    You’ve got a problem with pollen. Do you know if the kind that bothers you comes from trees, and which ones to avoid?

    It’s a common cause of allergy symptoms, especially in the early spring. And it’s not just about the trees in your yard.

    Living With Severe Allergies

    Allergies affect more than 50 million people in the United States -- the poor souls who sniffle, sneeze, and get all clogged up when face to face with the allergen (or allergens) that set them off. For many, allergies are seasonal and mild, requiring nothing more than getting extra tissue or taking a decongestant occasionally. For others, the allergy is to a known food, and as long as they avoid the food, no problem. But for legions of others adults, allergies are so severe it interferes with...

    What to Know

    Tree pollens that trigger allergies tend to be very fine and powdery. The wind can carry them for miles.

    Inhaling even small amounts can trigger allergy symptoms.

    Trees that often set off allergies include:

    • Ash
    • Aspen
    • Beech
    • Birch
    • Box elder
    • Cedar
    • Cottonwood
    • Elm
    • Hickory
    • Mountain elder
    • Mulberry
    • Oak
    • Pecan
    • Willow

    People with tree pollen allergies sometimes assume that trees with colorful flowers -- like apple or cherry trees -- will trigger their symptoms. But flowering trees usually have bigger, stickier pollen that doesn't blow in the wind or cause symptoms.

    3 Things That Make It Worse

    1. Warm, windy days. Wind picks up dry pollen and sends it into the air. When it's cold or damp, pollen counts are usually lower.

    2. Certain fruits and vegetables. If you have nasal allergies to certain trees, you have a higher risk of allergic symptoms from some of these foods. For instance, if you're allergic to birch trees, you may get itchiness or swelling in your mouth or around your face after eating almonds, apples, carrots, celery, cherries, coriander, fennel, hazelnuts, kiwi, peaches, pears, or plums.

    3. Having trigger trees in your yard. How close you live to a tree makes a big difference. When one's in your own yard, it could expose you to 10 times as much pollen as a tree down the street.

    Tips to Manage Your Allergy

    Get tested. It's important to know which trees trigger your allergies. Once you do, you can figure out how to avoid their pollen.

    Avoid contact. It’s simple: Stay inside when pollen counts are high. Keep your windows shut. Wear a mask if you need to work outside.

    Remove trigger trees. If one in your yard clearly causes symptoms, prune back the branches to reduce the amount of pollen it releases. You could also take it out and replace it with one that’s less likely to cause allergies, like apple, cherry, dogwood, fir, or pine trees.

    Treat it. Medicine -- both OTC and prescription -- can ease or prevent allergy symptoms. Allergy shots and other forms of “immunotherapy” can also make a difference.
