As the world is dealing with the COVID-19 pandemic, people’s lifestyles have also been affected. The present study was conducted to explain the components of lifestyle in patients who have recovered from COVID-19. This qualitative study was conducted with a phenomenological approach on 16 people recovered from COVID-19 living in Tehran. The participants were selected by purposive sampling, and in-depth unstructured interviews were held with them. The data were analyzed in MAXQDA. Four main categories were extracted as the components of the lifestyle of patients recovered from COVID-19, including physical problems (with the subcategories of frailty and feeling old, and post-recovery physical symptoms), physical activity (with the subcategories of inability to take a walk, and inability to exercise), nutrition (with the subcategories of loss of appetite, taking supplements, and compliance with healthy eating), psychological problems (sleep disorder, obsession, stress, anxiety about infecting family and friends, and neurological disorders). The alterations in people’s lifestyles due to the COVID-19 pandemic and the protocols imposed to prevent the disease transmission are undeniable. Health planners and policy-makers should therefore pay particular attention to these changes as new challenges, especially in designing lifestyle-related interventions.
