The sun is set to shine over most of the Easter weekend, but hay fever sufferers are being warned that we could see some of the worst pollen levels for years and one expert has described it as "nasty". Public Health Wales has warned of high pollen levels as temperatures are set to rise to highs of 18C.
The tree pollen season, which affects a quarter of people with hay fever, usually starts late-March to mid-May, while grass pollen, the cause of 95% of hay fever kicks in from late May to July.
Data from the Met Office suggests that due to climate change, we may be experiencing hay fever symptoms earlier than usual — and that those symptoms might be more severe — meaning it’s more important than ever to understand how to prevent and treat hay fever.
