Here is a list of trees that are most likely to contribute to your seasonal allergy symptoms.
Birch Trees
Birch trees are deciduous trees with tall trunks and papery bark.
The color of the bark ranges from white to salmon to purple.
Birch trees can be found in nearly every state in the U.S. and grow mostly in cooler regions.
Birch trees release their pollen between January to April, depending on their location.
Oak trees vary in size and shape: from shrub-like to large, stately shade trees.
Oak trees produce acorns when pollinated.
Plants have both female and male reproductive systems.
Pollen contains the male reproductive cells (or gametes).
During early to late spring, many trees release a large amount of pollen.
Diagnosing a Tree Pollen Allergy
Trees often release pollen before other plants do.
If you experienceallergysymptoms early in the spring, you might have a tree pollen allergy.
Pollen counts are highest in the morning, peak about midday, and then gradually fall.
The lowest pollen counts are usually in the late afternoon to early evening.
To get a definitive diagnosis of tree pollen allergies, youll need to see a healthcare provider.
They can make a diagnosis throughallergy testing.
