Most of us spend 80–90% of our time indoors—especially at home. For
people with asthma, the home can be full of
hidden triggers that make asthma symptoms worse: dust mites,
mold, scented products, or dry heating air in winter.
In this article, you’ll learn how to create a space that supports your
lungs, reduces inflammation, and helps you breathe easier.

Some indoor exposures are more likely to trigger or worsen asthma
symptoms:
-
Dust mites:
found in bedding, carpets, and upholstered furniture
-
Mold: especially in damp areas like bathrooms or
basements
-
Pet dander:
even from “hypoallergenic” pets
-
Fragrances & cleaning products:
scented candles, sprays, air fresheners
-
Tobacco smoke & wood stoves:
strong airway irritants
-
Dry air:
especially in heated rooms during winter
Humidity: Keep between 40–60%. Too dry or too humid air can
worsen symptoms.
Temperature: Ideal indoor temp is 18–21 °C (64–70 °F),
especially in bedrooms.
Air purifiers: Use HEPA-filter devices to reduce dust,
pollen, and dander.
A clean and low-irritant home can boost the effects of your
medication. If you’re using inhaled corticosteroids (see
Why Corticosteroids Play a Key Role in Asthma Treatment) or other long-term medication (
Asthma Medications & Inhalers – What Really Helps), your environment can make a big difference in how often you
experience asthma symptoms.
An asthma-friendly home doesn’t need to be sterile or clinical. It
just needs thoughtful adjustments. By minimizing triggers, improving
ventilation, and tracking how your body reacts, you can make your home
a place that supports your breathing—not one that makes it harder.
Regular symptom tracking helps you recognize what works—so that your
home becomes your strongest ally in living well with asthma.
