Winter allergy symptoms

There are many symptoms1 of indoor, winter allergies that you might experience. These include, sneezing, stuffy or runny nose, coughing and postnasal drip, and itchy eyes and nose. As you can see, the effects are not unlike the symptoms of the common cold, so we’ll go into some more detail on how you can tell the two apart.

What's the difference between colds vs. winter allergies

Winter allergies and colds share a few similar symptoms and can often be confused for the other. Time will often be the most telling factor of which one is affecting you. A cold will usually last between 3-5 days before eventually going away. If your symptoms last for longer than that, than you might be suffering from winter allergies. If you’re unable to locate the cause of your allergies, you may want to consult with your doctor.

There are a few other points of difference between winter allergies and colds, including²:

What allergies are worse in the winter?

A few allergies become more severe during the winter months but by far the most noticeable are your common indoor allergies, such as mold and dust. This is because you’ll be spending more time inside during the winter and don’t often have fresh air circulating throughout your home. On top of that, the dry air that comes with the colder temperatures can cause your allergy symptoms to seem more pronounced.

Are pet allergies worse in the winter?

Typically, yes. Allergies to pet dander are very common – some people can’t even be in the same room as a dog or cat if they have a severe case. The prolonged exposure to your pet being inside in a confined space during the winter months can inherently lead to a surge in symptoms. To help, bathe your pets weekly, if possible, to wash away dander and other allergens from their fur4.

What causes allergies during winter?

Surprisingly, many of the same allergens that trigger your allergies in the summer can be found in the winter. Because we spend more time indoors your allergies may even intensify due to more frequent and closer exposure. Some of the most common triggers2 in the winter include:

  • Mold
  • Airborne molds are a common cause of allergies all year round and can be present indoors and outdoors. Indoor mold contamination often depends on the moisture levels inside your house.

  • Dust Mites
  • Dust mites can be found practically everywhere inside your house. While there’s no getting rid of them completely, dialing up regular cleaning of surfaces and textiles in your home will help.

  • Dander
  • Pet dander can cause allergies at any time of the year, but as you hunker down for winter you might find you pet allergies to be worse due to all the time you and your pet are spending indoors.

  • Damp wood­
  • Moist cut wood that’s been stored outside can become a breeding ground for mold spores. Bringing that wood inside for fires is an open invitation to allergy triggers.

  • Temperate climates
  • Milder climates where there’s no, or few, hard freezes can result in the year-round presence of plant-based allergens like pollen

How to treat and get rid of winter allergies² ⁺ ³:

  • Wash hands and face often
  • Washing your hands and face will reduce the amount of allergens that will enter your body.

  • Wash bedding in hot water
  • As much as we may not want to think about this, dust mites and pet dander love to live on your bedsheets. Help minimize your exposure of these pesty allergens by washing your sheets, pillowcases, comforters and blankets in hot water (at least 130 °F)4 2-4 times a month.

  • Vacuum often
  • Vacuuming can go a long way in reducing the amount of dust mites and pet dander in your environment ­– two of the most common winter allergens. If you’re noticing your allergies are especially bad during the winter, this is an excellent first preventative step to take.

  • Use a humidifier
  • Dry air is common during the winter, and it becomes easier to find yourself dehydrated, which can exacerbate your symptoms. A humidifier can pump some much-needed moisture into the air and may even help reduce nasal congestion

  • Check firewood
  • Firewood can be a breeding ground for moisture and mold so make sure that you’re storing yours in a dry, and well-ventilated environment, preferably outside. Only bring in new logs as you’re ready to burn them.

  • Avoid smoke­
  • While a crackling fire might sound romantic during the winter, smoke can aggravate existing allergies. You can reduce your exposure to it with a glass door over your fireplace if you find it bothering you or cut back on the number of open fires you have.

  • Wipe your feet at the door
  • Many of the allergens found in your house were brought inside from your shoes or clothing. Removing your shoes at the front door or wiping your feet before you enter, especially after nature walks, is a simple step you can take towards reducing allergens in your home.

  • Be smart with storage
  • Seasonal items like winter coats, hats, gloves, scarves and even home décor items should be stored in air-tight containers when not being used to prevent buildup of dust and mold.

  • Carry a Kleenex® On-The-Go Pocket Pack
  • Winter allergies can sneak up on you like the first snowfall. That’s why it’s a good idea to always keep a Kleenex® On-The-Go Pocket Pack on-hand to provide immediate relief. These convenient tissue packs are made of 3-layers to comfort your face and help protect hands. Tuck them in your purse, gym bag, your child’s backpack or in the car so the comfort and superior softness of a Kleenex® tissue is always within reach.
