Sneezing is an involuntary action that expels air, along with irritants and allergens from the nose. It is a natural reflex that the body employs to protect itself from harmful substances that enter the nasal passage.

However, if you find yourself sneezing frequently, it could be a sign of an underlying health issue. Here are thirty possible reasons for frequent sneezing:.

Allergies occur when the immune system overreacts to harmless substances such as pollen, dust, and animal dander.

When you inhale an allergen, the body releases histamine, a chemical that triggers the release of mucus, causing sneezing, itching, and congestion.
