Which environmental cue is associated with coughing?

Coughing is primarily linked to environmental cues related to air quality and pollutants. When the respiratory system detects irritants in the air, such as smoke, dust, or allergens, it triggers a reflex response to clear the airway, resulting in coughing. This physiological reaction is essential for protecting the lungs and maintaining clear air passages. Airborne irritants are therefore a significant cue for coughing, distinguishing it from other factors like food or social determinants, which do not directly influence the respiratory reflex in the same manner.
