Question

When you go to a new place and suddenly you started sneezing, wheezing for no explained reason, and when you went away, your symptoms disappeared. Why it is so?

Answer 1

There are those of us who are sensitive to certain environmental pollutants. The aforementioned reaction may be the result of a localized allergy to mites, pollen, etc. Mast cells release substances like histamine and serotonin, which causes allergies.
