program. In addition, the participants reported sig1nificant improvement in life satisfaction, resilience, and the quality of their sleep. Conclusion The results indicate that SKY breathing technique had a positive impact on the well-being of healthcare professionals during the pandemic. Participants experienced improved quality of sleep, enhanced satisfaction with life, and increased resilience after SKY. This pilot study provides important data for future multi-site randomized controlled trials to study the impact of yogic techniques on well-being of the HCPs.

Yoga nidra, also known as ‘yogic sleep’, is a simplified form of an ancient tantric relaxation technique. The most general description of the practice is that it combines guided mental imagery with a specific yoga posture called Shavasana (or “corpse pose”). The goal of yoga nidra is to promote a profound state of relaxation, which differs from sleep inasmuch as there is still an awareness of one’s surroundings. While several components of the practice have been known since ancient times, it was not until the 1960s that an updated and systematized system of practice was introduced to the public through the writings of Swami Satyananda Saraswati. Unlike other schools of yoga, which emphasize concentration or contemplation, yoga nidra’s goal is complete relaxation. As such, its advocates claim that it is suitable for all individuals, from beginners to advanced practitioners of yoga. The calm inner stillness induced by yoga nidra is claimed by practitioners to be an effective stress management tool as well as a means for attaining greater receptivity to personal resolutions. These resolutions can range from the goal of achieving self-transformation, enhancing creativity, or improving one’s learning ability. Additionally, yoga nidra is claimed to promote beneficial changes in physiological and mental health. The following narrative review summarizes the basic steps used to achieve the final state of yoga nidra relaxation as well as some recent experimental findings regarding its physiological and psychological effects. Standard research databases were searched for relevant articles. Clinical studies have shown that yoga nidra meditation is associated with positive physiological changes, including improvements in several hematological variables, red blood cell counts, blood glucose levels, and hormonal status. Two neuroimaging studies have shown that yoga nidra produces changes in endogenous dopamine release and cerebral blood flow, a further confirmation that its effects on the CNS are objectively measurable. The practice has also been shown to reduce psychometrically measured indices of mild depression and anxiety, although these benefits were not shown in an experimental study to extend to severe depression or severe anxiety.

The entire world stood still when the novel coronavirus struck wrath, disrupting the psychological and socioeconomic lives of mankind. Coronavirus disease 2019 created a disastrous impact globally, mimicking a war-like situation. India witnessed extensive lockdown, aimed at limiting the transmission of infection by reducing human contact. This uncertain situation sowed fear and anxiety in the minds of the population, affecting their mental well-being. People are trying to cope with the double whammy of spiking infections and economic instability due to halted businesses. This study attempts to capture the prevalent stress and anxiety in the general population and to highlight the differences in coping with stress and anxiety between the yoga and non-yoga practitioners. Rhythmical yogic breathing, Sudarshan kriya yoga, has shown several beneficial effects in alleviating anxiety, depression, and posttraumatic stress. The observations from this study strengthens the evidence that yoga is effective to maintain mental well-being even during unusual times.

Background: COVID-19, caused by SARS-CoV-2 is one of the major health crisis that has affected the world in the past century. With the emergence of new strains of viruses and antimicrobial resistance, the world is looking for an alternate therapeutic option to fight infectious disease.Objective: The present study evaluated the efficacy of a novel polyherbal formulation, named NOQ19, against SARS-CoV-2 in an in vitro setting. NOQ 19 is an unique blend of 13 Ayurvedic herbs.Methodology: Vero E6 (CL1008), the African green monkey kidney epithelial cell, were infected with SARS-CoV-2 virus (isolate USA-WA1/2020) in a 96 well-plate. NOQ19 test material was diluted in different concentration as follows 0.05mg/ml, 0.1mg/ml, 0.2mg/ml, 0.3mg/ml, 0.4mg/ml, 0.5mg/ml, 0.6mg/ml, 0.7mg/ml, 0.8mg/ml and 0.9mg/ml. These different concentrations of NOQ19 were added to infected cells respectively and incubated for 3 days in 5% CO2 incubator. Remdesivir was used as a positive control.The cells were finally fixed with formaldehyde, stained with crystal violet and plaques were visualized. The number of plaques were counted to determine the PFU(plaque forming units)/mL.Results: Results demonstrated 100% antiviral efficacy of NOQ19 at 0.9mg/ml concentration with complete elimination of the virus. The IC50 of the drug was found to be 0.2mg/ml. The results of the present study demonstrated viral load reduction in SARS- CoV-2 infected Vero E6 cell lines.Conclusion: The result along with clinical trials could propose NOQ19 as a potential therapeutic option in the fighting the COVID-19 challenge.
