Cough hypersensitivity risk increases during heatwaves and can be reduced by inhalation of alkaline aerosols of endogenous ions

Short summary

Heatwave exposure increases cough hypersensitivity by causing upper-airway mucosal collapse, a condition reversed by inhaling alkaline aerosols of endogenous ions (pH > 8.3), which reduced daily cough bouts by 59% in a clinical trial.
