Difference between Allergies and a Cold

It’s that time of year again when the cold and flu season is in full swing. Have you ever wondered what the difference between an allergy and a cold is? Most people think they are one and the same, but this isn’t actually the case. In this post, we will take a look at some of the key differences between allergies and colds so that you can better understand which one you may be suffering from. Stay healthy this season by arming yourself with knowledge!​

What is Allergy?

Allergy is a condition of the immune system. Allergies occur when the body’s immune system reacts to substances in the environment that are usually harmless. These substances are called allergens. Allergens can be found in many places, including:
-Pollen from trees, flowers, and grasses
-Dust mites
-Mold spores
-Pet dander
-Certain foods
-Insect stings or bites
People who are allergic to a substance will have symptoms when they are exposed to that substance. Allergic reactions can range from mild to severe. Mild reactions may cause sneezing, a runny nose, or itchy eyes. Severe reactions can cause difficulty breathing, swelling of the throat, and a drop in blood pressure. Allergic reactions can be life-threatening.

If you have severe allergies, you may need to carry an epinephrine auto-injector with you at all times in case of an emergency. If you think you have an allergy, see an allergist for testing and treatment. Allergists are medical doctors who specialize in diagnosing and treating allergies and asthma.

What is a Cold?

A cold is a viral infection of the upper respiratory system, including the nose, sinuses, throat, and bronchi. Symptoms typically include a runny nose, sore throat, coughing, and sneezing. Colds are caused by a variety of viruses, the most common of which are rhinoviruses. These viruses are spread through droplets of respiratory secretions, such as mucus or saliva. Colds are most commonly spread through close contact with infected people, such as during a handshake or a hug.

Colds can also be spread through contact with contaminated surfaces, such as doorknobs or countertops. There is no cure for a cold, but symptoms can be treated with over-the-counter medications. Most people recover from a cold within a week or two. However, some people may develop complications, such as pneumonia or bronchitis.

Difference between Allergies and a Cold

Although they may seem similar, allergies and a cold are actually caused by two different things. Colds are caused by viruses, while allergies are caused by your immune system reacting to a foreign substance – such as pollen or pet dander – that it perceives as harmful. Because of this, there are a few key ways to tell the difference between the two. For one, allergies tend to be more chronic – meaning they can last for weeks or even months – while a cold will usually only last for a few days.

Allergies also typically cause more subtle symptoms, such as watery eyes and a runny nose, while a cold will usually cause more general symptoms – such as fever, body aches, and fatigue. Finally, allergies are not contagious, whereas a cold can be spread from person to person. Knowing the difference between these two conditions is important in order to get the proper treatment.

Conclusion

Although both colds and allergies can cause congestion, sneezing, and itchy eyes, there are some key differences between the two. Allergies are caused by an immune response to a specific allergen, while a cold is most often caused by a virus. Additionally, allergies tend to last for weeks or even months, while a cold typically resolves in about one week.
