The holidays are meant to be joyful—but for many Houstonians, the season also brings a wave of sneezing, itchy eyes, and congestion. Christmas allergies are more common than you might think, and with Houston’s unique climate, indoor decorations, and seasonal changes, symptoms can flare quickly.
This guide breaks down the biggest holiday allergy triggers, why they happen, and how to keep symptoms under control so you can enjoy the season comfortably.
Why Christmas Allergies Are So Common
During the holidays, we’re exposed to more indoor allergens, new decorations, and environments we don’t typically encounter year-round. Combine that with Houston’s fluctuating winter weather, and you get the perfect recipe for Christmas allergies.
Common symptoms include:
- Sneezing and a runny nose
- Post-nasal drip
- Watery, itchy eyes
- Cough or wheezing
- Headaches or sinus pressure
Top Holiday Allergy Triggers
- Christmas Trees (Real & Artificial)
Real trees can carry mold spores, and pollen—all of which can trigger allergic reactions. Mold grows faster when a tree sits inside a warm Houston home.
Artificial trees can also cause flare-ups if they’ve been stored all year in dusty attics or garages.
Combat the trigger:
- Rinse real trees with water before bringing them inside
- Allow trees to dry thoroughly outdoors
- Wipe down artificial trees and ornaments
- Use an air purifier in the room where the tree is displayed
- Holiday Decorations & Dust
Garlands, wreaths, lights, and ornaments collect dust and sometimes mold when stored. When you unpack them, these allergens become airborne.
Combat the trigger:
- Clean stored decorations before use
- Replace old fabric decor that’s hard to wash
- Store items in airtight containers for the future
- Scented Candles & Fragranced Decor
Holiday-scented candles, room sprays, and potpourri can irritate the airways—even if you’re not technically “allergic.” Many contain synthetic fragrances that aggravate Christmas allergies for sensitive individuals.
Combat the trigger:
- Choose unscented candles
- Opt for natural essential oils if tolerated
- Improve ventilation during gatherings
- Pet Allergens
When family visits for the holidays, they often bring pets. Even if the pet doesn’t stay long, dander residue can trigger reactions.
Combat the trigger:
- Vacuum with a HEPA filter
- Use air purifiers in common areas
- Ask guests to keep pets off furniture, if possible
- Holiday Foods
Seasonal dishes often include nuts, dairy, shellfish, or spices that can trigger food allergies. Holiday buffets also increase the risk of cross-contamination.
Combat the trigger:
- Ask about ingredients before eating
- Carry antihistamines or epinephrine if prescribed
- Inform hosts of any food allergies in advance
How to Prevent Holiday Allergy Flare-Ups
- Keep Indoor Air Clean
Use HEPA filters, vacuum regularly, and change HVAC filters—especially during holiday gatherings.
- Manage Mold Growth
Houston’s humidity doesn’t completely disappear in winter. Keep indoor moisture below 50% and watch for mold near windows and decorations.
- Start or Adjust Allergy Treatment Plans
If you suffer from chronic Houston holiday allergies, an allergist can create a personalized plan that may include medications, avoidance strategies, or immunotherapy.
- Schedule an Allergy Test
If you’re unsure what’s causing symptoms, an allergy test from your local allergist can provide clarity and help guide long-term prevention.
