5. Allergies
For some of us, our bodies recognize otherwise harmless particles as something that might cause us harm. These are known as allergies, and an allergen is a particle that can trigger a reaction. There are many types of allergies and one of the most commonly experienced is hay fever. The symptoms of hay fever include a runny nose, watery and itchy eyes, coughing, fatigue and, of course, sneezing.
One of the main purposes of the symptoms of allergic reactions is to try to expel the allergen from the body. In sneezing, we will hopefully expel any allergens that have been inhaled into the nasal passage.
