Asthma: Reducing Triggers in the Home


Many of the most common triggers of asthma can be found in the home. If you or your child has asthma, you can take a few simple steps to reduce these triggers.

In the Bedroom

The bedroom is a particular problem area for many people with asthma. This is because bedding provides a home for microscopic insects called dust mites. Many people are allergic to their droppings, and this can cause asthma episodes. So use allergen-proof covers on pillows, mattresses and box springs. Get rid of stuffed animals. Keep surfaces dusted and clean. Wash bedding frequently in hot water.

In the Kitchen

In the kitchen, keep things clean. Cockroaches can worsen asthma symptoms, so wipe away crumbs and use roach control products. Keep garbage in a sealed container. Use an exhaust fan in your kitchen to vent moisture and fumes outside. Periodically, check for plumbing leaks.

In the Bathroom

In the bathroom, take steps to control mold and mildew. Use the vent fan when showering. Wipe down wet surfaces. Clean the tub or shower stall often. Instead of wallpaper, choose paint or tile. And wash rugs regularly.

Throughout the House

Throughout the house, remove things that collect dust, and keep surfaces clean. Get rid of carpets and large rugs wherever possible. Vacuum regularly, and use a vacuum with a filter that traps small particles.


Don't keep dogs or cats if you are sensitive to their dander. If you do have pets, bathe them frequently. Wash your hands and change your clothes after handling them. And never let pets in your bedroom.

Remove Other Triggers

Keep windows closed during high pollen seasons. Use air conditioning to control moisture levels in the house. Don't allow smoking in your home. Do not use a wood-burning fireplace. By reducing these common triggers, you can make your home a safe place for people who have asthma.
