As spring approaches, many of us look forward to enjoying the good weather and blooming flowers. However, for millions of hay fever sufferers, the sight of flowers and trees in bloom can signal the start of weeks or even months of misery. This year, experts are warning that the birch pollen count may be particularly high, leading to an increased risk of hay fever symptoms. In this article, we’ll take a closer look at the predicted birch pollen count, and what hay fever sufferers can do to protect themselves.
The UK is set to experience some of the highest ever levels of birch pollen, which affects around 25% of hay fever sufferers, this summer, according to Dr Beverley Adams-Groom, senior pollen forecaster at the University of Worcester. The only limiting factor would be a particularly wet April, which would limit pollen dispersal and result in less severe symptoms. Adams-Groom said it was too early to determine grass pollen levels. Birch trees’ biennial pattern of pollen production, coupled with increasingly warm summers, suggest that this year is likely to be a “severe season” with regard to birch pollen, she added. This year, the University has already seen hazel and alder tree pollen producing and emitting particularly high amounts of pollen. Those with hay fever have been advised to begin their treatment early in preparation for the season.
On a global basis, temperatures are rising, affecting pollen distribution and causing increases in allergic reactions. A US study published last year found that the amount of airborne pollen has increased by over 20% since the 1990s. Pollen seasons in Europe now last an average of two-and-a-half months longer than they did in the 1960s. In addition, pollen from ragweed – which grows in warmer temperatures – has now spread from the US to France and Italy. In Australia, many pollinating plants are no longer blooming in sequence in line with the seasons, causing what has been termed “mega pollen” seasons.
In March it was reported that a genetically engineered grass aimed at reducing hay fever was being tested in the US. The GM grass, which prevents seed formation, could reduce the amount of pollen produced by the plant by 99%. Critics have warned the grass may crossbreed with other plants, potentially leading to the creation of hybrid superweeds.
In conclusion, with the arrival of spring, comes the warning for hay fever sufferers to be cautious of predicted high levels of birch pollen. While vaccines and medications may provide relief, it is also important to take preventative measures such as avoiding exposure to pollen, keeping windows closed in the morning and evening and wearing a face mask while outdoors. By staying informed and taking necessary precautions, hay fever sufferers can mitigate the effects of seasonal allergies and enjoy the joys of springtime. Remember to pollen-proof yourself and be cautious when stepping out!
