What Are Winter Allergies

Winter Allergy: Causes, Symptoms & Prevention | Winter Ready with Max

Many people think of allergies as seasonal, caused by grass, tree and ragweed pollen. Truth is, seasonal allergies can occur nearly year-round as trees release pollen in the spring, grasses in the summertime, and weeds go to work in the fall. And if you live in a warm climate, you might experience allergies in winter because some plants may not go dormant. For example, people who live in the Southwestern United States Texas, Oklahoma, Arizona, New Mexico and Missouri may experience whats called cedar fever if exposed to the Ashe Juniper tree during winter months.

If tree, grass and weed exposure trigger allergies in spring, summer and fall, then what could trigger allergy symptoms in wintertime? Winter allergies are less likely to be caused by outdoor triggers instead, they are triggered by exposure to allergens inside your home or office.

What’s Your Winter Allergies Risk

It hardly seems fair, but if you’re prone to summer allergies, chances are you’re at risk for allergies when the weather turns cold, too.

The reason is simple: Many of those warm weather irritants are around all year, like pet dander, mold, and mildew. And once you settle indoors for the chilly holiday season — the windows closed, the heater on — your exposure to these allergens spikes, says Asriani Chiu, MD, associate professor of pediatrics and medicine , at the College of Wisconsin.

The best way to handle winter allergies is to understand what’s triggering them and why. To help you do that, WebMD went to the experts and got their tips on what causes the allergies of winter, and how you can take control.

Tips For Combating Winter Allergies

If you are perpetually stuffy, have itchy/watery eyes, postnasal drip, and pressure in your head during winter, you might suffer from what is often referred to as winter allergies. Those allergic to weed, grass, or tree pollens might get some relief during the colder months, but there are indoor allergens present year-round that cause the same miserable symptoms. During these colder months, we often spend more time indoors with little ventilation and are exposed to more indoor allergens like mold, dust mites, cockroaches, and animal dander.

Here are some tips to help those suffering from winter allergies find some relief:

Winter is also a time when various viral illnesses are spreading. Respiratory illnesses can be especially dangerous for people with asthma. Remember to get your annual flu shot, increase hand hygiene, and avoid contact with sick individuals. Because symptoms of viral illness can be similar to allergic symptoms, it is sometimes difficult to distinguish between a cold or allergies. Remember that viral symptoms typically last between 10-14 days, whereas allergic symptoms can be prolonged. Additionally, viruses will often cause fevers, decreased appetite, and muscle aches, which are generally not caused by allergies.

Why Does Cold Weather Cause Sinus Issues

Cold weather can cause ear, nose and throat issues, but the temperature is not usually the main problem. Winter sees the spread of many viruses that may lead to infections in the sinuses, throat and ears. For allergy sufferers, being close to allergens for long periods causes sinus inflammation and subsequent ENT problems. If your symptoms clear within around 10 days, you probably had a cold or viral infection. When symptoms extend for longer periods, this can indicate allergy issues.

Winter Allergies Vs Colds

Cold and winter allergy symptoms can feel very similar, making it difficult to distinguish one from the other.

It is possible to develop allergies at any age or even to become allergic to the same substances in the same house after years of no reaction. The fact that a person has not previously had allergies does not necessarily mean their symptoms are from a cold.

Symptoms that last longer than a few weeks are usually the result of allergies. Symptoms that appear suddenly, after weeks or months in the same home, may be from a cold, especially if a person does not have a history of allergies.

There are some symptoms that can help distinguish allergies from a cold:

  • Colds can cause a fever, but airborne allergens will not change a personâs body temperature.
  • A cold may cause aches and pains, while allergies typically do not.
  • Sore throat is common with colds, but it occurs less frequently with allergies.
  • A person with a cold may feel chest pressure. By contrast, only people with asthma who have allergies typically report chest pain.
  • Coughs are more common with colds, although they can also occur with allergies.
  • Colds go away on their own. Allergies may only self-resolve when the weather changes, and a person spends more time outside.
  • Colds typically do not cause itchy rashes or eyes, whereas allergies often do.

How Do I Get Rid Of Winter Allergies

With some effort and attention, there are many ways to manage winter allergies and limit your exposure to specific triggers.

What You Can Do To Help Prevent Winter Allergies

How to minimize your winter, indoor allergy symptoms

Another major issue for people with winter allergies who live in colder climates is that the cold-weather lifestyle can turn a simple allergic reaction into something much worse. When you turn up the heat inside your home, for instance, your indoor air becomes much drier. This drier air can lead to dry noses, nosebleeds, and skin cracking which, in turn, boosts infection rates of secondary viral infection when a persons nasal passages are already inflamed from allergies.

It may not be possible to eliminate winter allergies entirely, but you can reduce exposure to allergens and neutralize their threat within your home. Here are some tips to help those suffering from winter allergies find some relief:

7 Surprising Winter Allergies

Dust is everywhere. Dust contains skin flakes and hair from people and pets, tracked-in dirt, clothing fibers, crumbs, and insect parts. Carpets, furniture, window treatments, and bedding are dust catchers. Filters in your HVAC ducts get dirty or clogged, poorly sealed windows allow pollen and dirt in, and vacuuming releases dust into the air.

Dust mites feed on the very things that make up dust, such as skin cells, insect parts and animal dander. They are present in almost every home, lurking in bedding, furniture, and carpets. Their feces contain digestive enzymes that allow them to get energy from their waste, but this enzyme can be a cocktail of allergens for humans.

Mold is also lurking indoors. It thrives in dark, moist places like bathrooms, basements and under sinks. Mold spores float through the air and are found even if conditions arent favorable. In the right conditions, they will grow on fabric, paper, wood, glass, and plastic.

  • Extra moisturizing use heavy lotion/oil and wear socks overnight
  • Bathe with cooler water avoid stripping skin of natural oils
  • Eat healthy fats may improve your skins moisture barrier
  • Drink plenty of water for supple skin
  • Use a humidifier if dry air is a trigger
  • Gently exfoliate feet regularly to rid them of dead skin cells
  • Avoid scratching or peeling flaky skin
  • Wear comfortable shoes allow feet to breathe

Winter Cedar Pollen Allergies

Mountain cedar is a type of juniper tree found mainly in South and Central Texas that pollinates in the winter, from December through March. In the areas where it grows, it is usually the only major pollen present during the wintertime. Mountain cedar can release such large amounts of pollen that the trees can appear to be on fire, with large clouds of smoke rising from the trees. Mountain cedar is a major cause of hay fever, and people who suffer from this form of pollen allergy typically refer to it as cedar fever.

Mountain cedar allergy symptoms include sneezing, itchy eyes and nose, nasal congestion, and a runny nose. With cedar fever, a person will not actually have a fever.

Other parts of the United States have related species of cedar, juniper, and cypress trees that cause springtime allergies. Because pollen is so similar within this family of trees, a person who is allergic to mountain cedar pollen will also be allergic to pollen from juniper and cypress trees.
