This annual report can help you manage your seasonal allergies no matter where you live. With the right treatment and by reducing contact with pollen, you can feel better and improve your quality of life.

“For more than 50 years, the prevalence of allergic diseases has risen and it’s no coincidence that during the same time, pollen seasons have become stronger and longer due to warmer temperatures,” says Kenneth Mendez, AAFA CEO and president. “The Allergy Capitals report helps raise awareness about the impact of seasonal allergies, how people can prepare and start proper treatment. Local communities can also use the report as a tool to identify how to better meet the needs of their residents living with allergies and allergic asthma.”

What Are the Symptoms of Seasonal Allergies?

Do you get allergy symptoms in the early spring when trees release pollen? Or do you sneeze or get a runny nose during the late summer or early fall? If so, you may have seasonal allergies.

Seasonal allergies are known as seasonal allergic rhinitis. It’s commonly called “hay fever.” If you have pollen allergies, seasonal allergy symptoms appear during the time of year when pollen counts are high.

The symptoms of seasonal allergic rhinitis are:

  • Itching in the nose and eyes
  • Sneezing
  • Stuffy nose (congestion)
  • Runny nose
  • Mucus (phlegm) in the throat (postnasal drip)

If you have allergic asthma, you may also have asthma symptoms when pollen counts are high.

What Plants Cause Pollen Allergy Symptoms?

Tree pollen causes the most spring allergies. In some states, tree pollen can appear as early as January and stay through July. Weed pollen is common in the fall. Ragweed pollen causes the most fall allergies, affecting as many as 23 million people.

How Do You Treat Seasonal Allergies?

A board-certified allergist can help you come up with a plan to manage seasonal allergy symptoms. Allergy treatment options include:

  • Allergy medicines, such as antihistamines
  • Nasal corticosteroid sprays
  • Immunotherapy – allergy shots or tablets

You can also take steps to manage allergy symptoms by:

  • Reducing your contact with pollen 
  • Seeing a board-certified allergist for a treatment plan
  • Starting allergy treatment before the spring or fall seasons begin
SPRING ALLERGY TIP: Keep your windows closed and remove your shoes before entering your home to cut down how much pollen gets inside your home. More pollen allergy tips available at from @aafanational
