How Does Air Quality Affect Asthma?


Those who suffer from asthma realize that the air they breathe affects their health. There may not be a known cure for this chronic illness, but an asthmatic who understands the relationship between air quality and asthma will be better prepared to handle triggers.

Does Air Quality Matter for People with Asthma?

Air quality matters more than most people realize. The air you breathe directly affects your lung health. Air quality is a big deal for everyone, but particularly for those who already have chronic lung conditions.

Poor air quality can be created by nature or can be man-made. Polluted air can result from dust, fires, or gases. An asthma sufferer must be aware of the quality of the air they are breathing and know how to respond to it.

One way an asthma sufferer measure pollutants in the air around them is to regularly check the Air Quality Index (AQI). The AQI is usually given by local news agencies during weather forecasts but can also be resourced online at

Preparation and Response

Air quality is an issue both outdoors and indoors. Make sure you know how to handle both areas.

Dealing with Outside Air Quality

If you have asthma, the first step you should take to guard against bad air quality is to consult a doctor. The general recommendation for those with asthma is to stay indoors when the AQI is at or above 101. Even if the index shows moderate readings, it is always a good idea to be careful when going outdoors or participating in physical activities.

Dealing with Indoor Air Quality

Since one of the main responses to a high AQI is to stay indoors, it makes sense that your indoor air quality should be clean, fresh, and healthy. Especially if you have asthma, it is important to learn and limit indoor pollutants.

Examples of indoor air pollutants include the following:

● Household cleaners
● Smoke from cooking, candles, fireplaces, or tobacco
● Dirt and dust from the HVAC system
● Dirty carpet and upholstery
● Old air filters
● Dusty furniture
● Pesticides
● Cosmetics, perfumes, and hair sprays

It may be necessary to remove certain chemicals or items from an indoor area, especially if it is obvious that these items cause asthmatic reactions. A few suggestions to improve indoor air quality are to:

● Prohibit smoking tobacco products indoors
● Ventilate the building by opening doors and windows
● Schedule routine HVAC and ductwork maintenance
● Change your air filters
● Use exhaust fans in kitchens, bathrooms, and laundry areas
● Install air filters that are certified for asthma and allergies
