Straying away from a sedentary lifestyle is essential, especially in these troubled times of a global pandemic to reverse the ill effects associated with the health risks as mentioned earlier. In the view of anticipated effects on immune system and prevention against influenza and Covid-19, globally moderate to vigorous exercises are advocated wearing protective equipment such as facemasks. Though WHO supports facemasks only for Covid-19 patients, healthy "social exercisers" too exercise strenuously with customized facemasks or N95 which hypothesized to pose more significant health risks and tax various physiological systems especially pulmonary, circulatory and immune systems. Exercising with facemasks may reduce available Oxygen and increase air trapping preventing substantial carbon dioxide exchange. The hypercapnic hypoxia may potentially increase acidic environment, cardiac overload, anaerobic metabolism and renal overload, which may substantially aggravate the underlying pathology of established chronic diseases. Further contrary to the earlier thought, no evidence exists to claim the facemasks during exercise offer additional protection from the droplet transfer of the virus. Hence, we recommend social distancing is better than facemasks during exercise and optimal utilization rather than exploitation of facemasks during exercise.
摒弃久坐不动的生活方式至关重要，尤其是在全球疫情肆虐的当下，以扭转前文所述的与健康风险相关的不良影响。鉴于对免疫系统的预期影响以及预防流感和新冠病毒，全球倡导适度至剧烈运动，并佩戴口罩等防护设备。尽管世界卫生组织仅支持新冠患者佩戴口罩，但健康的“社交锻炼者”也会戴着定制口罩或N95口罩进行剧烈运动，而这些口罩被认为会带来更严重的健康风险，并给包括肺部、循环系统和免疫系统在内的各种生理系统增加负担。戴着口罩锻炼可能会减少氧气供应并增加空气滞留，阻碍大量二氧化碳交换。高碳酸血症性缺氧可能会增加酸性环境、心脏负荷、无氧代谢和肾脏负荷，这可能会大大加重已确诊慢性病的潜在病理状况。此外，与之前的想法相反，没有证据表明运动时佩戴口罩能提供额外的病毒飞沫传播防护。因此，我们建议在运动时保持社交距离比戴口罩更好，并且要合理使用而非滥用运动时的口罩。
