Fall Allergies or a Cold? 4 Reasons You’re Still Sneezing

Still sneezing in October? Fall allergies are common, and they are often mistaken for a cold that won’t go away. The four biggest fall allergy triggers are ragweed pollen, mold from wet leaves, dust stirred up by your furnace, and more time indoors with pets. If your symptoms have lasted two weeks or more, it’s probably not a cold, and the good news is that it’s treatable.

4 Reasons You’re Still Sneezing This Fall

1. Ragweed pollen

Ragweed is the top fall allergy trigger across much of Ohio and Kentucky. It starts in late summer and keeps releasing pollen until the first hard frost. A single plant can produce huge amounts of pollen, and it travels far on the wind.

2. Mold from wet leaves

Piles of damp leaves are a perfect home for mold. Raking, jumping in leaf piles, or even walking through a wet yard can send mold spores into the air.

3. Furnace dust

The first time the heat kicks on for the season, it blows dust, dust mites, and debris that settled in your vents all summer.

4. Pets spending more time inside

As the weather cools, pets and people spend more hours indoors. That means more dander in the air you breathe.

Fall Allergies or a Cold: How to Tell

• How long it lasts. A cold usually clears up in 7 to 10 days. Allergies can last for weeks, as long as the trigger is around.
• Itchy eyes. Itchy, watery eyes point strongly toward allergies.
• Fever and body aches. Allergies do not cause fever. If you have a fever, it’s more likely a cold, the flu, or another infection.
• Mucus. Allergies usually cause clear, watery mucus.
• Timing. Symptoms that flare after raking or when the heat comes on suggest allergies.

How to Manage Fall Allergies at Home

• Check daily pollen counts and limit time outdoors when they’re high.
• Wear a mask when raking leaves or doing yard work.
• Change your furnace filter before you turn on the heat for the season.
• Keep windows closed on windy days.
• Shower and change clothes after spending time outside.
• Keep pets out of the bedroom.
• Try over-the-counter antihistamines, nasal steroid sprays, or saline rinses.

When to See a Provider for Allergies

Visit urgent care if:

• Over-the-counter medicine isn’t helping
• Your symptoms have lasted more than two weeks
• You have facial pain, pressure, or thick yellow-green mucus, which can mean a sinus infection
• Allergies are triggering wheezing or asthma symptoms
• You can’t sleep or function because of your symptoms

A CareFirst provider can help confirm whether it’s allergies or an infection, recommend or prescribe stronger treatment, and treat sinus infections. See our full list of illnesses we treat.

If allergies are making it harder to breathe, or you have asthma that’s flaring, don’t wait. A provider can check your breathing and adjust your treatment.

When Allergies Are an Emergency

Seasonal allergies are uncomfortable but rarely dangerous. Call 911 for any severe allergic reaction, such as swelling of the lips, tongue, or throat, trouble breathing, or hives with dizziness.

Frequently Asked Questions

What causes fall allergies?

The most common causes are ragweed pollen, mold spores from wet leaves, indoor dust stirred up by heating systems, and pet dander.

When does fall allergy season end?

Ragweed season usually ends after the first hard frost. Indoor triggers like dust and dander can continue all winter.

Can fall allergies cause a sore throat?

Yes. Postnasal drip from allergies can irritate the throat. A sore throat with fever is more likely an infection, so get it checked.

Can urgent care help with allergies?

Yes. Urgent care providers can diagnose allergies, rule out infections, and prescribe medications when over-the-counter options aren’t enough.
