Smaller droplets can also stay in the air for longer periods, while large droplets fall more quickly to the ground after a sneeze. Lydia Bourouiba at the Massachusetts Institute of Technology used high-speed video to study the distance travelled by sneeze particles. She found that the hot, moist gas cloud produced by a sneeze helps the expelled respiratory particles avoid evaporation longer, and that airflow or ventilation systems in any given room can contribute to sneezes travelling further.
Coughs are a repetitive reflex that helps clear large breathing passages your lungs and bronchial tubes of irritants, foreign particles and nasty bugs. When you cough, there are three stages —inhalation, forceful exhalation against closed up vocal cords and a violent release of air following the opening of the vocal chords, which explains your Uncle Joe's distinctive sounding cough.
Some coughs are to clear your airways quickly, but a chronic cough could be a sign of something more serious. Both a sneeze and a cough have one goal in mind: getting rid of whatever is bugging your body. Unfortunately, getting rid of germs in such a violent method means spreading germs in a rather large spray of saliva, mucus, irritants and caught viruses which can live on surfaces for hours at a time.
Sprays can be a little difficult to track, but some enterprising scientists have managed to make a rough estimate. A cough can travel as fast as 50 mph and expel almost 3, droplets in just one go.
Sneezes win though—they can travel up to mph and create upwards of , droplets.
