Hay fever affects more than 35 million individuals in the U.S. Symptoms include sneezing, congestion, itchy eyes, stuffy or runny nose and scratchy throat.
Airborne pollens are exactly that, pollens that are transferred via the wind.
Plants with bright flowers and strong fragrances, such as roses, usually do not trigger allergic reactions. These plants have large waxy pollen that need a carrier such as birds, bees, or other insects to carry the pollen. On the other hand, many trees, grasses, and low-growing weeds rely on the wind to carry their pollen. Pollens that are small, light, and dry are well-suited for dissemination by wind. These pollens can travel several hundred miles.
