Ragweed, Allergic Rhinitis and
August 15th marks the beginning of Ragweed
Season. A stubborn, prolific plant, pollen released from ragweed is the airborne
allergen most responsible for the onslaught of allergy symptoms. It is found
along roadsides, vacant lots, fields and almost any other sunny spot. Ragweed
blooms from mid-August to October and is most prevalent throughout the Northeast
and Midwest, although some form of ragweed allergens are prevalent in all areas
of the United States. Each ragweed plant produces one billion pollen grains per
average season, and because they are especially small and light, can travel up
to 400 miles.
So if you notice that you’re sneezing more,
your eyes are tearing up and you’re reaching for the tissue box, you’re not
alone. You likely are one of the 35.9 million Americans who suffer from seasonal
rhinitis (hayfever), which is triggered by ragweed.
After being exposed to ragweed pollen, people
with allergies will often experience sneezing, a runny nose, and swollen, itchy,
watery eyes. The AAAAI reports that 80% of patients with seasonal allergies also
experience sleep problems, which can lead to fatigue, loss of concentration and
poor performance at school and work. Lost work and school days, medications and
physician office visits related to allergic rhinitis total more than $3 billion
annually in the United States.
