Welcome to our Breathe Easier in 2026 series! To start our breathe easier this winter series, let’s talk about your home. Have you noticed your allergy and asthma symptoms in winter worsening? It could be your house. Here are a few asthma and allergy triggers that are definitely worse in winter when your home is closed up and everyone is inside more.

Dry Air: Dry air can exacerbate asthma symptoms in winter by drying out your airways and lessening the moisturizing mucous layer that helps prevent an irritated throat and airway. To avoid this you can get a humidifier. It’s important to make sure you measure the level of humidity in your home. You want to keep it between 30-50%. This is a helpful level for adding moisture to the air and your airways when you breathe. Clean your humidifier frequently to avoid any mold or bacteria build-up.

Dust Mites: A closed-up home and heavier winter blankets can lead to an increase in dust mites. To keep them at bay, be sure to vacuum frequently and wash bedding in hot water. Consider a mattress cover too.

Pet Dander: In the spring, summer and fall your pets are (probably) outside more. In winter they, like the rest of us, are spending more time indoors, which means there will be more pet dander. Again, be sure to vacuum frequently and wash your pets’ bedding as well.

Finally, smoke and scents from candles can also make your asthma and allergy symptoms worse. Use an air purifier and HEPA filters to help as much as possible with cleaning the air. Consider an electric or gas fireplace instead of wood and avoid strongly scented candles.
