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.
Summer is ending, you’re heading into fall. But you’re still sneezing and sniffling all day and into the night. What’s going on?
Odds are you’re among the 10% to 30% of Americans who suffer from hay fever, or allergic rhinitis. And most cases of hay fever are caused by an allergy to fall pollen from plants belonging to the genus Ambrosia -- more commonly known as ragweed.
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:
Grasses and weeds
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.
What are the symptoms of spring allergies?
The symptoms of spring allergies include:
Itchy eyes and nose
Dark circles under the eyes
Airborne allergens also can trigger asthma, a condition in which the airways narrow, making breathing difficult and leading to coughing, wheezing, and shortness of breath.
How are spring allergies diagnosed?
If you’ve never been formally diagnosed with spring allergies but you notice that your eyes and nose are itchy and runny during the spring months, see your doctor. Your doctor may refer you to an allergist for tests.
The allergy specialist may do a skin test, which involves injecting a tiny sample of a diluted allergen just under the skin of your arm or back. If you’re allergic to the substance, a small red bump (called a wheal or hive) will form. Another diagnostic option is the radioallergosorbent test or RAST. RAST is a blood test that detects antibody levels to a particular allergen. Just because you are sensitive to a particular allergen on a test, though, doesn’t mean that you’ll necessarily start sneezing and coughing when you come into contact with it.
