Abstract

PM2.5 pollution is expected to worsen in many places due to climate change, as a result of hotter temperatures, less precipitation, and increases in wind speed. PM2.5 exposure has adverse effects on humans that may accelerate the aging process, such as worsening cognitive functioning and cardiometabolic disease. Less is known about whether physical and mental health conditions mediate the relationship between PM2.5 exposure and aging-related cognitive and functional limitations.

Research summary

Fine particulate matter (PM2.5) exposure is linked to lower executive functioning in middle-aged and older adults, with cardiometabolic disease acting as a mediator. The paper is relevant as it explores environmental factors that may contribute to cognitive decline and aging, addressing potential root causes of age-related cognitive impairments.
