“Thunderstorms can have a devastating impact on people with asthma and trigger an asthma attack which could be fatal”
The dangerous combination of volatile weather conditions and high pollen levels have been dubbed “thunder fever”.
The condition could include warm and humid air and could provide the perfect atmosphere for so-called “thunderstorm asthma”.
The pollen count is expected to remain at very high levels until at least Friday and the Met has Office issued another yellow warning for thunder.
Millions of asthma and hay fever sufferers could be endangered by the combination of stormy weather and sky-high pollen level – with potentially fatal symptoms.
The condition could trigger a dramatic rise in the number of dangerous asthma attacks.
Sonia Munde, of Asthma UK, said an estimated 3.3 million Brits had their asthma triggered by pollen.
She said: “Thunderstorms can have a devastating impact on people with asthma and trigger an asthma attack which could be fatal.
“Humid, stormy conditions break the pollen into much smaller particles, which are then inhaled more deeply into the lungs and can lead to life-threatening asthma attacks.”
With 5.4 million people in the UK currently receiving treatment for asthma, there’s a potentially life-threatening asthma attack in the country every 10 seconds, Asthma UK calculates.
And a massive 40% of the population are estimated to suffer from hay fever.
Hay fever, an allergic reaction to pollen, normally comes on between late March and September, when conditions are warm and humid, as they are now.
Even closing windows and doors does not completely protect sufferers, who are often forced to stay inside.
5.4 million people in the UK are currently receiving treatment for asthma: 1.1 million children (1 in 11) and 4.3 million adults (1 in 12). Every 10 seconds someone is having a potentially life-threatening asthma attack in the UK.
