Overview

• Window expert Danny Stalman of Plan-It Window says applying a thin layer of Vaseline around window frames and edges creates a barrier that traps pollen and lowers indoor allergen levels.
• The Met Office five-day pollen forecast warns of rising nettles and mugwort pollen and spores such as Alternaria, Cladosporium and Aspergillus under warm, dry conditions.
• The UK pollen monitoring network uses Met Office weather data and expertise from the National Pollen and Aerobiological Unit to deliver regional forecasts.
• NHS guidance suggests additional measures like applying Vaseline around nostrils, keeping windows closed, showering after outdoor exposure and using antihistamines, nasal sprays or eye drops.
• Experts also advise keeping window frames and sills free of mould and condensation to further limit pollen infiltration into homes.
