For people living with Chronic Obstructive Pulmonary Disease (COPD), the air they breathe can have a direct and immediate impact on their overall health. COPD is a progressive lung disease—often including chronic bronchitis and emphysema—that makes it harder to breathe over time. Airflow becomes restricted due to lung damage, and even minor irritants can lead to flare-ups that cause symptoms like wheezing, coughing, shortness of breath, and increased mucus production.
As we move into allergy season, especially during May and June, COPD patients are more likely to experience flare-ups. While many people think of allergens as outdoor threats, they can easily enter—and your home may already be full of hidden triggers.
Lesley Williams, a Registered Respiratory Therapist at Apria with 35 years of experience, states, “Managing COPD begins at home—by recognizing and reducing everyday triggers, patients can create a safer environment that supports better breathing, fewer flare-ups, and a higher quality of life.”
COPD makes the lungs more sensitive to allergens and airborne irritants. When allergens enter the respiratory system, they can cause inflammation, flare-ups, and worsen breathing problems. Sometimes, this leads to hospital visits or a significant decline in quality of life. That’s why preventing exposure to triggers is just as crucial as managing symptoms.
Even if you’re careful about pollen exposure outside, it can still find its way through open windows, shoes, clothes, and pets. Once inside, it settles on home surfaces and in the air, making your home a hidden source of irritation.
In addition to pollen, many indoor elements can trigger COPD symptoms. Here are some common sources and how to manage them:
Tobacco smoke, wood-burning stoves, and even candles can irritate your lungs. Avoid smoking indoors and opt for flameless alternatives when possible.
Perfumes, cleaning products, and air fresheners may contain chemicals that inflame the airways. Choose fragrance-free or natural alternatives whenever possible.
Common cleaning agents, paints, and aerosol sprays release volatile organic compounds (VOCs) that can cause lung irritation. Use eco-friendly, low-VOC products and ventilate well when cleaning or renovating.
Soft materials can collect dust and allergens. Wash them regularly in hot water or limit them in frequently used home areas.
Even if your pet doesn’t shed much, their dander can trigger symptoms. Bathe and groom pets regularly and consider using pet-specific air purifiers.
Dust and dust mites can trigger inflammation in the airways. To reduce exposure, clean regularly with a HEPA-filter vacuum, wash bedding in hot water weekly, and use dust-mite-proof covers on pillows and mattresses.
Cockroach droppings and body parts can be potent allergens. Keep food sealed, clean up crumbs quickly, and use traps or professional pest control.
High humidity creates the perfect environment for mold and dust mites, two primary triggers for COPD. Use a dehumidifier to keep humidity levels between 30-50%. Be sure to clean damp areas like bathrooms and basements frequently.
COPD flare-ups are often caused by everyday triggers hiding in plain sight. But with a few adjustments to your environment and routine, you can breathe easier this allergy season. Creating a clean, allergen-aware home is one of the most effective steps to minimize flare-ups and protect your long-term health.
If you’re unsure which allergens might affect you, talk with your healthcare provider about home air quality assessments or allergy testing. Staying informed can make all the difference.
