For many people, summer means outdoor adventures, warm evenings, and family barbecues, but for the more than 25 million Americans living with asthma, summer weather can be a trigger for dangerous flare-ups. High heat, humidity, and rising pollen levels can all worsen asthma symptoms, leaving many feeling like they’re missing out on seasonal activities.
The good news? With a few strategic steps, you can enjoy summer safely while keeping your asthma under control.
- Know Your Triggers and Track Air Quality
According to the Environmental Protection Agency, high ozone levels and pollen counts can trigger coughing, wheezing, and shortness of breath, especially in the afternoon when ozone peaks. Check the Air Quality Index (AQI) daily through apps like AirNow and plan outdoor activities for the early morning or evening on high-pollution days.
- Be Strategic About Outdoor Activities
Many people with asthma think they need to avoid exercise altogether in summer. However, staying active is vital for lung health.
Just be strategic. Pollen levels peak in late morning and early afternoon, so try jogging, cycling, or walking early or after sunset. Wearing sunglasses and showering after outdoor activities can reduce pollen exposure.
- Keep Your Medications Cool and Close
Heat can reduce the effectiveness of asthma medications. Keep inhalers at temperatures below 86°F and avoid leaving them in hot cars or direct sunlight. Carry a rescue inhaler when you’re outdoors and consider an insulated bag for storage during summer outings. If you find yourself relying on your rescue inhaler more than twice a week, talk to your doctor about adjusting your treatment plan.
- Manage Indoor Air Quality, Too
When outdoor air quality worsens, your home should be a safe haven. Keep windows closed on high-pollen or smoggy days, use HEPA filters in your air conditioner, and change filters regularly. Portable air purifiers can also help reduce indoor allergens, especially in bedrooms and living spaces.
- Don’t Ignore Early Warning Signs
Mild symptoms like chest tightness, nighttime coughing, or needing your rescue inhaler more often are warning signs that your asthma isn’t under control. Don’t wait for severe attacks. Schedule a check-in with your healthcare provider to adjust your plan if symptoms increase. Parents should also watch for reduced activity levels or frequent coughing in children.
