Understanding Allergies and Their Triggers
What Are Allergies?
Allergies occur when the immune system reacts to a foreign substance—such as pollen, pet dander, or dust mites—that doesn’t cause a reaction in most people. These substances are known as allergens. For some, allergies can trigger severe symptoms like asthma attacks, while others might experience milder reactions such as a runny nose or itchy skin.
Common Allergens
- Pollen: This is a fine powder produced by trees, flowers, grasses, and weeds to fertilize other plants of the same species. Inhaling pollen can cause sneezing, congestion, and itchy eyes.
- Dust Mites: These tiny creatures thrive in warm, humid environments and are found in bedding, carpets, and upholstered furniture. They can trigger asthma and other allergic reactions.
- Pet Dander: Proteins found in a pet’s skin cells, urine, and saliva can cause allergic reactions. Pet hair itself is not an allergen, but it can collect dander and other allergens like dust and pollen.
- Mold: Mold spores can float through the air and, when inhaled, can cause allergic reactions. Mold thrives in damp, humid environments.
- Tobacco Smoke: Secondhand smoke contains numerous chemicals that can cause allergic reactions and exacerbate respiratory conditions.
- Volatile Organic Compounds (VOCs): These compounds are emitted as gases from certain solids or liquids, including household products like paints, varnishes, and cleaning supplies. VOCs can cause allergic reactions and other health issues.
These allergens can enter your home through various means, including open windows, and doors, and on clothing or pets.
Allergy Symptoms
Common allergy symptoms include:
- Sneezing
- Runny or stuffy nose
- Watery, itchy eyes
- Itchy skin or rash
