Winter Allergens: The Forgotten Allergy Season for Some

As weather grows colder, allergens are often overlooked. Unfortunately, allergens are present year-round. There are no specific allergens that increase during the winter season, but there may still be allergens present in your home. Those who suffer from exposure to these indoor allergens may experience increased symptoms due to increased time spent indoors.

Indoor Allergens in the Winter

Winter allergies come from any allergens that get trapped inside your home. These airborne allergens may include dust, pet dander, and mold. Many people don’t realize that indoor air can actually be dirtier than outdoor air.


Dust can quickly collect on everything in your home during any time of the year. In the winter, dust collects quicker due to the decreased airflow throughout your home. With the windows closed, the dust doesn’t have anywhere else to go but collect on your surfaces and stay inside.

Pet Dander

If you have pet allergies and a pet, you understand that it is always allergy season in your home. Pet dander can be found on almost any indoor surface like bedding, clothing, and floors. Although this is a year-round occurrence, airborne pet dander allergens may increase in the winter.

During the winter, your pets may also be spending more time indoors. Not only will this give them the opportunity to leave more dander in your home, but they’re probably also spending more time cuddling with you.


Mold thrives in places with moisture like bathrooms, kitchens, and basements. Not all homes have mold, but those that do will be trapping the mold indoors during the winter months. In addition, the heat may contribute to the growth of mold, since mold thrives in wet and humid conditions.

Who May Be Affected by Winter Allergens?

Those at risk of experiencing allergy symptoms during the winter include those who are allergic to any indoor allergens, have those allergens present in their homes, and spend time indoors exposed to those allergens. In locations that do not have a very cold winter, allergens may not get trapped indoors as much as in colder climates.  

How to Manage Winter Allergens

If you suffer from allergy symptoms during the winter, consider using one of the following tips to manage indoor air allergens.

  • Wipe your feet when entering any indoor space from the outside. Wherever you go when you leave the house, you have the potential to track allergens indoors.
  • Dust regularly. If dust allergens are the issue, be sure to dust regularly to avoid dust gathering on surfaces over time.
  • Use allergy-specific bed products. To help with allergy symptoms at night, use allergy-specific bed products. These products include covers for your pillows, mattress, comforter, box spring, and more.
  • Use an air purifier. Air purifiers help to capture allergens including dust, pet dander, and mold from your indoor air.
  • Regularly wash any fabrics. Allergens can attach to fabrics such as your bedding, clothing, rugs, and towels. Regularly washing each of these will help to minimize the allergens present around your home.
