A
Grass Allergy: What Causes It?
One
of the most prevalent allergies in the United States, a grass allergy
is also one of the most exasperating afflictions. For the estimated
50 million Americans who suffer from all types of allergies (according
to the Asthma and Allergy Foundation of America), a grass allergy
can be frustrating and can even hold them back from living their
life to the fullest. Further, many people with a grass allergy also
suffer from other types of allergies. With the itchy eyes, runny/stuffy
nose, headaches, and other symptoms, living with a grass allergy
alone can be unbearable, let alone if you also suffer from indoor
allergies. Unlike a bacteria or virus, in which your immune system
attacks a malicious outside matter, a grass allergy is caused by
the body fighting a normally harmless substance.
Some
common grasses that can trigger a grass allergy include:
- Timothy
- Johnson
- Bermuda
- Kentucky bluegrass
- Orchard
- Sweet vernal
As
the name suggests, a grass allergy is triggered by pollen, specifically
from grass. Because of this, a grass allergy is usually worse in
the spring and summer months, when pollen counts are higher. However,
the severity of a grass allergy is impacted by the temperature,
humidity, and weather. For example, when it rains, pollen counts
are reduced because they are washed away and unable to float on
the air currents as well as on dry air. Further, pollen counts
are generally lower in the late afternoon. However, if you or your
neighbor cuts the lawn, your grass allergy may be triggered by the
pollen released by the lawnmower.
Once
you understand the causes of a grass allergy, you can take steps
to avoid the runny nose, itchy eyes, and other symptoms.
