‘Day-to-day’ symptom of harmful emissions, which in turn can disrupt sleep, can be overlooked, say researchers

Increased air pollution linked to more night-time coughing, UK-led study finds

TL;DR

  • Increased air pollution is linked to more night-time coughing, disturbing sleep.
  • Research used anonymized data from a sleep-tracking app across 32 cities over 18 months.
  • High daily particle pollution was consistently associated with increased coughing.
  • Coughing increases were noted even at pollution levels below WHO guidelines.
  • Severe pollution spikes, like those from LA wildfires, showed a clear increase in coughing, with some delayed effects.
  • Episodic air pollution from sources like fireworks also correlated with higher cough rates.
  • The study emphasizes the global health relevance of air pollution and the need to address potential chronic effects of long-term low-concentration exposure.
