Why is asthma in the news?New research shows that 1 in 4 children who suffer from asthma think it stops them from having fun.
Half of the children surveyed said they've had problems joining in during lessons and school trips. 3 out of 4 said they've had problems in PE.
Why are asthma sufferers having these problems?Asthma UK's report says that 3/4 of teachers are not confident that they would know what to do if a child in their class had an asthma attack.
The study found that some teachers over-protect children with asthma and don't allow them to join in. Other teachers sometimes assume children are over-reacting to their symptoms.
Asthma UK is encouraging the government to make more guidelines on how teachers should deal with asthmatic children. They also want to get more nurses into schools.
