Stay away from asthma triggers
It is important to know what things make your asthma worse. These are called asthma "triggers." Avoiding them is your first step toward feeling better.
Our homes can have asthma triggers, such as:
Asthma triggers - stay away from; Asthma triggers - avoiding; Reactive airway disease - triggers; Bronchial asthma - triggers
Stay Away From Smoking
If you smoke, ask your health care provider for help quitting. No one should smoke in your house. This includes you and your visitors.
Smokers should smoke outside and wear a coat. The coat will keep smoke particles from sticking to their clothes. They should leave the coat outside or away from your child.
Ask people who work at your child's day care, preschool, school, and anyone else who takes care of your child, if they smoke. If they do, make sure they do not smoke near your child.
Stay away from restaurants and bars that allow smoking. Or, ask for a table as far away from smokers as possible.
When pollen levels are high:
You can take several steps to limit exposure to dust mites.
Keeping indoor humidity at less than 50% will keep mold spores down. To do so:
Pets can Make Asthma Worse
Keep pets with fur or feathers outside, if possible. If pets stay inside, keep them out of bedrooms and off upholstered furniture and carpets.
Wash pets once a week if possible.
If you have a central air conditioning system, use a HEPA filter to remove pet allergens from indoor air. Use a vacuum cleaner with HEPA filters.
Wash your hands and change your clothes after playing with your pet.
Roaches and Rodents
Keep kitchen counters clean and free of food crumbs. Do not leave dirty dishes in the sink. Keep food in closed containers.
Do not let trash pile up inside. This includes bags, newspapers, and cardboard boxes.
Use roach traps. Wear a dust mask and gloves if you touch or are near rodents.
Other Triggers to Watch Out for
Do not use wood-burning fireplaces. If you need to burn wood, use an airtight wood-burning stove.
Do not use perfumes or scented cleaning sprays. Use trigger sprays instead of aerosols.
Discuss any other possible triggers with your provider and how to avoid them.
