This is why you sneeze when you pluck your eyebrows
It's probably not the best time to be sneezing, but a majority of people find they're overcome with sneezes every time they tweeze their eyebrows.
We get it, we've been there. Your nose starts to wrinkle, your eyes tear up and your waxing specialist instinctively knows to take a step back.
That's because plucking (or waxing or threading) stimulates the trigeminal, a facial nerve that branches down to the tip of your nose.
"The reason that many people sneeze when they tweeze their eyebrows is that the eyebrows and the nose are both innervated by the trigeminal nerve. When the trigeminal nerve is stimulated by eyebrow tweezing, this causes excitement of the nerve in the nasal area as well...which can lead to a sneeze," said New York dermatologist Eric Schweiger.
Basically, it's a reflex that is also responsible for us tearing up."It is a reflex. It has to do with the way we humans are wired and it is odd to say the least," dermatologist Jeanine Downie explained.
There's a way to stop it, too. Dr. Cynthia Boxrud suggests pressing a finger to the eyebrow, with pressure, as to "short-circuit the wiring of the trigeminal nerve." See Gallery
