(CNN) - Fall brings cool weather, football and colorful changes in leaves. It also brings misery to millions of seasonal allergy sufferers.
Ragweed is the culprit for Anne Corbitt, who loves to walk, hike, camp and tailgate in the autumn of the year.
"Sometimes that's been really tough because of my allergies, because just standing outside can make them happen," she said.
Mold spores, which grow on fallen leaves, also are a problem.
"It's very common for people who have year-round allergies to have worsening of their symptoms during the fall ... as well as spring," said Dr. Alan Redding, an allergy specialist.
He tells patients ways they can help themselves, such as buying HEPA air filters, using a saline nasal spray and avoiding raking or bagging leaves or if they do, to wear a mask. It also is a good idea to reserve outdoor activity for later in the day.
While these tips may help minor symptoms, Redding says it's best to see a board-certified allergist if the symptoms are more severe, as in Corbitt's case.
She started a series of allergy shots almost two years ago – the immunotherapy works by gradually reducing a person's sensitivity to their allergens.
It enables her and others to fully enjoy their outdoor activities.
