People exposed to air pollution experienced Covid-19 as if they were 10 years older, according to research. It found people recently exposed to dirtier air before contracting the illness spent four days longer in hospital, the same impact as on those 10 years their senior.
The Belgian study also showed that air pollution levels measured in patients’ blood were linked to a 36% increase in the risk of needing intensive care treatment. A separate study in Denmark showed air pollution exposure was linked to a 23% increase in the risk of death from Covid-19. In both studies, the level of air pollution was below legal EU standards.
