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.
Home Remedies: Using Kleenex Anti-Viral tissues helps prevent the spread of viruses. No tissue? Sneeze into your upper sleeve, not your hands. You’ll be less likely to pass germs along.
Over-the-Counter Remedies: Some antihistamines (the sedating varieties) can help cut down on the sneeze reflex. But most experts advise you to leave this fairly innocuous symptom untreated.
