Understanding the Difference Between Allergies and Colds
Both allergies and colds can cause similar symptoms like sneezing, coughing, and a stuffy nose which makes it hard to tell the difference between the two. Taking an allergies or cold symptoms quiz can help you figure out which one you're likely suffering from so you know how to find the right treatment.
Common Allergy Triggers
Allergies happen when your immune system overreacts to a harmless substance like pollen, pet dander, mold, dust mites, certain foods, insect stings, and medications. These substances cause your body to produce antibodies like histamine which lead to allergy symptoms. Common allergy triggers include:
- Pollen - From grass, trees, weeds
- Pet dander
- Dust mites
- Mold
- Certain foods - Peanuts, eggs, cow's milk, soy, wheat, fish, shellfish
- Insect stings - Bees, wasps, hornets, yellow jackets
- Medications - Penicillin or cephalosporins
Common Cold Causes
Colds are minor viral respiratory infections caused by over 200 viruses including rhinoviruses, coronaviruses, adenoviruses, enteroviruses, and more. You can catch a cold by:
- Inhaling airborne virus particles spread by coughing and sneezing
- Touching your eyes, mouth or nose after touching contaminated surfaces
- Sharing cups, utensils or other personal items with someone who has a cold
Allergy vs. Cold Symptoms Quiz
Timing & Duration of Symptoms
Take this quiz to start determining whether your symptoms are from an allergy or cold:
- When did symptoms start?
- Allergies: Often begin at the same time each year when exposure to an allergen resumes
- Colds: Can happen anytime of year after coming into contact with a virus
- How long do symptoms last?
- Allergies: Can be persistent and last for weeks/months during allergy season
- Colds: Usually last about 1-2 weeks
Common Allergy and Cold Symptoms
Although the timing associated with allergy vs cold symptoms differ, some of the actual symptoms often overlap including:
- Sneezing
- Coughing
- Stuffy, runny nose and nasal congestion
- Watery eyes
- Sore throat
- Headache
- Fatigue or tiredness
Unique Allergy Symptoms
However, those with allergies are also more likely to experience:
- Itchy eyes, nose, throat or skin
- Hives or skin rashes
- Dark under-eye circles
- Recurring ear infections
- Wheezing and trouble breathing
- Anaphylaxis - a life-threatening reaction involving swelling, trouble breathing, lowered blood pressure, dizziness and more
Unique Cold Symptoms
Those with viral colds may also have:
- Fever (allergies do not cause fever)
- Chills and body aches
- Sore throat
- Chest congestion and productive cough with colored mucus
Diagnosing the Cause of Symptoms
If taking an allergies vs cold symptoms quiz made you uncertain whether allergies or something else is to blame, speak to an allergist. They perform allergy testing to pinpoint your triggers and customize treatment so you find allergy relief.
Allergy Testing Methods
Examples of allergy tests used to diagnose allergies include:
- Skin prick test - Pricks extracts of potential allergens into the skin's surface to check for a reaction
- Intradermal tests - Injects small amounts of allergen extracts below the skin
- Blood tests - High levels of antibodies like Immunoglobulin E (IgE) indicate an allergy
- Challenge testing - Exposes you to suspected allergens through ingestion, inhalation, or skin contact to gauge your reaction
Determining a Cold
Colds cannot be confirmed with a diagnostic test. Doctors make a diagnosis of a viral cold based on typical symptoms as well as by ruling out bacterial infections and other medical issues with exams and other tests as needed.
Allergy & Cold Treatments
Once the cause for your stuffy nose and other symptoms are identified, these treatments can provide relief:
Allergy Medications
Medications used to control allergy symptoms include:
- Antihistamines - Block histamine to relieve sneezing, runny nose, itchy and watery eyes
- Decongestants - Reduces swelling and inflammation in nasal passages
- Leukotriene inhibitors - Blocks symptom-triggering leukotrienes
- Nasal sprays - Corticosteroid and antihistamine nasal sprays reduce congestion, sneezing, itching
- Allergy shots - Builds your tolerance to specific allergens over time through regular injections under the skin
Home Remedies for Colds
OTC medications can ease viral cold symptoms while your immune system fights it off. Other cold remedies include:
- Getting enough rest
- Staying well hydrated
- Using a cool-mist vaporizer
- Gargling with salt water
- Having hot tea with honey
- Taking OTC pain relievers like acetaminophen or ibuprofen
Preventing Allergies and Colds
While allergies and colds share some similarities, you have to handle each condition differently. But some basic preventive habits can help reduce your chances of developing either issue:
- Wash hands frequently using soap and warm water
- Avoid touching your eyes, mouth and nose
- Clean and disinfect commonly touched surfaces and objects
- Practice social distancing when viral illnesses are going around
- Keep distance from known allergy sources when possible
- Wear a protective face mask on high pollen count days
- Shower after outdoor activities to remove pollen
Learning your distinct allergy causes and symptoms through allergy testing can also help you practice better avoidance year-round. Tracking and managing symptoms is also useful so you discern allergy flare-ups from possible colds more easily.
FAQs
Can you have both allergy and cold symptoms at the same time?
Yes, it's possible to experience overlapping allergy and cold symptoms simultaneously if you have a viral infection while allergy season is underway. The symptoms may be more intense when both conditions are present.
Why do my allergy symptoms get worse at night?
Some allergies tend to worsen overnight because your circadian rhythms cause increased production of histamine and other compounds that trigger symptoms while you sleep.
Can pets cause allergy symptoms even if I'm not allergic?
Yes, pets that go outdoors can pick up pollen in their fur which then causes allergy symptoms when inside your home. Vacuuming and bathing pets regularly can help reduce this transferred pollen.
Will allergy symptoms go away on their own?
In some cases allergies, especially those to seasonal triggers like pollen, may lessen over time without treatment. However allergies often persist for many years if left untreated.
Can I develop new allergy triggers as an adult?
Yes, you can develop new allergies at any stage of life even if you never previously had issues. Common adult-onset allergies include those to bee stings, latex, and certain foods.
