New research has found that damp and mould infested homes could not only trigger asthma attacks, but might also cause the onset of persistent asthma. Dr Pekkanen found that the severity of symptoms increased in direct proportion to the severity of the dampness in living areas. Visible mould and damp were 2-3 times more likely to be found in homes where asthmatic children lived than in homes without affected children. Some UK specialists are sceptical about these findings but there is little doubt that mould and dampness is unhealthy and it is a good idea to tackle these problems at source if you or your children suffer from respiratory allergies.
