A UK-led study found that increased air pollution is associated with more night-time coughing, which the researchers say can disturb sleep.
Researchers noted the symptom is often overlooked, as most air pollution research focuses on symptoms severe enough to require medical attention.

Why it matters: Night-time coughing represents a sleep-disrupting effect of air pollution that researchers say is routinely missed because studies prioritize severe outcomes — meaning everyday exposure consequences for people in polluted areas may be chronically undercounted in public health assessments.
