Fine particles reach the small airways and trigger inflammation. For people with asthma, COPD or ischaemic heart disease, this shows up as night cough, reliever over-use, breathlessness on stairs and, at population level, more admissions.
There is no safe exposure; the practical goal is reducing dose on bad days.
Breathlessness at rest, inability to speak full sentences, blue lips or reliever not helping are emergencies.
Persistent night cough beyond two weeks or wheeze on most days needs a lung function review, not repeat antibiotic courses.
Prevention guidance consistent with WHO air-quality recommendations; no AQI numbers fabricated.
