It is thought cleaning chemicals may damage the lining of the airways in babies if they are very frequently exposed to the products.

By three, these children were 37 per cent more likely to have a diagnosis of asthma and 35 per cent more likely to have a recurrent wheeze when compared with the quarter of families with the lowest cleaning product use

After years of warning about outdoor air pollution, caused by traffic and factory emissions, experts are increasingly concerned about the dangers of indoor pollution.
