Nugget of Knowledge: Sneeze and blink

Sneeze droplets fly 30 feet at 100 mph


YOUNGSTOWN, Ohio (WYTV) – The anatomy of a sneeze is pretty disgusting.

For someone with a cold, allergies, or just a tickle in the nose, it takes less than a second to eject about 5,000 droplets of mucus from their nostrils at speeds of up to 100 mph.

Those infectious snot particles can travel up to 30 feet and remain suspended in the air for up to 10 minutes, creating a plume of bad air that threatens anyone in its path.

Our body doesn’t mind delivering germs at high velocity, but it doesn’t want to look at it.

During a sneeze, most everyone involuntarily closes his or her eyes as a reflex action.

The nose and eyes are linked by cranial nerves, so the stimulation from the sneeze travels up one nerve to the brain, then down another nerve to the eyelids, triggering a blink for most people.
