Why is my hayfever allergy flaring up in winter?

Many people associate hayfever, or allergic rhinitis, with spring when airborne pollens are at their peak but allergic rhinitis can occur in any season or all‐year round depending on the triggers. If your allergy symptoms are flaring up in the colder months it might be due to a number of reasons:

  1. Dust mites, moulds and animal dander – Allergic rhinitis can be caused by a reaction to allergens around the home that aren’t typically seasonal and are present all year round. This is known as perennial allergic rhinitis.
  2. An earlier hayfever season – The start of the hayfever season can vary according to location and from one year to another. Typically trees pollinate at the end of winter and beginning of spring although sometimes trees will start pollinating earlier because of a mild winter or a wet autumn season. There is also evidence to suggest that global climate change is causing an earlier and longer pollen season.
  3. Winter pollinators – The White Cypress (Murray) pine produces highly allergenic pollen from late July through to the end of August. It is found across Australia south of the Tropic of Capricorn. There are also many species of Casuarina and Australian Oak trees which produce pollen all year round and may cause sniffling and sneezing at any time of year. To find other plants in your region that may be causing your winter hayfever symptoms, check out the Telfast Seasonal Allergen Guide.
