Climate change lengthens hay fever season, experts warn
A global review links longer pollen seasons to warming, warning hay fever sufferers to brace for weeks more symptoms and offering practical tips to cope.
A major review by 65 scientists from around the world says climate change has lengthened the pollen season. The researchers found that flowering now starts earlier in many plants, with pollination occurring one to two weeks sooner between 2015-2024 compared with 1991-2000.
In Europe, trees such as birch, alder and olive show earlier pollination, and warm, dry days in the UK have helped pollen travel through the air, turning peak hay fever into a longer, tougher season for millions.
For many hay fever sufferers, symptoms like itchy eyes, sneezing and headaches can disrupt daily life and sleep. The prolongation could affect the quality of life for a large portion of people across the country.
We are seeing a prolonged season, says Professor Joacim Rocklöv from the University of Heidelberg, noting that more research is needed to determine whether climate change is also increasing the overall amount of pollen in the air. Anne Biggs, who supports allergy sufferers, adds that even moderate symptoms can significantly impact daily living.
What can you do to cope? Practical steps include checking local pollen forecasts, keeping windows shut on high-pollen days, wearing sunglasses outdoors, showering and changing clothes after being outside, and using air purifiers or appropriate allergy medications. Consulting a GP for persistent symptoms is advised.
The findings highlight the need for ongoing climate research and public health planning to support millions facing a longer pollen season.
