Cold or Allergies: Which is Behind Your Sneeze?

The symptoms are similar, but a few key clues can tell you which disease you're dealing with.

You might assume it’s just a cold and reach for the cold meds. You might be wrong.

Yeah, these are the main symptoms of the common cold. But they’re also symptoms of seasonal allergies. Outside of cold and flu season, it’s hard to know the difference.

So how can I tell the difference between a cold and allergies?

Cold and allergy symptoms mirror each other, but they result from very different immune responses. The common cold is a virus. Seasonal allergies are your body’s response to exposure to allergens like pollen, grass, mold, dust, and ragweed. While symptoms overlap, there are some that are distinct to each condition.

Common Cold and Seasonal Allergy Symptoms

Cold Allergies
Common Cough Sometimes
Common Runny or Stuffy Nose Common
Common Sneezing Common
Sometimes Fatigue and Weakness Sometimes
Common Sore Throat Sometimes
Rare Itchy, Watery Eyes Common
Sometimes Aches and Pains Never
Rare Fever Never
Thick and yellow or green Mucus Thin, watery and clear

More than half of cold and allergy symptoms are shared, but a few can clue you into which one is afflicting you. If you have general body aches and pains or are running a fever along with your other issues, a cold is the culprit. If your eyes are watering and your nose is too, your allergies are acting up.

Sorting through the symptoms is not always simple. When your mix of symptoms is too confusing to figure out, look instead at when they hit and how long they last. Symptoms that come on suddenly and generally happen at certain times of the year are most likely due to seasonal allergies. And they may last for several weeks until the pollen count or your exposure to allergens drops. A cold can last just as long, but most pass after three to 10 days. Cold symptoms also tend to come on gradually, developing one at a time over the course of a few days.

I feel terrible! What treatments stop a cold or seasonal allergies?

You’ve probably heard the phrase, "There’s no cure for the common cold." The same can be said for seasonal allergies. Like the cold virus, you have to wait it out and let the condition run its course. Depending on the length and severity of that particular allergy season, that can be a long, agonizing wait.

While you can’t stop a cold or allergies once they start, you don’t have to suffer for weeks until things pass. You can manage your cold and allergy symptoms with some tried-and-true remedies or over-the-counter medications.

Common Cold Treatments

Colds can be over before you know it. By the time symptoms drag you down, the virus could be on its way out. For colds that linger, the most common treatments are:

  • Rest – Take it easy to help with the fatigue and weakness, and let your immune system do its job. Rest is always a good idea when you’re fighting a bug, so enjoy the extra z’s.
  • Pain relievers – For Adults Acetaminophen is best for relieving cold symptoms. Take some Tylenol for any aches and pains.
  • Decongestants – Over-the-counter cold medications help your runny, stuffy nose by drying out and clearing up your nasal passages.
  • Cough suppressants – A cough is productive. It’s your body’s way of clearing mucus and germs from your throat and lungs. But if your cough is interfering with your sleep or severely affecting your day, cough syrup can provide temporary relief.
  • Water – Yep, good ol’ H2O! Water also helps with congestion and allows your mucus to flow freely. Drink plenty of water and avoid alcohol and caffeine to stay hydrated until your cold is gone. And if a sore throat accompanies your cold, gargle warm salt water to soothe it.

Seasonal Allergy Treatments

Since symptoms overlap, treatments do, too. Rest, water and decongestants all help manage allergy symptoms. There are several other treatments specific to seasonal allergies that can help you function:

  • Avoidance – It isn’t easy, but avoiding your allergy triggers is the best way to avoid their effects. If you aren’t exposed in the first place, you won’t experience the symptoms.
  • Antihistamines – This drug comes in pill or nasal spray form. It blocks the chemical released by your immune system, reducing sneezing, congestion, runny nose, and itchy, watery eyes. Some medications combine antihistamines and decongestants to get rid of even more symptoms.
  • Saline rinses and sprays – Like with a sore throat, salt water can provide relief in your nasal passages. Use a squeeze bottle or neti pot with your own solution or buy an over-the-counter spray bottle to dry and clear out your nose.

Nothing’s working. Is there anything else that can relieve my symptoms?

Yes, there’s more. Any time your symptoms last longer than expected or are still unbearable after trying at-home treatments, you should visit your primary care provider.

A lingering cold can lead to other issues, like a sinus infection, or be something else entirely. Get checked out if your cough, sore throat, congestion or headaches don’t go away — or get worse — after a couple weeks.

Allergies have many more treatments than what you can get at your local pharmacy. Prescription pills, nasal sprays, and allergy shots can provide relief when over-the-counter medications can’t. Some provide more immediate symptom relief; others should be taken for the long haul to keep ahead of the shifting seasons. Discuss your symptoms with your doctor or an allergist — a physician specially trained to diagnose and treat allergies — to find the best solution for you.
