One survey found out that more than half of parents questioned thought only asthma symptoms — and not their underlying causes — could be treated. More studies have shown that when many triggers inside the home and even schools — ranging from dust mites to cockroaches to molds — are removed, asthma symptoms can be drastically reduced. (See Chapters 4 and 12.)

Sometimes these triggers may be in the most unexpected places such as in upholstery or bedding. Therefore, removing triggers may mean more than just laundering or cleaning, but taking new steps to make lifestyle changes: For instance, you could have your child place dirty clothes into a hamper in another room or avoid use of products with fragrances such as scented candles.
