Affinity Health, a leading provider of high-quality health cover, is helping families understand whether common respiratory symptoms are caused by spring allergies or a cold.

A runny nose, sneezing, congestion, and coughing can make it difficult to tell whether you have a cold or spring allergies. Pollen levels rise during spring, but cold viruses continue to circulate.

Knowing the likely cause can help you choose the right symptom relief and recognise when to seek medical advice.

“Spring allergies and colds can cause similar symptoms,” says Murray Hewlett, CEO of Affinity Health.

“However, things like itching, fever, how quickly symptoms start, and how long they last can help indicate which of the two you may be dealing with.”

Why Do the Symptoms Seem So Similar?

Both conditions affect the nose, throat, and sinuses, but they have different causes.

A cold is a contagious viral infection. It spreads mainly through particles released when an infected person coughs, sneezes, talks, or breathes, as well as through contaminated hands and surfaces.

Spring allergies, or hay fever, are not contagious. They occur when the immune system overreacts to harmless substances such as pollen or mould spores, causing sneezing, itching, inflammation, and watery eyes.

Look at How Quickly Symptoms Appear

A cold usually develops gradually, often one to three days after exposure to a virus. It may begin with a sore or scratchy throat, followed by sneezing, a blocked or runny nose, and coughing. Symptoms often worsen over the next two to three days.

Allergy symptoms can begin soon after contact with a trigger. You may feel well indoors but start sneezing after gardening, walking through grass, or opening windows on a dry, windy day.

Symptoms that return at the same time each year or worsen outdoors are more likely to be caused by allergies.

Itching Is an Important Clue

Itching is one of the clearest differences between allergies and a cold.

An itchy nose, throat, roof of the mouth, or eyes strongly suggests an allergic reaction. The eyes may also become red, watery, or swollen, and sneezing may occur in repeated bursts.

A cold can make the eyes watery, but it rarely causes persistent itching. A sore throat is more typical of a cold, although mucus dripping down the throat can also cause irritation in people with allergies.

Check for Fever and Body Aches

Seasonal allergies do not cause a fever. A cold can sometimes cause a mild fever, although this is more common in children than in adults.

Mild body aches, chills, and a general feeling of being unwell are also more likely to accompany a viral infection. Allergies can still leave a person feeling tired, particularly when congestion and coughing interfere with sleep, but they do not usually cause muscle aches.

A high fever, severe body pain, marked exhaustion, or a sudden onset of symptoms may indicate influenza, COVID-19, or another infection rather than an uncomplicated cold.

Consider How Long the Symptoms Last

Most colds improve within seven to 10 days. However, a cough or blocked nose can sometimes continue for up to two weeks, provided the symptoms are gradually improving.

Allergies can persist for weeks or longer while exposure to the allergen continues. Symptoms may ease on rainy or windless days and worsen when the weather is dry and windy, allowing more pollen to circulate.

The colour of nasal mucus is not a reliable way to distinguish between a cold and an allergy. Mucus can become white, yellow, or green during a viral cold as the immune response develops. This colour change does not automatically mean the illness is bacterial or that antibiotics are needed.

Managing Symptoms Safely

If spring allergies are causing your symptoms, reduce your exposure to pollen where possible:

• Keep windows closed on dry, windy days.
• Shower, wash your hair, and change your clothes after being outdoors.
• Avoid drying washing outside when pollen levels are high.
• Wear glasses or sunglasses outdoors to help protect your eyes.
• Use a saline nasal rinse to help clear pollen and mucus from your nose.

Antihistamines and certain nasal sprays may ease allergy symptoms. Some antihistamines can cause drowsiness, while decongestant nasal sprays may worsen congestion if used for too long. Ask a pharmacist or healthcare professional for advice before combining medicines or giving medicine to a child.

For a cold, get plenty of rest, drink enough fluids, and consider a saline nasal spray or suitable pain relief. Antibiotics do not work against cold viruses and should only be taken when prescribed for a bacterial infection.

Seek urgent medical help if you experience:

• Difficulty breathing or severe wheezing.
• Chest pain.
• Confusion or signs of dehydration.
• Blue or grey lips.

The Bottom Line

Persistent itching, watery eyes, sudden symptoms, and a recurring seasonal pattern are more likely to indicate allergies. A sore throat, body aches, gradual onset, and symptoms that clear within about two weeks usually point to a cold. Consult a healthcare professional if symptoms are severe, keep returning, do not improve, or worsen after initially getting better. People with asthma should take extra care, as both pollen and respiratory infections can trigger an asthma attack.
