The Fourth of July is a time to gather, celebrate and enjoy the summer, but it’s also one of the most challenging days of the year for air quality. Between fireworks, grilling and increased travel, pollution levels often spike, making it harder for everyone—especially children, older adults and those with lung conditions—to breathe easy.
The good news? With a few simple choices, you can still enjoy the holiday while helping protect the air we all share.
Why air quality matters on the Fourth
Fireworks may be a beloved tradition, but they release a mix of harmful pollutants, including fine particles and gases like sulfur dioxide and carbon monoxide. These tiny particles can travel deep into the lungs, irritating airways and triggering asthma symptoms or other breathing issues.
In fact, air pollution levels can rise significantly during Independence Day celebrations, by as much as 42% on average, according to a study from the American Lung Association. That spike can linger into the next day, particularly on hot, still nights when pollutants get trapped near the ground.
Fourth of July also falls during peak ozone season in the St. Louis region, when high temperatures and vehicle emissions and fuel sources combine to form ground-level ozone. This is another pollutant that can cause coughing, chest tightness and difficulty breathing.
Simple ways to celebrate more cleanly
Small choices can make a big difference in reducing pollution and protecting lung health. Consider these air-friendly tips as you plan your holiday:
- Skip personal fireworks
Instead of setting off your own, attend a local, professional display. Community shows reduce the number of individual fireworks lighting up neighborhoods, helping lower overall emissions.
- Explore cleaner alternatives
Swap fireworks for glow sticks, LED lights or even drone and laser shows. These still create a festive atmosphere, without the smoke.
- Be smart about grilling
Grilling is another contributor to summer air pollution. Use propane or electric grills instead of charcoal, or delay grilling if an ozone action alert is in effect.
- Drive less, breathe better
Combine trips, carpool, bike or walk to gatherings when possible. Fewer vehicles on the road means fewer emissions contributing to ozone levels.
- Cut back on idling
Whether you’re waiting in line or picking up guests, turn your engine off. Reducing idling is one of the simplest ways to cut unnecessary pollution.
- Reduce waste at your gathering
Choose reusable or compostable party supplies and plan meals carefully to avoid food waste, keeping your celebration as sustainable as possible.
Protect your health while celebrating
If you notice smoky conditions or an elevated air quality forecast, take extra precautions. Staying indoors, limiting strenuous outdoor activity and checking daily air quality updates can help you make safer choices, especially for those with asthma or existing respiratory conditions.
Make it a cleaner celebration
Every action—big or small—adds up. This Fourth of July, celebrate not just independence, but a commitment to cleaner air for everyone.
