With much of the UK continuing to experience showers this week, some hay fever sufferers may be wondering why they are still experiencing symptoms. According to Weldricks Pharmacy, Google Searches for “why is my hay fever worse when it rains?” increased by 3,450% in the last week alone.
Pharmacist and hay fever expert Allan Green said that while light rain can bring relief by clearing pollen from the air, heavy rain can actually stir up pollen, particularly when it is windy or later in the day. He added: “Sunshine also plays a big part. Plants rely on light for photosynthesis, so cloudy spells may temporarily reduce pollen levels — but once the sun returns, expect a sharp rise.
“That’s why it’s so important for hay fever sufferers, especially parents of children with allergies, to stay alert to the weather forecast and plan accordingly.”
Around 13 million people in the UK are thought to suffer from hay fever. Mr Green advised those struggling to avoid locations such as open fields, grasslands or areas with lots of trees.
He added: “Urban parks with more paved areas than trees or flowerbeds can also be a good option, or areas with natural windbreaks such as hills or mountains can help reduce the pollen in the air, regardless of the weather.
“If the rain gets heavy and you’re staying indoors, remember to close the windows fully to prevent pollen stirred up by the rain from being blown inside.
“Using an air purifier and drying laundry indoors can also help reduce exposure.
“By keeping an eye on weather changes and adjusting your routine accordingly, you can significantly ease hay fever symptoms — even on unpredictable spring and summer days.”
Pollen levels remained low over the bank holiday weekend but are expected to rise in some regions this week.
As of Wednesday, the Met Office forecast was predicting high pollen levels in the South West, London and South East, and the East of England on Saturday and Sunday.
