Why do some people have a stronger sneeze reflex than others?
Quick Answer
Sneezing is a protective reflex that varies with nasal nerve sensitivity and irritation. Allergies, dust, infection, and even bright light can trigger it more easily in some people.
The Full Story
A sneeze clears the nose when sensory nerves detect irritation in the nasal lining. People differ in how sensitive those nerves are, so some sneeze at tiny triggers while others do not. Allergies, colds, dry air, perfumes, and dust can all set off the reflex. Some people also experience photic sneezing, where bright light triggers sneezing through a neurological reflex. The sneezing response is common and protective, but unusually frequent sneezing may reflect allergies or another condition.
