Warmer weather may feel good after a long, cold winter, but spring can be
rough on the nose and eyes. That's because hay fever, a seasonal allergy to
pollen, kicks in just as the sunnier days arrive. Never been near a bale of
hay, you say? You may still have hay fever, caused by the pollen from a variety
of trees, grasses, and weeds. The allergy's hallmarks-stuffy nose, watery eyes,
and fatigue-are a minor annoyance for some and bring full-blown misery to
Hay fever is not the only kind of spring allergy, but it is the most common.
As many as 50 million people in the United States have allergies -- and nearly
36 million of them have hay fever, says the American Academy of Allergy, Asthma
& Immunology (AAAAI).

Don't settle for all that sniffling, sneezing, and teariness. Work with a
doctor to find out what's causing your allergies. Hay fever treatments are
plentiful, including over-the-counter products, prescription drugs, and allergy
shots. With proper care, "most everybody can get through the season without
a whole lot of distress," agrees Larry Williams, MD, of the pediatric
allergy and immunology division of Duke University Medical Center.

The ABCs of Allergens
Allergies are classified by their source (such as food allergies) or the
part of the body they affect (such as skin allergies). Some allergies last all
year, including those to food, medicines, latex, dust mites, insect stings, and
animal dander. Other allergies, like hay fever, are seasonal. That's because
from spring through fall, plants reproduce by spreading pollen through the air.
In people with hay fever, pollen irritates the immune system, triggering a host
of allergy symptoms.
Nasal allergies, including hay fever, can irritate the eyes, nose, roof of
the mouth, and throat. Top culprits include:
Animal dander. Dead skin cells from animals.
Dust mites. Microscopic insects that live in household
dust, even in tidy homes. "Dust mites have to have conditions of warmth and
humidity" to thrive, says Williams.
Mold spores from fungi. Spores that thrive indoors in damp
areas, such as basements and bathrooms. They also gather outside in warm
climates and in leaf piles.
Pollen. A fine, powdery substance released by trees and
plants, including ragweed, grasses, and, of course, hay. Flowering plants, such
as roses, usually don't cause allergy symptoms. Their pollen is too large to be
carried by wind.
False irritants. Tobacco smoke and perfumes can irritate
the eyes, nose, and throat, but they're not allergens.
