Cold vs Allergies

Allergies that Trigger Cold-like Symptoms

Airborne allergens are responsible for symptoms that resemble the common cold. Airborne reactions are also grouped into two general categories—immediate and non-immediate reaction.

As the name suggests, immediate reaction for airborne allergens have instantaneous reactions such as sneezing and congestion; this group causes the cold-like symptoms. On the other hand, a non-immediate reaction is usually caused by contact dermatitis, a skin reaction which usually takes 2 days before symptoms such as rashes or hives appear.³

So, if you catch yourself constantly sneezing and dealing with a runny nose during allergy season – you’re not alone. An immediate reaction is the most common reaction and can be triggered by a range of allergens such as:⁴

• Pollen

• Mould spores

• Airborne pollution

• Cockroaches

• Pet dander

• Dust mites

Experiencing symptoms such as itchy eyes, itchy throat, and an itchy nose are the most common cold-like symptoms when exposed to these allergens. The body, naturally reacting to defend itself, is triggered by allergens to produce a chemical called histamine. This is the chemical that causes all your uncomfortable, cold-like symptoms.⁵

What Causes the Common Cold?

Unlike allergies which are caused by environmental and genetic factors, the common cold is caused by a virus, such as the rhinovirus.⁶ People contract the common cold from one another, and transmission of the virus tends to increase during early spring and late winter when people crowd together indoors.⁷ An infected person who sneezes or coughs can spread germ-carrying droplets in the air. When these droplets land on a healthy individual, the airborne germs make their way through the nose, mouth, or eyes and infect the person.

But unlike the rhinovirus, cold-like symptoms from allergies are not contagious. You don’t worry about ‘catching’ allergies when you stand next to someone who is sneezing because they suffer from an allergic reaction.

Cold vs Allergies Symptoms

When it comes to cold vs allergy symptoms, there are indeed some similarities, but there are tell-tale signs to differentiate between both conditions.

Some of the most common symptoms one should expect if they suffer from a respiratory allergy such as hay fever, include:⁷

• Sneezing

• Runny nose

• Nasal congestion

• Watery and itchy eyes

• Thin, clear mucus

You are likely suffering from allergies when the onset of symptoms happens abruptly and in certain environments. For example, you only experience these symptoms when you are playing with a pet or are at the park. The timeframe of allergy symptoms also lasts as long as you are exposed to the allergen.

The common cold on the other hand, produces symptoms such as:⁸

• Sneezing

• Runny nose

• Stuffiness

• Fever

• Thick mucus or phlegm that's greenish or yellow in colour

• Body ache and pains

With a cold, the onset of symptoms happens gradually and typically lasts 1-2 weeks.⁸ If you suspect that you’re having a cold, it is recommended to stay home and rest, especially since you may be contagious.

How Can One Manage Their Allergy Symptoms?

Managing allergies is no easy task. But if you aren’t already aware, it is best to consult with your doctor or an allergist to help determine your allergy triggers. Knowing what you’re allergic to is important as you can work around to avoid these allergens, or minimize your exposure to them.

Here are some tips and home remedies to help manage, and bring temporary relief to your cold-like allergies:

1. Practice healthy lifestyle habits: for example, consider keeping pets away from personal spaces (this means they can't sleep in your bedroom with you if they are making you sneeze).

2. Enforce basic hygiene: it's always a good idea to wash your hands often and avoid touching your face. This way, you can ensure you’re not transferring any allergens to your nose, eyes, or mouth.

3. HEPA filters: installing air purifier specifically made for allergies can help keep indoor air clean and free of floating dusts.⁹

4. Home remedies: you can often find something lying around the house that may help bring relief to your allergy symptoms, such as:¹⁰

   • Drinking warm liquids like broth or tea

   • Using a warm compress over your face to relief congestion

   • Direct warm steam (gently) to your nose to help open your nasal passageways

   • Irrigate your sinuses using a salt spray
