A sneeze is controlled by the trigeminal nerve present in our face. When irritants like dust and pollen enter our nose, the trigeminal nerve triggers sneezing to expel them out with huge force and pressure.

Now, many people close their nostrils and mouth to stop a sneeze. But this can lead to transfer of force and pressure inside their heads, thus damaging their eardrums or other tissues.

Normally, sneeze should not be stopped. But in exceptional situations, a relatively safe way to stop a sneeze is to press our finger above our upper lip. Since the trigeminal nerve is also present above our upper lip, such pressing action also sends a signal through that nerve to the brain. This interrupts the sneeze response and distracts the brain, thus helping in stopping our sneeze.
