Overview

• The UK Health Security Agency (UKHSA) has issued red warnings for very high pollen levels across large parts of England and Wales, effective through May 2.
• The Met Office forecasts very high pollen levels in Wales, the West Midlands, East Midlands, and southern England, while northern England, Scotland, and Northern Ireland will experience high levels.
• Approximately one in four Britons—around 16 million people—suffer from hay fever, with symptoms including sneezing, coughing, itchy eyes, and fatigue.
• Tree pollen, particularly from birch, ash, and elm, is identified as the dominant allergen driving early-season allergic rhinitis symptoms.
• Experts recommend preventive measures such as using antihistamines, nasal sprays, HEPA filters, and minimizing outdoor exposure during peak pollen times.
