A 43-year-old-married male diagnosed with coronavirus disease 2019 (COVID-19) in July 2020. His symptoms as described by him began with cough and sore throat, breathlessness, generalized body weakness, irritability, stress, and mood swing for a period of one week. He was admitted in our District COVID Care Center (DCCC) located in Tamil Nadu, India. He underwent Integrated Yoga and Naturopathy (IYN) [i.e., Conventional medicine + yoga and naturopathy] for two weeks. The results showed negative Reverse Transcription Polymerase Chain Reaction (RT–PCR) test for COVID-19, improvement in cardiovascular functions (i.e., a reduction in systolic and diastolic blood pressures, pulse rate, mean arterial pressure, rate pressure product, and double product) and mental health (i.e., a reduction in depression, anxiety, and stress levels). The results suggest that IYN might improve cardiovascular and mental health of patients with COVID-19 in addition to positive to negative conversion of RT–PCR. However, further studies are required to warrant these results.
