Sneezing
Sneezing is also a symptom of other upper respiratory infections, such as the flu and pneumonia. In this brief, I will discuss sneezing and why it is associated with these other upper respiratory infections.
Sneezing occurs when your sinuses naturally relieve themselves of irritants such as dust, pollen, or other allergens. Your nose acts as a filter that traps these irritants before they reach your lungs. Therefore, when you sneeze, your body immediately signals that irritants must be removed from the sinuses.
When a person develops an upper respiratory infection, they can experience a change in the normal sinus function. This can lead to sneezing and other symptoms of an upper respiratory infection, such as coughing and congestion.
