How Fast Is Cough Droplet?

A cough fires droplets at 19 m/s — 70 km/h. Droplets can travel up to 6 metres before settling, which is why standard recommendations during respiratory illness are to cover your mouth or stay home.

Coughing alone burns roughly 2 calories — but a chronic cough over a day can burn over 100 calories from muscular effort.
