while the exact biological mechanisms linking air pollution and weight gain are complex and multifaceted research suggests that chronic exposure to pm25 may contribute to the development of obesity by

Air pollution may contribute to obesity by inducing insulin resistance, inflammation, and oxidative stress. It has also been linked to decreased physical activity, which can further exacerbate weight gain. Older adults may be more vulnerable to the adverse effects of air pollution, and efforts should be made to mitigate this environmental hazard and promote healthy lifestyle behaviors to reduce the burden of disease.
