Your Cough or Sneeze Goes Farther Than You Thought

We all know to cover our mouths when we cough or sneeze, and now a study from MIT researchers shows not doing so could be riskier to those around you than you thought (on top of being just plain rude).

It turns out our coughs and sneezes have an invisible "turbulent buoyant cloud"—sounds ominous, huh?—that keeps potentially infectious droplets aloft over distances up to 200 times farther than studies previously estimated.

This means droplets can remain airborne long enough to reach ceiling ventilation units, transmitting that nasty cold from one end of your office to the other—and you won’t even know who the perpetrator is. All the more reason to be sure you’re covering your mouth the next time you let out a turbulent buoyant cloud.
