What is hayfever?

Hayfever is a very common condition, affecting about 500 million people around the world. It is caused by an allergy, often to pollen and sometimes mould spores. The body's immune system over-reacts to the presence of external substances, as if they were something foreign. This results in irritation and inflammation.

What are examples of allergens?

Pollen, grass, dust mites, mould and even pet hair.

What are the symptoms of hayfever?

Hayfever symptoms vary from person to person and often involve symptoms of the respiratory tract such as sneezing, itchy and runny noses that can also become blocked as well as dripping down the back of the throat which can lead to coughing. This may also lead to headaches, itchy, puffy and watery eyes and itchy skin rashes.

What can I do to decrease my pollen exposure?

Be aware of the pollen count (usually broadcast along with the weather), and avoid areas of high pollen concentration, such as long grass, lawn mowing, and trees if allergic to these. If you need to work in these environments consider wearing a mask and goggles.

On high pollen count days, wash your hands and face frequently, particularly around the eyes with fresh, clean water.

Plant protective shrubs around your garden to protect you from wind blown pollen.

What is the difference between hayfever and persistent allergies?

Hayfever is seasonal and occurs during “hayfever season” (normally spring and summer). This is normally in line with seasonal changes in allergens such as pollens and grass. Persistent allergies can occur all year round and are a consequence of ongoing exposure by patients to allergens such as pet hair, dust mites and mould.

What can I do at home to decrease my allergy exposure?

Use an air-conditioner or filter when possible, at home, work, and in the car, to remove pollen and other allergens from the air.

Damp down any dust and vacuum your home regularly, to minimise the presence of pollen and dust.

Use a clothes dryer rather than washing line for drying bed linen, particularly when pollen counts are high.

Dust mites are often a major irritant and can cause or worsen suffering. Ensure that bedding is clean. Cuddly toys often harbour mites so wash if possible.
