Hayfever can make life miserable for those with the condition, especially those with severe symptoms. It can greatly interfere with the sufferer’s sleep, affect their daily routines, and disrupt their productivity at school or at work.
Thunder fever is an extreme form of hay fever and super pollen occurs when high humidity splits pollen grains into tiny, highly potent particles.
Thunder fever refers to specific thunderstorm and super pollen conditions that combine to increase the chances of hay fever and asthma sufferers experiencing symptoms which are particularly intense.
Asthma sufferers are also at risk of having an asthma attack due to thunder fever.

Is there any other advice for summer?
On staying well during the hot weather, Medical Director for St John Ambulance Dr Lynn Thomas, said: "We want everyone to enjoy themselves this summer, but also to take extra care in the warm weather and look after one another.
"If you're out and about in the sunshine, it's important to make sure you look after yourself by staying hydrated, keeping out of the sun at peak times, and by wearing sunscreen with a minimum SPF 30.
"I would also encourage anyone with elderly relatives and neighbours to check in with them, as any increase in temperature can be dangerous.
“Make sure you go out prepared, and can spot the early warning signs, as by knowing what action to take could stop it turning into something more serious.”
