exposure to allergens

Exposure to allergens involves coming into contact with substances that your immune system mistakenly identifies as harmful. These can include pollen, dust mites, pet dander, certain foods, or insect stings. When exposed, your body may react defensively, releasing chemicals like histamine that cause allergy symptoms such as sneezing, itching, or swelling. The level of exposure and your sensitivity determine the severity of these reactions. Managing exposure—by avoiding known triggers or reducing contact—can help prevent or lessen allergic responses.
