Predictions of a stormy summer are cause for concern among Asthma experts, who point out that heavy rain can trigger serious attacks in sufferers.
Speaking to The Telegraph, Dr Prasanna Sankaran, a specialist registrar in respiratory medicine at the Norfolk and Norwich hospital, said: "The new cases are often after heavy rain and thunderstorms which can trigger an attack."
According to Dr Sankaran, damp weather increases the likelihood of fungal spores being released from soil into the air.

UK weather forecasters continue to predict more thunder and lightning after storms swept across the country yesterday, bringing tornadoes to some areas.
Angela Jones, nurse specialist at Asthma UK, agrees that the risk of an attack increases during thunderstorms.
Jones told Huffpost Lifestyle: "Large quantities of pollen can be released into the air that trigger asthma symptoms and raise the risk of an emergency hospital admission."
"It also believed 'downdraughts' of cold air sweep up high concentrations of pollen and spores. These are thrust into the air, where they are broken up into smaller pieces that can penetrate deep into the lungs."
Jones highlighted that the increased risk of an asthma attack during volatile weather means it’s crucial for people keep their asthma medicines with them and windows closed to keep allergens out.
Asthma kills three people every day, and someone is admitted to hospital with a potentially fatal asthma attack every seven minutes in the UK, yet attacks and hospital admissions can be prevented by spotting and treating early warning signs.
Asthma UK are encouraging people with asthma to take The Triple A Test to help them find out their risk of having an attack and advise them what they can do to reduce it.
Ask if they have their reliever inhaler (usually blue) and where it is. You may need to get it out of their bag for them.
Encourage them to take one to two puffs of their reliever inhaler.
Make sure they are sitting up.
Encourage them to take slow and steady breaths.
Keep them calm and reassure them.
If they are still not feeling better after two minutes they can take two puffs of their reliever again and continue to do so every two minutes (up to a maximum of 10 puffs).
If they feel better, they should be OK to carry on with their day - but make sure they see a doctor as soon as possible (ideally the same day).
If at any time you are worried about them, call an ambulance.
If after 10 minutes they don't feel better and their inhaler doesn't seem to be helping them, then call an ambulance.
If the ambulance hasn't arrived after 10 minutes then the sufferer should repeat Step 6, until help arrives.
