Hello. I know that when a person who has allergies gets an allergen like dust 
in their nose and starts sneezing, it's due to histamine being released by 
mast cells in their nose.  But people who don't have allergies also sneeze. My 
quesion is, is histamine involved in making healthy people without allergies 
sneeze?
