Understanding Allergies and Colds: Common Symptoms

Distinguishing between allergies and a cold can be tricky. They share symptoms like a runny nose, congestion, and sneezing. It’s hard to tell which one you have without a closer look.
Overlapping Symptoms
Allergies and colds have many similar symptoms. A runny nose, congestion, and sneezing are common in both. For example, a cold makes your nose produce more mucus, causing congestion and a runny nose.
During an allergic reaction, your body releases histamine. This can also cause nasal congestion and more mucus.
Common Symptoms:
- Runny nose
- Congestion
- Sneezing
- Cough
Different Root Causes
Allergies and colds have different causes. Colds come from viruses, like the rhinovirus, which spreads easily. Allergies, on the other hand, are an overactive immune response to things like pollen or pet dander.
| Characteristics | Colds | Allergies |
| Cause | Viral infection | Immune response to allergens |
| Contagious | Yes | No |
| Duration | Typically 7-10 days | Can last as long as exposure to allergen |
| Fever | Sometimes present | Rarely present |
Knowing the difference between allergies and colds is key to managing symptoms. While they share some symptoms, their causes and characteristics are different.

But, you can catch a cold at any time, not just during cold and flu season.
Common Allergens and Their Seasonal Patterns
Allergies are caused by specific things in the environment, which change with the seasons. For example, pollen from trees, grasses, and weeds causes spring, summer, or fall allergies. Mold spores, which are more common in damp places, can also cause allergies, often in spring and fall.
Knowing what allergens are common at different times helps you manage your symptoms better. For instance, if you’re allergic to ragweed pollen, your symptoms will likely worsen in late summer and early fall.

This is important because it changes how you handle your symptoms and interact with others. If you have allergies, you can’t spread them to others, which is a big relief.
