Face masks reduce the distance that airborne pathogens can travel by more than 50%.
That's according to a new study from the University of Central Florida.
Researchers measured the distance that droplets and aerosols travel from people when wearing different types of masks and when not.
Each participant recited a phrase and simulated a cough for five minutes without a face-covering, with a cloth face covering and with a three-layered surgical mask.
The results were a cloth face covering reduced emissions to about two feet compared to the four feet of emissions produced when coughing or speaking with no mask on.
The reduction was even greater when wearing a surgical mask, which cut the distance of emissions to only about half a foot.
