It is estimated that almost one third of the UK population suffers from hayfever, translating to over 20 million people.
The condition itself is an allergy to pollen, which is released by plants and trees across the country, reports Gloucestershire Live.
This pollen contains proteins that can swell the nose, eyes and sinuses, causing problems every spring and summer for sufferers.
Has hayfever struck early this year?
Lots of people have taken to social media in the past few weeks to complain about the hayfever season arriving prematurely due to the unusually warm February weather.
Lloyds Pharmacy have seen an increase in hayfever remedy sales in the past two weeks, with products flying off the shelves this week and yesterday specifically.
According to the Met Office, this is the result of warm air rising from Iberia and Northern Africa , which is in turn gradually raising temperatures.
It seems a world away from February last year, which saw the UK in the grip of the Beast from the East .
Speaking on the NHS website, Dr Glenis Scadding states there is no definitive start to the hayfever season, with weather conditions being the defining factor.
"Hayfever is usually an allergy to tree pollens in the spring, grass pollen on June and July and weed and mould pollens in the autumn," she said.
"Symptoms usually last throughout the season but vary from day to day because the pollen count varies according to the weather.
"It will be high if it's a warm, sunny day."
Although we are only in February, the prolonged warm weather could be causing a rise in the pollen count, and therefore causing a flair up in hayfever symptoms.
Despite having no known definitive cure, there are ways in which sufferers can relieve their symptoms.
The best way to treat hayfever is to avoid prolonged exposure to pollen by limiting time spent outside when counts are high.
Aside from this, over the counter treatments such as antihistamines are available and are designed to reduce the swelling caused by the allergy.
Corticosteroid nasal sprays and drops are another alternative, which again reduce swelling to make the condition more manageable
Enjoy the warmer February weather while it lasts though, with temperatures set to drop again next week as rain sweeps in from the Atlantic.
