What is asthma?
Asthma is a chronic lung disease that causes the airways to be inflamed, leaving less room for air to move through the lungs. This can cause trouble breathing and attacks of coughing, wheezing and chest tightness. Asthma leads to mucus in the lungs.
An asthma attack involves squeezing of the muscle bands around the airways, making it difficult to breathe. Left untreated, asthma attacks are dangerous and can lead to death. While asthma cannot be cured, it can be managed with medication prescribed by your child’s doctor, eliminating asthma triggers at home, and following your child’s Asthma Action Plan.
Every child has their own set of asthma symptoms before an asthma attack.
Why is there so much asthma in the Philadelphia region?
According to the Centers for Disease Control and Prevention, 5.8% of children in the U.S. have asthma. This rate is more than triple for Philadelphia children, with an asthma prevalence rate of 21%. In 2020, non-Hispanic Black and Hispanic children had over 4 times more asthma related hospitalizations in Philadelphia compared to non-Hispanic White children.
Asthma disparities may be explained by a combination of genetics and social determinants of health which include where children live, grow, learn and play. Indoor and outdoor air pollution both contribute to the high prevalence of asthma in the Philadelphia Region. Climate Change is expected to increase air pollution which can worsen asthma. Higher temperatures also increase the risk of mold, a common asthma trigger.
You can sign up for alerts on the air quality in your area by visiting airnow.gov to see when it is best to avoid playing outside during days with higher levels of air pollution in the air.
What can I do to protect my child?
If you suspect asthma, your first step will be to take your child to the doctor. They may make an asthma diagnosis and develop your child’s Asthma Action Plan . Make sure your child is taking their medication correctly as prescribed by their doctor.
Additionally, avoiding asthma triggers can prevent future asthma attacks. An asthma trigger is anything that can start an asthma attack. Each child will have different triggers.

- Physical activity
- Pollen
- Weather changes
- Colds and viruses

Ways to reduce exposure to asthma triggers

Never smoke in your home or areas where your child will be. The chemicals from smoke settle on surfaces and can trigger an asthma attack.
If you smoke, only smoke outside the home. Secondhand, and even thirdhand smoke (chemicals and nicotine that settle on surfaces), can trigger an asthma attack.
Wash bedding and fabric toys once a week in hot water
Use a HEPA vacuum to clean your carpets at least once a week.
Regularly mop floors and wipe surfaces with a damp cloth.
Avoid using cleaning products that have a strong smell. See this website for alternatives.
Fix any leaks and keep food in tightly sealed containers to discourage pests.
Urine, feces, saliva, hair and body parts from roaches and rodents are known asthma triggers. If you have pests, never use foggers or bug bombs. Use asthma friendly methods in getting rid of pests such as integrated pest management. Click on this link to learn more about safer ways to mitigate pests in your home.
Use a hypoallergenic mattress and pillow cover to protect your child from dust mites while sleeping.
Keep pets out of your child’s bedroom.
Avoid clutter as this can provide hiding places for pests. Minimize stuffed animals and carpet in bedrooms.
Sign up for daily air quality alerts at airnow.gov and don’t allow your child to play outside on poor air quality days.
If your child is allergic to pollen, check the pollen count in your area by visiting this website.
If physical activity is a trigger, ask the doctor if your child should take asthma medicine before playing.
