The Met Office is forecasting “high” pollen counts across the county on Friday and Saturday.

On Sunday and Monday this becomes "very high".

Here is what you need to know if you are planning to be out and about.

Hayfever — or allergic rhinitis — affects around one in four adults in the UK, according to Allergy UK.

Common hayfever symptoms include sneezing, coughing, a blocked or runny nose and sore, itchy eyes.

Symptoms are typically triggered when the immune system overreacts to pollen released by trees, grasses or weeds.

The season usually peaks between late March and September.

How to treat hayfever

Pharmacist Suhail Jamil, superintendent at Ashcroft Pharmacy, said: “Hayfever can be debilitating and really affect quality of life - especially for those who experience it for months at a time.

"The good news is that a combination of medication and simple lifestyle changes can make a big difference.”

Ashcroft Pharmacy recommends using a barrier cream around the nose, changing clothes and showering after being outdoors, keeping windows and doors closed at home and in the car, avoiding grass-cutting or spending time on freshly mown lawns and drying clothes indoors rather than outside.

Over-the-counter treatments such as antihistamines and nasal sprays can help ease the reaction.

Some antihistamines can cause drowsiness, so pharmacists recommend taking them at night or choosing non-drowsy options like Fexofenadine.

Decongestants and saline sprays can also relieve nasal symptoms.

Anyone with persistent or worsening hayfever, or who is experiencing breathing difficulties and chest tightness, should contact their GP.

Severe cases may require prescription medication or immunotherapy.
