Dust Allergy and Hay Fever: Symptoms, Triggers and Relief

Reviewed by Dr Asma

Sneezing fits every morning, a blocked or runny nose, itchy watery eyes and a scratchy throat that never seems to go away: if this sounds familiar, you may not have a cold at all. In Pakistan, dust, pollen, smog, smoke and changing weather make allergic rhinitis, often called hay fever, very common. This guide explains dust allergy symptoms, triggers, how it differs from a cold, and practical ways to get relief.

What is dust allergy and hay fever?

Allergic rhinitis happens when your immune system overreacts to something harmless in the air, such as house dust mites, pollen, mould, pet hair or cockroach droppings. Your body releases chemicals that inflame the lining of the nose and eyes. Dust mites live in mattresses, pillows, carpets, curtains and soft toys, which is why symptoms are often worse at night and in the early morning, or when you dust and sweep the house.

Pollen allergy peaks in spring and also when certain trees and grasses bloom. In many cities, smog and air pollution irritate the airways and make allergic symptoms worse. Our article on smog and health has tips to protect your lungs and eyes.

Common symptoms

• Repeated sneezing, often in runs of several at a time
• Clear, watery runny nose or a blocked nose
• Itchy nose, throat, roof of the mouth or ears
• Red, itchy, watery eyes
• Postnasal drip with cough and throat clearing
• Tiredness, poor sleep and trouble concentrating
• Dark circles under the eyes in some children

Allergy or cold?

The two overlap, but a few clues help. A cold usually comes with sore throat, body aches and sometimes fever, and it clears up in a week to ten days. Allergy usually brings itching, clear mucus and symptoms that last for weeks or return at the same time each year, with no fever. For a full comparison, see our guide on cold versus flu. If your nose stays blocked with facial pain and thick discharge, it may be a sinus infection, so read about sinusitis.

Reduce your exposure at home

Avoiding triggers is the most effective step, and it costs little.

• Wash bedsheets and pillow covers weekly in hot water, and dry them in sunlight.
• Use dust mite proof covers on mattresses and pillows if you can.
• Damp dust and mop instead of dry sweeping, which just lifts dust into the air. Wear a mask while cleaning.
• Reduce carpets, heavy curtains and soft toys in the bedroom.
• Keep windows closed during high pollen days, dusty winds or smog.
• Fix leaks and damp walls to prevent mould, and keep bathrooms dry.
• Keep pets out of the bedroom if pet allergy is a problem.
• Shower and change clothes after being outdoors on dusty days.

Treatment options

Your doctor can match treatment to how severe and how frequent your symptoms are. Common approaches include antihistamine tablets or syrups for sneezing and itching, steroid nasal sprays that reduce inflammation in the nose, saline nasal rinses to wash out allergens, and eye drops for itchy eyes. Some antihistamines cause drowsiness, so ask your pharmacist which type suits you, especially if you drive or study. Nasal decongestant sprays should not be used for more than a few days, as repeated use can make the blockage worse.

For people with severe or year round allergy who do not improve, an allergist may suggest allergy testing and, in selected cases, immunotherapy. You can browse options in our allergy and hay fever category and related items under sinusitis. Always follow your doctor’s advice on how to use them.

Home care that helps

• Rinse the nose with clean, boiled and cooled or distilled water mixed with salt as advised by your doctor.
• Steam inhalation can ease a blocked nose for a short time.
• Drink plenty of fluids and keep the bedroom air clean.
• Use a clean cloth or tissues and wash hands often.

Allergy and asthma

Allergic rhinitis and asthma often travel together. If you have wheeze, tight chest, night cough or breathlessness along with nasal symptoms, speak to your doctor. Good control of nose allergy helps asthma, and our guide on asthma symptoms, triggers and inhaler use is worth reading. Nebulisers and inhalers are available in the nebulizers and inhalers section.

Children and allergy

Children also get hay fever, and it can be mistaken for repeated colds. Constant sniffing, mouth breathing, snoring and rubbing the nose upward are common clues. Never give adult medicines to children, and use only what the paediatrician has prescribed.

When to see a doctor

Book a visit if symptoms last more than two weeks, disturb your sleep or work, return every season, or do not improve with simple measures. Seek urgent care for swelling of the lips, face or tongue, difficulty breathing, wheezing that does not settle, or a widespread itchy rash after exposure to something you are allergic to.

Frequently asked questions

Can dust allergy be cured?

It cannot always be cured, but it can be controlled well with trigger avoidance and the right treatment. Some people improve with allergen immunotherapy.

Why are my symptoms worse at night?

Dust mites in bedding and lying flat both worsen nasal symptoms. Clean bedding often and raise your head slightly with a pillow.

Is hay fever contagious?

No. Unlike a cold, allergy does not spread from person to person, though allergy tendency can run in families.

Are antihistamines safe for daily use?

Many are safe for regular use under medical advice, but choose carefully if you get drowsy. Ask your doctor or pharmacist, especially in pregnancy or with other medicines.

Does smog cause allergies?

Smog does not create allergy in everyone, but it irritates the nose, eyes and lungs and can make symptoms much worse.
