Managing Indoor Allergens During Cooler Months: Keep Symptoms at Bay

As temperatures drop and people spend more time indoors, allergy symptoms don’t always go away. For many, they actually get worse. While outdoor allergens like pollen decline, indoor triggers such as dust mites, pet dander, and mold become more concentrated in homes and workplaces.

“We often see patients who assume allergy season ends with fall, but indoor allergens can be just as disruptive,” says Dr. Nalini Packianathan, board-certified allergist at Schweiger Dermatology & Allergy in Northtown, NY.

If you or your child experience congestion, sneezing, or itchy eyes in the colder months, indoor allergies may be the reason. The good news is that simple changes at home, along with expert-guided treatment, can make a big difference.

Why Indoor Allergies Flare Up in Fall and Winter

Once windows are closed and heating systems turn on, allergen levels often build up indoors. Dust mites are especially problematic.

“Dust mites are one of the most common aeroallergens we worry about in colder months,” explains Dr. Packianathan. “Heating systems create a warm, humid microclimate indoors that’s perfect for dust mite growth.”

These microscopic bugs live in mattresses, pillows, carpets, and upholstered furniture, and are a major cause of sneezing, nasal congestion, and itchy eyes.

Other common indoor allergy triggers include:

• Pet dander, which lingers in the air and on surfaces
• Mold spores, especially in damp areas like bathrooms or basements
• Dry air and poor ventilation, which can make symptoms feel worse

“When patients understand what’s triggering their allergies, they can take real steps toward relief,” adds Dr. Packianathan.

Simple Tips to Reduce Indoor Allergy Triggers

While indoor allergens may be hard to eliminate completely, these simple changes can significantly reduce exposure:

• Wash bedding weekly in hot water (130°F or higher)
• Use allergen-proof covers for pillows and mattresses
• Avoid wall-to-wall carpeting and heavy drapes that trap dust
• Run a dehumidifier to keep indoor humidity below 50 percent
• Vacuum with a HEPA filter and dust with damp cloths
• Use an air purifier to reduce airborne allergens

“These changes can make a big difference in keeping allergy symptoms under control, especially during months when we’re indoors most of the time,” says Dr. Packianathan.

When to Consider Allergy Testing or Treatment

If your symptoms persist even after making changes at home, it may be time to speak with an allergy specialist. At Schweiger Dermatology & Allergy, we offer:

• In-office allergy testing to identify your specific triggers
• Personalized treatment plans based on your lifestyle and environment
• Immunotherapy, such as allergy shots or drops, to build long-term tolerance

“Allergy testing can identify all triggers, including dust mites,” says Dr. Packianathan. “Immunotherapy is a disease-modifying treatment that retrains the immune system to stop overreacting to allergens like pollen, dust mites, pet dander, and mold.”
