I read that in most cases, constant sneezing is a symptom of a common allergy called hay fever. Plant pollen provides the irritation, and although the name hay fever may suggest that hay or newly mowed grass is the culprit, this may not always be the case. Sufferers may be allergic to a number of different pollens, or perhaps just one. So it is easy to understand why hay-fever sufferers dread seasons when strong, dry winds blow for days. Once the nasal passages are irritated and continuous sneezing begins, the slightest dust particle that normally would not cause irritation seems to start the victim on another bout of sneezing.
