IS IT ALLERGIES OR A COLD? HERE'S HOW TO TELL

HAY-FEVERSYMPTOMSBASICS

Every spring I go through the same thing. The sneezing starts, my nose runs, I feel tired. And every spring someone asks me if I'm sick. I'm not. It's just my body overreacting to tree pollen. Again.

But honestly, the symptoms do look a lot like a cold. Even I sometimes wonder for the first day or two. Here are the things I've learned to look for.

DURATION IS THE BIGGEST CLUE

Colds usually last 7 to 10 days. If your symptoms have been going on for two weeks or more, it's almost certainly allergies. Allergies stick around as long as you're exposed to the allergen, which during pollen season can be weeks or even months.

ITCHY EYES POINT TO ALLERGIES

Colds can make your eyes watery, but they rarely make them itchy. If your eyes are itching like crazy, that's a strong sign it's allergies. Same goes for an itchy nose or itchy throat.

FEVER MEANS IT'S A COLD

Allergies don't cause fevers. If you have a temperature, you're dealing with a cold or some other infection. The name "hay fever" is misleading. There's no actual fever involved.

CHECK YOUR SNEEZING PATTERN

Allergy sneezes tend to come in rapid bursts. Like five or six in a row. Cold sneezes are usually more spread out. If you're machine-gun sneezing, that's probably allergies.

LOOK AT THE MUCUS (SORRY)

Nobody wants to talk about this, but it's a useful indicator. Allergy mucus is usually clear and watery. Cold mucus often starts clear but turns thick and yellow or green after a few days. If it stays clear, think allergies.

TIME OF YEAR MATTERS

If your symptoms show up every March like clockwork, that's a pattern. Colds don't follow a calendar. Allergies do. Tracking your symptoms over time makes this really obvious. After a few seasons of logging how you feel, you can pretty much predict when your allergies will flare up.

THE ANTIHISTAMINE TEST

Here's a quick way to narrow it down: take an antihistamine. If your symptoms improve noticeably within an hour, it's almost certainly allergies. Antihistamines don't do much for cold symptoms.

When in doubt, see a doctor. But if you deal with this every year like I do, the pattern gets pretty obvious once you start paying attention.
