Air pollution drives elder frailty

A global review of 10 studies across 11 countries finds outdoor particulate pollution raises the risk of frailty in middle and old age. In the UK, an estimated 10–20% of frailty cases may be attributable to outdoor particles, with men in some studies more vulnerable than women. Secondhand smoke boosts frailty risk by ~60%, and solid‑fuel cooking/heating adds additional risk. — This links environmental exposure to functional decline and care needs, making air‑quality and anti‑smoking policy part of aging and health‑system planning.

Both claims frame an environmental exposure (here: infrasound rather than chemical air pollution) as producing measurable physiological harm; this article provides saliva‑cortisol data from a 36‑person controlled experiment (Rodney Schmaltz et al., 18 Hz infrasound via hidden subwoofers) linking built‑environment noise to stress responses, extending the broad idea that ambient environmental factors have direct public‑health effects.
