Winter Allergies

Allergies and asthma don't take a winter holiday. Even during the cold months, common allergens are all around. And worse, allergies and asthma can be exacerbated by a holiday season full of alcohol, unhealthy foods, and poor sleep habits.

“Your immune system is run-down. When you’re tired, your immune system is tired, and you’re more sensitive to allergens,” says Denise Wood, the clinical director at the Advanced Allergy Solutions clinic in San Francisco.

Allergens Don’t Take a Holiday

During the colder months, when snow and rain cloud the air, it can be hard to imagine that common outdoor allergens like pollen could be swirling around. And for people living in snowy environments, springtime hay fever—the generic term for a collection of symptoms like sinus irritation, itchy eyes, and congestion caused by allergens known as allergic rhinitis—most likely won’t be a worry, says Wood.

However, for people living in warmer climates, there’s a price to pay for nicer weather.

Largely, if things are in bloom and trees retain their leaves, there’s a chance of pollen-induced allergies.

But with many people heading indoor for winter festivities, exposure to indoor allergens increases. For asthmatics sensitive to common indoor allergens, the winter months unfortunately don’t offer seasonal relief. 

In addition to common allergens, Christmas trees, fireplaces, and poor diet and sleep habits can contribute to asthma and allergies. While the pine scent of a Christmas tree is certainly evocative of the season, it may not be the best idea for people who are particularly sensitive. Ditto with fireplaces, which release smoke and pollutants into the air.

If possible, wash the tree outside and let it dry completely before bringing it inside. That tactic seems to help a majority of patients who have pollen allergies, Wood says. And make sure fireplaces are well ventilated. 

And when central heating is turned on and circulating air throughout a house, it’s also circulating things like dust, dust mites, and pet dander. If you’re particularly sensitive to dust or dander-induced asthma attacks, Wood recommends switching off the central heating and trying space heaters as an alternative, which won’t circulate allergens along with the hot air.

What You Eat Matters

Allergies are an inflammatory response to an allergen, and certain foods like sugar, dairy, and wheat can produce additional inflammatory responses that compound a reaction, Wood says. For asthmatics, preservatives and nitrates can be particularly irritating, she says.

In addition to certain foods weakening your allergy defenses, when you’re tired and have had perhaps one too many mugs of eggnog or hot cider, your immune system can be compromised and become more prone to a reaction.

“The combination of being run-down and eating a lot of food, [people are] more susceptible to getting that sinus infection,” Wood says.

While that doesn’t mean you should forgo the entire holiday spread, it does mean that if you’re suffering from a runny nose or itchy eyes, skipping the sugar-laced gingerbread house or second helping of iced cookies may be a good idea. You’ll save on tissue and will enjoy the holidays a bit more through clear eyes and without a ruby red nose.
