Definition of Allergies
Allergies, a common immune system response, occur when the body reacts to substances perceived as harmful, known as allergens. These allergens can vary widely and may include pollen, dust mites, pet dander, mold spores, and certain foods. The immune system, in its attempt to defend the body, releases chemicals like histamines, leading to allergic symptoms such as sneezing, itching, congestion, and more. Understanding the basics of allergic reactions sets the foundation for effective allergy management.
