Allergic rhinitis – how to prevent allergic rhinitis?

The best way to prevent allergic rhinitis is to avoid the allergen that causes it.

But this isn’t always easy. Allergens, such as dust mites, aren’t always easy to spot and can breed in even the cleanest house.

It can also be difficult to avoid coming into contact with pets, particularly if they belong to friends and family.

Below is some advice to help you avoid the most common allergens.

House dust mites

Dust mites are one of the biggest causes of allergies. They’re microscopic insects that breed in household dust.

To help limit the number of mites in your house, you should:

consider buying an air-permeable occlusive mattress and bedding covers – this type of bedding acts as a barrier to dust mites and their droppings

choose wood or hard vinyl floor coverings instead of carpet

fit roller blinds that can be easily wiped clean

regularly clean cushions, soft toys, curtains and upholstered furniture, either by washing or vacuuming them

use synthetic pillows and acrylic duvets instead of woollen blankets or feather bedding

use a vacuum cleaner fitted with a high efficiency particulate air (HEPA) filter – it can remove more dust than ordinary vacuum cleaners

use a clean damp cloth to wipe surfaces – dry dusting can spread allergens further

Concentrate your efforts on controlling dust mites in the areas of your home where you spend most time, such as the bedroom and living room.

Pets

It isn’t pet fur that causes an allergic reaction, but exposure to flakes of their dead skin, saliva and dried urine.

If you can’t permanently remove a pet from the house, you may find the following tips useful:

keep pets outside as much as possible or limit them to one room, preferably one without carpet

don’t allow pets in bedrooms

wash pets at least once a fortnight

groom dogs regularly outside

regularly wash bedding and soft furnishings your pet has been on

If you’re visiting a friend or relative with a pet, ask them not to dust or vacuum on the day you’re visiting because it will disturb allergens into the air.

 

Pollen

Different plants and trees pollinate at different times of the year, so when you get allergic rhinitis will depend on what sort of pollen(s) you’re allergic to.

Most people are affected during the spring and summer months because this is when most trees and plants pollinate.

To avoid exposure to pollen, you may find the following tips useful:

check weather reports for the pollen count and stay indoors when it’s high

avoid line-drying clothes and bedding when the pollen count is high

wear wraparound sunglasses to protect your eyes from pollen

keep doors and windows shut during mid-morning and early evening, when there’s most pollen in the air

shower, wash your hair and change your clothes after being outside

avoid grassy areas, such as parks and fields, when possible

if you have a lawn, consider asking someone else to cut the grass for you

Mould spores

Moulds can grow on any decaying matter, both in and outside the house. The moulds themselves aren’t allergens, but the spores they release are.

Spores are released when there’s a sudden rise in temperature in a moist environment, such as when central heating is turned on in a damp house or wet clothes are dried next to a fireplace.

To help prevent mould spores, you should:

keep your home dry and well ventilated

when showering or cooking, open windows but keep internal doors closed to prevent damp air spreading through the house, and use extractor fans

avoid drying clothes indoors, storing clothes in damp cupboards and packing clothes too tightly in wardrobes

deal with any damp and condensation in your home

Allergic rhinitis – What are the signs and symptoms of Allergic rhinitis? Part One

Allergic rhinitis - a guide

Allergic rhinitis is inflammation of the inside of the nose caused by an allergen, such as pollen, dust, mould, or flakes of skin from certain animals.

It’s a very common condition, estimated to affect around one in every five people in the UK.

Signs and symptoms

Allergic rhinitis typically causes cold-like symptoms, such as sneezing, itchiness and a blocked or runny nose. These symptoms usually start soon after being exposed to an allergen.

Some people only get allergic rhinitis for a few months at a time because they’re sensitive to seasonal allergens, such as tree or grass pollen. Other people get allergic rhinitis all year round.

Most people with allergic rhinitis have mild symptoms that can be easily and effectively treated. But for some symptoms can be severe and persistent, causing sleep problems and interfering with everyday life.

The symptoms of allergic rhinitis occasionally improve with time, but this can take many years and it’s unlikely that the condition will disappear completely.

When to see your GP

Visit your GP if the symptoms of allergic rhinitis are disrupting your sleep, preventing you carrying out everyday activities, or adversely affecting your performance at work or school.

A diagnosis of allergic rhinitis will usually be based on your symptoms and any possible triggers you may have noticed. If the cause of your condition is uncertain, you may be referred for allergy testing.

What causes allergic rhinitis?

Allergic rhinitis is caused by the immune system reacting to an allergen as if it were harmful.

This results in cells releasing a number of chemicals that cause the inside layer of your nose (the mucous membrane) to become swollen and excessive levels of mucus to be produced.

Common allergens that cause allergic rhinitis include pollen – this type of allergic rhinitis is known as hay fever – as well as mould spores, house dust mites, and flakes of skin or droplets of urine or saliva from certain animals.

Treating and preventing allergic rhinitis

It’s difficult to completely avoid potential allergens, but you can take steps to reduce exposure to a particular allergen you know or suspect is triggering your allergic rhinitis. This will help improve your symptoms.

If your condition is mild, you can also help reduce the symptoms by taking over-the-counter medications, such as non-sedating antihistamines, and by regularly rinsing your nasal passages with a salt water solution to keep your nose free of irritants.

See your GP for advice if you’ve tried taking these steps and they haven’t helped. They may prescribe a stronger medication, such as a nasal spray containing corticosteroids.

Further problems

Allergic rhinitis can lead to complications in some cases. These include:

nasal polyps – abnormal but non-cancerous (benign) sacs of fluid that grow inside the nasal passages and sinuses

sinusitis – an infection caused by nasal inflammation and swelling that prevents mucus draining from the sinuses

middle ear infections – infection of part of the ear located directly behind the eardrum

These problems can often be treated with medication, although surgery is sometimes needed in severe or long-term cases.
