Your Cold and Flu Symptoms, Explained
The Symptom: Sneezing
What it means: Your body is expelling bacteria and other particles with a sudden, involuntary burst of air. Don’t suppress a sneeze, as your body is trying to evict the irritants.
When to worry: Almost never, but if sneezing interferes with your life or persists after other symptoms are gone, talk to your doctor to find out if an allergy might be the cause.
