If you suffer from hayfever, it’s this time of year you might notice the first sudden surge of symptoms as the first ‘pollen bomb’ of the year hits. The Met Office has issued a red ‘high alert’ to warn those with allergies to be cautious this weekend as pollen levels are high. The NHS website states hayfever is usually worse between late March and September, especially when it’s warm, humid and windy. According to the Met Office the high levels this week are coming from tree pollen including birch, hornbeam, willow and ash. As well as fungal spores, Aspergillus Penicillium and Pleospora, which are in peak season. To help those who suffer from hay fever, we have rounded up the best antihistamines to use according to reviews on the Boots website, as well as a list of how to alleviate your symptoms. Most of the UK has been issued with the high-level pollen alert, including the East Midlands, East of England, London and the South East, Wales, South West and West Midlands. There is also a ‘very high’ alert in some parts on Easter Sunday (April 9). There’s currently no cure for hay fever and you cannot prevent it. However, you can do these things to mitigate symptoms. The NHS website says antihistamines are medicines often used to relieve symptoms of allergies, such as hay fever, hives, conjunctivitis and reactions to insect bites or stings.
