What is Pollen? - Pollen Facts

Pollen: Facts About This Most Common Allergen

What is pollen?
Trees, weeds, plants, and grasses release small reproductive cells called pollen, which cause allergic reactions for millions of people. Most pollen are light enough to be windblown and are found everywhere, both indoors and out.

Some Facts About Pollen
Weeds, grass, and trees all produce a great deal of pollen. The most prolific producer of pollen is called ragweed. Ragweed is estimated to cause 75% of all pollen allergies. Pollen allergies are also caused by a variety of weeds, some varieties of grasses like Timothy grass and Bermuda grass, and also some trees.

An estimated 35 million Americans suffer from pollen allergies - or about 1 in 7.

People also commonly refer to pollen allergies as "seasonal allergic rhinitis," "hay fever," or "pollinosis."

Common symptoms of pollen allergy include:

  • Repeated or prolonged sneezing
  • Stuffy and watery nose
  • Swelling, itchy eyes
  • Itchy nose, throat, and mouth
  • Headaches and sore throat
  • Difficulty sleeping at night due to trouble breathing

These symptoms can get more severe if experienced year after year, leading to chronic sinusitis, headaches and ear problems, or asthma.

What can be done to decrease exposure to pollen?

Pollen can be difficult to avoid, since during allergy season, it's everywhere. Even if it were practical to stay inside all the time, pollen can still find its way indoors. But, there are a few steps you can take to reduce your exposure to pollen and relieve your pollen allergy symptoms.

  1. Avoid outdoor activities in the morning, between 5 to 10 a.m. It's also good to avoid being outside on dry and breezy days. The best time to go outside is in late afternoon or after a heavy rain. Of course, it's best to go outside as little as possible.
  2. After being outdoors, shower and change your clothes, since pollen sticks to clothing, skin, and hair. It's also a good idea to wash your hair daily, since pollen collects in your hair and can be transferred to your pillow.
  3. Don't forget about your pet! Your pet also transports pollen into your home, so a frequent bath for your pet will help control pollen inside the house.
  4. Use HEPA air purifiers to remove microscopic pollen particles from the air in the home, especially in the bedroom. Windborne pollen particles are always coming inside, but a HEPA air purifier will ensure that your indoor air stays clean. You'll have a safe haven from pollen allergies, at least inside your home.
  5. Close windows and use air-conditioning during pollen season. When windows are open, use filter screens to allow fresh filtered air into your home and keep airborne particles out. Use vent filters to keep any pollen particles from recirculating inside your home.
  6. Wear a high-quality protective mask for outdoor activities. Using a HEPA mask while doing yard work can make your outside chores much easier.
  7. Vacuum frequently with a HEPA filtered vacuum cleaner that removes and permanently traps airborne allergens.
