" Nothing works. I take a tablet daily and if I did not take it, it would be worse. "

But just how bad is it?

Dr Beverley Adams-Groom, one of the UK's leading pollen forecasters, said pollen grains may be Getting More potent due to CO2 levels in the atmosphere.

" Pollutants from traffic can interfere with the Respiratory System and reduce the threshold that people start to experience symptoms, " she added.

A warm May with sufficient rainfall, followed up by a warm June , meant there was also good grass pollen growth and production this Year , Dr Adams-Groom said.

Hay Fever is largely treatable, but some high count days can feel unbearable.

Studies show that some pollen types across Europe are already becoming more severe, with longer and earlier Seasons .

shows that Climate Change could be a driving factor behind changing patterns in the UK.

Pollen Seasons for different plants and trees happen at different times of the Year - broadly starting with tree pollen in mid-March, and ending with weed pollen by September.

Her research, exploring trends over 25 years, shows:

a changing climate may lengthen the normal UK season and make concentrations higher.

It means people who are allergic to both tree and grass pollen could get a " double-hit" as The Seasons become longer and overlap, according to Dr Sophie Farooque , Hay Fever expert and author of Understanding Allergy.

" You can end up breathing in both pollens simultaneously, rather than having a bit of a break from one to The Next , " She Said .

Pollen potency is not currently being monitored in the UK, but the says Climate Change could be Making It more intense.

Research shows that air pollution could potentially be making each pollen grain more potent and more likely to trigger an allergic reaction, according to Dr Farooque .

, in The Event that CO2 emissions double.
