Hay fever affects over 10 million people in England and there is currently no cure for the condition What is hay fever?

Hay fever is an allergic reaction to pollen, which can be released from a number of natural sources including trees or grass.

There is currently no cure for the condition, but many people are able to ease or control their symptoms with treatment.

You are typically more likely to get hay fever if it runs in your family, or if your family has a history of asthma or eczema.

Thankfully many people find their symptoms improve with age and can disappear completely in some cases.

Unluckily for sufferers, hay fever is set to get worse for millions of Brits this year as clouds of "super pollen" engulf the country.

Hay fever season started more abruptly than usual this year, when experts warned we were set for months of misery at the beginning of April.

In May, Britain's first ever hay fever map highlighted pollen hot spots in the UK.

Itchy eyes

A runny nose

Sneezing

Treatment can include taking antihistamines to prevent an allergic reaction, or corticosteroids (steroids) to help reduce swelling and inflammation.

You can usually get over-the-counter medication from your pharmacist, but if symptoms are persistent, it could be worth speaking to your GP for a prescription.

Symptoms can be alleviated by wearing sunglasses outdoors to prevent pollen from getting in your eyes.

You should also shower after being outside to remove any pollen from your body, or try to avoid natural areas when the pollen count is high.

A high count will usually be over 50 grains per cubic metre of air.

Other tips include putting Vaseline around your nose to trap pollen and avoid hanging clothes out to dry.

Hay fever is caused by an allergy to pollen, which is a powder released by plants that can cause eyes, sinuses, throat and nose to become irritated and swollen.

You may have an allergy to one or more of the following:

Grass pollen – which is typically released during the end of spring and start of summer

Tree pollen – released during spring

Weed pollen – released late autumn

People who grow up on farms are less likely to suffer allergies in later life, a study last year suggested.

Can babies get hay fever?

You can get hay fever at any age, but it usually starts in childhood or when you are a teenager.

It is more common in boys rather than girls, however in adulthood it affects both sexes equally.

These include:

Inflamed or weeping eyes

Unusual amounts of scratching

Rubbing their head frequently against furniture

You can take certain hay fever tablets when you are pregnant but you should always check with a pharmacist or GP first Can you take hay fever tablets when pregnant?

When you are pregnant you can take some hay fever medicines but are advised to steer clear of others.

It is best to get advice from your GP or pharmacist before taking any medicine when you are pregnant.

Often expecting mothers will be advised to take a nasal spray or eye drops before tablets.

Not all types of antihistamines are suitable during pregnancy, so it is important to consult your GP first.

According to the NHS website, Chlorphenamine is thought to be one of the safer antihistamines during pregnancy, but can cause drowsiness, so loratadine and cetirizine are typically preferred.

Pregnant Olympic champ Laura Kenny admitted to the Sun Online that she has always noticed the seasonal sniffles, but now she is expecting a child, her hay fever has been more unbearable than ever.
