What could cause excessive sneezing?

Univ. of Nev. School of Medicine, Family Medicine

There are several factors that could cause sneezing. Any foreign particle that can get past the nasal hairs can stimulate the sneeze reflex. These can include seasonal allergies like those caused by pollen, or dust and pet dander. Strong odors from perfumes, tobacco smoke or cooking can also stimulate sneezing. Viruses, cold or hot weather and drying of the nasal lining are also culprits in excessive sneezing. In rare instances, bright sunlight can also trigger the sneeze reflex.

Nose Disorders

Your nose plays a very important part in maintaining your health. As you breathe it filters out the bad stuff in the air like dust and germs. It also moistens the air as you breathe so that your lungs stay hydrated and healthy. You can be miserable if your nose is injured or irritated, whatever the cause. Nose disorders can range from a simple nosebleed or a runny nose that can be treated at home to more serious disorders such as nasal polyps (growths) or a deviated septum (a twist in the wall that separates the two sides of your nose) that may require surgery. Whatever the cause of your nose problem, it's important to know that you can usually be helped by seeing an ear, nose and throat (ENT) doctor.
