If you're sneezing, congested and reaching for tissues, you may be wondering: Do I have a cold, or is it allergies?
It's a common question, especially during Indiana's spring and fall allergy seasons. While colds and allergies have several symptoms in common, a few key clues can help you figure out what's causing you to feel miserable.
To narrow down what may be going on:
- Look at your specific symptoms
- Track how long they’ve lasted
- Note what may have triggered them, such as time outdoors or being around someone who’s sick
The sooner you recognize the differences, the sooner you can find the right treatment and start feeling better.
Cold vs. Allergies: What's the Difference?
A cold is caused by a virus. It can happen any time of year and it’s contagious, meaning it can spread from person to person.
Seasonal allergies, on the other hand, occur when your immune system overreacts to substances such as pollen, mold or other environmental allergens. Allergies aren't contagious, but they can return year after year during certain seasons.
Side-by-Side Symptom Comparison
Use this chart as a quick guide to compare common cold and allergy symptoms. Keep in mind that symptoms can overlap, so consider how long they last, whether they follow a seasonal pattern and whether you may have been exposed to someone who is sick.
Symptom | Cold | Allergies |
| Fever | Sometimes | Rare |
| Body aches | Sometimes | Rare |
| Itchy, watery eyes | Uncommon | Very common |
| Sneezing | Common | Common |
| Runny nose | Common | Common |
| Congestion | Common | Common |
| Cough | Common | Sometimes |
| Sore throat | Common | Sometimes |
| Symptoms follow seasonal patterns | No | Often |
| Contagious | Yes | No |
Signs You May Have a Cold
Because a cold is caused by a virus, symptoms often develop gradually and may include:
- Stuffy or runny nose
- Sore throat
- Cough
- Sneezing
- Headache
- Mild body aches
- Occasional low-grade fever
Most colds improve within about a week, although a cough may linger longer.
Signs You May Have Allergies
Allergy symptoms often appear when you're exposed to a trigger such as pollen, mold, pet dander or dust mites.
Common allergy symptoms include:
- Sneezing
- Runny or congested nose
- Itchy or watery eyes
- Scratchy throat
- Postnasal drip
- Mild cough caused by drainage
Unlike a cold, allergies typically do not cause fever or body aches.
Itching Often Points to Allergies
If your eyes, nose or throat feel itchy, allergies are often the culprit.
"One of the clearest signs of seasonal allergies is itching, especially itchy or watery eyes," says Rashmin Adesara, MD, family medicine physician with Community Physician Network Family Medicine Care – Hillsdale.
"Colds can cause congestion and sneezing, too, but they are more likely to be accompanied by symptoms such as a sore throat, body aches or fever."
How To Assess Your Symptoms
When trying to determine whether you have a cold or allergies, consider these questions:
- Do your symptoms appear around the same time every year?
- Do you notice symptoms after spending time outdoors?
- Are several people around you sick?
- Have symptoms lasted longer than a couple of weeks?
Allergies often return during specific seasons and continue as long as you're exposed to the trigger. A cold usually runs its course and gradually improves over several days.
What Can Help?
If You Have a Cold
Getting plenty of rest, staying hydrated and managing symptoms can help you feel more comfortable while your body recovers.
If You Have Allergies
Avoiding known triggers and discussing treatment options with your healthcare provider may help reduce symptoms. Depending on your needs, options may include antihistamines, nasal sprays or other therapies.
When Should You See a Doctor?
Consider talking with your primary care provider if:
- Symptoms are severe or worsening
- Symptoms aren't improving as expected
- You're unsure whether you're dealing with allergies, a cold or another illness
- Breathing becomes difficult
- Symptoms interfere with your daily activities
A primary care physician can help identify the cause of your symptoms and recommend the most appropriate treatment plan.

How long do allergies last?
Symptoms can last for weeks or even months if you're continually exposed to the allergen causing them.
