“…There must be greater national and international sensitivity to how restrictive measures impact human movement ( 20 , 21 ). Indeed, a recent article investigating non-viral parameters associated with death rate, researchers found that the national criteria most associated with death rate were: life expectancy (and its slowdown), a public health context [e.g., metabolic and non-communicable diseases (NCD) burden vs. infectious diseases prevalence], the economy (e.g., growth national product, financial support), and the environment (e.g., temperature) ( 22 ). Enforcing strict measures to fight the COVID-19 pandemic, including lockdown, were not linked with death rate, and moreover, the authors suggested that a better understanding of the inherent factors which affect COVID-19 mortality may improve prevention strategies, one of which was highlighted as increasing population immune resilience through better physical fitness ( 22 ).…”
