What Outdoor Plants Cause Allergies?

Outdoor plants cause allergies just as much as indoor plants. They can cause a range of allergic reactions from mild to severe, depending on the person and the plant. Allergic reactions to outdoor plants are usually caused by pollen, but some plants may also contain contact allergens that can cause skin rashes or other symptoms.

Types of Allergens

Outdoor plants can contain a variety of allergens, including pollen, spores, and contact allergens. Pollen is the most common allergen found in outdoor plants.

It is released into the air by certain flowers and trees and can be breathed in by people who are allergic to it. Spores from fungi such as mold may also be released into the air and inhaled by people who are sensitive to them. Contact allergens are found on certain plants which cause skin irritation when touched, such as poison ivy or nettles.

Common Allergenic Plants

Some of the most common outdoor plants that can cause allergies include flowering trees such as oak, birch, alder, cedar, chestnut and ash; grasses such as rye and timothy; weeds like ragweed; and molds like Alternaria. These types of plants release large amounts of pollen into the air during certain times of year which can trigger allergic reactions in some people.

Symptoms

The symptoms of an allergy to outdoor plants vary from person to person but typically include sneezing, itching eyes and nose, runny nose and congestion. Symptoms may also include wheezing or difficulty breathing if there is an asthma component to the allergy. In severe cases anaphylaxis could occur which could be life threatening if not treated promptly with epinephrine (EpiPen).

Prevention Tips

There are a few prevention tips for those who suffer from outdoor plant allergies:

  • Avoid being outdoors when pollen counts are high.
  • Wear a mask when mowing lawns or gardening.
  • Keep windows closed during peak pollen season.
  • Take antihistamines if needed.
  • Shower after spending time outdoors.

In conclusion, outdoor plants can cause serious allergic reactions in some people due to their pollens and contact allergens. Knowing what types of outdoor plants may trigger your allergies is important in order to avoid them or take precautions before coming into contact with them. Taking preventative measures such as wearing masks when gardening or avoiding being outside during peak pollen season can help reduce your allergy symptoms.
