My child often coughs at night could it be the mattress he is sleeping on?
Mattresses, pillows, bedding and stuffed animals can emit fumes and collect dust mites – both of which can cause throat irritation and trigger asthma. Mattresses are often treated with chemicals to make them water and flame retardant. Beds can easily collect dust mites. Luckily, there are simple steps you can follow to control off gassing as well as the accumulation of dust mites.
