As the Texas summer heats up, it brings more than just sunshine and longer days. For individuals with respiratory or sleep conditions, the season also brings heightened health risks. Increased levels of ozone, pollen, and smog—combined with the strain of extreme heat—can significantly impair both breathing and sleep quality. At Lung & Sleep Specialists, we believe that awareness and proactive care are the keys to thriving all year long.
The Air We Breathe: A Summer Breakdown
Texas cities, particularly urban areas like Houston and Dallas, often experience spikes in air pollution during the summer. Here’s why:
- Ozone Levels Rise: Ground-level ozone forms when sunlight interacts with vehicle exhaust and industrial emissions. It’s a major trigger for asthma and COPD.
- Particulate Matter (PM2.5): Dust, smoke, and other small particles penetrate deep into the lungs, exacerbating chronic lung diseases.
- Pollen and Mold Spores: Summer plants, grasses, and increased humidity promote the growth of airborne allergens.
The Sleep-Air Quality Connection
Respiratory inflammation caused by allergens and pollutants doesn’t just make it harder to breathe—it also affects sleep. Poor air quality has been linked to:
- Increased sleep apnea events
- Greater nighttime awakenings due to congestion
- Overall reduced sleep quality
People with asthma or allergic rhinitis may notice increased coughing, wheezing, and postnasal drip during the night.
Heat Makes It Worse
Even without allergens and pollutants, high nighttime temperatures can prevent the body from cooling properly, making it harder to fall—and stay—asleep. This creates a vicious cycle of overheating, poor air circulation, and compromised rest.
Proactive Steps to Breathe & Sleep Better
To reduce exposure and improve sleep quality, consider these summer strategies:
- Use HEPA Filters: These high-efficiency filters trap airborne particles and are particularly helpful in bedrooms and HVAC systems.
- Change Filters Regularly: Every 30–90 days, depending on use and local air quality.
- Monitor AQI: Use AirNow or local weather apps to track the Air Quality Index and avoid outdoor activities on high-pollution days.
- Close Windows at Night: Pollen levels and humidity are highest in early morning hours.
- Invest in a Dehumidifier: Ideal indoor humidity is between 40–60% to avoid mold and dust mite growth.
- Keep Bedding Clean: Wash sheets weekly in hot water to reduce allergens.
