Spring is the time of year that we normally think of when it comes to seasonal allergies. As the trees start to bloom and the pollen gets airborne, allergy sufferers begin their annual ritual of sniffling and sneezing. Each year, 35 million Americans fall prey to seasonal allergic rhinitis, more commonly known as hay fever.
Although there is no magical cure for spring allergies, there are a number of ways to combat them, from medication to household habits.
What causes spring allergies?
The biggest spring allergy trigger is pollen -- tiny grains released into the air by trees, grasses, and weeds for the purpose of fertilizing other plants. When pollen grains get into the nose of someone who’s allergic, they send the immune system into overdrive.
The immune system, mistakenly seeing the pollen as foreign invaders, releases antibodies -- substances that normally identify and attack bacteria, viruses, and other illness-causing organisms. The antibodies attack the allergens, which leads to the release of chemicals called histamines into the blood. Histamines trigger the runny nose, itchy eyes, and other symptoms of allergies.
Pollen can travel for miles, spreading a path of misery for allergy sufferers along the way. The higher the pollen count, the greater the misery. The pollen count measures the amount of allergens in the air in grains per cubic meter. You can find out the daily pollen count in your area by watching your local weather forecast or by visiting the NAB: Pollen & Mold Counts page on the American Academy of Allergy, Asthma and Immunology’s web site.
Here are some of the biggest spring allergy offenders:
Alder, Ash, Aspen, Beech, Box elder, Cedar, Cottonwood, Cypress, Elm, Hickory, Juniper
Maple, Mulberry, Oak, Olive, Palm, Pine, Poplar, Sycamore, Willow
Grasses and weeds
Bermuda, Fescue, Johnson, June, Orchard, Perennial rye, Redtop, Saltgrass, Sweet vernal, Timothy
Allergy symptoms tend to be particularly high on breezy days when the wind picks up pollen and carries it through the air. Rainy days, on the other hand, cause a drop in the pollen counts because the rain washes away the allergens.
