There is ample evidence and expanding coverage on the COVID-19 virus spread across
the world today. The increasing burden of cases has not only overwhelmed our fragile
public health care system but also stressed our economy due to lockdowns. The last
one year of the pandemic has subjected our health care systems, social support systems,
and resilience of our citizens to testing times, as a result of antipandemic measures.
Evidence-based treatment guidelines have been formulated, revised, and advocated by
both Ministry of Health and Family Welfare and Ministry of AYUSH in the last one year
for health care practitioners to treat COVID-19 patients. There has been a clamor
for improving one’s “immunity” and being healthy and fit to reduce the impact of COVID-19.
While the COVID-19 may infect anybody, the predilection, severity of symptoms, and
ability to resist virus infection does depend on physiological and psychological status
of one’s health. This is evident from epidemiological characteristics of this disease
severely affecting the elderly and those with comorbid conditions. Although the evidence
for role of a healthy lifestyle as a primary prevention of COVID is still uncertain,
it nevertheless is known to influence the trajectory of the disease in those affected.
Yoga and meditation as a mind, body and lifestyle intervention has gained popularity
in recent times. Ever since the declaration of International Day of Yoga (June 21)
by the United Nations General Assembly in 2014, yoga, as a health promotion intervention,
has gained popularity globally with due support from majority of the nations and the
World Health Organization (WHO). The present editorial highlights the role of yoga
in prevention and management of COVID and COVID-like acute respiratory illnesses.
The resurgence of COVID-19 in 2021 has enhanced the burden on the health care resources
in our country, with an exponential increase in the number of cases. The highlighting
of deaths due to lack of oxygen beds by the media has created a panic in the country.
People are more anxious than ever before if they have contracted COVID due to uncertainty
in trajectory and ensuing respiratory distress. It has become impossible under these
circumstances to pay attention to and mitigate the psychological distress of every
patient who is under home isolation or under hospitalization. The accompanying psychological
distress in COVID-19 patients is often ignored and not managed. There have been reports
of anxiety and acute depression, leading to suicides during home isolation and in
COVID care hospitals. Social isolation has led to anxiety and led to severe mental
health issues in those with preexisting anxiety or depressive disorders. The constant
fear of getting infection, unbearable stress, long working hours, helplessness, and
distress watching infected patients die alone has caused burnout stress in frontline
health care workers. All these point to a pandemic of psychological distress accompanying
COVID-19.[1]
COVID-19 patients have had to contend with stress due to fear of worsening of symptoms,
respiratory distress, hypoxia, fatigue, insomnia, and other symptoms during COVID-19
infection, which are amplified due to isolation anxiety.[2] The anxiety and uncertainty about the trajectory and course of illness among COVID-19
positive patients, those suspected of COVID-19, and those in quarantine can lead to
psychologic distress which, in turn, can downregulate their immune defenses and increase
the chance and severity of infection, similar to earlier studies. Studies have shown
psychological stress to enhance the rates of infection in communities during a flu
season. Even among the health care workers, impending anxiety and stress can downregulate
immune responses and defenses that can lead them to contract this infection and increase
its severity.[3]
Treatment protocols for people with COVID-19 should address both the physiological
and psychological needs of the patients and health service providers. Providing psychological
treatment and support may reduce the burden of comorbid mental health conditions and
ensure the well-being of those affected.[4] There is some evidence that enhancing general physical and mental health may reduce
burden of acute respiratory illness. In a series of observational and viral inoculation
studies, perceived stress, negative emotion, and lack of social support predicted
not only self-reported illness but also biomarkers such as viral shedding and inflammatory
cytokine activity.[5]
[6] Similarly, both epidemiological and experimental studies have suggested that regular
physical activity such as moderate exercise may protect people from acute respiratory
illness.[7] A recent observational cohort study (n = 1,002 adults) reported 32% to 46% lower incidence, duration, and severity of acute
respiratory infection (ARI) illness among the most active versus least active participants.[8]
The recommended means of aerobic exercise is walking, with an optimal frequency of
three to five days a week and an optimal duration of 20 to 30 minutes of continuous
activity.[9] Moderate exercise is known to increase salivary IgA secretion, which is known to
reduce the risk of infections.[10] In a recent observational study, COVID-19 patients who were physically active and
met physical activity guidelines had less severe form of COVID illness.[11] Studies on yoga and meditation in managing flu symptoms during an influenza season
have shown promising results. A recent randomized trial comparing meditation and exercise
with wait-list control among adults aged 50 years and older found significant reductions
in ARI illness during cold season with mindfulness meditation.[12] Considering that they are a vulnerable group to contract such infections, yoga may
be useful as a preventive measure. In our earlier study, yoga practices such as kriyas, pranayama, and asanas have been shown to reduce airway reactivity and enhance respiratory effort in elderly
subjects with asthma.[13] Thus, modulation of autonomic tone may also be useful in the management of COVID-19
illness, as it can modulate immune response and inflammation. Sufficient evidence
exists to justify testing the hypothesis that training in meditation or exercise can
reduce susceptibility to ARI illness. The ability of yoga to reduce inflammatory markers
in those with obesity or cardiovascular illness and diabetes may be useful in COVID-19
patients with these comorbid conditions. Below is a list of yoga practices that can
be used in management of Covid-19 patients (see [Table 1]).

Yoga and meditative practices can play an important role as an adjunct in reducing
psychosocial distress in the community. Central Council for Research in Yoga and Naturopathy
(CCRYN), an autonomous body under the Ministry of AYUSH, has developed a psychosocial
rehabilitation program for COVID-19 patients in consultation with National Institute
of Mental Health and Neuro Sciences (NIMHANS), Bengaluru, and SVYASA University, wherein
AYUSH doctors will be trained in screening for psychosocial distress, counselling,
and management of psychosocial distress in COVID-19 patients using yoga and naturopathy
approaches. It is important that through socio-culture structuring, the masses are
motivated to engage in regular physical activity, yoga, and meditative practices.
WHO has taken these initiatives the world over as global action plan on physical activity
(GAPPA) program. The fit India movement program of the government of India is also
following the same direction.[14] This apart, COVID-19 patients also need to be educated on lifestyle, diet, and self-care
approaches for managing symptoms during home isolation, involving naturopathy methods
such as steam inhalation, nasal irrigation with saline water, cold sponging for fever,
hot chest pack, arm and foot bath for chest congestion, along with home remedies for
mild symptoms. It is imperative that we adopt an integrated, evidence-based approach
of all health care systems to manage this pandemic effectively.
