You can try to reduce your child's exposure to things that can make asthma worse. These include:

• common air-borne allergens, such as dust mites, animal dander, mold, and pollen
• tobacco smoke and pollution
• chemical fumes
• cold air.

Here are some practical tips on how to make your home free of asthma triggers:

• Wash bedding and stuffed toys once a week in hot water to get rid of dust mites. Also, use airtight covers on the pillow and mattress.
• In the bedroom, remove carpets and use washable curtains or vinyl shades that you can clean with a wet cloth.
• Keep pets out of your child's bedroom.
• When the pollen or pollution levels are high, plan indoor activities with your child. For instance, play board games or have an indoor picnic.
• Let your child choose a scarf to wear over his or her mouth and nose on cold days.
• To zap mold, clean the bathroom and other damp spots with bleach and water.
• Send smokers outside to light up.
