The holiday season brings joy and festive decorations—but for some, it also brings unexpected allergy symptoms. Many of the decorations we look forward to unpacking during the holiday season live in attics, basements, and garages during the rest of the year. They can harbor allergens like dust, mold, and fragrances, turning the holidays into a time of sneezing and discomfort. Let’s look at how decorations can trigger allergies and how you can make your home more comfortable during the holidays.

Common Holiday Décor Allergens

Dust and Dust Mites

Decorations stored in dusty spaces tend to accumulate particles over time. When decorations are unpacked, dust is stirred up, which can trigger allergies, especially for those sensitive to dust mites.

Mold Spores

Garages, basements, and attics are prone to dampness, making them perfect environments for mold growth. Live greenery like Christmas trees and wreaths can also harbor mold, releasing spores into the air and causing symptoms such as coughing, congestion, and itchy eyes.

Fragrances and Scented Items

Holiday candles and potpourri often include synthetic fragrances and common irritants. Some can trigger headaches, sinus issues, or worsen asthma symptoms.

Pet Dander and Fur

Decorations can collect pet dander over time. Even if you don’t have a pet, dander can still make its way into your home by way of hand-me-down décor and secondhand items.

Pollen from Live Trees

Pine trees may bring pollen indoors. Trees grown outdoors often collect pollen from other plants, which can linger and trigger allergy symptoms.

How to Minimize Holiday Decoration Allergens

Clean Decorations Before Use

Wipe down decorations with a damp cloth to remove dust and vacuum ornaments, garlands, and artificial trees. For items like wreaths and garlands, give them a good shake outdoors.

Consider Artificial Trees

Artificial trees don’t contain pollen or bring in outdoor mold, making them a better option for those sensitive to allergens. Ensure you clean them before use and store them in a tightly sealed bag or box after the holidays.

Use Natural Scents

Choose unscented or naturally scented candles with essential oils instead of synthetic ones. For a flameless option, use a small essential oil diffuser to create festive scents without triggering respiratory issues.

Clean Décor Before Storing

When it’s time to pack away decorations, consider wrapping them in plastic or vacuum-sealed bags to keep them fresh and dust-free for next season.

Use Proper Storage

Use airtight containers for decorations to keep out dust and pests, and store them in a dry place to prevent mold growth. A dehumidifier in storage areas can also help keep moisture levels low, reducing the risk of mold buildup.


With a little preparation and some mindful choices, you can keep your holiday decorations from turning into an allergy trigger. You’ll create a safer, more allergy-friendly environment by carefully cleaning decorations and storing décor. These minor adjustments can help you enjoy a healthier, more joyful holiday season.
