real-life toxicants as an emerging challenge in the rehabilitation of covid-19 survivors

Awareness of covid-19 infection, as a public crisis, makes an emergency condition for survivors. regarding the importance of early rehabilitation, we should pay particular attention to the potential risk of real-life toxicants in covid-19 survivors. the adverse effects underlying covid-19 infection lead to persistent sequelae in survivors. in addition, complete rehabilitation is challenging in seriously-ill patients due to cytokine storm severity, inflammation, oxidative stress, and cell death contributing to multi-organ damage. different foods, environmental/occupational pollutants, and unhealthy lifestyles are real-life examples of toxicants that can pose redox imbalance and oxidative damage to the biological system. the key concept is that survived patients with persistent tissue damage, low-grade inflammation, oxidative stress, and fibrosis are susceptible to real-life toxic stressors, which have the potential for oxidative stress. moreover, fibrosis are susceptible to toxic stressors, which can induce harmful effects by promoting oxidative stress and pro-inflammatory components. this paper attempted to elucidate a vital toxicological concept in which the existing sequelae of covid-19 survivors increase the potential risk of real-life toxicants and to propose a practical strategic approach to reduce toxicant exposure.
