What are allergies?
An ‘allergy’ is a sensitivity of your immune system to something that is ordinarily harmless. When your body reacts to the ‘allergen’ (foreign substance), you experience symptoms like sneezing, itchy, watery eyes, and a runny, stuffy nose. Typical allergens include pollen, pet dander, dust mites, and mould.
Outdoor: Hayfever and Seasonal Allergies
Seasonal allergies, commonly known as hayfever, are most prevalent during spring and early summer. For people with hayfever, symptoms come and go with the pollination seasons of certain trees and grasses. Pollen levels from these plants can vary day to day, depending upon several factors, including the weather. High pollen levels can, in turn, affect the severity of symptoms.
Indoor: Year-Round Allergies
Indoor allergies can occur any time of the year and are caused by allergens such as dust mites, mould spores, or pet dander.
