Question

eli5: Why does the urge to sneeze suddenly disappear sometimes?

In: 10

Answer 1

In my personal experience it seems to happen when I over-anticipate the sneeze, which somehow overrides it from happening.

Answer 2

The allergen threshold to produce a sneeze has not been met, causing your sneeze to recoil in wait of its next opportunity at freedom.
