Already struggling with itchy eyes, uncontrollable sneezing and a blocked nose? Experts are warning that pollen season may have started earlier than usual this year and, to the dismay of hay fever sufferers across the country, it appears to have arrived weeks ahead of schedule.
According to long-term pollen calendars produced by the University of Worcester, which are based on more than a decade of UK pollen monitoring data, hazel and alder pollen levels are supposed to be relatively low at this stage of the season. But according to the university’s latest forecast, alder pollen could already be reaching moderate to high levels on dry, mild days this week, and hay fever sufferers could already be feeling the effects.
Researchers say the early spike in pollen is likely linked to the abrupt shift in weather. “What we’re seeing here is that compared to last year, the pollen season has definitely started early,” says Dr Fiona Symon, an experimental officer in respiratory sciences at the University of Leicester. “Last year, we had quite a cold January and February, which pushed the start of the pollen season back. Whereas this year, with this mild spell, it has really brought everything forward.”
Trees tend to release pollen during warm, dry conditions. When milder weather arrives earlier than usual, it can trigger pollen to spread sooner and in greater amounts.
Birch pollen, which affects around a quarter of hay fever sufferers, typically doesn’t appear until late March or April. But Symon says earlier tree pollens such as hazel and alder can trigger similar allergic reactions weeks before birch pollen arrives. “Quite often, the people that react to alder and hazel will also react to birch and vice versa, because the allergens are quite closely related,” she explains.
Allergy UK recommends that people who regularly suffer from hay fever should try to start treatment with antihistamines before symptoms begin – ideally two weeks before pollen season starts. “If people know roughly when their symptoms usually start, it’s best to get ahead of the game,” Symon says. “Don’t wait until you start sneezing – start taking antihistamines a little earlier.”
Even when the pollen count is high outside, allergens can still make their way indoors through open windows, clothing and ventilation systems, meaning sufferers may experience symptoms at home.
One way to reduce airborne allergens indoors is with an air purifier, which can help ease symptoms indoors. “Air purifiers work by sucking in the air, and the pollen gets caught in the filters,” Symon explains. “They definitely work while you’re indoors, but if you don't follow the manufacturer's guidance in changing the filters, then they'll decrease in their efficiency.”

In her review of the Daewoo air purifier appliance tester Joanne Lewsley said the device “does the job without breaking the bank”, praising its compact design, quiet operation and low running costs. Designed for smaller spaces, the purifier features a three-stage HEPA filtration system that captures airborne particles such as pollen, dust and pet dander. Its lightweight build also means it can easily be moved between rooms.
