- Tells smokers to take it outside -- Secondhand smoke is a common asthma trigger. Encourage people to quit and make sure they smoke outside, not in your home or car.
- Sleep well, little dust mite! -- Dust mites are also common asthma triggers. Covering mattresses and pillows with dust-proof zippered covers and washing all bedding once a week in hot water will help keep the mites at bay.
- Watch air quality -- Poor air quality with high levels of ozone and particle pollution can worsen asthma symptoms and trigger asthma attacks. Watch for the Air Quality Index (AQI) during your local news, or check out this daily map with warnings for cities having a poor AQI day, provided by the Environmental Protection Agency. If the AQI in your community is poor, consider limiting outdoor activities.
- A little cleaning can go a long way -- Regularly dusting with a damp cloth and vacuuming carpet and fabric-covered furniture when asthma sufferers are out of the house can reduce dust exposures. Using a high=efficiency particulate air (HEPA) vacuum cleaner and filters can reduce exposure to dusts that may make your asthma worse.
- Defend your territory -- Household pets' dander, skin flakes, urine and saliva can trigger asthma. While it's best to keep the pets outside, keep them out of the bedroom if this is not possible.
- Pests are unwelcome guests -- Cockroaches are a pain to get rid of (they have been here for thousands of years, after all). Don't make things worse by leaving food or garbage out. Always clean up messes and spills, and store food in airtight containers.
- Be careful what you spray -- Instead of pesticide sprays, control pests by using baits or traps. If sprays are necessary, always circulate fresh air into the room being treated and keep asthma sufferers out of that room for several hours after any spraying.
- Breaking the mold is key -- Mold is another common asthma trigger. If you can control the moisture in your home, you can control the mold. Wash and dry hard surfaces to prevent and remove mold. Make sure to replace moldy ceiling tiles and carpet.
- Ventilation -- Reducing the moisture will control asthma triggers like mold, cockroaches and dust mites. Use exhaust fans or open windows when cooking and showering. Fix leaky plumbing or other unwanted sources of water.
- Plan, plan, plan -- Work with the doctor or healthcare provider to develop a written asthma management plan that includes information on asthma triggers and how to manage them.
