Allergic Rhinitis: Seasonal allergic rhinitis (more commonly known as hay fever) is mainly an allergy caused by outdoor allergens, such as tree, grass and weed pollens, as well as some mold spores. If you sneeze and have a runny or stuffy nose during the spring, summer or fall allergy seasons, you may have hay fever. Hay fever is the most common type of allergy problem, and symptoms include sneezing, itching, runny or stuffy nose, and red, watery eyes.

What causes my allergies to flare up in the spring? Pollen is the most likely cause. Your immune system has mistakenly learned to remember the pollen released by various plants as potentially harmful, and responds with the familiar allergic symptoms. Each species of plant releases pollen at about the same time every year. Trees are usually the first plants to release pollen, usually in the early spring. Grasses come next in the spring and early summer. Weeds generally release their pollen in late summer and fall. The specific types of pollen and the time of their release depends upon the local climate and varies around the country. People with seasonal rhinitis are often allergic to more than one type of pollen.

Exposure to animal dander (dead skin that is continually shed) as well as animal urine and saliva causes human allergic reactions to animals. These reactions can make asthma, rhinitis and/or eczema (atopic dermatitis) symptoms worse in some people. The dander, urine and saliva of feathered or furry animals such as cats, dogs, birds and rodents (hamsters, gerbils, mice etc.) can cause allergy symptoms. Exposure to other warm-blooded animals, such as horses or cattle, or to products made with feathers or down, may also cause allergy symptoms. A person can develop allergies with repeated exposure.
