Ah, fall. The perfect time to get outside for long walks in the neighborhood, hikes in the hills, and autumn gardening.
But that "ah" can quickly become "ah-choo" if you're one of the 36 million Americans with seasonal allergy problems. The runny nose, itchy eyes, and congestion -- all typical fall allergy symptoms -- can slow you down and make you miserable.
We all know people who blame the weather for their achy joints, killer headaches, and many other health woes. But proving these claims has been a bit more elusive.
In recent years, however, scientists have become increasingly interested in attempting to understand just how various weather extremes and changing patterns affect our health. Many experts say that weather does account for some adverse health symptoms.

While there have been no dramatic advances recently in allergy treatment, experts say if you are allergy-prone, you can take a number of steps to minimize the misery.
1. Know Your Allergy Triggers
Triggers, or allergens, can vary by region of the country, but two main culprits are to blame for many fall seasonal allergy problems, experts say.
Ragweed and other weed pollens. Ragweed is a stubborn plant and grows easily in fields, along roadsides, and in vacant lots. A plant can produce a billion pollen grains in a season, and the grains can travel up to 400 miles because they are so lightweight.
Molds. Outdoor molds grow in heavy vegetation, hay and straw, and are found in raked leaves. Outdoor molds increase after rain, too.
Predicting how bad an allergy season will be is an inexact science, but there are some general links with weather, says Gary Rachelefsky, MD, a staff allergist at Santa Monica-UCLA Medical Center and Orthopaedic Hospital. "Usually when there is more rain, there is more pollen," he says. Outdoor mold can increase, too, with more moisture. So if you live in an area struck by flooding or heavy rains in the spring or summer, you can probably expect a worse-than-usual allergy season.
