Are Allergies Only Found in Pollens?

Hay fever is also known as seasonal allergic rhinitis, because the symptoms appear only when it is pollen season. Hay fever originally only referred to allergies caused by grass pollens, but the term is now also used to describe the symptoms of rhinitis (inflammation of the mucous membrane inside the nose).

Where are allergens naturally found?

Allergens can be found in a variety of sources, such as dust mite excretion, pollen, pet dander, or even royal jelly. Food allergies are not as common as food sensitivity, but some foods such as peanuts (a legume), nuts, seafood and shellfish are the cause of serious allergies in many people.

Can allergies be in the air?

You know the feeling: You turn on the air conditioning on a hot summer day and suddenly find yourself sniffling, coughing, or sneezing. You wonder to yourself, “Could I be allergic to the AC?” The short answer is no. However, you can be allergic to the quality of the air circulating through your air conditioning unit.
